The study goal has been comparative estimation of clinical results in cases, subjected to anterior cervical decompression with an inter-body block and foraminal decompression.
Material and Methods. There were 162 cases with spondylogenic cervical radiculo- and radiculomyelopathy, operated in 1999-2009. Their age varied from 32 up to 68 years. There were 108 males (66.7%) and 54 females (33.3%). The cases were divided into the following groups, depending on a type of operation: group I – anterior cervical decompression with an inter-body block (61 cases; 37.7%); group II – anterior cervical decompression with an inter-body block and foraminal decompression (50 cases; 30.9%): group III – foraminal decompression (51 cases; 31.4%).
Results. A minimum follow-up period was 1 year. Pain syndrome was estimated on the basis of the Visual-Analog Scale. Cases of group I were characterized by slower regression of pain in a neck and hand in comparison with patients of two other groups. One could watch good regression of pain in a hand in cases of group II; however it was slower in a neck. Pre- and postoperative EMS in anterior cervical decompression with an inter-body block were 10.8 and 14.8, respectively. The same indices in foraminal decompression were 11.2 and 14.7, respectively. There were no cases with instability a year after operation, as well as no compression relapses at operated levels. Long-tern neurological outcomes in anterior decompression were comparable with the results, watched in anterior cervical decompression with an inter-body block and reported by other authors.
Conclusion. Foraminal decompression is an effective and little-invasive method of surgical treatment of cases with cervical spondylogenic radiculopathy and radiculomyelopathy. Thorough selection of cases and precision microsurgery are a key to successful surgical treatment.
