Nutritional support is an important tenant of perioperative medicine, with the aim to integrate the patient’s diet with food components that are needed in greater amounts to support surgical fitness. Regardless of the time available between the time of contemplation of surgery and the day of admission, a patient who eats healthy is reasonably more suitable for surgery than a patient who does not meet the daily requirements for energy and nutrients. Moreover, a successful education for healthy food choices is one possible way to sustain the exercise therapy, improve recovery, and thus contribute to the patient’s long-term health. The expected benefits presuppose that the patient follows a healthy diet, but it is unclear which advice is needed to improve dietary choices. We present the principles of healthy eating for patients undergoing major orthopedic surgery to lay the foundations of rational and valuable perioperative nutritional support programs. We discuss the concepts of nutritional use of food, requirements, portion size, dietary target, food variety, time variables of feeding, and the practical indications on what the last meal to be consumed six hours before the induction of anesthesia may be together with what is meant by clear fluids to be consumed until two hours before. Surgery may act as a vital “touch point” for some patients with the health service and is therefore a valuable opportunity for members of the perioperative team to promote optimal lifestyle choices, such as the notion and importance of healthy eating not just for surgery but also for long-term health benefit.Keywords: orthopedic surgery, prehabilitation, nutrition therapy, food and beverage, perioperative medicine, preoperative conditioning

The aim of this study was to determine the factors associated with failure of closed reduction of dislocated Austin Moore hemiarthroplasty for subcapital neck of femur fracture. There were 44 (1.8%) cases of dislocation for a 6-year period. There were 28 females and 12 males, and mean age was 85.6 years. Thirty-two patients (80%) had redislocations, and 13 patients (40%) required 2 or more closed reductions. Twenty-eight patients subsequently had a Girdlestone arthroplasty. Dementia and a previous failed closed reduction were associated with a higher failure rate (P = .03 and .04, respectively). Failed close reduction patients also had a higher 6-month mortality rate (P = .04). Closed reduction after Austin Moore hip dislocation has a higher failure rate significantly in patients with dementia and are associated with a higher mortality rate. We believe closed reduction should be avoided in these groups of patients, and Girdlestone procedure was considered after initial first dislocation. [ABSTRACT FROM AUTHOR]

Background: Osteoarthritis (OA) is a chronic degenerative joint disorder for which there is no known cure. Non-surgical management for people with mild-to-moderate hip OA focuses mainly on alleviating pain and maximising function via the National Institute for Health and Care Excellence (NICE) recommended combination of education and advice, exercise, and, where appropriate, weight loss. The CHAIN (Cycling against Hip pAIN) intervention is a group cycling and education intervention conceived as a way of implementing the NICE guidance., Methods: CycLing and EducATion (CLEAT) is a pragmatic, two parallel arm, randomised controlled trial comparing CHAIN with standard physiotherapy care for the treatment of mild-to-moderate hip OA. We will recruit 256 participants referred to the local NHS physiotherapy department over a 24-month recruitment period. Participants diagnosed with hip OA according to NICE guidance and meeting the criteria for GP exercise referral will be eligible to participate. Primary outcome is the difference in Hip Disability and Osteoarthritis Outcome Score (HOOS) function, daily living subscale between those receiving CHAIN and standard physiotherapy care. Secondary outcomes include performance-based functional measures (40 m walking, 30s chair stand and stair climb tests), ability for patient to self-care (patient activation measure) and self-reported health-related resource use including primary and secondary care contacts. The primary economic endpoint is the number of quality adjusted life years (QALYs) at 24 weeks follow-up. The study is funded by the National Institute for Health Research, Research for Patient Benefit PB-PG-0816-20033., Discussion: The literature identifies a lack of high-quality trials which inform on the content and design of education and exercise in the treatment of patients with hip OA and explore cost-effectiveness. CLEAT is a pragmatic trial which seeks to build further evidence of the clinical benefits of the CHAIN intervention compared to standard physiotherapy care within a randomised, controlled trial setting, and examine its cost-effectiveness., Trial Registration Number: ISRCTN19778222.

Rationale: Effective preoperative assessments of determinants of health status and function may improve postoperative outcomes., Aims and Objectives: We developed risk scores of preoperative patient factors and patient-reported outcome measures (PROMs) as predictors of patient-rated satisfaction and improvement following hip and knee replacements., Patients and Methods: Prospectively collected National Health Service and independent sector patient data (n = 30,457), including patients' self-reported demographics, comorbidities, PROMs (Oxford Hip/Knee score (OHS/OKS) and European Quality of Life (EQ5D index and health-scale), were analysed. Outcomes were defined as patient-reported satisfaction and improvement following surgery at 7-month follow-up. Univariable and multivariable-adjusted logistic regressions were undertaken to build prediction models; model discrimination was evaluated with the concordance index (c-index) and nomograms were developed to allow the estimation of probabilities., Results: Of the 14,651 subjects with responses for satisfaction following hip replacements 564 (3.8%) reported dissatisfaction, and 1433 (9.2%) of the 15,560 following knee replacement reported dissatisfaction. A total of 14,662 had responses for perceived improvement following hip replacement (lack of improvement in 391; 2.7%) and 15,588 following knee replacement (lack of improvements in 1092; 7.0%). Patients reporting poor outcomes had worse preoperative PROMs. Several factors, including age, gender, patient comorbidities and EQ5D, were included in the final prediction models: C-indices of these models were 0.613 and 0.618 for dissatisfaction and lack of improvement, respectively, for hip replacement and 0.614 and 0.598, respectively, for knee replacement., Conclusions: Using easily accessible preoperative patient factors, including PROMs, we developed models which may help predict dissatisfaction and lack of improvement following hip and knee replacements and facilitate risk stratification and decision-making processes., (© 2022 The Authors.

