Surgical repair of rotator cuff ruptures. The importance of the subacromial bursa

摘要: We examined biopsy specimens obtained during surgery on 115 patients with complete rotator cuff rupture. The vascularised connective tissue covering the area of rupture and proliferating cells in fragmented tendons reflected more features repair than degeneration necrosis. main source this fibrovascular was wall subacromial bursa. These clearly indicated a vigorous reparative response which might play an important role tendon reconstitution remodelling. therefore suggest that extensive debridement along subtotal bursectomy, commonly practised surgical rupture, should be avoided. Although strong suture margins are essential for good operative results, judicious preserve as much possible bursa associated tissue.
