Effective techniques to repair transected muscles are not well described.
We determined the outcome of surgically repaired closed transections
of the biceps muscle with regard to strength, appearance, and patient
We conducted a study on surgical repair of acute traumatic closed
transection of the muscle belly of the biceps brachii in paratroopers.
Muscle fibers and epimysium were sutured with use of running interlocked
stitches as well as modified Mason-Allen stitches. We gathered data
on the supination torque, appearance of the arm, and patient satisfaction.
Nine patients underwent surgical repair and were followed for a mean
of 2.2 years. Three patients, who constituted a comparative group,
had nonoperative treatment of complete transections of the biceps
and were followed for a mean of eleven years.
We found that the patients who had surgical repair had better results
than did those who had nonoperative treatment, with respect to supination
torque (a mean of 11.0 N-m compared with 5.8 N-m, p = 0.0005), appearance
(a mean of 4.6 cm compared with 3.0 cm, according to the cosmetic
visual analog scale; p = 0.000002), and satisfaction (excellent
in all nine patients who had surgical repair and satisfactory in
all three who had nonoperative treatment).
The results after repair of acute traumatic closed transection of
the biceps brachii with the new surgical technique described in
the present study demonstrated a significant improvement in terms
of function, appearance, and patient satisfaction compared with
those after nonoperative treatment.
