OBJECTIVE: We present a study that aims to clarify the influence of age and time of clinical evolution of symptoms on prognosis after surgery. METHOD: Prospective study of 66 patients who underwent intervention due to SCM, evaluated (mJOA score) before and after surgery. Three-year follow-up. The variables of age and time of clinical evolution (TE) were analyzed. The latter was subdivided into two groups: long-term evolution (> 1 year), with 35 cases and short-term evolution (≤ 1 year), with 31 cases, as well as the variable of recent worsening (RW). Recent worsening, when the disease has progressed gradually, without significant complications, is evaluated as NO (15 cases); in cases of disease progression before the intervention, it is evaluated as YES (20 cases). RESULTS: Age showed a significant correlation with P < 0.01 in preoperative clinical symptoms (r = -0.38) and postoperative symptoms, with P < 0.05 (r = -0.30). No correlation was found between age and recovery rate. TE did not show any correlation with preoperative state. A significant negative correlation was found between time of evolution, postoperative clinical state (r = -0.46) and TR , with P < 0.001 (r = -0.42). TR was 20% longer in patients with short clinical evolution. The variable RW was greater in the preoperative period, 1.45 points on average (mJOA), with statistical significance of p<0.05, and worse recovery rates (10%) than those of the other patients. In RW, though without statistical significance. CONCLUSIONS: Age has a negative influence on pre- and postoperative clinical symptoms, and is not predictive of improvement capacity. Time of evolution is a prognostic value of improvement capacity, and its influence is negative.
