Favorable Ankylosis - 2 Digits C&P Exam Prep

What the examiner evaluates

• Which two digits are ankylosed and on which hand (dominant vs. non-dominant)
• Whether ankylosis is favorable (MCP or PIP fixed near neutral, fingertip-to-palm gap -2 inches/5.1 cm) or unfavorable
• Active and passive range of motion of all finger joints (MCP, PIP, DIP) and thumb joints (CMC, MCP, IP)
• Fingertip-to-proximal transverse palm crease gap measurement in centimeters
• Presence of angulation, rotation, or deformity at the ankylosed joint
• DeLuca factors: pain with motion, fatigability, weakness, incoordination, and effect of flare-ups and repetitive use
• Functional impact on grip strength, pinch, overall hand function, and activities of daily living
• Hand grip strength measurement (dynamometer if available)
• Presence of associated conditions: post-traumatic arthritis, degenerative arthritis, instability, swan neck or boutonniere deformity
• Use of assistive devices, braces, or splints
• Muscle atrophy (circumference measurement of both upper extremities)

Exam will include both a history interview and a hands-on physical examination. The examiner will observe your hand at rest, during attempted active motion, and during passive manipulation. Bring any splints, braces, or assistive devices you use. The exam may be conducted in person or via telehealth in some cases.

Prep checklist

• critical

  Identify and document your specific two affected digits

  Write down: (1) exactly which two digits are ankylosed (use proper names: thumb, index, long, ring, little finger), (2) which joint is ankylosed in each digit (MCP, PIP, DIP for fingers; CMC, MCP, IP for thumb), (3) which hand (right or left), and (4) which is your dominant hand. Bring this written note to the exam.

  before exam

• critical

  Review and understand the favorable vs. unfavorable ankylosis distinction

  Favorable: joint fixed near neutral/functional position, fingertip reaches within 2 inches (5.1 cm) of palm crease. Unfavorable: fixed in marked flexion/extension, gap >2 inches, or both MCP and PIP ankylosed in same digit, or angulation/rotation present. Knowing which category you are in helps you verify the examiner's documentation is accurate.

  before exam

• critical

  Gather all relevant medical records

  Collect X-rays, MRI reports, surgical reports, treatment notes, and any occupational/physical therapy records documenting the ankylosis. Bring copies or ensure they are in your VA file. Note dates of initial injury/diagnosis and any documented flare-ups or treatment.

  before exam

• critical

  Prepare a written flare-up description

  Write down: frequency (times per week or month), typical duration of flare-ups, specific triggers (cold, overuse, repetitive gripping, weather changes), what additional symptoms occur during flare-ups, and what activities you cannot do during a flare-up that you can partially do otherwise.

  before exam

• critical

  Document the functional impact on work and daily activities

  Create a specific list of activities you cannot perform or must modify: occupational tasks affected, hobbies given up, daily living activities requiring assistance or adaptive equipment. Be specific (e.g., 'cannot button shirt,' 'cannot carry a briefcase,' 'cannot type for more than 5 minutes without pain').

  before exam

• critical

  Note all DeLuca factors that apply to your condition

  Check which of these apply to your condition and prepare specific examples: (1) Pain with motion - at what degree or activity level? (2) Weakness - can you quantify reduced grip? (3) Fatigability - how quickly does hand function degrade with use? (4) Incoordination - specific instances of dropping objects or failing fine motor tasks. (5) Lack of endurance - how long can you perform hand tasks before limitation kicks in?

  before exam

• recommended

  List all medications and treatments for the condition

  Document all medications (pain relievers, anti-inflammatories, topical agents), frequency of use, whether they provide adequate relief, and any treatments tried (physical therapy, injections, surgery). Include any braces, splints, or assistive devices used.

  before exam

• recommended

  Identify and document any secondary/related conditions

  Note any pain, stiffness, or dysfunction in adjacent digits, the wrist, elbow, or shoulder that you attribute to compensating for your ankylosed digits. These may be separately ratable and should be mentioned to the examiner.

  before exam

• recommended

  Check your state's laws on exam recording

  Veterans have the right to record their C&P examination in most states. Check your state's one-party or two-party consent requirements. If you plan to record, notify the examiner at the start. Recording provides an objective record if there are discrepancies between your account and the DBQ.

  before exam

• optional

  Consider bringing a VSO or trusted individual

  You may bring a Veterans Service Organization (VSO) representative or a trusted person to your exam. While they typically cannot speak during the examination, their presence can help ensure accurate documentation and provide moral support.

