Cannulated interlocking titanium prosthesis in pathological proximal femoral fractures: a prospective study

The surgical management of metastatic lesions of proximal femur poses a challenge to the surgeon. Internal fixation procedures may not be feasible due to the location and size of the lesion and long stem endoprosthetic replacement may be a safer and preferred option. Bone cement though ideal may not be desirable in high risk patients. Un-cemented cannulated intramedullary prosthesis combines the principles of hemiarthroplasty and an interlocking intramedullary fixation. The prosthesis was used in 10 consecutive patients with 10 completed and 2 impending fractures of proximal femur with a disease free acetabulum. Surgical revision was considered the end point of the study. Pain free, full weight bearing mobilisation was possible in eight patients and no patient required revision until their death. The prosthesis provided a satisfactory solution with minimum surgical complications in high risk patients in our study.
