The purpose of the present study is to determine the incidence, location and rate of VTE following routine mechanical, chemical prophylaxis in trauma/elective patients and to understand what factors are responsible for the continuing high frequency of thromboembolic complication despite the fact that low molecular-weight heparin (LMWH) is now widely used for prophylaxis. All of the inpatients at the orthopaedics ward, Princess Alexandra Hospital (level one trauma centre, Brisbane) between the first May 2009 and 30th of April 2010 with the diagnosis of DVT/PE were included in this study. Patients were chosen based on the diagnosis of DVT with ultrasound or PE with CTPA during their admission in this period which was performed whenever clinical signs indicated DVT or PE. 64% of the included patients had DVT and 42% had PE which was developed during their admission. Included patients had a mean age ±SD age of 56years ± 23 years, 68% were men and 72% suffered trauma. The 18% of patients had previous history of PE or DVT. The incidence of VTE was significantly higher in men at ages between 20–40 .29% of the patients had ICU admission during their stay in hospital. 28%had spinal cord injury, 21%with head trauma, and 36%with multiple bone fractures. Most of the patients had lower limb injury or operation and just one patient was with isolated upper limb injury. The mean period of hospitalization for the included patients were 29 ± 19 days (range, 6–77). DVTs occurred 8 days ± 7 days(range, 1–31) post admission. PEs occurred 10 days ± 8 days (range, 3–30) after admission. Location of DVT was available for 14 patients: 9 (64%)lower and 6 (43 %)upper, with one(0.07%)having both. Twelve of 28 patients with VTE were started on prophylactic clexane (40mg once daily), and six patients were on heparin(5000 unit twice daily). All of the patients with PE had lower limb injury. Considering the number of orthopaedics ward patients during our study period our data show the incidence of VTE in one year is lower than that of literature and the common standard prophylaxis with early mechanical prophylaxis after admission and following pharmacological prophylaxis when it is safe has acceptable results.
In the study group only 1 patient needed prolonged high dose anticoagulant treatment while 6 patients in the enoxaparin group were treated (p=0.020). The cumulative incidence of adverse events in the study group was significantly lower than that observed in the control group (p=0.000). Average postoperative hospital stay was 8.4 days in the study group and 11.7 days in the control group (p=0.002). The CECT device was very well tolerated by the patients and facilitated early mobilization.
The incidence of deep-vein thrombosis and the need for thromboprophylaxis following isolated trauma below the knee is uncertain. We have investigated this with a prospective randomised double-blind controlled trial using

Total Joint Arthroplasty (TJA) is a successful orthopaedic procedure allowing dramatic clinical and functional improvements. Globally, there's been an increase in demand and performed cases associated with an increase in complications. Subsequently, focus on the prevention of complications has become important worldwide. The incidence of venous-thrombolic events (VTE) despite great attention has not diminished despite much investigation. A balance between efficacy and safety from the available agents is essential.
Postoperative leg swelling after a total knee replacement is common complaint amongst patients. We studied leg swelling by constructing a novel, simple and cost water volumeter. A pilot study was conducted on 15 volunteers by two observers and each observer took a total of three readings. The mean intraobserver variation was 0.2 percent and mean interobserver variation was 0.3 percent, indicating a highly acceptable level of accuracy. The water volumeterwas then used in a randomized prospective study was conducted to determine the relationship between postoperative leg swelling and Fraxiparine, a

