In response to the COVID-19 pandemic public health measures were implemented to limit virus spread. After initial implementation of a province-wide lockdown (Stage 1), there followed a sequential ease of restrictions through Stages 2 and 3 over a 6-month period from March to September 2020 (Table 1). We aimed to determine the impact of COVID-19 public health measures on the epidemiology of operative paediatric orthopaedic trauma and to determine differential effects of each stage of lockdown. A retrospective cohort study was performed comparing all emergency department (ED) visits for musculoskeletal trauma and operatively treated orthopaedic trauma cases at a Level-1 paediatric trauma center during Mar-Sep 2020 (pandemic), compared with Mar-Sep 2019 (pre-pandemic). All operative cases were analyzed based on injury severity, mechanism of injury (MOI) and anatomic location (AL). Comparisons between groups were assessed using chi-square testing for categorical variables, and student t-tests and Fisher's exact tests for continuous variables. During the pandemic period, ED visits for orthopaedic trauma decreased compared to pre-pandemic levels by 23% (1370 vs 1790 patients) and operative treatment decreased by 28% (283 vs 391 patients). There was a significant decrease in the number of operative cases per day in lockdown Stage 1 (1.25 pandemic vs 1.90 pre- pandemic; p < 0 .001) and Stage 2 (1.65 pandemic vs 3.03 pre-pandemic; p< 0.001) but no difference in operative case number during Stage 3 (2.18 pandemic vs 2.45 pre-pandemic; p=0.35). Significant differences were found in MOI and AL during Stage 1 (p < 0 .001) and Stage 2 (p < 0 .001) compared to pre-pandemic. During Stage 1 and 2, playground injuries decreased by 95% and 82%, respectively; sports injuries decreased by 79% and 13%, and trampoline injuries decreased 44% and 43%, compared to pre-pandemic. However, self-propelled transit injuries (bicycles/skateboards) increased during Stage 1 and Stage 2 by 67% and 28%, respectively compared to pre- pandemic. During lockdown Stage 3 there were no differences in MOI nor AL. There were no significant differences in injury severity in any lockdown stage compared to pre-pandemic. COVID-19 lockdown measures significantly reduced the burden of operative paediatric orthopaedic trauma. Differences in volume, mechanism and pattern of injuries varied by lockdown stage offering evidence of the burden of operative trauma related to specific childhood activities. These findings will assist health systems planning for future pandemics and suggest that improvements in safety of playgrounds and self-propelled transit are important in reducing severe childhood injury requiring operative intervention.

Applying the concept of a regional trauma network to the UK paediatric trauma population has unique difficulties in terms of low patient volume and variation in paediatric service provision. In addition, no consensus exists as to which radiological investigations should be employed and an increasing trend towards computerised tomography raises concerns over radiation exposure. We carried out a retrospective review of all paediatric trauma calls from April 2010 and March 2013 around becoming a Major Trauma Centre. We aim to analyse the impact this has on trauma calls and assess the radiological investigations currently used in this population. The number of yearly paediatric trauma calls doubled during our study and totalled 132. The commonest mechanisms of injury were road traffic collisions, fall from a height or fall off a horse. 91.7% of children had some form of radiological investigation; 67% plain radiograph, 37.1% trauma CT, 21.2% focused CT and 5.3% abdominal ultrasound scan. Of the 77 CT scans performed 57.1% were reported as normal and 54.5% of these patients were discharged home the same day. Five children re-attended the emergency department within 30 days with two positive findings; a subdural haematoma and a tibial plateau fracture. The current use of harmful radiological investigations in paediatric trauma patients is not uniform. We propose implementation of radiology protocols and clinical guidance to imaging in paediatric trauma to limited radiation exposure

Introduction. In response to the COVID-19 pandemic, there was a rapidly implemented restructuring of UK healthcare services. The The Royal National Orthopaedic Hospital, Stanmore, became a central hub for the provision of trauma services for North Central/East London (NCEL) while providing a musculoskeletal tumour service for the south of England, the Midlands, and Wales and an urgent spinal service for London. This study reviews our paediatric practice over this period in order to share our experience and lessons learned. Our hospital admission pathways are described and the safety of surgical and interventional radiological procedures performed under general anaesthesia (GA) with regards to COVID-19 in a paediatric population are evaluated. Methods. All paediatric patients (≤ 16 years) treated in our institution during the six-week peak period of the pandemic were included. Prospective data for all paediatric trauma and urgent elective admissions and retrospective data for all sarcoma admissions were collected. Telephone interviews were conducted with all patients and families to assess COVID-19 related morbidity at 14 days post-discharge. Results. Overall, 100 children underwent surgery or interventional radiological procedures under GA between 20 March and 8 May 2020. There were 35 trauma cases, 20 urgent elective orthopaedic cases, two spinal emergency cases, 25 admissions for interventional radiology procedures, and 18 tumour cases. 78% of trauma cases were performed within 24 hours of referral. In the 97% who responded at two weeks following discharge, there were no cases of symptomatic COVID-19 in any patient or member of their households. Conclusion. Despite the extensive restructuring of services and the widespread concerns over the surgical and anaesthetic management of paediatric patients during this period, we treated 100 asymptomatic patients across different orthopaedic subspecialties without apparent COVID-19 or unexpected respiratory complications in the early postoperative period. The data provides assurance for health care professionals and families and informs the consenting process. Cite this article: Bone Joint Open 2020;1-6:287–292

At-home softcast removal with no routine clinical follow-up has shown to be safe and effective following paediatric orthopaedic trauma. It minimises clinician contact time and reduces cost. However, there is limited data on the caregiver experience. Retrospective analysis of paediatric fractures requiring application of circumferential softcast that was later removed at home. Two time points were included: (1)July–September 2022, (2)February–April 2023. Demographics data included age, fracture classification, angulation, manipulation requirement, complications or unplanned re-attendance. Caregivers were given an information leaflet on cast removal. Caregivers completed a telephone Likert questionnaire reviewing time taken to remove cast, qualitative descriptors of cast removal and overall satisfaction. 77 families were contacted at mean 93 days post injury. Mean age was 7.5 years. 41(53%) were distal radius and 20(26%) both-bone forearm fractures. The remaining were hand, elbow or tibia injuries. 40(52%) injuries required manipulation under procedural sedation with mean sagittal angulation 24 degrees. 13(17%) patients re-attended with cast problems. Caregivers estimated a mean 13 minutes to remove cast. 83% found it ‘extremely’ or ‘somewhat’ easy. 75% were ‘extremely’ or ‘somewhat’ satisfied. 71% were ‘extremely’ or ‘somewhat’ likely to recommend at-home cast removal. Qualitative descriptors ranged from from ‘traumatising’ to ‘fun’ and ‘straightforward’. The experience at our tertiary centre confirms at-home softcast removal with no further orthopaedic follow-up is safe and feasible, even in those requiring manipulation under sedation. The majority of families reported a positive experience; this however is not universal. Adequate patient information resources are integral to a positive caregiver's experiences

