The treatment of a displaced proximal humeral fracture is still a matter of controversy. The purpose of this study was to report outcomes at a long-term follow-up after fixation augmentation using peek (polyether-ether-ketone) cage and locking compression plate (LCP).
A total of 27 patients (average age 53.8 years, range 19-86 years) were treated with peek cage and LCP. All of them had a minimum radiographic and clinical follow-up of 1 years. Outcomes were assessed using the Constant-Murley score (CMS), disability of the arm, shoulder and hand (DASH) score. Complications were also recorded during follow-up.
The average follow-up was 28 months (range 12-48 months). The mean functional outcomes were as follows: CMS, 73.3 (range 61-86); DASH, 45.9 (range 27-68). A total of 4 patients had complications: osteonecrosis developed in one patient, loss of reduction was observed in 1 patient and stiffness was occurred in two patients.
The use of peek cage and LCP has been a valuable option in the treatment of proximal humeral fractures. The complication rate was acceptable. Suitable void filler in the proximal humerus for reconstructing the medial column integrity attains mechanical stability in reducing the incidence of the complications.
肱骨近端移位骨折的治疗仍存在争议。本研究的目的是报告使用聚醚醚酮（PEEK）笼和锁定加压钢板（LCP）进行固定增强后的长期随访结果。
共有27例患者（平均年龄53.8岁，范围19 - 86岁）接受了PEEK笼和LCP治疗。所有患者均进行了至少1年的影像学和临床随访。使用Constant-Murley评分（CMS）、手臂、肩部和手部功能障碍（DASH）评分评估结果。随访期间还记录了并发症情况。
平均随访时间为28个月（范围12 - 48个月）。平均功能结果如下：CMS为73.3（范围61 - 86）；DASH为45.9（范围27 - 68）。共有4例患者出现并发症：1例发生骨坏死，1例出现复位丢失，2例出现僵硬。
使用PEEK笼和LCP是治疗肱骨近端骨折的一种有价值的选择。并发症发生率可以接受。在肱骨近端使用合适的骨缺损填充物重建内侧柱完整性，可在减少并发症发生率方面获得机械稳定性。
