Patient-Specific Surgical Guide for Total Hip Arthroplasty
In combination with the advancements of three-dimensional printing, a patient-specific surgical guide (PSG) for total hip arthroplasty (THA) is a convenient surgical instrument and has been implicated in the ideal positioning of the components, including acetabular and femoral components. PSG is designed and manufactured based on either preoperative computed tomography (CT) data or magnetic resonance imaging data. PSGs for THA are mainly classified into three types: PSG for guidewire insertion, PSG for bone cutting, and PSG for bone reaming and implant fixation. PSG positioning accuracy depends on the PSG design and contact area on the bone surface. PSGs for the acetabular component, for the conventional femoral component, and for the resurfacing femoral component have been clinically used. Based on the removal of soft tissues and preparation needed to confirm PSG setting, PSGs for THA do not always mean minimal invasive surgery.
