Incidence, characteristics, and treatments of traumatic open fractures in children and adolescents: A retrospective observational study

Abstract

We aimed to investigate the incidence, characteristics, and treatments of open fractures in children and adolescents (≤18 years old). We retrospectively reviewed the records of 2418 children and adolescents who presented with traumatic fractures and were admitted to our university-affiliated hospitals, among which 206 patients (8.5%) presented with open fractures. The patients' clinical and radiographic records were reviewed, and the age, gender, cause of injury, injury season, injury week, associated injuries and complications were collected. This study enrolled 1789 males (74.0%) and 629 females (26.0%) with an average age of 11.2 ± 5.0 years. The patients were divided into an open fracture group (OF group, n = 206) and a group with no open fracture (No-OF group, n = 2212). There were 206 patients (8.5%) who presented with open fractures and the most common fracture sites were the tibia (31.1%, 64/206) and fibula (20.9%, 43/206). The patients in the OF group presented with higher frequency of emergency admission (P < 0.001), self-supporting medical insurance (P < 0.001), MVCs (P < 0.001), wounded by machine (P < 0.001), struck by object (P < 0.001), hurt/cut by others (P < 0.001), lower limb fractures (P < 0.001), multiple fractures (P = 0.010), associated injuries (P < 0.001) and wound infection (P = 0.003) then the patients in the No-OF group. The most common complication were wound infection (5.8%) and pneumonia (1.0%) in the OF group, wound infection (2.1%) and pressure sores (2.0%) in the No- OF group. Multivariate logistic regression analysis indicated that mechanical trauma (OR = 64.229, P < 0.001), being hurt/cut by others (OR = 26.757, P < 0.001), and being struck by an object (OR = 15.345, P < 0.001) were stronger risk factors for open fracture than were low falls; additionally, lower limb fractures (OR = 5.970, P < 0.001), upper limb fractures (OR = 5.865, P < 0.001) and multiple fractures (OR = 5.414, P < 0.001) were stronger risk factors than craniofacial fractures for open fractures. The frequency of surgical treatment for the patients with traumatic open fractures (87.9%, 181/206) was significantly higher than those without open fractures (72.2%, 1596/2212) (P < 0.001). The hospital stays and fees for surgical treatment for the patients with traumatic open fractures were significantly higher than those without open fractures (P < 0.001). Etiology (especially being injured by a machine or being hurt/cut by others) and the fracture site (including lower limb fractures and upper limb fractures) were independent risk factors for open fractures. Traumatic open fractures presented with higher surgical treatment rate, hospital stays and fees.
