Các biến chứng của phẫu thuật cho sự bất ổn định glenohumeral là tương đối hiếm. Khi chúng xảy ra, tận dụng thất bại và có một doanh ổn định có thể là những thách thức tuyệt vời. Công nhận chính xác nguyên nhân của sự bất ổn và áp dụng các kỹ thuật phẫu thuật thích hợp là rất quan trọng. | Complications of Open Anterior Stabilization of the Shoulder Mark D. Lazarus MD and Douglas T. Harryman II MD Abstract Complications of surgery for glenohumeral instability are relatively uncommon. When they occur salvaging failures and obtaining a stable joint can be awesome challenges. Accurate recognition of the cause of the instability and application of the appropriate surgical technique are critical. Deficiencies of the glenoid concavity the anterior capsule or the subscapularis may be present and require correction. Overtightening a shoulder and eliminating its normal laxity should be avoided. Loose or malpositioned hardware about the glenohumeral joint must be recognized as soon as possible and removed. The goal of treatment is to correct the deficient stabilizing mechanisms without altering normal glenohumeral function. J Am Acad Orthop Surg 2000 8 122-132 The results of primary surgical repair for glenohumeral instability are reasonably predictable and can be gratifying for both patient and surgeon. Patients disabled by recurrent shoulder instability often return to full function within months after repair. When surgery is unsuccessful however the situation can be among the most difficult to salvage. There are several common causes of failure after open instability surgery and understanding how these problems arise allows the surgeon to develop methods to avoid complications and techniques to deal with them. Recurrence of Instability The most frequently reported complication after open surgery for anterior instability is recurrent Matsen et al9 have defined instability as the inability to keep the humeral head perfectly centered within the glenoid fossa. This definition was accepted at a special symposium of the American Academy of Orthopaedic Depending on the specific surgical technique performed reported rates of recurrence of instability range from 3 to 50 .3 A wide variety of factors can account for persistent instability
