The purpose of this study was to elaborate “sparing” surgical treatment of benign tumors and tumorlike lesions of bones in children

Ninety-six experiments on human defrosted tibias and twenty-four operations on chinchilla rabbits showed the effect of co2-laser radiation on osteal structures.the clonation of human bone marrow (one hundred ad nineteen cultures) and seventy-two experiments on chinchilla rabbits revealed the effect of uv-radiation on osteogenesis. The clinical study included five hundred and fifty-seven children with benign tumors and tumorlike lesions of bones.

Experimental and clinical investigation showed that co2-laser scanning of residual bone cavity after economic resections prevented relapses of pathological process in 98% cases.osteoplasty with uv-radiated autologus bone marrow in combination with allo-bone material stimulated osteogenesis and provided restoration of bone structure in nine to twelve months.

c02-laser operations with simultaneous osteoplasty by uv-radiated autogenous bone-marrow is an effective “sparing” method of surgical treatment of benign tumors and tumorlike lesions of bones in children.
