复发性肩关节的前脱位的临床病理表现

Abstract

Objective：To comprehensively know clinical pathological change of recurrent anterior dislocation of shoulder joint by arthroscopy. Materials and Methods 26 patients with recurrent anterior shoulder dislocation were treated in our institute. 24 cases among were divided into two groups, the first group include 16 shoulder dislocated patients accompanied with shoulder hyper-laxity. The other group include 8 purely shoulder dislocated patients. All patients were explored by arthroscopy and all pathological changes were recorded and the difference of pathological changes between the two groups were contrasted. Results：26 cases show anterior-inferior labrum injury, 25 cases show Hill-sachs injury,15 cases show bone or cartilage injury of anterior-inferior glenoid, 14 cases show Slap injury, 5 cases show rotator cuff injury. The pathological changes of the first group were lighter than the other group, include anterior-inferior labrum injury,Hill-sachs injury, bone or cartilage injury of anterior-inferior glenoid. But most cases of rotator cuff injury are showed in the first group. Conclusion：The general pathological changes of recurrent anterior shoulder dislocation are: anterior-inferior labrum injury, Hill-sachs injury, bone or cartilage injury of anterior-inferior glenoid, Slap injury and rotator cuff injury. The pathological changes of shoulder dislocated patients accompanied with shoulder hyper-laxity are lighter than these of purely shoulder dislocated patients.
