We studied the natural history of nontraumatic avascular necrosis of the femoral head (ANFH) in 115 hips in 87 patients, 69 steroid-induced, 21 related to misuse of alcohol and 25 idiopathic. The average length of follow-up was over five years. Collapse occurred most often when the focus of bone necrosis occupied the weight-bearing surface of the femoral head. Flatness of the head due to subcho...

We reviewed 11 patients (17 ankles) who had had core decompression for symptomatic avascular necrosis of the talus before collapse. The Mazur grading system was used to assess function preoperatively and at final follow-up, and radiographs were graded according to the Ficat and Arlet (1980) classification modified for the ankle. At a mean follow-up of seven years (2 to 14) 14 ankles (82%) had a...

OBJECTIVES The purpose of this study was to evaluate the effectiveness of SIGN Pediatric and Fin nails in treating pediatric diaphyseal femur fractures. DESIGN Prospective case series. SETTING Level I trauma center from 2010 to 2013. PATIENT/PARTICIPANTS Eighteen patients (13 male and 5 female) with pediatric diaphyseal femur fractures who did not achieve skeletal maturity. INTERVENTION...

The Legg-Calvé-Perthes’ disease (LCPD) is an idiopathic avascular necrosis of the femoral head, related with a disruption of the blood supply, probably initiated with a trauma. It passes through four stages: the onset of avascular necrosis; subchondral fracture; revascularization and regeneration; and healing. This condition usually appears between 5 and 9 years old and boys are more affected t...

Paediatric fractured neck of femur injuries is rare and historically has high complication rates postoperatively. We present results from the Birmingham Children's Hospital. Fifteen displaced femoral neck fractures were identified in 14 children over a 10-year period (1997-2006). Mean age at the time of injury was 10 years (range 6-14 years). Mean follow-up was 31 months (range 6-110 months). A...

Supracondylar intercondylar distal femur fractures are devastating injuries that frequently have a concurrent coronal plane fracture, which mandates dedicated operative fixation. The purpose of this study was to determine whether small-fragment cortical lag screws oriented in the sagittal plane were sufficient to stabilize coronal plane fractures associated with supracondylar intercondylar dist...

Avascular necrosis after fracture of the talus is well recognized, but is very rare in children. We report a case of avascular necrosis of the talus simulating juvenile idiopathic arthritis. The diagnosis was confirmed by open biopsy, and non-operative treatment was performed. The patient was asymptomatic with full range of motion postoperatively for two years. We hypothesize that avascular nec...

Arthroplasty is used to relieve pain associated with degenerative or inflammatory joint disease, some post-traumatic joint problems, and avascular necrosis. Avascular necrosis, inflammatory and post-traumatic problems are seen on a regular basis in areas of high HIV seroprevalence. Degenerative arthritis is rare in younger HIV patients, however. Historically the only group of HIV patients in wh...

Avascular necrosis (AVN) of the scaphoid in children is very rare and there is currently no consensus when conservative or operative treatment is indicated. A 10-year-old boy, practicing karate, presented with acute pain in his left wrist after falling on the outstretched hand. Imaging showed a scaphoid waist fracture with signs of an ongoing AVN. The diagnosis of AVN was confirmed with signal ...

BACKGROUND The purpose of this study was to compare the period of union, functional outcomes and complications of patients with femoral neck fracture treated with percutaneous cannulated screws versus dynamic hip screw (DHS). METHODS Sixty-six patients with femoral neck fracture were treated with percutaneous cannulated screws (n=33) or with DHS (n=33) between August 1999 and October 2003. Fu...
