Abstract
We reviewed 28 patients with brachial plexus lesions caused by shoulder dislocation. Contrary to most other reports, we found that the neurological lesions involved the infraclavicular and the supraclavicular brachial plexus. With supraclavicular lesions the involvement was always of the suprascapular nerve, and this always recovered spontaneously. Isolated axillary nerve lesions had the poorest prognosis for spontaneous recovery. We explored all lesions that showed no recovery after three to five months and performed either grafting or neurolysis. We discuss the combinations of nerve lesions, their recovery, the surgical indications, and the operations. We also suggest a new classification for these injuries which is more clinically relevant than the anatomical classification of Leffert and Seddon (1965).
