Summary Statement. Routine metal allergy screening prior to joint arthroplasty is not essential and the use of cobalt chromium or stainless steel implants is recommended regardless of the patient's metal allergy status. Introduction. This study was undertaken to obtain a consensus amongst joint arthroplasty experts with regards to metal allergy screening prior to joint arthroplasty and the choice of implant in patients with potential metal allergy. Patients & Methods. A web based Delphi consensus study was used including orthopaedic surgeons that had previously published on the topic of knee, hip or shoulder arthroplasty. Two rounds of questionnaires were sent via electronic mail. Consensus was considered if agreement was 60% or higher. Results. 18 surgeons responded to the first and 17 to the second round of questionnaires. There was consensus that patients having metal arthroplasty surgery should not be routinely questioned about metal allergy prior to surgery. There was consensus that patch testing is not necessary even if metal allergy is suspected. Most respondents agreed in proceeding with cobalt chromium or stainless steel implant in patients suspected of metal allergy regardless of the results of cutaneous patch testing. Discussion/Conclusion. This consensus study suggests that routine metal allergy screening prior to joint arthroplasty is not essential. The use of traditional cobalt chromium/stainless steel implants is recommended regardless of the patient's metal allergy status

The aim of this study was to perform a systematic review of the literature on Gustilo-Anderson (GA) type IIIB open tibial shaft (AO-42) injuries to determine the consistency of reporting in the literature. A search of PubMed, EMBASE and Cochrane Central Register of Controlled Trials was performed to identify relevant studies published from January 2000 to January 2021 using the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) statement. The study was registered using the PROSPERO International prospective register of systematic reviews. Patient/injury demographics, management and outcome reporting were recorded. There were 32 studies that met the inclusion criteria with a total of 1,947 patients (70.3% male, 29.7% female). There were 6 studies (18.8%) studies that reported on comorbidities and smoking, with mechanism of injury reported in 22 (68.8%). No studies reported on all operative criteria included, with only three studies (9.4%) reporting for time to antibiotics, 14 studies (43.8%) for time from injury to debridement and nine studies (28.1%) for time to definitive fixation. All studies reported on the rate of deep infection, with a high proportion documenting union rate (26/32, 81.3%). However, only two studies reported on mortality or on other post-operative complications (2/32, 6.3%). Only 12 studies (37.5%) provided any patient reported outcomes. This study has demonstrated a deficiency and a lack of standardized variable and outcome reporting in the orthopaedic literature for Gustilo-Anderson type IIIB open tibial shaft fractures. We propose a future international collaborative Delphi process is needed to standardize

Neurological complications in oncological and degenerative spine surgery represent one of the most feared risks of these procedures. Multimodal intraoperative neurophysiological monitoring (IONM) mainly uses methods to detect changes in the patient's neurological status in a timely manner, thus allowing actions that can reverse neurological deficits before they become irreversible. The utopian goal of spinal surgery is the absence of neurological complications while the realistic goal is to optimize the responses to changes in neuromonitoring such that permanent deficits occur less frequently as possible. In 2014, an algorithm was proposed in response to changes in neuromonitoring for deformity corrections in spinal surgery. There are several studies that confirm the positive impact that a checklist has on care. The proposed checklist has been specifically designed for interventions on stable columns which is significantly different from oncological and degenerative surgery. The goal of this project is to provide a checklist for oncological and degenerative spine surgery to improve the quality of care and minimize the risk of neurological deficit through the optimization of clinical decision-making during periods of intraoperative stress or uncertainty. After a literature review on risk factors and recommendations for responding to IONM changes, 3 surveys were administered to 8 surgeons with experience in oncological and degenerative spine surgery from 5 hospitals in Italy. In addition, anesthesiologists, intraoperative neuro-monitoring teams, operating room nurses participated. The members participated in the optimization and final drafting of the checklist. The authors reassessed and modified the checklist during 3 meetings over 9 months, including a clinical validation period using a modified Delphi process. A checklist containing 28 items to be considered in responding to the changes of the IONM was created. The checklist was submitted for inclusion in the new recommendations of the Italian Society of Clinical Neurophysiology (SINC) for intraoperative neurophysiological monitoring. The final checklist represents the consensus of a group of experienced spine surgeons. The checklist includes the most important and high-performance items to consider when responding to IONM changes in patients with an unstable spine. The implementation of this checklist has the potential to improve surgical outcomes and patient safety in the field of spinal surgery

