The treatment of femoral nonunion is challenging for both the surgeon and the patient. Strut allografts increase the bone stock, enhance fracture healing and increase stability by acting as a biological plate. In this study, we aimed to report the results of the sandwich technique with two-strut allograft in the treatment of oligotrophic or atrophic femoral nonunions.
Medical records of the patients who were treated due to femoral nonunion in a single center were retrospectively reviewed. Twenty-one patients (10 males, 11 females) with a mean age of 49 (range: 21 to 79) years were included in the study. The left side was affected in 11 patients, whereas the right side was affected in ten. The patients had 11 femoral shaft fractures, seven proximal femoral fractures and three distal femoral fractures. The mean time from the previous operation to the nonunion surgery was 9.6 (range: 6 to 22) months.
Union was achieved in all patients after a mean period of 6.2 (range: 4 to 10) months. The mean follow-up time was 46.8 (range: 12 to 86) months. One patient had superficial surgical site infection in the autologous graft donor site.
The sandwich technique with two-strut allograft provides good results in the treatment of femoral nonunion. The technique can be used on any type of nonunion, at any segment of the femur and can be combined with different fixation techniques.
股骨骨不连的治疗对医生和患者都是一个挑战。支撑同种异体移植物通过充当生物板增加了骨量，增强了骨折愈合并增加了稳定性。在这项研究中，我们旨在报告使用两支柱同种异体移植物治疗少或萎缩性股骨骨不连的夹心技术的结果。
回顾性分析单中心因股骨骨不连而接受治疗的患者的病历。研究纳入 21 名患者（10 名男性，11 名女性），平均年龄为 49 岁（范围：21 岁至 79 岁）。11 名患者的左侧受累，10 名患者的右侧受累。患者中有 11 例股骨干骨折、7 例股骨近端骨折和 3 例股骨远端骨折。从上次手术到骨不连手术的平均时间为 9.6 个月（范围：6 至 22 个月）。
所有患者在平均 6.2 个月（范围：4 至 10 个月）后均实现了愈合。平均随访时间为 46.8 个月（范围：12 至 86 个月）。1 名患者在自体移植物供体部位出现浅表手术部位感染。
使用两支柱同种异体移植物的夹心技术在治疗股骨骨不连方面取得了良好的效果。该技术可用于任何类型的骨不连，在股骨的任何部位，并可与不同的固定技术结合使用。
