Introduction: There is evidence for use of cemented hemiarthroplasty resulting in greater anchoring and lesser peri prosthetic fracture. However, this procedure results in more haemodynamic instability and cardiopulmonary complications termed as ‘cement reaction’ or bone cement implantation syndrome. There has been a heightened interest among surgeons to compare cemented and uncemented hemiarthroplasty for fracture neck of femur.
Aim: To compare cemented and uncemented hemiarthroplasty in terms of blood loss during the procedure, post-operative complications, mortality, functional recovery and long term clinical outcome.
Materials and Methods: In a prospective study spanning 8 years from January 2006 to January 2014 in a tertiary care hospital, 52 cases of fracture of neck were selected. Twenty four patients underwent cemented and 28 patients underwent uncemented hemiarthroplasty. Mean follow up duration was 59.3 months. Harris Hip Score evaluation was done at each follow up. Radiological evaluation was done at each follow up for calcar length and periprosthetic fractures.
Results: Mean age of patients was 70 years. Harris Hip scores at 3, 6 and 12 months did not show statistically significant differences. Periprosthetic osteolysis or loosening was not seen in the present study. No complications noted in uncemented hemiarthroplasty. Four patients who had cemented hemiarthroplasty had infections. No mortality occurred during admission and within 12 months after surgery.
Conclusion: No significant difference was noted between the cemented and uncemented hemiarthroplasty procedures on long term follow up in terms of functionality. No re-operations and no mortality reported. Cemented hemiarthroplasty had more blood loss and minimal post-operative complications.
