Aims. The aim of this modified Delphi process was to create a structured Revision Hip Complexity Classification (RHCC) which can be used as a tool to help direct multidisciplinary team (MDT) discussions of complex cases in local or regional revision networks. Methods. The RHCC was developed with the help of a steering group and an invitation through the British Hip Society (BHS) to members to apply, forming an expert panel of 35. We ran a mixed-method modified Delphi process (three rounds of questionnaires and one virtual meeting). Round 1 consisted of identifying the factors that govern the decision-making and complexities, with weighting given to factors considered most important by experts. Participants were asked to identify classification systems where relevant. Rounds 2 and 3 focused on grouping each factor into H1, H2, or H3, creating a hierarchy of complexity. This was followed by a virtual meeting in an attempt to achieve consensus on the factors which had not achieved consensus in preceding rounds. Results. The expert group achieved strong consensus in 32 out of 36 factors following the Delphi process. The RHCC used the existing Paprosky (acetabulum and femur), Unified Classification System, and American Society of Anesthesiologists (ASA) classification systems. Patients with ASA grade III/IV are recognized with a qualifier of an asterisk added to the final classification. The classification has good intraobserver and interobserver reliability with Kappa values of 0.88 to 0.92 and 0.77 to 0.85, respectively. Conclusion. The RHCC has been developed through a modified Delphi technique. RHCC will provide a framework to allow discussion of complex cases as part of a local or regional hip revision MDT. We believe that adoption of the RHCC will provide a comprehensive and reproducible method to describe each patient’s case with regard to surgical complexity, in addition to medical comorbidities that may influence their management.

Abstract. Introduction. Knee dislocations (KDs) are complex injuries which are often associated with damage to surrounding soft tissues or neurovascular structures. A classification system for these injuries should be simple and reproducible and allow communication among surgeons for surgical planning and outcome prediction. The aim of this study was to formulate a list of factors, prioritised by high-volume knee surgeons, that should be included in a KD classification system. Methods. A global panel of orthopaedic knee surgery specialists participated in a Delphi process. A list of factors to be included in a KD classification system was formulated by 91 orthopaedic surgeons, which was subsequently prioritised by 27 experts from 6 countries. The items were analysed to find factors that had at least 70% consensus for inclusion in a classification system. Results. The four factors that reached consensus agreement and thus deemed critical for inclusion in a classification system were vascular injuries (89%), common peroneal nerve injuries (78%), number of torn ligaments (78%), and open injuries (70%). Conclusion. The wide geographic distribution of participants provides diverse insight and makes the results of the study globally applicable. The most important factors to include in a classification system as determined by the Delphi technique were vascular injuries, common peroneal nerve injuries, number of torn ligaments, and open injuries. The Schenck anatomic classification system most accurately identifies these patient variables with the addition of open injuries. The authors propose to update the Schenck classification system with the inclusion of open injuries as an additional modifier

Musculoskeletal (MSK) injuries are one of the leading causes of disability worldwide. Despite improvements in trauma-related morbidity and mortality in high-income countries over recent years, outcomes following MSK injuries in low and middle-income countries, such as South Africa (SA), have not. Despite governmental recognition that this is required, funding and research into this significant health burden are limited within SA. This study aims to identify research priorities within MSK trauma care using a consensus-based approach amongst MSK health care practitioners within SA. Members from the Orthopaedic Research Collaborative (ORCA), based in SA, collaborated using a two round modified Delphi technique to form a consensus on research priorities within orthopaedic trauma care. Members involved in the process were orthopaedic healthcare practitioners within SA. Participants from the ORCA network, working within SA, scored research priorities across two Delphi rounds from low to high priority. We have published the overall top 10 research priorities for this Delphi process. Questions were focused on two broad groups - clinical effectiveness in trauma care and general trauma public health care. Both groups were represented by the top two priorities, with the highest ranked question regarding the overall impact of trauma in SA and the second regarding the clinical treatment of open fractures. This study has defined research priorities within orthopaedic trauma in South Africa. Our vision is that by establishing consensus on these research priorities, policy and research funding will be directed into these areas. This should ultimately improve musculoskeletal trauma care across South Africa and its significant health and socioeconomic impacts

