Hip Surgery Training Video Efficacy Data from Randomized Controlled Trial

A 2020 study by Huixiang Wang compared multiple-viewpoint versus single-viewpoint video training for hip resurfacing surgery. The dataset contains results from 30 medical students, measuring pin trajectory deviations, Global Rating Scale scores, and pre/post knowledge test results. It provides objective metrics on the efficacy of a novel multi-camera surgical training system.

Use Cases

• Analyze the correlation between angular deviation of the pin insertion and Global Rating Scale (GRS) scores to validate skill assessment metrics.
• Compare pre-video and post-video knowledge test scores between experimental and control groups to measure learning gains.
• Evaluate Likert-scale questionnaire responses against objective performance measures like entry point distance for subjective feedback validation.
• Model the impact of training group (multiple vs. single POV) on pin trajectory deviations and GRS scores using the data from 30 participants.

Strengths

• Data originates from a single-blinded randomized controlled trial, a robust experimental design.
• Includes 30 participant records with multiple objective (angular deviation, distance) and subjective (GRS, Likert-scale) performance measures.
• Results show statistically significant differences (e.g., 29% less angular deviation) supporting clear conclusions.

Limitations

• Small sample size of 30 medical students limits statistical power and generalizability to broader trainee populations.
• Focus on a single surgical procedure (hip resurfacing) may not reflect training efficacy for other operations.
• Data is from a single study conducted at one institution, potentially introducing institutional bias.
