In the case of a 19-year-old man, overuse of his nondominant forearm resulted in a radioulnar synostosis. Despite the persistence of the synostosis, the patient adapted to loss of forearm rotation. No further treatment was necessary. Isolated fractures of the ulnar shaft are slow in healing. Several authors observed that early function may be beneficial. However, excessive activity causing motion at the fracture site may cause subperiosteal hemorrhage and soft tissue trauma and may stimulate exuberant callus formation. Fractures of the ulnar shaft, even undisplaced, need to be immobilized to prevent overuse.
对于一名19岁男性，其非优势前臂过度使用导致了桡尺骨融合。尽管融合持续存在，但患者适应了前臂旋转功能的丧失，无需进一步治疗。尺骨干孤立性骨折愈合缓慢。几位作者观察到早期功能锻炼可能有益。然而，导致骨折部位活动的过度活动可能会引起骨膜下出血和软组织创伤，并可能刺激形成过度的骨痂。尺骨干骨折，即使没有移位，也需要固定以防止过度使用。
