Abstract
Introduction: Forearm fractures are the most common long bone fracture in the paediatric population. Associated neurological injury is a well recognized complication of these injuries yet is generally considered to beuncommon. This study sought to evaluate the incidence of neurological impairment in children referred for manipulation by the orthopaedics team in this tertiary referral hospital.
Materials & Methods: A retrospective chart analysis was performed of the first 100 children to be referred for orthopaedic assessment. This represented 43% of the total number of children presenting to the emergency department in this time period. Inclusion criteria involved a fracture of any segment of the radius and/or ulna on radiological examination. Exclusion criteria included concomitant ipsilateral upper limb fracture, and compartment syndrome.
Results: A total of 96 cases met the inclusion criteria. The cohort had a mean age of 8.04. Males were more likely to be injured as was the left forearm. The distal metaphysis was the segment most likely to be fractured and compound injuries were uncommon. The incidence of associated neurological impairment was 15.6%. The median nerve was most commonly injured, comprising 60% of nerve injuries. Distal physeal fractures were the most common fracture pattern to be associated with neurological impairment, with a rate of 37%.
Conclusions: Forearm fractures requiring manipulation in the paediatric population are commonly associated with nerve injuries, with distal physeal fractures having a particularly strong correlation. Clinicians require a high index of suspicion for nerve injury when evaluating forearm fractures to avoid underdiagnosis. Failure to recognize neurological injury at the time of initial assessment has the potential to delay time to reduction due to the injury being misclassified as non-urgent. This delay has the potential to cause a prolonged or failed recovery of nerve function.
