抄録

In order to evaluate the residual disabilities caused by chronic acromioclavicular (A-C) dislocations,14 Judo athletes (7 cases of Grade II and 7 cases of Grade III) injuries were reviewed. Clinical examinations and isokinetic muscle strength of internal/external rotation and of flexion/extension in the supine position were examined. In Grade II, there were no clinical symptoms or differences in isokinetic muscle strength between the involved and uninvolved sides.<BR>In Grade III,4 cases had motion pain and 3 cases felt weakness in Judo practice. In Grade III the A-C joints, the directions of instability were horizontal as well as vertical. Work magnitudes of extension (60 deg/sec) and those of external rotation at 30° abduction (60 and 120 deg/sec)were less in the involved side than those in the uninvolved sides. Isokinetic muscle strength of extension and external rotation at 30° abduction (60 deg/sec) in Grade III was smaller than that in Grade II. Characteristically, the involved side of Grade III cases had less power than the uninvolved side in flexion/extension above the horizontal level. In Grade III, the torn A-C capsular and coracoclavicular ligaments produce more unstable A-C joints than in Grade II.<BR>During an arm elevation above the horizontal level, more than 3/4 of a clavicle rotation occurs and is controlled by the trapezoid ligament. Unstable A-C joint causes an unstable scapula, leading to muscle weakness of the shoulder, especially in flexion/extension above the horizontal level. The current study showed that the Grade III had patterns in the flexion/extension which were different in the involved and uninvolved sides.<BR>This could explain why there is weakness above the horizontal level in Grade III injuries. Therefore, an operation is recommended for Grade III A-C injuries of Judo athletes.