Introduction: Even though nearly 20 patients undergo hip replacement every hour just in Italy and the United Kingdom, it is unclear what are the most appropriate oral hydration practices that patients should follow before and after surgery. Improper administration can cause postoperative fluid disturbances or exacerbate pre-existing conditions, which are not an uncommon find in older subjects., Significance: Considering that the number of hip operations is expected to increase in the next years as well as the age of patients, it is important to recall the notions behind water balance, especially in light of modern surgical and anesthetic practices. This technical perspective discusses the perioperative changes in the hydration status that occur during hip replacement and provides the concepts that help clinicians to better manage how much water the patient can drink., Results: The points of view of the surgeon, the anesthetist, and the nurse are offered together with the description of mineral waters intended for human consumption. Before surgery, water should be always preferred over caffeinated, sugar-sweetened, and alcoholic beverages. The drinking requirements on the day of surgery should consider the water output from urine, feces, respiration, exudation, and bleeding along with the water input from metabolic production and intravenous administration of fluids and medications. Healthy eating habits provide water and should be promoted before and after surgery., Conclusions: The judgment on which is the most appropriate approach to oral hydration practices must be the responsibility of the multidisciplinary perioperative team. Nevertheless, it is reasonable to argue that, in the presence of a patient with no relevant illness and who follows a healthy diet, it is more appropriate to stay closer to dehydration than liberalizing water intake both prior to surgery and in the early postoperative hours until the resumption of normal physiological functions., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2022.)

Hospitals that treat more patients with osteoporotic hip fractures do not generally have better care outcomes than those that treat fewer hip fracture patients. Institutions that do look after more such patients tend, however, to more consistently perform relevant health assessments., Introduction: An inveterate link has been found between institution case volume and a wide range of clinical outcomes; for a host of medical and surgical conditions. Hip fracture patients, notwithstanding the significance of this injury, have largely been overlooked with regard to this important evaluation., Methods: We used the UK National Hip Fracture database to determine the effect of institution hip fracture case volume on hip fracture healthcare outcomes in 2019. Using logistic regression for each healthcare outcome, we compared the best performing 50 units with the poorest performing 50 institutions to determine if the unit volume was associated with performance in each particular outcome., Results: There were 175 institutions with included 67,673 patients involved. The number of hip fractures between units ranged from 86 to 952. Larger units tendered to perform health assessments more consistently and mobilise patients more expeditiously post-operatively. However, patients treated at large institutions did not have any shorter lengths of stay. With regard to most other outcomes there was no association between the unit number of cases and performance; notably mortality, compliance with best practice tariff, time to surgery, the proportion of eligible patients undergoing total hip arthroplasty, length of stay delirium risk and pressure sore risk., Conclusions: There is no relationship between unit volume and the majority of health care outcomes. It would seem that larger institutions tend to perform better at parameters that are dependent upon personnel numbers. However, where the outcome is contingent, even partially, on physical infrastructure capacity, there was no difference between larger and smaller units., (© 2021.

Total hip replacement (THR) is one of the most common elective orthopaedic operations. However, evidence suggests that despite postoperative pain improvements, aspects of longer-term physical performance, such as walking ability, do not reach the levels expected when compared to the general population. Walking is best assessed by using gait analysis. This review aims to explain the concept of gait analysis, its use to evaluate THR outcomes, and its proposed future importance when evaluating new technologies proposed to improve functional recovery in individuals undergoing THR surgery. Furthermore, this review discusses the advantages and challenges of gait analysis in THR patients and provides recommendations for future work.

Purpose: Hip hemiarthroplasty (HA) is a commonly performed operation. A post-operative radiograph forms part of the routine hip fracture pathway, although patients are often mobilised prior to this investigation. This study seeks to provide evidence for a pragmatic clinical change to optimise patient safety and allocate limited resources within the National Health Service (NHS)., Methods: We undertook a retrospective database review of 1563 HA procedures to assess whether the routine ordering of check radiographs played an important role in a patient's post-operative care., Results: 18 (1.2%) mechanical complications led to a return to theatre within 6 weeks of the index procedure. All were dislocations. Ten had a normal post-operative radiograph and five had documented suspicion of dislocation prior to radiography. The post-operative check radiograph was the sole identifier of dislocation in only three patients (0.2%). All three of these patients were pre-morbidly bed bound and non-communicative due to cognitive impairment (AMTS 0/10)., Conclusion: Unless a patient is pre-morbidly bed bound and cognitively impaired, routine post-operative radiography following HA surgery is of little clinical benefit, yet may carry considerable risk to the patient and cost to the NHS. A pragmatic compromise is to perform intra-operative fluoroscopic imaging., (© 2021. The Author(s).)

We describe the first intraprosthetic dislocations of a 22 mm head in a dual mobility hip replacement in the literature. This case emphasises the importance of information gathering and planning when dealing with arthroplasty complications. Furthermore, it highlights the necessity of adequate muscle relaxation and analgesia when dealing with hip dislocations. A 78-year-old patient presented to the emergency department (ED) with a spontaneous dislocation of her left dual-mobility total hip replacement 3 months after first-stage revision surgery for infection. Reduction via manipulation under analgesia was then attempted in the ED but was ultimately unsuccessful; an iatrogenic intraprosthetic dislocation of the polyethylene liner was sustained. Several factors may have contributed to liner dislocation: a failure to appreciate the implant type, multiple manipulations in ED were attempted under analgesia, but no sedation or muscle relaxation was administered to the patient. The patient subsequently underwent revision surgery., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2022. No commercial re-use. See rights and permissions.

