Orthopaedic Trainee Confidence in Elbow Arthrocentesis Using a Cadaveric Elbow Effusion Training Model

Area of Science:

• Orthopaedic Surgery
• Medical Education
• Diagnostic Procedures

Background:

• Elbow arthrocentesis is crucial for diagnosing joint pathologies.
• While minimally invasive, it carries risks and has a learning curve.
• Understanding trainee performance across different experience levels is essential.

Purpose of the Study:

• To compare orthopaedic trainee confidence and success rates in elbow arthrocentesis.
• To evaluate performance differences between lateral and posterior approaches.
• To assess the impact of training level on procedural outcomes.

Main Methods:

• Utilized ten fresh-frozen cadaveric specimens for simulated elbow arthrocentesis.
• Assigned specimens to senior residents, junior residents, and interns.
• Recorded confidence levels and number of attempts for lateral and posterior approaches using contrast and dye.

Main Results:

• The lateral approach required significantly fewer attempts (1.3) than the posterior approach (2.7).
• Trainees reported higher confidence with the lateral approach compared to the posterior approach.
• Confidence levels varied by training level, with interns less confident than seniors and juniors.

Conclusions:

• Procedural confidence is influenced by trainee experience and approach familiarity.
• Successful aspiration rates depend on the approach, not the trainee's experience level.
• Findings offer insights for optimizing elbow arthrocentesis training in orthopaedics.
