Bone resorption around the annular closure device during a postoperative follow-up of 8 years.

Objective: Annular closure device (ACD) implantation is considered to be an effective means of preventing reherniation after microdiscectomy; however, there is an issue: the bone may resorb around the ACD. The causes of vertebral bone resorption remain unexplored; the dynamics of changes in bone resorption around the ACD have not yet been assessed or characterized.

Methods: One hundred thirty-three patients underwent ACD implantation after microdiscectomy, and 107 of them were followed up for 8 years after surgery (Oswestry, VAS).

Cervical Disc Degeneration and Vertebral Endplate Defects After the Fused Operation.

Study Design: Longitudinal study of cervical MR in patients with degenerative disc disease (DDD).

Objective: To evaluate the evolution of the degenerative changes in the C2-D1 cervical segments and to assess the association magnetic resonance imaging (MRI) parameters with clinical symptoms after surgical treatment in patients with DDD.

Summary Of Background Data: The evolution of degenerative changes in the cervical spine is poorly understood.

Predictors of Treatment Success Following Limited Discectomy With Annular Closure for Lumbar Disc Herniation.

Background: Previous studies have demonstrated bone-anchored annular closure to significantly reduce reherniation and reoperation rates after lumbar discectomy in patients with large annular defects. It is important to identify the prognostic factors that may be associated with successful treatment. This study aimed to identify predictors of treatment success in patients with lumbar disc herniation treated with limited microdiscectomy supplemented by a bone-anchored annular closure device (ACD).
