Ardeshiri A, et al. - Among patients at high risk of herniation recurrence treated in routine clinical practice, researchers tested the effectiveness and safety of limited lumbar discectomy with additional implantation of an annular closure device (ACD). According to this prospective, single-center study, the cumulative event incidence through 2 years was 4.0% for reoperation and 1.4% for herniation recurrence among 75 high-risk patients (mean age 45 years). The mean severity of leg pain decreased from 73 to 6, the severity of back pain decreased from 51 to 13, and Oswestry Disability Index (ODI) fell from 49 to 7. The percentage of patients who reached the minimum significant difference were 91% for leg pain, 65% for back pain, and 94% for ODI. Additional implantation of an ACD was safe and reherniation recurrence rates were low in patients at high risk of herniation recurrence following limited lumbar discectomy in routine clinical practice at 2-year follow-up, which is favorably compared with reported rates in high-risk patients.
