Age is the most important predictor of clinical outcome after peripheral nerve injury. The stability of the neuromuscular junction (NMJ) after denervation is thought to be central to neuromuscular recovery. Stability is characterized by maintenance of the motor endplate and mRNA upregulation of the constituent nicotinic acetylcholinergic receptor (nAChR)(More)
Age is an important predictor of neuromuscular recovery after peripheral nerve injury. Insulin-like growth factor 1 (IGF-1) is a potent neurotrophic factor that is known to decline with increasing age. The purpose of this study was to determine if locally delivered IGF-1 would improve nerve regeneration and neuromuscular recovery in aged animals. Young and(More)
Sprengel's deformity is the most common congenital deformity of the shoulder. A known complication of correcting this deformity is brachial plexus palsy. In this study we used somatosensory evoked potential (SSEP) monitoring during correction of a Sprengel's deformity and identified an early iatrogenic brachial plexus injury. The operation was modified, and(More)
