Patients With Poor Baseline Mental Health May Experience Significant Improvements in Pain and Disability After Minimally Invasive Transforaminal Lumbar Interbody Fusion: A 5-Year Follow-up Study.

STUDY DESIGN: A retrospective study using prospectively collected registry data. OBJECTIVE: Examine the influence of preoperative mental health on outcomes after Minimally Invasive Transforaminal Lumbar Interbody Fusion (MIS-TLIF).

The effect of MIS-TLIF on mental health also remains unclear. METHODS: Prospectively collected registry data of 226 patients who underwent single-leve

Evaluating low back pain in adolescents.

Low back pain in adolescents is a common complaint in primary care. With an average prevalence rate of 40%, adolescent low back pain correlates with greater healthcare use, higher incidences of adult back pain, and negative effects on overall well-being. A thorough history and physical examination can increase early detection and accurate diagnosis while ensuring the judicious use of diagnostic modalities. Although underlying serious pathology is rare in adolescents with low back pain, clinicians should recognize specific signs and symptoms that necessitate urgent evaluation and intervention.

Percutaneous Endoscopic Laminotomy with Flavectomy by Uniportal, Unilateral Approach for the Lumbar Canal or Lateral Recess Stenosis.

OBJECTIVE: To evaluate clinical feasibility and safety of percutaneous endoscopic decompression by a uniportal, unilateral approach for lumbar canal or lateral recess stenosis.

Two-year outcome of hydroxyapatite mixed with autogenous bone marrow and local bone graft for posterolateral lumbar fusion.

OBJECTIVE: To determine the outcome of hydroxyapatite (HA) mixed with autogenous bone marrow (BM) and local bone graft in posterolateral lumbar fusion. MATERIAL AND METHOD: Twenty-three patients who had posterolateral fusion with posterior instrument using HA mixed with BM and local bone graft between December 2003 and August 2005 were prospective analyzed. Degree of pain using visual analog scale (VAS) was evaluated at preoperative and 2, 4, 6, 9, 12, and 24 postoperative months. Radiographs were assessed for spinal fusion at 4, 6, 9, 12, and 24 postoperative months. RESULTS: The improvemen

Contribution of recombinant human bone morphogenetic protein-2 to the rapid creation of interbody fusion when used in transforaminal lumbar interbody fusion: a preliminary report. Invited submission from the Joint Section Meeting on Disorders of the Spine and Peripheral Nerves, March 2004.

OBJECT: The authors compared fusion rates in transforaminal lumbar interbody fusion (TLIFs) when using either autograft or bone morphogenetic protein (BMP) placed in the interbody space. METHODS: Between September 2002 and December 2003, the authors performed 44 TLIF operations. Follow-up data were available for 40 patients. Of the 40 procedures, 19 involved cages filled with iliac crest autograft (Group 1) and 21 involved cages filled with a medium kit of recombinant human (rh) BMP-2 (Group 2). In all Group 2 patients, one BMP sponge was placed anterior to the cage and another was placed wit

Minimally Invasive Oblique Lateral Lumbar Interbody Fusion Combined with Anterolateral Screw Fixation for Lumbar Degenerative Disc Disease.

OBJECTIVE: The purposes of the present study were to introduce an indirect decompression using oblique lateral lumbar interbody fusion combined with anterolateral screw fixation (OLIF-AF) for the treatment of lumbar degenerative disc disease and examine the clinical efficacy and radiographic outcomes. METHODS: A total of 65 patients had undergone single-level OLIF-AF at L2-L5 from December 2017 to August 2018. The cross-sectional area of the thecal sac was evaluated using magnetic resonance imaging. The disk height, foraminal height (FH), and degree of upper vertebral slippage were evaluated

The accuracy of 3D image navigation with a cutaneously fixed dynamic reference frame in minimally invasive transforaminal lumbar interbody fusion.

OBJECTIVE: In contrast to preoperative image-based 3D navigation systems, which require surgeon-dependent registration, an intraoperative cone-beam computed tomography (cb-CT) image-based 3D navigation system allows automatic registration during the acquisition of 3D images intraoperatively. Thus, the need for spinal exposure for point matching is obviated, making a cb-CT image-based navigation system ideal for use in minimally invasive spinal procedures. Conventionally, the dynamic reference frame (DRF) is mounted to an adjacent spinous process or iliac bone through a separate incision. Howev

Gorham disease of the cervical spine-a case report and review of the literature.

STUDY DESIGN: A case report and literature review of Gorham disease involving the cervical spine. OBJECTIVES: To describe the clinical course and surgical management of Gorham disease of the cervical spine. The pathologic features and various treatment methods are also discussed. SUMMARY OF BACKGROUND DATA: Gorham disease is a rare idiopathic disease that possesses distinctive clinical, pathologic, and radiologic features.

There have been no prior reports of this condition following lumbar spine surgery carried out under hypotensive anesthetic. METHODS: Notes review, clinical examination, plain radiographs, and magnetic resonance imaging diagnosed three patients who developed avascular necrosis of the femoral head

Degenerative Pathways of Lumbar Motion Segments--A Comparison in Two Samples of Patients with Persistent Low Back Pain.

BACKGROUND: Magnetic resonance imaging (MRI) is used to identify spinal pathoanatomy in people with persistent low back pain. However, the clinical relevance of spinal degenerative MRI findings remains uncertain. Although multiple MRI findings are almost always present at the same time, research into the association with clinical outcomes (such as pain) has predominantly focused on individual MRI findings. This study aimed to: (i) investigate how multiple MRI lumbar spine findings cluster together within two different samples of patients with low back pain, (ii) classify these clusters into hy
