Abstract
BackgroundThis present study is aimed to retrospectively evaluate the efficacy and safety of a novel personalized navigation template in proximal femoral corrective osteotomy for the treatment of DDH.MethodsTwenty-nine consecutive patients with DDH who underwent proximal femoral corrective osteotomy were evaluated between August 2013 and June 2017. Based on the different surgical methods, they were divided into the conventional group (n = 14) and navigation template group (n = 15). The osteotomy degrees, radiation exposure, and operation time were compared between the two groups.ResultsNo major complications relating to osteotomy surgery such as redislocation or avascular necrosis occurred in the navigation template group, which had more accurate osteotomy degrees, less radiation exposure, and shorter operation time when compared with the conventional group (P < 0.05). Moreover, there was significant difference according to the McKay criteria between the two groups (P = 0.0362).ConclusionsThe novel personalized navigation template in proximal femoral corrective osteotomy is effective and safe, which could improve the femoral osteotomy accuracy, reduce radiation exposure, and shorten operation time.
Highlights
This present study is aimed to retrospectively evaluate the efficacy and safety of a novel personalized navigation template in proximal femoral corrective osteotomy for the treatment of Developmental dysplasia of the hip (DDH)
Derotational femoral shortening osteotomy as part of the surgical procedure of DDH was firstly introduced by Klisic and Jancovic as an aid to decrease the complications related with surgery such as redislocation or avascular necrosis [2]
Shi and Sun Journal of Orthopaedic Surgery and Research (2020) 15:317 on these concerns, the present study introduces a novel design and application of derotational femoral shortening osteotomy with navigation template for the treatment of DDH in children
Summary
This present study is aimed to retrospectively evaluate the efficacy and safety of a novel personalized navigation template in proximal femoral corrective osteotomy for the treatment of DDH. Other authors have regarded proximal femoral corrective osteotomy as an effective procedure for treating DDH [3,4,5]. The performance and positioning of femoral osteotomy is one of the most important surgical procedures to ensure ideal correction effects, but the conventional radiographic imaging methods, such as x-ray or CT (computed tomography), were not sufficient to provide accurate information about complex deformities [6]. Zheng et al [7] designed a 3D-printed navigation template for the proximal femoral varus rotation and shortening osteotomy.
