“…Hip preservation surgery is a growing field, with broad recognition that certain surgically approachable deformities are associated with abnormal mechanics that predispose patients to hip OA [8,9,10,29,30,35,36,42,49,69,73]. However, there are many mechanical and nonmechanical factors [11,67] that can affect clinical function in the at-risk hip and thus influence patient-perceived outcomes of surgical treatment [25,51].…”

“…He posited that the usual acetabular deformity and much of the instability in developmental dysplasia could be treated effectively by a novel iliac osteotomy [64]. By the 1970s, developmental deformity was recognized as the most common cause of hip OA in much of the world [1,69,71]. Innovative acetabular re-directional osteotomies were developed by Nishio [53] and Tagawa [60] in Japan.…”

“…The following parameters were measured: MP, center-edge angle (CEA), NSA, teardrop distance (TDD), [7] a break in Shenton's line (SL), sharp's angle (SA), acetabular ridge angle (ARA), [8] and the change in the MP ratio (Change MP). SL is an imaginary curved line drawn along the inferior border of the superior pubic ramus (superior border of the obturator foramen) along the inferomedial border of the neck of the femur (Fig.…”

Femoral varus derotational osteotomy without pelvic osteotomy in nonambulatory children with cerebral palsy

Whether femoral varus derotational osteotomy (VDRO) alone or a combination of femoral and pelvic osteotomies should be performed for hip dislocation in nonambulatory children with cerebral palsy (CP) remains controversial. Few studies have reported radiographical results after the surgical treatment in nonambulatory children with CP. This study aimed to assess the results and determine predictors indicating progressive hip subluxation and redislocation after VDRO without pelvic osteotomy. We retrospectively analyzed 22 hips in 15 nonambulatory children with CP. All patients underwent VDRO without pelvic osteotomy and were followed up for at least 5 years. The mean follow-up period was 7.3 ± 1.9 years. In radiological assessments, we investigated migration percentage (MP), center-edge angle, neck-shaft angle, teardrop distance, break in Shenton's line (SL), sharp's angle, acetabular ridge angle (ARA), and the change ratio of MP (Change MP). We classified patients with an MP of <40% at final follow-up in the Good group and those with an MP of ≥40% in the Poor group. The Good group included 10 children (14 hips), and the Poor group included 8 children (8 hips). No preoperative differences were found in the means of all the radiographical parameters. However, MP was significantly different between the groups from 1 year postoperatively. ARA showed improvement 5 years after surgery in the Good group. Change MP in the Good group was maintained from immediately after surgery to the final follow-up. Multivariate logistic regression analyses revealed that preoperative break in SL and Change MP immediately after surgery were parameters to predict MP at the final follow-up. In the receiver operating characteristic analysis, the cut-off values were estimated to be 19.2 mm for preoperative SL and 79.0% for Change MP immediately after surgery. Within 7.3 years of follow-up, 63.6% of the patients who underwent VDRO without pelvic osteotomy had good results. Preoperative SL and postoperative Change MP can be considered as predictors of postoperative subluxation and/or dislocation.

“…It has been shown to become negative in cases of slipped capital femoral epiphysis [ 25 ]. On the AP pelvic radiograph, the asphericity of the femoral head-neck junction can appear as a pistol grip deformity [ 64 ]. Severe asphericities such as sequelae of LCPD appear with a sagging rope sign on the AP radiograph [ 65 ].…”

Following the recognition of femoroacetabular impingement (FAI) as a clinical entity, diagnostic tools have continuously evolved. While the diagnosis of FAI is primarily made based on the patients’ history and clinical examination, imaging of FAI is indispensable. Routine diagnostic work-up consists of a set of plain radiographs, magnetic resonance imaging (MRI) and MR-arthrography. Recent advances in MRI technology include biochemically sensitive sequences bearing the potential to detect degenerative changes of the hip joint at an early stage prior to their appearance on conventional imaging modalities. Computed tomography may serve as an adjunct. Advantages of CT include superior bone to soft tissue contrast, making CT applicable for image-guiding software tools that allow evaluation of the underlying dynamic mechanisms causing FAI. This article provides a summary of current concepts of imaging in FAI and a review of the literature on recent advances, and their application to clinical practice.
