Aim. Swedish guidelines on antibiotic prophylaxis in arthroplasty surgery recommend cloxacillin in fixed doses that pay little attention to the patient's renal function and weight. Nevertheless, there are no studies on whether the resulting free prophylactic cloxacillin in vivo concentrations are optimal. We aimed to evaluate whether the current recommended prophylactic dosage of cloxacillin is adequate. Method. We performed a prospective two-centre study, measuring the free (active) cloxacillin concentrations in plasma throughout surgery, in patients subject to primary hip and knee prosthetic joint replacements, aiming at 100 patients per centre. To account for plasma-bone exposure differences, concentrations were considered adequate if twice the epidemiological cut-off value for cloxacillin concerning wild type Staphylococcus aureus whereas two-three times were labelled threshold values. The two enrolling hospitals are acute care hospitals in central Sweden, also performing 600 - 1200 primary hip and knee joint arthroplasties annually. All patients scheduled for elective primary hip or knee replacements from January 2022 to April 2024 were eligible for participation. Exclusion criteria were allergy towards penicillins, cognitive disorders leading to inability to sign informed consent, and an absence of interpreter in case of a patient not speaking Swedish or English. Results. We present results from the first 49 patients included. Four patients had free cloxacillin concentrations below cut-off (8.2%). These four cases had prolonged surgeries of 77-100 minutes. An additional 5/49 (10.2%) had threshold values. Conversely 5/49 (10.2%) cases had concentrations exceeding 15 times the needed. No cases with threshold or low cloxacillin concentrations were attributable to a lack of concerning timing and dosing of cloxacillin. All concentrations were above or equal to our cut-off at the start of surgery. Eighteen percent of patients were of normal of weight (BMI 18.5- 25). Of the rest 4% were morbidly obese (BMI >40), 41% obese (BMI 30-40) and 37% overweight (BMI 25-30). Twenty seven percent (43/159) had diabetes and 45% suffered cardiac disease. Conclusions. Some patients in our cohort had insufficient active cloxacillin levels at the end of prosthetic joint surgery. Previous studies indicate that insufficient prophylactic antibiotic concentrations might lead to an enhanced risk of prosthetic joint infections. Other patients were massively overdosed, leading to unnecessary ecological effects and potentially adverse reactions. As inadequate cloxacillin concentrations were not associated with a lack of compliance to current guidelines a change in practise might be needed. Our final results may help to determine how dosing should be adjusted

The Australia and New Zealand Sarcoma Association established the Sarcoma Guidelines Working Party to develop national guidelines for the management of Sarcoma. We asked whether surgery at a specialised centre improves outcomes. A systematic review was performed of all available evidence pertaining to paediatric or adult patients treated for bone or soft tissue sarcoma at a specialised centre compared with non-specialised centres. Outcomes assessed included local control, limb salvage rate, 30-day and 90-day surgical mortality, and overall survival. Definitive surgical management at a specialised sarcoma centre improves local control as defined by margin negative surgery, local or locoregional recurrence, and local recurrence free survival. Limb conservation rates are higher at specialised centres, due in part to the depth of surgical experience and immediate availability of multidisciplinary and multimodal therapy. A statistically significant correlation did not exist for 30-day and 90-day mortality between specialised centres and non-specialised centres. The literature is consistent with improved survival when definitive surgical treatment is performed at a specialised sarcoma centre. Evidence-based recommendation: Patients with suspected sarcoma to be referred to a specialised sarcoma centre for surgical management to reduce the risk of local recurrence, surgical complication, and to improve limb conservation and survival. Practice point: Patients with suspected sarcoma should be referred to a specialised sarcoma centre early for management including planned biopsy

We evaluated the quality of guidelines on thromboprophylaxis in orthopaedic surgery by examining how they adhere to validated methodological standards in their development. A structured review was performed for guidelines that were published between January 2005 and April 2013 in medical journals or on the Internet. A pre-defined computerised search was used in MEDLINE, Scopus and Google to identify the guidelines. The AGREE II assessment tool was used to evaluate the quality of the guidelines in the study. . Seven international and national guidelines were identified. The overall methodological quality of the individual guidelines was good. ‘Scope and Purpose’ (median score 98% interquartile range (IQR)) 86% to 98%) and ‘Clarity of Presentation’ (median score 90%, IQR 90% to 95%) were the two domains that received the highest scores. ‘Applicability’ (median score 68%, IQR 45% to 75%) and ‘Editorial Independence’ (median score 71%, IQR 68% to 75%) had the lowest scores. . These findings reveal that although the overall methodological quality of guidelines on thromboprophylaxis in orthopaedic surgery is good, domains within their development, such as ‘Applicability’ and ‘Editorial Independence’, need to be improved. Application of the AGREE II instrument by the authors of guidelines may improve the quality of future guidelines and provide increased focus on aspects of methodology used in their development that are not robust.

