To assess the clinical effects of artificial radial head prosthesis replacement for the treatment of comminuted fracture of the radial head.
From June 2011 to June 2015, 25 patients with radial head comminuted fracture were treated with artificial radial head replacement, including 10 males and 15 females, ranging in age form 24 to 61 years old(mean, 40 years old). The functional recovery of the patients suffering from limb and elbow in different periods, the activity degree of the elbow joint and the function of the elbow in the latest follow-up were compared.
All the patients were followed up, and the duration ranged from 12 to 48 months, averaged 26 months. There were no complications such as infection, elbow instability, subluxation of the distal radioulnar joint, and myositis ossificans. The VAS, Broberg and Morrey elbow function score were improved 6, 9 months after operation compared with that 3 months after operation(<0.05). There were significant differences in elbow flexion and extension, rotation activity between injured side and healthy side 3, 6, 9 months after operation(<0.01), but no significant differences between injured side and healthy side at the latest follow-up(>0.05). At the latest follow-up, according to Broberg and Morrey elbow function evaluation criteria, 16 cases got an excellent result, 7 good and 2 poor.
It can maximize the recovery of elbow joint stability and quicken early functional exercise, prevent and reduce the occurrence of complications by using the artificial radial head replacement therapy to repair comminuted fracture of the radial head. The short-term curative effect is satisfactory, but the long-term effect needs further observation.
评估人工桡骨头假体置换治疗桡骨头粉碎性骨折的临床效果。
2011年6月至2015年6月，对25例桡骨头粉碎性骨折患者行人工桡骨头置换术，其中男性10例，女性15例，年龄24～61岁，平均40岁。比较患者不同时期肢体及肘关节功能恢复情况、肘关节活动度及末次随访时肘关节功能。
所有患者均获随访，随访时间12～48个月，平均26个月。无感染、肘关节不稳、下尺桡关节半脱位及骨化性肌炎等并发症。术后6、9个月视觉模拟评分（VAS）、Broberg和Morrey肘关节功能评分较术后3个月改善（<0.05）。术后3、6、9个月伤侧与健侧肘关节屈伸、旋转活动度比较差异有统计学意义（<0.01），末次随访时伤侧与健侧比较差异无统计学意义（>0.05）。末次随访时，根据Broberg和Morrey肘关节功能评价标准，优16例，良7例，差2例。
采用人工桡骨头置换术修复桡骨头粉碎性骨折，可最大限度恢复肘关节稳定性，加快早期功能锻炼，预防和减少并发症发生。近期疗效满意，但远期效果有待进一步观察。
