Article Synopsis
- This study investigates the time from diagnosis to surgery for osteonecrosis of the femoral head (ONFH) and factors affecting its severity among 2074 cases in Japan from 1997 to 2018.
- The median time to surgery was found to be 9 months, influenced by whether the patient used alcohol or corticosteroids, and the stage of joint destruction at diagnosis.
- The study highlights that a large proportion of patients remain untreated for extended periods, but surgery was performed within 9 months for more than half of the patients, indicating the disease's serious impact.
Article Synopsis
- * A genome-wide association study (GWAS) was conducted to uncover genetic risk factors for steroid-associated ONFH (S-ONFH) in SLE patients, involving data from 636 SLE patients with S-ONFH and nearly 96,000 controls.
- * Four significant genetic loci were identified, with three showing strong associations with S-ONFH, suggesting potential common genetic factors between S-ONFH and SLE, particularly implicating genes involved
Objective: Rapidly destructive coxopathy (RDC) is a rare condition characterized by rapid joint space narrowing; however, its pathology remains unclear. This study aimed to clarify the association of laboratory biomarkers with the radiological progression of RDC.
Methods: We examined 34 female and 4 male patients with RDC between October 2010 and April 2018.
The authors report a case of immunoglobulin G4-related disease (IgG4-RD) of the hip. A 60-year-old man diagnosed with osteoarthritis of the right hip was referred to the authors' outpatient clinic for surgical intervention. Laboratory test results revealed elevated C-reactive protein and serum IgG levels.

We compared clinical outcome, blood metal ion levels, and the incidence of pseudotumour in the two groups.
Patients And Methods: Between December 2009 and December 2011, 62 patients underwent MoM THA with a large femoral head (Magnum group) and 57 patients an MoM THA with a conventional femoral head (conventional group).
