Background

It remains unclear whether to perform a bone graft is necessary during posterior arthroscopic subtalar arthrodesis. The present research aimed to comparatively analyze the outcomes of arthroscopic subtalar arthrodesis through a 3-portal posterior approach with or without bone graft.

Methods

A total of 93 patients with subtalar arthritis who underwent posterior arthroscopic subtalar arthrodesis were retrospectively examined. The patients were divided into two groups according to whether they received bone graft or not. The clinical outcomes were compared for analysis.

Results

Among the 93 patients included, 53 received bone graft and 40 did not. The union rate and time to osseous fusion suggested no significant difference between the two groups. The improvement of clinical outcomes were comparable between the two groups at the final follow-up.

Conclusions

In the present study, bone graft could not effectively reduce the risk of nonunion and improve the outcome.

后路关节镜下距下关节固定术联合或不联合植骨治疗距下关节炎的疗效比较

背景

目前尚不清楚后路关节镜下距下关节融合术是否需要植骨。本研究旨在比较分析采用或不采用植骨的三孔后入路关节镜下距下关节固定术的疗效。

方法

对 93 例行后路关节镜距下关节融合术的距下关节炎患者进行了回顾性研究。根据是否接受植骨将患者分为两组。比较临床结果进行分析。

结果

在纳入的 93 名患者中，53 名接受了骨移植，40 名未接受骨移植。愈合率和骨融合时间表明两组之间没有显着差异。在最后一次随访时，两组之间临床结果的改善具有可比性。

结论

在本研究中，骨移植不能有效降低骨不连的风险并改善结果。
