STUDY DESIGN: Randomized controlled trial (RCT). OBJECTIVE: Compare the efficacy of a multimodal, opioid-free (OF) pain management pathway with a traditional opioid-containing (OC) pathway in patients undergoing anterior cervical procedures. SUMMARY OF BACKGROUND DATA: Previous studies have compared opioid-based pain regimens to opioid-sparing regimens following cervical spine surgery, but have been limited by high rates of crossover, retrospective designs, reliance on indwelling pain catheters, opioid utilization for early postoperative analgesia, and/or a lack of patient-reported outcome measures...

STUDY DESIGN: Systematic review and meta-analysis of literature. OBJECTIVE: The aim of the presented study is to assess whether the reduction of high-grade spondylolisthesis (HGS) through the correction of lumbosacral kyphosis leads to a decrease in the sagittal spinopelvic compensatory mechanisms. SUMMARY OF BACKGROUND DATA: HGS is as an anterior translation of a vertebra, >50%. It is also characterized by a kyphotic deformity of the affected level...

STUDY DESIGN: Epidemiological study. OBJECTIVE: This study aimed to evaluate the annual incidence of spondylolisthesis requiring surgery in Italy and the epidemiological characteristics of the patients. BACKGROUND: The health care system continues to incur considerable costs as a result of low-back pain. Segmental instability of the lumbar spine has attracted significant interest from researchers as a potential mechanism leading to mechanical low back pain...

STUDY DESIGN: Retrospective review. OBJECTIVES: We substratified the mFI-5 frailty index to reflect controlled and uncontrolled conditions and assess their relationship to perioperative complications. SUMMARY OF BACKGROUND DATA: Risk assessment before adult spinal deformity (ASD) surgery is critical because the surgery is highly invasive with a high complication rate. Although frailty is associated with risk of surgical complications, current frailty measures do not differentiate between controlled and uncontrolled conditions...

STUDY DESIGN: Prospective cross-sectional survey. OBJECTIVE: To identify timelines for when athletes may be considered safe to return to varying athletic activities after sustaining cervical spine fractures. BACKGROUND: While acute management and detection of cervical spine fractures have been areas of comprehensive investigation, insight into timelines for when athletes may return to different athletic activities after sustaining such fractures is limited...

For the first time on a large scale, patients can ask targeted questions and receive similarly targeted answers...

STUDY DESIGN: A retrospective study. OBJECTIVE: In this study, a cervical degenerative quantitative scoring system was used to identify the risk factors for disc height loss after cervical disc replacement (CDR) and to verify their accuracy. BACKGROUND: Disc height loss after CDR is drawing much attention. Preoperative cervical degeneration has been proven related to postoperative disc height loss but lacked quantitative verification. PATIENTS AND METHODS: A total of 160 patients who underwent CDR with the Prestige-LP disc at our hospital between January 2011 and December 2016 were retrospectively reviewed...

STUDY DESIGN: Retrospective review. OBJECTIVE: To determine whether the Activity Measure for Post-Acute Care (AM-PAC) "6-Clicks" score is associated with the development of postoperative ileus. SUMMARY OF BACKGROUND DATA: Adult spinal deformity (ASD) surgery has a high complication rate. One common complication is postoperative ileus, and poor postoperative mobility has been implicated as a modifiable risk factor for this condition. METHODS: Eighty-five ASD surgeries in which ≥5 levels were fused were identified in a single institution database...

STUDY DESIGN: Retrospective cohort study. OBJECTION: To report our modified tap-drilling technique for mid-cervical pedicle screw placement and to evaluate its safety and accuracy. SUMMARY OF BACKGROUND DATA: Cervical pedicle screw fixation, which provides a strong stabilization, has been a major concern due to the potential risks to neurovascular structures despite its increasing use. Several insertion techniques have been described so far to improve the cervical pedicle screw placement accuracy...

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: The purpose of this study is to investigate whether weekday lumbar spine fusion surgery has an impact on surgical and inpatient physical therapy (PT) outcomes. SUMMARY OF BACKGROUND DATA: Timing of surgery has been implicated as a factor that may impact outcomes after spine surgery. Previous literature suggests that there may be an adverse effect to having surgery on the weekend. METHODS: All patients ≥18 years who underwent primary lumbar spinal fusion from 2014 to 2020 were retrospectively identified...

STUDY DESIGN: Retrospective study. OBJECTIVE: (1) To compare cervical magnetic resonance imaging (MRI) radiology reports to a validated grading system for cervical foraminal stenosis (FS) and (2) to evaluate whether the severity of cervical neural FS on MRI correlates to motor weakness or patient-reported outcomes. BACKGROUND: Radiology reports of cervical spine MRI are often reviewed to assess the degree of neural FS. However, research looking at the association between these reports and objective MRI findings, as well as clinical symptoms, is lacking...

STUDY DESIGN: Retrospective cohort study. OBJECTIVES: The study aimed to (1) compare baseline demographics of patients undergoing surgery for SEA who were/were not readmitted; (2) identify risk factors for 90-day readmissions; and (3) quantify 90-day episode-of-care health care costs. BACKGROUND: Spinal epidural abscess (SEA), while rare, occurring ~2.5-5.1/10,000 admissions, may lead to permanent neurologic deficits and mortality. Definitive treatment often involves surgical intervention via decompression...

STUDY DESIGN: Case control. OBJECTIVE: Traumatic cervical spine injuries are associated with a substantial risk of mortality. The aim of this study is to develop a novel mortality prediction model for patients with cervical trauma who require operative treatment. SUMMARY OF BACKGROUND DATA: Patients with cervical spine trauma have a high risk of postoperative complications and mortality. There are few reliable systems that can accurately predict mortality after surgery for cervical spine trauma, and those that do exist are typically not specific to cervical trauma...

STUDY DESIGN: A prospective, randomized, placebo-controlled, double-blinded study. OBJECTIVE: To examine the effect of intraoperative epidural administration of Depo-Medrol on postoperative back pain and radiculitis symptoms in patients undergoing Transforaminal Lumbar Interbody Fusion (TLIF). SUMMARY OF BACKGROUND DATA: Postoperative pain is commonly experienced by patients undergoing spinal fusion surgery. Adequate management of intense pain is necessary to encourage early ambulation, increase patient satisfaction, and limit opioid consumption...
