Must Have Elbow Flexion • Musculocutaneous Nerve • Innervates: • Coracobrachialis • Biceps • Brachialis whiskeygoldmine.com
Modified Oberlin Thoracodorsal
Double Fascicular Nerve Transfer • Using fascicles from the intact • median nerve • Ulnar nerve
Post Operative Therapy:Musculocutaneous Nerve Transfer • Post-operative pain management • Edema control • Immobilization • 7-10 days • Early ROM • Shoulder, wrist, hand • 3-4 weeks, elbow A/PROM
Motor Reeducation • Motor reeducation with tasks that are normal for elbow flexion are instituted to relearn: • normal movement patterns • muscle recruitment • reestablish muscle balance • 1st: elbow flexion muscle “contraction” combined with contraction from donor nerve: FCU, FCR, FDS and PL • Want most synergistic action based on original motor pattern • Bimanual tasks
Strengthening • Utilize reinnervated muscle physiology and biomechanics • 1) short duration exercise sessions (<5-10min) • Slow onset contractions • begin in mid-range (place and hold) or gravity eliminated • 2) Multi-angle isometrics • 3) Concentric strengthening • 4) Eccentric strengthening
