The major method of malignant bone tumors treatment is surgery. The most important task of an orthopedic surgeon is to preserve an adjacent joint. Currently, there are a large number of various reconstructive surgeries, including structural bone allograft, allocomposite and modular endoprosthetics replacement. The aim: to analyze the results of surgical treatment for proximal tibia malignant tumors using modular endoprosthesis. Materials and methods. The results of proximal tibia (PT) modular endoprosthetic replacement in 48 patients with PT tumor lesions were evaluated. The patients were divided into two groups: I (n = 36) – tumor resection and primary modular endoprosthesis, II (n = 12) – revision modular endoprosthetic replacement due to complications. Complications were divided into oncological, mechanical and non-mechanical. The functional outcomes were measured using the MSTS and TESS scores. Results. During the treatment, 10 (21.2 %) patients underwent myofascioplastic amputation at the middle third of the thigh: due to periprosthetic infection – 8 people and tumor recurrence – 2. It was found that the patients got back to regular way of life on average in 2.0–2.5 months. Functional results on the MSTS score were 73 ± 12 %, on the TESS score – 74 ± 16 %, which corresponds to good functional results. Among the patients, who underwent limb salvage surgery, no tumor recurrence was detected during a follow-up period from 6 months up to 11 years. Conclusions. The choice of surgical treatment depends on the size of tumor, its location, pathohistomorphological picture, age, presence of pathological fractures, vascular and nerve tumor invasion. The use of modern designs of PT modular tumor endoprostheses and perfect surgeries makes it possible to minimize complications.

There is increasing preference for limb salvage techniques in the management of pediatric musculo- skeletal tumors. This study was aimed at evaluating femoral growth following proximal tibia resection (PTR) and placement of an extendible endoprosthesis with sliding stem. This was a retrospective study. The demographic and clinical data were collected. All the patients with malignant tumors were fully staged and commenced on appropriate chemotherapy. An expected discrepancy of > 3cm was considered sub- stantial enough to warrant extendible prosthesis. Twelve patients who had follow up full length scanogram of the lower limbs were included for the evaluation of femoral growth. The last available scanograms were used for growth comparison of the femur. The age at resection for all twelve patients ranged from 4-13 years. The commonest histological diagnosis was Osteosarcoma. In the twelve patients assessed for the growth of femur, the mean femoral length was 96% [89%-102%] of the unaffected femur. Distal femoral physeal growth continued after im- plantation of a sliding extendible prosthesis after resection of proximal tibia tumors.