Humeral metastases from renal cell carcinoma are not uncommon. Current surgical practice centres around adequate tumour resection, but often at the expense of functional outcome. The use of trabecular metal (TM) implants is well described in spine and joint surgery. However, their use as a reconstruction device in osseous tumour surgery has yet to be reported. We present our experience in using a TM vertebral body replacement device (VBR) in treating a patient with painful bilateral diaphyseal humeral metastases. Resection of the tumour resulted in defects which the TM-VBR was able to fill. The defect was then bridged with a locking plate and cables. At 2-year clinical and radiographic review, bony integration and a return to pain free, near-normal function was achieved., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2022.

Background: Hip fracture is a common and serious injury in the elderly. Hip arthroplasty is the most frequently performed procedure for patients with an  intracapsular hip fracture. The majority of national guidelines recommend total hip arthroplasty (THA) for more active patients. Literature indicates significant stability advantages for dual mobility (DM) acetabular components in non-emergent scenarios. Evidence supporting the use of DM in hip fracture patients is limited., Aim: We set out to ascertain if DM implants offer stability and/or functional advantages over standard THA in patients with hip fracture., Methods: We utilised our local National Hip Fracture Database to identify all patients undergoing either a standard or DM THA for hip fracture (n=477) We matched cohorts based on age, AMTS, mobility status pre-operatively, gender, ASA and source of admission. Our primary outcome of interest was functional status using the oxford hip score (OHS). Secondary outcome measures included  dislocation, fracture and deep infection requiring further surgery., Results: 62 patient pairs were available for this study. Mean OHS for DM THA was 41.5 and for standard THA this was 42.7 (p=0.58). There were 4 dislocations in the standard THA group and 0 with DM THA. No difference was seen with infection or peri-prosthetic fracture., Conclusion: This study demonstrates functional equivalence between DM and standard THA. In addition it shows a trend towards less dislocation with DM THA. Cost savings from less instability may outweigh initial prosthesis costs. This study suggests a suitably powered RCT using instability as the primary outcome measure is indicated., (Crown Copyright © 2021. Published by Elsevier Ltd. All rights reserved.)

Introduction: The National Hip Fracture Database of England, Wales and Northern Ireland (NHFD) is the largest such database in the world. Data errors in within the NHFD lead to spurious evidence which ultimately informs Orthopaedic, Anaesthetic and Orthogeriatric clinical practice., Materials and Methods: This multi-centre quality improvement study investigated, and sought to improve data inaccuracy within the NHFD. Hip arthroplasty episodes recorded between 2011-2020 were analysed for errors in operation, implant polarity and cementation., Results: Inaccuracies were observed in 20.5% of 3972 data entries. Following the introduction of a hip fracture clinical data administrator in each centre, inaccuracies reduced four-fold (5.2% of 559 data entries)., Conclusion: We advise caution when utilising NHFD data for research and audit purposes. In order to build a robust, accurate database for future research, we recommend the incorporation of specialist data administrators into the hip fracture multidisciplinary team., Competing Interests: Declaraion of Competing Interest All authors declare no conflict of interest., (Crown Copyright © 2020.

Introduction: Trauma patients are often required to make an informed decision about surgery within a short space of time. Coming to terms with their injury may mean they have limited bandwidth for absorbing information, and it may be that they don't appreciate the risks and benefits of surgery discussed during consent. Current consent practice puts the emphasis on the clinician to ensure that all reasonable steps have been taken to explain risks and benefits to patients. We propose the use of video animations that patients can watch prior to surgery as a means of improving their understanding and overall experience., Methods: The video script was written and evaluated so that a high standard was achieved using the "Discern" instrument. The experiences of a focus group of 5 patients were used to guide script content. Using GoAnimate (GoAnimate Inc., San Mateo) a video was made with voice over provided by local drama students. The video was shown to 30 consecutive patients over a 2 month period. We included any patient with an ankle fracture managed operatively who had been consented (form 1). Evaluation consisted of interview with patients consisting of 2 focussed questions and one open. Responses to the questions were collated and grouped into positive and negative descriptors., Results: 68 (81%) positive descriptors were recorded from patients' interviews versus 16 (19%) negative. Positive descriptors related to improved retention, information giving, technical detail, consolidations of information given during consent. Negatives were caveats that video couldn't replace face-to-face consent, the degree of detail being off-putting and not adding anything to standard consent., Conclusion: The video was well received by patients with subjective improvements being made to their understanding, retention and sharing of technical detail. The face-to-face discussion between patient and doctor remains very important to them and the video should look to augment this., Competing Interests: Declaration of Competing Interest The authors have no conflicts of interest to declare., (Copyright © 2020.

