Artificial Intelligence (AI) is becoming more powerful but is barely used to counter the growth in health care burden. AI applications to increase efficiency in orthopedics are rare. We questioned if (1) we could train machine learning (ML) algorithms, based on answers from digitalized history taking questionnaires, to predict treatment of hip osteoartritis (either conservative or surgical); (2) such an algorithm could streamline clinical consultation. Multiple ML models were trained on 600 annotated (80% training, 20% test) digital history taking questionnaires, acquired before consultation. Best performing models, based on balanced accuracy and optimized automated hyperparameter tuning, were build into our daily clinical orthopedic practice. Fifty patients with hip complaints (>45 years) were prospectively predicted and planned (partly blinded, partly unblinded) for consultation with the physician assistant (conservative) or orthopedic surgeon (operative). Tailored patient information based on the prediction was automatically sent to a smartphone app. Level of evidence: IV. Random Forest and BernoulliNB were the most accurate ML models (0.75 balanced accuracy). Treatment prediction was correct in 45 out of 50 consultations (90%), p<0.0001 (sign and binomial test). Specialized consultations where conservatively predicted patients were seen by the physician assistant and surgical patients by the orthopedic surgeon were highly appreciated and effective. Treatment strategy of hip osteoartritis based on answers from digital history taking questionnaires was accurately predicted before patients entered the hospital. This can make outpatient consultation scheduling more efficient and tailor pre-consultation patient education

In the field of hand surgery, physicians are working to improve patient satisfaction by offering several minor procedures in the physician's office via the WALANT method. We seek to investigate the degree of patient satisfaction, out of pocket cost, convenience and comfort experienced with in-office hand procedures. A ten question survey consisting of a ten-point Likert scale of agreement and questions asking for a numerical answer was administered via phone call to 33 patients treated with minor hand operations in the office setting in the United States. There were 18 male and 15 female respondents with an average age of 65.59±12.64 years. Respondents underwent procedures including trigger finger release (18), needle aponeurotomy (7), and other minor hand operations. Survey responses indicated strong agreement with questions 1-3 and 6–8, with responses averaging 9.60±0.23 in these positive metrics. Questions 4 and 5, which asked whether the surgery and recovery period were painful, respectively, averaged 2.65±0.49, indicating a mild level of disagreement that either was “painful”. Additionally, most patients responded that they did not take time off work (12) or are not currently employed (11). Other respondents (3) reported taking between one to five days off work post-operatively. 27 respondents also reported an out of pocket cost averaging $382±$976, depending on insurance coverage. Patients reported a small degree of pain in the operative and post-operative period, a high degree of comfort and convenience and a high degree of satisfaction. Likewise, the patient-reported out of pocket cost was far lower than comparable surgical costs in alternate settings. These results support the use of in-office procedures for minor hand surgeries from a patient perspective and indicate a nearly universal intent to repeat any future hand operations in the office setting

Among the advanced technology developed and tested for orthopaedic surgery, the Rizzoli (IOR) has a long experience on custom-made design and implant of devices for joint and bone replacements. This follows the recent advancements in additive manufacturing, which now allows to obtain products also in metal alloy by deposition of material layer-by-layer according to a digital model. The process starts from medical image, goes through anatomical modelling, prosthesis design, prototyping, and final production in 3D printers and in case post-production. These devices have demonstrated already to be accurate enough to address properly the specific needs and conditions of the patient and of his/her physician. These guarantee also minimum removal of the tissues, partial replacements, no size related issues, minimal invasiveness, limited instrumentation. The thorough preparation of the treatment results also in a considerable shortening of the surgical and of recovery time. The necessary additional efforts and costs of custom-made implants seem to be well balanced by these advantages and savings, which shall include the lower failures and revision surgery rates. This also allows thoughtful optimization of the component-to-bone interfaces, by advanced lattice structures, with topologies mimicking the trabecular bone, possibly to promote osteointegration and to prevent infection. IOR's experience comprises all sub-disciplines and anatomical areas, here mentioned in historical order. Originally, several systems of Patient-Specific instrumentation have been exploited in total knee and total ankle replacements. A few massive osteoarticular reconstructions in the shank and foot for severe bone fractures were performed, starting from mirroring the contralateral area. Something very similar was performed also for pelvic surgery in the Oncology department, where massive skeletal reconstructions for bone tumours are necessary. To this aim, in addition to the standard anatomical modelling, prosthesis design, technical/technological refinements, and manufacturing, surgical guides for the correct execution of the osteotomies are also designed and 3D printed. Another original experience is about en-block replacement of vertebral bodies for severe bone loss, in particular for tumours. In this project, technological and biological aspects have also been addressed, to enhance osteointegration and to diminish the risk of infection. In our series there is also a case of successful custom reconstruction of the anterior chest wall. Initial experiences are in progress also for shoulder and elbow surgery, in particular for pre-op planning and surgical guide design in complex re-alignment osteotomies for severe bone deformities. Also in complex flat-foot deformities, in preparation of surgical corrections, 3D digital reconstruction and 3D printing in cheap ABS filaments have been valuable, for indication, planning of surgery and patient communication; with special materials mimicking bone strength, these 3D physical models are precious also for training and preparation of the surgery. In Paediatric surgery severe multi planar & multifocal deformities in children are addressed with personalized pre-op planning and custom cutting-guides for the necessary osteotomies, most of which require custom allografts. A number of complex hip revision surgeries have been performed, where 3D reconstruction for possible final solutions with exact implants on the remaining bone were developed. Elective surgery has been addressed as well, in particular the customization of an original total ankle replacement designed at IOR. Also a novel system with a high-tibial-osteotomy, including a custom cutting jig and the fixation plate was tested. An initial experience for the design and test of custom ankle & foot orthotics is also in progress, starting with 3D surface scanning of the shank and foot including the plantar aspect. Clearly, for achieving these results, multi-disciplinary teams have been formed, including physicians, radiologists, bioengineers and technologists, working together for the same goal

