Aims. Compartment syndrome (CS) is a well-recognised, serious complication of long bone fractures. The association between CS and tibial shaft fractures is well documented in adult patients and in children with open or high velocity trauma. There is, however, little literature on the risk of developing CS in children with closed tibial fractures. In a number of units these children are routinely admitted for elevation and monitoring for CS. We audited our experience of managing paediatric tibial fractures to ascertain whether it may be safe to discharge a sub-group of these children. Methods. We audited all children up to the age of 12 years admitted to our hospital over a 5 year period. We reviewed radiographs and clinical notes to determine fracture pattern, modality of treatment, and complications. Results. We audited 159 tibial fractures. The mean age was 5.8 years (1–12 years), 95 boys, 64 girls. 105 (66%) closed fractures were conservatively managed: 87 of these were diaphyseal and 20 involved both tibia and fibula. Of the conservatively managed fractures, 89 (85%) were minimally displaced (< 5 degrees varus/valgus/anterior angulation, < 5 degrees rotation, < 5mm shortening, no posterior angulation). In the conservatively managed group there were 3 cases of angulation in cast, managed with wedging. There were no other complications and no cases of compartment syndrome. Conclusion. Of the 105 closed tibial fractures we managed conservatively, most were minimally displaced, diaphyseal, tibia-only fractures. No patient developed compartment syndrome. Based on our experience we suggest that children with closed, minimally displaced tibial fractures do not require admission for monitoring of CS and may go home in a plaster-slab with early fracture clinic follow-up providing suitable supervision is in place, pain is controlled, and they are able to mobilise safely

To analyse the management of open paediatric tibial fractures treated at a children's Major Trauma Centre (MTC), comparing fixation methods, union and complications. We retrospectively identified all patients admitted to RMCH with an open tibia fracture between 2008 – 2016. Demographics, mechanism, inpatient stay and follow-up management were reviewed. There were a total of 44 patients, with an average age = 10 years (3–15). 93% of cases were caused by road traffic accidents, commonly pedestrian versus car. Older children were more likely to sustain higher grade injuries, requiring increased length of stay. 35 patients had primary / delayed wound closure, 1 patient required fasciotomies and 4/44 needed skin grafts and/or flap. 7 patients were treated in plaster, 9 by elastic nailing, 15 had mono-lateral fixators and 12 with circular frame. The average number of surgeries = 3 (1–7) with older children having increased risk of revision surgery. Monolateral fixators were the most common primary fixation method (n=15), however 60% required revision to ring fixator due to displacement or delayed union. The main risk factor for displacement was inadequate fracture reduction in theatre, as well as those fracture patterns involving butterfly fragments. Union (defined as RUST score = 3 on >3 cortices) was achieved in all patients (ave 6 months). Delayed union was associated with higher grade injuries, those treated with elastic nails demonstrated the longest union time (ave 7.3 months). 21/44 (47.7%) patients had complications, with pin site infection being the most commonly seen. 18% patients suffered a major complications needing further surgery. Various fixation methods can be successfully used to treat these fractures. They demonstrate a high complication rate and often require multiple surgeries, with union taking an average of 6 months. Mono-lateral fixators demonstrate a high revision rate, particularly if the fracture is not well reduced

Introduction: Paediatric tibial fractures, unlike femoral fractures do not have much potential for overgrowth. In simple factures of the tibial shaft treated non-operatively the major problems are shortening and malunion. In complex injuries with extensive soft tissue disruption and bone loss, the long-term aim of reconstruction is to achieve union with a fully functional limb without limb-length inequality. Methods: Four children who sustained high-energy grade III open fractures of the tibia were treated with acute shortening and bone transport. Any soft tissue reconstructive and secondary grafting procedures for delayed union were recorded. The children were prospectively followed up to fracture union. Distraction ostegenesis proceeded until limb length equality was achieved and the regenerate allowed to consolidate. Discussion: Despite achieving equal limb lengths at the end of distraction osteogenesis the injured tibia overgrew by 1–2cm at three years post injury. This would suggest that even in the presence of extensive soft tissue trauma, as seen in these high energy injuries, the increased blood flow associated with metaphyseal corticotomy stimulates epiphyseal activity resulting in overgrowth. The value of stopping adjustments just short of achieving limb length equality to allow for expected overgrowth in the injured tibia merits further investigation

Introduction. Paediatric tibial fractures, unlike femoral fractures do not have much potential for overgrowth. In simple factures of the tibial shaft treated non-operatively the major problems are shortening and malunion. In complex injuries with extensive soft tissue disruption and bone loss, the long-term aim of reconstruction is to achieve union with a fully functional limb without limb-length inequality. Methods. Four children (Age range 6-12 years) who sustained high-energy grade III open fractures of the tibia were treated with acute shortening and bone transport. Any soft tissue reconstructive and secondary grafting procedures for delayed union were recorded. The children were prospectively followed up to fracture union. Distraction ostegenesis proceeded until limb length equality was achieved and the regenerate allowed to consolidate. Results. Three children had grade 3B injuries, 2 requiring flap reconstruction. One had a grade 3A injury. Mean acute shortening was 4.4cm (Range 2-9cm). Distraction osteogenesis was used to achieve limb-length equalisation. 2 children required secondary bone graft procedures to achieve union. At 3 years from injury, all children had overgrowth of the injured leg averaging 2cm. Discussion. Despite achieving equal limb lengths at the end of distraction osteogenesis the injured tibia overgrew by a mean of 2cm at three years post injury. This would suggest that even in the presence of extensive soft tissue trauma, as seen in these high energy injuries, the increased blood flow associated with metaphyseal corticotomy stimulates epiphyseal activity resulting in overgrowth. The value of stopping adjustments just short of achieving limb length equality to allow for expected overgrowth in the injured tibia merits further investigation

Purpose. Pediatric tibial shaft fractures (TSF) account for 15% of long bone fractures in children. Compartment syndrome (CS) is difficult to diagnose in children, often leading to disastrous outcomes. This study investigated the incidence of CS in TSF and its associated risk factors. Method. A detailed five-year retrospective chart review of TSF treated at a major pediatric hospital. CS was diagnosed clinically or by intra-compartment pressure. Multivariate logistic regression analysis tested age, gender, mechanism of injury, time to surgery, fracture type, and treatment intervention as possible risk factors for CS. Results. There were 216 TSF in 212 children (160 males, 52 females; mean age 13.6 years, range eight-18 years). One hundred and thirty-two (61%) fractures were treated with closed reduction and casting, 36 with external fixation, 21 with flexible intramedullary nails, and 27 with locked intramedullary nails. There were 23 cases of CS (10.6%). Multivariate predictors of CS included age 14 years and older (21/96 = 22%, p < 0.001) and motor vehicle accident (MVA) (12/57 = 21%, p = 0.002). Incidence of CS was 44% among patients 14 and older who sustained MVA (11 of 25). Gender, AO fracture type, time to surgery and surgical fixation were not predictive of CS. Conclusion. This is the first large study to report the incidence of CS from TSF in children. The incidence of 10.6% is higher than previously reported and much higher in patients 14 years of age and older and involved in an MVA. Surgeons should be especially aware and suspicious of CS in children with tibial shaft fractures who have these risk factors