Objectives: The Cycling against Hip Pain programme is a 6-week exercise and education treatment pathway for people with hip osteoarthritis. Preliminary results of the Cycling against Hip Pain programme found significant improvements in clinical and patient-reported outcome measures for patients referred from primary care. This article evaluates the effectiveness of the changes made to the pathway in a quality improvement replication programme., Methods: The replicated Cycling against Hip Pain programme was delivered between February 2018 and September 2019 in a region of England with a high percentage of adults aged over 65 years. All participants were referred from the orthopaedic outpatient department of the funding hospital (secondary care). The programme was delivered at a local leisure centre and combined 30 min of education on osteoarthritis with 30 min of progressive static cycling, once a week for 6 weeks., Results: The participants on the replicated Cycling against Hip Pain programme did not differ from the original cohort in terms of age or pre-programme weight, however, presented with worse hip symptoms at baseline. Consistent with the findings from the original cohort, participants demonstrated significant improvements to their Oxford Hip Score, 30-s chair stand performance, Timed Up and Go score, Hip Osteoarthritis Outcome Score function and pain, EQ5D health rating, EQ5D-5L score and pain at rest and on weight bearing. In addition, participants reported an increase in knowledge, confidence and motivation to exercise., Conclusion: A 6-week cycling and education intervention for the treatment of hip osteoarthritis provided benefits to function, pain and quality of life for patients referred from secondary care. These results are consistent with findings from patients who were referred from primary care and further support the potential of the pathway in the conservative management of hip osteoarthritis., Competing Interests: Declaration of conflicting interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2020.)

Aims: Elective surgery has been severely curtailed as a result of the COVID-19 pandemic. There is little evidence to guide surgeons in assessing what processes should be put in place to restart elective surgery safely in a time of endemic COVID-19 in the community., Methods: We used data from a stand-alone hospital admitting and operating on 91 trauma patients. All patients were screened on admission and 100% of patients have been followed-up after discharge to assess outcome., Results: Overall, 87 (96%) patients remained symptom-free and recovered well following surgery. Four (4%) patients developed symptoms of COVID-19, with polymerase chain reaction ribonucleiuc acid (PCR-RNA) testing confirming infection., Conclusion: Based on our findings, we propose that if careful cohorting and screening is carried out in a stand-alone cold operating site, it is reasonable to resume elective operating, in a time of endemic but low community prevalence of SAR-Cov2.Cite this article: Bone Joint Open 2020;1-6:229-235., (© 2020 Author(s) et al.)

Background: Total hip replacement is recognised as a major risk factor for deep vein thrombosis (DVT). The aim of this study was to investigate the feasibility of using a novel neuromuscular electrical stimulation device (NMES) for DVT prevention in patients recovering from elective hip replacement surgery., Methods: Twenty-eight patients undergoing total hip replacement were randomised to receive postoperative treatment with either the NMES device or compression stockings continually from post-surgery until discharge (day 4). The primary outcome measure was the presence of symptomatic or asymptomatic DVT at 48 hours post-surgery and on the day of discharge from hip replacement surgery, as assessed by Duplex ultrasound. Secondary outcomes included hemodynamic responses to the devices, lower limb oedema, sit-to-stand and timed-up-and-go (TUG) scores, and hip range of motion., Results: In the compression stockings group, two cases of asymptomatic DVT were identified by Duplex ultrasound at 48 hours post-surgery. No cases were found in the NMES group. Patients in the NMES group demonstrated a general trend of a decrease in leg volume from post-surgery to discharge, whereas leg volume largely remained static for the compression stockings group. In addition, positive hemodynamic effects were found in favour of the NMES group in the non-operated leg. The change in TUG scores also favoured the NMES group (NMES: 150 ± 152%, compression stockings: 363 ± 257% (p=0.03)), whereas no differences in sit-to-stand scores or hip range of motion were observed., Conclusions: This study supports the feasibility of NMES as an alternative mechanical prophylaxis worn in the postoperative phase until discharge and provides important findings for clinicians considering novel mechanical prophylaxis options.

The Cycling against Hip Pain (CHAIN) programme is a six-week cycling and education treatment pathway for people with hip osteoarthritis. Preliminary results demonstrated significant improvements in clinical and patient-reported outcome measures following the course. Whilst the benefits of exercise for osteoarthritis are often reported in the short term, less is known about the long-term effects for this patient group. This study explores whether participants continued to self-manage their hip osteoarthritis five years after completing the course. A cross-sectional survey was conducted to collect data from participants who completed the CHAIN programme between October 2013 and February 2015 ( n = 96). Questionnaires were sent by post in April 2019, and then non-responders were followed up again four weeks later. Eighty-three (87%) participants responded to the survey. Five years (range 4-6) after completion of a six-week cycling and education programme, 37 (45%) participants had not returned to their general practitioner for further treatment of their hip pain, and 47 (57%) had not pursued surgical intervention. All participants were still engaged in at least one physical activity per week and many reported that they had purchased a bike (29%), joined a gym (30%) or cycled regularly (indoor cycling 25%, outdoor cycling 24%). Eighty (96%) participants reported an increase in knowledge of self-managing their symptoms. The findings from this study suggest that many patients are motivated to self-manage their hip osteoarthritis, five years following a six-week cycling and education treatment pathway that encourages lifestyle change., Competing Interests: The authors declare no conflict of interest.

Background and purpose - There is a large volume of heterogeneous studies across all Enhanced Recovery After Surgery (ERAS ® ) components within total hip and total knee replacement surgery. This multidisciplinary consensus review summarizes the literature, and proposes recommendations for the perioperative care of patients undergoing total hip replacement and total knee replacement with an ERAS program.Methods - Studies were selected with particular attention being paid to meta-analyses, randomized controlled trials, and large prospective cohort studies that evaluated the efficacy of individual items of the perioperative treatment pathway to expedite the achievement of discharge criteria. A consensus recommendation was reached by the group after critical appraisal of the literature.Results - This consensus statement includes 17 topic areas. Best practice includes optimizing preoperative patient education, anesthetic technique, and transfusion strategy, in combination with an opioid-sparing multimodal analgesic approach and early mobilization. There is insufficient evidence to recommend that one surgical technique (type of approach, use of a minimally invasive technique, prosthesis choice, or use of computer-assisted surgery) over another will independently effect achievement of discharge criteria.Interpretation - Based on the evidence available for each element of perioperative care pathways, the ERAS ® Society presents a comprehensive consensus review, for the perioperative care of patients undergoing total hip replacement and total knee replacement surgery within an ERAS ® program. This unified protocol should now be further evaluated in order to refine the protocol and verify the strength of these recommendations.

