Diagnosis of bone and joint infection by leucocyte scintigraphy. A comparative study with 99mTc-HMPAO-labelled leucocytes, 99mTc-labelled antigranulocyte antibodies and 99mTc-labelled nanocolloid.
Fifty-five patients with 60 suspected infections of bones or joints were studied with 99mTc-hexamethylpropyleneaminooxine- (HMPAO-) labelled leucocytes and 99mTc-labelled antigranulocyte antibodies, in part supplemented with 99mTc-labelled nanocolloid. The findings using the different procedures were in good agreement. ⋯ Spondylitis usually shows as non-specific cold lesions. A subtraction technique with computer assisted analysis of HMPAO and nanocolloid scans provides a more precise diagnosis of this condition.

Vascularized pedicled bone graft into the femoral head--treatment of aseptic necrosis of the femoral head.
Revitalization of the femoral head in cases of aseptic necrosis was attempted in 13 hips of 11 patients 15-33 years of age. The necrotic bone was replaced by a vascularized pedicular iliac bone graft and free cancellous transplants. The results after an average follow-up of 53 months are satisfying in some cases. The surgical technique used is simple and applicable when a vascularized bone graft is needed in the hip region.

Case ReportsBizarre parosteal osteochondromatous proliferation of a phalanx.
A rare proliferative osteochondromatous malformation of a proximal phalanx is described. This malformation may mimic the appearance of a sessile osteochondroma or parosteal osteosarcoma on X-rays and may be mistaken for a low-grade osteosarcoma on histology, with disastrous therapeutic consequences. We found that cryotherapy followed by local excision was adequate to remove the tumour.

Comparative StudyThe APS knee joint prosthesis. A review of 32 patients.
First clinical and radiographic results with a new knee joint prosthesis, implanted without cement, are reported and the characteristics of the implant (dowel fixation and special instrumentation) presented. The first series of 35 joints with a follow-up period of 1-3 years shows excellent results. ⋯ If these two conditions are met, there is every probability of successful implantation. No problems specific to the implant have been encountered.

Trauma centers treat more and more patients who have sustained multiple injuries during high energy accidents. The techniques of internal fixation of such fractures may be dictated by the concomitant soft tissue trauma, rather than by the bony injury. ⋯ In stage III, the soft tissues about the fracture site are destroyed and need early, specific soft tissue reconstruction. Indirect reduction without further devascularization of bone, aiming at perfect alignment rather than anatomical reduction of extraarticular fractures, optimal rather than maximal internal fixation as well as the inclusion of soft tissue reconstructive procedures into the armamentarium of the orthopaedic surgeon, require an intellectual and technical reorientation but can be shown to improve the results of the treatment of fractures with concomitant soft tissue injury.
