STUDY DESIGN: A prospective and controlled study investigated the relation of @entity121 to @entity158 and disability in @entity1 with @entity890 . OBJECTIVES: To determine the incidence of lower limb @entity121 in @entity890 and its evolution over time after surgery, and to ascertain whether @entity4094 has a prognostic value regarding @entity158 and disability. SUMMARY OF BACKGROUND DATA: Residual sciatica, @entity1643 , and disability are common after lumbar discectomy. Preoperative motor dysfunction corresponding to the afflicted nerve root is often seen. METHODS: The @entity1 in this study were 71 @entity1 , ages 15 to 50 years, with disc prolapse at L4-L5 or L5-S1. Before surgery, then 6 weeks, 4 months, and 12 months after surgery, @entity1643 and @entity158 were estimated on a visual analog scale, and disability was determined according to the Roland-Morris Questionnaire and a designed functional muscle test. RESULTS: Motor function of the sciatic leg frequently was impaired. Inferior outcome of proximal motor tests 6 weeks after surgery predicted @entity158 and disability 1 year after surgery. The mean @entity158 was 59 mm before surgery and 15 mm at 6 weeks, remaining at that level during the follow-up period. The mean disability score was 14.4 before surgery, 8.8 at 6 weeks, and 4.7 at 4 and 12 months, whereas muscle function improved gradually through 1 year of follow-up evaluation. CONCLUSIONS: @entity4094 frequently is present in @entity1 with @entity890 . Sciatica resolves quickly after surgery, whereas disability improves gradually up to 4 months and muscular performance improves throughout the first year. @entity121 in @entity890 has a prognostic value concerning @entity158 and disability.
