【Abstract】 Objective To determine whether transfer of ipsilateral cervical 7 root is an effective and reliable procedure in treatment of upper trunk avulsion of brachial plexus. Methods Four patients with C 5～C 6 preganglionic injury were involved between February 1998 and September 2000, who have been undertaken transfer of ipsilateral C 7 root. Transfer of accessory nerve to suprascapular nerve was simultaneously done in 2 of them. Results During the follow up (1 to 2.5 years) period , restoration of biceps has been obtained M 4 in all cases, and shoulder abduction 15° in 1, 45° in 1,> 90° in 2. No remarkable impairment has been found in all C 7 innervated muscles except for decrease of muscle power of one grade at short term. Conclusions This new technique shows promise as an efficacious and safe treatment for upper trunk injuries of brachial plexus. However, it should be prudent when incomplete injuries of lower trunk are involved.更多还原
