Comparative Study
Development of the Neck Pain and Disability Scale. Item analysis, face, and criterion-related validity.
The development and testing of a new comprehensive measure of neck pain and disability, the Neck Pain and Disability Scale. ⋯ The results suggest a highly reliable instrument for evaluating neck pain with at least four underlying dimensions. Further work to address the predictive validity of this new tool are under way.

Case Reports Comparative Study
Recapping T-saw laminoplasty for spinal cord tumors.
A prospective study of patients whose spinal cord tumors were managed surgically with a unique posterior method of removing and replacing the posterior spinal elements using T-saw ("recapping T-saw laminoplasty"). ⋯ Recapping laminoplasty afforded anatomic reconstruction of the vertebral arch after excision of spinal cord tumors. This procedure appears to warrant further evaluation as an alternative to wide laminectomies for exposure of intraspinal tumors.

Comparative Study
Kinematics of the chest cage and spine during breathing in healthy individuals and in patients with adolescent idiopathic scoliosis.
The lung function test by a Plethysmograph enabled calculations to be made of the total lung capacity and vital capacity. A Motion Analysis System (Elite, BTS Inc., Milano, Italy) was used to observe and record chest cage and spinal movements and as to correlate lung function with the chest cage and spine kinematics. ⋯ The range of movement of the chest cage and spine is more limited in the scoliotic cases. This overall stiffness of the chest cage and the spine may contribute to the mechanical inefficiency and impairment of pulmonary function found in scoliotic patients.

Comparative Study
The efficacy of using an image-guided Kerrison punch in performing an anterior cervical foraminotomy. An anatomic analysis.
This study comprised two parts: first, a feasibility study to determine the efficacy of using an image-guided Kerrison punch while performing a foraminotomy during an anterior cervical decompression and, second, an anatomic analysis using vector measurement to determine the distance from the entrance of the neuroforamen to the medial margin of the vertebral artery in the subaxial cervical spine. ⋯ An image-guided Kerrison punch may be used successfully when performing cervical foraminotomies during an anterior cervical discectomy, thus eliminating the risk of potential vertebral artery injury. These data confirm previous findings by other authors. Knowledge of these data may aid the spine surgeon in performing a foraminotomy during anterior cervical decompression.