Purpose. A review of the role of external fixators in paediatric trauma at The Royal London Hospital Trauma and Orthopaedic Department. Methods. Retrospective study between 2004 and 2010 reviewing traumatic bone injuries that required initial management with an external fixator. Information was collected through the patients' medical documents and radiographs. Results. In total twenty-seven patients (15 male:12 female, mean age 11, age range 7-15) were initially treated with external fixators over the six year period. The injured bones included 18 tibias, 5 femurs, 2 humeri, 2 radius/ulna, 2 phalanges and 1 wrist. Three patients had two fractures requiring external fixators. Four patients had associated head injuries. Indications included twenty –one open fractures (3 Gustilo type 2, 6 Gustilo type 3A, 12 Gustilo type 3B), seven closed fractures in poly-trauma patients and two closed severely comminuted fractures. Ten fractures were treated with the external fixator as the definitive treatment, fourteen had application of cast following removal of the external fixator and six were converted to internal fixation. Twenty-eight Linear frames were applied (23 Hoffman IIs, 5 Compact Hoffmans) and two circular frames. Mean duration of frame stabilisation was 8 weeks (range 1-16 weeks). Complications included 2 pin site infections successfully treated with antibiotics, 2 patients with hypertrophic scars, 2 leg length discrepancies secondary to bone loss, 2 patients had delayed union and 2 patients had a lower limb deformity requiring intervention, one for adjustment of frame and the other for correction osteotomy with circular frame. Conclusion. The use of external fixators has an important role to play in the management of open fractures and poly-trauma paediatric patients

Purpose:. Non-contiguous spinal injury can add significant complexity to the diagnosis, management and outcome in children. There is very little in the paediatric literature examining the nature, associated risk factors, management and outcomes of non-contiguous spinal injuries. The objective is to determine the incidence and clinical characteristics of non-contiguous spinal injuries in a paediatric population. The secondary objective is to identify high risk patients requiring further imaging to rule out non-contiguous spinal injuries. Methods:. All children up to 18 years of age with a spinal injury, as defined by ICD-09 codes at one paediatric trauma hospital were included (n=211). Data for patient demographics, mechanism of injury, spinal levels involved, extent of neurologic injury and recovery, associated injuries, medical complications, treatment and outcome were recorded. Results:. Twenty five (11.8%) out of 211 patients had non-contiguous spinal injuries. The mean age was 10.7 years. The most common pattern of injury was a double thoracic non-contiguous injury. 16% of cases of NCSI were initially missed, but with no clinical deterioration due to the missed diagnosis. Associated injuries occurred in 52% of patients with NCSI. Twenty-four percent of patients with multiple non-contiguous spinal injuries had a neurologic injury compared to 9.7% in patients with single level or contiguous injuries (p=0.046). Conclusions:. There is a high incidence of children with multiple non-contiguous spinal injuries who are more likely to suffer neurological injuries compared to patients with single level or contiguous spinal injuries. Patients with a single level spinal injury on existing imaging and a neurological injury should have entire spine lateral radiographs to exclude non-contiguous injuries. In patients without neurologic injury and a single spinal fracture, radiographs showing at least 7 levels above and below the fracture should be performed. All children with spinal injury should have associated injuries carefully excluded

Purpose

To examine the management and outcome of patients suffering complex paediatric lower limb injuries with bone and soft tissue loss.

Aim: Controversy remains regarding the complications/necessity for removal of metalwork used in the fixation of paediatric orthopaedic surgery owing to potential complications of removal. It was the aim of this study to review all cases of metalwork removal performed in a prescribed year in order to ascertain the reasons for removal and complications of these surgeries.

Methods: All cases of metalwork removal performed under GA, from 1st January 2006 until 31st December 2006 in a regional paediatric orthopaedic unit, were reviewed. Data were obtained from case notes, computer and theatre records and radiographs. Details were obtained regarding demographic details, anatomic site, implant used, reasons for removal, problems of initial fixation and complications after removal.

Results: 34 buried kirschner wires were removed under general anaesthetic. Of other metal work, 38 implants were removed; 22 in males and 16 in females. The commonest age distribution was the 11–15 age groups. The most common anatomic site for removal was the forearm (42%) followed by the femur (18%) and ankle (18%). The most common implant removed was plate (53%), followed by Nancy nails (18%). Problems following initial insertion were found in 4 patients (10.5%) including re-fracture distal to forearm plates (both in patients with co-existing osteopaenia), bowing of forearm and decreased sensation over the thumb. Metal work was removed for symptoms in 13 cases (34%) and the rest for patient request or clinical indications. Complications after metalwork removal occurred in 8 (21%) patients and included re-fracture of forearm (2), hypertrophic scar, abscess, skin reaction, wound breakdown, excessive bruising and discomfort.

Conclusion: As routine removal of metalwork is generally considered not necessary, metalwork removal is often carried out for symptoms, at patient request as well as in patients with osteopaenia who have risk of fracture at the ends of metalwork. Parents need to be made aware of possible complications shown in the study, in order to give informed consent.

Introduction: Children are inevitably casualties in wars. They are treated variously by local doctors and foreign surgeons working for military and Non-Governmental Organisations. The basic principles of surgical treatment of war wounds are the same as for adults, but there are specific differences in injury pattern and the response to injury that must be borne in mind. Method: Casualties under sixteen years age with extremity trauma caused by missiles or blast admitted to a British military field hospital during the latest Gulf War were evaluated. The date, time and method of wounding were recorded and ICRC Wound Scores calculated. The details of surgical treatment prior to admission, and further surgical management described. Case studies were used to illustrate particular considerations relevant to paediatric trauma. Results: The records for sixteen wounded children were available for analysis. Their ages ranged from three to fifteen years. The method of injury falls into three phases, gun-shot wounds during the mobile attack, shell fragment wounds during the seige of urban areas and blast/fragment injuries from small munitions from the period following active fighting. Blast/fragment wounds typically affected multiple body areas. Half the patients had received surgical treatment before reaching the hospital, either at civilian hospitals, forward military surgical units or both. None of this surgery was strictly “life or limb-saving”. Amputations performed prior to admission were in the proximal tibia and followed the long posterior flap pattern appropriate to an adult amputation for vascular disease regardless of the level of injury. Several had primary closure of war wounds. After admission, four patients required plastic surgical procedures, two had ophthalmic surgery, one had a laparotomy and one had a facial reconstruction procedure in addition to surgery for extremity trauma. One child with fragment wounds was undergoing treatment for acute lymphoblastic leukaemia. Conclusion: A military hospital must be prepared to treat children during war-time. Multi-system injury patterns are common and require multidisciplinary care. When possible children should be transferred to a facility with specialist care available for primary surgery. The effects of injury and treatment on future growth should be given more consideration

Aims: There are no large published studies examining the complication rates associated with use of Kirschner wires in þxation of a wide variety of paediatric fractures. The aim of this study is to analyse the outcomes of fracture þxation using K-wire in upper limb fractures in children and to critically assess the incidence and type of complications. Methods: This study is a retrospective review of a consecutive series of 107 fractures in 105 paediatric trauma cases treated with K-wire in between 01.09.99 to 10.09.01. Results: The fractures were fractures around Wrist (47%) and around elbow (45%). 66 (61.68%) were performed by closed percutaneous technique, 27 (25.23%) by open method and in 14 (13.08%) combined approach was used. Around there were 13 cases with over-granulation at wound site, 6 cases of Soft tissue infection, 2 cases with tendinitis, 1 case of Osteo-myelitis and 1 case with hyper-sensitive scar. 3 cases found to have postoperative neurapraxia and 1 case with axonotmesis. Metal migration was detected in 4 cases and 14 cases found to have shown wire loosening. 10 fractures have lost position in postoperative period out of which 2 cases were reoperated for Re K-wire, 1 had undergone Re-MUA and 7 left for remodelling. Conclusions: K-wires are versatile but are not inherently benign. We conclude that best results could be achieved if total life of K-wire can be restricted to 3–4 weeks. We recommend one should explain all these risks and complications during consenting for K-wiring procedures

