| ABSTRACT |
|
To determine the effects of decompressive surgery on neurological outcome following incomplete cord injury of the mid and lower cervical spines, 44 patients(decompression and stabilization group: stabilization or conservative treatment group=21:23) who underwent operations between 1993 and 1995 were retrospectively reviewed. We compared neurological outcome by Frankel's grade, Prolo economic and functional rating scale, and final ambulatory status between two groups. Also, we analysed MRI findings related to neurologic outcome in these cervical cord injured patients. With regard to upgrading scale by Frankel's grade, decompressive surgery group was more improved(98% vs 78%). With regard to Prolo's scale, decompressive surgery group were excellent in 24%, good in 52%, and fair in 24%. Stabilization only or conservative treatment group were as follows: excellent(22%), good(39%), fair(30%), and poor (9%). In the viewpoint of walking status, the result of decompressive surgery group was better(90% vs 74%). Initial MRI findings and neurological assesment correlated with neurological recovery. In conclusion, decompressive surgery may be more effective in patients with incomplete cord injury on mid or lower cervical spines when there are cord compressive lesions such as traumatic disc herniation, spondylotic spur, bony impingement in the spinal canal, and irreducible spinal malalignment unless major intramedullary hemorrhage is present. |
