Injury to muscles that rotate the thigh outward.
Because the rating levels are defined by the criteria in § 4.56, your medical records should reflect what that section measures. Records showing the size and nature of the wound or injury, imaging or surgical findings describing muscle damage, and physical examination findings documenting weakness or limited outward rotation of the thigh are directly relevant. Strength testing of the hip rotators and documentation of any muscle wasting or scarring helps place the injury at a specific level of severity. Statements from you or people who know you describing how hip instability or weakness affects your ability to walk, stand, climb, or carry out daily tasks can also bear on where the injury falls on the scale from slight to severe. If your injury has affected the use of your entire leg, that finding should be clearly documented, as it may be relevant to the special monthly compensation provision.