Purpose of Study. We report the outcome of five cases of chronic paediatric Monteggia lesion treated with a modified Bell-Tawse procedure. Methods. Five patients with a chronic Monteggia lesion were treated over an eight-year period (2004–2012) at our institution. All underwent a modified Bell-Tawse procedure. The patient medical records were retrospectively analysed. We report the outcome in five patients. Results. Four girls and one boy were treated for a chronic Monteggia lesion in the period studied. The mean age at time of surgery was 8 years old (range 4–14 years). The mechanism of injury was post-traumatic in four of the five cases, while in one case the mechanism was uncertain. All children underwent modified Bell-Tawse procedure. All children ultimately required ulnar osteotomy, while two also required radial osteotomy. At a mean follow-up of 22 months (range 16–38 months), four children had experienced complications. Symptomatic metalwork was removed in one case, two children re-dislocated the affected joint, and one child required revision Bell-Tawse procedure. No nerve palsies were noted on follow-up. Conclusion. Paediatric elbow trauma necessitates early, senior management. We report a series of five patients who underwent modified Bell-Tawse procedure for chronic Monteggia lesion. Four of the five children experienced complications. All required shortening osteotomies. The chronic Monteggia lesion is an unusual but troublesome presentation in the paediatric population. Further research in the area is necessary

Aims. The current global pandemic due to COVID-19 is generating significant burden on the health service in the UK. On 23 March 2020, the UK government issued requirements for a national lockdown. The aim of this multicentre study is to gain a greater understanding of the impact lockdown has had on the rates, mechanisms and types of injuries together with their management across a regional trauma service. Methods. Data was collected from an adult major trauma centre, paediatric major trauma centre, district general hospital, and a regional hand trauma unit. Data collection included patient demographics, injury mechanism, injury type and treatment required. Time periods studied corresponded with the two weeks leading up to lockdown in the UK, two weeks during lockdown, and the same two-week period in 2019. Results. There was a 55.7% (12,935 vs 5,733) reduction in total accident and emergency (A&E) attendances with a 53.7% (354 vs 164) reduction in trauma admissions during lockdown compared to 2019. The number of patients with fragility fractures requiring admission remained constant (32 patients in 2019 vs 31 patients during lockdown; p > 0.05). Road traffic collisions (57.1%, n = 8) were the commonest cause of major trauma admissions during lockdown. There was a significant increase in DIY related-hand injuries (26% (n = 13)) lockdown vs 8% (n = 11 in 2019, p = 0.006) during lockdown, which resulted in an increase in nerve injuries (12% (n = 6 in lockdown) vs 2.5% (n = 3 in 2019, p = 0.015) and hand infections (24% (n = 12) in lockdown vs 6.2% (n = 8) in 2019, p = 0.002). Conclusion. The national lockdown has dramatically reduced orthopaedic trauma admissions. The incidence of fragility fractures requiring surgery has not changed. Appropriate provision in theatres should remain in place to ensure these patients can be managed as a surgical priority. DIY-related hand injuries have increased which has led to an increased in nerve injuries requiring intervention

This single centre study was a prospective analysis from 2000 to 2008, aiming to explore and characterise the incidence and management of orthopaedic injuries sustained from motorcycle-related accidents in children under 16 years of age in Far North Queensland. In addition, it aimed to recognise factors contributing to crash occurrence, injury pattern and severity.

Prospective survey data has been collected for the past eight years looking at various aspects of non-fatal motorcycle injuries in children up to the age of 16 years who present to Cairns Base Hospital. The study incorporated a simple 12-point questionnaire that was completed upon the child's first presentation to the hospital in either an in- or out-patient clinical setting. The aspects addressed by the survey included: number of accidents, use of safety gear, experience level, injury and management, and cause of the accident. Little research has been conducted on characterising the nature and occurrence of off-road motorcycle accidents in children and adolescents.

A total of 238 children were admitted to Cairns Base Hospital with injuries related to motorcycle accidents. The results of 210 children who sustained orthopaedic injuries are presented. Motorcycle accidents involving children were responsible for over 340 presentations to the Emergency department and for a total of more than 500 hospital bed-days upon admission.

The majority of accidents occurred off-road with over 40% on public property. An average of 11% of riders was female.

This study gives evidence that off-road motorcycle accidents in children are the result of inexperience, utilise a significant proportion of our orthopaedic resources, and that programs and policies directed at reducing the number of injuries from off-road motorcycle riding need implementation.

Background:

The outcomes of open tibial fractures in a paediatric population are reported.

Salter-Harris II fractures of the distal tibia affect children frequently, and when they are displaced present a treatment dilemma. Treatment primarily aims to restore alignment and prevent premature physeal closure, as this can lead to angular deformity, limb length difference, or both. Current literature is of poor methodological quality and is contradictory as to whether conservative or surgical management is superior in avoiding complications and adverse outcomes. A state of clinical equipoise exists regarding whether displaced distal tibial Salter-Harris II fractures in children should be treated with surgery to achieve anatomical reduction, or whether cast treatment alone will lead to a satisfactory outcome. Systematic review and meta-analysis has concluded that high-quality prospective multicentre research is needed to answer this question. The Outcomes of Displaced Distal tibial fractures: Surgery Or Casts in KidS (ODD SOCKS) trial, funded by the National Institute for Health and Care Research, aims to provide this high-quality research in order to answer this question, which has been identified as a top-five research priority by the British Society for Children’s Orthopaedic Surgery.

Aims. This observational study examines the effect of the COVID-19 pandemic upon the paediatric trauma burden of a district general hospital. We aim to compare the nature and volume of the paediatric trauma during the first 2020 UK lockdown period with the same period in 2019. Methods. Prospective data was collected from 23 March 2020 to 14 June 2020 and compared with retrospective data collected from 23 March 2019 to 14 June 2019. Patient demographics, mechanism of injury, nature of the injury, and details of any surgery were tabulated and statistically analyzed using the independent-samples t-test for normally distributed data and the Mann-Whitney-U test for non-parametric data. Additionally, patients were contacted by telephone to further explore the mechanism of injury where required, to gain some qualitative insight into the risk factors for injury. Results. The 2020 lockdown resulted in 30% fewer paediatric trauma presentations (441 vs 306), but no significant change in the number of patients requiring surgery (47 vs 51; p = 0.686). Trampolining injuries increased in absolute numbers by 168% (p < 0.001), almost four times more common when considered as percentage of all injuries observed in 2020 vs 2019. There was a decrease in high energy trauma from road traffic accidents and falls from height (21.5% decrease, p < 0.001). Despite a shift towards more conservative treatment options, trampolining injuries continued to require surgery in similar proportions (19.4 vs 20%; p = 0.708). Qualitative investigation revealed that the most common risk factor for trampolining injury was concurrent usage, especially with an older child. Conclusion. COVID-19 lockdown has resulted in a decrease in paediatric orthopaedic presentations and high energy trauma. However, due to a marked increase in home trampolining injuries, and their unchanged requirement for surgery, there has been no change in the requirement for surgery during the lockdown period. As home exercise becomes more prevalent, a duty of public health falls upon clinicians to advise parents against trampoline usage. Cite this article: Bone Jt Open 2021;2(2):86–92

The management of children’s fractures has evolved as a result of better health education, changes in lifestyle, improved implant technology and the changing expectations of society. This review focuses on the changes seen in paediatric fractures, including epidemiology, the increasing problems of obesity, the mechanisms of injury, non-accidental injuries and litigation. We also examine the changes in the management of fractures at three specific sites: the supracondylar humerus, femoral shaft and forearm. There has been an increasing trend towards surgical stabilisation of these fractures. The reasons for this are multifactorial, including societal expectations of a perfect result and reduced hospital stay. Reduced hospital stay is beneficial to the social, educational and psychological needs of the child and beneficial to society as a whole, due to reduced costs.

