To investigate the safety of using the anterior approach (AA), compared to the lateral approach (LA), in hemiarthroplasty for the treatment of displaced neck of femur fractures.
Retrospective case-control match cohort study.
Level 1 trauma center.
Retrospective review of prospectively collected data for 39 consecutive intracapsular hip fractures treated with hemiarthroplasty using an AA between 2017 and 2021. Patients operated with the AA were matched in 1:2 ratio with patients that had hemiarthroplasty via a LA.
Discharge destination, 90-day emergency room (ER) visit or readmission rate, inpatient and 90-day mortality rate, inpatient medical complications, 90-day mechanical complications, 90-day reoperation, and length of hospital stay (LOS).
Discharge destination (p = 0.695), 90-day ER visit or readmission rate (p = 0.315), inpatient (p = 0.719) and 90-day mortality rate (p = 0.815), medical complications (p = 0.524), mechanical complications (p = 0.150) were similar between cohorts. Five patients, all in the LA-group, required re-operations within 90-days (p = 0.106). Patients in AA-group had shorter LOS (9.3 days, 95% CI [7.6-11.1] vs. 14.7 days [95% CI 12.2-17.3], p = 0.002).
The AA can be safely introduced for the treatment of hip fractures. Similar short-term outcomes relative to the LA were identified. The shorter LOS may reflect the improved early functional recovery offered from the muscle-sparing AA technique. Future, level-1 data should include early- and longer term functional outcome along with cost-effectiveness.
