Modeling and Workflow Recognition for the Anterior Approach in Total Hip Arthroplasty

"We record total hip arthroplasties (THA) of hip surgeons at Balgrist University Hospital (BUH), Kantonsspital Baden (KSB), Kantonsspital Winterthur (KSW). Video \& audio data are stored locally at Balgrist-managed servers (patient-sensitive information removed).~Data includes:~Demographics (year of birth, sex, smoking status, body mass index) Diagnosis Surgery-specific data \& other surgical procedures during recording Standard preoperative Computed tomography of the hip/pelvis Standard pelvis x-rays pre- \& postoperative Standard axial hip x-rays pre- \& postoperative Western Ontario \& McMaster Universities Osteoarthritis Index \& Harris-Hip-Score To ensure the generated Surgical process model(SPM), evaluated using the recordings obtained from surgeries performed at BUH, generally describes the surgical process of THA, we apply our model to surgeries from the KSB and the KSW. There, 3 THAs are recorded and analyzed regarding commonalities and discrepancies in the SPM."