Background: Enhanced Recovery After Surgery (ERAS) focuses on optimizing each element on a treatment pathway and encouraging the patient to actively engage in his or her recovery and rehabilitation. It requires collaboration across a multidisciplinary team and has been successful in improving patient outcomes, length of stay (LOS), and costs for a wide range of surgical procedures, including musculoskeletal surgeries such as total hip and total knee replacement., Purpose: To examine the application of ERAS concepts to total shoulder replacement (TSR) surgery., Methods: Hospital Episode Statistics (HES) in England on LOS for TSR surgery were examined, and a review of literature on the use of ERAS concepts in TSR was undertaken., Results: Analysis of HES data suggested scope for improvement in reducing LOS. A review of the literature found some evidence of the use of ERAS concepts, particularly in multimodal pain management., Conclusions: Future research is now required for ERAS procedure-specific components for TSR surgery.

Objective: To establish whether attendance at an education class prior to total hip or knee replacement surgery as part of an enhanced recovery after surgery pathway could decrease length of hospital stay., Methods: A single-site, retrospective cohort study comparing length of stay in hospital for patients who attended and did not attend an education class prior to hip or knee replacement surgery. Patients were stratified into 3 groups according to the predicted likelihood of an extended inpatient hospital stay using the Risk Assessment Predictor Tool., Results: Mean length of stay reduced by 0.37 days for patients who received hip replacement (n = 590) (95% confidence interval (95% CI) -0.74, -0.01, p = 0.05) and by 0.77 days for patients who underwent knee replacement (n = 643) (95% CI -1.23, -0.31, p = 0.001) following attendance at a preoperative education class. Patients undergoing knee replacement who were considered at high risk of an extended hospital stay stayed, on average, 2.59 days less in hospital after attending the class (mean length of stay: 4.52 (standard deviation (SD) 1.26) vs 7.11 (SD 4.18) days (95% CI -4.62, -0.54, p < 0.02)., Conclusion: This study supports the inclusion of a preoperative education session in this context for both hip and knee replacement procedures, and indicates that this may be most beneficial for patients undergoing knee replacement who are at risk of an extended length of stay.

Background: Enhanced Recovery After Surgery (ERAS) has been successfully adopted across a range of procedures. This study explores whether there is scope to improve length of stay (LOS) for total ankle replacement surgery (TAR) in the UK by implementing ERAS pathways., Methods: Hospital Episode Statistics (HES) data (April 2015/March 2016) on LOS for TAR were analysed. A literature search was then carried out to examine whether there were any publications on outpatient TAR and/or the use of ERAS protocols., Results: Mean observed LOS was 3.3days (range 0-17.3) days. Case mix-adjusted expected LOS range was 2.0-5.7 days. It is likely that the wide observed LOS range is due to differences in local processes and pathways. Two papers were found by the literature search., Conclusions: TAR should aim to be outpatient surgery as the literature, and data demonstrating scope for improvement in LOS, suggest this should be possible., (Copyright © 2019 European Foot and Ankle Society.

Aim: Following soft tissue ankle injury, patients are often referred for out-patient physiotherapy and present symptoms including pain, reduced range of movement and function, and oedema. In this study, we assess the use of a neuromuscular electrical stimulation (NMES) device as an adjunctive therapy to reduce oedema in patients recovering from grade I and II ankle sprains., Methods: This was a single-centre, pilot randomised controlled study, recruiting patients referred to physiotherapy following an ankle sprain. Participants presenting with oedema were randomised to one of two treatment groups: (1) the current standard of care and (2) the current standard of care plus NMES use. Participants were identified in an emergency department and referred to a physiotherapy department for treatment 1 to 5 days following the injury and returned to clinic 7 days later., Results: Twenty-two participants completed the study and had full data sets for analysis (11 in each group). Mean volumetric displacement was reduced in the intervention group in comparison to the standard care group ( P = .011); however, there were no between-group differences in figure of eight measurements, function or pain scores. The device was well tolerated, with no device-related adverse events recorded., Conclusions: In this pilot, randomised controlled trial, NMES was well tolerated by patients following ankle sprain and demonstrated statistically significant improvements in oedema reduction as measured by fluid displacement. No other changes were observed. Further work will need to confirm the clinical significance and effect on longer term recovery post-ankle sprain., Competing Interests: Declaration of conflicting interests:The author(s) declared following potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Introduction: Total hip arthroplasty (THA) is currently a very successful operation but continues to evolve as we try to perfect techniques and improve outcomes for our patients. Robotic hip surgery (RHS) began with the 'active' ROBODOC system in the 1980s. There were drawbacks associated with the original ROBODOC and most recently, the MAKO robot was introduced with early promising results., Aim: The aim of this paper is to provide an up-to-date review surrounding this area and discuss the pros and cons of this technique., Methods: A literature review searching Medline, Embase, Ovidsp, Cochrane library, pubmed database and google scholar was performed searching keywords including: 'Robotic hip surgery', 'Robotic orthopaedic surgery', 'Computer assisted hip surgery', 'robotic arthroplasty', and 'computer assisted orthopaedic surgery'., Conclusion: Robotic hip surgery aims to tackle the limitations of the human factor in surgery by promising reproducible and reliable methods of component positioning in arthroplasty surgery. However, as orthopaedic surgeons, we must critically appraise all new technology and support the use providing there is sound robust evidence backing it.

