BACKGROUND Outcome data on two-stage revision surgery for deep infection after septic hip arthritis are limited and inconsistent. This study presents the medium-term results of a new, standardized two-stage arthroplasty with preformed hip spacers and cementless implants in a consecutive series of adult patients with septic arthritis of the hip treated according to a same protocol. METHODS Nin...

Introduction: Recently the most accurate diagnostic method in the diagnosis of prosthesis infection is the combination of Tc-99m labeled leukocyte/bone marrow imaging. However the diagnostic efficiency of the test is influenced because of its low spatial resolution. Recently SPECT/CT imaging is implicated in this test with efficient additional diagnostic improvement. In the dep...

Cement restriction and pressurisation are helpful technical points in achieving a good cement mantle in cemented hip replacement. In this prospective study, we compared 39 cases where a Hardinge polyethylene restrictor was used and 33 cases where a bone block restrictor was used during Charnley hip replacement. The preoperative radiographs were templated, calibrated holders for the cement restr...

The adaptive bone remodeling phenomenon in the femur before and after prosthetic total hip joint replacement (THR) was investigated using the three dimensional finite element method. A normal hip joint model which composed of the proximal femur and the pelvic bone including femoral head and acetabular was constructed three-dimensionally by our method reported previously. The simulation model wa...

Massive osteolysis and granulomatous pseudotumor tissue reactions are long-term complications of total hip replacement. It is a condition of localized bone resorption in contact with prosthetic material. It is speculated to be a consequence of metal hypersensitivity or inflammatory reaction to excessive wear. Ten years after total cementless hip replacement (metal on polyethylene surface), a 70...

Total hip and knee arthroplasties have been 2 extremely successful surgeries with respect to providing pain relief and increasing mobility. The number of primary and revision total hip arthroplasties continues to increase, and with this, the incidence of periprosthetic fractures continues to rise. Periprosthetic fractures around total hip and knee arthroplasties can prove to be a particularly c...

The Birmingham mid head resection (BMHR) arthroplasty can be used as an alternative to conventional stemmed total hip arthroplasty in young patients unsuitable for hip resurfacing. This study investigated the effect of stem size on femoral neck fracture in the BMHR. Sawbones composite femurs were randomly allocated to one of the following groups: (1) unprepared femur with no prosthesis, (2) fem...
