Measuring outcomes comparing total hip arthroplasty and hemiarthroplasty using oxford hip score in neck of femur fractures in 60-80 year olds - retrospective study.

Abstract

The Oxford Hip Score (OHS) is a 12-item, self-administered questionnaire focused on the hip. Because of its validity, responsiveness, and reliability, it has been widely used as a primary outcome measure for THA and hip arthritis. This study employs the Oxford Hip Score questionnaire to compare the outcomes between people who had total hip replacement and those who had hemiarthroplasty between the ages of 60 and 80. A retrospective investigation was conducted at Lister Hospital. Patients (aged 60 to 80) who were hospitalized between January 1, 2020 and July 31, 2022 who had intracapsular neck of femur fractures were included. Patients were contacted again in August 2025, three years later. The study excluded patients who did not have hemiarthroplasty (HA) or total hip arthroplasty (THA). The study's primary purpose was to compare the outcomes of patients treated with a THA to those treated with a HA. The Oxford Hip Score was used to determine the outcome. The statistical analysis was conducted using the IBM SPSS program version 22.0 (SPSS, USA). Our findings revealed that females were operated on more than males in both categories. The HA group had a greater average age at admission than the THA group (74.44 vs 70.32), p-value 0.002. THA had a higher pre-op AMT and a lower post-operative 4AT score than HA. The mean time from admission to surgery was similar, although HA had a shorter mean operating time. The THA group stayed in the hospital for a shorter period of time, whereas the THA group had more patients who were freely mobile before and after surgery.The study found that both groups had a mean Oxford score indicating mild to moderate pain and impaired mobility at follow-up, THA having a mean 38,69, SD 12.192, 95 % CI 34.05-343.33 vs HA mean 37.81, SD 11.588, 95 % CI 33.88-41.73, p-value 0.766. THA had greater scores in patients' capacity to wash and dry themselves, get into mode of transportation, walk longer, climb stairs, and had less pain. All of the results were not statistically significant. Our findings reveal that both THA and HA have scores that identify individuals with mild to moderate impairment with regards to mobility, regardless of the surgery they underwent following an acute neck of femur fracture. The data, however, did not reveal if there was a change before and after surgery, and the Oxford hip score is based on patient perceptions. THA required a shorter hospital stay but a longer operation. This study can serve as a foundation for future prospective studies with higher sample sizes.
