Repeat, Bilateral Femoral Nerve Blocks With Liposomal Bupivacaine for Analgesia in a Patient With Calciphylaxis: A Case Report.

A 39-year-old woman with juvenile idiopathic arthritis complicated by nonuremic calciphylaxis presented for pain management of bilateral lower extremity wounds requiring frequent dressing changes. Bilateral single-shot femoral nerve blocks using liposomal bupivacaine and 0.25% bupivacaine were performed. The patient reported decreased pain scores and had reduced opioid use for 72 hours postblock. Repeat, bilateral single-shot femoral nerve blocks with liposomal bupivacaine and 0.25% bupivacaine were performed approximately every 72 hours to maintain adequate analgesia. We conclude that off-label use of liposomal bupivacaine in femoral nerve blocks results in prolonged block duration without adverse effects or tachyphylaxis.

Transient Right-Sided Hemiparesis and Diplopia in the Setting of a Migrated Cervical Spinal Cord Stimulator Lead: A Case Report.

A 36-year-old man with a history of cervical spinal cord stimulator (SCS) lead placement presented with transient right-sided hemiparesis and diplopia that began 2 days after a coughing episode. Imaging revealed lateral and cranial migration of one of the patient's SCS leads. Deactivation of the SCS resulted in rapid improvement of his nonmotor symptoms but did not resolve his motor deficits. The SCS system was surgically explanted, resulting in resolution of the patient's motor symptoms. The unique neurologic symptomatology demonstrated by this patient is a previously undescribed complication of SCS placement and lead migration.