Acute spinal cord injury (SCI) is most often secondary to trauma, and frequently presents with associated injuries. A neurological examination is routinely performed during trauma assessment, including through Advanced Trauma Life Support (ATLS). However, there is no standard neurological assessment tool specifically used for trauma patients to detect and characterize SCI during the initial evaluation. The International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI) is the most comprehensive and popular tool for assessing SCI, but it is not adapted to the acute trauma patients such that it is not routinely used in that setting. Therefore, the objective is to develop a new tool that can be used routinely in the initial evaluation of trauma patients to detect and characterize acute SCI, while preserving basic principles of the ISNCSCI. The completion rate of the ISCNSCI during the initial evaluation after an acute traumatic SCI was first estimated. Using a modified Delphi technique, we designed the Montreal Acute Classification of Spinal Cord Injuries (MAC-SCI), a new tool to detect and characterize the completeness (grade) and level of SCI in the polytrauma patient. The ability of the MAC-SCI to detect and characterize SCI was validated in a cohort of 35 individuals who have sustained an acute traumatic SCI. The completeness and neurological level of injury (NLI) were assessed by two independent assessors using the MAC-SCI, and compared to those obtained with the ISNCSCI. Only 33% of patients admitted after an acute traumatic SCI had a complete ISNCSCI performed at initial presentation. The MAC-SCI includes 53 of the 134 original elements of the ISNCSCI which is 60% less. There was a 100% concordance between the severity grade derived from the MAC-SCI and from the ISNCSCI. Concordance of the NLI within two levels of that obtained from the ISNCSCI was observed in 100% of patients with the MAC-SCI and within one level in 91% of patients. The ability of the MAC-SCI to discriminate between cervical (C0 to C7) vs. thoracic (T1 to T9) vs. thoraco-lumbar (T10 to L2) vs. lumbosacral (L3 to S5) injuries was 100% with respect to the ISNCSCI. The rate of completion of the ISNCSCI is low at initial presentation after an acute traumatic SCI. The MAC-SCI is a streamlined tool proposed to detect and characterize acute SCI in polytrauma patients, that is specifically adapted to the acute trauma setting. It is accurate for determining the completeness of the SCI and localize the NLI (cervical vs. thoracic vs. lumbar). It could be implemented in the initial trauma assessment protocol to guide the acute management of SCI patients

Aim. To develop a clinical core set of outcome measures that is accepted for relevance, feasibility and validity by stakeholders and useful for a) interaction between patient and professional, b) internal quality improvement, and c) external transparency in patients with NSLBP in primary care physical therapy. Method. We used a consensus-driven modified RAND-UCLA Delphi technique. We conducted seven separate steps with panellists (physical therapists, patient representatives, health insurers) to select accepted outcomes. These seven steps consisted of a literature search, two online surveys, patient interviews, an experts meeting, a consensus meeting and final approval of an advisory board. Results of previous steps were discussed during the consensus meeting, and then panellists voted for inclusion per measure. The final core set was rated on relevance and feasibility on a 9-point Likert scale, when the median was ≥7 the core set was accepted. Results. 34 panellists in two online surveys, five panellists in an expert committee, ten patients for semi-structured interviews and 26 panellists in a consensus meeting participated in the study. 12 outcome measures were rated and discussed and finally six outcome measures were accepted. The final core set was accepted with a median of 7. Conclusion. This study present an outcome set that is accepted by stakeholders as having added value for a) interaction between patient and professional, b) internal quality improvement, and c) external transparency in patients with NSLBP in primary care physical therapy. In a next project this outcome set will be tested on his reliability and feasibility in a large pilot. No conflicts of interest. Sources of funding: Health insurance company CZ, the Netherlands

