    摘要:

    [目的] 介绍斜形单平面旋转截骨术矫正股骨多平面畸形的术前设计,手术技术和临床应用效果。[方法] 对1例股骨骨折畸形愈合患者进行术前设计,确定截骨角度和旋转角度,在Mimics软件上模拟手术,3D打印制作截骨导板,对该病例行斜形单平面旋转截骨手术治疗。取股骨外侧纵行切口,显露畸形部位,安放截骨导板,按术前设计完成截骨、旋转,截骨断端用髓内钉固定,断端取髂骨植骨。[结果] 手术过程顺利,术后无不良并发症,术后6个月复查,患者不再跛行,膝关节无疼痛,CT证实骨断端完全愈合。[结论] 斜形单平面旋转截骨术切实可行,一次截骨同时矫正股骨在冠状面、矢状面和旋转畸形,短期可取得满意的临床疗效。

    Abstract:

    [Objective] To introduce the preoperative design, surgical technique and clinical application effect of oblique single-cut rotation osteotomy corrects polyplanar deformity of femur. [Methods] One patient with malunion of femoral fracture was preoperatively designed, the osteotomy angle and rotation angle were determined, the operation was simulated on Mimics software, and the osteotomy guide plate was made by 3D printing. The case was treated with oblique single-cut rotation osteotomy. A longitudinal incision was made on the laterlal side of the femur to expose the malunion, an osteotomy guide was placed, and the osteotomy and rotation were completed according to the preoperative design. The fractured end of the osteotomy was fixed with intramedullary nails, and taken from the iliac bone for bone grafting. [Results] The operation was safe and there were no adverse complications after operation. After 6 months of follow-up, the patient was no longer limping, and no pain in the knee joint. CT confirmed that the fractured bone was completely healed. [Conclusion] The oblique single-cut rotation osteotomy is feasible, that can osteotomy, correct the coronal, sagittal and rotational deformities of the femur at the same time. A satisfactory clinical effect can be achieved in the short term.
