Overview
The purpose of this study is to create a systematic and general description of the surgical process for the direct anterior approach (DAA) in total hip arthroplasty (THA). For this purpose a surgical process model with a labeled dataset of THA surgery videos will be segmented into the individual surgical steps and sub-steps using a systematic approach.
Description
BACKGROUND AND PROJECT RATIONALE
In Total Hip Arthroplasty (THA), a degenerated hip joint is replaced with an artificial acetabular and femoral component. In clinical practice, several approaches to accessing bone anatomy are employed. The direct anterior approach (DAA) has been adopted widely in recent years due to smaller incisions, fewer complications, faster recovery, and improved patient outcomes. However, the reduced space and limited access may cause more complexity in the execution of surgical steps.
Primary objective
The first goal of this project is to create a systematic and general description of the surgical process for DAA in THA. For this purpose, surgical process models (SPMs) provide a basis to manage, organize, and optimize the surgical process. For this purpose, a labeled dataset of THA surgery videos will be segmented into individual surgical steps and sub-steps using a systematic approach. SPMs are a simplified network of surgical or surgery-related activities and their relationships. These models can be used to compare several interventions, surgeons, or whole Operating Room teams. In addition, the SPMs can be used as input for workflow management systems.
