The purpose of this prospective randomised study was to evaluate which operative technique for treatment of cubital tunnel syndrome is preferable: subcutaneous anterior transposition or nerve decompression without transposition. This study included 66 patients suffering from pain and/or neurological deficits with clinically and electromyographically proven cubital tunnel syndrome. Thirty-two patients underwent nerve decompression without transposition and 34 underwent subcutaneous transposition of the nerve. Follow-up examinations evaluating pain, motor and sensory deficits as well as motor nerve conduction velocities, were performed 3 and 9 months postoperatively. There were no significant differences between the outcomes of the two groups at either postoperative follow-up examination. We recommend simple decompression of the nerve in cases without deformity of the elbow, as this is the less invasive operative procedure.

The observed effect had a definite dependence on dose, volume, and time after treatment.

In Crohn's disease, some concomitant neurological illnesses such as cerebral ischemia following arterial or venous thrombosis, subacute combined degeneration of the spinal cord following malabsorption of vitamin B12 or folic acid, opticus neuropathy, and polyneuropathy have been described. Cerebral vasculitis secondary to Crohn's disease seems to be a very rare phenomenon. We report on three such cases in three female patients (aged 26, 29, and 61 years). All patients became symptomatic with a hemiparesis; one complained additionally of a speech disorder, headache, and intermittent loss of orientation. In CT and MRI scans, multiple lesions were detected; cerebral angiography showed multiple stenoses of middle- and large-sized vessels that were compatible with cerebral vasculitis. Serologic tests concerning vasculitis were inconspicuous at that time. Under anticoagulation (in two cases) and immunosuppressive therapy, neurologic symptoms disappeared. In the following 6 to 12 months, no new neurological symptoms appeared. In two cases, Doppler sonographic controls showed stationary and, in one case, progressive intracranial stenoses. Since autoimmunologically caused inflammatory bowel diseases might be associated with vasculitis of other organs, the appearance of cerebral vasculitis secondary to Crohn's disease is a possible organ manifestation by inflamed vessels.
