Local Mechanical Environment and Spinal Trabecular Volumetric Bone Mineral Density Measured by Quantitative Computed Tomography: A Study on Lumbar Lordosis.

Objective: There have been some reports on the association between spinal balance parameters and regional bone mineral density (BMD), but the results are controversial. The purpose of this study is to evaluate the relationship between spinopelvic parameters and regional volumetric BMDs (vBMDs) measured by quantitative computed tomography (QCT) in the lumbosacral region of patients undergoing lumbar fusion surgery.

Methods: The data of consecutive patients undergoing posterior lumbar spinal fusion with preoperative computed tomography was reviewed.

Lumbar disc herniation: what has the Spine Patient Outcomes Research Trial taught us?

Introduction: Intervertebral disc herniation (IDH) can cause back pain and/or radiculopathy and accounts for a significant portion of patients having spinal surgery in the USA. One of the most impactful and well-executed randomized trials to study diagnosis, treatments, and outcomes in patients with three commonly treated spinal conditions was the Spine Patient Outcomes Research Trial (SPORT). This study and the subsequent data analyses have resulted in numerous publications related to IDH.

Restoration of lumbar lordosis after minimally invasive transforaminal lumbar interbody fusion: a systematic review.

Background: Transforaminal lumbar interbody fusion (TLIF) is a well-accepted surgical technique for the treatment of degenerative spinal conditions and spinal deformity. The TLIF procedure can be performed open or using minimally invasive techniques. While several studies have found that minimally invasive TLIF (MI-TLIF) has advantages over open TLIF procedures with less blood loss, postoperative pain and hospital length of stay, opponents of the minimally invasive technique cite the lack of restoration of lumbar lordosis as a major drawback.

Urinary N-Telopeptide Can Predict Pseudarthrosis After Anterior Cervical Decompression and Fusion: A Prospective Study.

Study Design: Prospective cohort study.

Objective: To examine preoperative urinary cross-linked n-telopeptide (uNTx) and assess for association with fusion rates in patients undergoing single and multi-level anterior cervical decompression and fusion (ACDF).

Summary Of Background Data: Although high rates of fusion have been reported for ACDF, the risk of pseudarthrosis remains substantial.

Regional bone mineral density differences measured by quantitative computed tomography: does the standard clinically used L1-L2 average correlate with the entire lumbosacral spine?

Background Context: Quantitative computed tomography (QCT) of the lumbar spine is used as an alternative to dual-energy X-ray absorptiometry in assessing bone mineral density (BMD). The average BMD of L1-L2 is the standard reportable metric used for diagnostic purposes according to current recommendations. The density of L1 and L2 has also been proposed as a reference value for the remaining lumbosacral vertebrae and is commonly used as a surrogate marker for overall bone health.
