Thoracoscapular fusion in facioscapulohumeral dystrophy: clinical review of a new surgical method.

A new method of scapulothoracic fusion is described for patients with facioscapulohumeral dystrophy. To improve upper limb function by abolishing scapula winging, bilateral procedures were performed in six patients with an average age of 30 years (range 17 to 44 years). The average follow-up was 49 months (range 1 to 7 years). A good functional and cosmetic result was obtained in all patients. An average postoperative increase in shoulder abduction of 28 degrees and flexion of 40 degrees was seen. Only a small diminution in respiratory function occurred (mean decrease in forced expiratory volume in 1 second of 14% and forced vital capacity of 21%).

Observations on the current and future surgical management of hydatid disease affecting the vertebrae.

Five cases of hydatid disease affecting the vertebrae are described. Clinical features, radiologic appearance, and poor prognosis are emphasized. Four patients had some degree of neurologic deficit at the time of presentation and in three cases there was an increasing kyphosis. In two patients, spinal instrumentation with Harrington apparatus supplemented removal of hydatid material, and its use improved the previous neurologic deficit with stabilization of kyphosis. The antihelmintic drug mebendazole was used in two cases.

Innervation of the lumbar spine.

Back pain, in spinal stenosis, can arise from many sources. Apart from nerve root involvement any of the structures considered above can be implicated. In degenerative conditions, where discogenic and posterior facet pain are present, excess activity tends to increase these symptoms. In addition there is evidence that impulses reaching the spinal nerve root through the sinu-vertebral nerve and possibly the posterior ramus may potentiate the irritability of that root. Whether such a mechanism contributes to the claudication of degenerative spinal stenosis is not known.
