Functional Outcome of Bipolar Hemiarthroplasty by Using Hip Harris Score (HHS) in Fractures of Neck of Femur
Objective: To determine the functional outcome of bipolar hemiarthroplasty by using Hip Harris score (HHS) in femoral neck fractures
Methodology: Thiscross-sectional study was done at the Orthopaedics department of Dr. Ruth K. M. Pfau, Civil Hospital Karachi, Pakistan between March 2019 to March 2020. All patients who were scheduled to have bipolar hemiarthroplasty for femoral neck fractures were included in the study. Cannulated screws fixation was applied in un-displaced femoral neck fractures percutaneously with minimal invasive procedure means through small incision with the help of guide pin, image intensifier. Post OP check x-ray was taken to see reduction and screws fixation, neck fracture and placement of implant. Functional outcome was assessed using Hip Harris Score (HHS) by checking the degree of movement of the hip in addition to the radiological assessment of union by the 8th week postoperatively. Data was analyzed using Statistical Package for Social Sciences (SPSS, IBM, version 26).
Results: A total of 259 patients were included in the study with a mean age of 68.7±7.2years. The mean ± SD of pre and postoperative Hip Harris Score was noted as (89.3±9.2 v/s 97.7±9.6; P<0.01). Out of 259
patients, 69 (26.65%) were male. Poor functional outcome was noted in 22 (8.5%) patients, while fair, good, and excellent functional outcome was noted in 51 (19.7%), 60 (23.2%) and 126 (48.6%) patients respectively. Satisfactory functional outcome was noted in 186 (71.8%) patients.
Conclusion: The findings of this study indicate that highly significant difference was noted between pre and postoperative Hip Harris Score. So, findings of this study support the idea that bipolar hemiarthroplasty is an effective treatment modality for the management of elderly patients with displaced femoral neck fractures.
