Results From the Partnership for Advancement in Neuromodulation Registry: A 24-Month Follow-Up.

Objective: This longitudinal, clinical outcome study was a multicenter, prospective, observational, registry with a 24-month assessment of patients implanted with spinal cord stimulation (SCS) systems for the management of chronic pain of the trunk and/or limbs.

Methods: On informed consent and institutional review board approval, 614 patients from 39 sites were enrolled within 30 days following permanent SCS system implantation. Medication usage, patient-reported pain relief (PRP), categorical ratings of pain relief, pain disability index scores (PDI), quality of life (QoL), and patient satisfaction were assessed at enrollment, 3-, 6-, 12-, 18-, and 24-month postimplant.

Technical strategies and anatomic considerations for parapedicular access to thoracic and lumbar vertebral bodies.

Objectives: To investigate and illustrate a variation on the traditional percutaneous access to the vertebral body via a parapedicular approach.

Design: An effective parapedicular access technique that could safely and reliably guide the needle tip into the center of the vertebral body was developed from cadaver dissection observations for the purpose of clinical use.

Patients: A total of 102 vertebral compression fractures from T-4 to L-5 were treated via the parapedicular access at our institution between July 2005 and March 2006.