Aims. High-quality clinical research in children’s orthopaedic surgery has lagged behind other surgical subspecialties. This study used a consensus-based approach to identify research priorities for clinical trials in children’s orthopaedics. Methods. A modified Delphi technique was used, which involved an initial scoping survey, a two-round Delphi process and an expert panel formed of members of the British Society of Children’s Orthopaedic Surgery. The survey was conducted amongst orthopaedic surgeons treating children in the United Kingdom and Ireland. Results. A total of 86 clinicians contributed to both rounds of the Delphi process, scoring priorities from one (low priority) to five (high priority). Elective topics were ranked higher than those relating to trauma, with the top ten elective research questions scoring higher than the top question for trauma. Ten elective, and five trauma research priorities were identified, with the three highest ranked questions relating to the treatment of slipped capital femoral epiphysis (mean score 4.6/ 5), Perthes’ disease (4.5) and bone infection (4.5). Conclusion. This consensus-based research agenda will guide surgeons, academics and funders to improve the evidence in children’s orthopaedic surgery and encourage the development of multicentre clinical trials.

Aims. This study aimed to develop a virtual clinic for the purpose of reducing face-to-face orthopaedic consultations. Patients and Methods. Anonymized experts (hip and knee arthroplasty patients, surgeons, physiotherapists, radiologists, and arthroplasty practitioners) gave feedback via a Delphi Consensus Technique. This consisted of an iterative sequence of online surveys, during which virtual documents, made up of a patient-reported questionnaire, standardized radiology report, and decision-guiding algorithm, were modified until consensus was achieved. We tested the patient-reported questionnaire on seven patients in orthopaedic clinics using a ‘think-aloud’ process to capture difficulties with its completion. Results. A patient-reported 13-item questionnaire was developed covering pain, mobility, and activity. The radiology report included up to ten items (e.g. progressive periprosthetic bone loss) depending on the type of arthroplasty. The algorithm concludes in one of three outcomes: review at surgeon’s discretion (three to 12 months); see at next available clinic; or long-term follow-up/discharge. Conclusion. The virtual clinic approach with attendant documents achieved consensus by orthopaedic experts, radiologists, and patients. The robust development and testing of this standardized virtual clinic provided a sound platform for organizations in the United Kingdom to adopt a virtual clinic approach for follow-up of hip and knee arthroplasty patients.

Introduction Non-specific low back pain (NSLBP) is an extremely heterogeneous condition with many attempts at sub-classification having been made over the years. Background and Purpose of the Study This study developed UK physiotherapy, professional consensus on the items to be included in a list of important “discriminatory” examination features. These features will be subsequently tested in a large cluster analysis with a view to generating a valid sub-classification of NSLBP. Material and Method Thirty UK Chartered Physiotherapists, representatives from Clinical Interest Groups, attended a focus group and subsequently undertook a Delphi consensus technique. Participants were purposively sampled from all clinical interest groups to represent as broad a clinical experience as possible. The focus group established the areas of the examination that were to be included in the Delphi process. The Delphi consensus process involved an initial round of statement generation. The physiotherapists were asked to list the examination items, from the history and physical examinations that they rated as important discriminators of different “types” of NSLBP. A content analysis was undertaken to establish common features within the statements and the examination features were then rated for inclusion in the list. A priori, consensus was considered to have been gained when > 80% of participants agreed on inclusion of an examination feature and following a third round of rating consensus was achieved. Results Eighty examination items were included in the list by participants, following three rounds of the Delphi technique. Fifty items were from the history and thirty items from the physical examination. Items included were from the biomedical, psychological and social domains. Conclusion This study provides valuable insight into the items of the clinical examination considered important in the discrimination of sub-groups of NSLBP by UK physiotherapists

