Is there a learning curve preforming balloon kyphoplasty?

Area of Science:

• Spine surgery
• Minimally invasive procedures
• Surgical education

Background:

• Balloon Kyphoplasty (BKP) is a key minimally invasive treatment for vertebral fractures.
• The learning curve for BKP, impacting operative efficiency and safety, is not well-defined.

Purpose of the Study:

• To delineate the learning curve for Balloon Kyphoplasty (BKP).
• To analyze the impact of surgeon experience on operative time, radiation exposure, and Polymethylmethacrylate (PMMA) leakage.
• To hypothesize proficiency stabilization after 10-20 cases.

Main Methods:

• Retrospective cohort study of 194 patients undergoing BKP (2008-2020).
• Data collected included demographics, operative time, radiation dose, and PMMA leakage.
• Statistical analysis used t-tests, Chi-square, and logistic regression to assess surgeon experience impact.

Main Results:

• The learning curve for operative time in single-level BKP was modeled by a second-order polynomial, showing rapid improvement then plateauing.
• Radiation exposure demonstrated a slower learning curve, stabilizing around 100 cases.
• PMMA leakage rates remained consistent across surgeon experience levels.

Conclusions:

• Surgical proficiency in BKP is acquired relatively early, with technical skills stabilizing quickly.
• Optimizing radiation exposure in BKP necessitates continued practice beyond the initial learning phase.
• PMMA leakage incidence is independent of surgeon experience, indicating a balance between cement filling and leak occurrence.
