Most participated in organized sports (58.9%), with sport\/exertional mechanisms being the most common identifiable cause (41.2%). Congenital spinal stenosis (CSS) was present in 20.6%. Mean symptom-to-surgery interval was 9.2\u2009\u00b1\u20098.3\u00a0months. Length of stay was 0.5\u2009\u00b1\u20090.6\u00a0days, median blood loss was 15\u00a0mL, and no durotomies occurred. Initial symptom improvement was reported by 94.1%, and 79.4% returned to prior activities. Over a median follow-up of 20.4\u00a0months, reherniation occurred in 8 patients (23.5%) and reoperation in 6 (17.6%).
