Figure 2.

Optical presentation of the atrophic muscle in the patient's arm. Panels A-D show different views of the athlete's upper arms. A: lateral view of right upper arm. B: medial view of right upper arm. C: lateral view of left upper arm. D: medial view of left upper arm. Arrows in Panels A and B indicate the hole the athlete remarked on six months after operation. The topographic localization of the hole corresponds to the anatomical structure of the m. brachialis. Arrows in Panels C and D indicate the corresponding region on the healthy arm and show the normal situation without any atrophy.
