Shoulder pain is the most common problem in sports which require throwing motion. The causes of shoulder pain are resulted to tendinitis, bursitis, recurrent anterior dislocation and impingement syndrome in many cases. During a 15-Year period, from 1960 through 1985, we encounterd 8 patients with axillary nerve palsy according to throwing motion. The average age of these patients was 17years (range 13 to 20 years). All were students participating in a sports (Baseball: 2, Volleyball: 2, Table tennis: 1, Basketball: 1, Tennis: 1, Badminton: 1). Symptoms began with onset of pain and paresthesia around the shoulder without trauma in all patients. The point tenderness was always found posterioly in the quadrilateral space. Many patients had a normal range of motion of the shoulder. Sensory disturbance of the axillary innervated area and motorloss of deltoid muscle was minimun in all patients. Length of free from shoulder pain ranged from 2 weeks to 6 months with an average length of 2.7 months. Electromyographies were performed on five patients. The deltoid was observed for reduced interference patterns and polyphasic potentials. The surface electromyograms during throwing motion were recorded from the muscles around the shoulder. The contraction of teres major and the long head of the triceps was observed during acceleration to the beginning of follow through phase. We suspected the causes of axillary nerve palsy according to throwing motion were considered following: the shoulder in abduction, extention, external rotation during wind up phase causes stretching and entrapment of axillary nerve in quadrilateral space and in abduction, flexion, internal rotation during acceleration phase causes further entrapment by contraction of teres major and the long head of the triceps. This report indicate that a player who require throwing motion could sustain a injury to axillary nerve and this injury is not so rare and has been neglected.

本研究は,前腕の固定角度による日常生活動作の難易度を明確にするため,健常成人24名を対象に前腕の肢位を固定し4種目の日常生活動作の難易度を自己評定させた。測定は前腕を回内60度,30度,中間位,回外30度,60度,90度の計6肢位とし,各々の固定角度にて書字動作,食事動作,洗面動作,トイレ動作を行った。さらに,その時の肘関節の影響についても調査した。結果,書字動作は回内位主体の動作であり回内30度が動作容易であった。他の3動作は,回外位主体の動作であり回外30度,回外60度が動作容易であった。4動作間の肘関節運動は異なるが,各動作の前腕回旋固定角度による肘関節運動への影響は,認められなかった。
