Aims: The aim of this study was to analyze the effect of a lateral rim mesh on the survival of primary total hip arthroplasty (THA) in young patients, aged 50 years or younger.

Patients And Methods: We compared a study group of 235 patients (257 hips) who received a primary THA with the use of impaction bone grafting (IBG) with an additional lateral rim mesh with a group of 306 patients (343 hips) who received IBG in the absence of a lateral rim mesh during the same period from 1988 to 2015. In the mesh group, there were 74 male and 183 female patients, with a mean age of 35 years (13 to 50). Read More

Introduction: The pathophysiology of rapidly progressive hip disease is still unclear. It is a rare subset of osteoarthritis that mainly affects elderly women and presents with new- onset severe hip pain and dysfunction. It is assumed to be triggered by extremely rapid osteoarthritic changes resulting in impaction of the femoral head into the acetabulum, with successive osteonecrosis and insufficiency of the femoral head.

Avascular necrosis (AVN), also known as osteonecrosis, is characterized by death of the osteocytes due to inadequate blood supply caused by various mechanisms. The hip is the most common affected joint followed by knee. Incidence of AVN in rheumatic diseases is variable and high corticosteroid (CS) therapy is a known major risk factor for development of AVN. Read More

Introduction:: The purpose of this study was to investigate the incidence of necrosis and insufficiency fracture of the hip and knee using magnetic resonance imaging (MRI) in renal transplant patients.

Methods:: We examined 300 consecutive renal transplant patients using MRI of the hips and knees (T1-weighted coronal MRI) preoperatively and at 3 and 6 months postoperatively. Oblique axial-plane T1-weighted MRI and short-tau inversion-recovery T2-weighted MRI were performed parallel to the femoral neck when distinguishing the osteonecrosis of the femoral head (ONFH) from subchondral insufficiency fracture (SIF) of the femoral head was difficult.

Osteonecrosis of the femoral head occurs because of the suppression of blood circulation. At the level of the area affected by the ischemic phenomenon, there are two types of events, in the first stage there is necrosis of the cellular elements, followed by a reparatory phase of the spongy bone tissue. The objective of the study was the histological and immunohistochemical (IHC) analysis of bone metabolism in the repair phase. Read More

Due to the inherent stability of the hip joint, hip dislocations constitute a relatively small proportion of all the traumatic dislocations encountered in the emergency department. Among them, the anterior type of hip dislocation is less common than the posterior type of dislocation. Anterior dislocations are usually associated with an injury to other, nearby structures like the acetabulum and femoral head. Read More

Multifocal avascular osteonecrosis (AON) is a serious manifestation of systemic lupus erythematosus (SLE). Prothrombotic factors, especially antiphospholipid antibodies (aPL), have been associated with the development of AON; therefore, attenuating the procoagulant state while balancing the haemorrhagic risks might have a rationale when managing this condition. We report a case of a 37-year-old patient with SLE, treated with low doses of corticosteroids and immunosuppressive therapy, who was started on vitamin K antagonist following an episode of deep vein thrombosis while having persistent positivity for aPL.

Denosumab is a fully human monoclonal antibody to receptor activator of nuclear factor kappa-B ligand (RANKL), a cytokine expressed by cells of the osteoblast lineage that is a key regulator of osteoclastic bone resorption. By binding and neutralizing RANKL, denosumab inhibits osteoclast differentiation, activity, and survival. Clinical trials in postmenopausal women with osteoporosis have shown that it reduces the risk of vertebral fractures, nonvertebral fractures, and hip fractures, with a generally favorable safety profile.