The primary purpose of this longitudinal study was to examine the impact of physical and mental well-being on a successful return to work after cartilage or ligament knee injury. A secondary purpose was to examine the effectiveness of our program regarding ordering imaging (plain X-rays, US, MRI, CT scan), and the impact that costly investigations made in clinical management. Workers who had sustained a work-related knee injury and were assessed at the lower extremity specialty clinic of our hospital program were followed up until they were discharged. All patients completed the numeric pain rating scale (NPRS), the Lower Extremity Functional Scale (LEFS), and the Hospital Anxiety and Depression Scale (HADS) on the initial assessment and at final follow-up. We included 30 patients, mean age, 50(9), 11(37%) females, 19(63%) males. The most common mechanisms of injury were twisting (13, 45%) and falls (12, 41%). The knee injuries included 10 anterior collateral ligament (ACL), 3 posterior collateral ligament (PCL), 19 medical and lateral ligament injuries, and 22 meniscus injuries with some injuries overlapping. Ten patients (30%) underwent surgery (8 meniscectomy, two ligamentous repairs). Patients showed improvement in pain scores (p<0.0001) and the LEFS scores (p=0.004). Seventeen patients (57%) returned to full-time work and 11 (37%) were not working at the time of discharge with one patient performing part-time work, and one on re-training. Higher levels of pre (p=0.02) and post-treatment (p=0.03) depression and post-treatment anxiety (p=0.02) had a negative impact on a successful return to work. Most clients had proper investigations ordered by their family physicians in the community (24 plain x-rays, 11 US, and 21 MRI). Our team ordered only 6 plain x-rays and 6 new MRI. We found significant improvement in pain and disability in injured workers who received an expedited multidisciplinary care. Anxiety and depression were the most important predictors of poorer recovery and a less successful work status. The judicious use of costly imaging is expected to reduce the overall health care cost of an injury, while providing new important information such as adding a new diagnosis or changing the management

Foot pain and related problems are quite common in the community. It is reported that 24% of individuals older than 45 experienced foot pain. Also, it is stated that at least two thirds of individuals experiences moderate physical disability due to foot problems. In the absence of evaluation of risk factors such as limited ankle dorsiflexion in the early period of the diseases (Plantar fasciitis, Achilles Tendinopathy e.g.) and the lack of mobile systems with portable remote access, foot pain becomes refractory/chronic foot pain, secondary pathologies and ends with workload of 1., 2. and 3rd level healthcare services. In the literature, manuel and dijital methods have been used to analyze the ankle range of motion (ROM). These studies are generally based on placing protractors on the image and / or angle detection from inclination measurement by using the gyroscope sensor of the mobile device. Some of these applications are effective and they are designed to be suitable for measuring in a clinical setting by a physician or physiotherapist. To the best of our knowledge, there is no system developed to measure real-time ankle ROM remotely with collaboration of the patients. In this research, we proposed to develop an ankle ROM analyze system with smart phone application that can be used comfortably by subjects. We present a case of a 22-year-old male with a symptomatic pes planus. The mobile application, which was used for data collection, was designed and implemented for Android devices. Initially, before the mobile application home page is opened, a consent page was submitted to the acceptance of individual within the scope of Law (KVKK) data privacy. Then, the participant was asked to state his sociodemographic characteristics [age, gender, height, weight] and dominant side. No history of foot-ankle injury, trauma, and surgery was recorded. Activity pain of the foot was 6 according to visual anolog scale (VAS) in the mobile application. His ankle dorsiflexion was 15 ° by manuel goniometer. Besides, server was responsible for storing the collected data and ROM measurement. ROM was calculated by processing the foot video which was sent through the mobile application. During the processing phase, a segmentation model was used which was trained with image process and deep learning methods. With the developed system, we obtained the manual goniometric measurement result with 2 degrees deviation. As the application is calibrated, it is expected to approach the actual measurement of ROM. We can conclude that mobile app-goniometer result in dorsiflexion measurement is a novel promising evaluation method for ankle ROM. it will be easy and practical to detect and monitor risk factor of the diseases, decrease medical costs, provide health services in rural areas, and contribution to life quality and to reduce the workload on physicians and physiotherapist

