Research models for reverse total shoulder arthroplasty (RTSA) are increasingly used but do not fully replicate in vivo conditions. Further development is needed to improve the accuracy and clinical reproducibility of these essential biomechanical models.

Area of Science:

Orthopedic Surgery
Biomechanical Engineering
Biomedical Simulation

Background:

Research models for reverse total shoulder arthroplasty (RTSA) have gained prominence over the last decade.
Current RTSA research models have limitations in fully replicating in vivo conditions.

Purpose of the Study:

To systematically review existing research models used for studying reverse total shoulder arthroplasty (RTSA).
To assess the ability of current models to reflect real-world biomechanical conditions.

Main Methods:

A systematic literature review was conducted using keywords related to RTSA and various research models.
Databases screened included Medline, Google Scholar, EMBASE, CINAHIL, and Ovid.
Articles detailing physical or virtual simulators replicating RTSA and the glenohumeral joint were included.

Keywords:

Main Results:

Computer and cadaveric models are the most prevalent and show reliability in simulating in vivo conditions.
Bone substitute models have been utilized in fewer studies.
Mechanical testing machines offer valuable insights into RTSA stability.

Conclusions:

Limitations exist for each individual RTSA research model.
Further research is necessary to develop advanced models that overcome current limitations.
Improved models can enhance the reproducibility of RTSA techniques in clinical practice.
