Spondylolisthesis in Young Patients in a Large National Cohort: Reoperation Rate Depends on Surgical Approach.

Background: The current literature investigating surgical treatments for lumbar spondylolisthesis in adolescent patients is limited by small sample sizes. There are high reoperation rates, and posterior interbody fusion has not been reported to help. The current study aimed to utilize a nationwide database to investigate outcomes of spinal fusion for spondylolisthesis in young patients.

New Technique for Treatment of Spondylolysis and Contralateral Facet Fracture Using Navigation and Robotics: A Case Report.

Case: A healthy 15-year-old male competitive hockey player presented with acute-on-chronic lower back pain was found to have a bilateral pars defect. After conservative treatment, subsequent computed tomography imaging demonstrated partial healing of the right-sided facet fracture but persistent left-sided pars fracture. A novel technique was performed, using robotic navigation to assist in laminar screw placement and to determine the optimal trajectory for subsequent microscopic surgery and bone grafting.

Comparison of rostral facet joint violations in robotic- and navigation-assisted pedicle screw placement for adult lumbar spine instrumentation.

Background Context: Facet joint violation by pedicle screws may lead to adjacent-segment disease and postoperative pain. Previous studies have reported the incidence of rostral facet joint violation using various pedicle screw insertion techniques. However, the incidence of facet joint violations with robotic guidance has not been determined.

Lumbar Total Disc Replacement Leads to Increased Subsequent Facet Injections Compared to Anterolateral Lumbar Interbody Fusions.

Study Design: Retrospective Matched Cohort.

Objective: Despite known consequences to the facet joints following lumbar total disc replacement (TDR), there is limited data on facet injection usage for persistent postoperative pain. This study uses real-world data to compare the usage of therapeutic lumbar facet injections as a measure of symptomatic facet arthrosis following single-level, stand-alone TDR vs anterolateral lumbar interbody fusion (ALIF/LLIF).

Incidental dural tears during pediatric posterior spinal fusions.

Purpose: To characterize the frequency of incidental dural tears in pediatric spine surgery, their treatment, complications, and results of long-term follow-up.

Methods: A retrospective review of all pediatric patients who underwent a posterior spinal fusion (PSF) between 2004-2019 at a tertiary children's hospital was conducted. Electronic medical records were reviewed for patient demographics, intra-operative data, presence of an incidental dural tear, repair method, and patient outcomes.

Geographic Access to Pediatric Orthopedic Surgeons in the United States: An Analysis of Sociodemographic Factors.

Background: It is unclear how pediatric orthopedic surgeons are geographically distributed relative to their patients. The purpose of this study was to evaluate the geographic distribution of pediatric orthopedic surgeons in the United States.

Materials And Methods: County-level data of actively practicing pediatric orthopedic surgeons were identified by matching several registries and membership logs.

Risk Factors for Reoperation Following Single-Level Cervical Disc Arthroplasty as Utilized in a Representative Sample of United States Clinical Practice: A Retrospective PearlDiver Study.

Study Design: Retrospective Cohort.

Objectives: Most data regarding cervical disc arthroplasty (CDA) outcomes are from highly controlled clinical trials with strict inclusion/exclusion criteria. This study aimed to identify risk factors for CDA reoperation, in "real world" clinical practice using a national insurance claims database.

Vertebral Artery Dissection in the Setting of Unstable Os Odontoideum: A Case Report.

Case: A healthy 5-year-old boy presented with a gradual onset of headaches and acute global right-sided weakness over 10 days. The work-up revealed unstable os odontoideum leading to multiple posterior circulation infarcts with vertebral artery dissection. He underwent antiplatelet therapy, cervical collar immobilization, and delayed occiput to C2 posterior spinal fusion and instrumentation with iliac crest autograft.

Single-Level Anterolateral and Posterior Interbody Fusion Techniques are Associated With Equivalent Long-Term Lumbar Reoperations.

Study Design: Retrospective cohort study.

Objective: This study compares reoperation rates and complications following single-level anterior lumbar interbody fusion (ALIF)/lateral lumbar interbody fusion (LLIF) and transforaminal lumbar interbody fusion (TLIF)/posterior lumbar interbody fusion (PLIF).

Summary Of Background Data: ALIF, LLIF, TLIF, and PLIF are widely used for degenerative disc disease.

New technique and case report: Robot-assisted intralaminar screw fixation of spondylolysis in an adolescent.

Introduction: Management of spondylolysis in adolescents is generally successful with conservative management. Uncommonly, surgical fixation is necessary for refractory cases. Direct repair with intralaminar screws is one commonly utilized technique.

Medical Encounters and Treatment Outcomes in Ironman-Distance Triathlon.

Purpose: This study aimed to examine the injury and illness characteristics, treatments, and outcomes at elite ultraendurance triathlon events.

Methods: We quantified participant demographics, injury types, treatments, and disposition for medical encounters at 27 Ironman-distance triathlon championships from 1989 to 2019. We then calculated the likelihood of concurrent medical complaints in each encounter.
