Insights
Paediatric upper extremity fractures decreased overall in Germany, but clavicle and forearm fracture treatments increased significantly between 2002 and 2017. This suggests a shift towards more operative interventions for these common childhood injuries.
Area of Science:
- Orthopaedics
- Paediatric Trauma
- Epidemiology
Background:
- Limited recent data exists on paediatric fracture frequencies in Germany.
- Understanding trends in paediatric upper extremity fractures is crucial for healthcare planning.
Purpose of the Study:
- To analyze the frequency of common paediatric upper extremity fractures in German hospitals in 2002 and 2017.
- To identify temporal changes in fracture incidence and patterns over time.
Main Methods:
- Utilized inpatient data from the German National Hospital Discharge Registry.
- Analyzed absolute frequencies and incidences of nine specific upper extremity fracture locations across four age groups (0-19 years).
- Calculated boy-girl ratios (BGR) and incidence rate ratios (IRRs) to compare 2002 and 2017 data.
Main Results:
- Total paediatric upper extremity fractures decreased from 38,480 (2002) to 35,128 (2017).
- Clavicle fracture incidence increased (IRR ≥ 1.72), while humerus fractures remained stable or decreased (IRR ≤ 1.00).
- Forearm fractures showed increased incidence in younger children (IRR ≥ 1.44) and a trend towards operative treatment.
Conclusions:
- Despite an overall decrease in numbers, in-hospital treatment for paediatric clavicle and forearm fractures rose significantly.
- These findings indicate a potential shift towards more operative management for specific paediatric fractures in Germany.
Introduction:
Recent studies investigating the frequency of paediatric fractures in Germany are not available. The primary aim of this study was to report frequencies of the most common paediatric upper extremity fractures treated in German hospitals in 2002 and 2017 and to detect changes over time.
Methods:
This study used inpatient data from the German National Hospital Discharge Registry. Absolute frequencies and incidences of the following fracture localisations were analysed: clavicle, proximal humerus, humerus shaft, distal humerus, ulna shaft, radius shaft, forearm shaft, distal radius, and distal forearm. Four age groups were formed: 0-4, 5-9, 10-14, and 15-19 years. The boy-girl ratio (BGR) was calculated for all fracture localisations for both years, respectively. Incidence rate ratios (IRRs) were calculated to compare fracture incidences between 2002 and 2017.
Results:
The absolute number of the nine fracture localisations together decreased from 38,480 in 2002 to 35,128 in 2017. The overall BGR was 2.0 in both years. The BGR increased with increasing patient age. The incidence of clavicle fractures increased from 2002 to 2017 (IRR ≥ 1.72), while that of humerus fractures (proximal, shaft, and distal) remained the same or decreased (IRR ≤ 1.00) within all age groups. The incidence of isolated ulna or radius shaft fractures increased slightly or remained the same in the two lower age groups (IRR ≥ 1.00), while it decreased in the two higher age groups (IRR ≤ 0.80). Furthermore, complete forearm fractures were more frequent in the 0-4, 5-9, and 10-14 year age groups (IRR ≥ 1.44) in 2017 compared to 2002. The incidence of distal radius und forearm fractures changed only slightly.
Conclusions:
The absolute number of paediatric upper extremity fractures decreased from 2002 to 2017, while the incidence of in-hospital treatment of clavicle and forearm fractures increased significantly, indicating a trend towards operative treatment.
