Efficacy of Preoperative Autologous Blood Donation for Surgical Treatment of Thoracic Spinal Stenosis: A Propensity-Matched Cohort Study.

Objective: Thoracic spinal stenosis (TSS) surgeries necessitate a substantial amount of allogeneic blood resources. However, the efficacy of preoperative autologous blood donation (PABD) in TSS surgery has not been clearly evaluated. Therefore, we aimed to evaluate the efficacy of PABD for TSS surgery.

Incidence, clinical features, and risk factors for acute pancreatitis following posterior instrumented fusion surgery for lumbar degenerative disease: a single-center, retrospective analysis of 20,929 patients.

Purpose: The aim of this study is to identify the incidence, clinical features, and risk factors for postoperative acute pancreatitis (PAP) after lumbar surgery.

Methods: We retrospectively analyzed patients who developed PAP after posterior lumbar fusion surgery. For each PAP patient, data were collected for four controls who underwent procedures in the same period and did not develop PAP.

Learning Curve and Clinical Outcomes of Ultrasonic Osteotome-based En Bloc Laminectomy for Thoracic Ossification of the Ligamentum Flavum.

Objective: Despite rapid advances in minimally invasive surgery, en bloc laminectomy remains the most common surgical approach for treating thoracic ossification of the ligamentum flavum (TOLF). However, the learning curve of this risky operation is rarely reported. Therefore, we aimed to describe and analyze the learning curve of ultrasonic osteotome-based en bloc laminectomy for TOLF.

Development and validation of a novel thoracic spinal stenosis surgical invasiveness index: a single-center study based on 989 patients.

Background Context: Surgical invasiveness indices have been established for general spine surgery (surgical invasiveness index [SII]), spine deformity, and metastatic spine tumors; however, a specific index for thoracic spinal stenosis (TSS) has not been developed.

Purpose: To develop and validate a novel invasiveness index, incorporating TSS-specific factors for open posterior TSS surgery, which may facilitate the prediction of operative duration and intraoperative blood loss, and the stratification of surgical risk.

Study Design: A retrospective observational study.

Incidence, Risk Factors, and Outcomes of Symptomatic Bone Cement Displacement following Percutaneous Kyphoplasty for Osteoporotic Vertebral Compression Fracture: A Single Center Study.

Study Design: Retrospective.

Background: Symptomatic bone cement displacement (BCD) is a rare complication following percutaneous kyphoplasty (PKP) interventions for osteoporotic vertebral compression fracture (OVCF). This study aimed to investigate the incidence and the outcomes of symptomatic BCD comprehensively and identify its risk factors.

Thirty-day Unplanned Reoperations After Posterior Surgery for Thoracic Spinal Stenosis: A Single-center Study Based on 1948 Patients.

Study Design: A retrospective study.

Objective: The purpose of this study is to identify the incidences, causes, and risk factors of 30-day unplanned reoperation of posterior surgery for thoracic spinal stenosis (TSS) based on 1948 patients in a single center.

Summary Of Background Data: Unplanned reoperation is suggested to be a useful quality indicator for spine surgery.