Abstract. Background. In 2018 NICE produced their guidelines with regards to the prevention of hospital-acquired thrombosis which extended the age range to include 16- and 17-years old patients, suggesting that these patients are risk assessed and receive thromboprophylaxis if indicated. We analysed the incidence of VTE in this age group in our institution and found it to be extremely low and often not related to risk factors commonly included in adult risk assessment tools. Methods. We retrospectively reviewed the data of 13,951 patients aged 16- and 17-years of age in our admission database at the University Hospitals of Leicester (UHL) over a period of 7 years between 2013 and 2019. This was cross-referenced with our imaging database which identified scans carried out for suspected Venous Thromboembolism (VTE). Results. There were 1,275 admissions and 12,676-day-case attendances over the study period. Of these, 145 patients had scans for suspected VTE. 13 patients had positive scans and fulfilled the inclusion criteria. Of the 13 positive scans, 10 were excluded and 3 patients were included in the study. Conclusion. This study shows that the risk of VTE in the 16- and 17-year-old age group is extremely low in patients attending hospital (0.1% in admitted patients and 0.007% in day attenders). We question whether routine risk assessment for VTE in this age group, especially using existing adult tools, is efficacious. The guidance acknowledges the evidence for prescribed drugs is both lacking and the prescription for such agents being outside their Licencing Authorisation

After decades of clinical experience and hundreds of studies, the ideal method of deep vein thrombosis (DVT) prophylaxis remains controversial. One of the most widely quoted publications on the subject in recent years has been the guidelines published by the American College of Chest Physicians (ACCP). The seventh and eighth ACCP Conference on Antithrombotic Therapy and Prevention of Thrombosis were published in Chest in 2004 and 2008 respectively. The highest level recommendation (1-A) was reserved for Warfarin at a relatively high dose (target international normalised ratio (INR) of 2–3), Low Molecular Weight Heparin (LMWH), or Fondaparinux for a minimum of 10 days for both total hip and total knee replacement. These agents were recommended for all patients, regardless of their relative risk of bleeding or risk of venous thromboembolism (VTE). These recommendations were found to be aggressive by the standards of most orthopaedic surgeons and a number of issues were identified with the methodology and resulting recommendations of the ACCP including: The emphasis on multicentre randomised clinical trials that are enormously expensive and strongly weighted towards pharmaceutical sponsored studies, methodology that prevented inclusion of studies of lower cost, lower tech options such as aspirin or lower dose Warfarin since randomised trials on a large scale are not available due to lack of funding or pharmaceutical company interest in generic low-cost options, lack of consideration of pneumatic compression options such as newly available mobile foot pumps with chips for monitoring compliance, financial conflict of interest of virtually all of the authors of the guidelines and the fundamental problem with utilising asymptomatic DVT as a study endpoint. The concerns with the aggressive nature of these recommendations were confirmed by studies from two academic centres which reported a high incidence of wound and bleeding complications when changing to a 1-A protocol. Recent studies indicate that readmissions following joint replacement are much more likely to be due to wound drainage and bleeding complications than DVT or pulmonary embolism (PE). In response to these concerns, the AAOS released guidelines in 2008 that were updated in 2011. The resulting recommendations represented a dramatic departure from the ACCP guidelines. Clinically crucial endpoints such as PE and death were utilized in the analysis rather than asymptomatic DVT, which was the criteria utilised by the Chest Physicians and the 2011 recommendations also considered symptomatic DVT. The AAOS guidelines consider patient risk category rather than making a uniform recommendation for all patients. Much more discretion is given to surgeons to utilise less aggressive prophylactic strategies including aspirin and foot pumps. In 2012, the ninth edition of the ACCP guidelines was published and many of the concerns previously expressed over prior editions were successfully addressed. Conflict of interest among the authors was much less of an issue, there was more attention placed on symptomatic events and clinically important complications, and a wider scope of literature was considered. The resulting guidelines represented a dramatic departure from previous recommendations. Aspirin and pneumatic compression were elevated to level 1 recommendation status along with potent drug regimens such as injectable drugs (LMWH and Xa inhibitor) as well as the new oral Xa inhibitors and antithrombin agents. When pneumatic compression devices are utilised, the use of a battery powered device capable of recording compliance was recommended. Patient risk status as well as patient preference were also considered. The new ACCP guidelines have successfully addressed many of the concerns previously addressed and are much more in line with the AAOS guidelines. It is anticipated that the federal Surgical Care Improvement Project (SCIP) guidelines for VTE prophylaxis will be released in 2013 and will also embrace the changes recommended by the ACCP. It is further likely that the AAOS and ACCP guidelines are close enough that they may well join forces in the near future and release a single unified document

