Puncture and localization for percutaneous endoscopic lumbar discectomy with C-arm navigation: a randomized controlled cadaver trial.

ABSTRACT:

Background

Accurate preoperative puncture and localization is a key step in percutaneous endoscopic lumbar discectomy (PELD). This study investigated the benefit of puncture and localization for PELD by C-arm navigation over conventional methods.

Methods

Sixteen adult cadavers were randomly divided into two groups (group A defined as the C-arm navigation method, and group B defined as the conventional localization method). Two junior orthopedic surgeons who specialized in spinal surgeries were randomly allocated to each group. Conventional localization using C-arm fluoroscopy and localization using C-arm navigation were performed during the procedure. The intervertebral foramen on both sides at L3-L4, L4-L5, and L5-S1 levels were punctured using the two methods. Technical pa
