Impact of Nerve Surgery on Opioid and Medication Use in Patients with Chronic Nerve Injuries

Background: Peripheral nerve injuries may result in pain, disability, and decreased quality of life (QoL). Pain is an incompletely understood experience and is associated with emotional and behavioral qualities. We hypothesized that pain following peripheral nerve surgery could be predicted by changes in emotions or QoL postoperatively. Methods: Using prospectively collected data, a retrospective study design was used to evaluate the relationships among pain, QoL, and psychosocial factors in patients who underwent peripheral nerve surgery. Patients completed questionnaires rating pain; impact of pain on QoL, sadness, depression, frustration, anger, and hopefulness before surgery; and each postoperative follow-up visit. Multilevel modeling was used to assess the concurrent and lagged relationships between pain and psychosocial factors. Results: Increased pain was concurrently associated with decreased hopefulness ( P = .001) and increased the impact on QoL, sadness, depression, and anger ( P < .001). In lagged analyses, the impact on QoL and anger prospectively predicted pain ( P < .001 and P = .02, respectively). Pain predicted subsequent scores of QoL, sadness, depression, anger, and hopefulness ( P < .01). Having an upper limb nerve injury and self-report of “no comment for childhood trauma” were predictors of postsurgical pain. Conclusion: Psychosocial measures and pain are reciprocally related among patients who underwent surgery for peripheral nerve injuries or compression. Our study provides evidence of the important relationships among psychosocial factors, pain, and outcome and identifies treatment targets following nerve surgery.

Abstract Complication avoidance during peripheral nerve surgery has received little attention in the neurosurgical literature. The goal of our two-part review is to discuss these possible complications, with this initial article highlighting the pitfalls associated with pre- and intraoperative assessment of nerve injuries, as well as the operative nuances used during brachial plexus exploration to minimize complications.

Rating Process

Abstract The AMAGuides to the Evaluation of Permanent Impairment (AMA Guides), Sixth Edition, does not provide a separate mechanism for rating spinal nerve injuries as extremity impairment; radiculopathy was reflected in the spinal rating process in Chapter 17, The Spine and Pelvis. Certain jurisdictions, such as the Federal Employee Compensation Act (FECA), rate nerve root injury as impairment involving the extremities rather than as part of the spine. This article presents an approach to rate spinal nerve impairments consistent with the AMA Guides, Sixth Edition, methodology. This approach should be used only when a jurisdiction requires ratings for extremities and precludes rating for the spine. A table in this article compares sensory and motor deficits according to the AMA Guides, Sixth and Fifth Editions; evaluators should be aware of changes between editions in methodology used to assign the final impairment. The authors present two tables regarding spinal nerve impairment: one for the upper extremities and one for the lower extremities. Both tables were developed using the methodology defined in the sixth edition. Using these tables and the process defined in the AMA Guides, Sixth Edition, evaluators can rate spinal nerve impairments for jurisdictions that do not permit rating for the spine and require rating for radiculopathy as an extremity impairment.