Aims. Following the introduction of national standards in 2009, most major paediatric trauma is now triaged to specialist units offering combined orthopaedic and plastic surgical expertise. We investigated the management of open tibia fractures at a paediatric trauma centre, primarily reporting the risk of infection and rate of union. Patients and Methods. A retrospective review was performed on 61 children who between 2007 and 2015 presented with an open tibia fracture. Their mean age was nine years (2 to 16) and the median follow-up was ten months (interquartile range 5 to 18). Management involved IV antibiotics, early debridement and combined treatment of the skeletal and soft-tissue injuries in line with standards proposed by the British Orthopaedic Association. Results. There were 36 diaphyseal fractures and 25 distal tibial fractures. Of the distal fractures, eight involved the physis. Motor vehicle collisions accounted for two thirds of the injuries and 38 patients (62%) arrived outside of normal working hours. The initial method of stabilisation comprised: casting in nine cases (15%); elastic nailing in 19 (31%); Kirschner (K)-wiring in 13 (21%); intramedullary nailing in one (2%); open reduction and plate fixation in four (7%); and external fixation in 15 (25%). Wound management comprised: primary wound closure in 24 (39%), delayed primary closure in 11 (18%), split skin graft (SSG) in eight (13%), local flap with SSG in 17 (28%) and a free flap in one. A total of 43 fractures (70%) were Gustilo-Anderson grade III. There were four superficial (6.6%) and three (4.9%) deep infections. Two deep infections occurred following open reduction and plate fixation and the third after K-wire fixation of a distal fracture. No patient who underwent primary wound closure developed an infection. All the fractures united, although nine patients required revision of a mono-lateral to circular frame for delayed union (two) or for altered alignment or length (seven). The mean time to union was two weeks longer in diaphyseal fractures than in distal fractures (13 weeks versus 10.8 weeks, p = 0.016). Children aged > 12 years had a significantly longer time to union than those aged < 12 years (16.3 weeks versus 11.4 weeks, p = 0.045). The length of stay in hospital for patients with a Gustilo-Anderson grade IIIB fracture was twice as long as for less severe injuries. . Conclusion. Fractures in children heal better than those in adults. Based on our experience of deep infection we discourage the use of internal fixation with a plate for open tibial fractures in children. We advocate aggressive initial wound debridement in theatre with early definitive combined orthopaedic and plastic surgery in order to obtain skeletal stabilisation and soft-tissue cover.

Aims. To determine the impact of COVID-19 on orthopaediatric admissions and fracture clinics within a regional integrated care system (ICS). Methods. A retrospective review was performed for all paediatric orthopaedic patients admitted across the region during the recent lockdown period (24 March 2020 to 10 May 2020) and the same period in 2019. Age, sex, mechanism, anatomical region, and treatment modality were compared, as were fracture clinic attendances within the receiving regional major trauma centre (MTC) between the two periods. Results. Paediatric trauma admissions across the region fell by 33% (197 vs 132) with a proportional increase to 59% (n = 78) of admissions to the MTC during lockdown compared with 28.4% in 2019 (N = 56). There was a reduction in manipulation under anaesthetic (p = 0.015) and the use of Kirschner wires (K-wires) (p = 0.040) between the two time periods. The median time to surgery remained one day in both (2019 IQR 0 to 2; 2020 IQR 1 to 1). Supracondylar fractures were the most common reason for fracture clinic attendance (17.3%, n = 19) with a proportional increase of 108.4% vs 2019 (2019 n = 20; 2020 n = 19) (p = 0.007). While upper limb injuries and falls from play apparatus, equipment, or height remained the most common indications for admission, there was a reduction in sports injuries (p < 0.001) but an increase in lacerations (p = 0.031). Fracture clinic management changed with 67% (n = 40) of follow-up appointments via telephone and 69% (n = 65) of patients requiring cast immobilization treated with a 3M Soft Cast, enabling self-removal. The safeguarding team saw a 22% reduction in referrals (2019: n = 41, 2020: n = 32). Conclusion. During this viral pandemic, the number of trauma cases decreased with a change in the mechanism of injury, median age of presentation, and an increase in referrals to the regional MTC. Adaptions in standard practice led to fewer MUA, and K-wire procedures being performed, more supracondylar fractures managed through clinic and an increase in the use of removable cast.

Aims. COVID-19 necessitated abrupt changes in trauma service delivery. We compare the demographics and outcomes of patients treated during lockdown to a matched period from 2019. Findings have important implications for service development. Methods. A split-site service was introduced, with a COVID-19 free site treating the majority of trauma patients. Polytrauma, spinal, and paediatric trauma patients, plus COVID-19 confirmed or suspicious cases, were managed at another site. Prospective data on all trauma patients undergoing surgery at either site between 16 March 2020 and 31 May 2020 was collated and compared with retrospective review of the same period in 2019. Patient demographics, injury, surgical details, length of stay (LOS), COVID-19 status, and outcome were compared. Results. There were 1,004 urgent orthopaedic trauma patients (604 in 2019; 400 in 2020). Significant reductions in time to theatre and LOS stay were observed. COVID-19 positive status was confirmed in 4.5% (n = 18). The COVID-19 mortality rate was 1.8% (n = 7). Day-case surgery comprised 47.8% (n = 191), none testing positive for COVID-19 or developing clinically significant COVID-19 symptoms requiring readmission, at a minimum of 17 days follow-up. Conclusion. The novel split-site service, segregating suspected or confirmed COVID-19 cases, minimized onward transmission and demonstrated improved outcomes regarding time to surgery and LOS, despite altered working patterns and additional constraints. Day-surgery pathways appear safe regarding COVID-19 transmission. Lessons learned require dissemination and should be sustained in preparation for a potential second wave or, the return of a “normal” non-COVID workload.

Aims. The management of fractures of the medial epicondyle is one of the greatest controversies in paediatric fracture care, with uncertainty concerning the need for surgery. The British Society of Children’s Orthopaedic Surgery prioritized this as their most important research question in paediatric trauma. This is the protocol for a randomized controlled, multicentre, prospective superiority trial of operative fixation versus nonoperative treatment for displaced medial epicondyle fractures: the Surgery or Cast of the EpicoNdyle in Children’s Elbows (SCIENCE) trial. Methods. Children aged seven to 15 years old inclusive, who have sustained a displaced fracture of the medial epicondyle, are eligible to take part. Baseline function using the Patient-Reported Outcomes Measurement Information System (PROMIS) upper limb score, pain measured using the Wong Baker FACES pain scale, and quality of life (QoL) assessed with the EuroQol five-dimension questionnaire for younger patients (EQ-5D-Y) will be collected. Each patient will be randomly allocated (1:1, stratified using a minimization algorithm by centre and initial elbow dislocation status (i.e. dislocated or not-dislocated at presentation to the emergency department)) to either a regimen of the operative fixation or non-surgical treatment. Outcomes. At six weeks, and three, six, and 12 months, data on function, pain, sports/music participation, QoL, immobilization, and analgesia will be collected. These will also be repeated annually until the child reaches the age of 16 years. Four weeks after injury, the main outcomes plus data on complications, resource use, and school absence will be collected. The primary outcome is the PROMIS upper limb score at 12 months post-randomization. All data will be obtained through electronic questionnaires completed by the participants and/or parents/guardians. The NHS number of participants will be stored to enable future data linkage to sources of routinely collected data (i.e. Hospital Episode Statistics). Cite this article: Bone Jt Open 2024;5(1):69–77

