BACKGROUND: Gunshot wounds and blast injuries to the upper limbs produce complex wounds requiring management by multiple surgical specialities.
AIM: We sought to determine the pattern of peripheral nerve injuries among Iraqi soldiers in the war.
METHODS: We performed a 3 year retrospective cohort analysis based on medical records of patients with sustaining gunshot wounds and blast injuries to the upper limbs. Ethical approval was obtained from the institutional review board. The patients included were male, serving military personnel of all age groups and ranks presenting with weakness or sensory loss of radial nerve. Three hundred eighteen patients aged 24 years or older with a high-energy, diaphyseal fracture of the humerus and complete motor and sensory radial nerve palsy were reviewed retrospectively. In these patients, the physical examination and electrodiagnostic study were carried out by experienced neurologists. Seddon's classification system was used to assess the severity of the injury. The data related to the types of fracture, the type of damage, the factors causing damage and the failure of treatment were entered into the IBM SPSS 23 software after extraction of files. Based on mid-range indicators and data distribution, traumatic injuries among Iraqi soldiers in the war against ISIL were then investigated.
RESULTS: A group of 318 patients with mean age of 25.41 ± 6 years were enrolled in the study, of which 127 patients were included with an open fracture and 191 patients with closed lesions. All 127 patients with a transected radial nerve had an open humerus fracture and were part of a complex upper-extremity injury. 113 of 127 subjects had primary repair of the radial nerve and recovered well. 14 of 127 subjects were not recovered. 3 of them had iatrogenic radial nerve injury due to the internal fixation device. Furthermore, all 191 patients with closed injuries recovered well. The average time to initial signs of recovery was 8 weeks (range, 1-27 weeks). Axonotmesis and Neurotmesis were found in 283 (89%) subjects. The average time to full recovery was determined to be 6 months (range, 1-22 months). The blast was found to be the main cause of nerve injury in 236 (74.2%) cases, followed by gunshot damage (21.4%, 68 subjects), falling from height and motor vehicle accidents (4.4%, 14 subjects) and multiple injuries (17%, 54 cases).
CONCLUSIONS: Trauma caused by factors such as explosions and gunshot worsens the condition of the injuries and presents the treatment conditions with many challenges. However, the success rate in post-surgical recovery of humerus fracture and injured radial nerve can be remarkably higher in young people as compared to other age groups.
