Dwyer instrumentation

[dwī′ər]
one method for correcting the spinal curvature associated with scoliosis, involving a cable that is inserted to assist in maintaining the corrected curvature while the fusion heals. It is not usually removed unless there is postoperative indication of displacement or a pattern of associated symptoms. Dwyer cable instrumentation involves surgical intervention through the pulmonary cavity and the rib cage and is accompanied by a relatively greater surgical risk than a posterior approach. It is often inadequate to correct the spinal curvature involved and must frequently be followed several weeks later by a posterior spinal fusion.

Dwyer instrumentation

(dwī′ĕr)
[Allan Frederick Dwyer, Australian orthopedic surgeon, 1920–1975]
A surgical procedure for stabilization of scoliosis. The spine is approached from the front, and bolts are inserted transversely through each vertebra. A cable attached to the bolts is applied to the convexity of the curve, and the vertebrae are pulled together.