Adductor strain is a common injury among football players. The adductor muscle group contains the three adductor muscles. (adductor longus, magnus and brevis) Adductor longus muscle is a triangular-shaped long muscle. This muscle originates from the superior ramus of the pubic bone and inserted into the middle part of the linea aspera. Adductor longus muscle is the most commonly injured muscle of adductors. Sudden acceleration, jumping, stretching, and kicking the ball are common causes of an adductor injury. Adductor muscle strains can result in missed playing time for football players. We present a 26-year-old man soccer player with pain in the left groin and proximal thigh. The symptoms had started during training and after kicking the ball with left foot (dominant side), he felt an acute pain in the groin region and proximal thigh. Despite the injury, he managed to finish the training. The team physician examined the patient immediately after training. The range of motion of both hip joints was in normal ranges and mild pain with adduction. There was a palpable mass at the inner proximal thigh during contraction of adductor muscles. There was no history of groin pain or adductor problems before this injury. Conventional radiographs showed no osseous abnormalities. 36 hours after the injury, MRI revealed acute grade IIB strain in the left adductor longus muscle, including both superior and inferior parts of the muscle. A hematoma was observed in the superior part of the left adductor muscle, with a craniocaudal length of 42 millimeters. There was an adductor muscle strain with hyperintensity extending for a craniocaudal length of approximately 12 centimeters involving more than 50% crosses sectional diameter of the muscle belly. Conservative treatment started immediately, consisting of cold therapy and soft tissue massage. Compression of the injured tissue using a 15-cm elastic bandage roll is done to limit bleeding and provide support. Iced water machine (Game Ready) was used. The team physician examined the player every day and prescribed physiotherapy protocol daily. Additionally, short interval follow-up MRI is used to evaluate the injury. (After 7 and 14 days of the injury) No injection was performed. The player is able to return to play immediately, despite MRI's strain images. The player started straight running 5 days later and joined to team training 8 days later and played 90 minutes-league-match 12 days after injury without any pain. No injection was performed. The player is able to return to play immediately, despite MRI's strain images. The player started straight running 5 days later and joined to team training 8 days later and played 90 minutes-league-match 12 days after injury without any pain. MRI is a useful technique in diagnosing trauma in football players presenting with groin pain. In this case, to estimate time-to-return-to-play, MRI alone is not strong evidence. MRI is a good option for follow up, but anamnesis and clinical examination is not inferior to diagnostic imaging

Chronic low back pain (cLBP) is a complex, multifaceted disorder where biological, psychological, and social factors affect its onset and trajectory. Consequently, cLBP encompasses many different disease variants, with multiple patient-specific mechanisms. The goal of NIH Back Pain Consortium (BACPAC) Research Program is to develop understanding of cLBP mechanisms and to develop algorithms that optimally match specific treatments to individual patients. To accomplish this, one research activity of BACPAC is to develop theoretical models for chronic low back pain based on the current state of knowledge in the scientific community, and to interrogate the relationships implied by the theoretical models using data generated by or available to BACPAC. The models consider biopsychosocial perspectives, and encompass both peripheral (i.e. low back) and central (i.e. spinal and supra-spinal) factors as well as proposed mechanisms of action of cLBP treatments. However, absent explanations, models/algorithms may fall short of regulatory requirements and clinician expectations, and ultimately may not be embraced by physicians and patients. To address this, BACPAC is developing a clinical utility roadmap (CUR) to clarify how models will be used in practice for selecting optimal treatments, monitoring response to treatment, and reducing health care utilization. This presentation will review the goals of BACPAC and how theoretical models and CUR are being used to support computational knowledge networks to integrate data from deeply phenotyped cLBP patients

