We previously reported inpatient and 30-day postoperative patient-reported outcomes (PROs) of a controlled, noncrossover pilot study using preoperative mindfulness-based stress reduction (MBSR) training for lumbar spine surgery. Our goal here was to assess 3-month and 12-month postoperative PROs of preoperative MBSR in lumbar spine surgery for degenerative disease. ⋯ Three-month and 12-month results suggest that preoperative MBSR may have pain control benefits in lumbar spine surgery.

Case Reports
Posterior calvarial augmentation for Chiari malformation type 1 refractory to foramen magnum decompression.
Chiari 1 malformation is a structural abnormality of the hindbrain and posterior fossa characterized by herniation of the cerebellar tonsils through the foramen magnum. Although asymptomatic in some cases, hindbrain herniation can be associated with disruption of cerebrospinal fluid flow dynamics at the craniovertebral junction and syrinx formation, leading to symptoms. Foramen magnum decompression with or without duraplasty has been the most commonly performed surgical procedure in the management of this condition. The management of syringomyelia associated with Chiari malformation is more challenging and controversial. Although the associated syrinx can significantly improve after craniovertebral decompression and restoration of cerebrospinal fluid flow, in some cases, it will persist despite decompressive surgery and could even continue to enlarge. ⋯ Posterior calvarial augmentation is a viable option for patients with Chiari malformation refractory to foramen magnum decompression.

Comparative Study
Comparison of radiation exposure between O-arm navigated and C-arm guided screw placement in minimally invasive transforaminal lumbar interbody fusion.
Instrumentation in minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) is highly dependent on image guidance. Guidance with fluoroscopy (C-arm) and cone-beam computed tomography (O-arm) with navigation are common options. The intraoperative radiation exposure to patients with the different image modalities has not been compared, however. The present study aimed to compare the radiation exposure of the C-arm guidance and O-arm navigation techniques during MIS-TLIF surgery. ⋯ For level 1 MIS-TLIF (4 percutaneous screws), patients in the ON group had almost double the radiation exposure as those in the CG group. For level ≥2 (≥6 screws) or obese patients, the O-arm with navigation has the advantage of similar radiation exposure to the patient and less (almost no) radiation to the operating room staff.
