What to Expect During Your Exam
Exam Overview
To document the degree of ankylosis of the long (middle) finger, determine whether the ankylosis is favorable or unfavorable, assess whether the ankylosed position causes functional limitation, and evaluate any secondary effects on adjacent digits or overall hand function.
What the examiner evaluates:
- Which joint(s) of the long finger are ankylosed - MCP (metacarpophalangeal), PIP (proximal interphalangeal), or both
- Whether ankylosis is favorable (gap of 2 inches or less between fingertip and proximal transverse crease of palm when maximally flexed) or unfavorable (gap greater than 2 inches, or both MCP and PIP ankylosed, or rotation/angulation present)
- Active and passive range of motion of the long finger MCP and PIP joints
- Whether both the MCP and PIP joints are ankylosed - this alone triggers unfavorable classification regardless of individual joint position
- Presence of angulation or rotation of bone at the ankylosed joint
- Grip strength and hand grip function
- Interference with function of adjacent digits (index, ring, little finger)
- Overall interference with hand function
- Whether amputation evaluation (DC 5153-5156) may yield a higher rating
- DeLuca factors: pain, fatigability, weakness, incoordination, and loss of endurance
- Flare-up history and frequency
- Assistive devices used (brace, splint, etc.)
Examination is typically conducted in person at a VA or contracted facility. Veterans may request that the exam be recorded; check your state's consent laws. Bring all prior medical records, imaging results (X-rays, MRI), and any private physician statements related to the long finger ankylosis.
Typical duration: 30-45 minutes
Fingertip-to-Palm Gap Measurement
The distance in centimeters between the tip of the long finger and the proximal transverse crease of the palm when the finger is flexed to its maximum extent. This is the primary measurement determining favorable vs. unfavorable ankylosis.
What to expect:
The examiner will ask you to flex your long finger as far as possible toward the palm and then measure the gap from the fingertip to the base of the palm (proximal transverse crease). The examiner will record this in centimeters on the DBQ.
Key thresholds:
- Gap of 5.1 cm (2 inches) or less — Favorable ankylosis - supports a 10% rating under DC 5226
- Gap greater than 5.1 cm (2 inches) — Unfavorable ankylosis - supports a 10% rating under DC 5226; may also support evaluation under amputation codes (DC 5153-5156) which could yield a higher rating
- Both MCP and PIP joints ankylosed (regardless of individual gap) — Unfavorable ankylosis classification; also consider whether amputation evaluation under DC 5153 is warranted and may yield a higher rating
- Rotation or angulation of bone present at ankylosed joint — Unfavorable ankylosis; may also support amputation evaluation under DC 5153-5156
Tips:
- Perform this measurement on your worst day or after activity to capture your true limitation
- Do not attempt to force the finger beyond its comfortable maximum - let the examiner observe your actual maximum flexion
- If your finger is fixed in extension, the gap will be large; clearly communicate this to the examiner
- Note that having BOTH the MCP and PIP ankylosed - even if each is individually in a favorable position - automatically qualifies as unfavorable
Pain considerations: If any attempt to flex the finger causes pain, tell the examiner immediately. Pain during testing is a DeLuca factor that must be documented. Per VA guidance, pain on movement alone can be a basis for a compensable finding.
Active Range of Motion (ROM) - Long Finger MCP Joint
How far you can actively flex and extend the MCP joint of the long finger under your own muscle power. Normal MCP flexion is approximately 90 degrees; normal extension is 0 degrees (or slight hyperextension).
What to expect:
The examiner will use a goniometer to measure the angle of flexion and extension at the MCP joint. Because ankylosis implies a fixed joint, the examiner will document the position at which the joint is fixed. If there is any residual movement, it will be measured.
Key thresholds:
- Joint fixed (ankylosed) - no active movement — Confirms ankylosis diagnosis; examiner documents fixed position in degrees
- Joint fixed in extension (0 degrees) — Unfavorable position - supports unfavorable ankylosis classification and potentially higher rating via amputation codes
- Joint fixed in flexion (functional position, approximately 20-30 degrees) — Potentially favorable position depending on gap measurement
Tips:
- Clearly describe the position your finger is permanently fixed in - whether it is straight (extended), bent toward palm (flexed), or twisted
- If the joint was surgically fused, bring documentation of the surgical position
- Document any associated pain or crepitus that occurs even with minimal attempted movement
Pain considerations: If you experience pain with any active or attempted motion, inform the examiner. Even a fixed joint can produce pain with attempted movement or pressure, and this must be recorded as a DeLuca factor.