Summary Statement. The purpose is to evaluate the effects of internet usage on new patient referral patterns to identify optimal patient recruitment and communication. Overall, social networking and internet may be an effective way for surgeons to recruit a wider patient population. Introduction. Prior studies in other medical specialties have shown that social networking and internet usage has become an increasingly important means of patient communication and referral. However, this information is lacking in the orthopaedics literature. In this study, we evaluate the means by which new patients arrive at orthopaedic clinics in a major academic center. The purpose is to evaluate the effects of internet or social media usage on new patient referral patterns to identify avenues to optimise patient recruitment and communication. Patients and Methods. New patients were recruited in a major academic orthopaedic clinic to complete a 15-item questionnaire with demographic information, social media use/networking and referral method. Data was collected for all orthopaedic sub-specialties and analyzed accordingly. Statistical analysis was performed. Results. Of the 752 responses, there were 66% female and 34% male responses. Responses were obtained from hand (142), sports medicine (303), foot and ankle (129), joints/tumor (95) and trauma (83) services. Overall, 51% report using social networking sites such as Facebook or Twitter. Of the patients that report not using social network sites, 92% are over the age of 40. Joints/tumor patients most commonly had seen another orthopaedic surgeon prior to their visit (59%) and had prior surgery (42%). Most patients traveled under 60 miles and were referred by their primary care physicians. Between 18–26% of all patients used a physician review website before consultation. The majority of the patients prefer communicating with their physician via the phone(68%) compared to email(32%). Independent associations found that sports medicine patients tend to be higher social networking users (35.9%) relative to other services (9.8–17.9%) and was statistically higher when compared to the joints/tumor service (P<.0001). The multivariate logistic regression model showed that the sports service was generally more likely to have social networking users with the exception of the foot/ankle service), however these differences were not statistically significant. The biggest indicator predicting social media usage in the orthopaedic population was age. The older the patient population, the less likely patients will use social networking sites. Non-doctorate patients were more likely to be social media users compared to doctorate level individuals, but was not statistically significant. Patients that lived from 120 to 180 miles from the hospital were significantly more likely to be social media users, as were patients that did research on their condition prior to their new patient appointment. Discussion and Conclusion. Orthopaedic patients who use social media are more likely to be younger, research their condition prior to their appointment and undergo an average day's travel (120–180 miles) to see a physician. Up to 26% of all patients have seen or used a physician review site prior to their visit. Despite the increased social media usage, most orthopaedic patients still prefer telephone communication with their physicians. Overall, social networking and internet may be an effective way for surgeons to recruit a wider patient population. In an increasingly competitive market, surgeons with younger patient populations (Sports Medicine) will need to utilise social networking and the internet to capture new patient referrals

The ankle radiograph is a commonly requested investigation as the ankle joint is commonly injured. Each radiograph exposes 0.01 mSv of radiation to the patient that is equivalent to 1.5 days of natural background radiation [1]. The aim of the clinical audit was to use the Ottawa Ankle Rule to attempt to reduce the number of ankle radiographs taken in patients with acute ankle injuries and hence reduce the dose of ionising radiation the patient receives. A retrospective audit was undertaken. 123 ankle radiograph requests and radiographs taken between May and July 2018 were evaluated. Each ankle radiograph request including patient history and clinical examination was graded against the Ottawa Ankle Rule. The rule states that 1 point(s) indicates radiograph series; (1) malleolar and/or midfoot pain; (1) tenderness over the posterior 6cm or tip of the lateral or medial malleolus (ankle); (1) tenderness over the navicular or the base of the fifth metatarsal (foot); (1) unable to take four steps both immediately and in the emergency department [2]. Patients who score 0 do not need radiograph series. Each radiograph was reviewed if a fracture was present or not. The clinical audit identified 14 true positives where the Ottawa Ankle Rule scored 1 and the patient had an ankle fracture, and 2 false negatives (sensitivity 88%). There were 81 false positives, and 23 true negatives (specificity 22%). Therefore, a total of 23/123 ankle radiographs were unnecessary which is equivalent to 34.5 days of background radiation. The negative predictive value of the Ottawa Ankle Rule in this audit was 92%. The low rate of Ottawa rule utilisation may unnecessarily cause patient harm that should be addressed. An educational intervention with physicians combined with integration of the Ottawa rule scoring in ankle radiograph requests is planned with re-audit in 6 months

