Slide 10 Cannot Be Fixed Neurotization Tendon Transfer Joint fusion Slide 11 Slide 12 Can Be Fixed Primary Repair Nerve Grafting Neurotization Tendon Transfer Free Muscle Flap Joint Fusion
Slide 13 NEURAPRAXIA Stretching of nerve Results in nerve dysfunction Demyelination Function returns by 3 months NEUROTMESIS Significant nerve damage Nerve division No recovery Nerve repair required Slide 14 Primary Repair Interposition Graft Neurotization Slide 15
Slide 16 Slide 17 If a cut nerve cannot find its mate a painful neuroma may result Slide 18 CRPS is often a misdiagnosed occult neuroma
Slide 19 Slide 20 Sural Nerve Antebrachial Cutaneous Nerve Cervical Plexus Posterior Interosseous Nerve Nerve Conduit Allograft Slide 21
Slide 22 Slide 23 Take a functioning nerve to a less important muscle, and attach it to a more important muscle. Spinal accessory branches Buccal branches Intercostal nerve Nerve to subclavius m. Contralateral Nerves Slide 24
Slide 25 Slide 26 Slide 27
Slide 28 Slide 29 Slide 30 When nerve repair is required, recovery is delayed 1-2 Month Latency Nerve Growth 1 mm/day 1 inch/month Longer Distance, Longer Recovery Time
Slide 31 Diagnosis Work-up Nerve Studies Nerve Repair Post-op Care Rehabilitation Slide 32 PRELIMINARY WORK UP STARTS RIGHT AWAY Slide 33 FIRST EMG AT 6 WEEK TO 3 MONTHS
Slide 34 3 months nothing clinically or by EMG Repeat EMG at 6 months if no improvement If no improvement operate. If improvement Reassess at 9 months Slide 35 Nothing by EMG or clinically at 3 months Slide 36 Minimal Progress by EMG or clinically at 6 months
Slide 37 Not completely improved by 9 months Slide 38 Brachial Plexus Repair Slide 39