Passive Range of Motion - Long Finger MCP and PIP Joints
The examiner moves your finger through its range without your active effort, to determine whether passive motion exceeds active motion and to confirm true ankylosis versus functional limitation.
What to expect:
The examiner will gently attempt to move your long finger MCP and PIP joints passively. In true ankylosis, passive ROM will equal active ROM (near zero). The DBQ specifically asks whether passive ROM equals active ROM.
Key thresholds:
- Passive ROM equals active ROM (both near zero) — Confirms true ankylosis as opposed to voluntary guarding; supports ankylosis diagnosis
- Passive ROM significantly exceeds active ROM — May suggest functional limitation rather than true anatomical ankylosis; examiner must document and explain discrepancy
Tips:
- Do not resist the examiner's passive movement - allow the joint to be moved to its natural end point
- If passive movement causes pain, say so clearly and immediately
- Passive testing confirms the structural nature of your ankylosis
Pain considerations: Pain with passive movement must be reported and documented. This is a separate DeLuca consideration from active motion pain.
Repetitive Use Testing (Functional ROM after 3 repetitions)
Whether repetitive use causes additional ROM loss, pain, weakness, or fatigability beyond the initial measurement. Per DeLuca v. Brown, the examiner must document the effect of repetitive use.
What to expect:
The examiner may ask you to perform repetitive gripping or attempted flexion-extension movements and then re-measure. Alternatively, you should proactively report how your symptoms change with repeated use.
Key thresholds:
- Additional functional loss after repetitive use — Supports a higher effective disability rating; examiner must document this on the DBQ
Tips:
- Before the exam, perform typical daily activities with your affected hand for 15-30 minutes so you present in your actual functional state
- Explicitly tell the examiner: 'After using my hand repeatedly, I experience increased pain, weakness, and difficulty gripping'
- Describe specific activities that worsen your condition: typing, gripping tools, opening jars, etc.
Pain considerations: Increased pain with repetitive use is a core DeLuca factor. Be specific: 'After 10 minutes of gripping, my pain increases from a 3/10 to a 7/10 and I cannot continue.'
Grip Strength Testing
Overall grip strength of the affected hand compared to the unaffected hand, documenting functional impact of the long finger ankylosis on overall hand use.
What to expect:
The examiner may use a dynamometer (grip-strength device) and will record results in the DBQ under hand grip fields. Asymmetry between hands is clinically significant.
Key thresholds:
- Measurable grip strength reduction in affected hand — Supports functional loss finding and may support a higher rating for overall hand dysfunction
Tips:
- Grip as firmly as you comfortably can - do not exaggerate weakness, but do not push through pain
- If grip causes significant pain, tell the examiner before the test begins
- Note that the long finger contributes substantially to overall grip strength
Pain considerations: Report any pain during grip testing. Pain that limits grip effort is itself a ratable factor.
Rating Criteria Breakdown
| Rating % | Criteria | Key Symptoms |
|---|---|---|
| 10% | Ankylosis of the long finger - both favorable and unfavorable ankylosis are rated at 10% under DC 5226. The distinction between favorable and unfavorable matters because unfavorable ankylosis may support a higher rating under amputation codes (DC 5153-5156). Favorable ankylosis: MCP or PIP joint ankylosed with fingertip-to-palm gap of 2 inches (5.1 cm) or less. Unfavorable ankylosis: gap greater than 2 inches, both MCP and PIP joints ankylosed (even if each in a favorable position), or presence of rotation or angulation of bone at the ankylosed joint. The Note under DC 5226 requires the examiner to also consider: (1) whether evaluation as an amputation is warranted; and (2) whether an additional evaluation is warranted for resulting limitation of motion of other digits or interference with overall hand function. |
CFR: 38 CFR 4.71a, DC 5226: 'Long finger, ankylosis of: Unfavorable or favorable 10 10.' Note: Also consider whether evaluation as amputation is warranted and whether an additional evaluation is warranted for resulting limitation of motion of other digits or interference with overall function of the hand. Per M21-1 guidance, unfavorable ankylosis is present when: the gap between fingertip and proximal transverse crease exceeds 2 inches (5.1 cm); both MCP and PIP joints are ankylosed (regardless of individual position); or rotation or angulation of bone exists at the ankylosed joint. |
10% Ankylosis of the long finger - both favorable and unfavorabl ...
