AbstractBackground and objectives: In the paediatric population, hand injuries are one of the most frequent injuries and the second most frequent area of fracture. It is estimated that hand injuries account for up to 23% of the trauma-related causes of emergency department visits. Not only are they a significant factor in health care costs, but they may also lead to detrimental and long-term consequences for the patient. The discrepancy observed between the published studies suggests a geographical variation in their epidemiology. The aim of this study is to determine the localisation of injuries and fractures involving the hand in the paediatric population of the Polish Silesia region. This exploratory cross-sectional study involved 1441 post-traumatic hand X-ray examinations performed at the Department of Diagnostic Imaging of the John Paul II Upper Silesian Child Health Centre in Katowice between January and December 2014. Materials and Methods: The study group consisted of 656 girls and 785 boys who were 11.65 ± 3.50 and 11.51 ± 3.98 years old, respectively (range: 1-18 years). All examinations were evaluated for the location of the injury and presence of fracture(s). Results: Finger injuries were dominant (n = 1346), with the fifth finger being the most frequently injured (n = 381). The majority of injuries were observed among children who were 11 years old (n = 176), with a visible peak in the 11- to 13-year-old group. A total of 625 bone fractures were detected. Fractures of the proximal phalanges (n = 213) and middle phalanges (n = 159) were most common, and fifth finger (n = 189) predominance was again observed. A gender-independent positive correlation was found between patients' age and finger injuries (p < 0.01) as well as metacarpal injuries (p < 0.01). There was no correlation between patients' age and fractures in these locations (p > 0.05). Metacarpal injuries (p < 0.01), finger injuries (p < 0.01), fractures (p = 0.01), and fractures with displacement (p = 0.03) were more common among males regardless of age. Conclusions: The results indicate that 11-year-old boys are at an increased risk of hand injuries and fractures. The distal and middle phalanges of the right hand, especially of the fifth digit, were the most susceptible to fracture localisation. Thus, injuries in these areas should be perceived as most likely to cause fractures and therefore demand careful examination.