Patients who present with a fractured neck of femur (NOF) have a significant rate of morbidity and mortality. In 2011, the National Institute for Health and Care Excellence (NICE) published clinical guidelines in order to improve these rates. Within this guideline NICE state that surgery should be performed on all NOF fractures within 36 hours. Within ABMU Health board the 1000 Lives Campaign goes a step further and aims to operate on 90% of patients within 24 hours. This study investigates the effect of an additional NOF theatre list on compliance to these national guidelines. This retrospective study was performed between October-December 2013 and December-February 2015. The first period of data collection represents a daily trauma list whilst the second period allowed an additional NOF theatre list. Data was collected using the National Hip Fracture Database and the Trauma Theatre List. The number of patients meeting the national guidelines increased with the presence of an additional theatre list (75.19% v 60%). This represents a reduction to the average time to theatre of 4 hours and 30 minutes (29:47 v 34:17). The additional theatre list improved prioritisation of patients with NOF fractures on the list (29.46% v 13.33% listed first on list) and reduced the rate of cancellations (19.38 v 29.17%). During this study Morriston Hospital did not meet national guidelines, however an additional theatre list did significantly improve average time to theatre. This study highlights the significant impact a dedicated NOF fracture theatre list can have. Winner – Best Paper Award

Diagnosis of complex regional pain syndrome (CRPS) can be challenging. We explore the role of fracture clinic in diagnosis and management with a closed-loop audit of new guidelines. We retrospectively reviewed patients with CRPS over 3.5 years. We determined the delay from injury to commencement of treatment and monitored symptoms. New guidelines were introduced to fracture clinic in January 2013. The Budapest Criteria aids diagnosis. GAD-7 and PHQ-9 patient questionnaires grade symptoms. Orthopaedic surgeons prescribe nortriptylline or pregabalin, refer to physiotherapy and review patients after six weeks. We re-audited prospectively after implementing these guidelines. The first audit cycle found 11 patients in 3.5 years. The mean delay to anti-neuropathic medication from injury was 4.7 months. Two patients required psychotherapy, one intravenous pamidronate, three inpatient physiotherapy under nerve blocks and two spinal cord stimulators. After implementing guidelines, there were 14 patients with CRPS in 9 months. All but two patients received anti-neuropathic medication on the day of diagnosis. All patients treated appropriately improved markedly within 4–12 weeks. No patients required escalation of treatment. Our guidelines increased pick-up rates of CRPS, diagnoses were made earlier and treatment started sooner. Physiotherapy modalities remained varied, however, early anti-neuropathic treatment led to a rapid improvement in all cases

Background. In 2009, NICE CG 88 guideline on the management of non-specific low back pain was published. We looked at whether the introduction of these guidelines has had an impact on the management of back pain within primary care. Methods. Patients with non-specific low back pain (> 6 weeks but < 12 months) attending spinal outpatient clinic in UHL between 2008 and 2011 were asked to complete questionnaires. Two groups were studied, the first prior to the publication of NICE guidelines, and the second afterwards. Patients with radicular, stenotic and red flag symptoms were excluded. Key audited treatment standards assessed included manual therapy, acupuncture, focused structured back exercise program, supervised group exercise program and lastly referral to a combined physical and psychological treatment program. Compliance with not using X-ray or MRI and treatment modalities such as injections, laser therapy, ultrasound therapy, lumbar supports, traction and TENS therapy was assessed. Secondary outcomes included VAS (back, leg pain), Oswestry Disability Index, MSP and MZD. Primary outcomes analyzed using 1-sided Fisher's exact test and secondary outcomes using two sample t tests. Results. 46 patients (pre-guidelines) and 34 patients (post-guidelines) were studied. Key findings showed significant deterioration in the institution of manual therapy in the post guidelines group (p value = 0.032) and an increase in use of MRI scan in post guidelines group (p value = 0.005). Deterioration in the mean presenting VAS for leg pain in post guidelines group noted. No significant difference between groups in the mean scores for VAS for back pain, ODI, MSP and MZDI. Conclusion. Our study suggests that the introduction of NICE guidelines on the management of low back pain has not yet influenced management in primary care. This may be due to lack of awareness of its implementation or due to adherence to local guidelines

