The goal of this study was to perform a functional (subjective) and radiological evaluation of patients who had undergone forearm lengthening by distraction osteogenesis years before.
Eleven patients with forearm shortening of various etiology were enrolled. They had undergone a total of 21 lengthening procedures. A retrospective analysis of radiological data was conducted and a subjective evaluation was accomplished by using a modified QuickDASH-9 questionnaire.
Average bone lengthening was 3.54cm, and mean lengthening index was 40.53day/cm. Eight pa-tients answered the questionnaire at a mean of 7.8yrs after the treatment. The mean questionnaire score was 9.75pts (of 36). Four patients rated the overall function of the affected limb as improved following distraction, while 3 patients were not able to see any improvement. One patient reported that the lengthening had impaired limb function. With regard to cosmetic aspects, 4 patients reported a worsening after the lengthening procedure while 3 patients reported improvement and 1 patient did not note any changes.
本研究的目的是对多年前接受前臂延长术（骨牵引）的患者进行功能（主观）和影像学评估。
共纳入 11 例各种病因导致的前臂缩短患者，共进行了 21 次延长手术。对影像学数据进行回顾性分析，并采用改良的 QuickDASH-9 问卷进行主观评估。
平均骨延长 3.54cm，平均延长指数为 40.53 天/cm。8 例患者在治疗后平均 7.8 年回答了问卷。平均问卷得分为 9.75 分（满分 36 分）。4 例患者认为牵引后患肢功能改善，3 例患者未观察到任何改善。1 例患者报告说延长术影响了肢体功能。在美容方面，4 例患者报告延长术后外观恶化，3 例患者报告改善，1 例患者未注意到任何变化。
