Treatment of recurrent metatarsalgia by neuroma resection and muscle implantation: case report and proposed algorithm of management for Morton's "neuroma".

This report describes the theoretical basis for an approach to treating a recurrent Morton's "neuroma." The recurrence, being a true, classic neuroma, is treated by a technique validated in the treatment of the upper extremity painful neuroma: neuroma resection and muscle implantation. A plantar approach, implanting into the deep layer of intrinsics, was used. The three year success of this technique in a long-distance runner is reported.

Morton's metatarsalgia. Light and electron microscopic observations and their relation to entrapment neuropathies.

The dissected plantar nerves of 105 patients with clinical symptoms of Morton's disease were examined under light and electron microscopy. Of the 105 cases, 75 showed characteristic neuronal lesions; in the others different pathologic substrates responsible for the clinical symptoms could be demonstrated. The nervous lesions are characterized by: 1. Thickening of the walls of the endoneurial vessels produced by multiple layers of basement membranes. 2. Edema and sclerosis of the endoneurium. In the electron microscope the endoneurium was filled by deposits of fibrils with a tubular substructure and a diameter of 100-110 A. 3. Thickening of the perineurium. 4. Degeneration of the nerve fibers without signs of wallerian degeneration or obvious reactive Schwann's cell hyperplasia. The possible pathogenetic mechanisms of Morton's disease and some clinical problems are discussed.

Considerations in metatarsalgia and midfoot pain: an MR imaging perspective.

There are many conditions that have the potential to produce the symptom of pain in the metatarsal and midfoot regions. Pathologic processes that cause pain include post-traumatic disorders, circulatory disorders, arthritides, neuroarthropathy, and conditions that result in a biomechanical imbalance in the foot. Magnetic resonance (MR) imaging is a powerful imaging tool since it provides a noninvasive method for diagnosis of different foot disorders. In this article, we will discuss the MR manifestation of a number of pathologic entities that elicit foot pain as a primary symptom.

Bone marrow edema of the forefoot after chevron osteotomy--a rare cause of metatarsalgia: a case report.

Treatment options of bone marrow edema syndrome, which is associated with vascular disturbances, are protracted nonoperative treatment or core decompression which still demands several weeks until complete recovery. We obtained excellent results by the use of the vasoactive drug iloprost, a stable prostacyclin analogue, leading to a complete relief of symptoms in cases of bone marrow edema which had initially suggested early avascular necrosis of the second metatarsal head. The bone marrow edema of the second metatarsal bone was thought to be due to altered biomechanics following a distal first metatarsal chevron osteotomy. During the five days of iloprost infusion, the patient reported relief of rest pain. After therapy, the pedobarogram was normalized. The AOFAS forefoot score improved from 44 to 85 points after one month, and to 95 points after three months. At that time, the marrow showed normal signals. Without additional intervention the patient was able to resume normal activities.
