Resistance of primary microsurgical repair of palmar digital nerves to finger mobilization: A cadaver study

Abstract: The aim of this study was to assess the resistance of microsurgically repaired proper palmar digital nerves (PPDN) to mobilization. Thirty-nine PPDN from fresh forearms cadavers were transected and then sutured using 10/0 nylon. After skin closure, each finger was forcefully flexed and ext...

Sumario:Abstract: The aim of this study was to assess the resistance of microsurgically repaired proper palmar digital nerves (PPDN) to mobilization. Thirty-nine PPDN from fresh forearms cadavers were transected and then sutured using 10/0 nylon. After skin closure, each finger was forcefully flexed and extended 10 times. Out of the 39 repaired nerves, two were elongated and four were ruptured; this amounts to a 15.38% complication rate. We recommend immobilization of nerve repairs, although this contradicts most recent studies. Resumen: El objetivo de este trabajo es probar la resistencia de la neurorrafia de los nervios colaterales digitales. Se utilizaron 39 nervios colaterales digitales de 8 antebrazos de cadáver. La sección del nervio se realizó a nivel de la mitad de la falange proximal. La neurorrafia se realizó con Nylon 10-0. Se revisaron los especímenes para constatar el estado de las neurorrafias. Al considerar falla cualquier solución de continuidad o distensión de la zona de sutura se presenta falla de la misma el 15.38%. Los resultados de este estudio llevan a concluir que la inmovilización es necesaria para prevenir la ruptura de la neurorrafia de los nervios colaterales digitales.
