Comparison of Posterior Unilateral Vertebral Column Resection Versus Posterior Vertebral Column Resection for Severe Thoracolumbar Angular Kyphosis as a Revision Surgical Modality: A Retrospective Cohort Study
This study included 58 patients who were divided into the PUVCR group and the posterior vertebral column resection (PVCR) group. Age (P=0.810), sex distribution (P=0.500), and vertebrae that underwent surgery (P=0.638) were similar in the 2 groups. Shorter mean operation time was observed in the PUVCR group as compared with the PVCR group (P (Source: Journal of Spinal Disorders and Techniques)

Fear-avoidance and Patients’ Reported Outcomes are Strongly Correlated With Biomechanical Gait Parameters in Cervical Spondylotic Myelopathy Patients
Study Design: This was a prospective cohort study. Objective: The aim was to explores whether fear-avoidance is associated with altered gait patterns in cervical spinal myelopathy (CSM) patients. Summary of Background Data: Fear-avoidance is associated with activity restriction and emotional distress in chronic pain patients and with poorer spine surgery outcomes. In adults with spinal deformity, fear and avoidance correlates with gait pattern disruptions. Patients having CSM also display distorted gait. Methods: Ninety CSM patients completed the Tampa Scale for Kinesiophobia (TSK) questionnaire, a...

A 15-Year Follow-up Retrospective Study on 959 Spine Surgeries: What Can We Learn From Real-world Data?
Study Design: This was a retrospective study. Objective: The aim of this study was to investigate the patient flow and need for additional surgery after first-time lower back surgery. Next, we analyzed the patients who developed chronic low back pain (LBP) and were treated with spinal cord stimulation. Summary of Background Data: LBP has a lifetime prevalence of 84% and imposes a high economic burden. Treatment is focused on preventing chronic pain. Research has shown the efficacy of treatment options. However, less is known about who benefits the most from which therapy and when they should be positioned...

Fractional Curve in Adult Spinal Deformity: Is it a Driver of or a Compensation for Coronal Malalignment?
The objective of this study was to investigate the role of the fractional curve (FC) on global coronal malalignment. Summary of Background Data: Despite being very common, the role of the coronal FC as either a driver or compensation for global coronal malalignment is not well documented Materials and Methods: Patients with the following characteristics were extracted from a prospective multicenter database: lumbar/thoracolumbar (TL) major coronal curve>15 degrees, apex at T11–L3, lower end vertebra at L3 or L4, above 45 years old, and FC>5 degrees. In addition to the classic radiographic parameters, baseli...

Fear Avoidance Beliefs and Outcome After Surgery for Degenerative Lumbar Spine
Conclusions: In our study, the FABQ was not associated with functional outcome following surgery for degenerative lumbar spine. Other psychological patient-reported measures are needed to refine selection of patients undergoing spine surgery in order to ensure better outcomes.

The Relationship Between Cervical Sagittal Balance and Adjacent Segment Disease After Three-level Anterior Cervical Discectomy and Fusion
Conclusions: Unlike studies on 1-level and 2-level ACDF, this study found that cervical spinal alignment was not associated with ASD development after 3-level ACDF. ASD development also had no impact on clinical outcomes at 2 years. Level of Evidence: Level III—nonrandomized cohort study. (Source: Journal of Spinal Disorders and Techniques)

A Retrospective Analysis of Superior Facet Joint Violation Between Open and Minimally Invasive Transforaminal Lumbar Interbody Fusion and its Relation to Adjacent Segment Disease
Study Design: A retrospective study. Objective: The aim was to analyze the superior facet joint violation (SFV) between open transforaminal lumbar interbody fusion (open-TLIF) and minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) and its effect on the superior and inferior adjacent segment disc height, segmental lordosis, lumbar lordosis, and facet joint degeneration. Summary of Background Data: We compared SFV between open-TLIF and MIS-TLIF and its correlation with different factors as well as its effect on adjacent segment disease. Materials and Methods: We retrospectively stud...

One-Year Outcomes of Chiari Type 1 Malformation and Syringomyelia Treated With Posterior Fossa Decompression
The objective of this study was to evaluate posterior fossa structural differences between Chiari type 1 malformation with and without syringomyelia, and assess data of the improvement of syringomyelia after different surgical options. Summary of Background Data: Syringomyelia is among the most common concomitant complications of Chiari malformation (CM). However, posterior fossa decompression cannot definitely make the syringomyelia disappear even in the long term. Also, there are no universal criteria defining improvement in syrinx. Materials and Methods: All admitted CM patients at our institution from 201...

Lumbar Fusion for Spondylolisthesis: A Bayesian Network Meta-analysis of Randomized Controlled Trials
Conclusions: OTLIF for spondylolisthesis was found to be the more efficient procedure in terms of radiographic fusion and ODI scores. Importantly, MTLIF is most likely to have a lower associated complication rate compared with other fusion procedures. (Source: Journal of Spinal Disorders and Techniques)

Comparison of Zero-profile Anchored Spacer Versus Plate-and-Cage After 1-Level ACDF With Complete Uncinate Process Resection: A 3-Year Assessment of Radiographic and Clinical Outcomes
Study Design: This is a retrospective study. Objective: The purpose of this study is to compare the zero-profile anchored spacer device (Zero-p) and traditional plate-and-cage implant (plate-and-cage) in anterior cervical discectomy and fusion (ACDF) with complete uncinate process resection (UPR) to treat 1-level cervical degenerative disk disease. Summary of Background Data: We retrospectively surveyed the data from all patients who underwent single-level ACDF with complete UPR between 2009 and 2013. Patients and Methods: In total, 80 patients participated in 3 years of follow-up. Among them, Zero...

Conclusions: Surgery-induced weight loss before an ACDF in obese patients is associated with reduced 90-day complication and readmission rates. Orthopaedic and bariatric surgeons should counsel obese patients on the benefits of BS following ACDFs. (Source: Journal of Spinal Disorders and Techniques)

Regional Anesthesia for Spine Surgery
Recent advancements in spine surgery anesthesia techniques and pain management has led to a paradigm shift from conventional open spinal procedures to minimally invasive spine surgeries performed on an outpatient basis. Spinal anesthesia and epidural anesthesia alone or in combination with spinal are common regional anesthesia modalities used in spine surgeries. New modalities of regional analgesia have emerged recently including erector spinae and thoracolumbar interfascial plane block, aimed at decreasing perioperative pain and enhancing early recovery in patients undergoing spine surgery. In this narrative review we dis...
