CASE REPORT: A 62-year-old woman underwent placement of a permanent SCS after failing conservative therapy to manage her severe CIPN. Preoperatively, she reported significant gait instability in addition to her pain, typically suffering 10 falls per month. Postoperatively, she experienced a pronounced reduction in her pain level from 8 of 10 to 2 of 10 and in her number of falls from 10 to 0 per month. Furthermore, we formally assessed gait speed and function, Timed Up and Go (TUG) testing, postural control, and lower extremity function before and after SCS placement, and we found a profound improvement in all measurements. CONCLUSIONS: For patients with CIPN, SCS devices represent an increasingly viable treatment option. Our patient demonstrated significant improvements in not only pain, but also surprisingly in her motor function and gait stability with SCS therapy. This case highlights a potential additional benefit of neuromodulation in patients suffering from CIPN.

Aggressive CSF drainage to alleviate the IIH headache can inadvertently cause a low-pressure postdural puncture headache (PDPH). CASE REPORT: We report the novel case of a patient with an IIH headache, which was treated with CSF drainage resulting in a PDPH and subsequent return of the IIH headache. Physical examination findings of papilledema and the nonpositional character after the epidural blood patch (EBP), and improvement of symptoms with topiramate and dexamethasone, show that IIH was the likely cause of her post-EBP headaches. CONCLUSIONS: The best-case scenario is to prevent severe cases of PDPH in this patient population. The authors recommend targeting intracranial pressure (ICP) after the treatment of IIH to the high-normal range to prevent PDPH. If IIH headache symptoms arise after EBP, conservative measures to reduce ICP can be utilized, such as acetazolamide, topiramate, and dexamethasone.

While the roof of the cubital tunnel is most often formed by Osborne’s ligament, the anomalous, evolutionary remnant muscle, the anconeus epitrochlearis, has been previously identified as a potential cause of cubital tunnel syndrome. CASE REPORT: A 45-year-old female physical education coach noted bilateral upper extremity pain, numbness, paresthesias, and early onset exercise fatigue originating at the medial elbow and radiating down the ulnar nerve distribution. Sonographic evaluation showed evidence of a hypertrophic anconeus epitrochlearis in the right upper extremity causing compression of an enlarged, bifid ulnar nerve. The patient was treated with 3 separate ultrasound-guided hydrodissection injections, which resulted in complete resolution of her symptoms and a decrease in the ulnar nerve cross-sectional area on sonographic evaluation at 24-week follow-up.