The anatomy of the prevertebral region of the neck is of vital importance to orthopaedic surgeons when managing cervical spine trauma. Lateral radiographs are used in the acute assessment of this area as they are readily available and cost effectiveness. Thickening of the retropharyngeal space on a radiograph may be highly suggestive of serious and life-threatening pathologies. Accurate interpretation of radiological evidence is essential to assist the clinician in diagnosis. Current guidelines for radiological measurement state that these prevertebral soft tissues should not exceed 5mm at the midvertebral level of C3 and 20mm at C7. A ratio between soft tissue measurements and the width of the corresponding vertebra has also been championed as this takes into account magnification errors and variation in patient body habitus. Soft tissue measurements greater than 30% of the upper cervical vertebral bodies and greater than 100% of the lower cervical vertebral bodies are considered to be abnormal. The aim of this study was to assess reliability of current radiological guidelines on soft tissue measurement. A review of 200 consecutive normal lateral soft tissue cervical spine radiographs was undertaken. Patients were included if they were immobilised for blunt trauma and were aged 18 or older. Each patient included had cervical pathology excluded by a combination of clinical examination, flexion-extension views, CT and or MRI. Exclusion criteria included those patients with pre-existing cervical or retropharyngeal pathology, those who had been intubated or had a nasogastric tube passed. Two reviewers independently assessed soft tissue and bony widths at C3 and C7 using the PACs Software. All measurements were taken at the mid vertebral level, not at the end plates to ensure any anterior osteophytes did not create a falsely wide measurement. Plane film radiographs of 107 males and 93 females were included with an average age of 53. At the C3 level, mean soft tissue widths were 4.7mm ± 0.84mm SD and ranged from 2.7 to 7.4mm. The mean soft tissue width at C7 was 14.4mm ± 2.8mm SD with a range of 7.1 to 21.0 mm. Our results show 21.5% (43/200) of the patients exceeded the 5mm upper limit and 20% (40/200) exceeded the soft tissue to vertebra ratio at C3. Only 1% (2/200) of patients exceeded the upper limit of 20mm at C7 and only 2% (4/200) exceeded the soft tissue to vertebra ratio. The C3 guideline for maximum soft tissue widths has a poor specificity (78.5%) and the soft tissue to vertebral ratio at this level may also lead to further unnecessary investigation, as it too has a specificity of only 80%. However, the guidelines for PVST measurements at C7 are much more reliable with a specificity of 99.5% for the absolute measurement and 99% for the soft tissue to vertebra ratio. The ratio measurement has not conferred any significant diagnostic benefit over the static measurement. Current guidelines overestimate injuries at the C3 level but seem appropriate at the C7 level. There is no major benefit to using a ratio measurement over an absolute value

Patients with spinal injuries are very vulnerable to early complications or secondary spinal cord injuries before and during transfer, which may delay their rehabilitation. We designed transfer guidelines following concerns raised in a pilot study of the transfer of 16 patients. We then examined the effectiveness of the guidelines in 100 consecutive patients and completed the cycle by re-auditing a further 254 consecutive admissions after incorporating changes from the initial audit. The transfer guidelines addressed ten areas of clinical concern. We recorded a 50% improvement in airway monitoring and management. There was also improvement in anti-ulcer therapy and thromboprophylaxis (from 50% to 96%). We saw a 50% improvement in the use of appropriate support staff during the transfer. The re-audit showed that initial improvements were maintained and further improvements were noted in the transfer of relevant documentation and investigations. Improvement was also noted in the use of a vacuum mattress for the transfer of spinal injury patients and subsequently reduced incidence of pressure sores by a statistically significant level, which helped in the early rehabilitation of these patients. The majority of transfers were safe. The transfer guidelines were easy to use and improved patient care by ensuring that common problems had been addressed before and during transfer. This system reduced the risk of preventable complications during inter-hospital transfer. There may be wider application of similar guidelines to other trauma patients who require inter-hospital transfer, where there is a possibility of preventable secondary injury

