PURPOSE The recovery of a bone fracture is a process that is not yet fully understood. The literature conflicts on the results obtained by the interposition of foreign tissue inside a damaged bone. The objective of the present study was to ascertain the effect of placing muscle tissue between the stumps of a fractured bone. METHOD The study was carried out on 10 rabbits divided into 2 groups ...

Osteochondral lesions most commonly occur about the knee but may affect any articular surface of the pediatric appendicular skeleton. Osteochondral lesions include osteochondritis dissecans, osteochondral fractures, and osteochondral abnormalities associated with secondary processes such as Legg-Calvé-Perthes disease. These abnormalities should not be confused with normal subchondral irregulari...

INTRODUCTION Acute posterolateral rotator elbow dislocation in a child is rare and can be easily misdiagnosed due to immaturity of the epiphysis. This is the first case of occult posterolateral rotator elbow dislocation in combination with an olecranon fracture. We report our experience with this case, which was not diagnosed correctly by plain radiographs. CASE PRESENTATION An 11-year-old As...

INTRODUCTION Lunate fracture is a rare injury. Most reports are associated with other wrist injuries such as perilunate dislocation and distal radius fracture. Isolated lunate fracture has been reported even more rarely. The choice of treatment and outcomes are consequently undetermined. CASE PRESENTATION In this case report we will describe a lunate avulsion fracture as an isolated injury af...

PURPOSE To assess the outcome of open reduction and internal fixation combined with surgical dislocation of the hip for displaced acetabular fractures. METHODS 20 men and 2 women aged 20 to 55 (mean, 28) years underwent open reduction and internal fixation combined with surgical dislocation of the hip for displaced acetabular fracture. The most common fracture pattern was bicolumnar (n=12), f...

Loss-of-function mutations in the Notch ligand, Jagged1 (Jag1), result in multi-system developmental pathologies associated with Alagille syndrome (ALGS). ALGS patients present with skeletal manifestations including hemi-vertebrae, reduced bone mass, increased fracture incidence and poor bone healing. However, it is not known whether the increased fracture risk is due to altered bone homeostasi...
