Volume 38: Issue 6 (Jun 2023)
The optimal surgical approach for patients with multilevel degenerative cervical myelopathy (DCM) remains unknown. This systematic review and meta-analysis sought to compare anterior cervical discectomy and fusion (ACDF) versus posterior decompression (PD) in patients with DCM spanning ≥ 2 levels without ossification of the posterior longitudinal ligament.
Analysis of recovery trajectories in degenerative cervical myelopathy to facilitate improved patient counseling and individualized treatment recommendations
Blessing N. R. Jaja MD, PhD , Christopher D. Witiw MD, MS , Erin M. Harrington BMSc , Yingshi He MS , Ali Moghaddamjou MD , Michael G. Fehlings MD, PhD , and Jefferson R. Wilson MD, PhD
doi : 10.3171/2023.1.SPINE221053
There is a need to better understand and predict postsurgical outcomes for degenerative cervical myelopathy (DCM) patients, particularly to support treatment decisions for patients with mild DCM. The goal of this study was to identify and predict outcome trajectories for DCM patients up to 2 years postsurgery.

There is currently no consensus regarding the appropriate lower instrumented vertebra (LIV) for multilevel posterior cervical fusion (PCF) constructs between C7 and crossing the cervicothoracic junction (CTJ). The goal of the present study was to compare postoperative sagittal alignment and functional outcomes among adult patients presenting with cervical myelopathy undergoing multilevel PCF terminating at C7 versus spanning the CTJ.
Can semirigid fixation of the rostral instrumented segments prevent proximal junctional kyphosis in the case of long thoracolumbar fusions? A finite element study
Mate Turbucz MSc , Jennifer Fayad MSc , Agoston J. Pokorni MSc , Peter P. Varga MD , Peter E. Eltes MD, PhD , and Aron Lazary MD, PhD
doi : 10.3171/2023.1.SPINE22931
Proximal junctional kyphosis (PJK) is a relatively common complication following long instrumented posterior spinal fusion. Although several risk factors have been identified in the literature, previous biomechanical studies suggest that one of the leading causes is the sudden change in mobility between the instrumented and noninstrumented segments.
Additional growth of the spine and changes in spinal alignment after posterior spinal fusion in adolescent idiopathic scoliosis
Zhipeng Deng MD , Liang Wang MD , Yueming Song MD , Linnan Wang MD , Xi Yang MD , Limin Liu MD , and Lei Wang MD
doi : 10.3171/2023.2.SPINE221312
Previous studies have evaluated growth in spinal height immediately following surgical posterior correction of idiopathic scoliosis, yet have not reported on further spinal growth following surgery. The aims of this study were to investigate the characteristics of spinal growth after scoliosis surgery and determine whether they affect spinal alignment.

Luis M. Tumialán MD , Nolan Weinstein BS , S. Harrison Farber MD , Shashvat M. Desai MD , and Frederick F. Marciano MD, PhD
doi : 10.3171/2023.1.SPINE22882
The objective of this study was to identify factors that lead to a prolonged hospital stay or 30-day readmission after minimally invasive surgery (MIS) for transforaminal lumbar interbody fusion (TLIF) at a single institution.

Bertolotti syndrome is a clinical diagnosis given to patients with low-back pain arising from a lumbosacral transitional vertebra (LSTV). While biomechanical studies have demonstrated abnormal torques and range of motion occurring at and above this type of LSTV, the long-term effects of these biomechanical changes on the LSTV adjacent segments are not well understood. This study examined degenerative changes at segments superjacent to the LSTV in patients with Bertolotti syndrome.
Leveraging published randomized controlled trials to inform clinical trial design: a simulation-based study of laminectomy versus laminectomy and fusion

doi : 10.3171/2023.1.SPINE22957
The US-based Spinal Laminectomy versus Instrumented Pedicle Screw (SLIP) trial reported improvement in disability following laminectomy with fusion versus laminectomy alone for patients with lumbar spondylolisthesis. Despite using similar methods, a concurrent Swedish trial investigating the same question did not reach the same conclusion. The authors performed a simulation-based analysis to elucidate potential causes of these divergent results.
Vertebral bone quality score provides preoperative bone density assessment for patients undergoing lumbar spine surgery: a retrospective study
Mengyang Pu BS , Wentao Zhong MMed , Hongquan Heng BS , Jiahao Yu BS , Han Wu BS , Yifei Jin BS , Peng Zhang MD , and Yixin Shen MD
doi : 10.3171/2023.1.SPINE221187
The novel MRI-based vertebral bone quality (VBQ) score has been described as an opportunistic screening tool for osteoporosis, but the stability and practical value of this score deserve further investigation. The purpose of this study was to assess whether preoperative VBQ scores could assist in identifying reduced bone mineral density (BMD) or osteoporosis and evaluating the consistency between MRI systems with different field strengths.
