Long Finger Ankylosis C&P Exam Prep

Fingertip-to-Palm Gap Measurement

What it measures: 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.

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

What it measures: 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.

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

What it measures: 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.

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)

What it measures: 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.

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

What it measures: 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.

Pain considerations: Report any pain during grip testing. Pain that limits grip effort is itself a ratable factor.

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.

From 38 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.

Joint Position and Degree of Ankylosis

How to describe it: 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.

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.

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.

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 it: 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.

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.

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.

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 it: 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.

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.

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.

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 it: 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.'

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.

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.

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 it: 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.

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.

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.

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 it: 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.

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.

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.

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 it: 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.

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.

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.

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 it: 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.

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.

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.

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.