Developmental dysplasia of the hip (DDH) is the commonest musculoskeletal condition diagnosed in neonates. Two previous studies showed no statistical advantage with the addition of ultrasound to clinical screening. In the UK, the Standing Medical Advisory Committee (SMAC) (1969) recommended clinical examination at birth and at 6 weeks. The Newborn Infant Physical Examination (NIPE) (2008) guidelines in addition advised ultrasound scanning for clinically unstable hips or for those with risk factors (breech presentation or family history). We compared SMAC and NIPE in the two main hospitals of the East Lancashire Hospitals NHS Trust: Burnley General Hospital (BGH) and the Royal Blackburn Hospital (RBH), respectively. Our outcome measure was the number of irreducible hip dislocations over a two year period (2007–2008). The records of the lead Paediatric Orthopaedic Surgeon were used to identify all cases of irreducible hip dislocations born in 2007 and 2008. Maternity records provided information on birth statistics. Syndromal cases were excluded from further analysis. BGH had 5382 live births and 7 irreducible hip dislocations (incidence 1.3/1000 births). 4/7 met SMAC recommendations and 6/7 met NIPE guidelines. 2/7 had equivocal clinical examinations at birth. 13 children were referred to the clinic with unstable hips (2.42/1000 births). RBH had 7899 total births and 3 irreducible hip dislocations (incidence 0.38/1000 births). 2/3 met NIPE guidance and 1/3 met SMAC recommendations. 33 were referred to the clinic with unstable hips (4.18/1000 births). The difference in the numbers of irreducible hips did not reach statistical significance (p=0.12). This study found no statistically significant advantage with the addition of selective ‘at risk’ ultrasound screening to clinical screening alone. Confounding factors in this study included the age of referral of cases to clinic and the numbers of cases referred as primary instability. These findings are in keeping with two previous studies in Norway

The goals of evidence-based clinical practice guidelines in medicine are to promote best practices and reduce variations. Ideally they should improve physician performance and patient outcomes. Although controversy exists about the definition of a high quality guideline and how guidelines will be used in our health care system, there is a call for their use to help improve quality patient care. Guidelines related to musculoskeletal topics should be developed by national orthopaedic organisations and subspecialty societies using the best available clinical evidence. The American Academy of Orthopaedic Surgeons has, since 2007, developed nine evidence-based guidelines in the areas of hand, sports, foot/ankle, shoulder, paediatrics and total joint replacement. The keys to successful guideline development include an expert methodologist, an experienced evidence analysis staff, strict adherence to established rules to minimise bias, and strong communication with relevant subspecialty societies. The AAOS process allows any individual or group to submit a potential topic for consideration. A physician workgroup of 5-8 members is selected after wide advertisement of the topic. Workgroup members must have no relevant financial conflicts of interest to the topic and are required to fill out an enhanced disclosure form. The workgroup is comprised of orthopaedic surgeons and other specialists with expertise in the topic. There are two in-person meetings between which the staff finds and analyses the data to support the specific initial questions. The final document is 300-350 pages. There is a period of peer review by relevant societies as well as a period of public commentary followed by the formal committee and Board approval. The final guideline is disseminated widely via press releases, subspecialty societies, AAOS meetings, webinars, JBJS, JAAOS, and related questions on resident and member national examinations. These guidelines now form the basis for future AAOS quality initiatives

