Paediatric open fractures presenting to a level 1 trauma centre: a 10 year epidemiological study.

PURPOSE: The epidemiology of paediatric fractures has been previously described, however there is limited data available on open fractures in this population. The purpose of this study was to investigate trends, mechanism of injury (MOI) and severity of paediatric open fractures and undertake an epidemiological study. METHODS: All children ≤ 16.0 years presenting with open fractures were identified between 01/04/2013 and 01/04/2023. Those with craniofacial, thoracic and distal phalangeal fractures were excluded. Incidence was calculated based on those presenting within the local geographical region. Social deprivation was measured using the Index of Multiple Deprivation (IMD). RESULTS: There were 208 open fractures with a median age of 11.0(q1 7.4-q3 13.4) years, and 153(74.6%) were in males. The MOIs were road traffic collisions 73(35.1%), sports/play 45(21.6%), fall > 2m 29(13.9%), simple fall 25(12.0%), crush 16(7.7%), bites 8(3.8%), assault 6(2.9%), and other 6(2.9%). Nineteen children (9.1%) presented with polytrauma. Gustilo-Anderson grade for long bone fractures were I-61(29.3%), II-24(11.5%), IIIa-36(17.3%), IIIb-30(14.4%) and IIIc-7(3.4%). There were 129 children presenting within the local geographical region providing an annual incidence of 8.0/100,000. Radius and ulna were the most frequently injured 49(38.0%) followed by tibia and fibula 44(34.1%). There were 69(53.5%) children presenting from an IMD quintile 1 with open fractures. CONCLUSION: Paediatric open fractures are commonly seen in the adolescent male and affect those who are from a more socially deprived background. These injuries account for 3.2% of fractures admitted to a MTC. Data suggests children principally sustain open fractures through two distinct injury patterns and ten-year trends suggests that there is a gradual decline in the annual incidence.

Resource implications of managing paediatric femoral fractures in a major trauma centre: Analysis of 98 cases.

INTRODUCTION: The management of paediatric femoral shaft fractures is expensive and is guided by age and fracture characteristics. The primary aim of this study was to perform a cost evaluation for managing paediatric femoral shaft fractures. The secondary aim of this study was to perform and compare costs of the different techniques of managing paediatric femoral shaft fractures. METHODS: Ninety-eight femoral shaft fractures in children aged ≤16 were identified between 01/06/2014-30/06/2019. Retrospective data of clinical complications were obtained on infection, malunion and non-union. Data on additional intervention, reoperations for complications and routine removal of metal work were obtained. Costing analysis was performed by a bottom-up calculation, and gathering Patient Level Information and Costing System (PLICS) data. RESULTS: There were 41 hip spica casting (HSC), 21 flexible intramedullary nailing (FIN), 14 submuscular plating (SMP), 19 rigid intramedullary nailing (RIN) and 3 external fixation (EF). Complications observed were HSC 3(7%); FIN 8(38%); SMP 2(14%); RIN 1(5%); EF 2(67%). The total costs for managing femoral shaft fractures were £8,955pp the costs for the different managements were; HSC £3,442pp; FIN £7,739pp; SMP £6,953pp; RIN £8,925pp; EF £19,116pp. The additional costs incurred for managing complications and routine removal of metal work for the internal fixation methods were: HSC 0.7%, FIN 23.7%, SMP 16.3%, RIN 10.9%, EF 28.1%. CONCLUSION: The operative management of paediatric femoral shaft fractures is associated with a high cost burden and this study demonstrates how financial data can be used to influence clinical management strategy. RIN carry a high initial implant cost however when considering the additional costs, such as treating complications it remains comparable to other modes of fixation. Our cost analysis did not demonstrate a significant difference between FIN, SMP and RIN. Due to the clinical complications observed and associated additional costs, we have discontinued the routine use of FIN for femoral shaft fractures at our centre. We recognise other centres may have a different complication and cost profile for each technique, but recommend they evaluate their practice given the potential economic benefit it has on the service provider.

Pelvic Tilt Changes After Hamstring Lengthening in Children With Cerebral Palsy.

