BACKGROUND The number of patients undergoing hip arthroplasty revision is constantly growing. Especially, complex problem is extensive loss of bone stock and pelvic discontinuity that requires reconstruction. CASE REPORT The paper presented a 50-year old patient, who ten years ago underwent a total cement artrhroplasty of the left hip. A year after the primary operation the patient had diffic...

1 Previously published in Orthopadie Technik, 4/76, 58-60. Introduction M o r e than twenty years ago, McLaur in (1954) published his first report on the Canadian hip disarticulation prosthesis. His work was aimed at improving the conventional design of the saucer-type and tilting table prostheses. A measure of his success can be seen in that the Canadian-type has made the other two almost obso...

Modular neck hip prosthesis born in the 1990 with the aim of allowing the surgeon to modify CCD angle, offset and femoral anteversion intra-operatively restoring patient's original biomechanics. In order to achieve the best biomechanics of the reconstructed hip, preoperative planning is essential. In the last few years modularity has been questioned and an argument made for the return to mono b...

Postoperative hip alignment was studied on radiographs in cases of total hip arthroplasty (THA) and of Bipolar Head Prosthesis(BHP), both with MX-1. Postoperative anteroposterior-view radiographs of hip joints of patients with a normal hip joint on the unoperated side and without pelvic tilt were used. Thirty-nine THA patients (femoral neck fracture), 26 THA patients (osteonecrosis of the femor...

In 1946, the Judet brothers performed their first ‘resectionreconstruction’ of the femoral head (Judet 1947) using a prosthesis made entirely of polymethylmethacrylate (PMM.A). The early implants broke frequently and were later reinforced by a steel rod (Judet and Judet 1950). Failures continued, however, and use of the prosthesis was abandoned decades ago. Case report. In 1952, a 12-year-old g...

Background: Cementless hip prosthesis was designed to provide biologic fixation, without the use of cement. The second generation components have shown more reliable bone ingrowths and survival rates. We are reporting a midterm result of two designs of cementless prosthesis in a unique culture with different social habits and expectations.Methods: 52 primary cementless total hip arthroplasty in...

BACKGROUND Treatment of the sequelae of congenital high luxation of the hip joint is a major challenge in prosthetic surgery, demanding from the operator thorough familiarity with the problem and experience in hop reconstructive surgery. MATERIAL AND METHOD The results of 4 years observation, of the treatment of 14 woman in the average age of 38 years old with 18 hip joints with congenital hi...

INTRODUCTION Stress-shielding following uncemented hip replacement causes bone remodelling due to alteration of the load transfer pathways. The degree of bone resorption is related to the geometry and bending stiffness of the stem. Large diameter, cobalt chrome stems are attributed with producing the most pronounced bone loss. The Epoch hip prosthesis (Zimmer Inc., Warsaw, IN) is a low bending ...

Vascular trauma after hip surgery has been described mostly after elective total hip arthroplast)~ but there have also been a number of cases after hip fracture surgery. Re-operation increases this risk in elective total hip arthroplastyJ Arterial injury complicating hip replacements are rare 2 and usually occur at the time of operation. Delayed arterial injury may result from a false aneurysm ...
