Automated Impaction Improves Femoral Component Canal Fit in Total Hip Arthroplasty: A Matched Study.

ABSTRACT:

Background

Automated impaction in total hip arthroplasty (THA) is a new technology in femoral canal preparation. Recent studies have shown that it improves component alignment and fit and reduces operative time. The purpose of our study is to further investigate this technology's impact on femoral component canal fit, fracture risk, and operative time.

Methods

We conducted a retrospective, matched analysis of 274 patients who underwent THA via automated impaction (N = 137) or manual impaction (N = 137). Postoperative radiographs were assessed to measure canal fill (CF) at the level of the neck cut, the lesser trochanter (LT), and 10 mm above (LT+10) and 60 mm below (LT-60) the LT. The average CF across these measurement points was calculated. The incidence of intraoperative
