External validation of twelve existing survival prediction models for patients with spinal metastases.

Background Context: Survival prediction models for patients with spinal metastases may inform patients and clinicians in shared decision-making.

Purpose: To externally validate all existing survival prediction models for patients with spinal metastases.

Design: Prospective cohort study using retrospective data.

Radiotherapy and surgery: can this combination be further optimized for patients with metastatic spine disease?

This narrative review provides a comprehensive overview of the current status, recent advancements, and future directions in the management of metastatic spine disease using both radiotherapy and surgery. Emphasis has been put on the integrated use of radiotherapy and surgery, incorporating recent developments such as separation surgery, active dose sparing of the surgical field, and the implementation of carbon fiber-reinforced polymer implants. Future studies should explore the effects of minimizing the time between radiotherapy and surgery and investigate the potential of vertebral re-ossification after radiotherapy to obviate the need for stabilization surgery.

Laminectomy and fusion better maintains horizontal gaze than laminoplasty in cervical spondylotic myelopathy.

Background: Laminectomy and fusion (LF) and laminoplasty (LP) are common treatments for cervical spondylotic myelopathy and myeloradiculopathy. While both procedures show similar clinical improvement, LF requires bony fusion while LP offers motion preservation. Cervical sagittal alignment and horizontal gaze maintenance are key outcome measures, but their comparative effects between LF and LP remain unclear.

Comparative Analysis of Surgical Outcomes in Separation Surgery vs. Anterior Reconstruction for Metastatic Epidural Spinal Cord Compression.

Study Design: Retrospectively matched case-control study.

Objective: To compare intraoperative and postoperative outcomes between separation surgery and corpectomy with anterior reconstruction for patients with metastatic epidural spinal cord compression (MESCC).

Summary Of Background Data: The primary goal of surgery for MESCC is to preserve and improve neurological function.

Glycemic laboratory values are associated with increased length of stay and 90-day revision risk following surgical management of adult spinal deformity.

Background Context: Diabetes mellitus (DM) is a common comorbidity among patients undergoing spinal fusion for adult spinal deformity (ASD) surgery. An elevated Hemoglobin A1c (HbA1c) and elevated postoperative glucose have been shown to increase the risk of complications following spine and other orthopedic surgeries; however, data is limited for ASD.

Purpose: To investigate glycemic control and ASD surgery to inform surgical decision making, medical optimization, and patient education.
