Osteoarthritis involving the metatarsophalangeal joints and management of metatarsophalangeal joint pain via injection therapy.

Osteoarthritis is one of the most common conditions affecting the foot. It is a common cause of metatarsophalangeal (MTP) joint pain. In this article, the disease process is discussed with respect to its clinical appearance and its relationship to MTP joint pain. A simple diagnostic test is described to help differentiate mechanical MTP joint pain from true joint pathologic conditions and a technique to control MTP joint pain via injection therapy is presented.

Endocrine disorders which manifest in the lower extremity.

This article has attempted to alert the podiatric medical practitioner to those endocrine disorders which have pedal manifestations. With the clinical information presented here, the podiatrist is in a unique position to identify early signs of endocrine disease. By doing so, the podiatric practitioner may play a vital role as a member of the primary care team.

Abnormal biomechanics of feet and their cause of hyperkeratoses.

A brief review of pedal anatomy and the mechanisms enabling feet to function as organs of locomotion is presented. The importance of the subtalar joint is emphasized. Four major abnormalities disturbing normal foot function are noted, and the most commonly encountered of these alterations, rearfoot varus, is discussed in some detail. A series of pedal abnormalities in rearfoot varus occurs because in the foot's attempt to overcome its imbalance, it pronates excessively and causes development of callus, corn, hallux valgus, and even ingrown toenail. Haglund's deformity, soft corn, and tailor's bunion are also secondary to the abnormality. Attempts to restrict the germinal compensatory pronation by various forms of padding of the medial aspect of the foot are frequently rewarded by restoration of asymptomatic feet. Surgical means of restoring normal function are briefly discussed.

Chondroid syringoma in a toe.

The second case of chondroid syringoma in a toe is presented. The diagnosis was confirmed microscopically, and histochemical studies suggested the presence of heavily sulfated stromal acid mucopolysaccharides. Glycogen was present only in some tumor cells. Keratin-containing tumor cells and nests were seen with polarization. This tumor should be considered in the differential diagnosis of painless, slow-growing, pedal tumors.
