摘　　要：背景：有研究表明股骨颈骨折内固定后骨折不愈合、股骨头坏死率及翻修率较高。目的：观察新型内固定物经皮加压钢板修复股骨颈骨折的安全性及近期疗效。方法：采用经皮加压钢板治疗新鲜股骨颈骨折患者24例,记录每例患者的植入后3d疼痛评分、末次随访髋关节功能评分、骨折愈合情况及并发症的发生情况。结果与结论：随访时间平均6.2个月（2.5~11个月）,其中14例患者随访时间超过半年,骨折已愈合。未发现内固定断裂、再骨折、髋内翻等早期并发症。所有患者植入时、植入后均未输血。平均部分负重时间4.8d（2~14d）。植入后3d疼痛口述分级评分法评测结果显示：1级10例,2级12例,3级2例,1级和2级占91%。末次随访髋关节功能评分优良率为87%。结果证实,植入经皮加压钢板修复股骨颈骨折是安全的;坚强的内固定支持可以满足患者早期扶拐负重行走。BACKGROUND：Meta-analysis shows the high rate of nonunion,femoral head necrosis and operative revision in femooal neck fractures after internal fixation.OBJECTIVE：To explore the security and short-term therapeutic effect of novel implant percutaneous compression plate（PCCP） on the recovery of femoral neck fractures.METHODS：Twenty-four patients suffering from fresh femoral neck fractures were treated with PCCP.The postoperative pain score at 3 days,a Harris score of the last follow-up,union of fracture and complications were recorded.RESULTS AND CONCLUSION：The mean duration of follow-up was 6.2 months（2.5-11 months）.There were 14 cases followed-up for more than half a year and all of them were healed.No fixation failure,re-fracture,hip varus or other complications were found.There was no blood transfusion preformed in any patient during and after operation.The mean time of partial weight-bearing was 4.8 days（2-14 days）.Postoperative pain rank at 3 days showed：grade one in 10 cases,grade two in 12 cases and grade three in two cases.Cases in grade one and two accounted for 91%.According to Harris score,the postoperative excellent rate reached 87% after the final follow-up.It shows that the novel implant PCCP implantation is security to the recovery of femoral neck fractures.Stable fixation allows patients early weight-bearing rehabilitation which makes satisfactory short-term therapeutic outcomes.
