Tibial condyle fracture is an intra-articular fracture. In treating central depression fracture or sprit depression fracture, it is necessary to raise the cartilage in the depressed part and to fill the resulting bone defect.In the present study, we used hydroxyapatite granules (bone ceram) to fill bone defects in treating tibial condyle fractures, and obtained satisfactory results.The subjects were nine patients with reratively good ADL treated in our hospital between 1994 and 1997. Their ages at the time of injury varied from 68 to 93 years, with a mean age of 74.4 years, and they included three men and six women.For surgery, AO L-shaped buttress plates were used in four patients and MAY anatomical bone plates were used in five as materials for internal fixation of the fractures, and a mean of 7g of hydroxyapatite was used per patient to fill bone defects.During follow-up, articular surface depression improved from a mean of 12.9 to 1.9mm on radiographic images.Further, both the range of motion of the knee joint and ADL returned nearly to the levels present before fracture for all 9 patients.Hydroxyapatite exhibits good bioaffinity and strength and is considered useful for treating fractures in aged patients, in whom sampling of autologous bone is difficult.
