[Avascular necrosis of the femoral head after transcervical fracture].
The association of transcervical fractures of the femur with avascular necrosis of the capital fragment was recognised many years ago. Nevertheless several basic questions, such as the incidence ofavascular necrosis, the extent and pattern ofbone death and revascularisation and also the role played by avascular necrosis in non-union of these fractures, remain unanswered. In the hope that a hist...
متن کاملThe histological appearances of late segmental collapse of the femoral head after transcervical fracture.
A third of severely displaced femoral neck fractures fail to unite, and of those in which sound bony union occurs, no fewer than 28 per cent later develop collapse of the upper, weight-bearing segment of the femoral head (Brown and Abrami 1964). Although the features ofthis condition have already been described by Santos (1930), Sherman and Phemister (1947), Phemister (1934, 1940, 1949), Colema...
متن کاملMRI of early osteonecrosis of the femoral head after transcervical fracture.
We have carried out a prospective study of 17 patients (14 women, 3 men) of mean age 48 years (21 to 76) with transcervical fractures of the femur using MRI to detect early evidence of avascular necrosis of the head. Two fractures were Garden stage I, 12 stage II, and three stage III. We performed internal fixation under radiological control at a mean of five days (2 to 15) after injury using a...

coronal imaging; figure 1C). She was treated with osteosynthesis (figure 1D) to stabilise the femoral neck fracture, which resulted in a good functional outcome at 6-month follow-up. Occult femoral neck fractures are frequently misdiagnosed. Once misdiagnosed, the non-displaced fracture may become displaced. When this occurs, patients may need to be treated with hip arthroplasty, which is more ...
متن کاملMechanisms of femoral fracture.
Mechanisms of femoral fracture of the condyles and shaft were experimentally investigated through controlled knee impact ofdenuded femurs in six human cadavers. High-speed movies recorded knee joint compression, femoral displacements and deformation, and fracture initiation. Fracture initiated at 10.6 + 2.7 kN knee load after 1.3 + 0.1 cm ofknec joint compression for a 10.1 kg rigid impact at 1...
