Olecranon fractures are common injuries representing roughly 5% of pediatric elbow fractures. The traditional surgical management is open reduction and internal fixation with a tension band technique where the pins are buried under the skin and tamped into the triceps. We have used a modification of this technique, where the pins have been left out of the skin to be removed in clinic. The purpose of the current study is to compare the outcomes of surgically treated olecranon fractures using a tension-band technique with buried k-wires (PINS IN) versus percutaneous k-wires (PINS OUT).

We performed a retrospective chart review on all pediatric patients (18 years of age or less) with olecranon fractures that were surgically treated at a pediatric academic center between 2015 to present. Fractures were identified using ICD-10 codes and manually identified for those with an isolated olecranon fracture. Patients were excluded if they had polytrauma, metabolic bone disease, were treated non-op or if a non-tension band technique was used (ex: plate/screws). Patients were then divided into 2 groups, olecranon fractures using a tension-band technique with buried k-wires (PINS IN) and with percutaneous k-wires (PINS OUT). In the PINS OUT group, the k-wires were removed in clinic at the surgeon's discretion once adequate fracture healing was identified. The 2 groups were then compared for demographics, time to mobilization, fracture healing, complications and return to OR.

A total of 35 patients met inclusion criteria. There were 28 patients in the PINS IN group with an average age of 12.8 years, of which 82% male and 43% fractured their right olecranon. There were 7 patients in the PINS OUT group with an average age of 12.6 years, of which 57% were male and 43% fractured their right olecranon. All patients in both groups were treated with open reduction internal fixation with a tension band-technique. In the PINS IN group, 64% were treated with 2.0 k-wires and various materials for the tension band (82% suture, 18% cerclage wire). In the PINS OUT group, 71% were treated with 2.0 k-wires and all were treated with sutures for the tension band. The PINS IN group were faster to mobilize (3.4 weeks (range 2-5 weeks) vs 5 weeks (range 4-7 weeks) p=0.01) but had a significantly higher complications rate compared to the PINS OUT group (6 vs 0, p =0.0001) and a significantly higher return to OR (71% vs 0%, p=0.0001), mainly for hardware irritation or limited range of motion. All fractures healed in both groups within 7 weeks.

Pediatric olecranon fractures treated with a suture tension-band technique and k-wires left percutaneously is a safe and alternative technique compared to the traditional buried k-wires technique. The PINS OUT technique, although needing longer immobilization, could lead to less complications and decreased return to the OR due to irritation and limited ROM.

Introduction

Femoral shaft fractures in children is a serious injury that needs hospitalization, with a high prevalence in the age group 6–8 years old. Various treatment options are available and with a comparable weight of evidence. Submuscular plating provides a dependable solution, especially in length-unstable fractures and heavier kids. We present a novel technique to facilitate and control the reduction intraoperatively, which would allow for easier submuscular plate application.

Supracondylar fractures of the humerus (SCH) are the most common fractures sustained following a fall among children. The majority of these fractures are mild, but the most severe injury types can result in a disruption to the nerves and blood supply resulting in limb threatening injuries and potential life-long disability. Better understanding of mechanisms of injury and child-related factors that influence injury, especially for severe cases, is crucial to identifying best practices and informing policy. We aim to stratify fractures and examine the associated mechanisms and circumstances of injury to identify best practices and inform supportive policy. In doing so, we plan to investigate why some children sustain more severe fractures than others by exploring mechanisms and locations of injury, and risk-taking behaviours.

A prospective, mixed-methods pilot study employing a child-led research design. Our approach links narratives from qualitative photo elicitation interviews (PEI) to mapped images of the locations of injury using geotagged photographs children have taken themselves, complications and injury outcomes, and an assessment of overall risk-taking tendencies.

Participants aged six-12, with the help of their photographs, were able to lay out the events leading up to, including, and following their injury. Much of this information was either not included in their medical charts or was markedly different. Themes included not being able to prevent the injury and being adventurous, as well as becoming more cautious afterwards. These can have applications to the necessity of exploration as well as possibilities to prevent injury or not. Thus, the in-depth, first-person retelling of injury mechanism illustrated the need for mechanistic data and statistics beyond injury location alone. Risk-taking behaviours, as scored by the Sensation Seeking Scale for Children, correlated to injury severity, which is known to be associated with poorer outcomes and long-lasting complications.

