单纯空心螺钉微创内固定治疗对髌骨横形骨折患者术后恢复的影响

Effects of minimally invasive internal fixation by cannulated compression screws on the postoperative recovery of patients with patellar transverse fracture

目的探讨单纯空心螺钉微创内固定对髌骨横形骨折患者术后恢复的影响。方法选择我院2012年3月~2017年5月收治的74例髌骨横形骨折患者为研究对象,以随机数字表法分为对照组与观察组,各37例,对照组患者接受克氏针张力带内固定,观察组接受C型臂X线机辅助下微创空心钉内固定,对两组膝关节功能恢复情况及术后并发症发生率进行比较。结果术后随访6月,观察组膝关节功能恢复优良率为91.89%,高于对照组的72.97%(P<0.05);观察组术后感染、切合延迟愈合、固定物松动等并发症发生率低于对照组(P<0.05)。结论微创空心钉内固定治疗髌骨横形骨折疗效确切,相比较切开复位克氏针张力带内固定并发症发生率低,切口小,患者接受度高,值得推广。

Objective To investigate the effect of minimally invasive internal fixation by cannulated compression screws on the postoperative recovery of patients with patellar transverse fracture. Methods 74 cases with patellar transverse fracture admitted to our hospital from March 2012 to May 2017 were included and divided into control group and observation group by random number table method, with 37 cases in each group. The control group received K-wire tension band internal fixation, while the observation group received minimally invasive internal fixation by cannulated compression screws assisted by C arm X-ray machine. The recovery condition of knee function and incidence rate of postoperative complications in both groups were compared.Result The postoperative follow-up of six months revealed that the fineness rate of functional recovery of knees of observation group was 91.89%, which was significantly higher than that of control group（72.97%, P〈0.05）; the incidence rate of postoperative complications, such as postoperative infection, delayed incision healing and fixation loosening,of observation group was significantly lower than that of control group（P〈0.05）.Conclusion The application of minimally invasive internal fixation by cannulated compression screws in the treatment of patients with patellar transverse fracture has obvious curative effect and enjoys higher patient acceptance rate than K-wire tension band internal fixation for its lower incidence rate of postoperative complications and smaller incision, thus worthy of clinical application and promotion.