Tranexamic acid (TXA) is an antifibrinolytic that can prevent clot breakdown. Trauma patients often have coagulopathy which can cause mortality due to bleeding. The purpose of this review is to investigate the efficacy of TXA in reducing mortality in major trauma and secondly to look at patient's outcomes when using TXA in trauma. Searches were performed in PUBMED, EMBASE and other databases for randomised controlled trials (RCT) and observational studies. The author searched for all relevant evidence on the use of TXA in major trauma. Relevant studies were assessed for quality using the Cochrane's Collaboration's tool for assessing risk of bias. Eight relevant studies were identified from the search, 3 randomised controlled trials (RCTs) and 5 observational studies were identified. Five of the 8 studies found a significance in mortality with TXA use. Three showed TXA reduced mortality including the high quality level I evidence, CRASH 2 study. Three studies found no significance on mortality. There appears to be no increased risk of VOE with TXA however results from the studies varied. No study reported any adverse events due to TXA use. There does not appear to be any significant benefit of TXA use in TBI but a trend towards lower mortality. There is a role in paediatric trauma despite evidence from only 2 observational studies. There is a high quality RCT to suggest the use of TXA in trauma patients with supporting evidence from observational studies. The outcomes in TBI are unclear. It may be beneficial in paediatric use but there is currently no level 1 evidence in paediatrics to support this. Further prospective studies looking specifically at role in TBI and paediatric trauma are required to support routine use in these specific populations

Introduction and Objective. The most common paediatric orthopaedic injury requiring hospital admission is a femoral fracture. There is debate regarding the optimal surgical technique for fixing femoral diaphyseal fractures in children aged 4 to 12 years. The National Institute for Health and Care Excellence (NICE) and the American Academy of Orthopaedic Surgeons (AAOS) have issued relevant guidelines, however, there is limited evidence to support these. The aim of this study was to conduct a systematic review and meta-analysis to compare the complication rate following flexible intramedullary nailing (FIN), plate fixation and external fixation (EF) for traumatic femoral diaphyseal fractures in children aged 4 to 12. Materials and Methods. We searched MEDLINE, EMBASE and CENTRAL databases for interventional and observational studies. Two independent reviewers screened, assessed quality and extracted data from the identified studies. The primary outcome was the risk of any complication. Secondary outcomes assessed the risk of pre-specified individual complications. Results. Nine randomised controlled trials (RCTs) and 19 observational studies (six prospective and 13 retrospective) fulfilled the eligibility criteria. Within the RCTs, five analysed FIN (n=161), two analysed plates (n=51) and five analysed EF (n=168). Within the observational studies, 13 analysed FIN (n=610), seven analysed plates (n=214) and six analysed EF (n=153). The overall risk of complications was lower following plate fixation when compared to FIN fixation (RR 0.45, 95% CI 0.28 to 0.73, p=0.001) in the observational studies. The overall risk of complications was higher following EF when compared to FIN fixation in both RCTs (RR 1.94, 95% CI 1.25 to 3.01, p=0.003) and observational studies (RR 1.97, 95% CI 1.50 to 2.58, p<0.001). The overall risk of complications was higher following EF when compared to plate fixation in both RCTs (RR 7.42, 95% CI 1.84 to 29.98, p=0.005) and observational studies (RR 4.39, 95% CI 2.64 to 7.30, p<0.001). Conclusions. Although NICE and the AAOS recommend FIN for femoral diaphyseal fractures in children aged 4 to 12, this study reports a significantly decreased relative risk of complications when these injuries are managed with plates. Our findings provide valuable information to healthcare professionals who are involved in discussing the risk and benefits of different management options with patients and their families. The overall quality of evidence is low, highlighting the need for a rigorous prospective multicentre randomised trial at low risk of bias due to randomisation and outcome measurement to identify if any fixation technique is superior

Introduction. Patients presenting with osteoarthritis as late sequelae following pediatric hip trauma have few options aside from standard Total Hip Replacement (THR). For younger more active patients, Hip Resurfacing Arthroplasty (HRA) can be offered as an alternative. HRA has been performed in the United States over the past decade and allows increased bone preservation, decreased hip dislocation rates versus THR, and potential to return to full activities. Patients presenting with end-stage hip arthritis as following prior pediatric trauma or disease often have altered hip morphology making HRA more complicated. Often Legg-Calve-Perthes (LCP) patients present with short, wide femoral necks, and femoral head distortion including coxa magna or coxa plana. There often can be acetabular dysplasia in conjunction with the proximal femoral abnormalities. Slipped Capital Femoral Epiphysis (SCFE) patients have an alteration of the femoral neck and head alignment, which can make reshaping the femoral head difficult. In particular, the femoral head is rotated medially and posteriorly, reducing the anterior and lateral offset. We present a cohort of 20 patients, with history of a childhood hip disorder (SCFE or LCP), who underwent HRA to treat end-stage arthritis. Fifty percent had prior pediatric surgical intervention at an average age of 11. Method. After Institutional Review Board approval, data was reviewed retrospectively on patients with pediatric hip diseases of SCFE and LCP who underwent HRA using the Birmingham Hip Resurfacing (BHR) by a single orthopaedic surgeon at a teaching institution. Harris Hip Scores (HHS), plain radiographs and blood metal ion levels were reviewed at routine intervals (12 months and annually thereafter). Those who had not returned for recent follow-up were contacted via telephone survey for a modified HHS. Results. Twenty patients had mean follow up of 2.8 years (range 1–7 years). Twelve had LCP and 8 SCFE. Median implant duration was 2.4 years. One-year metal ion testing revealed median chromium level of 2.3 ppb and median Cobalt level of 1.5 ppb. At one-year follow up, plain radiographs demonstrated all patient implants to be well-fixed, without radiolucent lines or osteolysis. Two patients at three and five-year follow-up exhibited heterotopic ossification. Mean HHS for LCP at 6 weeks post-operative was 88, and 98 at one year. Mean HHS for SCFE at 6 weeks post-operative was 77.5, and 98.6 at one year. LLD was significantly improved with an average pre-operative LLD of 12.6 mm and post op of 2.6 mm (p-value <0.001). At most recent follow-up, all retained their implants with overall average HHS of 98. Conclusion. At minimum of one-year following HRA, an increase in functional outcomes is found in patients who underwent HRA for osteoarthritis associated with LCP and SCFE with a mean HHS of 98. No increase was found in complications including femoral neck fracture or implant loosening despite technical challenges of the procedure related to proximal femoral morphologic abnormalities, or presence of acetabular dysplasia [Fig 1]

