A MODIFIED TECHNIQUE FOR CLOSED REDUCTION OF MODULAR HIP PROSTHESIS DISLOCATION: BASSI’S METHOD

Abstract

Dislocation is one of the common complications after hip arthroplasty. The problem is further compounded in modular hip prosthesis as there is potential risk of disengagement of the components. A different technique for closed reduction of the dislocated modular hip prosthesis is described. The manoeuvre involves flexion, adduction and internal rotation of femur in lateral position to relocate the head of the prosthesis in the cup. This manoeuvre avoids contact between the head of the femoral component and edge of the acetabulum and thus reduces the potential risk of disengagement of the components of modular hip prosthesis. This method is effective and efficient for reduction of total and partial modular hip arthroplasty and may be performed without anaesthesia.
