A cross-sectional study was conducted. ⋯ The inner transverse diameter of the lumbar pedicle, particularly in young children, is smaller than previously reported. Insertion of screws currently available commercially screws seems to be safe in the L4-L5 pedicles of children ages 5 to 8 years, and in the L3-L5 pedicles of older children. Custom-made screws might be considered for upper levels for safe application.

An anatomic study of pedicle dimensions and orientation was performed for upper thoracic vertebrae from elderly human subjects. ⋯ Even the largest patients had some pedicles that could not accommodate the smallest standard pedicle screw, and more than one half of the pedicles average patients were too small. Transpedicular screw placement is not safe in these patients. Proper placement must avoid penetration of the medial pedicle wall.

A literature review was conducted. ⋯ Current BT-CBT helps many patients with chronic pain. Continuing clinical research should improve the matching of treatments with patient characteristics and refine the focus of treatments on behavior changes most associated with positive outcome. Further study of fear, attention, readiness to adopt self-management strategies, acceptance of pain, and new combinations of interdisciplinary treatments may lead to improved interventions.

A prospective longitudinal study was conducted to evaluate dysphagia after anterior cervical spine surgery. ⋯ Dysphagia after anterior cervical spine surgery is a common early finding. However, it decreases significantly by 6 months. The minority of patients experience moderate or severe symptoms by 6 months after the procedure. Female gender and multiple surgical levels could be identified as risk factors for the development of postoperative dysphagia.

The literature on diagnostic tests available to the spine clinician for the evaluation of chronic low back pain was reviewed. ⋯ There are inherent limitations in the accuracy of all diagnostic tests. The tests used to diagnose the source of a patient's chronic low back pain require accurate determination of the abolition or reproduction of the patient's painful symptoms.