Aims. The follow-up interval of a study represents an important aspect that is frequently mentioned in the title of the manuscript. Authors arbitrarily define whether the follow-up of their study is short-, mid-, or long-term. There is no clear consensus in that regard and definitions show a large range of variation. It was therefore the aim of this study to systematically identify clinical research published in high-impact orthopaedic journals in the last five years and extract follow-up information to deduce corresponding evidence-based definitions of short-, mid-, and long-term follow-up. Methods. A systematic literature search was performed to identify papers published in the six highest ranked orthopaedic journals during the years 2015 to 2019. Follow-up intervals were analyzed. Each article was assigned to a corresponding subspecialty field: sports traumatology, knee arthroplasty and reconstruction, hip-preserving surgery, hip arthroplasty, shoulder and elbow arthroplasty, hand and wrist, foot and ankle, paediatric orthopaedics, orthopaedic trauma, spine, and tumour. Mean follow-up data were tabulated for the corresponding subspecialty fields. Comparison between means was conducted using analysis of variance. Results. Of 16,161 published articles, 590 met the inclusion criteria. Of these, 321 were of level IV evidence, 176 level III, 53 level II, and 40 level I. Considering all included articles, a long-term study published in the included high impact journals had a mean follow-up of 151.6 months, a mid-term study of 63.5 months, and a short-term study of 30.0 months. Conclusion. The results of this study provide evidence-based definitions for orthopaedic follow-up intervals that should provide a citable standard for the planning of clinical studies. A minimum mean follow-up of a short-term study should be 30 months (2.5 years), while a mid-term study should aim for a mean follow-up of 60 months (five years), and a long-term study should aim for a mean of 150 months (12.5 years). Level of Evidence: Level I. Cite this article: Bone Jt Open 2021;2(5):344–350

The objectives of this study are to ascertain primary caregivers' understanding of risks associated with home trampoline use; to educate caregivers in regard to documented literature based risks associated with home trampoline use; and to evaluate if this information will have any influence on their future regulation of home trampoline use for their children. One hundred primary caregivers of patients treated in the paediatric orthopaedic surgery outpatient clinic at London Health Sciences centre were surveyed. All caregivers in clinic were invited to participate. The only exclusion criteria was the inability to provide consent. Caregivers' baseline perceptions on the risks associated with home trampoline use were assessed using a questionnaire. Caregivers then received an information pamphlet outlining documented trampoline safety data. They were then sent the same questionnaire to complete within one week of reading the pamphlet. Using our research electronic database capture (Redcap), the results of the surveys were compiled and analysed using spss 22, paired t-test and repeated measures anova. A sample size of 55 was calculated to result in a power of 80%. Of primary caregivers surveyed, 36% owned a home trampoline, and only 5% had personal experiences with their child sustaining a trampoline injury. Pre-education, when caregivers were asked on a scale of one (not dangerous) to 10 (very dangerous) how dangerous they felt a trampoline was for their child, the average response was six. Post-education, this number changed to eight. Providing education to primary caregivers significantly changed their perceptions on all sections of the questionnaire, yet 47% of primary caregivers were willing to allow their child to use a trampoline at home despite their new understanding of trampoline injury and safety. Providing education to primary caregivers significantly changed their perceptions on all trampoline safety questions, indicating effective comprehension. Despite caregivers' understanding of the risks associated with home trampoline use, approximately half of the study population continue to permit this activity for their children. There is potential to reduce paediatric orthopaedic injuries associated with home trampoline use if safer trampoline related practices are implemented based on information provided

Compartment syndrome (CS), a serious complication in paediatric trauma, can be prevented by timely diagnosis and adequate therapy. From 1990 to 2000 we treated 22 patients with suspected CS in the arm. Incision into the intrafascial spaces of nine forearms and three hands confirmed the diagnosis. In 10 patients, fracture had caused the syndrome, and in two, the cause was contusion. In two patients the CS resulted from incorrect treatment procedures. We also treated 22 patients with suspected CS in the lower limb. The diagnosis was confirmed in 15. Incision into the intrafascial spaces was performed during treatment, 13 times on the crus and twice on the femur. Fractures were always the primary cause. In the upper limb outcomes were good. One patient developed a Volkman’s contracture but this was only disfiguring. Some patients treated for lower limb CS had cosmetic after-effects, but only one patient, in whom CS was diagnosed late, had functional after-effects. We advocate permanent monitoring of intrafascial pressures, using piezoelectric sensors, and timely performance of adequate dermofasciotomies

The aim of this study was to establish the consensus of opinion amongst trauma surgeons for the management of displaced supracondylar fractures of the humerus in children. We carried out a postal questionnaire involving 130 orthopaedic surgeons with an interest in paediatric trauma. They were identified as being members of the British Society for Children’s Orthopaedic Surgery. We received a response rate of 65%. One third of respondents believe that in uncomplicated fractures, reduction should occur within 6 hours of injury and one half felt that ‘pulseless’ fractures should be treated in the same time frame. 60% said they would explore a pulseless arm after midnight, but only 20% would reduce and stabilise uncomplicated fractures. 82% of surgeons stabilise displaced grade III fractures with K wires, of these, the majority would use a‘crossed’ configuration. If after stabilisation the arm remained pulseless, only 16% said they would explore the brachial artery immediately, 23.5% would seek a vascular opinion and 60.5% of surgeons would observe for 24 hours. If the arm remained pulseless but pink after 24 hours, the majority of surgeons would continue to observe and rely on collateral circulation for distal perfusion. The majority of surgeons would stabilise displaced supracondylar fractures as soon as possible but not after midnight unless the arm was pulseless. If the hand remained pink but pulseless, most felt that continued observation beyond 24 hours was acceptable

Complex injuries of upper extremity are among the most challenging cases for the treating physician, especially when comminuted fractures, neurovascular injuries or extensive soft tissue loss are accompanied with. Reconstruction of the skeleton is usually very difficult since plates, screws, or external fixation do not always provide sufficient stability. Recently, flexible titanium intramedullary nails that initially developed for pediatric trauma, were introduced in treatment of open and complex injuries of upper extremity. From 1995 – 2001 20 patients (16 male, 4 female) with a mean age 28 years (15–60 years) were managed at our department with flexible titanium intramedullary nailing. 12 sustained forearm fractures, humeral ones, as well as 4 concomitant fractures of forearm and humerus.Nailing was performed either closed with image intensifier or open through the wound with minimal stripping. Postoperatively a splint was applied. Rehabilitation regime was adjusted to soft tissue care; when severe soft tissue wasn’t encountered, early mobilization of the arm was applied. Union rate was conceivably high, in a relative short time. In 3 cases of segmental fractures of radius, nail removal and subsequent fixation with plate and screws due to nonunion of distal site, was necessitated. Operative technique is simple, fast and reliable providing satisfactory reduction, stable fixation with minimal further tissue trauma and mostly early mobilization

Aim of study: Finding the differences between classic distal humeral physeal injuries as radial condylar phy-seal injury, intercondylar fractures or apophyseal injuries and separations of the entire distal humeral epiphysis. To identify a classification of this serious injury according to the age. Material: Children treated in the Regional Paediatric Trauma Centre, Thomayer Teaching Hospital, Prague during the period of last ten years (1992 – 2001): 14.708 patients with fractures; 1.249 from them with humeral fractures, 875 with distal humeral fractures and 29 with separation of distal humeral epiphysis. Methods: Retrospective study of all cases with separation of the entire distal humeral epiphysis, diagnostic imaging, methods of treatment and results. Especially pitfalls and their reasons are followed. Results: Eight fracture-separations were misdiagnosed or not recognised. One half of injuries was operated on either by miniinvasive or open surgery. In all misdiag-nosed cases serious sequels were recorded. Conclusions: Separation of the entire distal humeral epiphysis has several forms according to ossification of the humerus. The most difficult diagnosis is in young children with cartilaginous periarticular skeleton invisible on X-rays. Stress investigation in general anaesthesia with the use of an image Intensifier or ultrasound imaging can be helpful. However, the knowledge of this type of skeletal injury is not welll known and due to frequent complications can be considered as one of most dangerous fractures in children

