Purpose
To investigate patient-specific factors that predict Total Hip Replacement (THR) in patients with fracture neck of femur (NOF), fulfilling the National Institute of Health and Care Excellence (NICE) criteria.
Methods
Hip fracture database from a district general hospital and university hospital was retrospectively reviewed to identify patients fulfilling NICE criteria for THR after fracture NOF. Patient demographics, Nottingham Hip Fracture score (NHFS), complications, re-operations, revision, 30 days and one-year mortality was obtained from patient-records. Independent predictors correlating with the outcome of surgery were identified. A logistic regression analysis was used to predict the type of surgery in these patients.
Results
A total of 230 (114 WMH and 116 MH) were identified; 133 (57.8 per-cent) received hip hemiarthroplasty (HA), and 97 (42.2 per-cent) received THR. Patients receiving THR (mean 73.5 years, 95% CI 72–74.8) were significantly younger in comparison to patients receiving HA (mean 81.7 years, 95% CI 80.5–82.8). A negative correlation is noted between NHFS and type of surgery (Pearson’s correlation − 0.537, p < 0.01), implying higher NHFS decreased the likelihood of receiving THR. Regression analysis showed NHFS (p-0.001) and walking ability (p-0.001) as significant predictors for the type of surgery (Nagelkerke R2-0.472). A log-rank test showed higher estimated survival time in patients with THR in comparison to HA (p-value 0.002).
Conclusions
NHFS and walking ability can be used as an adjunct to the NICE criteria for selecting patients for THR after fracture NOF. Carefully selected patients treated with THR survive longer and have a better outcome in comparison to HA.
