Abstract
Objective The aim of the present study was to compare functional results after Cemented Calcar
replacement vis-a-vis Long stem Cemented hemiarthroplasty in patients aged more than
80 years with unstable intertrochanteric fractures.
Methods The present prospective, randomized trial included 140 patients with AO/OTA type
31-A2, A3 intertrochanteric femur fracture, randomized into 2 treatment groups and
followed-up for a minimum of 2 years. Sixty-seven patients in group A were treated
with a cemented calcar replacing prosthesis, and 65 patients in group B were treated
with a cemented long stem femoral stem prosthesis. The primary end points were hip
functions at 2 years. The secondary end points were the complications encountered,
mortality, surgical time, reoperation, blood loss, and activities of daily living.
Results There were no major differences between the groups in terms of hip function, quality
of life (health related), reoperation, mortality, and blood loss. However, the function
in hip joint and activities of daily living deteriorated in both groups in comparison
with prefracture levels.
Conclusion In octogenarians with an unstable intertrochanteric fracture, cemented calcar replacing
prosthesis has similar clinical results in comparison with long stem cemented hemiarthroplasty.
Hemiarthroplasty with either implant is a good option in this subset of patients.