BACKGROUND: Flexion deformity of the knee is a common presentation in children with cerebral palsy with hamstring surgery as an option for addressing this. However, concerns with regard to increased pelvic tilt have been raised. The purpose of this study was to compare preoperative and postoperative pelvic tilt after isolated hamstring lengthening versus combined hamstring lengthening and the influence of Gross Motor Function Classification System (GMFCS) levels on pelvic tilt. METHODS: This retrospective study included 46 ambulatory children with cerebral palsy who had had open medial hamstring lengthening (mean age at surgery, 11 y 11 mo; SD, 2 y 11 mo; GMFCS I, 16; GMFCS II 20; GMFCS III 10). Twelve children underwent isolated surgery and 34 children underwent combined surgery. The isolated hamstring procedures could be combined with foot and/or ankle-level surgery, as only the hamstring procedure would affect the pelvic tilt. Combined surgery was defined as hamstring lengthening with other procedures performed at the knee or more proximally. The preoperative and postoperative 3-dimensional gait analysis data were evaluated in this study. RESULTS: Both the isolated and combined hamstring lengthening groups showed no significant change in pelvic tilt ([INCREMENT]1.28, P=0.203; [INCREMENT]1.47, P=0.113, respectively). A significant change in pelvic tilt was seen in children functioning at GMFCS III ([INCREMENT]4.66, P=0.009) but not GMFCS I and II ([INCREMENT]0.37, P=0.718; [INCREMENT]0.48, P=0.697). Significant postoperative decreases in the knee flexion angle at initial contact were seen for both isolated ([INCREMENT]5.72, P=0.010) and combined hamstring lengthening ([INCREMENT]10.95, P<0.001). CONCLUSIONS: Hamstring lengthening, for the majority of patients, did not lead to a clinically significant change in mean pelvic tilt and improved knee flexion angle at initial contact. Children who functioned at GMFCS level III had an increase in anterior pelvic tilt and caution should be exercised in this group. STUDY DESIGN: Level IV evidence-case series.

Implant-related sepsis in lower limb fractures following gunshot injuries in the civilian population: A systematic review.

INTRODUCTION: The management of long bone lower limb fractures secondary to gunshot wounds (GSWs) in the civilian setting are complex and there is currently no consensus regarding the optimal approach to managing such fractures. This study aims to address the relationship of implant related sepsis in fractures secondary to GSWs. METHODS: A systematic review of the literature was performed on both Pubmed and Scopus databases that look at fractures caused by GSWs in the lower limb. A total of 14 studies met the inclusion criteria set in this study. RESULTS: Current literature suggests that low and high velocity injuries managed with internal fixation, such as intramedullary nails, may carry a low risk of superficial and deep infection, with no obvious risk of osteomyelitis. However, infection was poorly defined across all studies and no study used a validated scoring system for infection making it difficult to draw any valid conclusion on the rate of infection following internal fixation of lower limb fractures following both high and low velocity GSWs. CONCLUSION: There is no clear evidence to confirm or refute that internal fixation is the ideal method of management in these complex injuries and guidance is needed due to the high and increasing proportion of patients presenting with these complex injuries worldwide.

Fracture management in HIV positive individuals: a systematic review.

PURPOSE: Human immunodeficiency virus (HIV) infection could potentially play an important role in the management of fractures as they have been shown to affect fracture healing and the post-operative risk of implant sepsis. METHODS: A systematic review of the relevant literature was performed on PubMed and Scopus databases. Twenty-six studies were identified, critiqued and analysed accordingly. No randomised controlled trials were identified. RESULTS: HIV positivity was not shown to influence an individual's risk of early wound infection in operatively managed closed fractures. The rate of pin track infection in open injuries managed with external fixators was low. However, in open injuries managed with internal fixation, early wound infection rates were increased in the HIV-positive population compared to HIV-negative individuals. Regarding late implant infection, in closed fractures there appeared to be no increased risk of infection but there is limited evidence for open injuries. Additionally, further evidence is needed to establish if the rate of union in both open and closed fractures are influenced by HIV status. CONCLUSION: Overall, no evidence was found to suggest that surgical management of fractures in the HIV population should be avoided, and fixation of closed fractures in the HIV population appeared to be safe. The effect of anti-retroviral therapy is unclear and this should be further researched. However, based on the limited evidence, caution should be taken in the management of open fractures due to the potentially increased infection risk. The impact of anti-retroviral therapy on the outcomes of surgery needs further evaluation.
