Abstract：
In the forearm, posttraumatic heterotopic ossification usually forms as a proximal radioulnar synostosis. It can occur after soft tissue injury involving the interosseous membrane or after surgery involving the radio and ulna, such as distal biceps tendon repair. It can also be induced by radial head dislocation or fracture. Screening radiography can be used to select the appropriate time for excision. The synostosis can be resected when the ectopic bone margin and trabeculation appear mature on radiographs. An interval of 6-12 months from the injury is generally recommended based on ectopic bone maturity. Selection of the surgical approach depends on site, extension (elbow joint or proximal radioulnar joint), severity of the initial articular surface, and periarticular tissue injury. The posterolateral approach is indicated for synostoses: at or distal to the bicipital tuberosity, at the level of the radial head, and proximal radioulnar joint. The posterior global approach is recommended when the forearm synostosis is associated with complete bony ankylosis of the elbow involving the distal aspect of the humerus. After surgical resection of a proximal radioulnar synostosis, the exposed bone surfaces can be covered with interposition material to minimize recurrence.
摘要：
在前臂，创伤后异位骨化通常形成为近端尺桡骨滑膜。它可以发生在涉及骨间膜的软组织损伤或涉及放射和尺骨的手术后，像肱二头肌远端肌腱修复。也可由桡骨头脱位或骨折引起。筛选射线照相术可用于选择合适的切除时间。当X线片上异位骨缘和小梁成熟时，可以切除骨膜。通常根据异位骨成熟度，建议从损伤开始间隔6-12个月。手术方法的选择取决于：部位，延伸(肘关节或尺尺尺关节，初始关节表面和关节周围组织损伤的严重程度。后外侧入路适用于滑膜：在二头肌结节处或远端，在radial头和近端径向关节的水平。当前臂滑膜与涉及肱骨远端的肘关节完全骨性强直有关时，建议采用后路整体入路。经手术切除近端尺桡骨滑膜后，暴露的骨表面可以用插入材料覆盖以最小化复发。
