International and Multicenter Prospective Controlled Study of Dysphagia After Anterior Cervical Spine Surgery.

Background: In the context of anterior approach to the cervical spine, dysphagia is a common complication and still without a clear distinction of risk factors.

Objective: To analyze the risk factors of dysphagia after cervical spine surgery.

Methods: Multicenter prospective study evaluated patients who underwent anterior cervical spine surgery for degenerative pathologies, studying surgical, anesthesia, base disease, and radiological variables (preoperatively, 24 hours, 1 and 3 weeks, and 6 months after surgery), with control group matched.

Clinical evaluation of a new kyphoplasty technique with directed cement flow.

Study Design: Prospective, single-center 2-year study.

Objective: The long-term clinical performance of a new cement-directing kyphoplasty system was evaluated for treatment of painful osteoporotic compression fractures.

Summary Of Background Data: Cement leakage is a common clinical complication of vertebroplasty and kyphoplasty procedures.

Minimally invasive extracavitary approach for thoracic discectomy and interbody fusion: 1-year clinical and radiographic outcomes in 13 patients compared with a cohort of traditional anterior transthoracic approaches.

Object: Open transthoracic approaches, considered the standard in treating thoracic disc herniation (TDH), are associated with significant comorbidities. The authors describe a minimally invasive lateral extracavitary tubular approach for discectomy and fusion (MIECTDF) to treat TDH.

Methods: In 13 patients (5 men, 8 women; mean age 51.
