Our purpose was to report the use of an interlocking nail-hybrid external fixator construct to correct distal femoral deformities in three dogs. Radiographs, computed tomography and a three-dimensional model were used to plan the surgical procedure. A femoral osteotomy or ostectomy was performed at the level of the centre of rotation of angulation in all three dogs. Angular and rotational deformities were corrected acutely. Distraction osteogenesis was performed to lengthen each femur postoperatively. All three dogs had additional anatomic abnormalities of the affected hindlimb complicating the correction of the distal femoral deformity. While the interlocking nail-hybrid fixator construct allowed for stable distraction of the femur, all three dogs developed complications during the postoperative convalescent period, and each had some degree of residual lameness. Lengthening the femur following acute deformity correction is problematic and additional experimental and clinical studies are warranted to decrease postoperative morbidity and improve functional results.
我们的目的是报告使用交锁髓内钉-混合外固定架结构矫正三只犬的股骨远端畸形。利用X线片、计算机断层扫描和三维模型来规划手术过程。在所有三只犬的成角旋转中心水平进行股骨截骨术或骨切除术。急性矫正角向和旋转畸形。术后进行牵张成骨以延长每只股骨。所有三只犬的患侧后肢均有其他解剖学异常，使股骨远端畸形的矫正复杂化。虽然交锁髓内钉-混合固定架结构允许对股骨进行稳定的牵张，但所有三只犬在术后恢复期均出现并发症，且每只犬都有一定程度的残余跛行。急性畸形矫正后延长股骨存在问题，需要进行更多的实验和临床研究以降低术后发病率并改善功能结果。