Patients undergoing hip resurfacing arthroplasty (HRA) is typically reserved for highly active patients. Patient Reported Outcome Measures (PROMs) such as the Oxford Hip Score (OHS) are reported to have ceiling effects, which may limit physicians' ability to measure health gain in these patients. The Metabolic Equivalent of Task (MET) index is a validated compendium assigning energy expenditure to a wide range of activities; for example, a slow walk expends 2.9 kcal/kg/hour, golf expends 4.0 kcal/kg/hour, while moderate lacrosse typically expends 8.1 kcal/kg/hour. We hypothesized that for patients with high OHS (47–48) after HRA, the MET index could better discriminate between high-performing individuals. We evaluated 97 consecutive HRA patients performed by a single surgeon. They prospectively completed an online Oxford Hip Score. They also listed three activities which they had performed independently in the preceding 2 weeks with a Likert-scale slider denoting intensity of effort. Matched data-sets were obtained from 51 patients, from which 23 had OHS of 47–48 at 6-months. Their activity with the highest MET index was selected for analysis. The 23 patients' OHS improved from 29.3 ± 7.0 preoperatively to 47.6 ± 0.5 after 6-months, while their MET indices improved from 8.5 ± 3.7 to 12.9 ± 3.5 kcal/kg/hr. The activities performed by these high-performance individuals ranged from the lowest, pilates (8.05 kcal/kg/hour), to highest, running at 22km/hr (23 kcal/kg/hour). 45% of patients undergoing HRA in this cohort had OHS of 47 and 48 at 6-months after surgery. Unlike the OHS, the MET index described variation in physical activity in these high-performance individuals, and did so on an objective measurable scale

A rotator cuff tear is one of the most common traumatic and degenerative tendon injuries resulting in over 4.5 million physician visits in the US alone. Functional restoration of rotator cuff defects usually requires surgical repair, estimated at 300,000 cased in the US annually. However, postoperative retear of repaired tendons ranges from 20% in small to medium tears to over 90% in large and massive tears. Recently, augmentation with grafting materials to strengthen a reparable tear or to bridge an unrepairable defect has become a common and attractive strategy to reduce the retear rate, especially for large or massive tears. Current graft materials, however, have encountered great challenges in achieving these goals. To meet these challenges, we have developed an engineered tendon with layered tendon-fibrocartilage-bone composite (TFBC) from patellar-tibia unit revitalized by seeding bone marrow derived stem cells (BMDSCs) within the slices, and then reassembled to an engineered tendon. Both in vitro and in vivo results have shown that engineered TFBC enhance the biomechanical strength and biological healing using canine model

The widespread dissemination of high-quality research facilitates keeping up to date with evidence-based practice, but the vast quantity can be overwhelming to physicians and surgeons. Information graphics, abbreviated to infographics, convey information using visualisations and images in an engaging manner. This format of presenting research format is preferable to 80% of clinicians when compared to text articles, and the long-term retention of information has been shown to be improve by a factor of 6.5 when methods were compared. Journal club was audited in our institution over 3 months. A multi-choice questionnaire was constructed weekly so as to test the attendees' recall of the research presented on a weekly basis. After five weeks, infographics were introduced, and the attendees' recall was assessed again on a weekly basis at the end of each journal club. The introduction of infographics to journal club saw improved test results from the journal club attendees. Not only was information retention improved, but the duration of journal club reduced following the intervention. Research can be disseminated efficiently using infographics in place of conventional journal club presentations. Satisfaction rates among clinicians, both with information retention and journal club duration, demonstrate the benefit of their use in teaching hospitals

Background. Narcotics are commonly prescribed for pain control of orthopedic trauma but injury pattern and severity, in addition to patient factors, result in varying dosing requirements. These factors, coupled with increasing pressure to reduce narcotic consumption, highlight the importance of narcotic stewardship and comprehension of patient factors leading to higher pain control demands. The purpose of this study is to understand whether or not narcotic consumption is greater in patients who present to the emergency department with positive drug screen (utox) for illicit substances. Methods. We performed a retrospective chart review of 300 consecutive trauma activations during the 2015 calendar year. Of the patient cohort, 226 patients received a utox screen which represents the cohort for this study. Utox screen included amphetamines, barbiturates, benzodiazepines, cocaine, ethanol, methadone, phencyclidine, and tetrahydrocannabinol. Opioids given hospital stay were converted to oral morphine equivalents using ratios available in the current literature. The average daily equivalent was calculated for their total hospital stay and recorded. Patient injury severity score (ISS), age, gender, length of stay, readmission rates were also recorded. Statistical comparisons were made using SPSS version 23 (IBM, Aramonk, NY). Data distributions were examined with the Shapiro-Wilk test of normality between group comparisons were made with Mann Whitney U tests. Chi squared test was used to evaluate categorical data. Significance was set at p=0.05. Results. There were 108 (48%) positive utox tests of the 226 that received a utox test. There was no difference in gender distribution or age between the 2 groups. The calculated morphine equivalent consumption of the positive utox patient cohort was compared against the negative utox group. The median daily oral morphine equivalents in the positive utox group was 23.85 versus 12.05 for those with a negative utox screen. This was found to be statistically significant with a p value of 0.014. The average length of stay for the positive utox group was 3 days versus 2 days for the negative utox group. This also was statistically significant with a p value of 0.009. There was no statistical significance for ISS (5 in utox positive versus 5 in utox negative patients) nor was there any significance found in the rate of readmissions. Discussion. Our study shows that infividuals found to have positive utox screening for illicit drug use require more opioids for pain control and have longer hospital stays. These increased resource requirements exist despite no statistically significant difference in ISS. The high rate of positive findings and differences in patient clinical course support continued utox screening in trauma activation patients. When treating these patients, physicians should be aware of potential differences in pain management strategies and would likely benefit from multimodal pain control progam

