Dysplastic nevus is an acquired or hereditary nevus that clinically seems atypical and pathohistologically dysplastic. The term of dysplastic nevus has changed through history and even until now the dermatologists and pathologists have not found the same conclusion for name and definition of dysplastic nevus. Epidemiology of dysplastic nevus is different depending on geographic lattitude, being...

hip dislocation occurs when the femur does not break and the force is transmitted towards the hip joint leading to a posterior dislocation of the femoral head with or without posterior acetabular fracture. we present the case of a 26 year old patient involved in motor vehicle accident. clinical and imaging (radiography, ct) examination revealed an intertrochanteric fracture associated with ipsi...

The hip joint is one of the largest weight bearing structures in the human body. While its efficient structure may lend to a lifetime of mobility, abnormal, repetitive loading of the hip is thought to result in osteoarthritis (OA). The etiology of hip OA is unknown however, due to the high loads this joint supports, mechanics have been implicated as the primary factor. Quantifying the relevant ...

BACKGROUND The aim of the study was to analyse the outcomes of hip replacement complicated by intraoperative femoral fractures and to analyse their effective management. MATERIALS AND METHODS The medical records of 43 cases of intraoperative femoral fractures (1.4% of all hip replacements) were retrospectively reviewed. The patient group included 29 females. Patients' age ranged from 20 to 66...

BACKGROUND Different extents and locations of acetabular cartilage defect have been supposed to be a major cause of undesirable outcomes of periacetabular osteotomy (PAO) in patients with developmental dysplasia of the hip (DDH). This study aimed to verify whether different locations of cartilage deficiency affect the biomechanical environment in a three-dimensional model utilizing finite eleme...

We have reviewed 54 patients who had undergone 61 total hip replacements using bulk femoral autografts to augment a congenitally dysplastic acetabulum. There were 52 women and two men with a mean age of 42.4 years (29 to 76) at the time of the index operation. A variety of different prostheses was used: 28 (45.9%) were cemented and 33 (54.1%) uncemented. The graft technique remained unchanged t...

BACKGROUND Severe acetabular deficiencies in cases of developmental dysplasia of the hip (DDH) often require complex reconstructive procedures in total hip arthroplasty (THA). The use of autologous femoral head grafts for acetabular reconstruction has been described, but few data is available about clinical results, the rates of non-union or aseptic loosening of acetabular components. METHODS...

Triple pelvic osteotomy (TPO) is one of the main surgical procedures to prevent or modify the progress of degenerative joint disease (DJD) related with hip dysplasia in young dogs. The aim of this study was to evaluate the effects of TPO in dogs. In this study, TPO were performed in 7 dysplastic cross-breed dogs in different gender (6 female and 1 male) and body weight (13.42±2.29 kg). In all c...

BACKGROUND We evaluated the clinical and radiological results of one-stage correction for cerebral palsy patients. METHODS We reviewed clinical outcomes and radiologic indices of 32 dysplastic hips in 23 children with cerebral palsy (13 males, 10 females; mean age, 8.6 years). Ten hips had dislocation, while 22 had subluxation. Preoperative Gross Motor Function Classification System (GMFCS) s...
