摘要:

背景:目前临床上常用的髓外固定方法有髋关节动力螺钉、股骨近端锁定钢板、经皮加压钢板等。髋关节动力螺钉则被认为是治疗股骨转子间骨折的“金标准”,临床应用广泛。
目的:评估髋关节动力螺钉、股骨近端锁定钢板、经皮加压钢板3种不同髓外固定治疗老年股骨转子间骨折的疗效。
方法:选择124例术前可活动的股骨转子间骨折老年患者的临床资料进行回顾性分析,其中53例行髋关节动力螺钉固定,27例股骨近端锁定钢板固定,44例经皮加压钢板固定。根据手术时间、术中失血量、并发症发生率及Sander髋关节创伤评分,比较3组临床疗效。
结果与结论:124例患者中共有96例获得1年以上随访,随访时间12~32个月,平均19.8个月。髋关节动力螺钉、股骨近端锁定钢板、经皮加压钢板3组手术时间分别为 (77.4±7.0),(94.3±12.5),(48.2±9.0) min、术中失血量分别为(220.4±19.3),(237.4±23.9),(86.9±16.9) mL,组间比较差异均具有显著性意义(P < 0.05),3组并发症发生率依次为16.22%,13.04%,5.56%。Sander髋关节创伤评分在三者间差异无显著性意义(P > 0.05)。结果表明,3种不同髓外固定方法均适用于老年股骨转子间骨折,其中经皮加压钢板手术时间短,出血量少,并发症发生率低。

Abstract:

BACKGROUND: Extramedullary fixation methods have been clinically used, such as dynamic hip screw (DHS), proximal femoral locking plate (LCP) and percutaneous compression plate (PCCP). DHS has been considered gold standard for intertrochanteric fractures in elderly people.
OBJECTIVE: To compare the clinical outcomes of DHS, LCP and PCCP in the surgical treatment of intertrochanteric fractures in the elderly.
METHODS: Clinical data of 124 elderly patients with intertrochanteric fractures were retrospectively analyzed, including 53 cases treated with DHS, 27 with LCP, and 44 with PCCP. The outcomes of the three extramedullary fixations were compared by analyzing operation time, blood loss, complication and postoperative Sander hip injury scores.
RESULTS AND CONCLUSION: A total of 96 of 124 cases were followed up with a mean period of 19.8 (range 12-32) months. There were statistically significant differences in the operation time (77.4±7.0, 94.3±12.5, 448.2±9.0) minutes, blood loss (220.4±19.3, 237.4±23.9, 86.9±16.9) mL, among DHS, LCP, and PCCP groups (P < 0.05). However, incidence rate of complication was 16.22% (DHS), 13.04% (LCP), and PCCP (5.56%). There were no significant differences in Sander hip injury score in 3 groups (P > 0.05). Results show that DHS, LCP, and PCCP can be used effectively for the treatment of intertrochanteric fractures. Moreover, PCCP has several advantages, such as shorter operation time, less blood loss and lower complication rate.
