Surgical strategy in extensive proximal brachial plexus palsies

Abstract

Purpose

To describe and assess an overall surgical strategy addressing extensive proximal brachial plexus injuries (BPI).

Methods

Forty-five consecutive patients’ charts with C5–C6–C7 and C5–C6–C7–C8 BPI were reviewed. Primary procedures were nerve transfers to restore elbow function and grafts to restore shoulder function when a cervical root was available; when nerve surgery was not possible or had failed, tendon transfers were conducted at the elbow while addressing shoulder function with glenohumeral arthrodesis or humeral osteotomy. Tendon transfers were used to restore finger extension.

Results

Forty-one patients underwent elbow flexion reanimation: thirty-eight had nerve transfers and eight received tendon transfers, including five cases secondary to nerve surgery failure; grade-3 strength or greater was reached in thirty-seven cases (90%). Twenty-nine patients had nerve transfers to restore elbow extension: twenty-five recovered grade-3 or grade-4 strength (86%). Forty-one patients underwent shoulder surgery: fourteen had nerve surgery and thirty-one received palliative procedures, including four cases secondary to nerve surgery failure; thirty patients recovered at least 60° of abduction and rotation (73%). Distal reconstruction was performed in thirty-seven patients, providing finger full extension in all cases but two (95%).

Conclusions

A standardized strategy may be used in extensive proximal BPI, providing overall satisfactory outcomes.