PEI of children sustaining SCH fractures in Vancouver reveals mechanisms of injury beyond those previously reported in literature and suggest the feasibility of a large-scale study. PEI in this age group allows for clarifications and a clearer picture of injury mechanism as well as context of injury. These aspects significantly affect our ability to determine the relationship between injury mechanism and injury severity. Mixed-methods analysis of child-directed data as well as quantitative injury demographics reveals unique translational knowledge which can be shared with clinicians, patients/care-givers, community-based health teams, and local policy makers to make timely and impactful improvements in injury prevention, clinical practice, and play structure safety.

Paediatric femoral fractures are a common result of significant trauma, and always require intervention. Hip spica casting, traction, and surgical fixation can all be used to treat these fractures. This variety in treatment options leads to a vast potential for variability in management decisions among surgeons and has prevented effective comparative studies to show which treatment methods provide optimal outcomes for patients. The purpose of this study was to identify practice variability in management and follow-up and assess patient outcomes to aid in the development of a comprehensive, prospective, evidence-based pathway for the management of paediatric femoral fractures.

A retrospective chart review was performed of all patients treated surgically for isolated femoral fractures during a six year period at a single tertiary care paediatric centre. Patients were identified from a surgical database and were included if there was no pre-existing pathology and no history of previous femoral fracture. Demographic data, operative details, post-operative management, and clinical outcomes were collected. Radiographic images and reports were analyzed to determine fracture classification and imaging parameters. Variability in treatment among eight surgeons was assessed, including number of follow-up appointments and length of follow-up. Patient demographics and follow up measures were summarised for each surgeon and between surgeon variability was assessed with linear models.

In total, 138 femoral fractures in 134 patients (101 male, 33 female) were included in analysis. Of these patients, 55 had right femoral fractures, 76 left, and three bilateral (one bilateral patient had three distinct femoral fractures). Of 138 total fractures, 131 were of the diaphysis of the femur. 14 patients sought initial surgical treatment at our institution but received follow-up management elsewhere. Across all patients, median follow-up time was 32.8 weeks (0–201.4) with a median of three follow-up visits (0–26) in that period. Mean number of follow-up clinic visits ranged from 3 to 4.8 among surgeons, and mean length of follow-up ranged from 31.8 to 62.3 weeks.

No significant differences in follow-up between surgeons were found, but small sample sizes are a likely contributing factor. Summary statistics show large ranges in most variables and differences in patient demographics between surgeon groups. The large ranges in follow-up time and visit number suggest a lack of consensus on optimal management for paediatric femoral fractures. Further prospective study examining long-term functional and quality of life outcomes will be required to identify and develop optimized management guidelines.

Fractures through the physis account for 18–30% of all paediatric fractures, leading to growth arrest in 5.5% of cases. We have limited knowledge to predict which physeal fractures result in growth arrest and subsequent deformity or limb length discrepancy. The purpose of this study is to identify factors associated with physeal growth arrest to improve patient outcomes.

This prospective cohort study was designed to develop a clinical prediction model for growth arrest after physeal injury. Patients < 1 8 years old presenting within four weeks of injury were enrolled if they had open physes and sustained a physeal fracture of the humerus, radius, ulna, femur, tibia or fibula. Patients with prior history of same-site fracture or a condition known to alter bone growth or healing were excluded. Demographic data, potential prognostic indicators and radiographic data were collected at baseline, one and two years post-injury.

A total of 167 patients had at least one year of follow-up. Average age at injury was 10.4 years, 95% CI [9.8,10.94]. Reduction was required in 51% of cases. Right-sided (52.5%) and distal (90.1%) fractures were most common. After initial reduction 52.5% of fractures had some form of residual angulation and/or displacement (38.5% had both). At one year follow-up, 34 patients (21.1%) had evidence of a bony bridge on plain radiograph, 10 (6.2%) had residual angulation (average 12.6°) and three had residual displacement. Initial angulation (average 22.4°) and displacement (average 5.8mm) were seen in 16/34 patients with bony bridge (48.5%), with 10 (30.3%) both angulated and displaced. Salter-Harris type II fractures were most common across all patients (70.4%) and in those with bony bridges (57.6%). At one year, 44 (27.3%) patients had evidence of closing/closed physes.

