BackgroundContemporary total hip arthroplasty (THA) employs larger femoral heads to optimize stability. However, the combination of large and comparatively small acetabular components poses a potential risk for implant failure secondary polyethylene (PE) liner fracture or dissociation. The purpose this study was evaluate incidence dissociation, survivorship, PE wear rates in primary THAs using ...

We present a case of paediatric Stage IV sporadic Burkitt's leukaemia presenting as cheek enlargement with osteolysis of the maxilla. An 8-year-old boy was referred to our department with diffuse swelling of both cheeks. Head and neck examination revealed bilateral diffuse nontender swelling, non-fluctuant but slightly compressible. Computed tomography imaging showed enhancing bilateral bulky l...

In order to test the effect of diphosphonates in inhibiting bone lysis induced by human tumors, neonatal mouse calvaria are cultured in sterile conditions in different media. Osteolysis is estimated by the amount of 45Ca released from bone to medium, the mice being given injections of 45Ca on their day of birth. An increased bone lysis is observed when calvaria are incubated in the same medium ...

Abstract Aim We report a rare case of juvenile hyaline fibromatosis (JHF) leading to acro-osteolysis bilateral hands in 54-year-old male patient. Method JHF is an autosomal recessive condition resulting from mutation the ANTXR2/ CMG2 gene. It results accumulation amorphous deposits skin and other organs. Other cardinal manifestations include gingival hyperplasia, flexion contracture large joint...

Idiopathic osteolysis is characterised by a spontaneous onset without previous causative factors, followed by rapid destruction and resorption of the involved bones. This process can result in severe deformities with joint subluxation and instability. In certain forms an associated malignant nephropathy may develop. A case report is presented which illustrates the destructive nature of the proc...

background: modern knee designs have popularized its use in younger patients due to its better performance. there remains uncertainty whether higher demands of these patients can affect implant survivorship.    purpose: to assess whether modern knee designs have provided similar results in patients younger than 70 years versus older patients. methods: we included 203 consecutive patients (236 k...
