Posterior interosseous nerve syndrome with hourglass-like fascicular constriction of the nerve.
We describe a case of the posterior interosseous nerve (PIN) syndrome in a patient with gout. Exploration of the PIN revealed multiple hourglass-like constriction of the PIN, which did not correspond to any extrinsic compressing structures. Hourglass-like constrictions of the PIN is one of the causes of the painful PIN syndrome.