At one year follow-up, there was evidence of a bony bridge across the physis in 21.1% of patients on plain film, and residual angulation and/or displacement in 8.1%. Initial angulation and/or displacement was present in 64.7% of patients showing possible evidence of growth arrest. The incidence of growth arrest in this patient population appears higher than past literature reports. However, plain film is an unreliable modality for assessing physeal bars and the true incidence may be lower. A number of patients were approaching skeletal maturity at time of injury and any growth arrest is likely to have less clinical significance in these cases. Further prospective long-term follow-up is required to determine the true incidence and impact of growth arrest.

Supracondylar fractures of the humerus (SCH) are the most common fractures sustained following a fall on an outstretched hand in healthy children, and one of the leading causes of hospital admission and surgical intervention. With increasing severity of injury, treatment options become more invasive and the potential for long lasting complications increases. The aim of this study is to examine the causes and circumstances surrounding SCH in public play spaces particularly to determine whether or not the playground equipment implicated in injurious falls is compliant with Canadian Standards Association (CSA) standards.

Children aged 6–12 years who sustained SCH while playing at a public play space between 2017 and 2019 were recruited from the paediatric orthopaedic clinic. Public playgrounds within a 50 km radius of the clinic were visited by research assistants. Using GPS coordinates from photographs taken by the children at the site of injury or play structures identified by the children using Google Maps, play structure type, dimensions, height of fall, and the type and depth of the surface material were collected from each site and compared to the relevant CSA standard.

Of the 89 SCH injuries reported during the recruitment period, 49 (55%) occurred on public play structures. Thirty-nine injury sites, representing 42 SCH cases, were accessible to conduct site visits and were included in the analysis. Thirteen children (31%) sustained Type One, 19 (45%) were Type Two, and 10 (24%) were Type Three SCHs. The mean child age at injury was 7.13 years. Of the 42 SCH cases, 37 sites had woodchips surfacing (88%); three had rubber (7%), one had cement (2%), and one had sand (2%). Of the 36 sites where woodchip depth measurements could be obtained, only seven (19%) met the minimum CSA depth. Out of the 42 SCH cases, 29 injuries (69%) involved upper body equipment (i.e. monkey bars or similar) and track rides. Fourteen of these 29 injuries (48%) occurred on structures that did not meet CSA standards for fall height. All rotating play structures had less than half of the required clearance between the components.

Eighty-six percent of SCH cases occurred in playgrounds where at least one of the required CSA standards was not met. Woodchip surfacing was of particular concern because 81% of woodchip surface depths failed to meet CSA standards. Of the 14 injuries where fall height did not meet CSA standards, 11 (79%) also did not meet minimum CSA surface depth. Field investigation into the characteristics of playgrounds in which children sustain SCH can guide preventative policy and practice measures. Municipalities and school boards should be alerted to the need for regular maintenance of woodchip playground surfacing, in order to remain compliant with the minimum surface depth and prevent serious injuries. Additionally, compliance with minimum surface depths can also decrease fall heights to meet CSA standards. By minimizing the prevalence of SCH injuries occurring on play structures and the need for emergency department visits, the burden to healthcare systems and families of injured children can potentially be reduced.

Technology within medicine has great potential to bring about more accessible, efficient, and a higher quality delivery of care. Paediatric supracondylar fractures are the most common elbow fracture in children and at our institution often have high rates of unnecessary long term clinical follow-up, leading to an inefficient use of healthcare and patient resources. This study aims to evaluate patient and clinical factors that significantly predict necessity for further clinical visits following closed reduction and percutaneous pinning.

A total of 246 children who underwent closed reduction and percutaneous pinning following supracondylar humerus fractures were prospectively enrolled over a two year period. Patient demographics, perioperative course, goniometric measurements, functional outcome measures, clinical assessment and decision making for further follow up were assessed. Categorical and continuous variables were analyzed and screened for significance via bivariate regression. Significant covariates were used to develop a predictive model through multivariate logistical regression. A probability cut-off was determined on the Receiver Operator Characteristic (ROC) curve using the Youden index to maximize sensitivity and specificity. The regression model performance was then prospectively tested against 22 patients in a blind comparison to evaluate accuracy.

