The human foot has been characterized as a miracle of engineering and mechanical efficiency. It is a complex organ, both physiologically and structurally. The authors present a study of the foot and ankle with emphasis on the anatomy of midterm fetuses as revealed by cryomicrotomy.

Physicians have long recognized that systemic diseases manifest themselves in the foot. The podiatric physician can play a crucial role in the identification of such pathologic processes. Consultation with various subspecialties, along with sensory, motor and neurologic examinations often are paramount. This article will present a case of a meningioma identified by careful podiatric evaluation and consultation with internal medicine, neurology, and neurosurgery.

Lupus erythematosus is an enigmatic disease. Its podiatric manifestations are largely cutaneous, but vasculitic involvements may produce complications. The authors review much of the histopathology of lupus erythematosus that is relevant to the podiatric physician and surgeon. Awareness of the serious systemic implications of lupus erythematosus and the internal medications used in treatment is part of the physician's responsibility in understanding the whole patient.

Homologous and heterogenous bone grafting as it might be used in podiatric surgery is reviewed with emphasis on histologic events observed. New bone proliferation, resorption, revascularization, and remodeling are contrasted with autogenous bone grafts, which are generally thought to be the preferred surgical option.
