Similar recovery in mobility and quality of life after cemented and cementless hemiarthroplasty for hip fractures

Abstract

Summary: Patients who suffer hip fractures become immobile with reduced quality of life. Our study aims to assess which cemented or cementless hemiarthroplasty resulted in better mobility or quality-of-life scores. Our retrospective review showed that both have similar scores after matching for age, gender, body mass index and comorbidities. Introduction: Hip fractures have mortality rates of up to 10% at 1 month and 30% at 1 year, as well as significant morbidity. This paper seeks to compare mobility and quality-of-life scores of cemented against uncemented hemiarthroplasty for the displaced neck of femur fractures. Our hypothesis is that there is no difference between the mobility and quality of life of patients treated with cemented or uncemented bipolar hemiarthroplasty. Methods: A retrospective review of registry data on hemiarthroplasties performed in our institution between 2011 and 2019 was conducted. From this dataset, 70 cemented hemiarthroplasties and 238 uncemented hemiarthroplasties were identified. Patients were assessed pre- and post-operatively, at 6 weeks, 3 months, 6 months and 12 months to determine functional recovery through mobility and quality-of-life scores. Results: On propensity score matching, both groups showed a reduction in Parker mobility score from 6.5 to 4 ( p = 0.91), SF-36 physical function scores from 52.5 (cemented) to 30 and 57.5 (uncemented) to 25 ( p = 0.79). Comparing the delta changes from pre-fall after matching, no significant differences were observed. From the analysis of the matched set of data, treatment of neck of femur using cemented or non-cemented bipolar hip prosthesis resulted in similar mobility and quality-of-life scores. Conclusion: In our analysis, there was no statistically significant difference in the mobility or quality-of-life scores of the patients undergoing cemented versus uncemented hemiarthroplasty for the displaced neck of femur fractures.
