title: Abnormal extension of the big toe as a cause of ulceration in diabetic feet.
abstract: Relief from external pressure and repetitive stress is a main concept in treating diabetic neuropathic ulcers. Ulcers on the tip of the big toe may be caused by abnormal extension of the big toe, which can be diagnosed only by observing the patient during barefoot walking. A flexor pad underneath the big toe eliminates the phenomenon, but in case of rigidity of the toe, extremely roomy toe boxes must be prescribed. Out of a series of 272 diabetic patients with skin lesions on the feet 18 suffered this phenomenon, in one case with bilateral ulcerations. Fifteen ulcers healed and below the knee amputation had to be carried out in 4 legs due to ischaemia.
