Nail and hyperkeratotic problems in the elderly foot.

Subungual hemorrhage, onychauxis, onychogryphosis, mycotic infections, onychia and paronychia are common toenail disorders in the elderly. The many contributing factors include impaired vision, changes in gait, past foot conditions and neurovascular disease. Hyperkeratotic disorders are secondary to external or internal pressure. Many of these foot problems are chronic conditions and require continuing management for relief. If improperly treated, some conditions may lead to amputation.
