An approach to the supraclavicular and infraclavicular aspects of the brachial plexus

Abstract

The surgical approach to the brachial plexus is of great importance during surgery for brachial plexus injuries--obstetric or traumatic. A number of different approaches have been described over the years for these injuries, with each 1 having its own advantages and disadvantages. We describe a novel approach to the supra-clavicular and infra-clavicular aspects of the brachial plexus, which has been used by senior author successfully for the past 15 years. It involves creation of 2 windows, 1 above and 1 below the clavicle in case of adult traumatic plexus injuries. A slight variation of joining the 2 incisions and creation of a laterally based cervicopectoral flap is used for obstetric brachial plexus injuries along with the use of clavicular osteotomy. The advantages of this approach are that it gives rapid access to the brachial plexus; wide exposure can be obtained for all regions of the plexus and donor nerves such as the spinal accessory nerve can be harvested in the same incision.
