Silicone lymphadenopathy associated with failed prosthesis of the hallux: a case report and literature review.

Three years after replacement of a first metatarsophalangeal joint with a silicone prosthesis, a tennis player developed an enlarged ipsilateral femoral lymph node. The implant was also noted to have failed. Fine needle aspiration of the node revealed a foreign body giant cell reaction to particulates morphologically compatible with silicone elastomer. This finding suggests the potential utility of fine needle aspiration in the evaluation of patient response to foreign materials used in prosthetic devices. The lymphadenopathy also suggests that prosthetic metatarsophalangeal replacement in patients with high demand activities run the risk not only of failure of the prosthesis, but also of central migration of the particulate debris resulting from silicone elastomers.

Neurapraxia of the femoral nerve in a modern dancer.

We have presented a case of an acute onset femoral nerve neurapraxia in a pure modern dancer. Repeated mild stretching of the femoral nerve during an established dance routine over a period of several months is implicated as the etiology. The thigh muscles quickly weakened, but regained strength within 3 months. Electromyographic evidence of specific femoral nerve injury initially was negative, but was evident 6 weeks following injury. Overuse syndrome in dancers can cause rapid loss of strength. Other conditions such as herniated intervertebral disc, acute hemorrhage, trauma, iliopsoas rupture, and acute stretching must be ruled out. Complete recovery was the natural outcome.

The stabilizing role of the lateral ligament complex around the ankle and subtalar joints.

The stabilizing role of various ligaments in the lateral side of the ankle and hindfoot was examined experimentally and sequentially using 10 fresh amputated lower limbs. The anterior talofibular ligament contributed to ankle stability in plantarflexion and the calcaneofibular, the fibulotalocalcaneal, and posterior talofibular ligament in all positions. The lateral root of the inferior extensor retinaculum contributed to subtalar stability in neutral and dorsiflexion. The calcaneofibular, fibulotalocalcaneal, and cervical ligaments and the ligament of the anterior capsule of the posterior talocalcaneal joint and the interosseous ligaments contributed to subtalar stability in all positions. The subtalar joint accounted for upward of 50% of ankle/hindfoot inversion after ligament division in the intermalleolar plane.

Fine needle aspiration cytology of silicone lymphadenopathy in a patient with an artificial joint. A case report.

Three years after replacement of the left first metatarsophalangeal joint with a silicone prosthesis, a patient noted enlargement of a left femoral lymph node. Fine needle aspiration of the node revealed a foreign body giant cell reaction to particulates morphologically compatible with silicone elastomer. This finding suggests the potential utility of fine needle aspiration in the evaluation of patients' responses to a variety of foreign materials used in prosthetic devices and as pharmaceuticals.
