As part of the recovery operation on a DC9 aircraft which had crashed into the Mediterranean 7 years and 10 months before, a number of bone fragments which could be traced to a diaphysis and/or an epiphysis of long bones were recovered among the metallic parts of the aircraft at a depth of 3850 m. The bone fragments were completely free from any tissular residue, had a white-greyish color and t...

Osteoma is a benign bone-forming tumor that usually arises in the craniofacial bones and rarely in the long bones. Clavicular involvement is extremely rare. We report a 51-year-old woman with osteoma of the left clavicle. Radiograph of the left shoulder showed a well-defined lobulated blastic mass in the proximal and mid-portion of the left clavicle. Bone scintigraphy was performed 4 hours afte...

conclusions a neglected hip dislocation with acetabular fracture can be managed satisfactorily with uncemented thr. bone reconstruction using chunk grafts and use of cementless components ensures long-term survival and also preserves adequate bone stock for revision, especially in young patients. introduction posterior hip dislocation of the hip with acetabular fracture is a challenging problem...

kienbock's disease, which is an idiopathic osteonecrosis and collapse of the lunate bone, is an uncommon disease in children. this report describes a case of an 11-year-old girl, who presented with avascular necrosis of lunate bone confirmed by radiographic and magnetic resonance imaging evidence. after a short period of casting, the case was fully recovered within one year. the signal change w...

Introduction: Beta calcium sulfate hemihydrate (BCSH), which is commonly known as “Gypsum plaster” has long been used as bone graft material because of its excellent biocompatibility and the ability for bone regeneration. Several methods have been used for the preparation of BCSH, including heat treatment of calcium sulfate dihydrate with water, application of inorganic acids or condensed inorg...

Investigation of the bone and the bone marrow is critical in many research fields including basic bone biology, immunology, hematology, cancer metastasis, biomechanics, and stem cell biology. Despite the importance of the bone in healthy and pathologic states, however, it is a largely under-researched organ due to lack of specialized knowledge of bone dissection and bone marrow isolation. Mice ...

Last year’s 34th Annual Meeting of the European Paediatric Orthopaedic Society (EPOS) was held in Marseille, France, on 15–18 April. A comprehensive pre-meeting course held on 15 April was dedicated to many complex aspects of long-bone deformity correction and bonelengthening procedures. The present issue of the Journal of Children’s Orthopaedics collates manuscripts of the presentations made a...

objective: non:union: is defined as a minimum of a 9-month period of time since an injury with no visibly progressive signs of healing for 3 months. recent studies show that application of mesenchymal stromal cells (mscs) in the laboratory setting is effective for bone regeneration. animal studies have shown that mscs can be used to treat non:union:s. for the first time in an iranian population...

aneurysmal bone cyst (abc) is a benign expansile bone tumor, most commonly involving the medulla of long bones. abc rarely arises within the cortex or in the subperiosteal region, radiographically mimicking other conditions, in particular surface osteosarcomathat is low-grade in nature and may go secondary abc changes, and telangiectatic osteosarcoma. both of these are sometimes mistaken micros...

PURPOSE The present review critically evaluates existing literature on the effects of short- and long-term low energy availability (EA) on bone metabolism and health in physically active individuals. METHODS We reviewed the literature on the short-term effects of low EA on markers of bone metabolism and the long-term effects of low EA on outcomes relating to bone health (bone mass, microarchi...
