BACKGROUND Ochronosis is connective tissue manifestation of Alkaptonuria. Joint involvement specially hip and knee destruction is seen. The cartilage is pigmented and destroyed. It is interested for both pathologists and orthopedic surgeons. CASE PRESENTATION A 54 years old woman with hip fracture after simple falling is candidate for surgery, but, after skin and subcutaneous incision over de...

A unicameral bone cyst (UBC) may require surgery if its location increases the risk for pathologic fracture, or if it is painful or increasing in size. This case series demonstrates that curettage and grafting with a bone graft substitute alone can result in healing of the UBC. Three children with UBC and pathological fractures were treated with curettage and grafting using bone graft substitut...

Introduction: The blood supply as well as mechanical factors are known to guide the fracture healing process [1-4]. Revascularization, tissue differentiation and local mechanical conditions depend on each other in a very complex manner. Mathematical models have been developed to describe the time dependent callus formation during fracture healing. [5-8]. However, previous models did not take in...

The purpose was to detect the effects of ovariectomy (OVX) on femoral fracture healing through different angiogenesis and HIF-1α expression in mice. Thirty-six young female C57 mice were randomized into two groups: OVX and age-matched intact control (CON). The femoral fracture was generated at 3 weeks after OVX or CON. At 2 or 4 weeks after fracture, the femoral fracture area was evaluated heal...

A pathologic fracture is every fracture caused by minimal trauma of the bone weakened by some process (osteoporosis, tumor, etc.). Most common pathological spine fractures are compressive fractures of thoracolumbal vertebras in geriatric patients. Considering the fact that geriatric population often have numerous comorbidities, weakened bone quality, and that instrumented spondylodeses have inc...

Angular deformities of the distal femur occur in congenital diseases or due to acquired causes, such as malunion after a fracture of the distal femur. Angular deformities of the lower extremities affect the mechanical axis, causing changes in the weight pressure on the articular surface. As a result, angular deformities quicken the progression of osteoarthritis. Therefore, correction of deformi...

Extramammary Paget disease (EMPD) is an uncommon malignancy. It manifests either in the primary form in the skin as an intraepithelial neoplasm, or in secondary form as pagetoid (intraepithelial) spread of an underlying internal carcinoma to the skin. Although local invasion and recurrence of primary extramammary Paget disease are relatively frequent, widespread metastases are rare. As such, th...

OBJECTIVES The aim of this study was to evaluate the implication of third molars in postoperative complications of mandibular angle fracture with open reduction and internal fixation (ORIF). MATERIALS AND METHODS Data were collected on patients who presented with mandibular angle fracture at our Department of Oral and Maxillofacial Surgery between January 2011 and December 2015. Of the 63 tot...
