摘要:

文题释义:
股骨颈动力交叉钉系统:是AO最新设计的一种适用于股骨颈骨折的内固定系统,由ARS螺钉、螺栓和板3个部分组成,是一种新型微创植入物,3个部分共同构成一个统一整体,通过锁定机制动态固定股骨颈系统,具有优良的生物力学性能,可为骨折部位提供更加有效的加压和更大的机械稳定性,是目前最具有应用前景的股骨颈骨折固定方式。
富血小板血浆:为组织修复的一项前沿技术,是目前临床研究和应用的热点。是通过采集自体全血、经专业人员无菌高速离心操作后获得的血小板浓缩物,其成分主要是浓度极高的血小板、白细胞和纤维蛋白。血小板活化时产生和释放丰富的生长因子和细胞因子,可以影响炎症、术后失血、感染、成骨、创伤、肌肉撕裂和软组织愈合,其在骨科、运动医学等领域得到广泛应用,并且在其他学科也得到广泛的重视。

背景:对于青壮年的股骨颈骨折患者,治疗目的首要是尽早实现解剖复位固定,促进骨折愈合。目前研究表明,股骨颈骨折后骨不连的发生率为10%-30%,而股骨头坏死的发生率高达15%-30%,这对于患者预后来讲面临着巨大的风险。
目的:研究富血小板血浆联合股骨颈动力交叉钉系统治疗年轻股骨颈骨折的临床疗效。
方法:纳入2020年1月至2021年1月在南京医科大学第二附属医院接受治疗的52例股骨颈骨折患者临床资料,年龄18-55岁。其中18例常规行闭合复位3枚空心螺钉内固定治疗(A组),18例行闭合复位股骨颈动力交叉钉系统内固定治疗(B组),16例行闭合复位股骨颈动力交叉钉系统内固定联合富血小板血浆治疗(C组)。术后采用股骨颈正侧位X射线片来评估骨折复位的质量,采用Fernandez-Esteve骨痂评分评定术后6个月、1年骨折愈合情况,采用髋关节Harris评分评定术后6个月、1年的髋关节功能,同时比较分析股骨头短缩的发生率。
结果与结论:①52例患者均顺利完成手术,未出现感染、再骨折、下肢深静脉血栓等并发症,术后获得至少1年的随访;②术后骨折愈合时间C组优于A、B组(P < 0.05);术后6个月、1年时髋关节Harris评分C组高于A、B组(P < 0.05);术后6个月Fernandez-Esteve骨痂评分C组高于A、B组(P < 0.05);术后C组股骨头短缩发生率低于A组(P < 0.05);③提示应用股骨颈动力交叉钉系统联合富血小板血浆治疗年轻患者的股骨颈骨折,有助于提高治疗效果,促进骨折愈合,降低股骨头短缩的发生,改善患者预后。

Abstract: BACKGROUND: For young patients with femoral neck fracture, the primary purpose of treatment is to achieve anatomical reduction and fixation to promote fracture healing. However, current studies have shown that after the occurrence of femoral neck fracture, the incidence of nonunion was 10%-30%; the incidence of femoral head necrosis was 15%-30%. Therefore, the risk to these patients is substantial.  
OBJECTIVE: To study the clinical efficacy of platelet-rich plasma combined with femoral neck system in the treatment of femoral neck fracture in young patients.
METHODS:  The clinical data of 52 patients (aged 18-55 years) with femoral neck fracture treated in Second Affiliated Hospital of Nanjing Medical University from January 2020 to January 2021 were included. Among them, 18 patients were treated with closed reduction and internal fixation with three cannulated screws (group A); 18 patients were treated with closed reduction and femoral neck system internal fixation (group B); 16 patients were treated with closed reduction and femoral neck system internal fixation combined with platelet-rich plasma (group C). The quality of fracture reduction was evaluated by anterior and lateral X-ray of femoral neck. Fracture healing at 6 months and 1 year after operation was evaluated by Fernandez-Esteve callus score. Hip joint function at 6 months and 1 year after operation was evaluated by Harris hip score. The incidence of femoral neck shortening was compared and analyzed between the two groups.  
RESULTS AND CONCLUSION: (1) All the 52 cases completed the operation successfully and no complications such as infection, re-fracture, or deep venous thrombosis of lower extremities occurred. They were followed up for at least one year. (2) The postoperative fracture healing in group C was better than that in groups A and B (P < 0.05). Harris hip score in group C was higher than that in groups A and B at 6 months and 1 year after operation (P < 0.05). At 6 months after operation, the Fernandez-Esteve callus score in group C was higher than that in groups A and B (P < 0.05). The incidence of femoral neck shortening in group C was lower than that in group A after operation (P < 0.05). (3) The surgical treatment of femoral neck fracture with femoral neck system combined with platelet-rich plasma is helpful to improve the therapeutic effect, promote fracture healing, reduce the occurrence of femoral neck shortening and improve the prognosis of patients.
