The therapeutic algorithm for the treatment of Mason type II radial head fractures is still controversially discussed. This study describes the technique of percutaneous fracture reduction without additional internal fixation of the radial head as an alternative to open reduction and presents the results of the method.
The data from 26 out of 30 patients with a Mason type II radial head fracture who had been consecutively treated with percutaneous fracture reduction were evaluated retrospectively. The analysis comprised the disabilities of shoulder and hand (DASH) score, the Mayo elbow performance score (MEPS) and data from the radiological examinations.
The average follow-up time was 21 months (range 6-47 months). In 22 cases (85 %) an anatomical reduction could be achieved, 2 cases (8 %) showed a complete redislocation of the fragment and 2 cases (8 %) a partial redislocation. The average DASH score was 5.6 points (range 0-56) and the average MEPS was 93.8 (range 60-100). Only 4 patients (15 %) reported persisting functional impairment with a DASH score >10.
The method of percutaneous reduction of radial head fractures without additional internal fixation in Mason type II fractures has been demonstrated to be a good alternative to open reduction.
Mason II型桡骨头骨折的治疗算法仍存在争议。本研究描述了一种桡骨头经皮骨折复位且不附加内固定的技术，作为切开复位的替代方法，并展示了该方法的结果。
回顾性评估连续接受经皮骨折复位治疗的30例Mason II型桡骨头骨折患者中26例的数据。分析包括肩手功能障碍（DASH）评分、梅奥肘关节功能评分（MEPS）以及影像学检查数据。
平均随访时间为21个月（范围6 - 47个月）。22例（85%）实现了解剖复位，2例（8%）出现骨折块完全再脱位，2例（8%）出现部分再脱位。平均DASH评分为5.6分（范围0 - 56），平均MEPS为93.8（范围60 - 100）。只有4例患者（15%）报告DASH评分>10且存在持续功能障碍。
对于Mason II型骨折，桡骨头经皮复位且不附加内固定的方法已被证明是切开复位的良好替代方法。
