Surgical Management of Nerve Injuries Caused by Pediatric Upper Extremity Fractures

While most nerve injuries associated with fractures resolve on their own, there is limited literature regarding the optimal management of persistent palsies. This review outlines nonoperative treatment strategies and provides guidance on the indications and management of cases when surgery is necessary for major upper extremity nerve injuries. It covers indications and techniques for surgical exploration, neurolysis, nerve repair, resection with grafting, and late reconstruction options. We synthesize the existing pediatric and adolescent literature and pertinent adult studies. Furthermore, we share the extensive clinical expertise of the authors, all of whom specialize in pediatric hand and upper extremity surgery.

(1)Associated nerve injuries following pediatric upper extremity trauma are uncommon, yet optimal upper extremity function is dependent on prompt diagnosis and referral to a team of hand surgeons and therapists.(2)Understanding the potential mechanisms/locations of injury and the natural history will enable these teams to diagnose and prognosticate outcomes efficiently.(3)Physical examination, nerve conduction studies, radiographs, ultrasound, and advanced imaging (MRI) are often required.(4)Treatment of nerve deficits can include combinations of observation, neurolysis, nerve repair, nerve grafting, nerve transfer, and muscle transfer.
