Study design: Retrospective cohort. Objective: To determine if intraoperative on-table lumbar lordosis and segmental lordosis coincide with perioperative change in lordosis. Summary of background data: Improvements in sagittal alignment are…
Study design: Retrospective cohort comparison study. Objective: To compare perioperative outcomes, radiographic parameters, and patient reported outcome measures (PROMs) between minimally invasive unilateral laminotomy with bilateral decompression (MIS-ULBD) versus MIS…
Study design: Single-center, multi-surgeon, retrospective review. Objective: Evaluate the timing of return to commonly performed activities following minimally invasive spine surgery. Identify preoperative factors associated with these outcomes. Summary of…
Objective: Synthetic hydroxyapatite (HA) and its related materials have made great progress in basic research and clinical application in spinal repair and reconstruction. However, the effect of HA and its…
Background: The effect of prolonged symptom duration in patients undergoing ambulatory MIS-TLIF on postoperative clinical outcomes has not been well studied. We aim to compare symptom duration of pain and/or…
Background: Traditional open posterior fusion techniques involve stripping of the posterior paraspinal muscles with protracted retraction, which can lead to ischemia and denervation. This may result in poor clinical outcomes…
Background: Liposomal bupivacaine (LB) is a local analgesic that may be used at the time of surgery to limit postoperative pain around the surgical site. Its efficacy in decreasing pain,…
Introduction: Unilateral biportal endoscopy (UBE) is a relatively new yet common minimally invasive procedure in spine surgery, capable of achieving adequate decompression for lumbar spinal stenosis through unilateral laminectomy bilateral…
Background: Clinically, there are substantive practice variations in surgical management of degenerative lumbar spondylolisthesis. We aimed at evaluating whether decompression alone outcomes for patients with degenerative lumbar spondylolisthesis are comparable…
Background: Ceruminous glands are modified apocrine glands of the external auditory canal (EAC). Malignant tumours within the ceruminous glands are extremely rare, and the most common histological type is adenoid…
