Evaluation of Results and Functional Outcome of Modular Bipolar Hemiarthroplasty in Fracture Neck of Femur in a Kashmiri Population

Abstract

BACKGROUND: Femoral neck fractures are a very common occurrence in orthopedic trauma, with females outnumbering males, minor trauma (Fall ) was a major causative factor. There is a growing debate on the management of such fractures in elderly patients. Hemiarthroplasty using modular bipolar prosthesis for displaced femoral neck fractures in the elderly provides freedom from pain, better range of movement, and more rapid return to unassisted activity with an acceptable complication rate.

AIMS & OBJECTIVES: To evaluate results and functional outcome of modular bipolar uncemented hemiarthroplasty in fracture neck of femur in a Kashmiri population

STUDY DESIGN: Prospective observational study.
PARTICIPANTS: 30 patients with fractured neck of femur meeting the inclusion criteria.
METHODS: After seeking approval from Institutional Ethical Committee, this study was conducted on patients admitted with fractured neck of the femur at SKIMS Medical College Hospital Bemina, Srinagar from February 2019 to June 2020. Informed and written consent was obtained from all the patients in the Urdu language. The functional outcome was assessed at 6 months follow up using validated hip score, viz Modified Harris Hip Score.
RESULTS: Based on the modified Harris hip score, 14 patients (46.7%) had excellent functional outcomes while 12 patients (40 %) had a good outcome. The remaining 2 patients (6.7 %) had a fair outcome and 2 (6.7 %) patients had a poor outcome.
CONCLUSION: Hemiarthroplasty using modular bipolar prosthesis for displaced femoral neck fractures in the elderly provides freedom from pain, better range of movement, and more rapid return to unassisted activity with an acceptable complication rate.
IMPLICATIONS: Hemiarthroplasty can be cemented or uncemented. We used an uncemented prosthesis in our study which provides evidence that this is a suitable treatment option in fracture neck of femur in elderly
