Design limitations of Bryan disc arthroplasty.

Background Context: Disc arthroplasty is gaining momentum as a surgical procedure in the treatment of spinal degenerative disease. Results must be carefully scrutinized to recognize benefits as well as limitations.

Purpose: The aim of this study was to investigate factors associated with segmental kyphosis after Bryan disc replacement.

Minimally invasive anterior approach to upper cervical spine: surgical technique.

Objective: The transoral approach of Spetzler is the classic anterior access to the upper cervical spine that provides direct exposure for anterior decompression of the spinal cord. The risks of infection, the limits in extension, and the postoperative recovery difficulties of transmucosal access suggest the use of an alternative anterior extraoral approach in upper cervical surgery. However, this approach results in complications from nerve palsy because of excessive retraction of the hypoglossal and the superior laryngeal nerves.

Posterolateral dislocation of the C1-C2 articulation associated with fracture of the anterior arch of C1: a case report.

Study Design: Case report.

Objective: To report a rare traumatic C1-C2 dislocation associated with fracture of the anterior arch of the atlas in a neurologically intact patient.

Summary Of Background Data: Isolated fractures of the anterior arch of C1 are very rare.

Suspended laminoplasty for wide posterior cervical decompression and intradural access: results, advantages, and complications.

Object: Cervical laminoplasty is a recognized technique commonly used for multilevel posterior cervical decompression, and it is favored over laminectomy for maintaining spinal stability. Traditional hinge techniques, however, limit lateral exposure on one side and can limit dural exposure. The authors present their experience with a modified laminoplasty technique incorporating complete laminectomy and placement of titanium miniplate instrumentation.
