Proximal radioulnar synostosis is a rare but highly disabling posttraumatic complication in periarticular elbow injuries. Surgical treatment is an option for functionally limiting proximal radioulnar synostosis; however, the approach can endanger local neurovascular structures, especially if the synostosis affects the level of the bicipital tuberosity. We report two cases of proximal radioulnar synostosis with a preoperative prono-supination range of motion of 0° and 15° treated by a reverse Sauvé-Kapandji procedure resecting a 1-cm section of the radial shaft distal to the bicipital tuberosity and leaving the synostosis in place. An improvement in prono-supination arc of motion of 82.5° was achieved at 2 years of follow-up with no complications associated with the technique. The reverse Sauvé-Kapandji procedure could be an option in the treatment of proximal radioulnar synostosis in selected cases.
近端桡尺关节融合是一种罕见但严重致残的肘关节周围创伤后并发症。手术治疗是一种针对功能受限的近端桡尺关节融合的选择；然而，该手术方法可能危及局部神经血管结构，特别是当融合影响肱二头肌结节水平时。我们报告了两例近端桡尺关节融合病例，术前旋前-旋后活动范围分别为0°和15°，采用改良Sauvé-Kapandji手术治疗，切除肱二头肌结节远端1厘米的桡骨干段，保留融合部位。随访2年时，旋前-旋后活动弧度改善了82.5°，且该技术无相关并发症。改良Sauvé-Kapandji手术在某些特定病例中可能是治疗近端桡尺关节融合的一种选择。
