Volume: 11 issue: 7, page(s): 1019-1024
Posterior spinal fusion (PSF) using all-pedicle screw constructs has become the standard procedure in the treatment of adolescent idiopathic scoliosis (AIS). However, there have been several reports that all-pedicle screw constructs or the use of pedicle screws at the upper instrumented vertebrae (UIV) increases the incidence of proximal junctional kyphosis (PJK). We aimed to evaluate the impact of instrumentation type on the incidence of PJK following PSF for AIS.

Long-Term Residual-Mobility and Adjacent Segment Disease After Total Lumbar Disc Replacement
Joep Kitzen, MD, Timon F. G. Vercoulen, MD, Martijn G. M. Schotanus, PhD, Sander M. J. van Kuijk, PhD, Nanne P. Kort, MD, PhD, Lodewijk W. van Rhijn, MD, PhD, Paul C. P. H. Willems, MD, PhD
doi : 10.1177/2192568220935813
Volume: 11 issue: 7, page(s): 1032-1039
Total disc replacement (TDR) has been introduced in order to preserve segmental motion and thus reduce adjacent segment disease (ASD) as seen after spinal fusion. However, it is uncertain whether these presumed beneficial effects remain. The aim of this study was to evaluate the long-term incidence of ASD and residual-mobility in relation to clinical outcome.

Volume: 11 issue: 7, page(s): 1040-1045
Surgical site infection (SSI) is one of the main complications of instrumented spinal fusion. The aim of our study was to evaluate infection recurrence (same bacteria) or reinfection (different bacteria) in posterior spinal fusion in children.

Update on the Biomechanics of the Craniocervical Junction, Part II: Alar Ligament
Basem Ishak, MD, Alexander von Glinski, MD, PhD, Graham Dupont, BS, Stefan Lachkar, BS, Emre Yilmaz, MD, Joe Iwanaga, PhD, Andreas Unterberg, MD, PhD, Rod Oskouian, MD, R. Shane Tubbs, PhD, Jens R. Chapman, MD
doi : 10.1177/2192568220941452
Volume: 11 issue: 7, page(s): 1064-1069
The strength of the alar ligament has been described inconsistently, possibly because of the nonphysiological biomechanical testing models, and the inability to test the ligament with both attachments simultaneously. The purpose of this biomechanical model was to reevaluate the alar ligament’s tensile strength with both bony attachments, while also keeping the transverse ligament intact, all in a more physiological biomechanical model that mimics the mechanism of traumatic injury closely.

Sunil Bhosale, MS (Ortho), Akil Prabhakar, MS (Ortho), Sudhir Srivastava, MS (Ortho), Aditya Raj, MS (Ortho), Shaligram Purohit, MS (Ortho), Nandan Marathe, MS (Ortho)
doi : 10.1177/2192568220941445
Volume: 11 issue: 7, page(s): 1070-1075
Spinal tuberculosis accounts for about 50% of cases among extra pulmonary osteoarticular tuberculosis. Resistance to drugs in spinal tuberculosis patients is on a rise and there is inadequate literature concentrating on the precise pattern of resistance in Indian subcontinent which harbors 24% of global prevalence. The aim was to study the pattern of drug resistance in spinal tuberculosis among first- and second-line drugs. Drug resistance is common in spinal tuberculosis and we intended to find the prevalence of various drug resistance patterns.
Implant Distribution Versus Implant Density in Lenke Type 1 Adolescent Idiopathic Scoliosis: Does the Position of the Screw Matter?
Brian L. Dial, MD, Valentine R. Esposito, MD, Anthony A. Catanzano, MD, Robert D. Fitch, MD, Robert K. Lark, MD
doi : 10.1177/2192568220941456
Volume: 11 issue: 7, page(s): 1076-1082
Previous studies have demonstrated that increased implant density (ID) results in improved coronal deformity correction. However, low-density constructs with strategically placed fixation points may achieve similar coronal correction. The purpose of this study was to identify key zones along the spinal fusion where high ID statistically correlated to improved coronal deformity correction. Our hypothesis was that high ID within the periapical zone would not be associated with increased percent Cobb correction.
Age Is Just a Number: Patient Age Does Not Affect Outcome Following Surgery for Osteoporotic Vertebral Compression Fractures

Volume: 11 issue: 7, page(s): 1083-1088
Multiple studies have shown that osteoporotic patients are at an increased risk for medical and surgical complications, making optimal management of these patients challenging. The purpose of this study was to determine the relationship between patient age and the likelihood of surgical complications, mortality, and 30-day readmission rates following surgery for osteoporotic vertebral compression fractures (OVCFs).

doi : 10.1177/2192568220959265
Volume: 11 issue: 7, page(s): 1121-1133
Outpatient cervical disc replacement (CDR) has been performed with an increasing trend in recent years. However, the safety profile surrounding outpatient CDR remains insufficient. The present study systematically reviewed the current studies about outpatient CDR and performed a meta-analysis to evaluate the current evidence on the safety of outpatient CDR as a comparison with the inpatient CDR.
Does Spondylolisthesis Affect Severity and Outcome of Degenerative Cervical Myelopathy? A Systematic Review and Meta-analysis
Renato Gondar, MD, Aria Nouri, MD, MSC, Gianpaolo Jannelli, MD, Karl Schaller, MD, Enrico Tessitore, MD
doi : 10.1177/2192568220960452
Volume: 11 issue: 7, page(s): 1134-1141
Degenerative cervical myelopathy (DCM) with spondylolisthesis remains not well defined, poorly studied, and underreported and plays a minor role in the therapeutic decision-making. Spondylolisthesis, however, is not uncommon and may result in dynamic injury to the spinal cord. We aim to describe the impact of spondylolisthesis in DCM severity and postoperative outcomes.

Venous Thromboembolism Prophylaxis in Elective Spine Surgery
Samantha Solaru, BS, Ram K. Alluri, MD, Jeffrey C. Wang, MD, Raymond J. Hah, MD
doi : 10.1177/2192568220962439
Volume: 11 issue: 7, page(s): 1148-1155
Venothromboembolic (VTE) complications, composed of deep vein thrombosis and pulmonary embolism are commonly observed in the perioperative setting. There are approximately 500?000 postoperative VTE cases annually in the United States and orthopedic procedures contribute significantly to this incidence. Data on the use of VTE prophylaxis in elective spinal surgery is sparse. This review aims to provide an updated consensus within the literature defining the risk factors, diagnosis, and the safety profile of routine use of pharmacological prophylaxis for VTE in elective spine surgery patients.
