Surgical Results of Lumbar Canal Recalibration by Modified Senegas Technique

Abstract

The aim of recalibration of the lumbar canal using the Senegas technique guarantees stability and preserves movement, with a considerable reduction in surgical risk and faster incorporation into daily life. Objective: To evaluate the surgical results of recalibration of the lumbar canal using the modified Senegas technique. Materials and Methods: An ambispective and cross-sectional descriptive observational study was carried out at the Institute of Neurology and Neurosurgery between January 2011 and December 2019 that were evaluated 6 and 12 months after having been operated. Results: 70.7% of the patients manifested chronic low back pain, and dysesthesia was found in 39.8%. There were 15.8% complications. The clinical evolution according to the Lumbar and Lower Limb Verbal Numerical Scale and the functional one according to the Oswestry Disability Index was better at 6 and 12 months after the intervention compared to the preoperative period. The result was considered good at 82.7% and 89.4%, respectively, at 6 and 12 months. Conclusions: The clinical and functional evolution of the operated patients is significantly better at 6 and 12 months concerning the preoperative one. At both 6 and 12 months, surgical results are good in the vast majority of patients.