Ankylosis of the long finger - both favorable and unfavorable ankylosis are rated at 10% under DC 5226. The distinction between favorable and unfavorable matters because unfavorable ankylosis may support a higher rating under amputation codes (DC 5153-5156). Favorable ankylosis: MCP or PIP joint ankylosed with fingertip-to-palm gap of 2 inches (5.1 cm) or less. Unfavorable ankylosis: gap greater than 2 inches, both MCP and PIP joints ankylosed (even if each in a favorable position), or presence of rotation or angulation of bone at the ankylosed joint. The Note under DC 5226 requires the examiner to also consider: (1) whether evaluation as an amputation is warranted; and (2) whether an additional evaluation is warranted for resulting limitation of motion of other digits or interference with overall hand function.
Key Symptoms
- Fixed, immobile joint at MCP and/or PIP of long finger
- Inability to flex or extend the long finger through normal range
- Pain with attempted movement of the ankylosed joint
- Reduced grip strength
- Interference with adjacent finger function (index, ring)
- Difficulty with fine motor tasks: typing, writing, buttoning
- Difficulty with gross motor tasks: gripping, carrying, lifting
- Fatigability of hand with use
- Swelling or deformity at joint
- Atrophy of intrinsic hand muscles from disuse
CFR: 38 CFR 4.71a, DC 5226: 'Long finger, ankylosis of: Unfavorable or favorable 10 10.' Note: Also consider whether evaluation as amputation is warranted and whether an additional evaluation is warranted for resulting limitation of motion of other digits or interference with overall function of the hand. Per M21-1 guidance, unfavorable ankylosis is present when: the gap between fingertip and proximal transverse crease exceeds 2 inches (5.1 cm); both MCP and PIP joints are ankylosed (regardless of individual position); or rotation or angulation of bone exists at the ankylosed joint.
How to Describe Your Symptoms
Joint Position and Degree of Ankylosis
How to describe:
Be specific about which joint is fixed (MCP, PIP, or both) and in what position (straight/extended, bent/flexed, sideways/angled). State the exact degree of fixation if you know it from prior X-rays or medical reports. If both joints are fixed, say so explicitly - this alone qualifies as unfavorable ankylosis.
Worst-day example:
“On my worst days - which happen after any sustained hand use - my long finger is completely locked straight (extended) at the PIP joint. I cannot bend it at all and it sticks out rigidly while I try to grip anything, causing my whole grip to be weak and unstable. The fixed finger catches on objects and I have dropped items because of it.”
What the examiner listens for:
Clear statement of which joint(s) are ankylosed, what position the finger is fixed in, and whether any functional movement exists. The examiner needs to determine favorable vs. unfavorable classification and whether both joints are involved.
Understatements to avoid:
Do not say 'my finger is just a little stiff' if it is truly ankylosed. Do not minimize by saying 'I manage okay' - describe the actual limitations. Do not fail to mention if BOTH the MCP and PIP are fixed, as this is critical to the unfavorable classification.
Fingertip-to-Palm Gap and Functional Flexion
How to describe:
Describe how far your long finger tip comes toward your palm when you try to make a fist. Use a comparison: 'I cannot close my hand into a full fist - there is a gap of about [X] inches between my fingertip and my palm.' If your finger is fixed in extension, describe how it protrudes when others are flexing.
Worst-day example:
“When I try to make a fist, my long finger stays almost completely straight. There is roughly a 3-inch gap between my fingertip and my palm. I cannot close my hand fully, which means I cannot grip a steering wheel, a tool handle, or a pen properly. The finger interferes with my ring finger as well, limiting its motion.”
What the examiner listens for:
The examiner needs the gap measurement to classify favorable vs. unfavorable ankylosis. A gap greater than 5.1 cm (2 inches) is unfavorable. The examiner will also measure this physically, but your verbal description helps establish the pattern of limitation.
Understatements to avoid:
Do not say 'I can almost close my fist' if the gap is significant. Be honest and specific about the distance. Bring a ruler or tape measure reference if needed to communicate the distance clearly.
Pain - Severity, Character, and Triggers
How to describe:
Describe pain using a 0-10 numeric scale for both baseline and worst-case scenarios. Specify location (at the MCP joint, PIP joint, surrounding soft tissue, radiating into palm or hand). Describe character: aching, sharp, burning, throbbing. Identify triggers: gripping, pressure on the joint, cold weather, repetitive use.
Worst-day example:
“At rest, my long finger pain is about a 3 or 4 out of 10 - a constant dull aching at the fixed PIP joint. When I try to grip anything firmly, the pain spikes to a 7 or 8 out of 10. After holding a steering wheel for 20 minutes during my drive here, the pain was an 8 and my entire hand felt weak and clumsy for the next hour.”