Aim: The aim of this feasibility study was to investigate the potential role of a novel neuromuscular electrical stimulation (NMES) device in preventing the formation of oedema following total hip replacement (THR)., Methods: Successive primary THR patients were recruited into a randomised controlled trial. Participants were randomised to wear either the NMES device or compression stockings continually from post-surgery until discharge.The main outcome measure was presence of lower limb oedema, assessed by taking measurements of the circumference of the ankle, knee and thigh on the operated leg and non-operated leg, pre-operatively, post-operatively, at two days post-operatively and every day until discharge. Secondary objectives were to compare adverse events, the presence of asymptomatic and symptomatic deep vein thrombosis (DVT) and device tolerability between groups., Results: Data from 40 participants were analysed (NMES (n = 20), compression stockings (n = 20)). The NMES group had significantly less oedema and the device was found to be tolerable and safe., Conclusion: The results of this study suggest that the NMES is a safe and well tolerated alternative to compression stockings, which should be considered by clinicians seeking the additional benefit of reducing post-operative oedema. In addition the NMES device should be considered as part of a DVT prophylaxis.

Introduction: Incorrect acetabular component positioning during total hip arthroplasty (THA) may lead to dislocation, impingement, wear and revision. Surgeons commonly use the transverse acetabular ligament (TAL) as a landmark for acetabular component orientation. The posterior acetabular wall (PAW) is a structure easily viewed on plain radiography and its position can help guide acetabular component position. In this study, we examine the efficacy of preoperative radiographs in predicting cup position relative to the PAW., Methods: Prospective data was recorded on radiographic findings of the posterior wall (prominent, normal, deficient) on a consecutive series of 200 primary THAs utilising a standardised posterior approach. The final cup position relative to the wall was recorded (prominent, flush, deep). Cup inclination and version were then assessed by postoperative radiography and any instances of dislocation recorded., Results: There were 117 females and 83 males with a mean age of 66.5 years. 154 were recorded as having a normal PAW on radiographs, 152 had the cup positioned in line with the TAL and flush to the PAW. 29 had a deficient PAW and 27 of these had a cup positioned prominently with 17 having a prominent PAW and of these 16 a deep cup position. Postoperative radiographs showed a mean cup version of 20.8° and inclination of 44.7° using this method. There were 21 outliers (10.5%) with no dislocations at a minimum 12-month follow-up., Conclusions: The TAL is a continuation of the posterior labrum. As such, the posterior wall is a useful adjunct to and surrogate landmark for the TAL. It has the added advantage that it is visible on radiographs and so aids surgical planning with respect to cup positioning.

The use of trabecular metal (TM) implants in spine and joint surgery is well documented. However, their use has yet to be reported as an alternative to either allograft or autograft in the management of fracture non-unions. We present our experience in using a TM implant for treating a patient with a long-standing ulnar fracture non-union. Excision of devitalised bone resulted in a 17 mm defect which the TM implant was used to infill. The defect was then bridged with a locking plate. At 2-year clinical and radiographic review, bony union and a pain-free return to full function was noted. In this case, the use of a TM implant avoided the morbidity associated with an iliac crest autograft., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

Osteoarthritis of the hip is associated with pain, stiffness and limitations to activities of daily living. The aims of this quality improvement project were to introduce a service developed to promote the self-management of hip osteoarthritis through exercise and education and to assess the impact of the programme on pain, function and quality of life. The service was a six-week cycling and education programme and 119 participants took part. Statistically significant improvements were found for Oxford Hip Scores (Mean (SD) change 4.14, 95%, CI 3.02, 5.25, p < 0.001); Sit-to-stand scores (mean change 3.06, 95%, CI 2.33, 3.79, p < 0.001); EQ5D-5L Utility (mean change 0.06, 95%, CI 0.03, 0.09, p < 0.001); EQ5D VAS (mean change 7.05, 95%, CI 4.72, 9.39, p < 0.001); pain on weight-bearing (WB) (mean change 1.56, 95%, CI 0.77, 2.36, p < 0.001), HOOS function (median change (IQR) 7.35, 1.84 to 19.12, p < 0.001) and TUG test (median change 1.11, 0.31 to 2.43, p < 0.001). Participants reported improvements in pain and function; increased confidence in managing hip pain and an increase in motivation to exercise. These findings were supported by a patient and public involvement forum who suggested extending the programme to eight weeks. These results suggest that the service has potential in the management of hip osteoarthritis., (Copyright © 2016 The Authors. Published by Elsevier Ltd.. All rights reserved.)

This article examines the relevance of applying the Enhanced Recovery after Surgery (ERAS) approach to patients undergoing major spinal surgery. The history of ERAS, details of the components of the approach and the underlying rationale are explained. Evidence on outcomes achieved by using the ERAS approach in other orthopaedic and complex surgical procedures is then outlined. Data on major spinal surgery rates and current practice are reviewed; the rationale for using ERAS in major spinal surgery is discussed, and potential challenges to its adoption are acknowledged. A thorough literature search is then undertaken to examine the use of ERAS pathways in major spinal surgery, and the results are presented. The article then reviews the evidence to support the application of individual ERAS components such as patient education, multimodal pain management, surgical approach, blood loss, nutrition and physiotherapy in major spinal surgery, and discusses the need for further robust research to be undertaken. The article concludes that given the rising costs of surgery and levels of patient dissatisfaction, an ERAS pathway that focuses on optimising clinical procedures by adopting evidence-based practice and improving logistics should enable major spinal surgery patients to recover more quickly with lower rates of morbidity and improved longer-term outcomes., (Copyright © 2015 Elsevier Ltd.

