The type of bearing material that should be used in revision surgery after the failure of ceramic-on-ceramic total hip arthroplasty (THA) remains controversial. In the case of ceramic fracture, the residual ceramic particles can cause consequent metallosis when metal implants are used for revision THA. On the other hand, in the case of THA failure without ceramic fracture, revision THA with a metal femoral head provides satisfactory results. We report an unusual case of progressive osteolysis due to metallosis that developed after revision THA for ceramic liner dissociation without a liner fracture performed using a metal femoral head and polyethylene liner. The residual metal debris and abnormal pumping motion of the polyethylene liner due to the breakage of the locking system or the aspherical metal shell being abraded by the ceramic head seemed to be the cause of the progressive osteolysis.

Background: Heterozygous TRPV4 mutations cause a group of skeletal dysplasias characterized by short stature, short trunk, and skeletal deformities.
Objective: The aim of this study is to compare the natural history of clinical and radiologic features of patients with different TRPV4-related skeletal dysplasias.
Materials And Methods: Thirteen patients with a mutation in TRPV4 were included in the study, and 11 were followed for a median of 6.

Background: Length unstable femoral shaft fractures in school-aged children usually demand surgical treatment, but the optimal choice remains controversial, especially in overweight adolescents. This study aimed to compare the clinical results of locking compression plates (LCP) and elastic stable intramedullary nails (ESIN) combined with temporary external fixator (TEF) in school-aged children weighing over 50 kg.
Methods: Between January 2010 and January 2018, children over 50 kg with length unstable femoral shaft fracture treated with ESIN & EF in the authors' institute were included in this study.

Background: The effects of surgical treatment on the quality of life (QOL) of patients who have osteonecrosis of the femoral head (ONFH) have been rarely reported. This multicenter study aimed to elucidate the longitudinal QOL in patients who have ONFH undergoing total hip arthroplasty (THA).
Methods: Self-assessment QOL questionnaires, including the Japanese Orthopaedic Association Hip Disease Evaluation Questionnaire (JHEQ), Oxford Hip Score (OHS), and 12-Item Short-Form Health Survey Version 2 (SF-12v2), were administered to 124 patients at six months, one year, two and five years postoperatively.

Introduction: Global coronal alignment is mainly assessed by C7 plumbline and central sacral vertical line (CSVL), pelvic obliquity and shoulder alignment. A detailed analysis is mandatory when treating spinal deformity. It remains unclear to what extent mild scoliosis influences global coronal alignment.