The administration of prophylactic antibiotics is essential in the prevention of surgical site infection, particularly when metalwork is implanted. Intravenous Cefuroxime has been the antibiotic of choice for prophylaxis in our unit over the last few years. Unfortunately this has been linked to an increased rate of Clostridium Difficile infection. Our departmental antibiotic prophylaxis guidelines, based on the Scottish Intercollegiate Guidelines Network (SIGN), were therefore revised, such that intravenous Flucloxacillin and Gentamicin became the first line agents. We primarily aimed to assess whether prophylactic antibiotics were being administered according to our revised local guidelines. Steps were then taken to improve adherence to the guidelines, and the audit repeated. Data was collected prospectively between 1. st. November 2010 and 28. th. November 2010 (cycle 1). Demographic data, type of surgery, details of choice, dose and timing of antibiotic administration were compiled. The quality of documentation was also reviewed. Interventions to improve adherence to the guidelines were commenced between 1. st. January 2011 and 28. th. February 2011. This included a departmental presentation, supplementary distribution of the guidelines and email communication to all orthopaedic surgeons and anaesthetists to increase awareness. A repeat audit cycle was performed between 1. st. March 2011 and 28. th. March 2011 (cycle 2). All data was stored and statistically analysed using SPSS for Windows 17.0. A total of 130 patients were included, with 65 patients in each cycle. Demographic data and type of surgery were reasonably similar in both cycles. Intravenous antibiotics, when required, were administered within 30 minutes of the surgical incision in most cases in both cycles of the audit. In the first cycle of the audit only 9 out of 65 patients (14%) received the correct antibiotics as suggested by our updated guidelines. This improved significantly to 46 out of 57 patients (81%) in the second cycle. Documentation of antibiotic prescribing in the anaesthetic record, operation note and drug charts also improved in the second cycle. We observed poor initial adherence to our updated guidelines as most patients received incorrect antibiotic prophylaxis. However, following our audit interventions to increase awareness of the new guidelines, we witnessed a significant improvement in compliance. Our next step will be to ensure that the new policy of using intravenous Flucloxacillin and Gentamicin does indeed reduce the rate of Clostridium Difficile infection while maintaining a low rate of deep and superficial wound infection

To discover whether orthopaedic surgeons follow the BOA guidelines for secondary prevention of fragility fractures, a retrospective audit on neck of femur fractures treated in our hospital in October/November 2003 was carried out. There were 27 patients. Twenty-six patients (96%) had full blood count measured. LFT and bone-profile were measured in 18 patients (66%). Only nine patients (30%) had treatment for osteoporosis (calcium and vitamin D). Only one patient was referred for DEXA scan. Steps were taken to create better awareness of the BOA guidelines among junior doctors and nurse practitioners. In patients above 80 years of age it was decided to use abbreviated mental score above 7 as a clinical criterion for DEXA referral. A hospital protocol based on BOA guidelines was made. A re-audit was conducted during the period August-October 2004, with 37 patients. All of them had their full blood count and renal profile checked (100%). The bone-profile was measured in 28 (75.7%) and LFT in 34 (91.9%) patients. Twenty-four patients (65%) received treatment in the form of calcium + Vit D (20) and bisphosphonate (4). DEXA scan referral was not indicated in 14 patients as 4 of them were already on bisphosphonates and 10 patients had an abbreviated mental score of less than 7. Among the remaining 23 patients, nine (40%) were referred for DEXA scan. This improvement is statistically significant (p=0.03, chi square test). The re-audit shows that, although there is an improvement in the situation, we are still below the standards of secondary prevention of fragility fractures with 60% of femoral fragility fracture patients not being referred for DEXA scan. A pathway lead by a fracture liaison nurse dedicated to osteoporotic fracture patients should improve the situation

In August 2007 NICE issued its guidance for the treatment of patients with knee osteoarthritis (OA) with arthroscopic lavage. The recommendations stated that referral for arthroscopic lavage and debridement should not be offered as part of treatment for osteoarthritis, unless the person has osteoarthritis with a clear history of ‘mechanical locking’ (not gelling, giving way, or x-ray evidence of loose bodies). The aim of this study was to assess both the application of these guidelines over a four month period and whether this procedure had improved symptoms at first follow-up. This was a retrospective review from August-December 2011. The total number of arthroscopies performed during this period was obtained from theatre records. Further data was obtained through the hospital's electronic database. The diagnosis of OA was made through the analysis of referral and clinic letters, plain radiographs, MRI reports and operation notes. Only those patients with persisting OA symptoms were included, those with OA and recent history of injury or trauma were excluded. During this time period, 222 knee arthroscopies were performed in total, 99 were identified with persistent OA symptoms. Having identified these patients, referral letters were further analysed to identify the initial presenting symptom. Of the 99, 50 presented with pain, 28 presented with pain plus another symptom other than locking e.g. stiffness/swelling/giving-way, 21 presented with pain plus mechanical locking. According to current guidelines only these 21 patients should have been offered arthroscopic lavage as a form of treatment. In addition to these findings we identified what procedures had been carried out during arthroscopy for each symptom. Of those presenting with pain, 82% had a washout and debridement, 8% had washout, 4% had partial medial meniscectomy, 4% had lateral patellar release and 2% had partial lateral meniscectomy. Those with pain plus other symptoms not including locking, 82% had washout and debridement, 11% had partial medial meniscectomy, and 7% had a washout. Of those presenting with pain plus mechanical locking, 81% had washout and debridement and 19% had partial medial meniscectomy. Following the procedure, we analysed the outcome of symptoms at first-follow up. The mean follow-up time was 8 weeks. Of those presenting with just pain, 44% showed improvement, 52% had no change/on-going symptoms, 2% were unknown. Of those with pain plus other symptoms other than locking, 57% showed improvement, 35% had no change/on-going symptoms, 8% unknown. Of those with pain plus mechanical locking, 80% showed improvement, 10% had no change/on-going symptoms, 10% unknown. The results of this study support the current evidence that unless there are clear mechanical symptoms of locking, the use of arthroscopy in arthritic knee joints should be judicious and the reasons should be clearly documented

