Abstract：
UNASSIGNED: Radioulnar synostosis is an uncommon complication of forearm fractures and presents with varying degrees of restricted forearm movement. The diaphysial distal third synostosis is less common and excision of the synostosis is fraught with risk of re-ossification. Use of inert or biological interposing material has thus been accompanied with the synostosis excision and various methods have been described. There is still no consensus on the ideal treatment method.
UNASSIGNED: We, hereby, report a case of a long-standing radioulnar synostosis with rotational restriction of movement. Despite the movement restriction, the patient could perform basic activities of daily living and wanted to improve the movements. The presence of diaphyseal radioulnar synostosis was conformed on the radiographs and computerized tomography scan. A volar forearm approach was used and the bony bridge was excised. The ipsilateral native palmaris longus (PL) tendon was extracted from distal wrist crease and with its proximal attachment intact, circumferentially wrapped around the ulnar raw surface as an interposing material. Apart from this, free fat was also placed at the synostosis site. In the long-term follow-up of 10 years, there was no radiological evidence of re-ossification noted. The clinical improvement was not much but the patient was performing activities of daily living with no discomfort.
UNASSIGNED: The use of an encircling loop of the native PL tendon, over the raw surface of one of the forearm bones, may be another useful method to decrease the chances of recurrence following the excision of the synostosis.

摘要：
■桡骨滑脱症是前臂骨折的罕见并发症，并表现出不同程度的前臂运动受限。骨干远端第三骨性骨膜不太常见，切除骨膜有再次骨化的风险。因此,惰性或生物插入材料的使用已经伴随着滑膜切除,并且已经描述了各种方法。对于理想的治疗方法仍未达成共识。
■我们，特此,报告一例长期伴有旋转运动限制的尺桡骨滑膜。尽管行动受到限制，患者可以进行日常生活的基本活动，并希望改善运动。X线照片和计算机断层扫描上都符合骨干radi的存在。使用掌侧前臂入路并切除骨桥。同侧天然掌长（PL）肌腱从远端腕部折痕中拔出，近端连接完整，周向缠绕尺骨原始表面作为插入材料。除此之外,游离脂肪也放置在滑膜部位。在10年的长期随访中，没有发现骨化的放射学证据.临床改善不大，但患者正在进行日常生活活动，没有不适。
■使用自体PL肌腱的环绕环，在前臂骨之一的原始表面上，可能是另一种有用的方法，以减少复发的机会后，切除的滑膜。