This review presents current virtual reality based training simulators for hip, knee and other orthopaedic surgery, including elective and trauma surgical procedures. There have not been any reviews focussing on hip and knee orthopaedic simulators. A comparison of existing simulator features is provided to identify what is missing and what is required to improve upon current simulators. In total 11 hip replacements pre-operative planning tools were analysed, plus 9 hip trauma fracture training simulators. Additionally 9 knee arthroscopy simulators and 8 other orthopaedic simulators were included for comparison. The findings are that for orthopaedic surgery simulators in general, there is increasing use of patient-specific virtual models which reduce the learning curve. Modelling is also being used for patient-specific implant design and manufacture. Simulators are being increasingly validated for assessment as well as training. There are very few training simulators available for hip replacement, yet more advanced virtual reality is being used for other procedures such as hip trauma and drilling. Training simulators for hip replacement and orthopaedic surgery in general lag behind other surgical procedures for which virtual reality has become more common. Further developments are required to bring hip replacement training simulation up to date with other procedures. This suggests there is a gap in the market for a new high fidelity hip replacement and resurfacing training simulator., (Copyright © 2015 IPEM. Published by Elsevier Ltd. All rights reserved.)

Management of the mobile elderly patient who sustains an intra-capsular neck of femur fracture remains controversial. Current evidence is mixed as to whether total hip arthroplasty (THA), which confers higher surgical and dislocation risk, is significantly superior in function and in reduced rates of reoperation when compared to bipolar hemi-arthroplasty. A group of 110 patients with an intra-capsular NOF fracture who had undergone either THA or Bipolar hemi-arthroplasty and were still alive at the time of follow up were retrospectively identified and matched using the National Hip Fracture Database. Matching criteria included ASA, age, sex, pre-op mobility, pre-op AMTS and source of admission. Follow up was by postal questionnaire. Mean follow up was 24 months in both groups (Range; Bipolar 12-36 months, THA 12-38 months). There was no significant difference in pre-operative Tonnis grade, postoperative Oxford Hip Score (OHS) or Short Form 36 (SF-36) scores between the two groups. 12 dislocations in 5 patients occurred in the THA group and none in the bipolar group. 33/55 Bipolar patients were discharged to their own home compared to 35/55 in the THA group. None of the bipolar hemi-arthroplasties were revised to THA. Higher complication rates were experienced in the THA group with no increase in function., (Copyright © 2015 Elsevier Ltd.

A 71-year-old man presenting with hip osteoarthritis, with a complex range of comorbidities was referred by his general practitioner to CHAIN (Cycling against Hip PAIN), a 6 week programme developed to aid self-management of hip osteoarthritis through exercise, education and advice, as defined by the National Institute for Health and Care Excellence (NICE) guidelines. Significant improvements were seen in Oxford hip score, the Hip disability and Osteoarthritis Outcome Score (HOOS) - function score, sit-to-stand test, timed up and go test, pain scores and hip flexion. There was also a weight loss of 2.1 kg. The man reported 'an amazing difference' in his affected hip and leg, and improved fitness. Many clinicians would have questioned the man's suitability for the programme due to his coexisting medical conditions. This case study shows that patients may be much more able than we think to achieve significant improvement with exercise., (2015 BMJ Publishing Group Ltd.)

Introduction: Fifth metatarsal fractures are common and the outcome has been reported; however, prospective studies reporting the functional outcome using validated questionnaires are lacking in the literature. The aims of this study were to determine whether fifth metatarsal fractures remain symptomatic in the medium term and whether the fracture type influences outcome., Methods: Over the course of a year, 117 patients (62 avulsion fractures, 26 Jones fractures, 29 shaft fractures) were followed up (1 month, 4 months, 12 months), with functional outcome assessed using the Foot Function Index (FFI)- and Short Form 36 (SF36)-validated questionnaires., Results: The FFI reduced (function improved) over the course of the year from 22.0 (8.4-38.5) at 1 month to 0.0 (0.0-4.2) at 4 months, to 0.0 (0.0-1.3) at 1 year. There was no significant difference in the FFI scores with regard to gender or fracture type. Pain scores were also observed to decline over the year, with no significant differences between fracture types. However, while the severity of pain was low, the numbers of people reporting pain were relatively high. At 1 month, >80% of patients reported ongoing pain (83% avulsion, 88% Jones and 83% shaft), reducing to 38% at 4 months and 28% at 1 year. At final follow-up, 25% with an avulsion fracture, 28% with a Jones fracture and 33% with a shaft fracture reported pain., Conclusions: While 25-33% of patients continue to experience pain at 1 year, <10% experience any limitation of their activities. At the final follow-up at 1 year, there were no significant differences in functional outcome by fracture type, gender or patient age. Patients should be advised about the likelihood of ongoing low-level symptoms, even after a year from injury in this previously presumed innocuous injury., (Copyright © 2014.

