Hip endoprosthesis in Moldova, Eastern Europe
The doctors of international level of Medpark private hospital can perform all types of hip endoprosthesis, such as complete or partial prosthesis. During the intervention doctors use the most advanced prosthesis made of materials neutral to the body. The hip surgery is performed under general anesthesia. During the partial hip replacement, the surgeon removes the rounded head and the neck of the femur, which are replaced with a prosthesis. If the orthopedic surgeon performs a complete endoprosthesis, besides femur prosthesis, he replaces the entire articular surface. During the postoperative period patients are prescribed a complete rehabilitation course, in order to retake the normal way of life.

The closest, in terms of its technical solution, is the endoprosthesis of the proximal femur [3].

Extensive size options with 13 femur sizes and 11 tibia sizes;

Depending on the individual arrangement, the operation is conducted under general anaesthesia or spinal anaesthesia. Access to the affected joint is through an incision (about 15 cm) at the front of the knee. Removal of the destroyed joint surfaces using precision instruments is followed by fixing of the prosthesis components to the femur and the tibia. In line with the general research opinion and confirmed by our own experience, a replacement of the posterior surface of the patella is only considered if it is is severely damaged by arthrosis. The mobility of the artificial joint is tested, then the wound is closed layer by layer with the insertion of drainage tubes. After the operation, a control X-ray is taken.

Radiographs of 33 patients who had an expandable prosthesis inserted after tumor resection in the distal femur were evaluated. We hypothesized that, when a sleeve was present, there was greater stern migration and cortical reaction. The thickness of mediat and lateral cortices of the tibia was measured at 6 months and on the last follow-up radiograph. The distance from the edge Of the prosthesis to the cortical edge was also compared. When a sleeve was present, there was greater stern migration (P

Few studies have examined the impact of underlying diagnosis on the functional and oncologic outcomes following endoprosthetic proximal femur replacement (PFR). We performed a retrospective review of 61 consecutive cemented bipolar PFR in 59 patients for treatment neoplastic lesions with a minimum follow-up of 24 months. Twenty-two patients had primary bone tumors and 39 had metastatic disease. Average follow-up for the 30 surviving patients was 55.4 months and the mean postoperative survival for the 29 patients who died was 12.2 months. Patients with primary tumors demonstrated significantly better functional outcomes than those with metastatic disease, with mean Musculoskeletal Tumor Society functional scores of 80.2 and 66.8%, respectively (p = 0.0002). Age correlated inversely with functional scores (r = -0.48; p = 0.0002), while femoral resection length did not. Preoperative pathologic fracture did not appear to adversely impact final functional outcomes. The Kaplan-Meier 5-year implant survival estimate was 92.5%, with aseptic loosening as the endpoint. Both functional results and survival are increased for primary tumors versus metastatic disease following PFR. However, PFR results in excellent local disease control, reliable pain relief and good functional results in both groups, with prosthesis survival exceeding that of the patient in many cases.

The tumour was localised in the proximal femur in 44 patients, distal femur in 30 patients and proximal tibia in 16 patients. For reconstruction of the hip joint after proximal femur resection, we used the modular endoprostheses by Howmedica (KFTR, designed by Kotz) in 26 and modular revision endoprosthesis by W. Link or Lima-Lto (Revision system, designed by Wagner) in 18 patients. For knee joint reconstruction, we used only modular endoprostheses (Howmedica, KFTR designed by Kotz) in both distal femur and proximal tibia reconstruction.

Femur hip joint endoprosthesis, the curved shank (1) of which, is provided with a prosthesis collar (2) bearing on a bone surgical removal surface and comprising a grippable cone (3) carrying the attachable joint ball, a tightenable bolt (9) acting on the prosthesis as a tension strap traversing a lateral bore of the femur bone starting from the surgical removal surface and directed obliquely downwards and outwards, characterized in that an advantageously cylindrical ring (6) may be pushed on to the tapered pin (3) in a shape and force determined manner, which ring has a lateral surface-forming arm (7) extending over the prosthesis collar (2), the free extremity of which touching the surgical removal surface (5) has a bore (8) in alignment with the bone bore for passing throught by a tightenable bolt (9).
