Muscle Disabilities Gunshot & Shrapnel Wounds
For VA rating purposes, the cardinal signs and symptoms of muscle disability are loss of power, weakness, lowered threshold of fatigue, fatigue-pain, impairment of coordination and uncertainty of movement. Disabilities resulting from muscle injuries shall be classified as slight, moderate, moderately severe or severe as follows:
Slight Disability of Muscle
Simple wound of muscle without debridement or infection. Minimal scar. No evidence of fascial defect, atrophy, or impaired tonus. No impairment of function or metallic fragments retained in muscle tisue
Moderate Disability of Muscle
Through and through or deep penetrating wound of short track from a single bullet, small shell or shrapnel fragment, without explosive effect of high velocity missile, residuals of debridement, or prolonged infection. Entrance and (if present) exit scars, small or linear, indicating short track of missile through muscle tissue. Some loss of deep fascia or muscle substance or impairment of muscle tonus an dloss of power or lowered threshold of fatigue when compared to the sound side.
Moderately Severe Disability of Muscle
Through and through or deep penetrating wound by small high velocity missile or large low-velocity missile, with debridement, prolonged infection, or sloughing of soft parts, and intermuscular scarring. Entrance and (if present) exit scars indicating track of missile through one or more muscle groups. Indications on palpation of loss of deep fascia, muscle substance, or normal firm resistance of muscles compared with sound side. Tests of strenght and endurance compared with sound side demonstrate positive evidence of impairment.
Severe Disability of Muscle
Through and through or deep penetrating wound due to high velocity missile, or large or multiple low velocity missiles, or with shattering bone fracture or open comminuted fracture with extensive debridement, prolonged infection, or sloughing of soft parts, intermuscular binding and scarring. Ragged, depressed and adherent scars indicating wide damage to muscle groups in missile track. Palpation shows loss of deep fascia or muscle substance, or soft flabby muscles in wound area. Muscles swell and harden abnormally in contraction. Tests of strenghth, endurance, or coordinated movements compared with the corresponding muscles of the uninjured side indicate severe impairment of function.
