Facet Arthropathy

Chronic neck pain is a common cause of functional impairment in the general population. A significant percentage has a component of cervical facet arthropathy for which cervical radiofrequency ablation (RFA) has been successful in treating. We present a case of spinal accessory nerve (SAN) palsy after water-cooled cervical RFA. A 37-year-old female with history of fibromyalgia and occipital neuralgia presented with cervicalgia. Magnetic resonance imaging (MRI) revealed degenerative changes and central canal stenosis at C5-6. After positive result to diagnostic cervical medial branch blocks (MBB), she underwent staged bilateral C2-3-4-5 medial branch watercooled RFA. On subsequent follow up, she noted new left shoulder pain. On exam, difficulty with left arm abduction and scapular winging was noted. Electrodiagnostics (EDX) revealed mild denervation and mild decreased motor units on needle EMG study. Nerve stimulation study of the SAN to the upper trapezius revealed latency prolongation and amplitude reduction, consistent with an acute spinal accessory neuropathy. Repeat EDX study, 7 months later, no longer showed denervation in upper trapezius, normal latency, and improved (although still decreased) amplitude. SAN palsy after multilevel cervical RFA has not been reported in the literature to our knowledge. Cervical RFA is generally considered safe with most complications being transient and minor with no lasting adverse effects. Spinal accessory nerve palsy is one cause of scapular winging. This case highlights the importance of physical exam and knowledge of anatomical structures in promptly diagnosing SAN palsy. Key words: Spinal accessory nerve palsy, medial scapular winging, lateral scapular winging, cervical radiofrequency ablation, cervical facet arthropathy, cervical medial branch blocks, cervicalgia, water-cooled radiofrequency ablation

Abstract BACKGROUND Traumatic brachial plexus injuries cause long-term maiming of patients. The major target function to restore in complex brachial plexus injury is elbow flexion. OBJECTIVE To retrospectively analyze the correlation between the length of the nerve graft and the strength of target muscle recovery in extraplexual and intraplexual nerve transfers. METHODS A total of 51 patients with complete or near-complete brachial plexus injuries were treated with a combination of nerve reconstruction strategies. The phrenic nerve (PN) was used as axon donor in 40 patients and the spinal accessory nerve was used in 11 patients. The recipient nerves were the anterior division of the upper trunk (AD), the musculocutaneous nerve (MC), or the biceps branches of the MC (BBs). An index comparing the strength of elbow flexion between the affected and the healthy arms was correlated with the choice of target nerve recipient and the length of nerve grafts, among other parameters. The mean follow-up was 4 yr. RESULTS Neither the choice of MC or BB as a recipient nor the length of the nerve graft showed a strong correlation with the strength of elbow flexion. The choice of very proximal recipient nerve (AD) led to axonal misrouting in 25% of the patients in whom no graft was employed. CONCLUSION The length of the nerve graft is not a negative factor for obtaining good muscle recovery for elbow flexion when using PN or spinal accessory nerve as axon donors in traumatic brachial plexus injuries.
