Astragalectomy C&P Exam Prep

Ankle Dorsiflexion Range of Motion

What it measures: Ability to flex the foot upward toward the shin; normal is 0-20 degrees. Severely restricted in most astragalectomy cases due to loss of the talus.

What to expect: Examiner will use a goniometer to measure the angle of dorsiflexion. Testing will be done actively (you move it yourself), passively (examiner moves it), while weight-bearing (standing), and non-weight-bearing (sitting or lying). The examiner will note the point at which pain begins.

Pain considerations: Under DeLuca v. Brown, pain that limits motion before the anatomical endpoint must be documented. Tell the examiner: 'My motion stops here due to pain, not just because the joint won't go further.' Distinguish pain on motion from pain at rest.

Ankle Plantarflexion Range of Motion

What it measures: Ability to point the foot downward; normal is 0-45 degrees. Commonly significantly limited after talectomy.

What to expect: Same protocol as dorsiflexion - active, passive, weight-bearing, and non-weight-bearing. Examiner notes starting point and endpoint in degrees.

Pain considerations: Report the exact degree at which pain begins, not just the maximum degree reached. After repeated movements, communicate if pain increases - this documents DeLuca fatigability and reduced ROM with repetitive use.

Lower Extremity Length Measurement (Shortening)

What it measures: The measurable difference in leg length between the affected and unaffected extremity caused by the loss of the talus bone. DC 5274 is rated at 20% with a note to also consider shortening of the lower extremity.

What to expect: Examiner will measure both lower extremities, typically from the anterior superior iliac spine to the medial malleolus, and calculate the difference in centimeters. Standing height comparison may also be used.

Pain considerations: Leg length discrepancy can cause secondary low back pain, knee pain, and hip pain. Mention these to the examiner as they may support secondary service connection claims.

Muscle Circumference / Atrophy Assessment

What it measures: Difference in muscle mass between the affected and unaffected leg, indicating disuse atrophy from reduced weight-bearing and altered gait.

What to expect: Examiner will measure the circumference of both calves at the same anatomical location (typically 10 cm below the tibial tuberosity) using a tape measure.

Pain considerations: Atrophy is an objective finding. It corroborates your subjective reports of weakness and reduced function. You do not need to describe pain during this test, but you may mention that you avoid using that leg due to pain, which explains the atrophy.

Gait and Functional Ambulation Assessment

What it measures: How the absence of the talus affects your ability to walk, bear weight, maintain balance, and perform functional activities. Examiner observes for antalgic gait, limping, instability, and compensatory mechanisms.

What to expect: Examiner will likely observe you walking into and within the exam room. They may ask you to walk a short distance, possibly unassisted and with your assistive device. Note any limping, favoring of the affected side, or difficulty turning.

Pain considerations: Gait disturbance is a DeLuca factor. Accurately communicate: 'I can walk approximately [X] yards/blocks before the pain becomes severe enough that I have to stop or sit down.' This documents functional walking distance under real-world conditions.

20%

Astragalectomy (talectomy - surgical removal of the talus/astragalus bone). This is a flat 20% rating under DC 5274 for the procedure itself. VA must also evaluate whether the degree of lower extremity shortening warrants a higher rating under DC 5275. Additionally, residuals such as post-traumatic arthritis, ankylosis, or other secondary conditions may be separately rated if they meet criteria under other DCs (e.g., 5270 for ankle ankylosis, 5271 for ankle limitation of motion, 5003 for arthritis).

From 38 CFR: 38 CFR 4.71a, DC 5274: Astragalectomy rated at 20%, with reference to the shortening of the lower extremity rating. VA must consider whether shortening under DC 5275 warrants a higher evaluation. Under 38 CFR 4.59, painful motion must be considered. Under 38 CFR 4.40 and 4.45, functional loss due to pain, weakness, fatigability, and incoordination must be evaluated.

Pain

How to describe it: Describe the location (ankle, heel, mid-foot), character (aching, sharp, burning, throbbing), severity on a 0-10 scale at rest and with activity, and what makes it worse (walking, standing, uneven ground, stairs, prolonged activity, weather changes). Distinguish between your average day, your best day, and your worst day.

Example: On my worst days, the pain in my ankle and heel is a 9 out of 10. I cannot put weight on my foot for more than a few minutes without the pain becoming unbearable. I have to use my cane for even short trips around the house. The pain wakes me up at night if I roll onto that side, and I cannot stand at the kitchen counter long enough to cook a meal.

Examiner listens for: The examiner needs to document pain on motion (for 38 CFR 4.59), pain at rest (for functional loss), pain that limits ROM before the anatomical endpoint, and pain that increases with repeated use or during flare-ups. They will note whether pain is present on active motion, passive motion, weight-bearing, and non-weight-bearing per Correia requirements.

Avoid: Do not say 'it's manageable' or 'I deal with it.' Accurately state the impact: 'The pain significantly limits what I can do every day.' Do not minimize because you take pain medication - describe your symptoms as they are without medication, or describe how much medication you need to reach a 'manageable' level.

Functional Loss and Limitation of Motion

How to describe it: Explain what activities you can no longer do or can only do in a limited way because of the missing talus. Be specific about distances, durations, and frequencies. Address your ability to walk on uneven ground, climb stairs, stand for prolonged periods, use a ladder, drive, and exercise.

