Article Synopsis
- Double-crush syndrome (DCS) involves both peripheral nerve compression and spinal nerve root impingement, and this study aimed to compare electrodiagnostic results in patients undergoing carpal tunnel release (CTR) versus those also receiving cervical diskectomy and fusion for DCS.
- The study analyzed data from 54 DCS patients and 137 CTR-only patients, noting that DCS patients had shorter sensory latencies, slower wrist motor velocity, and positive EMG findings in muscles like the biceps and triceps.
- The findings suggest that DCS patients exhibit distinct electrodiagnostic patterns compared to CTR-only patients, emphasizing the need for healthcare providers to consider cervical issues when encountering related EMG abnormalities.
Study Design: Retrospective Cohort Study.
Objective: To explore the differences in Medicare reimbursement for lumbar fusion performed at an orthopaedic specialty hospital (OSH) and a tertiary referral center and to elucidate drivers of Medicare reimbursement differences.
Summary Of Background Data: To provide more cost-efficient care, appropriately selected patients are increasingly being transitioned to OSHs for lumbar fusion procedures.
Study Design: Retrospective Cohort.
Objective: To determine if outcomes varied between patients based on physical therapy (PT) attendance after lumbar fusion surgery.
Summary Of Background Data: The literature has been mixed regarding the efficacy of postoperative PT to improve disability and back pain, as measured by patient-reported outcome measures.
Case: Although implanted tuberculosis (TB) is rare, a single lot of cellular bone matrix was found to be infected with TB, leading to devastating outcomes. We present 2 cases referred to our institution because of instrumentation failure caused by TB inoculation of cellular bone matrix.
Conclusion: Irrespective of spinal region of implanted TB infection, excision of infected bone, extensive irrigation and debridement, and instrumented stabilization are of primary importance to ensure TB eradication and adequate stabilization.
Objectives: To evaluate the injury, patient, and microbiological characteristics that place patients at risk for recalcitrant fracture-related infection and osteomyelitis despite appropriate initial treatment.
Design: Retrospective chart review.
Setting: Three level I trauma centers.
Study Design: Prospective cohort study.
Objective: Our primary study was to investigate whether the degree of postoperative facet and disk space distraction following anterior cervical discectomy and fusion (ACDF) affects the rate of postoperative dysphagia.
Summary Of Background Data: Although ACDF is safe and well tolerated, postoperative dysphagia remains a common complication.
Purpose: Epidural corticosteroid injections (ESI) are a mainstay of nonoperative treatment for patients with lumbar spine pathology. Recent literature evaluating infection risk following ESI after elective orthopedic surgery has produced conflicting evidence. Our primary objective was to review the literature and provide a larger meta-analysis analyzing the temporal effects of steroid injections on the risk of infection following lumbar spine surgery.

- The study examined how medical comorbidities and surgical factors impact healthcare costs for Medicare patients undergoing lumbar fusion surgery.
- Data was gathered from a previous reimbursement database, including 500 patients, focusing on total costs, complications, and readmissions.
- Key findings indicate that certain surgical types (like ALIF) and medical issues (like congestive heart failure) significantly increase costs and risks for complications, with specific predictors identified for surgical complications and readmissions.
Context: Studies on adult spinal deformity have shown spinopelvic malalignment results in worse outcomes. However, it is unclear if this relationship exists in patients with single-level degenerative spondylolisthesis (DS) receiving short-segment fusions.
Aims: To determine if spinopelvic alignment affects patient-reported outcome measures (PROMs) after posterior lumbar decompression and fusion (PLDF) with or without a transforaminal lumbar interbody fusion in patients with L4-5 DS.
Introduction: Determination of what constitutes necessary surgery in the setting of acute hospital resource strain during the COVID-19 pandemic is an unprecedented challenge for healthcare systems. Over the past two years during the COVID-19 pandemic, there have been many changes in reviews of medically necessary spine surgery. There continues to be no clear guidelines on recommendations and further discussion is necessary to continue to provide appropriate and high-level care during future pandemics.
View Article and Find Full Text PDFDiscogenic low back pain is a common musculoskeletal complaint in patients presenting to orthopaedic surgeons. In addition to surgical options, there are several nonsurgical intradiscal treatments that have gained interest, ranging from biologic, nonbiologic, cell-based, and molecular therapies. However, there is limited evidence for many of these techniques, and some are still in the clinical trial stage.
View Article and Find Full Text PDFObjective: For patients with cervical and thoracolumbar AO Spine type C injuries, the authors sought to 1) identify whether preoperative vertebral column translation is predictive of a complete spinal cord injury (SCI) and 2) identify whether preoperative or postoperative vertebral column translation is predictive of neurological improvement after surgical decompression.
Methods: All patients who underwent operative treatment for cervical and thoracolumbar AO Spine type C injuries at the authors' institution between 2006 and 2021 were identified. CT and MRI were utilized to measure vertebral column translation in millimeters prior to and after surgery.
Objective: The purpose of this retrospective cohort study was to evaluate the effect of tranexamic acid (TXA) on reducing perioperative blood loss and length of stay after transforaminal lumbar interbody fusion (TLIF). Spine surgery is associated with the potential for significant blood loss, and adequate hemostasis is essential to visualizing crucial structures during the approach and procedure. Although TXA use has been extensively studied in the pediatric and adult spinal deformity literature, there is a dearth of literature on its efficacy in reducing blood loss for patients who undergo 1- to 3-level TLIF.

Purpose/hypothesis: The purpose of this study was to evaluate the effect of the 2020 COVID-19 period on emergency department (ED) visits for sports-related injuries in the United States. It was hypothesized that such visits decreased in response to the pandemic conditions.
Background: The popularity of both indoor and outdoor rock climbing has dramatically increased over the last decade. The purpose of this study is to evaluate trends in USA climbing injury rates as well as assess specific injury characteristics, especially in the context of indoor and outdoor climbing.
Methods: The National Electronic Injury Surveillance System database was queried (2010-2019) to compare national weighted injury estimates and compare various injury characteristics from climbers presenting to USA emergency departments.