  before exam

• critical

  Arrive with the condition at its typical or worst-day state

  Do not take extra pain medication to mask symptoms before the exam unless medically necessary. Arrive in the state that best represents your typical or worst-day functional level. If you normally use a brace or splint, bring it with you.

  day of

• critical

  Bring all braces, splints, and assistive devices

  Bring any finger splints, hand orthoses, jar openers, or other assistive devices you use. Showing the examiner these devices demonstrates the functional accommodation you require and supports documentation of disability severity.

  day of

• recommended

  Dress appropriately for hand examination

  Wear clothing that allows easy access to your hands without restriction. Avoid rings on the affected hand that might need to be removed. Remove nail polish if present to allow inspection of nail bed and digit color.

  day of

• recommended

  Review your written notes one more time

  Re-read your prepared descriptions of flare-ups, functional limitations, and DeLuca factors before entering the exam. You may bring your written notes into the exam and refer to them.

  day of

• critical

  Confirm the examiner documents which two specific digits are affected

  At the start of the exam, clearly state: 'I have favorable ankylosis of my [specific digit 1] and [specific digit 2] on my [right/left dominant/non-dominant] hand.' Ask the examiner to confirm this is being recorded correctly in the DBQ.

  during exam

• critical

  Ensure the fingertip-to-palm crease gap is measured

  When you flex your affected finger(s), observe whether the examiner is measuring the gap to the proximal transverse palm crease. If not, ask: 'Will you be measuring the gap between my fingertip and the palm crease?' Attempt maximum flexion during this measurement while reporting any pain that limits your effort.

  during exam

• critical

  Report pain at onset, not only at maximum movement

  As soon as you feel pain beginning during any movement test, say so: 'Pain begins at this point.' This documents the painful arc. Then continue if safe to your maximum tolerable range. This ensures the DeLuca pain factor is captured.

  during exam

• critical

  Describe worst-day function explicitly

  If today appears to be a better-than-average day, say: 'Today my condition is somewhat better than usual. On my typical bad days, [describe limitations].' The examiner should document your worst-day presentation per M21-1 guidance.

  during exam

• critical

  Report all DeLuca factors if not asked

  If the examiner does not ask about weakness, fatigability, incoordination, or lack of endurance, proactively state: 'I also want to mention that I experience significant weakness / fatigability / incoordination / lack of endurance when using this hand.' Do not assume the examiner will ask.

  during exam

• critical

  Do not minimize symptoms out of politeness or stoicism

  It is natural for veterans to understate symptoms. Remember: accurately describing your worst-day symptoms is not exaggerating - it is providing the complete clinical picture the examiner needs. If the examiner asks 'how are you doing?' answer specifically about your hand, not generally.

  during exam

• recommended

  Mention any deformity, angulation, or rotation of the ankylosed joint

  Point out any visible angulation or rotation to the examiner. Angulation or rotation at the fixed joint constitutes unfavorable ankylosis and may support a higher rating under DC 5222. Ensure the examiner documents the presence or absence of these features.

  during exam

• critical

  Confirm dominant hand is documented

  Explicitly state your hand dominance at the start: 'My dominant hand is my [right/left] hand.' This is critical for thumb involvement cases (30% vs. 20%) and should be confirmed in the DBQ.

  during exam

• critical

  Request a copy of the completed DBQ

  You have the right to request a copy of the DBQ after the examination is complete. Submit a written request to the VA Regional Office or use VA.gov/eBenefits. Review the DBQ for accuracy: correct digits identified, correct hand, correct gap measurement, DeLuca factors documented.

  after exam

• critical

  Review the DBQ for omissions and file a buddy statement if needed

  Check whether the DBQ accurately captures: (1) which two digits are affected, (2) dominant/non-dominant hand, (3) gap measurement in cm, (4) pain, weakness, fatigability, incoordination checkboxes, (5) flare-up description, (6) functional impact narrative. If items are missing or inaccurate, contact your VSO immediately to file a supplemental statement or request a new examination.

  after exam

• recommended

  Submit a personal statement (21-4138) to supplement the exam

  Within a few days of the exam, submit a personal statement documenting your worst-day functional limitations, flare-up frequency, and any additional detail the examiner may not have fully captured. This becomes part of the record the rater reviews.

  after exam

• recommended

  Consider nexus letter from treating physician

  If the DBQ examiner's opinion on diagnosis or nexus appears insufficient, ask your treating physician for a private nexus/medical opinion letter specifically addressing the ankylosis diagnosis, which specific joints are fused, and the gap measurement findings.

