IntroductionAs patient-reported outcome measures (PROMs) have become of significant importance in evaluation of care and clinical research, adequately selecting the appropriate instrument is an integral part of paediatric orthopaedic research and clinical practice. This systematic review aims to provide a comprehensive overview of PROMs targeted at children with impairment of the lower limb, and to critically appraise and summarise the quality of their measurement properties by applying the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) methodology.Method and analysisA systematic search of the MEDLINE and EMBASE databases will be performed to identify relevant publications reporting on the development and/or validation of PROMs used for evaluating children with impairment of the lower extremity. Data extraction and quality assessment of the included studies will be undertaken by two reviewers independently and in accordance with COSMIN guidelines.Ethics and disseminationIt is not necessary to obtain ethical approval for this systematic review. The results will be published in a peer-reviewed journal and will be presented at relevant conferences to enhance information dissemination.PROSPERO registration numberCRD42021287323.

Background As patient-reported outcome measures (PROMs) have become of significant importance in patient evaluation, adequately selecting the appropriate instrument is an integral part of pediatric orthopedic research and clinical practice. This systematic review provides a comprehensive overview of PROMs targeted at children with impairment of the upper limb, and critically appraises and summarizes the quality of their measurement properties by applying the COnsensus-based Standards for selection of health Measurement INstruments (COSMIN) methodology. Methods A systematic search of the MEDLINE and EMBASE databases was performed to identify relevant publications reporting on the development and/or validation of PROMs used for evaluating children with impairment of the upper extremity. Data extraction and quality assessment (including a risk of bias evaluation) of the included studies was undertaken by two reviewers independently and in accordance with COSMIN guidelines. Results Out of 6423 screened publications, 32 original articles were eligible for inclusion in this review, reporting evidence on the measurement properties of 22 self- and/or proxy-reported questionnaires (including seven cultural adaptations) for various pediatric orthopedic conditions, including cerebral palsy (CP) and obstetric brachial plexus palsy (OBPP). The measurement property most frequently evaluated was construct validity. No studies evaluating content validity and only four PROM development studies were included. The methodological quality of these development studies was either ‘doubtful’ or ‘inadequate’. The quantity and quality of the evidence on the other measurement properties of the included questionnaires varied substantially with insufficient sample sizes and/or poor methodological quality resulting in significant downgrading of evidence quality. Conclusion This review provides a comprehensive overview of currently available PROMs for evaluation of the pediatric upper limb. Based on our findings, none of the PROMs demonstrated sufficient evidence on their measurement properties to justify recommending the use of these instruments. These findings provide room for validation studies on existing pediatric orthopedic upper limb PROMs (especially on content validity), and/or the development of new instruments.

Lateral humeral condyle fractures are frequently seen in pediatric patients and have a high risk of unfavorable outcomes. A fall on the outstretched arm with supination of the forearm is the most common trauma mechanism. A physical examination combined with additional imaging will confirm the diagnosis. Several classifications have been described to categorize these fractures based on location and comminution. Treatment options depend on the severity of the fracture and consist of immobilization in a cast, closed reduction with percutaneous fixation, and open reduction with fixation. These fractures can lead to notable complications such as lateral condyle overgrowth, surgical site infection, pin tract infections, stiffness resulting in decreased range of motion, cubitus valgus deformities, ‘fishtail’ deformities, malunion, non-union, avascular necrosis, and premature epiphyseal fusion. Adequate follow-up is therefore warranted.

BackgroundTraumatic elbow injuries in children occur frequently and are among the most common traumatic injuries seen in the emergency department (ED) and in general practice. The use of a validated decision rule to enhance selective radiography in paediatric patients with possible elbow fractures may reduce unnecessary exposure to radiation in children.Method and analysisThis study is designed as a multicentre prospective cohort study. An expert panel of orthopaedic elbow surgeons, paediatric orthopaedic surgeons and trauma surgeons will initially determine clinical parameters that provide a possible predictive value for elbow fractures. Four hundred children between the ages of 2 and 17 years visiting the ED with pain following elbow trauma will then be included. The clinical parameters will be collected via patient history and physical examination. Elbow radiographs will be obtained in all patients to identify fractures. The data will be processed in a multivariable logistic regression analysis to determine which clinical parameters predict the presence of an elbow fracture. Only the clinical parameters that predict a fracture will be used to formulate the new decision rule: the paediatric elbow trauma (PET) rules. Internal validation of the prediction model will take place after inclusion is complete and by means of a bootstrap analysis on the acquired data. A calculation will be made to determine how many radiographs can potentially be reduced by applying the PET rules and a cost analysis will be performed.Ethics and disseminationThe study will be conducted according to the principles of the Declaration of Helsinki and in accordance with the Medical Research Involving Human Subjects Act. The Medical Research Ethics Committees United stated on 16 May 2022 that The Medical Research Involving Human Act (WMO) does not apply to this study and an official approval by the committee is not required, reference number; project W22.086.
