Thương tích là sự gián đoạn nghiêm trọng của xương cườm tay Perilunate sự, nào là một thách thức lớn đối với các bác sĩ Điều trị. Chính xác công nhận mô hình của thương KHÔNG Luôn luôn đơn giản. Có thể tuyên truyền thông qua các chấn thương dây chằng và / hoặc xương, | Perilunate Injuries Diagnosis and Treatment Scott H. Kozin MD Abstract Perilunate injuries are severe disruptions of the carpus which present a formidable challenge to the treating physician. Accurate recognition of the pattern of injury is not always straightforward. The injury can propagate through ligaments and or bone creating multiple variations of a basic injury pattern. Posteroanterior and lateral radiographs will depict a perilunate injury but additional views may be necessary to appreciate subtle carpal fractures. Once the diagnosis has been established early intervention is necessary for optimal results. An initial closed reduction with sedation and traction is performed to restore overall carpal alignment. However subsequent closed or open reduction is necessary to restore anatomic alignment of all injured structures. The outcome of perilunate injuries correlates with the adequacy of reduction. Complications such as chondrolysis carpal instability and traumatic arthritis can occur despite satisfactory treatment. J Am Acad Orthop Surg 1998 6 114-120 Perilunate injuries are severe carpal disruptions. Unfortunately such injuries are frequently missed. The natural history of untreated injuries is progressive traumatic arthritis with pain and Early accurate diagnosis is necessary to initiate appropriate intervention. To achieve the optimal outcome carpal alignment must be accurately restored. Delayed treatment has been shown in several reports to significantly compromise the 2 This article will review carpal anatomy kinematics and pathomechanics as well as diagnostic techniques and treatment options. Anatomy and Kinematics The carpal bones are tightly linked by a combination of capsular and interosseous The cap sular ligaments originate from the radius and insert on the carpus. The interosseous ligaments traverse the carpal bones. The lunate is the keystone of the carpus and acts as the intercalated segment. The lunate is .
