phrenic nerve transposition

Radial nerve transposition for the treatment of brachial plexus injury Treatment of diseases: brachial plexus injury Indication Radial nerve transposition is applicable to: 1. Brachial plexus root avulsion injury within 2 years, flexion of elbow tendon, but muscle atrophy is not serious, can still lick the muscle belly. 2. The phrenic nerve function is good. The phrenic nerve is most often located in the musculocutaneous nerve. Surgical procedure Incision V-shaped, transverse or oblique incisions can be used, with V-shaped incisions showing the largest range, and transverse and oblique incisions showing a smaller range. The V-shaped incision starts from the midpoint of the posterior margin of the sternocleidomastoid muscle, along the posterior edge of the muscle down to the intersection of the sternocleidomastoid muscle and the clavicle, and then extends along the upper edge of the clavicle to the junction of the middle and outer 1/3 of the clavicle. The transverse incision is 1.5 cm above the clavicle, centered on the midpoint of the clavicle, parallel to the clavicle, and 5 to 7 cm long. The oblique incision originates from the posterior edge of the midpoint of the sternocleidomastoid muscle and slopes outward to the midpoint of the clavicle. 2. revealing the separation of the phrenic nerve The phrenic nerve was exposed on the surface of the anterior scalene muscle in the incision on the supraclavicular bone. The phrenic nerve was cut under direct vision near the thoracic mouth. The procaine was first closed with procaine before cutting. 3. Reveal the musculocutaneous nerve The musculocutaneous nerve is exposed in the subclavian incision, or the upper anterior sac is exposed in the incision on the supraclavicular bone, and the thickest bundle in the outer front is the musculocutaneous nerve bundle. 4. Sewage nerve The sacral nerve and musculocutaneous nerve are moved in the soft tissue of the clavicle, and the outer membrane is sutured. The suture should be tension-free.