We aimed to determine whether cemented hemiarthroplasty is associated with a higher post-operative mortality and rate of re-operation when compared with uncemented hemiarthroplasty. Data on 19 669 patients, who were treated with a hemiarthroplasty following a fracture of the hip in a nine-year period from 2002 to 2011, were extracted from NHS Scotland's acute admission database (Scottish Morbidity Record, SMR01). We investigated the rate of mortality at day 0, 1, 7, 30, 120 and one-year post-operatively using 12 case-mix variables to determine the independent effect of the method of fixation. At day 0, those with a cemented hemiarthroplasty had a higher rate of mortality (p < 0.001) compared with those with an uncemented hemiarthroplasty, equivalent to one extra death per 424 procedures. By day one this had become one extra death per 338 procedures. Increasing age and the five-year co-morbidity score were noted as independent risk factors. By day seven, the cumulative rate of mortality was less for cemented hemiarthroplasty though this did not reach significance until day 120. The rate of re-operation was significantly higher for uncemented hemiarthroplasty. Despite adjusting for 12 confounding variables, these only accounted for 15% of the observed variability. The debate about the choice of the method of fixation for a hemiarthroplasty with respect to the rate of mortality or the risk of re-operation may be largely superfluous. Our results suggest that uncemented hemiarthroplasties may have a role to play in elderly patients with significant co-morbid disease., (©2014 The British Editorial Society of Bone & Joint Surgery.)

Background: Between August 2007 and May 2009, 2128 consecutive patients underwent either primary hip or knee joint replacement surgery at our institute on an enhanced recovery pathway. We aimed to investigate the potential benefits of this pathway in patients over the age of 85 years., Methods: Data extracted from Hospital Episode Statistics were analysed. This data are prospectively collected and independently collated., Results: In all patients median length of stay was reduced when compared with both our own data before the introduction of the pathway (6 to 4 days) and national averages over the same time period for both hip and knee replacements (5 to 4 days). Difference in length of stay was most pronounced in the group of patients aged 85 years and over (9 to 5 days for total hip replacement and 8 to 5 days for total knee replacement). Nearly all patients were discharged directly home (97.4%). Readmission rates were over 45% lower in patients aged 85 and over when compared with national averages (5.2 vs. 9.4%)., Conclusions: This is the first series in the literature to assess the role of enhanced recovery pathways in the very elderly. This study not only shows that successful fast track rehabilitation can be achieved in the very elderly population undergoing elective joint replacement surgery, but that it is this cohort of vulnerable patients who have the most to gain from such multidisciplinary recovery programmes., (© The Author 2014.

Ankle fractures are common orthopedic injuries requiring reduction and cast immobilization or fixation. Fractures fixed in a malreduced (misaligned) position can require revision surgery. However, because this has been a relatively rare occurrence, little is known about the complications that can occur after such surgery. We reviewed all adult closed ankle fractures that underwent revision surgery for technical failure in a regional trauma hospital from January 2007 to January 2010. Those with open fractures and those who required external fixation at any point in their treatment were excluded. Nine patients underwent revision surgery during the study period. Of these 9 patients, 3 (33%) developed a deep infection, all with positive microbiology cultures for methicillin-sensitive Staphylococcus aureus. Each of these patients underwent removal of the metalwork and wound debridement, followed by plastic surgery free flap coverage. In addition to the 3 infection cases, those with noninfected complications included 1 patient (11%) with chronic regional pain syndrome, 1 (11%) with failure of plate fixation, and 1 (11%) with persistent pain requiring arthroscopy and debridement. The overall incidence of complications was 66.67% in this group of 9 patients who had undergone revision surgery for the treatment of a malreduced malleolar ankle fracture. Although our observational study involved a small subset of patients who had undergone surgical repair for ankle fracture, we suggest that if revision surgery will be undertaken, the high incidence of infection and the potential need for plastic surgery should be highlighted during the consent process before the original, open reduction internal fixation procedure., (Copyright © 2014 American College of Foot and Ankle Surgeons.

Background: Hip fracture is a common injury with associated high mortality. Recent drives by the Department of Health have sought to prioritise these patients' care. In April 2010, the Best Practice Tariff was introduced in England and Wales. This offers financial incentives to institutions that provide holistic care and surgery within 36h for hip fracture patients. The England and Wales National Institute for Health and Clinical Excellence (NICE) published its first guidance on hip fracture management in June 2011, and emphasised the need for surgery on the day or day after admission. In spite of the emphasis placed on this injury, the predictors of in-hospital mortality remain ill-defined. In particular the effect of the timing of surgery remains contentious., Objective: To address the issues raised by NICE around surgical timing and examine whether surgery before a 36h watershed improves survival. In addition, to examine survival outcomes for each 12h watershed following admission., Materials and Methods: Prospectively collected data on 2056 patients presenting to our unit with hip fractures between February 2008 and May 2011 were retrospectively reviewed. Multivariate regression analysis was used to correct for confounders, and so determine the effect of various parameters on in-patient mortality., Results: Age (p<0.0001), male-gender (p<0.0001), source of admission (p<0.05), ASA-grade (p<0.0001) and delay of surgery (p<0.01) were associated with an increased risk of in-hospital mortality. The adjusted odds of in-hospital mortality were 1.58 (p<0.05) times higher in those undergoing surgery after 36h compared to surgery before this time. Early surgery (within 24h) resulted in reduced in-hospital mortality when compared to the 36h watershed. Similarly ultra-early surgery (within 12h) was even better still (adjusted odds ratio 3.9 p<0.05)., Conclusions: Expeditious surgery is associated with improved patient survival. Other predictors of in-hospital mortality include age, gender, in-hospital fracture and ASA-grade. Ultra-early surgery (within 12h) reduces risk of in-hospital mortality., (Copyright © 2012.
