Background : The consensus of treating a transcervical fracture neck femur in elderly is on replacement surgery. A total arthroplasty is not always the answer especially in patients where stability and mobility need to be balanced especially in patients who cannot comprehend the required changes in the life style &restriction in activity. The traditional method would be a hemiarthroplasty with Austin Moore′s or Thompsons prosthesis. Both are in the long term associated with loosening, acetabular erosion, pain and loss of mobility. Method : The present study involves 106 patients who underwent 108 surgeries with a hybrid system of Charnley stems and Hastings bipolar shells, for transcervical fracture neck femurs. Results : Over all 78% had excellent to good results at three-year follow up. Conclusion : The advantage of the system is in the modularity obtained from the different sized Charnley stems, Hasting shell which are available in increments of 1mm allow exact matching of the head and the ease with which the system can be converted to Charnleys low friction Arthroplasty without replacing the stems.
