Osteosarcoma is the most common primary malignant neoplasm of bones in children; this tumor accounts for 50 to 80% of all skeletal sarcomas. Less often, osteosarcoma affects flat bones (scapula, ribs, bones of the skull and pelvis), bones of the foot, hand and spine. Description of the observation. A 13-year-old girl, 8 months before admission to the clinic, began to complain of pain in her right hand, six months later, a swelling appeared in this area. After radiography, which revealed a bone tumor of the III metacarpal bone, a trepanobiopsy with histological examination was performed. Conclusion: subperiosteal telangiectatic osteosarcoma G II. The child was admitted to the oncology department in November 2018. Before the operation, the girl underwent 4 courses of chemotherapy, as a result of which the tumor reduced in size, which made it possible to perform organ-preserving surgical treatment extirpation of the third metacarpal bone affected by the tumor, followed by autoplasty from the wing of the right iliac bone with fixation of the graft Kirschner needles. The postoperative period passed without complications. As a result of the operation, it was not only possible to radically remove the tumor, but also to preserve 3 fingers of the right (working) hand with good functionality. After surgery, the child received 5 courses of polychemotherapy and is currently in remission. Conclusion. The above observation demonstrates the possibility of performing organ-preserving surgeries using bone autoplasty for rare tumor lesions of the metacarpal bones. This method is more physiological in comparison with the use of allo- or artificial grafts.

Ninety five patients (mean age 13.72±4.2) with complaints on loco-motor system disorders after special treatment for malignant tumors were under observation of orthopaedic surgeon. The most common sequelae of treatment were muscular hypotrophy (66 children), I-III degree scoliosis (75), rigidity (61), bone metabolism disorder and osteopenia (47), one limb shortening even in presence of “growing” endoprosthesis (46). Individual rehabilitation course was performed in 43 (45.3%) children and resulted in increase of joint movement range, improvement of posture, and increase in muscular tension. Timely performed complex of rehabilitation measures enabled to correct sequelae of special treatment at early terms that significantly decreased disability of children, increases their social adaptation and quality of life.
