[Early diagnosis and management of femur head necrosis in young adult age].

There are a lot factors in the genesis of the ischemic femoral head necrosis. In the early stage the intraosseous pressure increases without any clinical or radiological sign. The disease is often bilateral.

[Is remodeling still possible after collapse in femur head necrosis?].

A case of a femoral head necrosis, with collapsed joint surface after fracture of the femoral neck will be presented. Following varisation osteotomy, the necrotic parts of the bone was removed and filled with cancellous bone. A standardized bone block of the iliac crest was implanted into the hole.

[Talus substitution using a vascular pedicled bone flap].

Authors report on the substitution of in consequence of complete talus luxation, missing talus. It succeeded with the transplantation of a free vascular pedicled bone block, gained from the crista ilei to retain the length of the extremity and to secure the gait of the patient without aid, finally to make the return to the former active life possible. The use of the method in similar cases was found to be unknown after a review of the literature.

[Aseptic femur head necrosis and therapeutic possibilities by using a bone graft with a vascular pedicle].

The review of the occurrence, etiopathology, classification and diagnosis of the aseptic necrosis of the femoral head is followed by the description of the method of transplantation of the vascular pedicled bone graft. During 5 years implantation of 12 vascular pedicled bone grafts in 10 young patients with severe and of major extension necrosis of the femoral head was carried out. The early result was in every case the quick and significant decrease of pains and that the necrosis did not progress.

[Osteosynthesis of femoral neck fractures by double-cannulated screws (preliminary report)].

Authors report on a new osteosynthesis based on the double nailing of femoral neck fracture and screwing, and developed from the "Uppsala" double screwing. The preliminaries of the double cannulated screwing method, its advantages, the experiences gained in 30 cases operated in one year and the early results are described.
