Summary

Novice neurosurgeons show less precise fine motor control during simulated lumbar laminectomy, with more excessive movements and longer corrective eye fixations compared to experts. This highlights a need for improved microsurgical training protocols.

Area of Science:

  • Neurosurgery
  • Surgical Skill Assessment
  • Microsurgery

Background:

  • Lumbar laminectomy is a frequent neurosurgical procedure demanding precise power drill manipulation.
  • Assessing fine motor control in novice neurosurgeons is crucial for surgical training.

Purpose of the Study:

  • To compare the fine movement accuracy and eye movement patterns of novice and expert neurosurgeons during a simulated lumbar laminectomy task.
  • To identify specific areas of motor control and visual-eye coordination that differentiate novice from expert performance in microsurgery.

Main Methods:

  • Four expert and three novice neurosurgeons performed a simulated lumbar laminectomy on a 3D printed spine model.
  • Surgeons' drilling movements and eye movements were recorded using scene video and eye-tracking technology.
  • Statistical analysis using independent sample t-tests compared movement and fixation metrics between novice and expert groups.

Main Results:

  • No significant differences were observed in total fixation durations or pre-jump fixation durations between novice and expert surgeons.
  • Novice neurosurgeons exhibited a higher frequency of jumping events and greater jump distances during the drilling task.
  • Post-jump fixation durations were significantly longer in novice surgeons compared to experts, indicating more time spent on corrective eye movements.

Conclusions:

  • Distinct differences in movement accuracy and eye-tracking measures exist between novice and expert neurosurgeons in simulated microscopic lumbar laminectomy.
  • Understanding these differences in fine motor control and eye-hand coordination is vital for developing effective neurosurgical training programs.
  • Enhanced training protocols are needed to improve the microsurgical skills of surgical residents.