What the examiner listens for:
Pain on attempted motion, pain with repetitive use, pain at rest, and pain that limits functional activities. The DeLuca factors require the examiner to document pain-related functional loss even when ROM is already zero due to ankylosis.
Understatements to avoid:
Do not say 'it's not that bad' or 'I just ignore it.' Do not describe only current exam-day pain - describe your worst-day pain and typical pain during normal activities. Do not underreport rest pain.
Weakness and Grip Impairment
How to describe:
Describe specific tasks you cannot perform or struggle with: opening jars, using power tools, gripping a pen or pencil, squeezing a trigger, shaking hands, carrying bags. Quantify: 'I can only carry about 10 pounds before my hand gives out' or 'I drop objects 2-3 times per week because my grip fails.'
Worst-day example:
“I cannot grip a hammer or wrench at all - my hand opens up uncontrollably when I try. I have dropped my coffee mug twice this week. Writing more than a sentence or two causes cramping and pain throughout my hand. I cannot perform my job duties that require sustained gripping or fine manipulation.”
What the examiner listens for:
Objective weakness during grip testing and subjective reports of grip failure, dropped objects, and inability to perform work or daily activities. This is captured in the DBQ weakness and functional loss fields.
Understatements to avoid:
Do not say 'I just use my other hand' without also describing the limitation imposed on your dominant hand. Do not omit occupational impacts - these directly inform functional impairment findings.
Fatigability and Loss of Endurance
How to describe:
Describe how quickly your hand fatigues during use. Provide time estimates: 'After 5 minutes of gripping, my hand is exhausted and I need to rest for 30 minutes.' Note that fatigability is a separate DeLuca factor from weakness and both must be documented.
Worst-day example:
“On my worst days, I can grip for maybe 3-4 minutes before my hand cramps and becomes too painful to continue. Even light tasks like folding laundry or typing cause my hand to fatigue within 10 minutes. I need frequent breaks throughout the day just to manage basic tasks.”
What the examiner listens for:
Reported fatigue with use that is distinct from pain, and the time course of that fatigue. The examiner documents this under fatigability checkboxes and in functional loss narratives.
Understatements to avoid:
Do not conflate fatigue with weakness - describe both separately. Do not fail to mention how long recovery takes after your hand fatigues.
Incoordination and Fine Motor Loss
How to describe:
Describe specific fine motor failures: inability to pick up small objects (coins, pills, buttons), difficulty writing, inability to type accurately, problems with zipping, buttoning, or using touchscreen devices. The long finger is critical for pinch and precision grip.
Worst-day example:
“I cannot button a shirt with my right hand - I have to use my left hand exclusively. I drop pills trying to pick them up. My typing accuracy has dropped significantly because my long finger either freezes or hits adjacent keys. I can no longer perform tasks that require precision grip.”
What the examiner listens for:
Specific descriptions of coordination failures affecting work and daily activities. The examiner documents incoordination separately from weakness and pain on the DBQ.
Understatements to avoid:
Do not omit fine motor impacts just because you have adapted by avoiding those tasks. Adaptation is itself evidence of disability.
Flare-Ups - Frequency, Duration, and Severity
How to describe:
Describe flare-up patterns: how often they occur, what triggers them, how long they last, and how severe they are at peak. Per M21-1, if the examiner cannot examine you during a flare, your description is the primary evidence for flare severity.
Worst-day example:
“I have flare-ups approximately 2-3 times per month, typically triggered by cold weather, sustained hand use, or gripping vibrating tools. During a flare, my entire hand swells, the fixed joint becomes intensely painful (9/10), and I cannot use my hand at all for 2-3 days. I have missed work because of these flare-ups.”
What the examiner listens for:
Pattern of flares, functional impact during flares, and triggers. This information is documented in the DBQ flare-up section and affects the overall disability picture.
Understatements to avoid:
Do not say 'I don't really get flare-ups' if you experience periods where your symptoms are significantly worse than baseline. Any worsening episode qualifies as a flare.
Impact on Adjacent Fingers and Overall Hand Function
How to describe:
The DC 5226 Note specifically requires the examiner to consider whether additional evaluations are warranted for limitation of motion of other digits or interference with overall hand function. Describe how your fixed long finger affects the movement and function of your index and ring fingers.