Aim of study Setting an investigation and therapeutical algorythm in paediatric patients with a distal tibiofibular joint injury. Material: The authors present their clinical material collected during the period of last five years (from 1997 to 2001). 222 children with physeal injury of the distal tibia and/or fibula were treated in the Regional Paediatric Trauma Centre in Prague Krè. Methods: In all patients with an injury of the ankle joint, a plain X-ray scanning in two basic planes was performed. In any doubts oblique views or an X-ray scan of the ankle joint in a stress position were added. In some patients it was necessary to complete the investigation by CT scans. Results: Only 9 % of all 222 selected patients sustained the distal tibiofibular joint injury. In 85 % of them the skeletal injury was evident (the juvenile Tillaux fracture of Salter’s type 3 or 4). In the rest 15 % (three cases) there was no skeletal trauma visible on neither plain nor oblique X-ray scans but CT scan showed it. Conclusions: Injury to the distal tibiofibular joint is very rare in the growing skeleton. Most of our patients were of premature age. There is a danger of missing this rare but subsequently serious injury. That’s why we recommend the use of CT in all cases of ankle joint injury in children. Children with fractures (juvenile Tillaux fracture) displaced more than 2 mm should be operated on (closed reduction and internal fixation). In two girls we had to stabilise the distal tibiofibular joint due to severe ligamentous injury

Purpose: A single level spine fracture can be dangerous, however a second spine fracture at a different level can add complexity to patient management, and if missed, can result in a significant adverse outcome. Higher rates of multiple noncontiguous spinal injury (MNCSI) have been reported in patients who die from injuries, and with more unstable spinal injuries. The reported incidence in adults is 1.6–34%, but to our knowledge there are no studies examining multiple spine injuries in a pediatric population. Method: A retrospective review of charts at an academic pediatric level 1 trauma center over a 15 year period identified a population with MNCSI. Results: Twenty five (11.8%) out of 211 patients were identified with MNCSI and complete charts and radiographs. The mean age was 10.7 years old. MVC (motor vehicle collision) was the most common mechanism of injury for ages 0–9, while a fall was most common for ages 10–17 years. The mean number of vertebral levels injured was 3.2 and the most common region was the thoracic spine. Patients had a mean of 5.4 (range 1 to 22) intact vertebral levels between injuries. Twenty-four percent of patients with MNCSI had a neurologic deficit compared to 9.7% in patients with single level or contiguous injuries. This was statistically significant; risk ratio was 2.48 [1.09, 5.65]. Seven (78%) of 9 patients aged 0–9 suffered an associated injury; most commonly a visceral injury. The mortality rate was 8.0% in patients with MNCSI compared to 2.7% in patients with a single level injury. Conclusion: We report a 12 % incidence of MNCSI in a pediatric trauma population. Children with NCSI were more likely to suffer neurologic injury than with a single level injury. Younger patients with MNCSI’s had a high rate of associated injuries. A higher mortality rate was seen in patients with MNCSI (not statistically significant). MNCSI’s can occur in conjunction with SCIWORA’s in the flexible pediatric spine. Clinicians must be aware of the incidence of NCSI’s in children, as well as their associations

Subtrochanteric femoral fractures are uncommon in children, consequently there are no good treatment guidelines in the literature. This series reviewed all subtrochanteric femur fractures in skeletally immature adolescents older than ten years treated at a pediatric trauma center. There were fifteen adolescents with open growth plates. Treatment was non-operative in four and operative in eleven. Each of the adolescents treated non-operatively developed an unsatisfactory result, while eight of the eleven who were treated operatively experienced a satisfactory result. These results suggest improved outcome with operative treatment in this patient population. It was the purpose of this study to describe treatment options and make recommendations for management of subtrochanteric femur fractures among skeletally immature adolescents older than ten years of age. This series consisted of a retrospective review of all cases of subtrochanteric fractures in adolescents with open growth plates. The outcome was classified on the basis of radiographic criteria. There were fifteen adolescents with an average age of thirteen years and one month. The average length of follow-up was two years and nine months. Treatment was non-operative in four and operative in eleven, utilizing a variety of fixation devices. There was fracture union in each case, although there was one delayed union. Complications included limb length discrepancy in three, each of which were treated non-operatively, one transient peroneal nerve palsy and asymptomatic heterotopic ossification. One adolescent, treated with a rigid intramedullary rod, developed avascular necrosis of the femoral head. The result was unsatisfactory in each of the non-operative cases, while eight of the eleven treated operatively developed satisfactory results. Children less than ten years of age may be treated non-operatively. However, in skeletally immature adolescents, operative treatment resulted in improved outcomes. Rigid intramedullary fixation is contraindicated in skeletally immature adolescents due to the risk of avascular necrosis of the femoral head. This series is the first to emphasize treatment and make management recommendations regarding subtrochanteric fractures in this age group. Internal fixation is more effective than non-operative treatment for subtrochanteric femur fractures in skeletally immature adolescents, however the ideal method of fixation requires further study

Purpose of the study: Appropriate treatment of displaced supracondylar fractures of the distal humerus in children remains a controversial topic. Blount reduction followed by percutaneous or open pin fixation have been widely used. The purpose of this study was to analyze outcome after open surgical treatment of these fractures in pediatric trauma victims. Material and methods: The study included all pediatric patients who underwent surgical treatment for displaced supracondylar fractures of the distal humerus over a ten year period. Fractures were classified III or IV according to Lagrange and Rigault. Cross pinning was used in all cases, via a posterior approach or a double lateral and medial approach. The mechanism of the fracture and pre- and postoperative vascular and neurological complications were noted. The long-term assessment included standard x-rays of the elbow joint (ap and lateral views) and a physical examination to search for misalignment and residual neurological disorders. Results: We identified 110 patients, 61 boys and 49 girls, mean age 7.61 years (range 2–15 years). There were 96 grade IV fractures and 24 grade III. Mechanisms were: sports accident (n=44), fall from height (n=36), fall from own height (n=30). A neurological complication was observed in 29 children, skin opening in three and regressive vascular damage in six. A posterior approach was used for 95 patients and a double approach for 15. There was one revision for secondary displacement. Five patients developed transient paresthesia of the ulnar nerve which resolved without sequela. Three patients presented a moderately hypertrophic or deformed callus which had little functional impact. One patient with an open fracture required surgerical arthrolysis for stiffness six months after fracture. Discussion and conclusion: Open surgery is a very reliable treatment for supracondylar elbow fractures with a low rate of short- and long-term complications. Ulnar nerve palsy, the classical complication of percutaneous cross pinning, can be attributed to the medial pin (7–16% of cases in the literature). The Blount method and Judet or Métaizeau fixations can sometimes be complicated by secondary displacement or a deformed callus, complications which were almost never observed in our series. The results obtained in this series favor our approach for open surgery for the treatment of displaced supracondylar fractures of the distal humerus in children

