Foot and ankle manifestations of Reiter's syndrome

If one were to characterize the clinical presentation of Reiter's syndrome in the feet and ankles, it would be that of pain associated with mild to moderate swelling and tenderness without significant erythema. These changes would occur most commonly at the posterior calcaneus, metatarsophalangeal joint, and phalangeal regions. The ankles will usually show an effusion. It is very uncommon for the subtalar region, midfoot region, or even the metatarsal shaft area to be involved. Roentgenographic changes were present in similar frequency as in physical findings. Erosions and soft tissue swelling affect the forefoot and ankle while "spurring" and erosions affect the hindfoot. It is readily apparent that no single clinical finding or radiographic change indicates Reiter's syndrome. The type and location of foot pain is what should prompt the physician to seek further elements allowing the diagnosis of Reiter's syndrome.
