BACKGROUND
Proximal humeral fractures occur frequently. Displaced or unstable fractures require open reduction and internal fixation. Our objective was to investigate the clinical and radiographic results of the internal fixation using Polarus humeral nails for fractures of the proximal humerus.
MATERIALS AND METHODS
From January 2001 to April 2006, 54 shoulders of 54 patients (44 females, 10 males) underwent the intramedullary fixation using Polarus humeral nail. Mean age of the patients was 66-year-old (39-89) at the time of the surgery. Fracture-type by Neer classification was 2-part (29 shoulders), 3-part (22 shoulders) and 4-part (3 shoulders). The clinical and radiological outcomes were evaluated.
RESULTS
All the shoulders after osteosynthesis obtained bone-union. There was no osteonecrosis of the humeral head. Functional outcome measured by JOA score averaged 81 points. Totally 43 patients (79%) had satisfactory to excellent results. Varus deformity was seen in 4 shoulders (8%) and the deformity of the greater tuberosity in 4 (8%).
CONCLUSION
The Polarus intramedullary humeral nail is effective for the treatment of proximal humeral fractures.
背景
肱骨近端骨折较为常见。移位或不稳定骨折需要切开复位内固定。我们的目的是研究使用 Polarus 肱骨钉治疗肱骨近端骨折的临床和影像学结果。
材料与方法
自 2001 年 1 月至 2006 年 4 月，54 例患者（44 例女性，10 例男性）54 侧肩部接受了 Polarus 肱骨钉髓内固定治疗。手术时患者的平均年龄为 66 岁（39-89 岁）。Neer 分型为 2 部分（29 肩）、3 部分（22 肩）和 4 部分（3 肩）。评估了临床和影像学结果。
结果
所有接受内固定的肩部均获得骨愈合。无肱骨头坏死。采用 JOA 评分测量的功能结果平均为 81 分。总共有 43 例（79%）患者获得了满意至优秀的结果。4 例（8%）肩部出现内翻畸形，4 例（8%）大结节变形。
结论
Polarus 髓内肱骨钉对于治疗肱骨近端骨折是有效的。