Summary Statement. Magnesium has a number of qualities suitable for bioresorbable metallic implants. However, high corrosion rate and formation of hydrogen gas can compromise its performance. Combining magnesium with calcium phosphate improves magnesium's biocompatibility by decreasing gas formation and increasing bone remodeling. Introduction. Clinical problems like risk of postoperative infection and increased incidence of pediatric trauma requiring surgical intervention raised the need for temporary orthopedic implants that would resorb after the bone healing is complete. This would decrease high costs associated with repeated surgeries, minimise recovery times, decrease the risk of postoperative infections, and thus promote higher quality of life to the patients. The specific requirement for orthopedic implants, aside from being bioresorbable, is the ability to bear high loads. Magnesium was suggested as a suitable material for these purposes because it is biocompatible; has excellent mechanical properties; is natural for human body, and seems to stimulate new bone formation. However, an important problem with magnesium is high corrosion rate with consistent hydrogen gas formation on contact with fluids. This in vivo study focuses on investigation of new magnesium-based implants specifically designed to minimise hydrogen gas formation. Methods. Four types of degradable magnesium-based materials were tested for biocompatibility in this study: Magnesium-Hydroxyapatite implants (Mg-HA); Magnesium-Calcium Phosphate Cement (Mg-CPC); alloy of 96% Magnesium and 4% Yttrium (W4); and 99.95% pure magnesium which was a control group. Biomaterials were operated into 33 male New Zealand white rabbits. The animals were sacrificed after 6 and 12 weeks after which the samples were embedded into Epon, paraffin and Technovit resin. The staining was done with TRAP, hematoxylin eosin and toluidine blue. Additionally, TEM and immunohistochemical analysis were performed. The data was analysed both qualitatively and quantitatively by Statistical Package for the Social Sciences (SPSS, v18, SPSS Inc, Chicago, IL). Results. Mg-CPC showed the best performance in this study. New bone formation was significantly more prevalent in Mg-CPC group while gas formation was significantly less comparing to the other materials. Mg-HA had the worst properties due to extremely fast degradation already at 6 weeks, the least amount of new bone formation, and the lowest amount of osteoclasts and multinucleated cells in the implantation site. Pure magnesium and W4 had similar properties: both were surrounded with corrosion layer, and the gas volumes were significantly higher in these two groups compared to other materials. Discussion/Conclusion. New bone was seen forming either in direct contact to implants or around the gas bubbles. The later can be interpreted as body's reaction to protect from gas spreading. Mg-HA's degradation rate was far too fast and this is unacceptable for orthopedic fractures which often require several months to heal and that experience much load. Pure magnesium and W4 although maintained their integrity, were surrounded by corrosion layer and gas bubbles that were bigger in diameter than in the other groups. These findings could compromise implant stability. Mg-CPC was the most biocompatible; it showed significantly higher amount of osteoclasts which is a first sign of bone remodeling. It had also significantly less gas production than other groups. These results show that magnesium's biocompatibility could be improved by combining it with other suitable materials, such as calcium phosphate

There is little data regarding the epidemiology of childhood injury in Ireland. This is difficult to obtain retrospectively. The aim of this study was to prospectively evaluate paediatric trauma referrals to our department, describe their epidemiology, and identify potentially preventable injuries in children. Our unit at the National Childrens Hospital is located in a growing suburban area in South Dublin. Injury surveillance was conducted on orthopaedic referrals by distributing a form to parents of children attending fracture clinics or admitted acutely for surgery. Parents were asked for demographic information, and a brief description of the injury in terms of location, mechanism and circumstance of injury. Diagnosis was completed by the attending doctor and data was transferred to a computerised database. We analyzed data from the 397 referrals in the first month of this study. The mean age of injury was 9.1 years and the male: female ratio was 1.3:1. The peak hour of injury was 7 – 8 pm. Only 33% of injuries occured during the weekend. 62% of injuries were due to falls, usually form the standing position. The most common location for injury was in or about the home (39%), and other notable locations were school (16%) and sportsfield (14%). 61% of falls greater than 1 metre occurred at home, mostly from walls and childrens slides. 20% of injuries occurred while participating in organized sport, including Gaelic football, soccer and hurling. Injuries occuring during unsupervised sport were more likely to need surgery. Domestic ‘bouncing castles’ and trampolines, increasingly popular in our area, were a notable cause of significant trauma to the upper limb. 7% of injuries occurred by falling from a bicycle, but vehicular road traffic accident was an uncommon cause of injury. 263 children had confirmed fractures, other injuries consisting largely of sprains to the ankle, elbow and wrist. Predictably, the bones most commonly fractured were the radius (41%), phalanges (15%) and humerus (11%). 20% of fractures needed operative management, mostly forearm manipulation under anaesthesia. 63% of operative cases were performed outside of normal working hours. Several countries utilise injury surveillance as a means of development and evaluation of injury prevention strategies. In our initial study, basic surveillance has outlined local characteristics of chilhood trauma, and some trends were noted. In particular, we suggest home injuries need further attention in out catchment area

Purpose of study. To review the treatment and outcomes of paediatric pelvic ring injuries in the UK. Methods and results. We performed a retrospective review of all pelvic fracture admissions to an English paediatric major trauma centre (MTC) from 2012 to 2016. A total of 29 patients were admitted with pelvic ring injuries with a mean age of 11 years (4- 16yrs). Road traffic accident was the mechanism in majority (72%), followed by fall from height (24%). Femoral shaft fracture was present in 5 (17%), head injury in 5 (17%), chest injuries in 5 (17%) and bladder injury in one child. 48% patients needed surgical procedures for fractures or associated injuries. We differentiated injuries according to the classification system of Torode and Zeig. 17% were Type A, 3% Type B, 48% Type C and 31% Type D. Almost all (93%) patients were treated conservatively. 51% of patients were allowed to mobilize full weight bearing after a period of bed rest. Non-weight bearing mobilization was recommended for fractures extending into the acetabulum, sacral fractures, unstable fracture patterns or associated fractures (neck of femur, femoral shaft and tibial shaft). Surgical fixation occurred in two patients. Both of these patients had significantly displaced Type D fractures. Only 44% of patients were back to sports at six months. Conclusions. Pelvic ring injuries are rare within the paediatric population and are associated with a high incidence of concomitant injury and significant functional morbidity. Their treatment should involve a multidisciplinary approach, which includes specialist in the care of pelvic trauma

Aims

Periacetabular osteotomy (PAO) is the preferred treatment for symptomatic acetabular dysplasia in adolescents and young adults. There remains a lack of consensus regarding whether intra-articular procedures such as labral repair or improvement of femoral offset should be performed at the time of PAO or addressed subsequent to PAO if symptoms warrant. The purpose was to determine the rate of subsequent hip arthroscopy (HA) in a contemporary cohort of patients, who underwent PAO in isolation without any intra-articular procedures.

Aims

The aim of this study is to determine the effects of the UK lockdown during the COVID-19 pandemic on the orthopaedic admissions, operations, training opportunities, and theatre efficiency in a large district general hospital.

Aims

Open tibial fractures are limb-threatening injuries. While limb loss is rare in children, deep infection and nonunion rates of up to 15% and 8% are reported, respectively. We manage these injuries in a similar manner to those in adults, with a combined orthoplastic approach, often involving the use of vascularised free flaps. We report the orthopaedic and plastic surgical outcomes of a consecutive series of patients over a five-year period, which includes the largest cohort of free flaps for trauma in children to date.

Aims

We aimed to evaluate the health-related quality of life (HRQoL) in children with supracondylar humeral fractures (SCHFs), who were treated following the recommendations of the Paediatric Comprehensive AO Classification, and to assess if HRQoL was associated with AO fracture classification, or fixation with a lateral external fixator compared with closed reduction and percutaneous pinning (CRPP).

Aims

We aim to objectively assess the impact of COVID-19 on mean total operative cases for all indicative procedures (as outlined by the Joint Committee on Surgical Training (JCST)) experienced by orthopaedic trainees in the deanery of the Republic of Ireland. Subjective experiences were reported for each trainee using questionnaires.

Aims

The exact risk to patients undergoing surgery who develop COVID-19 is not yet fully known. This study aims to provide the current data to allow adequate consent regarding the risks of post-surgery COVID-19 infection and subsequent COVID-19-related mortality.