Introduction. Because of the low cost and easy access, surgical video has become a popular method of acquiring surgical skills outside operating rooms without disrupting normal surgical flow. However, currently existing video systems all use a single point of view (POV). Some complex orthopedic procedures, such as joint replacement, require a level of accuracy in several dimensions. So single and fixed POV video may not be enough to provide all the necessary information for educational and training purposes. The aim of our project was to develop a novel multiple POV video system and evaluate its efficacy as an aid for learning joint replacement procedure compared with traditional method. Materials and Methods. Based on the videos of a hip resurfacing procedure performed by an expert orthopedic surgeon captured by 8 cameras fixed all around the operating table, we developed a novel multiple POV video system which enables users to autonomously switch between optimal viewpoints (Figure 1). 30 student doctors (undergraduate years 3–5 and naive to hip resurfacing procedure) were recruited and randomly allocated to 2 groups: experiment group and control group, and were assigned to learn the procedure using multiple or single POV video systems respectively. Before learning they were first asked to complete a multiple choicetest designed using a modified Delphi technique with the advice and feedback sought from 4 experienced orthopedic surgeons to test the participants' baseline knowledge of hip resurfacing procedure. After video learning, they were asked to answer the test again to verify their gained information and comprehension of the procedure, followed by a 5-point Likert-scale questionnaire to demonstrate their self-perception of confidence and satisfaction with the learning experience. The scores in the 2 tests and in the Likert-scale questionnaire were compared between 2 groups using Independent-Samples t-test (for normally distributed data) or Mann-Whitney U test (for non-normally distributed data). Statistical significance was set as p<0.05. Results. There was no significant difference regarding the ages of the participants between the experiment group (22.27 ± 1.79 years) and the control group (23.00 ± 1.56 years) (p value=0.242). The 10 questions in the test were divided into 3 subcategories: 4 questions regarding spatial awareness, 4 regarding operation details and 2 regarding sequence comprehension. There was no significant difference between both cohorts in the baseline test scores (for overall scores or scores in any subcategory) before video-learning, thus ensuring homogeneity. Yet, there was a 31.6–75.4% significantly (p<0.033) higher test score after video learning in the experiment group compared with the control group (for overall, spatial awareness and operation details scores) (Figure 2). The mean Likert-scale questionnaire score in the experiment group was also 32% significantly greater than the control group (Figure 3). Conclusion. Trainees could gain better knowledge and comprehension of hip resurfacing procedure and show higher confidence and satisfaction after learning using the novel multiple POV video system compared with traditional single POV video. The novel system could serve as an effective tool for teaching hip resurfacing procedure before trainees proceed to the real operating room. For figures, please contact authors directly

Introduction: A large number of patients with non-specific low back pain (NSLBP) are examined by physiotherapists. Physiotherapists ask their patient’s questions, as part of their clinical examination, however the reliability of the information elicited by these questions has never been examined. Methods: Following a Focus group with a sample of physiotherapists (n=30), and subsequent Delphi technique questionnaire, a list of questions and tests for the clinical examination to NSLBP was developed. The clinical examination list was then tested for item inter-tester reliability with 100 NSLBP patients and 16 physiotherapists. Patients were assessed by both physiotherapists on one day. Data were analysed using kappa coefficients for nominal data and weighted kappas for ordinal data. Results: The physiotherapists rated issues regarding the location and quality of pain with good levels of reliability, kappa values ranged from 0.49 to 0.64. Diurnal changes in pain and history of pain were also reliably ascertained (Kappa values ranging from 0.49 to 0.73), with symptoms other than pain demonstrating good reliability (values ranging from 0.50 to 0.77). Issues regarding the affect of psychosocial issues as barriers to recovery and the degree to which the patient’s pain was affecting their function were not as reliable (kappa values from 0.14 to 0.51). Conclusions: It is clear that whilst the questions typically used in the clinical examination of NSLBP are reliable when addressing simple issues relating to the report of symptoms, more complex issues are less reliable and further work is required to improve the reliability of the information obtained