Worst-day example:
“My fixed long finger physically blocks my ring finger from fully closing, reducing my ring finger's flexion by about 50%. My index finger compensates by trying to avoid the fixed long finger during grip, which causes additional strain. My overall hand function is significantly impaired - I would estimate I have lost about 60-70% of useful hand function compared to before the injury.”
What the examiner listens for:
Specific descriptions of how the ankylosed long finger mechanically interferes with adjacent digits, and how overall hand utility is reduced. This can support additional ratings for affected adjacent fingers.
Understatements to avoid:
Do not fail to describe secondary effects on other fingers. The regulatory note requiring consideration of adjacent digit impact exists precisely because this is commonly overlooked.
Common Mistakes to Avoid
Failing to distinguish whether one joint or both joints (MCP and PIP) are ankylosed
Whether one or both joints are ankylosed is the single most important factor in favorable vs. unfavorable classification. Having both MCP and PIP ankylosed is automatically unfavorable regardless of the gap measurement, and may support an amputation-level rating.
Instead: Review your medical records before the exam and know specifically which joint(s) are involved. Tell the examiner clearly: 'Both my MCP and PIP joints are completely fused' or 'Only my PIP joint is ankylosed.'
Impact: Favorable vs. unfavorable classification; potential upgrade to amputation-level codes (DC 5153-5156)
Not communicating the fingertip-to-palm gap clearly
The 2-inch (5.1 cm) threshold is the key measurement for favorable vs. unfavorable classification. If the examiner does not properly document a gap greater than 2 inches, you may receive a favorable classification when you qualify for unfavorable.
Instead: Measure the gap yourself at home before the exam. Bring that measurement in writing. During the exam, attempt maximum flexion actively and clearly - do not reflexively protect the joint. Ask the examiner to confirm the gap measurement.
Impact: Favorable vs. unfavorable classification; potential upgrade to amputation-level codes
Failing to mention interference with adjacent fingers and overall hand function
DC 5226 explicitly requires the examiner to consider additional ratings for limitation of motion of other digits or overall hand interference. Examiners may not pursue this analysis unless the veteran mentions it.
Instead: Proactively describe how the fixed long finger mechanically interferes with your ring finger and index finger. Describe overall grip reduction. Ask whether the examiner is documenting secondary effects on adjacent digits.
Impact: Potential additional rating(s) for affected adjacent fingers; overall combined rating
Failing to ask for evaluation under amputation codes when ankylosis is unfavorable
The DC 5226 Note requires consideration of whether amputation evaluation (DC 5153-5156) is warranted. An unfavorable ankylosis - particularly one with both joints fixed or with a large gap - may rate higher under amputation provisions.
Instead: If your ankylosis is unfavorable, ask the examiner directly: 'Has the question of whether amputation evaluation codes apply been addressed?' Submit a buddy statement or private physician letter requesting consideration under DC 5153.
Impact: Potential upgrade beyond 10% under amputation codes DC 5153-5156
Understating symptoms on the day of the exam because you are having a relatively good day
VA is required to rate your condition at its actual level of severity, including worst-day presentation. If you appear better than your average or worst functioning, the DBQ may capture an inaccurate picture.
Instead: Proactively tell the examiner: 'Today is not a typical day for me. On my worst days, which occur approximately X times per month, my symptoms are significantly worse.' Describe worst-day functioning in detail for each symptom category.
Impact: Any/all rating levels
Failing to report DeLuca factors (fatigability, weakness, incoordination, flare-ups) for an ankylosed joint
Veterans and sometimes examiners assume that because the joint is already fixed (ROM = 0), DeLuca factors are irrelevant. In fact, pain with attempted motion, fatigability, and weakness are all separately ratable and must be documented.
Instead: Explicitly tell the examiner about each DeLuca factor: pain with attempted or forced movement, how quickly your hand fatigues, any weakness or incoordination, and flare-up patterns. These go into separate DBQ checkboxes.
Impact: Functional loss documentation; may support higher combined rating when adjacent digits are also evaluated
Not bringing imaging (X-rays, MRI) to confirm ankylosis diagnosis and joint position
The examiner documents the diagnosis and may be more likely to clearly identify both ankylosed joints and any angulation or rotation if imaging evidence is present during the exam.
Instead: Bring copies of all relevant X-rays and imaging reports to the exam. Specifically highlight any reports that note both joints being fused, angulation, or rotation of bone.
Impact: Diagnosis confirmation; unfavorable classification support
Treating the exam as a medical appointment rather than a legal/administrative proceeding
The DBQ is a legal document that will be used to assign a disability percentage. Unlike a treatment visit where brevity is appropriate, at a C&P exam you must fully articulate every symptom, limitation, and functional impact.