Introduction. ‘VTE disease is the new MRSA’, with much attention received in the media and the political world. Following the 2010 NICE guidelines all patients admitted to hospital should have VTE prophylaxis considered and a formal VTE risk assessment done with documentation and review in a 24 hour period. We carried out a completed audit cycle to identify our adherence to these guidelines and introduced a novel method to ensure compliance. Materials/Methods. An audit of 400 patients admitted to the orthopaedic department was carried out with review of case notes. Three key parameters were investigated: Firstly the compliance of carrying out a risk assessment for VTE disease with correct documentation, secondly investigating how many patients got re-assessed in 24 hours and finally if patients received appropriate VTE prophylaxis. The data was re-audited following the introduction of a new drug chart with a box section for VTE risk assessment and prophylaxis on the chart itself. Results. In the first cycle VTE risk assessments were carried out in 2.5% with 0% having a re-assessment in 24 hours and 93.5% of patients having correctly prescribed VTE prophylaxis. Following the new drug charts, the risk assessments were carried out in 79%, re-assessment in 50% and correct prescribed prophylaxis in 99% of the patients. Conclusions. We recommend all hospitals should have a section in the drug chart itself for VTE risk assessment and prophylaxis as this greatly improves compliance to the NICE guidelines. This ensures optimal patient care and protects the trust from litigations

Background:. Until recently, there has been no consensus of the best approach to dIfferentiating aseptic from septic loosening in joint replacement patients. The recent AAOS Clinical Practice Guideline Summary that was published in 2010, tasks orthopedic surgeons with the strong recommendation of obtaining ESR and CRP for all patients needing hip and knee arthroplasty revision surgery and aspirating the joint based upon these results. The purpose of this study is to determine from our patients whether this guideline has been helpful and cost effective in determining periprosthetic joint infections. Methods:. We retrospectively reviewed charts of 50 consecutive patients who underwent revision total hip or knee arthroplasty. Each patient received an ESR and CRP level prior to operation and patients with known periprosthetic joint infections were excluded from the study. As guidelines recommend, aspiration with cultures and cell count were obtained on all knees with either elevated ESR or CRP and all hips with both ESR and CRP elevated. We then determined how many patients needing revision arthroplasty of the hip or knee benefited from ESR, CRP, and aspiration by finding subclinical periprosthetic infection and changing the intraoperative treatment. Hospital charge data was used to report cost of this protocol. Results. Sixty-four percent (32/50) patients had elevated ESR and/or CRP. Eighteen patients (12 hips; 7 knees) required joint aspirations per the guidelines. None of the aspirations were positive for bacterial growth. The total hospital charges for aspiration and cultures in this patient population were $81, 712.44. No sub clinical infection was identified. Conclusion:. Although guidelines may more readily diagnose every case of subclinical joint infection, we must continue to evaluate the cost of this type protocol in a busy revision practice