246 paediatrics patients were collected, with 29 cases requiring further follow up past the three month visit. Significant predictive factors for follow up were residual nerve palsy (p < 0 .001) and maximum active flexion angle of injured elbow (p < 0 .001). Insignificant factors included other goniometric measures, subjective evaluations, and functional outcomes scores. The probability of requiring further clinical follow up at the 3 month post-op point can be estimated with the equation: logit(follow-up) = 11.319 + 5.518(nerve palsy) − 0.108(maximum active flexion). Goodness of fit of the model was verified with Nagelkerke R2 = 0.574 and Hosmer & Lemeshow chi-square (p = 0.739). Area Under Curve of the ROC curve was C = 0.919 (SE = 0.035, 95% CI 0.850 – 0.988). Using Youden's Index, a cut-off for probability of follow up was set at 0.094 with the overall sensitivity and specificity maximized to 86.2% and 88% respectively. Using this model and cohort, 194 three month clinic visits would have been deemed medically unnecessary. Preliminary blind prospective testing against the 22 patient cohort demonstrates a model sensitivity and specificity at 100% and 75% respectively, correctly deeming 15 visits unnecessary.

Virtual clinics and automated clinical decision making can improve healthcare inefficiencies, unclog clinic wait times, and ultimately enhance quality of care delivery. Our regression model is highly accurate in determining medical necessity for physician examination at the three month visit following supracondylar fracture closed reduction and percutaneous pinning. When applied correctly, there is potential for significant reductions in health care expenditures and in the economic burden on patient families by removing unnecessary visits. In light of positive patient and family receptiveness toward technology, our promising findings and predictive model may pave the way for remote health care delivery, virtual clinics, and automated clinical decision making.

Paediatric supracondylar fractures are the most common elbow fracture in children, and is associated with an 11% incidence of neurologic injury. The goal of this study is to investigate the natural history and outcome of motor nerve recovery following closed reduction and percutaneous pinning of this injury.

A total of 246 children who underwent closed reduction and percutaneous pinning following supracondylar humerus fractures were prospectively enrolled over a two year period. Patient demographics (age, weight), Gartland fracture classification, and associated traumatic neurologic injury were collected and analyzed with descriptive statistics. Patients with neurologic palsies were separated based on nerve injury distribution, and followed long term to monitor for neurologic recovery at set time points for follow up.

Of the 246 patient cohort, 46 patients (18.6%) sustained a motor nerve palsy (Group 1) and 200 patients (82.4%) did not (Group 2) following elbow injury. Forty three cases involved one nerve palsy, and three cases involved two nerve palsies. No differences were found between patient age (Group 1 – 6.6 years old, Group 2 – 6.2 years old, p = 0.11) or weight (Group 1 – 24.3kg, Group 2 – 24.5kg, p = 0.44). A significantly higher proportion of Gartland type III and IV injuries were found in those with nerve palsies (Group 1 – 93.5%, Group 2 – 59%, p < 0 .001). Thirty four Anterior Interosseous Nerve (AIN) palsies were observed, of which 22 (64.7%) made a full recovery by three month. Refractory AIN injuries requiring longer than three month recovered on average 6.8 months post injury. Ten Posterior Interosseous Nerve (PIN) palsies occurred, of which four (40%) made full recovery at three month. Refractory PIN injuries requiring longer than three month recovered on average 8.4 months post injury. Six ulnar nerve motor palsies occurred, of which zero (0%) made full recovery at three month. Ulnar nerve injuries recovered on average 5.8 months post injury.

Neurologic injury occurs significantly higher in Gartland type III and IV paediatric supracondylar fractures. AIN palsies remain the most common, with an expected 65% chance of full recovery by three month. 40% of all PIN palsies are expected to fully recover by three month. Ulnar motor nerve palsies were slowest to recover at 0% by the three month mark, and had an average recovery time of approximately 5.8 months. Our study findings provide further evidence for setting clinical and parental expectations following neurologic injury in paediatric supracondylar elbow fractures.

Introduction

Trauma is the leading cause of death and disability in children. Pelvic fractures although rare, with a reported incidence of one per 100,000 children per year are 2^nd only to skull fractures with respect to morbidity. The objectives of this study were to improve understanding of paediatric pelvic fractures through a concise review of all aspects of these fractures and associated injuries. Understanding the patterns in which paediatric pelvic fractures and their associated injuries occur and the outcome of treatment is vital to the establishment of effective preventative, diagnostic and therapeutic interventions.

Odontoid synchondral fractures are considered the most common type of fracture, amounting TO 10% of all subaxial injuries in the under 7 demographic. This injury occurs as typically the result of hyperflexion. Most odontoid fractures in children below 7 years of age involves the odontoid synchondrosis

The following is a report of the management of paediatric synchondral fractures in 2 patients who presented to the Children's Hospital Westmead in 2010. Both patients had displaced synchondral odontoid fractures which were managed by indirect reduction and halo traction.