Newer irreversible oral anticoagulants such as rivaroxaban, a direct factor 10a inhibitor, are increasingly employed to prevent thromboembolic events in atrial fibrillation (AF) patients, and to manage venous thromboembolism (VTE). Unlike warfarin, these agents require no monitoring and involve infrequent dose adjustment. We report the case of a patient treated with rivaroxaban for AF. Patient presented with unprovoked sudden onset right shoulder pain which clinically resembled shoulder haemarthrosis. A single case was anonymised and retrospectively reviewed through examination of clinical and radiographic data. A 70 year old female with known AF presented to Accident and Emergency with sudden onset of right shoulder pain and limited movement, which developed over one hour. The pain was constant, localised to the shoulder and without trauma. Past medical history included severe aortic regurgitation and associated thoracic aortic aneurysm, heart failure, atrial fibrillation and hypertension. Observations were normal upon admission with no haemodynamic compromise or pyrexia. Examining the right shoulder demonstrated distension of shoulder joint capsule, tenderness and a reduced range of movement. Temperature and neurovascular status in the right arm were normal. Investigations upon admission included an INR of 1.2. An anteroposterior right shoulder radiograph showed no evidence of fracture. Patient was managed conservatively with simple oral analgesia. Importantly, rivaroxaban was withheld for 5 days and symptoms resolved. Warfarin therapy was subsequently commenced instead as treatment for AF. Patient was discharged one week later and seen in clinic two weeks post-discharge. A full recovery occurred and with a full range of movement in the right shoulder. In the UK, current National Institute for Health and Care Excellence (NICE) guidelines recommend the use of factor 10a inhibitors, for prevention of stroke in AF patients, and following elective total hip and knee replacement operations to prevent VTE. In turn, rivaroxaban is increasingly prescribed as first line therapy. Whereas warfarin has a documented association with haemarthrosis, there is no primary literature evaluating the incidence of factor 10a therapy associated haemarthrosis. In our case, the unprovoked shoulder haemarthrosis resolved following rivaroxaban cessation. In comparison with warfarin, rivaroxaban is irreversible. With warfarin and a high INR, vitamin K can be used to reverse the anticoagulation. There is no equivalent for rivaroxaban. We suggest further studies into incidence of haemarthrosis associated with oral anticoagulant therapy be undertaken, and treating physicians be aware of such complication

To evaluate if young patients have a poorer functional outcome following Total Knee Arthroplasty surgery. Database of 700 consecutive Total Knee Arthroplasty patients from Scotland, UK was collected with Oxford Knee scores and American Knee Society Scores both pre-operatively and at sequential follow up reviews (PFC database, DePuy). Complication data was also collated. Patients were then age stratified into below 55, 56–64, 65–74 and over 75 groups. Analysis was performed using General Linear Model ANOVA (Minitab v10) comparing functional score change between pre operative and 2 year score data. No statistical difference was identified between the patient age groups and change in functional outcome scores (AKSS p=0.994; OKS p=0.368). All groups showed an improvement in functional scores over the 2 year period using both patients assessed (OKU) and physician scored outcomes (AKSS). There was no statistical difference in revision or infection rates. Recent data has suggested higher revision and infection rates in young patients undergoing Total Knee Arthroplasty (Scottish Arthroplasty Report 2012). The data from the PFC database does not show any change in infection or revision rates within this sample population and the data does also not support any variance in change in functional outcome with all groups showing improvement following TKA. The findings may be limited due to sample size of 700 patients

