[Purpose]Shoulder disorders caused by multi-directional instability of the shoulder joint are common in the young, but rare in the elderly (over 50 years old). The purpose of this study was to define the clinical features of the elderly cases.[Patients and Clinical Findings]There were 6 cases (over 50years old) with shoulder disorders caused by multi-directional instability of the shoulder.3 males and 3 females were involved. The average age was 58.3 years (range: 50-74).No cuff tears were present in the arthrographies and/or arthroscopies in any of the cases. Two cases had symptoms of cuff tendinitis with a positive impingement sign. The other 4 cases had symptoms and signs of a shoulder contracture on one side. Three of them had severe contractures (frozen shoulders).[Treatment and Results]All the cases with multi-directional instability of the shoulder joint were treated conservatively (muscular strengthening exercises etc.). Two cases with cuff tendinitis, one with mild shoulder contracture and one with a frozen shoulder recovered conservatively. Two cases with a frozen shoulder in the other side were treated with arthroscopic synovectomy and manipulation. After treatment, the range of motion of the shoulder joints improved, but recurred the instability and its symptoms recurred.[Conclusion]The clinical features of elderly cases with multi-directional instability of the shoulder joints were different from those of young cases. Few young cases have symptoms and signs of shoulder contracture, but the elderly have many.
