Previously published studies on transfers to restore elbow flexion hav
e rarely compared the outcomes among different techniques. We found no
comparison between the Steindler procedure and pectoralis major tendo
n transfer. This study compared functional outcomes after these two ty
pes of elbow flexorplasty performed in conjunction with shoulder arthr
odesis for patients with brachial plexus injuries. The same examiner a
ssessed 14 patients who underwent shoulder fusion and elbow flexorplas
ty. Five had a pectoralis major tendon transfer, and nine underwent a
modified Steindler procedure. All patients had brachial plexus lesions
that were irreparable or had not responded to neurolysis, repair, or
grafting. Average follow-up time was 60 months (range, 12 months-10 ye
ars). All patients completed a questionnaire (pain, function) and unde
rwent an objective assessment of range of motion, isometric strength,
isotonic power, grip, and pinch strength. The BTE Work Simulator (Balt
imore Therapeutic Equipment, Hanover, MD) was used for muscle strength
testing. Improvement was noted in daily activities including dressing
and bilateral activities and was reflected in a significant improveme
nt over preoperative function. No differences (at p = .05 level of sig
nificance) were found in objective tests between the pectoralis major
transfer and the Steindler groups. In the patient requiring stabilizat
ion of the shoulder and flexorplasty, the pectoralis major tendon tran
sfer was at least equivalent to the modified Steindler flexorplasty in
terms of range of motion, strength, and subjective measures.