Instead: Prepare written notes covering every symptom category. Take your time answering questions. If the examiner seems to be rushing through the functional history portion, politely say: 'I have additional symptoms that affect my daily function that I need to describe.'
Impact: Any/all rating levels

After the Exam
Your Rights During a C&P Exam
- You have the right to request a copy of the completed Disability Benefits Questionnaire (DBQ) after your examination. Contact the examination contractor (QTC, LHI, VES, or Optum) or your VA regional office to obtain this document.
- You have the right to record your C&P examination in most states. One-party consent states allow recording without notifying the examiner; two-party consent states require mutual agreement. Research your state's law before the exam.
- You have the right to submit a rebuttal to an inadequate or inaccurate DBQ. If the examiner failed to document required findings - such as DeLuca factors, adjacent finger impact, or consideration of amputation codes - you may submit a rebuttal with supporting evidence.
- You have the right to request a new C&P examination if the existing one is inadequate. An exam may be inadequate if it does not address all required regulatory considerations (such as the DC 5226 Note), is based on an inaccurate factual premise, or fails to document required measurements.
- You have the right to submit private medical opinions (nexus letters) from your own treating physicians. These opinions carry probative weight and can supplement or correct C&P exam findings.
- Under the PACT Act and VA benefit-of-the-doubt rule (38 CFR 4.3), when there is an approximate balance of positive and negative evidence, the VA must resolve the benefit-of-the-doubt in your favor.
- You have the right to claim secondary conditions - such as limitation of motion of adjacent fingers caused by the long finger ankylosis - as service-connected secondary disabilities under 38 CFR 3.310.
- You have the right to a higher-level review or Board of Veterans' Appeals (BVA) hearing if you disagree with the rating decision. You have one year from the date of the rating decision to file under the Appeals Modernization Act (AMA).
- You have the right to representation by an accredited VA claims agent, attorney, or Veterans Service Organization (VSO) representative at no cost to you during the rating process.
- You have the right to have your claim decided under the most favorable diagnostic code. If unfavorable ankylosis with both joints involved could yield a higher rating under amputation codes DC 5153-5156, you can request the examiner and rater evaluate under those provisions per the regulatory note.
Related Conditions
- Index Finger Ankylosis Rated under the same framework (DC 5225). Often co occurs with long finger ankylosis due to shared injury mechanisms. Long finger ankylosis frequently limits index finger motion due to anatomical proximity; an additional rating for index finger limitation may be warranted per the DC 5226 Note.
- Ring Finger Limitation of Motion The ring finger is directly adjacent to the long finger. A fixed long finger commonly obstructs ring finger flexion and grip. The DC 5226 Note specifically requires evaluation of whether additional ratings are warranted for interference with adjacent digits, making this a critical secondary consideration.
- Long Finger Limitation of Motion (non-ankylosed) Rated under DC 5229. If motion is severely limited but the joint is not fully ankylosed, DC 5229 may apply instead of or in addition to DC 5226. The examiner must determine whether true ankylosis exists or whether there is significant limitation of motion short of ankylosis.
- Post-Traumatic Arthritis of the Hand Post traumatic arthritis (DC 5010, evaluated as DC 5003) is a common underlying cause of finger joint ankylosis following injury. If arthritis is present in adjacent joints, additional ratings may be warranted under DC 5003 for those joints.
- Hand Grip Strength Reduction / Functional Loss of Hand Long finger ankylosis directly reduces overall hand grip strength and dexterity. The DC 5226 Note requires evaluation of interference with overall hand function, which may support an additional evaluation beyond the single digit rating.
- Amputation of Long Finger (DC 5153) Per the DC 5226 Note, the rater must consider whether evaluation under amputation codes is warranted for unfavorable ankylosis. When both MCP and PIP joints are ankylosed and either is in extension/full flexion, or there is rotation/angulation of bone, amputation level codes (DC 5153 5156) must be evaluated and may yield a higher rating.
- Carpal Tunnel Syndrome May co exist with or be secondary to chronic hand dysfunctional postures caused by long finger ankylosis. Altered grip mechanics can increase median nerve compression at the wrist, potentially causing carpal tunnel syndrome as a secondary condition.
- De Quervain's Tenosynovitis Overuse of the thumb and remaining functional fingers to compensate for the ankylosed long finger may cause tendinopathy or tenosynovitis in adjacent structures, potentially ratable as secondary conditions.