Frail patients with neck of femur fracture, amongst other medical problems, are frequently fast-tracked to orthopaedic wards to meet government A&E waiting time targets. This is a second cycle of audit since 2008 examining the safety of fast-tracking following individual critical incidents. Data was collected prospectively between March and June 2011 by the first on-call orthopaedic doctor. 56 patients (12 male), average age 81.2y (50–97) were fast tracked. 52 were correctly referred as intra/extracapsular fracture, however 4 did not have a neck of femur fracture. 9 patients were transferred with no verbal referral to the receiving orthopaedic doctor. On arrival to the ward, 8 patients were found to have abnormal observations and acute medical problems requiring immediate review from the physicians. There were a total of 150 omissions from a total of 456 points from the fast track protocol. Vital observations of patients fast-tracked after 2100h were worse (MEWS range 0 to 11) when compared with those fast-tracked prior to 2100h (MEWS range 0 to 3). This occurs at a time when medical staff support is minimal. Fast-tracking is a common practice amongst many district-general and some teaching hospitals in Scotland. These data support concerns from orthopaedic surgeons highlighting a need for more complete initial assessment and management in A&E prior to transfer to the ward. Recent evidence suggests medical optimisation of the multiple acute and chronic medical comorbidities common amongst patients with neck of femur fracture is the main facilitator of early surgery which significantly reduces post-operative mortality

Xiapex is a novel non-surgical intervention for the treatment of Dupuytren's contracture. It comprises a fixed-ratio mixture of two purified collagenolytic enzymes (AUX-I [clostridial type I collegenase] and AUX II [clostridial type II collagenase]) isolated from the medium of Clostridium histolyticum. Xiapex targets the contracture through the injection of enzymes into the pathologic diseased cords. The objectives of this study were to evaluate the safety and efficacy of Xiapex in patients with Dupuytren's Contracture, the recovery and associated use of health care resources. The study commenced in June 2011 and was completed in 11 months. 15 patients were screened for the study, 12 patients were eligible (10 male:2 female). All 12 patients completed the trial and 2 patients received multiple injections, one had two fingers affected and the other had two joints affected in one finger. Following screening visit to determine patient suitability, the patient received their first injection usually within 7 days. Xiapex was injected directly into the palpable cord. 24 hours after injection patients were reviewed and a “finger extension procedure” was performed if the cord had not spontaneously ruptured. Patients were then followed up at 7 days, 30 days and 6 months. Assessments at each visits included: Finger Goniometry, Physician and Subject Global Assessment and Satisfaction, Health Care Resource Utilization and URAM (function assessment) and adverse events. Of the 14 cords injected all ruptured after finger extension. No patient experienced any serious adverse events, but a number of more minor adverse events were recorded including skin tears, pain at injection site, swelling and bruising. At the time of final follow-up recurrence rates were 14%. In conclusion, Xiapex is suitable for appropriately selected patients who are affected by Dupuytren's contractures and who have a well-developed palpable cord

Due to working time restrictions a full-shift cross-covering system is commonplace. As more than one surgeon is responsible for trauma admissions in a 24-hour period a complete handover is paramount to ensure continuity of care. The purpose of this audit was to determine whether the introduction of a formal handover/admission form would improve this continuity with regards to prescription of venous thromboembolism (VTE) prophylaxis in hip fracture patients. In Stirling Royal Infirmary chemical VTE prophylaxis for hip fracture patients is 40mg enoxaparin at 6pm unless there is a contraindication. Over a 14-day period we prospectively documented the prescription of VTE prophylaxis and doses missed under the current admissions system. Following this a proforma was introduced that was to be exchanged at handover meetings. The proforma included patients' name/details, admission ward, and tasks to be completed during clerk-in, including VTE prophylaxis prescription. Tasks outstanding at handover had to be documented and completed by the subsequent doctor. Each form was signed and dated by the receiving doctor. We subsequently re-evaluated the prescription of VTE prophylaxis in hip fracture patients. Between 1/12/10-15/12/10, 23 patients were admitted with hip fracture. 12 had appropriate VTE prophylaxis, 6 missed one dose, 4 missed two, and 1 missed three all due to failure of prescription. Following the introduction of the proforma, 12 patients were admitted with hip fractures between 31/12/10-14/1/11. All were prescribed appropriate VTE prophylaxis and missed no doses. 1 patient was on warfarin and had enoxaparin prescribed but withheld until INR< 2.0. After the introduction of a handover form VTE prophylaxis prescription vastly improved. This proforma ensured that all elements of initial management were completed allowing for physician accountability, greater efficacy of handover and continuity of care

