Orthopaedic trainees performing elbow arthrocentesis found the lateral approach more successful and confidence-building than the posterior approach. Trainee experience level did not significantly impact the number of attempts needed for successful aspiration.

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.
