BACKGROUND: Lumbar herniated disc is a "preference-sensitive" condition, in which the optimal treatment choice is crucially dependent on an informed patient's goals and values. Little is known about decisional conflict, defined as an individual's level of uncertainty regarding a decision, in patients considering treatment for lumbar herniated discs. Our work aims to identify factors associated with decisional conflict and areas for improved shared decision-making. METHODS: We prospectively surveyed patients seeking treatment for a lumbar herniated disc at L4-L5 and/or L5-S1 with a physician at the UCLA Spine Center...

Stephan Klessinger
OBJECTIVE: Percutaneous disc nucleoplasty (PDN) is a minimally invasive technique. A portion of the nucleus tissue is ablated using the Coblation technique. Re-surgery is an important factor for the clinical outcome. However, the rate of subsequent surgery after PDN is still unknown. The aim of the present study was to investigate the frequency of an additional open surgery after PDN in a retrospective of more than ten years. PATIENTS AND METHODS: Retrospective observational study...

RATIONALE: CRPS after a lumbar surgery has symptoms that are similar to PSSS. However, standard criteria for distinguishing CRPS from PSSS do not exist. We present a case report of a 31-year-old female with CRPS symptoms after lumbar spinal surgery treated by performing SELD. PATIENT CONCERNS: This patient was referred to our pain clinic for left ankle pain. She received a lumbar discectomy for a herniated lumbar disc (L5/S1) but the pain was aggravated after surgery...

Endplate pathology plays an important role in the development of lumbar disc degeneration. Previous research paid little attention to differences between the superior and inferior endplates as a possible risk factor for disc degeneration. The purpose of this study was to test the hypothesis that asymmetry between the superior and inferior endplates is a risk factor for the development of lumbar disc degeneration. A total of 134 patients with lumbar disc herniation(LDH) and100 healthy adults('Controls') underwent magnetic resonance imaging scans...

OBJECTIVE: Preserving the ligamentum flavum (LF) during lumbar spine surgery can help to limit the extent of postoperative epidural fibrosis (EF), which is a potential cause of persistent leg pain. We present a retrospective analysis of microdiscectomy with preservation of the LF to evaluate the effects of the two LF mobilizing techniques (reflecting inferiorly or medially vs. removing completely) on EF and clinical outcomes. METHODS: Microdiscectomy was performed through a unilateral laminotomy in 93 patients (52 male, 41 female; mean age, 46 years; range, 25-65 years) with L3-L4 (n = 3), L4-L5 (n = 40), and L5-S1 (n = 50) lumbar disc herniation...

Low back pain is a significant socioeconomic burden in the United States and lumbar intervertebral disc degeneration is frequently implicated as a cause. The discs play an important mechanical role in the spine, yet the relationship between disc function and back pain is poorly defined. The objective of this work was to develop a technique using magnetic resonance imaging (MRI) and three-dimensional modeling to measure in vivo disc deformations. Using this method, we found that disc geometry was measurable with precision less than the in-plane dimensions of a voxel (≈100 µm, 10% of the MRI pixel size)...

BACKGROUND: The unilateral biportal endoscopic (UBE) technique is a minimally invasive procedure for spinal surgery, while open microscopic discectomy is the most common surgical treatment for ruptured or herniated discs of the lumbar spine. A new endoscopic technique that uses a UBE approach has been applied to conventional arthroscopic systems for the treatment of spinal disease. In this study, we aimed to compare and evaluate the perioperative parameters and clinical outcomes, including recovery from surgery, pain and life quality modification, patient's satisfaction, and complications, between UBE and open lumbar microdiscectomy (OLM) for single-level discectomy procedures...

Cauda equina syndrome (CES) is a rare neurologic condition that is caused by compression of the cauda equina. Cauda equina consists of spinal nerves L2-L5, S1-S5 and the coccygeal nerve. The compression of these nerve roots can be caused mainly by lumbar disc herniation (45% of all causes). The diagnosis consists of two critical points: a) detailed history and physical examination and b) MRI or CT. The gold standard of the treatment of this syndrome is the surgical approach in combination with the timing of onset of symptoms...

PURPOSE: There are only two descriptions of posterior longitudinal ligament (PLL) at the lumbar spine level but its morphologic characteristics are different to cervical and thoracic levels. METHOD: Spine explantation (from Th12 to L5) followed by resection of the neural arch and the dural sheath in 13 fresh cadavers was performed. The PLL was isolated from other epidural structures and its width was measured and compared to the vertebral body width at each vertebral levels...
