Transforaminal sacral approach for spinal anesthesia in orthopedic surgery: A novel approach.

Regional anesthesia is preferred world-wide for its distinct advantages. The benefits of regional anesthesia in patients with comorbid conditions are well-established. The administration of regional anesthesia can sometimes pose a challenge to the anesthesiologist due to the structural abnormalities of the spine. The most common difficulty encountered for spinal anesthesia in our hospital (Nalgonda District) is skeletal fluorosis. Apart from the midline approach, paramedian, and Taylor's approaches are advocated for difficult scenarios. This article reports two orthopedic cases, conducted under a novel spinal anesthesia technique, i.e., transforaminal sacral approach under C-arm guidance with a successful outcome. The sacral foraminal subarachnoid block is a method to access the subarachnoid space through the upper posterior sacral foramina.
