[Total endoprosthetic hip replacement in patients with protrusive acetabulum bottom defect].

Total endoprosthetic hip replacement was performed in 39 patients with femoral head protrusion. The necessity of acetabulum defect infilling is proved. For the purpose of it the ground allobone transplant was impacted using the originally constructed impactor. The maximal volume of bone transplant was 170sm3. Reconstruction of the rotation center was achieved in 82% cases. 18% failed to reconstruct the anatomic rotation center, though without the significant limb contraction. The functional result was evaluated according to Harrison's scale after 6-48 months after the operation.87,2% of patients demonstrated good and 12,8% - satisfactory results in a 6 months period. There were no negative results in the group.
