[Study of peripheral nerve injury in trauma patients].
OBJECTIVE
To determine the prevalence, location, mechanism, and characteristics of peripheral nerve injury (PNI) in trauma patients.


METHODS
A retrospective study of medical records with PNI diagnosis secondary to trauma in the period of 2008-2012. The following information was collected: gender, age, occupation, anatomic location, affected nerve, mechanism of injury, degree of injury, costs, and hospitalization time.


RESULTS
The prevalence of PNI is 1.12%. The location of the nerve injury was 61% upper limb, the highest incidence was presented to the brachial plexus (35%) and ulnar nerve (18%). The mechanism of the lesion was sharp injury (19%).


CONCLUSIONS
The PNI are commonly present in people of a productive age. Neurotmesis was the most frequent degree of lesion. The patients stayed at hospital 2.51 ± 1.29 days and the average cost was 12,474.00 Mexican pesos ± 5,595.69 (US$ 1,007.54 ± 452.21) for one nerve injury.
