Forearm fractures are a common paediatric injury. This study was aimed to describe the epidemiological of paediatric forearm fractures in the urban population of Glasgow.

We reviewed of all the forearm fracture treated by the orthopaedic service in Yorkhill Children's Hospital in 2008. Datum gathered from case notes and radiographs using the prospective orthopaedic database to identify patients with forearm fractures. The age, sex, side and type of fracture, the timing and mechanism of the injury and treatment were documented for the 436 fractures. Census data were used to derive absolute age-specific incidences.

Distinction was made between torus and other types of fractures. Torus fractures require no specific orthopaedic treatment and were segregated out. For the remaining 314 fractures, the age and sex distribution, seasonal variation of fractures and treatments for each type of fracture were examined. The incidence of forearm fractures in our population is 411 fractures per 100,000 population per year. An increased number of fractures occurred during the months of May and August. A fall from less than one metre was the commonest mechanism of injury, sporting injuries were the second commonest with football the most common sport associated.

This study identifies some features which are in good agreement with studies from elsewhere in Britain, such as incidence and seasonality. However, there are also interesting differences – such as the Glasgow peak incidence for forearm fractures being at age 8, with a marked decline by 12 years. Furthermore, our findings have been extended to consideration of type of intervention, and likelihood of successful treatment.

Pelvic fractures in children are uncommon. Despite their potentially serious nature, there is little information in the literature regarding their epidemiology.

We performed a retrospective review of case notes and radiographs, if available, of all patients admitted with bony pelvic injuries to our unit over a 28 year period (1980-2008). Sixty-four children with pelvic fractures were identified (median age 8 years, 75% male). 58% were pedestrians involved in road traffic accidents (RTA), 19% were caused by a fall from a height and 8% were crush injuries. There was seasonal variability, with a 50% increase in pelvic injuries in Autumn and 33% decrease in Winter - compared to Spring/Summer months (in contrast to the peak in overall fracture incidence in the Summer). Median length of stay was 8 days (range 1-180), 11% requiring direct admission to ITU and 5% to HDU. There is a high incidence of associated major injuries - for Stable fractures 52%, Partially stable fractures 60% and Unstable fractures 100%. Five required surgery to the bony pelvis, and 6 for-non pelvic orthopaedic injury. 3 required operative intervention from other specialities, 1 urological repair, 1 laparotomy and 1 lobectomy.

Pelvic fractures in children are potentially serious injuries with a high proportion of major associated injuries. Multiple injuries were sustained in 55% of pedestrian/RTA accidents, 100% of crush injuries and 58% of falls from a height. In this series, 52% of “Stable” pelvic injuries were associated with other major injuries. All paediatric pelvic injuries, even stable pubic rami fractures should be approached with caution, full ATLS assessment and close monitoring.

Supracondylar fractures of the humerus (SCFH) are the most common type of paediatric elbow fractures. Due to beliefs that non-operatively managed SCFH may displace further from the original position, they are monitored with repeated radiographs and a large number are unnecessarily surgically pinned. Very limited evidence currently exists to support these beliefs. This study aimed to determine the incidence of late “significant” displacement (requiring surgical management) of non-operatively managed paediatric SCFH, and whether they necessitate close radiographic follow-up. Patients aged ≤16, with a SCFH, were included in this retrospective cohort study. All were initially managed non-operatively with at least one follow-up radiograph within six weeks of injury. Data from four consecutive years (2013–2016) was collected using the hospital's radiology database. Two observers independently analysed patient radiographs and classified fractures by the Gartland and AO systems. The incidence of late displacement was determined using follow-up radiographs and clinic notes. Of the 164 patients included in the study, one patient (Gartland Type II, AO Type III) suffered late displacement at two weeks, requiring surgical fixation. One further patient (AO Type II) had a persistent cubitus varus deformity (Baumann's angle 90°), with no long-term functional deficit. Incidence of late displacement was 0.6% (n=1). Our findings suggest that stable Gartland Type I/AO Type I and II fractures do not require repeated radiographic follow-up. However, some Gartland Type II/AO Type III fractures require monitoring. This could considerably reduce the financial costs for the healthcare system, and inconvenience to families, associated with repeated follow-ups.

Introduction

Two randomised trials concluded cast type (above or below elbow) makes no significant difference in the re-displacement rate of paediatric forearm fractures involving the distal third of the radius. This has not, however, led to the universal use of below elbow casts. In particular we noted one trial reported significant re-displacement in 40% or more of cases, which was much higher than we would expect.

To review the radiological outcomes and need for re-manipulation of paediatric distal forearm fractures treated with closed manipulation under anaesthesia in our institution, in part for subsequent comparison with published results.

All forearm fractures treated at a specialist children's hospital in one year were reviewed retrospectively. Based on the methodology of one trial, we included all fractures involving the distal third of the radius, with or without an ulna fracture, which underwent closed manipulation. Outcomes were radiological alignment using existing radiographs and need for re-manipulation. Cast type was at the discretion of the treating surgeon. The radiological criteria for re-displacement were based on published methodology.

79 children underwent manipulation, 71 receiving above elbow casts and 8 below elbow casts. Radiologically 21% of injuries treated in an above elbow cast re-displaced (15/71) compared to 38% of those in below elbow plasters (3/8). In 2 cases the re-displacement was treated with re-manipulation.

The preference in our institution was clearly for above elbow casts in this injury pattern. The small number of below elbow casts in our series limits any comparisons. Our rate of re-displacement using above elbow casts was half that of one of the published studies, so the existing literature is not consistent with our experience.
