  1. Veterans Benefits Administration Compensation and Pension Service Musculoskeletal System January 2008

  2. Musculoskeletal System Objective Demonstrate, through test cases and exercises, a general understanding of the basic principles for applying the Rating Schedule in evaluating musculoskeletal disabilities.

  3. Musculoskeletal System References: • 4.1 – 4.31 & 4.40 – 4.73 • M21-1MR, III.iv.3.D.19 • M21-1MR, III.iv.6.D.18 • M21-1MR, III.iv.4.A • Training Letter 02-04 • Fast Letter 04-22 • VAOPCPREC’s 23-97 & 9-2004

  4. Evaluation Considerations • Functional Loss (38 CFR 4.40) • DeLuca v. Brown, 1995: Requires we consider not only limitation of motion, but also: - weakened movement, - excess fatigability, - incoordination, & - pain when evaluating these disabilities.

  5. Evaluation Considerations The examiners should indicate if pain could significantly limit functional ability during flare-ups or repeated use over time. They should express this in degrees of additional range of motion lost.

  6. 38 CFR 4.45 Exams Examiners should provide history and objective findings, as well as findings of: • Less movement than normal • More movement than normal • Weakened movement • Excess fatigability • Incoordination • Pain on movement

  7. Major Joints • Shoulder • Elbow • Wrist • Hip • Knee • Ankle

  8. Groups of Minor Joints Multiple involvements of the: • Interphalangeal, metacarpal and carpal joints of upper extremities • Interphalangeal, metatarsal and tarsal joints of the lower extremities • Cervical vertebrae • Dorsal vertebrae • Lumbar vertebrae • Lumbosacral articulation and sacroiliac joints (rated on disturbance of lumbar spine functions)

  9. 38 CFR 4.59 Painful Motion With any form of arthritis, painful motion is an important factor of disability. Findings of painful, unstable, or malaligned joints due to healed injury should be entitled to at least the minimum compensable evaluation. (10%)

  10. 38 CFR 4.69 Dominant Hand • Evaluation percentages involving upper extremities will allow for a greater evaluation when the condition affects the major (dominant) hand. • Only one extremity can be dominant. • If the claimant is ambidextrous, the injured hand will be considered dominant.

  11. 38 CFR 4.62 Circulatory Disturbances • Do not overlook circulatory disturbance, especially of the lower extremity following injury in the popliteal space. • Requires rating generally as phlebitis.

  12. Medical Examination Criteria • Examiner must report based on requirements of 38 CFR 4.45 • Additional x-rays, lab work, MRI or CT scans may be ordered • Complete range of motion studies are required • Accurate measurement of the length of any amputation stump is required • Scars and any additional disability due to them should be noted. They are to be rated separately if appropriate.

  13. 38 CFR 4.68 Amputation Rule • The combined evaluation for disabilities of an extremity shall not exceed the rating for the amputation at the elective level, were the amputation to be performed. • Examples

  14. 38 CFR 4.58 Arthritis Due to Strain • When there is a lower extremity shortening or amputation, an associated arthritis that subsequently develops (in lower extremities, lumbosacral joints, or lumbosacral spine) will be service connected.

  15. 38 CFR 4.58 Arthritis Due to Strain • For upper extremities, we can only consider service connection for arthritis in joints subject to direct strain or those actually injured.

  16. Separate Evaluations for Arthritis of the Knee VAOPGCPREC 23-97 General Counsel Opinion held that a claimant who has arthritis and instability of the knee may be rated separately under: DC 5003 (degenerative arthritis) and DC 5257 (knee instability)

  17. Separate Evaluations for Arthritisof the Knee • They determined that 38 CFR 4.14 (pyramiding) only prohibits separate evaluations of disorders having the same disabling manifestations. • A separate rating can be assigned if there is additional disability.

  18. Separate Evaluations for the Knee VAOPGCPREC 9-2004 General Counsel Opining held that a veteran may receive separate ratings for: DC 5260 Limitation of flexion and DC 5261 Limitation of extension for the same knee. (See also FL 04-22)

  19. Separate Evaluationsfor the Knee However, where joint motion is not limited, but there is objective evidence of pain on motion, only one compensable evaluation can be assigned under either DC 5260 or DC 5261. (38 CFR 4.14)

  20. Separate Evaluationsfor the Knee • Although it is permissible to assign multiple evaluations under multiple diagnostic codes for a single knee, always abide by the amputation rule (38 CFR 4.68). • General Counsel Opinions are not a liberalizing interpretation of the rating schedule, and the provisions of 38 CFR 3.114(a) do not apply.

