Disseminated tuberculosis with gradual evolution and unusual localization.

We present a case of disseminated tuberculosis (pulmonary, skeletal and lymph nodes) accompanied by subcutaneous abscesses and with unusual localization, osteolytic lesions of the skull caused by Mycobacterium tuberculosis var. hominis. Although the patient was immunocompetent, the disease had a gradual and unexpected progression.

Elastic intramedullary osteosynthesis for the treatment of metaphysodiaphyseal non-union of the femur and tibia.

Elastic osteosynthesis is capable of producing the biomechanical conditions required to reconvert mature fibro-cartilaginous tissue interposed in the non-union in bone tissue. Theory is confirmed by a retrospective study of 54 patients affected with nonunion of the femur and tibia treated with elastic osteosynthesis.

[Elastic osteosynthesis in intracapsular fracture of the femoral neck].

The authors present a method of treatment for transcervical fractures of the femoral neck using implants with mechanical characteristics--curved shape, smooth surfaces and elastic resistance to deformity--which respect the biomechanical properties of the normal bone. These implants maintain a close contact between the bony fragments during convalescence and preserve the blood supply of the bone. In this way, bone healing is encouraged and the development of ischaemic necrosis of the femoral head is prevented.

[Osteosynthesis of femoral neck fractures with 3 curved elastic nails].

The authors have treated 56 cases of fracture of the femoral neck using an original method. Three curved elastic nails were introduced into the head and neck through the greater trochanter. The results appear to be encouraging.
