About

Dr. Li Ya’s research bridges two distinct surgical frontiers: optimizing outcomes in total hip arthroplasty (THA) and advancing minimally invasive oncologic surgery. In orthopedics, Dr. Li developed and validated a novel mathematical algorithm that converts the sagittal functional safe zone for acetabular cup placement into the coronal plane. This work, published in 2022 and cited 23 times, directly addresses the challenge of predicting joint stability by relating ante-inclination to radiographic anteversion and inclination—a key contribution to the combined sagittal index. In gynecologic oncology, Dr. Li has pioneered robot-assisted techniques for fertility-sparing and radical cancer surgery. Notable contributions include the first detailed description of robot-assisted uterine artery-preserving radical trachelectomy (2024, 8 citations) and the introduction of robot-assisted Müllerian compartment resection for cervical cancer (2024, 7 citations), which aims to standardize radical hysterectomy by targeting the complete embryologic compartment. These works demonstrate Dr. Li’s dual impact: providing orthopedic surgeons with a precise, mathematically grounded tool for implant positioning, and offering gynecologic oncologists reproducible, nerve-sparing robotic approaches that preserve fertility while achieving oncologic clearance.
