Bone island and leprosy.

Objective: To determine the incidence of bone islands in leprosy patients.

Design: X-rays of feet and hands of patients with Hansen's disease (leprosy) were reviewed retrospectively. A second group of related age- and sex-matched patients who did not have Hansen's disease was used for control purposes.

Wrist involvement in Hansen's disease.

We performed a neurological and radiological study of the wrists of 58 patients with Hansen's disease and 60 age-matched healthy control subjects. Significant differences (p < 0.01) were found between the groups in the carpal glenoid sector, the radial physeal widening index, the carpal ulnar distance, the carpal index and in distal radio-ulnar discrepancy.

Delayed diagnosis of fatigue fractures in the elderly.

A retrospective study was made of 30 stress fractures in elderly patients engaged in noncompetitive sporting activities, mostly marching and running. Fractures were located exclusively in the lower limbs. In many cases the diagnosis was delayed and in several cases was incorrect because the stress fracture was mistaken for other conditions.
