title: Data from: Are multiple views superior to a single view when teaching hip surgery? a single-blinded randomized controlled trial of technical skill acquisition

description: Purpose: Surgical education videos currently all use a single point of
 view (POV) with the trainee locked onto a fixed viewpoint, which may not
 deliver sufficient information for complex procedures. We developed a
 novel multiple POV video system and evaluated its training outcome
 compared with traditional single POV. Methods: We filmed a hip resurfacing
 procedure performed by an expert attending using 8 cameras in theatre. 30
 medical students were randomly and equally allocated to learn the
 procedure using the multiple POV (experiment group [EG]) versus single POV
 system (control group [CG]). Participants advanced a pin into the femoral
 head as demonstrated in the video. We measured the drilling trajectories
 and compared it with pre-operative plan to evaluate distance of the pin
 insertion and angular deviations. Two orthopedic attendings expertly
 evaluated the participants' performance using a modified global
 rating scale (GRS). There was a pre-video knowledge test that was repeated
 post-simulation alongside a Likert-scale questionnaire. Results: The
 angular deviation of the pin in EG was significantly less by 29% compared
 to CG (p=0.037), with no significant difference in the entry point's
 distance between groups (p=0.204). The GRS scores for EG were higher than
 CG (p=0.046). There was a 32% higher overall knowledge test score
 (p&lt;0.001) and 21% improved Likert-scale questionnaire score
 (p=0.002) after video-learning in EG than CG, albeit no significant
 difference in the knowledge test score before video-learning (p=0.721).
 Conclusion: The novel multiple POV provided significant objective and
 subjective advantages over single POV for acquisition of technical skills
 in hip surgery.

 the videos used in the article "Are multiple views superior to a
 single view when teaching hip surgery? A single-blinded randomized
 controlled trial of technical skill acquisition". Two sequences are
 present, the dry bone sequence and the surgery sequence. The dry bone
 sequence’s filenames begin with “drybone_cam” and the surgery sequence’s
 filenames begin with “surgery_cam”. There are 7 videos for the dry bone
 sequence and 8 videos for the surgery sequence. Each video represents a
 different point of view of the sequence. The videos have a size of
 1440x810 pixels. The codec for the video is MP4 and there are 25 frames
 per second. The audio codec is AAC at 48 kHz.drybone_cam1Video of the camera 1 for the dry bone sequencedrybone_cam2Video of the camera 2 for the dry bone sequencedrybone_cam3Video of the camera 3 for the dry bone sequencedrybone_cam4Video of the camera 4 for the dry bone sequencedrybone_cam5Video of the camera 5 for the dry bone sequencedrybone_cam6Video of the camera 6 for the dry bone sequencedrybone_cam7Video of the camera 7 for the dry bone sequencesurgery_cam1Video of the camera 1 for the surgery sequencesurgery_cam2Video of the camera 2 for the surgery sequencesurgery_cam3Video of the camera 3 for the surgery sequencesurgery_cam4Video of the camera 4 for the surgery sequencesurgery_cam5Video of the camera 5 for the surgery sequencesurgery_cam6Video of the camera 6 for the surgery sequencesurgery_cam7Video of the camera 7 for the surgery sequencesurgery_cam8Video of the camera 8 for the surgery sequence