  after exam

Your rights during a C&P exam

• You have the right to a thorough examination by a qualified physician or physician assistant who is knowledgeable about musculoskeletal conditions and the DBQ requirements for hand and finger conditions.
• You have the right to record your C&P examination in most states. Check your state's recording consent laws beforehand. Notify the examiner at the start of the exam if you intend to record.
• You have the right to request a copy of the completed DBQ/examination report after the examination. Submit this request in writing to your VA Regional Office.
• You have the right to request a new examination if you believe the initial examination was inadequate, the examiner failed to document required findings (such as the fingertip-to-palm gap measurement), or the DBQ contains factual errors.
• You have the right to submit your own medical evidence, including a private independent medical examination (IME) or a nexus letter from your treating physician, to supplement or rebut the VA examination findings.
• You have the right to bring a Veterans Service Organization (VSO) representative or a trusted person to your examination for moral support, though they typically cannot speak or participate in the medical examination itself.
• You have the right to describe your worst-day symptoms and functionality during the examination. Per M21-1 guidance, the examiner should document your worst-day presentation, not only what they observe on that single day.
• You have the right to have all DeLuca factors (pain, weakness, fatigability, incoordination, lack of endurance, and effect of flare-ups and repetitive use) considered and documented in your examination report, per 38 CFR 4.40 and 4.45.
• You have the right to have your dominant hand documented and considered in the rating, as hand dominance affects the rating percentage for certain digit combinations under DC 5223.
• You have the right to appeal a rating decision you believe is inaccurate, including submitting a Higher-Level Review (HLR), Supplemental Claim with new evidence, or a Board of Veterans' Appeals (BVA) appeal.
• You have the right to have related secondary conditions (such as adjacent digit strain, wrist pain, or post-traumatic arthritis) considered for separate service connection if they result from your service-connected ankylosis.
• You have the right to a clear explanation of why your claim was rated at a particular percentage, including which diagnostic code was applied and what findings were considered.

Related conditions

• Unfavorable Ankylosis - 2 Digits If your finger gap exceeds 2 inches (5.1 cm), if both MCP and PIP joints in a digit are ankylosed, or if there is angulation or rotation at the fixed joint, the condition reclassifies as unfavorable ankylosis under DC 5222 with higher rating percentages.
• Favorable Ankylosis - Single Digit (Index Finger) If only one digit is ankylosed, a single-digit rating under DC 5225 (index finger) or DC 5226-5230 (other individual digits) may apply instead of or in addition to DC 5223. Evaluate whether one or both digits should be individually rated or combined under DC 5223.
• Favorable Ankylosis - Three Digits If a third digit of the same hand develops favorable ankylosis, the rating may increase to DC 5221 (three digits, favorable ankylosis). Document all ankylosed digits at the C&P exam to support potential future reassessment.
• Post-Traumatic Arthritis of the Hand Ankylosis of digits is frequently caused by or associated with post-traumatic arthritis. Degenerative changes in adjacent non-ankylosed joints may be separately rated under DC 5010 (arthritis due to trauma) or DC 5003 if supported by X-ray evidence.
• Limitation of Motion - Individual Finger Joints Adjacent non-ankylosed digits or joints may develop limited motion secondary to the biomechanical stress of compensating for the ankylosed digits. These may be separately rated under the appropriate limitation of motion DCs (5228, 5229, 5230).
• Boutonniare Deformity Boutonniare deformity (PIP flexion contracture with DIP hyperextension) may coexist with or be the mechanism leading to finger ankylosis. The examiner should document whether a boutonniare deformity is present as it affects joint position assessment.
• Swan Neck Deformity Swan neck deformity (PIP hyperextension with DIP flexion) may coexist with finger ankylosis, particularly in rheumatoid arthritis or post-traumatic conditions. Its presence should be documented as it can affect functional impairment assessment.
• Trigger Finger (Stenosing Tenosynovitis) Trigger finger can mimic ankylosis by causing a digit to lock in a flexed position. It is important to distinguish true bony/cartilaginous ankylosis from functional locking due to tendon sheath pathology, as the diagnostic codes and treatment implications differ.
• Gamekeeper's Thumb (Ulnar Collateral Ligament Injury) Chronic gamekeeper's thumb can progress to MCP joint instability and eventual ankylosis of the thumb MCP joint. If the thumb MCP is involved in your ankylosis, document the history of thumb ligament injury.
• Carpal Tunnel Syndrome Chronic hand conditions and compensatory use patterns from digit ankylosis can contribute to or exacerbate carpal tunnel syndrome. If you have symptoms of median nerve compression (numbness, tingling in first three digits), this may be a separately ratable secondary condition.
