Noting that Perthes' disease is relatively common in Caucasian British children compared with black African children, this study was carried out to compare the range of hip movements in a series of 100 normal Ghanaian children and 182 normal British children, between 5 and 6 years of age. A significantly increased range of movement was found in the African group in all parameters, (P<0.001). The changes were even more marked when sex was taken into consideration, female children having a much bigger range of movement than the males in both racial groups. The unaffected hips in a series of 51 Caucasian children presenting with unilateral Perthes' disease were then analysed and were found to have a reduced range of movement compared with normal, in flexion, abduction, internal rotation in flexion and external rotation in extension (P<0.001). It is suggested that one of the reasons why some hips are vulnerable to Perthes' disease could be a preexisting restricted range of movement, which renders them more susceptible to strain injuries.

Background: Proximal femoral varus osteotomy (PFVO) is commonly performed to improve femoral head containment and decrease deformity in Legg-Calve-Perthes disease (LCPD). Little is known about how PFVO impacts the quality of life after surgery. The purpose of this study was to determine the longitudinal changes to patient-reported physical, mental, and social health measures after PFVO.

: Legg-Calvé-Perthes disease (LCPD) is characterized by idiopathic avascular necrosis of the femoral head in children. There are several hypotheses regarding the cause of LCPD; however, the exact cause remains unclear. Studies on comorbidities can provide better insight into the disease.

Legg-Calvé-Perthes Disease (LCPD) is a condition marked by temporary blood flow disruption to the proximal femur, commonly afflicting children aged 15 and younger. The etiology of the disease is often idiopathic and involves the development of avascular necrosis of the femoral head, subsequently leading to bone weakening and deformity. Obesity exacerbates LCPD, correlating with delayed diagnosis, increased disease severity, and bilateral involvement.

Aims: We evaluated the national and regional trends from 2013 to 2022, in the prevalence of Perthes' disease among adolescent males in South Korea.
Methods: This retrospective, nationwide, population-based study included a total of 3,166,669 Korean adolescent males examined at regional Military Manpower Administration (MMA) offices over ten years. Data from the MMA were retrospectively collected to measure the national and regional prevalence per 100,000 and 95% CI of Perthes' disease according to the year (1 January 2013 to 31 December 2022) and history of pelvic and/or femoral osteotomy in South Korea.

Background: The purpose of the study was to analyze the appearance of pelvic obliquity before total hip arthroplasty (THA) in adults who have Legg-Calvé-Perthes disease (LCPD) sequelae and its evolution in the first two postoperative years, identifying which factors influence its development.
Methods: The THAs performed between 2012 and 2021 at a single institution in adults who had LCPD during childhood were retrospectively identified. Each case was matched 1:1, based on age at surgery, sex, and body mass index, with a primary THA performed for hip osteoarthritis (primary OA).
