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

Recruiting

• Conditions: Hip Prosthesis
• Interventions: Other: Recording of total hip arthroplasty

• Registration Number: NCT05993845
• Lead Sponsor: Philipp Fürnstahl

Brief Summary

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.

Detailed 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.

Arm && Interventions

Group	Intervention	Description
Project population for total hip arthroplasty surgery recordings	Recording of total hip arthroplasty	We plan to record 60 total hip arthroplasty (THA) surgeries in the operating theatre performed by different surgeons of the hip team at Balgrist University Hospital or Kantonsspital Baden or Kantonsspital Winterthur, for data collection purposes.

Primary Outcome Measures

Name	Time	Method
labeled recordings of total hip arthroplasty	Up to 1 year	Surgery recordings of Total Hip Arthroplasties (THA) with Direct Anterior Approach (DAA) performed at Balgrist University Hospital will be used to develop an in-depth systematic analysis of surgical workflows and activity. The comparison and evaluation of THA with DAA performed at two external hospitals (Kantonsspital Baden, Switzerland and Kantonsspital Winterthur, Switzerland) will allow to generalize and evaluate the developed models: Multicenter study.
