The current authors retrospectively reviewed 147 lower extremity peripheral nerve procedures in 114 @entity1 (average age, 42 years) with chronic lower extremity @entity9 to determine whether surgical treatment based on an empirically derived algorithm could reduce @entity158 and improve function. This algorithm assigns crush, stretch, and chronic transection injuries to treatment with transection and containment. Peripheral nerve stimulation was used in conjunction with transection and containment for @entity1 with more chronic presentations for whom previous transections had been unsuccessful. @entity1 with @entity9 underwent revision neurolysis with vein wrapping. @entity1 with repetitive nerve @entity130 (overuse) underwent primary or revision neurolysis. Duration of symptoms averaged 37 months, and mechanisms of @entity128 included chronic transection, crush, @entity9 , stretch, repetitive @entity130 , and idiopathic etiology. Time to followup averaged 38 months. @entity158 and dysfunction were ranked from 0 points (no @entity158 ) to 10 points ( @entity158 prompting request for amputation or functional deficit warranting wheelchair use); preoperative and followup work status were documented. Average @entity158 and dysfunction scores improved: 8.8 to 5.6 points and 7.6 to 5.0 points, respectively. Of the 114 @entity1 , 52 (46%) @entity1 improved their work status, including 35 of 87 (40%) involved in workers' compensation. There were no statistically significant differences in outcome based on mechanism of @entity128 or type of procedure. The consistent average improvement suggests this algorithm assigns the appropriate procedure to a given mechanism of injury.
