Abstract
Recently in traumatology various methods of impregnation biodegradable implants and allografts with antibiotics are widely used. Among them the soaking, shaking and ionophores are common used. We aimed to choose the optimal method of impregnation with the antibiotic of the head of the femur, taken from patients after arthroplasty. We studied 6 femoral heads after hip replacement. Head №1 the iohexol (Omnipaque) was injected through circular ligament and through the neck of the femur. Head №2 through the circular ligament, head №3 through the neck of the femur, head №4 through the circular ligament and through the neck of the femur, head №5 through 4 pre-drilled channels a brilliant green solution was injected. The head №6 was soaked in a brilliant green solution. Head №1 assessed by radiology. All the heads, treated with brilliant green, were cut in half to assess the degree of impregnation. On the X-ray image of head №1 the contrast agent has spread enough. In osteotomy, the impregnation with brilliant green head №2, №3, №4, №5 was seen in 3–4 mm around the needle passage place. Head №6 the bone was not impregnated. Despite the fact that the radiograph showed a sufficient spread of contrast agent, on the sections of the head, treated with brilliant green, showed the spread of liquid 3–4 mm around the needle passage place. This indicates that the impregnation of large bone is not effective.
