下肢肿瘤的手术治疗标准以高度介入技术为特点，导致患者严重的运动障碍和幻痛的发生。旋转成形术已成为患有下肢骨肿瘤的年轻癌症患者的有效保肢治疗选择，但通过比较研究，在引入该手术几年后，其对步态的影响仍不清楚。本研究的目的是与健康个体相比，评估旋转成形术对通过步态分析测量的步态参数的影响。在 2022 年 1 月 10 日之前，系统地检索了 MEDLINE、Scopus 和 Cochrane 数据库中符合条件的研究，没有时间限制。通过步态分析测量的步态参数是感兴趣的结果。三项研究符合分析条件。与健康个体相比，旋转成形术显着降低了步态速度（-1.45 厘米/秒；95% 置信区间 (CI) -1.98 至 -0.93；p < 0.001）、步幅长度（-1.20 厘米；95% CI -2.31 至 -0.09） ；p < 0.001）、步频（-0.83 步幅/分钟；95%（CI -1.29 至 -0.36；p < 0.001）和循环时间非显着增加（0.54 秒；95% CI -0.42 至 1.51；p = 0.184).旋转成形术是治疗年轻癌症患者下肢骨肿瘤的有效选择。需要进行更大规模的研究、高患者应计率、精细的手术技术和精心规划的康复策略，以进一步改善该手术的报告结果.© 2023 作者等人。

The standard of surgical treatment for lower limb neoplasms had been characterized by highly interventional techniques, leading to severe kinetic impairment of the patients and incidences of phantom pain. Rotationplasty had arisen as a potent limb salvage treatment option for young cancer patients with lower limb bone tumours, but its impact on the gait through comparative studies still remains unclear several years after the introduction of the procedure. The aim of this study is to assess the effect of rotationplasty on gait parameters measured by gait analysis compared to healthy individuals.The MEDLINE, Scopus, and Cochrane databases were systematically searched without time restriction until 10 January 2022 for eligible studies. Gait parameters measured by gait analysis were the outcomes of interest.Three studies were eligible for analyses. Compared to healthy individuals, rotationplasty significantly decreased gait velocity (-1.45 cm/sec; 95% confidence interval (CI) -1.98 to -0.93; p < 0.001), stride length (-1.20 cm; 95% CI -2.31 to -0.09; p < 0.001), cadence (-0.83 stride/min; 95% (CI -1.29 to -0.36; p < 0.001), and non-significantly increased cycle time (0.54 sec; 95% CI -0.42 to 1.51; p = 0.184).Rotationplasty is a valid option for the management of lower limb bone tumours in young cancer patients. Larger studies, with high patient accrual, refined surgical techniques, and well planned rehabilitation strategies, are required to further improve the reported outcomes of this procedure.© 2023 Author(s) et al.
