Ulnar neuropathy and dystonic flexion of the fourth and fifth digits: clinical correlation in musicians.

abstract：:To study causes of obturator neuropathy and to correlate them with outcome, we retrospectively studied patients seen at the Mayo Clinic electromyography (EMG) laboratory from 1975 through 1999 with a diagnosis of obturator neuropathy. Twenty-two patients with obturator neuropathy were identified. The clinical outcome ...
