可吸收螺钉与金属螺钉治疗中重度拇外翻的临床应用效果

Comparative Study of Clinical Value of Absorbable Screws and Metal Screw in the Treatment of Patients with Moderate to Severe Hallux Valgus

目的:探讨可吸收螺钉与金属螺钉治疗中重度拇外翻的临床应用效果。方法:选取2016年1月至2018年1月我院收治的28例中重度拇外翻患者作为研究对象,按照随机数字表法分为2组,分别采用金属螺钉或可吸收螺钉治疗对照组和观察组拇外翻患者。比较两组患者围手术期指标,手术前后拇外翻角(HVA),第1、2跖骨间夹角(IMA),美国矫形足踝学会足功能评分(AOFAS),以及并发症发生情况。结果:两组患者手术时间、术中出血量、住院时间比较无统计学差异(P>0.05)。两组患者术后HVA、IMA、AOFAS均优于术前,比较具有统计学差异(P<0.05);两组患者术后HVA、IMA、AOFAS比较无统计学差异(P>0.05)。对照组治疗优良率为88.46%,观察组治疗优良率为92.31%,两组间无统计学差异(P>0.05)。两组患者截骨端延迟愈合或不愈合发生率比较无统计学差异(P>0.05);两组患者切口感染、拇外翻复发或者术后丢失矫正度数、跖骨发生背侧移位、出现转移性跖痛、拇内翻发生率比较无统计学差异(P>0.05)。结论:拇外翻截骨后采用可吸收螺钉固定,可提供稳定固定,治疗效果显著,不增加并发症发生风险,值得广泛应用于临床。

Objective: To explore the clinical application of absorbable screws and metal screw in the treatment of patients with moderate to severe hallux valgus. Methods: From January 2016 to January 2018, 28 patients with moderate to severe hallux valgus admitted to our hospital were enrolled in the study. They were divided into 2 groups according to the random number table method. The control group and the observation group were treated with metal screws or absorbable screws. Patients with hallux valgus. Absorbing screws treat hallux valgus. Perioperative indicators were compared between the two groups, the hallux valgus angle(HVA) before and after surgery, the angle between the first and second metatarsal, the American Society of Orthopedic Foot and Foot Function(AOFAS), and complications. Results: There was no significant difference in operation time, intraoperative blood loss, and hospital stay between the two groups(P>0.05). The HVA, IMA and AOFAS were better than those before operation(P<0.05). There was no significant difference in HVA, IMA and AOFAS between the two groups(P>0.05). The excellent and good rate of treatment in the control group was 88.46%, and the excellent and good rate in the observation group was 92.31%. There was no significant difference in the excellent and good rate between the two groups(P>0.05). The incidence of delayed healing or non-union, hallux valgus recurrence or postoperative loss correction in the observation group was lower than that in the control group(P<0.05). Incision infection and tibia lateral displacement occurred in the two groups. There was no significant difference in the incidence of metastatic pain and hallux valgus(P>0.05). Conclusion: After the hallux valgus osteotomy, it can be fixed by absorbable screws, the treatment effect is remarkable, and the safety is high, which is worthy of being widely used in clinical practice.