Example: On a bad day, I can walk maybe half a block before I have to stop and rest because of the pain and instability. I cannot walk on grass or gravel without serious risk of falling because my ankle has no stability. I have not been able to jog, hike, or stand for more than 10 minutes at a time since the surgery. I use a cane every day when I leave the house.

Examiner listens for: The DBQ asks the examiner to document disturbance of locomotion (field 534/547), interference with standing (532/545), and any instability. The examiner will also document functional loss caused by factors such as weakened movement, less movement than normal, and incoordination. These directly support the DeLuca analysis required for musculoskeletal claims.

Avoid: Do not say 'I get around okay.' Accurately describe what you cannot do. If you have modified your daily life to avoid pain (e.g., you no longer take walks, you sit instead of standing while cooking, you avoid stairs), describe these compensations - they are evidence of functional loss.

Flare-Ups

How to describe it: Describe what triggers your flare-ups (overactivity, weather, prolonged standing/walking, carrying weight), how often they occur (weekly, monthly), how long they last, how severe they are compared to your baseline, and what you have to do when they occur (rest, ice, elevate, take additional medication, use your wheelchair instead of cane).

Example: If I overdo it - even just going grocery shopping - I will have a severe flare-up for two to three days where my ankle swells to twice its normal size, the pain goes to a 10, and I cannot walk without my walker. This happens at least twice a month. During a flare, I am completely off my feet and dependent on others to do basic tasks.

Examiner listens for: Per DeLuca v. Brown, the examiner must document additional functional limitation during flare-ups or with repeated use over time. Field PUBLICDBQMUSCANKLE_312 specifically asks for documentation of the veteran's description of flare-ups. Provide concrete details about frequency, duration, and how much more limited you are during a flare compared to your baseline.

Avoid: Do not say 'I just take it easy when it flares.' Specifically describe the magnitude of additional limitation: 'During a flare, my ROM drops further, I cannot bear weight at all, and I require maximum assistance with daily activities for several days.'

Weakness, Fatigue, and Incoordination

How to describe it: Describe muscle weakness in the affected calf and foot, fatigue that develops with activity, and any incoordination (e.g., tripping, ankle giving way, inability to maintain balance on the affected side). Explain how quickly fatigue sets in compared to before the surgery or compared to your unaffected side.

Example: My calf on the operated side is noticeably smaller than my other leg, and it feels weak all the time. After walking more than a block, my leg feels like it gives out - it gets shaky and I feel like I am going to fall. My ankle turns unexpectedly when I step on anything other than a completely flat surface, and I have fallen twice in the past year because of this.

Examiner listens for: The DBQ has specific checkboxes for weakness (462, 476, 491, 506, 521), fatigability (446, 461, 475, 490, 505, 520), lack of endurance (448, 463, 477, 492, 507, 522), and incoordination (449, 464, 478, 493, 508, 523). These are all DeLuca factors. Each one checked adds to the documented functional loss beyond what ROM alone captures.

Avoid: Do not skip mentioning these symptoms just because the examiner does not ask directly. Proactively state: 'I also experience significant weakness and fatigue in that leg, and my ankle gives way unexpectedly.' These are separate from ROM and can support a higher combined functional disability finding.

Impact on Daily Life and Work

How to describe it: Describe the concrete impact on your daily activities, occupational limitations, social life, sleep, and ability to care for yourself. Be specific about what you can and cannot do, and how long it takes you versus how long it would take an uninjured person.

Example: I had to leave my job as a warehouse worker because I cannot stand or walk for extended periods. I now work a desk job but even that is difficult because I cannot sit with my foot in a normal position for long. I cannot play with my children on the ground without serious pain. I sleep with a pillow under my ankle every night and I still wake up in pain several nights per week.

Examiner listens for: Field PUBLICDBQMUSCANKLE_751 asks the examiner to document functional impact. Field PUBLICDBQMUSCANKLE_315 asks for the veteran's own description of functional loss. The rater will use these to evaluate whether the 20% rating under DC 5274 accurately reflects total disability or whether secondary conditions like arthritis or shortening warrant additional ratings.

Avoid: Do not say 'I manage.' Accurately describe all the ways this condition has changed your life. If you have had to give up hobbies, change jobs, modify your home, rely on others for help, or limit your social activities, these are all relevant and should be communicated clearly.

Instability and Falls

How to describe it: Describe ankle instability specifically - does the ankle give way without warning? Have you fallen because of it? How often do you feel like you might fall? Do you avoid certain surfaces or activities because of fall risk?

Example: My ankle gives way at least two or three times a week without warning. I have actually fallen twice in the last six months - once on a sidewalk crack and once on stairs. I now grip handrails with both hands and I avoid any surface that is not completely flat. I will not go outside alone at night because the instability in low light is dangerous.

Examiner listens for: Instability of station is documented on fields 540 and 553. Falls history and ankle giving way support findings of incoordination, instability, and functional loss. The examiner may also note this supports the need for an assistive device.

Avoid: Do not downplay falls or near-falls. Accurately report them. A history of falls is an objective safety and functional concern that directly supports your disability rating and may also support SMC or adaptive equipment claims.
