ABSTRACT: Background
During manual broaching (MB) in total hip arthroplasty (THA), off-axis forces delivered to the proximal femur and broach malalignment can lead to fractures and cortical perforations. Powered broaching (PB) is a novel alternative that delivers consistent impaction forces and reduces workload. This is the first large-scale study to compare intraoperative and 90-day rates of periprosthetic femur fractures (PFFs) and perforations in THA performed using MB vs PB.Methods
Our institutional database was reviewed for all patients undergoing primary cementless direct anterior THA from 2016 to 2021. Three surgeons performing 2048 THAs (MB = 800; PB = 1248) using the same stem design were included. PFFs and perforations within 90 days of the index procedure were compared. Differences in length of surgery and demographics were assessed.Results
Calcar fractures occurred in <1% of patients (PB [0.96%, 12/1248] vs MB [0.25%, 2/800]; P = .06). Rates of trochanteric fractures did not differ (PB = 0.32% [4/1248] vs MB = 0.38% [3/800]; P = .84). Cortical perforations occurred in 0.24% (3/1248) of the PB cohort and in 0.75% (6/800) of the MB cohort (P = .09). No revisions due to aseptic loosening or PFF occurred within 120 days of surgery.Conclusions
Our single-center experience with powered femoral broaching in THA demonstrates PB is a safe and efficient means of performing direct anterior THA. Low rates (<1%) of PFF, perforation, and revision can be achieved. Given our positive experience with PB, all surgeon authors utilize PB nearly exclusively for elective primary direct anterior THA.
