Bypass of Epiphyseal Fragmentation Following Early Salter Innominate Osteotomy and Its Clinical Relevance in Legg-Calvé-Perthes Disease.

J Pediatr Orthop 2022 May-Jun 01;42(5):239-245

Department of Orthopaedic Surgery, Aichi Children's Health and Medical Center, Obu, Aichi, Japan.

Background: It has been demonstrated that early femoral varus osteotomy (FVO) produces a greater probability of skipping or interruption of epiphyseal fragmentation, thereby shortening the length of fragmentation stage for hips in the active stage of Legg-Calvé-Perthes disease. This "bypassing phenomenon" is thought to effect less disease severity or outcome, whereas it remains to be elucidated whether this phenomenon is specific to early FVO. We sought to investigate the presence and characteristics of the "bypassing phenomenon" following pelvic osteotomy performed in the avascular necrosis or early fragmentation stage as well as its correlation with disease severity and radiographic outcomes.

Increased psoas tendon running angle in patients with Legg-Calvé-Perthes disease: a new theory for the aetiology of children with avascular femoral head necrosis.

J Pediatr Orthop B 2022 Mar;31(2):e160-e166

Department of Pediatric Orthopaedic Surgery, Osaka City General Hospital, Osaka, Japan.

The cause of Legg-Calvé-Perthes disease (LCPD) remains unknown. We propose a new hypothesis that the iliopsoas muscle and/or tendon affects the progression of ischemic necrosis of the femoral head as an anatomical factor. The purpose of this study was to test this hypothesis by measuring the psoas major tendon angle (PMTA) and cross-sectional area (CSA) of the iliopsoas muscle on MRI. Read More
