The results in ten arms of nine patients who had post-traumatic tetraplegia at the fifth or sixth cervical level were reviewed after combined transfer of the brachioradialis to the flexor pollicis longus and of the posterior part of the deltoid to the triceps tendon to restore key pinch and extension of the elbow. The average age of the patients was twenty-nine years, the average time from the injury to the operation was five years, and the average duration of follow-up was thirty-one months. Key pinch improved from essentially none preoperatively to an average of 2.0 pounds (0.9 kilogram) postoperatively: an average of 3.0 pounds (1.4 kilograms) for the patients who had tetraplegia at the sixth cervical level and an average of 0.9 pound (0.4 kilogram) for those who had tetraplegia at the fifth cervical level. Key pinch was favorably influenced by extension of the wrist, while the position of the elbow had no effect. Maximum active extension of the elbow against gravity was within 20 degrees of full extension in eight of the ten arms. There was an improvement in the performance of activities of daily living, including wheelchair use, and most of the patients discontinued use of special equipment for the upper extremity. The results of this study, when compared with those of each procedure performed separately, suggest that a combination of the operations improves function of the upper extremity and shortens the duration of dependence postoperatively.