An international Consensus Group has by a Delphi approach identified the topic of host factors affecting pin site infection to be one of the top 10 priorities in external fixator management. The aim of this study was to report the frequency of studies reporting on specific host factors as a significant association with pin site infection. Host factors to be assessed was: age, smoking, BMI and any comorbidity, diabetes, in particular. The intention was an ethological review, data was extracted if feasible, however no meta-analysis was performed. A systematic literature search was performed according to the PRISMA-guidelines. The protocol was registered before data extraction in PROSPERO. The search string was based on the PICO criterias. A logic grid with key concept and index terms was made. A search string was built assisted by a librarian. The literature search was executed in three electronic bibliographic databases, including Embase MEDLINE (1111 hits) and CINAHL (2066 hits) via Ovid and Cochrane Library CENTRAL (387 hits). Inclusion criteria: external fixation, >1 pin site infection, host factor of interest, peer-reviewed journal. Exclusion criteria: Not written in English, German, Danish, Swedish, or Norwegian, animal or cadaveric studies, location on head, neck, spine, cranium or thorax, editorials or conference abstract. The screening process was done using Covidence. A total of 3564 titles found. 3162 excluded by title and abstract screening. 140 assessed for full text eligibility. 11 studies included for data extraction. The included studies all had a retrospective design. Three identified as case-control studies. Generally the included studies was assessed to have a high risk of bias. A significant associations between pin site infection for following host factors: a) increased HbA1C level in diabetic patients; b) congestive heart failure in diabetic patients; c) less co-morbidity; d) preoperative osteomyelitis was found individually. This systematic literature search identified a surprisingly low number of studies examining for risk of pin site infection and host factors. Thus, this review most of all serves to demonstrate a gap of evidence about correlation between host factors and risk of pin site infection, and further studies are warranted

Axial musculoskeletal control (AMC) is a widely used concept and has been shown to be an important factor in physical performance, the pathophysiology of back pain and other MSK conditions. However, there is no agreement on a definition of AMC, nor a validated test for AMC and its application in clinical practice. Our aim was to develop a test for AMC using the Delphi method from a panel of experts with video and analysis of the footage. We found that the most commonly used tests were the maintenance of neutral pelvic position in single leg stance, single leg stance with eyes closed and single leg squat. We aim to further validate our findings by comparing this to surface EMG recordings and centre of gravity measurements in stress situations

Aims. 1. To develop a decision aid - Decision Support Package (DSP) - that will provide low back pain (LBP) patients, and their treating physiotherapists with information on the treatment options available to the patients. 2. To develop a training package for physiotherapists on how to use the DSP. 3. To encourage and evaluate the informed shared decision making (ISDM) process between patients and physiotherapists during consultation. Method. We developed a DSP informed by existing research and collaboration with physiotherapists, patients and experts in the field of decision aids and LBP. We did six pieces of exploratory work: literature review; 2009 NICE LBP guidelines review; qualitative screening of transcripts of interviews of LBP patients; focus groups (patients); nominal group (physiotherapists), and Delphi study (experts). We collated these data to develop the DSP. We also developed a training package for physiotherapists. Results. We developed a LBP patient resource for use prior to their first consultation and a training package for physiotherapists. The DSP contained information on acupuncture, structured group exercise, manual therapy and cognitive behavioural approach. LBP patients would expect these treatment options to be offered to them at their initial consultation. The training package for physiotherapists was on DSP use and communication skills during consultation. Conclusion. We have developed an evidence and theory informed Decision Support Package and physiotherapists training. We are currently piloting its use in one NHS Trust prior to running a pilot RCT (N=150) to test is effect on improving patient satisfaction with LBP patients' treatment choices.

Objectives

The patient-rated wrist evaluation (PRWE) and the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire are patient-reported outcome measures (PROMs) used for clinical and research purposes. Methodological high-quality clinimetric studies that determine the measurement properties of these PROMs when used in patients with a distal radial fracture are lacking. This study aimed to validate the PRWE and DASH in Dutch patients with a displaced distal radial fracture (DRF).

Objectives

We aimed first to summarise minimal clinically important differences (MCIDs) after total hip (THR) or knee replacement (TKR) in health-related quality of life (HRQoL), measured using the Short-Form 36 (SF-36). Secondly, we aimed to improve the precision of MCID estimates by means of meta-analysis.

The aim of this study was to validate the use of three models of fracture fixation in the assessment of technical skills. We recruited 21 subjects (six experts, seven intermediates, and eight novices) to perform three procedures: application of a dynamic compression plate on a cadaver porcine model, insertion of an unreamed tibial intramedullary nail, and application of a forearm external fixator, both on synthetic bone models. The primary outcome measures were the Objective Structural Assessment of technical skills global rating scale on video recordings of the procedures which were scored by two independent expert observers, and the hand movements of the surgeons which were analysed using the Imperial College Surgical Assessment Device.

The video scores were significantly different for the three groups in all three procedures (p < 0.05), with excellent inter-rater reliability (α = 0.88). The novice and intermediate groups specifically were significantly different in their performance with dynamic compression plate and intramedullary nails (p < 0.05). Movement analysis distinguished between the three groups in the dynamic compression plate model, but a ceiling effect was demonstrated in the intramedullary nail and external fixator procedures, where intermediates and experts performed to comparable standards (p > 0.6). A total of 85% (18 of 21) of the subjects found the dynamic compression model and 57% (12 of 21) found all the models acceptable tools of assessment.

This study has validated a low-cost, high-fidelity porcine dynamic compression plate model using video rating scores for skills assessment and movement analysis. It has also demonstrated that Synbone models for the application of and intramedullary nail and an external fixator are less sensitive and should be improved for further assessment of surgical skills in trauma. The availability of valid objective tools of assessment of surgical skills allows further studies into improving methods of training.
