Practice Patterns of Spine Surgeons Regarding Osteoporosis: An International Survey.

Background: Osteoporosis (OP) represents a great challenge for the spine surgeon. Despite having effective pharmacological treatments for OP and surgical technical innovations, the awareness of spine surgeons regarding OP seems low. The purpose of this research was to assess practice patterns on the diagnosis and treatment of spine surgeons regarding OP.

Prevalence of Poor Bone Quality in Patients Undergoing Spine Surgery: A Comprehensive Approach.

Study Design: A cross-sectional study.

Objectives: To investigate the prevalence of poor bone quality in patients requiring spine surgery through comprehensive evaluation with bone mass density (BMD), trabecular bone score (TBS), FRAX, and vitamin D status.

Methods: we prospectively recruited patients of > 50 years old candidates for lumbar or cervical spine fusion surgery at our institution.

A Rare Case of Negative-Pressure Hydrocephalus: A Plausible Explanation and the Role of Transmantle Theory.

Background: Negative-pressure hydrocephalus is a rare condition with the development of symptomatic hydrocephalus despite subnormal intracranial pressure (ICP). The etiology remains unclear. Some authors proposed that the differential pressure between the ventricular space and the subarachnoid space over cerebral convexity leads to the development of ventriculomegaly, namely as the transmantle pressure theory.

Adjacent-level degeneration after cervical disc arthroplasty versus fusion.

Introduction: The principal objective of this study was to evaluate the incidence of adjacent-segment degeneration (ASD) in patients who underwent cervical disc arthroplasty (CDA) as compared with anterior cervical discectomy and fusion (ACDF).

Methods: It is a prospective cohort study of patients with a single-level cervical degenerative disc disease from C3 to C7 who underwent CDA or ACDF between January 2004 and December 2006, with a minimum follow-up of 3 years. The patients were evaluated pre- and postoperatively with the visual analog scale (VAS), the neck disability index (NDI), and a complete neurological examination.

Dental multisection CT for the placement of oral implants: technique and applications.

Dental computed tomography (CT) is a diagnostic examination for the preoperative evaluation of patients who will undergo placement of oral implants. It can be performed with multidetector CT or more recently with cone-beam CT. The growing older population and the consequent development of edentulism have increased the number of imaging studies performed for preoperative evaluation of dental implantation.
