Abstract
We present a match-paired study between computer-assisted and freehand techniques using a short modular femoral stem (Metha; B. Braun Aesculap, Tuttlingen, Germany) in total hip replacement (THR). Surgical time, clinical outcome, dislocation rate, limb length, and offset in 44 patients with ideal indication for this more conservative implant were assessed. Despite both longer surgical time and similar early outcomes, the results showed how computer-assisted techniques allow easier management of limb length discrepancy and offset restoring. We believe that navigated short modular stems are safe for less invasive THR.