Discitis in childhood is rare. It can be difficult to diagnose, particularly in the younger child, often leading to a delay in initiation of appropriate treatment. It is not known whether it represents an infective or an inflammatory process. Our aim was to review all cases treated at a regional children's hospital since the introduction of the departmental database. A retrospective review (64,058 cases), for the period 1990-2008 was performed. 12 cases were identified (3 male/9 female), with a biphasic age distribution; eight [mean 22 months old (12-32)] and four [mean 12 years old (11-13)]. Mean time to diagnosis from onset was 22 days, (5-49). Symptoms varied with age, no one less than 28 months complained of back pain, while all over 28 months did, to a varying degree. All the younger children presented primarily with a gait abnormality. 92% (11/12) were apyrexial on admission. WBC and CRP were normal in 83% (10/12). Venous blood cultures were negative in 89% (8/9). Only ESR was mildly raised, mean 30 (10-65). Radiographs showed loss of intervertebral disc height in 91% (10/11), earliest by 10 days following onset symptoms, mean 28 days. A technetium bone scan was performed in 42% (5/12) and an MRI of the lumbar spine, in 58% (7/12). All were positive for discitis. All occurred in the lumbar spine, 50% at L3/4. Antibiotics were used in 11/12 (92%), flucloxacillin alone in the majority 9/11. One had non-steroidal medication alone. No form of brace was used. Mean follow-up was 13.3 months (2-36). In all, symptoms had resolved by mean 6.5 weeks (2-12). No recurrence was noted. The common features of childhood discitis are presented; knowledge of these may aid the physician to come to a more rapid diagnosis of this uncommon paediatric condition

Summary. In an in vitro tendon cell model, the tendon-specific gene expression up-regulation induced by PEMF negatively correlates with field intensity; moreover repeated lower-intensity PEMF treatments (1.5 mT) provokes a higher release of anti-inflammatory cytokines respect to the single treatment. Introduction. Tendon disorders represent a diagnostic and therapeutic challenge for physicians. Traditional treatments are characterised by a long recovery time and a high occurrence of injury relapses. Despite the growing clinical interest in pulsed electromagnetic fields (PEMFs) few studies on their effect on tendons and ligaments have been conducted. Tendon resident cells (TCs) are a mixed population, made up mostly by tenocytes and tendon stem/progenitor cells, which are responsible of the tissue homeostasis. Since studies on the effect of PEMFs on this cell population are conflicting, we evaluated the possible relation between PEMFs dosage and TCs’ response. In particular, we compared the in vitro effect of low and high PEMFs on TCs (PEMF-1.5 mT; PEMF-3 mT); moreover we assessed the results of repeated treatments (R-PEMF-1.5mT). Methods. TCs were isolated from the waste portion of semitendinosus and gracilis tendons of 7 healthy donors undergoing ACL reconstruction; at P4 they were exposed to different PEMF treatments (intensity: 1.5mT or 3mT; duration: 8 or 12 hours; periodicity: single or 3 treatments with an interval of 48h). Viability and DNA content were assessed by MTT and CyQuant, respectively, immediately at the end of the treatment (0d) and two days after (2d). Moreover, in order to accurately detected live and dead cells after the different treatments, Live&Dead staining was also assessed. At the same time points the expression of SCX, COL1A1 and VEGF were evaluated with RT-Real Time PCR, as well as the release of the cytokines TGFβ, IL6, IL10, IL1β, and TNFα by ELISA. Results. All the treatments applied for 12h increased TCs viability respect to untreated cells. However, respect to single PEMF-1.5mT, R-PEMF-1.5mT slightly decreased the TCs viability 2 days after 8 (−15%) and 12 hours (−9%) of exposure, whereas PEMF-3mT showed similar viability values. Nevertheless, the number of dead cells detected with Live&Dead assay was very low in all samples. All the tested PEMF treatments were able to relevantly enhance cell proliferation, with the exception of 12h R-PEMF-1.5mT, that reduces DNA content 2 day after treatment (−33%). All the treatments induced a significant increase of IL6, IL10 and TGFβ release respect to untreated cells (p<0.05), especially R-PEMF-1.5mT that showed higher values in comparison to the single PEMF-1.5mT treatment (p<.001). On the other hand pro-inflammatory cytokines (IL-1β and TNFα) production were not relevantly affected by any treatment. PEMF-3mT reduced the expression of tendon specific markers (SCX, COL1A1), whereas PEMF-1.5mT, above all as a single exposure, induced their up-regulation as well as the VEGF one, in comparison to untreated cells. Discussion/Conclusion. All PEMF treatments did not induced any cytotoxic events. Overall, a low intensity treatment, both single or repeated, allows to obtain a better in vitro TCs response in terms of anti-inflammatory cytokines release and tissue specific gene expression in comparison to higher electromagnetic field intensity (3 mT). In conclusion, these results suggest that PEMFs intensity negatively correlate with TCs in vitro response, whereas a repetition of low intensity treatment could positively influence tendon recovery. Further analyses on different models are needed to confirm these observations
