OUTCOME ANALYSIS OF LUMBAR LAMINECTOMY WITH NONINSTRUMENTED ARTHRODESIS IN LUMBAR SPONDYLOLISTHESIS

Abstract

Decompressive lumbar laminectomy is often necessary in the treatment of symptomatic patients who have degenerative spondylolisthesis and spinal stenosis. This article reported the technique and outcomes of decompressive lumbar laminectomy with noninstrumented arthrodesis in Phichit Hospital by reviewed medical record of 67 patients who were operated from 1998 to 2003. The outcomes of the treatment method based on the Prolo Functional Economic Outcome Rating Scale to improve the ability were compared with other series. Most of patients were farmer (43.28%). Sixty - three patients (94.04%) had good outcomes as defined by score 7 – 10, four patients (5.96%) had fair outcomes. We can concluded that decompressive lumbar laminectomy with noninstrumented arthrodesis could be an alternative choice for lumbar spondylolisthesis which had good outcomes, inexpensive and available in general hospitals.