In both patients an anatomical alignment was achieved and maintained. Follow-up was 6 and 9 months respectively and the patients were assessed both clinically and radiologically.

We feel the use of the “double mattress” technique is a valuable tool, as a means of achieving and maintaining occipitocervical extension, necessary, in the treatment of odontoid synchondral fractures.

Introduction

Paediatric hip fracture accounts for less than one percent of paediatric fractures. Previous studies report complication rates between 20 and 92%.

We present a complete audit cycle of Emergency Department management of paediatric clavicle fractures at Derriford Hospital.

Local guidelines divide the clavicle into three zones. Fractures with minimal displacement in the middle 3/5th heal in the majority of cases without complication and can be discharged without need for follow up, provided parents are adequately educated.

An initial audit cycle of 63 cases identified short comings in adherence to the guidelines. These included: Unnecessary fracture clinic follow up of ‘Zone 2’ fractures in 85% and omission of written advice in 86%.

The results were circulated, ‘aide memoir’ icons were added to the department's computer coding system, staff teaching sessions were organised and a patient advice sheet was produced.

Following the implementation of changes, a 23 case re-audit showed fewer unnecessary referrals to fracture clinic (17% vs. 85%) and improvements in the number of parents being given written advice (43% vs. 14%).

Staff training, provision of information leaflets and changes to the ED coding system dramatically improved the adherence to hospital guidance.

This resulted in standardisation of care, fewer unnecessary appointments and cost savings to the trust. Following this audit, a telephone survey was completed to assess parent's satisfaction with their treatment.

Softcast is an attractive alternative to POP for unstable forearm fractures, providing a comfortable, water-resistant splint that can be removed without a plaster saw. Unreinforced Softcast has, however, only been recommended for buckle fractures. A laboratory study was undertaken to compare standardised POP, Softcast and reinforced Softcast splints at clinically relevant endpoints. The load at clinical failure of a 6-wrap Softcast forearm splint was 504N in bending, 202N in kinking, and 11Nm in torsion (equalling 30.4%, 26% and 42.2% of the equivalent values for a circumferential 4-wrap POP). Softcast was however stronger in all modes than a fibreglass-reinforced Softcast splint, such has been recommended for acute fractures. Furthermore, the load to failure in all modes exceeds that which can be exerted by body weight in many paediatric patients. Softcast demonstrated complete recovery of its original shape on unloading, and was 4% lighter than POP. A 6-wrap Softcast splint provides adequate mechanical stability and protection for paediatric patients up to 20kg, not engaged in high-risk activities. The primary risk is not of fracture angulation and loss of position, but temporary indentation of the splint, causing discomfort or pain. Considering its ease of removal, Softcast may be preferable for younger paediatric patients.

We present a complete audit cycle of Emergency Department (ED) management of paediatric buckle fractures of the distal radius at Derriford Hospital.

Local hospital management guidelines state that the limb should be supported in a wrist splint for 3 weeks following injury and, provided parents are adequately educated, no formal follow-up is required.

Auditable standards were obtained from the local guidance. An initial audit cycle of 54 cases identified shortcomings in compliance with guidelines. These included: Inappropriate immobilisation in 34 (63%) cases, omission of written advice in 35 (65%) cases and arrangement of unnecessary follow-up in 31 (57%) cases.

Following circulation of the results, ‘aide-memoir’ icons were added to the emergency department computer coding system, teaching sessions for emergency department staff were organised and new paediatric specific wrist splints were introduced.

A re-audit of 33 patients evaluated the effect of the changes. This demonstrated a 27% improvement in correct wrist support usage (27/33, 82%) and 25% fewer unnecessary referrals to fracture clinic (27/33, 82%).

Staff training and provision of appropriate wrist splints were crucial to improving the adherence to guidance. This resulted in standardisation of care, fewer unnecessary appointments for patients and cost savings to the hospital trust.

Introduction and aims

Cast immobilisation of paediatric forearm fractures has traditionally used plaster of Paris. Recently, synthetic casting materials have been used. There have been no studies comparing the efficacy of these two materials. The aim of this study is to investigate whether one material is superior for paediatric forearm fracture management.
