About

Steven M. Tommasini is an orthopedic researcher specializing in computer-assisted surgical planning and biomechanical simulation for total hip arthroplasty (THA). His work sits at the intersection of surgical technique, implant optimization, and three-dimensional modeling, with a particular focus on improving postoperative outcomes and reducing complications such as dislocation and impingement. Tommasini's most significant contributions center on leveraging advanced 3D preoperative planning software to simulate a broader range of daily living movements than traditional protocols allow, pushing the field beyond conventional two-position assessments. His 2023 study on simulating movements of daily living — his most cited work with 8 citations — demonstrated how comprehensive motion modeling can enhance prosthetic stability planning. Subsequent research has challenged prevailing clinical assumptions, notably showing that certain offset restoration strategies can paradoxically reduce range of motion, and that hip abduction may serve as a sufficient standalone posterior precaution following posterior approach THA with large femoral heads. With a focused body of work accumulating 17 citations across just two years, Tommasini is emerging as a rigorous voice in evidence-based implant selection and surgical planning, offering clinically actionable insights that directly inform how surgeons prepare for and execute total hip replacement procedures.