  21. Acute, Subacute, or Chronic Diseases Osteomyelitis (DC 5000) Inflammation of bone matter • Active = infection and antibiotic treatment • Inactive = no recurrence for 5 years • 38 CFR 4.43 – disabling unless removed by amputation • See M21-1MR, III.iv.4.A.7 for rating guidance

  22. Acute, Subacute, or Chronic Diseases Rheumatoid arthritis (DC 5002) • Also called rheumatoid spondylitis, ankylosing spondylitis, or Marie-Strumpell disease • In addition to, or in advance of, x-ray evidence, pay attention to: muscle spasm, soft tissue changes, and constitutional changes

  23. Acute, Subacute, or Chronic Diseases Rheumatoid arthritis – Evaluation Considerations: • Rate as an active process, or • Inactive process based on chronic residuals such as such as LOM or ankylosis under the appropriate DCs for the specific joints involved • Whichever results in the higher evaluation

  24. Acute, Subacute, or Chronic Diseases Degenerative arthritis (DC 5003) • Also known as osteoarthritis or hypertrophic arthritis • Degeneration of joint cartilage or hypertrophy of bone • Need x-ray evidence to diagnose

  25. Acute, Subacute, or Chronic Diseases Degenerative arthritis (DC 5003) continued • If there is limitation of motion, then: • Rate on limitation of motion under the appropriate DC. • Unless this would result in non compensable evaluation, then rate at 10% for each major joint or group of minor joints.

  26. Acute, Subacute, or Chronic Diseases Degenerative arthritis (DC 5003) continued • If there is no LOM, then: • With X-ray evidence of involvement of 2 or more major joints or 2 or more minor joint groups = 10% • With X-ray evidence of involvement of 2 or more major joints or 2 or more minor joint groups, with occasional incapacitating exacerbations = 20% • The 10% and 20% ratings based on X-ray findings, above, will not be combined with ratings based on LOM or for DC 5013-5024.

  27. Arthritis Cases Previously Rated as a Single Disability Re-rate as follows: • If separate evaluation results in no change in combined evaluation, use the new procedure. • If there is an increase in the combined evaluation, use 38 CFR 3.105(a) to retroactively increase the evaluation. • If re-rating causes decrease in combined evaluation, apply 38 CFR 3.105(a) & (e)—unless there is protection under 3.951.

  28. Acute, Subacute, or Chronic Diseases • Other types of arthritis (DC 5004 – 5009) • Traumatic Arthritis (DC 5010) • Need X-ray evidence • Same criteria as DC 5003 • Caisson Disease of Bones (DC 5011) • Malignant New Growths of Bones (DC 5012)

  29. Other Disabilities of Bones and Joints • Osteoporosis (DC 5013) • Osteomalacia (DC 5014) • Benign New Growths of Bones (5015) • Osteitis Deformans (DC 5016) • Gout (DC 5017 – rated under DC 5002, rheumatoid arthritis) • Hydrarthrosis (DC 5018) • Bursitis (DC 5019)

  30. Other Disabilities of Bones and Joints • Synovitis (DC 5020) • Myositis (DC 5021) • Periostitis (DC 5022) • Myositis Ossificans (DC 5023) • Tenosynovitis (DC 5024)

  31. Other Disabilities of Bones and Joints • Fibromyalgia (DC 5025) • Added to Rating Schedule on 5-7-96 • Syndrome characterized by chronic, widespread musculoskeletal pain associated with multiple tender or “trigger” points • Often with multiple somatic complaints, such as sleep disorders, anxiety, fatigue, headache, and irritable bowel symptoms.

  32. Prosthetic Implants • Temporary total evaluation for one year following replacement of: shoulder, elbow, writs, hip, knee, or ankle joint (38 CFR 4.30) • After that, rate on residual disability • DC’s 5051 – 5056 • SMC may be assigned during the period of total evaluation if the permanent use of crutches are required

  33. Anatomical Loss and Loss of Use • X-ray studies may be needed to determine level of amputation • A painful neuroma shall be assigned the evaluation for the elective site of re-amputation

  34. 38 CFR 4.63 Loss of Use of Hand or Foot • For purposes of SMC, loss of use is conceded when the veteran would be equally well served by an amputation with suitable prosthesis • When ordering exams, do not ask about loss of use; rather, ask about remaining function.

