Objective: To determine whether presence of a bone-anchored annular closure device (ACD) impacts reoperation strategies and subsequent outcomes.
Methods: Patients with large annular defects after single-level limited lumbar discectomy were randomly allocated to receive an ACD or discectomy alone (controls) and were followed for at least 3 years.
Results: Among 550 patients, reoperation risk was lower with ACD (11.
Background: Minimally invasive techniques for lumbar discectomy have been recommended as superior to open techniques due to lower blood loss, lower rates of infection and shorter recovery. There are, however, concerns that this approach does not sufficiently remove the herniated nuclear material, thus leaving the patient susceptible to reherniation requiring reoperation. The purpose of this study was to examine the safety and viability of an annular closure device in limiting reherniation and reoperation in a cohort of patients undergoing minimally invasive lumbar discectomy with the assistance of an annular closure device.

- The posterior fossa syndrome (PFS) includes symptoms like cerebellar mutism, behavioral changes, and personality shifts, noted in a 19-year-old patient post-tumor resection.
- Although the patient didn’t experience cerebellar mutism, they developed issues such as apathy, emotional indifference, urinary retention, and visual hallucinations over time.
- Long-term assessments indicated cognitive and emotional deficits similar to those seen in adults with cerebellar cognitive affective syndrome, linked to supratentorial perfusional deficits shown in functional neuroimaging studies.
