BUILDING OF EXTENSIVE DIAPHYSIS DEFECTS IN LONG BONES

The problem of extensive diaphysis bone defect replacement in long bones has been investigated. Treatment results of three patients (one with neoplastic process, two with supparative bone damage) are given. The sizes of defects were from 16 to 20 cm. Su pervision terms consisted 1-3 years. There were two defect replacement variants: cellular titanium nickelide alongside with interlocking internal fixation - in 2 patients, and metallic prosthesis of ProSpon company (Czech Republic) - in 4 patients. Two patients after segmental resection of limb bone tumours and diaphysis endoprosthesis show positive treatment results. Long-term treatment by different methods in 4 patients with chronic fistulous form of post-traumatic osteomyelitis were unsuccessful

SOME ASPECTS OF DIFFERENTIAL DIAGNOSTICS OF GIANT-CELL TUMOUR, OSTEOCYSTOMA AND OSTEOSARCOMA

The problems of timeliness and correctness of diagnostics of bone tumours, as well as therapeutic decision deserve the most careful consideration. The present research concerns the detection of criteria of differential diagnostics of giant-cell tumours, osteocystoma and osteosarcoma (according to the literary data). According to the literature the study of clinical and radiologic diagnostics, allowed to work out differential and diagnostic tables of signs and algorithms of diagnostics of giant-cell tumours, osteocystoma and osteosarcoma. It enabled to detect a therapeutic and diagnostic approach to patients with bone tumours