  35. 38 CFR 4.64 Loss of Use of Both Buttocks For purposes of SMC, it exists when there is severe damage to muscle group XVII, and when the person cannot, without assistance: Rise from a seated position, or Rise from a stooped position - And maintain postural stability

  36. Combinations of Anatomical Loss and Loss of Use Disabilities DC’s 5104 – 5111: Provide for 100% evaluation based on combinations of disabilities related to anatomical loss or loss of use. Higher SMC may result

  37. Amputations of Upper Extremities DC’s 5120 – 5156: These codes apply to amputations of the upper extremities. Additional entitlement to SMC may result

  38. Finger Disabilities (Last revised August 26, 2002) Fingers are identified as: Thumb (or number 1) Index (or number 2) Long (or number 3) Ring (or number 4) Little (or number 5)

  39. Finger Disabilities Evaluation may be complex because amputation may occur at different levels and with more than one finger. • Refer to Plate III in the Rating Schedule when evaluating fingers. • See directions following DC 5151 in Rating Schedule. • Ensure there is complete evidence of range of motion.

  40. Finger Disabilities DC’s 5126 – 5151: Multiple finger amputations at proximal interphalangeal joint or through the proximal phalange DC’s 5216 – 5219: Multiple finger amputations through long phalanges (rated as unfavorable ankylosis) DC’s 5220 – 5223: Multiple finger amputations at distal joint or through distal phalange (rated as favorable ankylosis) DC’s 5152 – 5156: Single finger amputations

  41. Finger Disabilities • Evaluation of ankylosis or limitation of motion of single or multiple digits of the hand • The Rating Schedule provides range of motion for the fingers which can be found immediately following diagnostic code 5215 • This section also defines favorable and unfavorable ankylosis

  42. Finger Disabilities • DC’s 5216-5219: Multiple finger disability with unfavorable ankylosis • DC’s 5220-5223: Multiple finger disability with favorable ankylosis • DC’s 5224-5227: Individual finger ankylosis • DC’s 5228-5230: Individual finger limitation of motion

  43. Amputations of Lower Extremities DC’s 5160 – 5173: Used to evaluate amputations of lower extremities There may be entitlement to SMC

  44. Evaluating Non-Amputation Disabilities of the Upper Extremities • We must determine which extremity is dominant • Favorable vs. Unfavorable ankylosis • Select the diagnostic code that best describes the level of impairment

  45. Evaluating Non-Amputation Disabilities of the Upper Extremities Shoulder disabilities may be evaluated under: DC 5200 – ankylosis of scapulohumeral articulation, or DC 5201 – limitation of motion of arm Note: Under 5201, limitation of motion can be either shoulder forward elevation plane or the shoulder abduction plane.

  46. DC Upper Extremities, cont. • DC 5202 – Humerus, other impairment of • DC 5203 – Clavicle or scapula, impairment of • DC 5205 – Elbow, ankylosis of • DC 5206 – Forearm, limitation of flexion of; • DC 5207 – Forearm, limitation of extension of;

  47. DC Upper Extremities, cont. • DC 5208 – Forearm, flexion limited to 100 degrees and extension of 45 degrees • DC 5209 – Elbow, other impairment of flail joint • DC 5210 – Radius and ulna, nonunion of, w/ flail false joint • DC 5211 – Ulna, impairment of

  48. Upper Extremities, cont. • DC 5212 – Radius, impairment of • DC 5213 – Supination and pronation, impairment of • DC 5214 – Wrist, ankylosis of • DC 5215 – Wrist, limitation of motion of

  49. Evaluating Non-Amputation Disabilities of the Lower Extremities DC’s 5250 – 5274: used to evaluate disabilities of the hip, thigh, knee and leg Evaluations based on ankylosis, limitation of motion, or weight bearing impairment. Possible SMC with extremely unfavorable ankylosis of the hip

  50. Shortening of the Lower ExtremityDC 5275 When there is a shortening of the bones of the lower extremity, a separate evaluation may be assigned. Do not combine with other evaluations for fracture/faulty union of the same extremity.