There were 70000 people admitted to hospital with fractured hips in 2007 and the incidence is rising by 2% each year. Hip fractures represent significant morbidity and mortality to patients and cost the NHS £1.8 billion annually. In 2008 the British Orthopaedic Association Standards for Trauma (BOAST) issued a 14-point guideline to be followed for the management of hip fractures. The aim was to improve secondary prevention of osteoporosis, reduce the falls risk and further fractures. This aimed to provide better care to improve the outcomes for patients and reduce the burden of hip fractures on society. The aim of the audit was to see if the BOAST guidelines are met before and after the transition to a level 1 MTC (Major Trauma Centre) and to measure any impact the change had. Methods: Prospective data was collected for three months in 2010, 2011 and 2012. 94 case notes were reviewed and compared to the outcomes laid out in the BOAST guidelines to see if standards were met. Overall adherence to the guideline's recommendations was high throughout the 3 sample months. For each of the 3 sample months 100% adherence was seen in all of the following criteria: further imaging if x-rays unclear, appropriate analgesia, pre-op assessment, seniority of surgeon, orthogeriatrician involvement, seniority of surgeons and submission to the National Hip Fracture Database. The main common area where adherence was less than 100% was with A and E breaches (i.e. greater than 4 hours referral to the ward). Despite relocation and transition to a level 1 MTC, the management of fractured neck of femur patients compared to the BOAST guidelines remained of a high standard. Further improvements have also been made since moving to the new hospital site where shortcomings in management have been identified. Improvements from year one to three include prophylactic antibiotics and warfarin reversal; there is now a new trust protocol in place for warfarin reversal in the case of hip fractures. Elsewhere adherence to the guidelines remains high across the sample months. Confirming that despite moving to a level 1 status the trauma team continues to be performing well and managing this group appropriately. In January 2012 BOAST published a second version of the hip fracture guidelines: A and E breaches were removed from the guidelines. There have also been several new additions to the guidelines, which prompt a further re-audit in the future

Implant choice was changed from cemented Thompson to Exeter Trauma Stem (ETS) for treatment of displaced intra-capsular neck of femur fractures in University Hospital Aintree, Liverpool, United Kingdom (a major trauma center), following the NICE guidelines that advised about the use of a proven femoral stem design rather than Austin Moore or Thompson stems for hemiarthroplasties. The aim of our study was to compare the results of Thompson versus ETS hemiarthroplasty in Aintree. We initially compared 100 Thompson hemiarthroplasties that were performed before the start of ETS use, with 100 ETS hemiarthroplasties. There was no statistically significant difference between the two groups in terms of patients' demographics (age, sex and ASA grade), intra-operative difficulties/complications, post op medical complications, blood transfusion, in-patient stay and dislocations. The operative time was statistically significantly longer in the ETS group (p= .0067). Worryingly, the 30 days mortality in ETS group was more than three times higher in ETS group (5 in Thompson group versus 16 in ETS group. P= .011). To corroborate our above findings we studied 100 more consecutive patients that had ETS hemiarthroplasty. The results of this group showed 30 day mortality of 8 percent. However the operative time was again significantly longer (p= .003) and there was 18 percent conversion to bipolar hemiarthropalsty. Moreover there was statistically significant increased rate of deep infection (7%, p = .03) and blood transfusion (27%, p = .007). This we feel may be due to longer and more surgically demanding operative technique including pressurised cementation in some patients with significant medical comorbidities. Our results raise the question whether ETS hemiarthoplasty implant is a good implant choice for neck of femur fracture patients. Randomised control trials are needed to prove that ETS implant is any better than Thompson hemiarthroplasty implants in this group of patients

NICE published the guidelines ‘Selection of prostheses for primary hip replacement’ in 2000. Essentially these guidelines made two recommendations: firstly to use prostheses which had attained the ‘10 year benchmark’ of a revision rate of 10% or less at 10 years, or had a minimum of three years revision rate experience that was on target to reach this benchmark; and secondly to use cemented hip prostheses to the exclusion of uncemented and hybrid prostheses. The information from the Trent Regional Arthroplasty Study (TRAS) has been used to retrospectively examine the types of hip prostheses used from 1990 – 2005, and assess the impact that the NICE guidelines have had on orthopaedic practice. This study revealed that the percentage of prostheses used which attained the ‘ten year benchmark’ has increased since the guidelines were published. In 2001, of the ten cups, which constituted 80% of the acetabular components used, only three attained this NICE benchmark, but by 2005 this number had risen to eight. Similarly in 2001, of the eight stems, which constituted almost 80% of the femoral components used, only five attained this NICE benchmark. In 2005 seven out of these eight stems had attained the minimum standard. However contrary to the recommendation made by NICE in 2000, to use cemented prostheses, the results indicate the use of uncemented prostheses has trebled (from 6.7% to 19.2%, n= 137 and 632 respectively), and the use of hybrid prostheses has more than doubled (from 8.8% to 22% of all prostheses, n= 181 and 722 respectively) since the guidelines were published. Therefore the recommendations made by NICE are not being followed, which calls the value of NICE guidelines into question