Introduction: Currently patients who had undergone lower limb arthroplasty are discharged a few days after surgery, at which stage they still need anticoagulation treatment. The transition from hospital to the community is a sensitive period and is susceptible to mistakes and misunderstandings. Patients may underestimate the importance of the continuing treatment and their inconvenience to self-administrate subcutaneous treatment might decrease their compliance. The purpose of this prospective cohort study was to investigate the continuity of the treatment with subcutaneous
We report an audit of 208 patients with a mean age of 39 years (16 to 65) attending the Orthopaedic Assessment Unit at the Wellington Hospital between January 2006 and December 2007 with an injury of the tendo Achillis requiring immobilisation in a cast. Information on assessment of venous thromboembolism (VTE) risk, prophylactic measures and VTE events for all patients was obtained from the medical records. A VTE risk factor was documented in the records of three (1%) patients. One of the 208 patients received aspirin prophylaxis; none received
Thromboprophylaxis after elective orthopaedic surgery remains controversial. Recent guidelines from the National Institute for Clinical Excellence (NICE) have suggested that
Thrombelastography (TEG) is a point-of-care tool that can measure clot formation and breakdown using a whole blood sample. We have previously used serial TEG analysis to define hypercoagulability and increased venous thromboembolism (VTE) risk following a major fracture requiring surgical treatment. Additionally, we have used serial TEG analysis to quantify the prolonged hypercoagulable state and increased VTE risk that ensues following a hip fracture. Recently developed cartridge-based platelet mapping (PLM) using TEG analysis can be used to activate platelets at either the adenosine diphosphate (ADP) receptor or at the Thromboxane A2 (AA) receptor, in order to evaluate clot strength when platelets are activated only through those specific receptors. This study aim was to evaluate platelet contribution to hypercoagulability, in order to identify potential therapeutic targets for VTE prevention. We hypothesized that there would be a platelet-predominant contribution to hypercoagulability following a hip fracture. Patients aged 50 years or older with a hip fracture treated surgically were enrolled in this prospective cohort study. Exclusion criteria were: prior history of VTE, active malignancy, or pre-injury therapeutic dose anticoagulation. Serial TEG and PLM analyses were performed at admission, post-operative day (POD) 1, 3, 5, 7 and at 2-, 4-, 6- and 12-weeks post-operatively. All patients received thromboprophylaxis with
Introduction. The use of intramedullary lengthening devices is becoming increasingly popular. There are no published data regarding the incidence of venous thromboembolism following intramedullary lengthening and no reports or guidance for current practices on use of thromboprophylaxis. Following a case of post-operative deep vein thrombosis in our institution, we felt that it is important to assess best practice. We conducted this survey to collect data that would describe current practice and help guide consensus for treatment. Materials and Methods. We have identified surgeons across the UK that perform intramedullary lengthening through the British Limb Reconstruction Society membership and a Precise Users database. Surgeons were contacted and asked to respond to an online survey (SurveyMonkey - SVMK Inc.). Responses to thromboprophylaxis regimes employed in their practice and cases of venous thromboembolism were collated. Results. 24 out of 54 surgeons identified responded with a total of 454 cases of intramedullary lengthening (352 femoral and 102 tibial nails) performed over the last 5 years. Only one case of DVT following femoral lengthening was reported. There is wide variability in practice both in terms of thromboprophylaxis risk assessment, choice of medications (20% no pharmacological treatment, 75%
Major orthopaedic fractures are an independent risk factor for the development of venous thromboembolism (VTE), which are significant causes of preventable morbidity and mortality in trauma patients. Despite thromboprophylaxis, patients who sustain a pelvic or acetabular fracture (PA) continue to have high rates of VTE (12% incidence). Thrombelastography (TEG) is a whole-blood, point-of-care test which provides an overview of the clotting process. Maximal amplitude (MA), from TEG analysis, is the measure of clot strength and values ≥65mm have been used to quantify hypercoagulability and increased VTE risk. Therefore, the primary aim was to use serial TEG analysis to quantify the duration of hypercoagulability, following surgically treated PA fractures. This is a single centre, prospective cohort study of adult patients 18 years or older with surgically treated PA fractures. Consecutive patients were enrolled from a Level I trauma centre and blood draws were taken over a 3-month follow-up period for serial TEG analysis. Hypercoagulability was defined as MA ≥65mm. Exclusion criteria: bleeding disorders, active malignancy, current therapeutic anticoagulation, burns (>20% of body surface) and currently, or expecting to become pregnant within study timeframe. Serial TEG analysis was performed using a TEG6s hemostasis analyzer (Haemonetics Corp.) upon admission, pre-operatively, on post-operative day (POD) 1, 3, 5, 7 (or until discharged from hospital, whichever comes sooner), then in follow-up at 2-, 4-, 6-weeks and 3-months post-operatively. Patients received standardized thromboprophylaxis with

Venous thromboembolism (VTE) prophylaxis following total joint arthroplasty (TJA) should be individualised in order to maximise the efficacy of prophylactic measures while avoiding the adverse events associated with the use of anticoagulants. At our institution, we have developed a scoring model using the Nationwide Inpatient Sample (NIS) database, which is validated against our institutional data, to stratify patients into low- and high-risk groups for VTE. Low-risk patients are placed on aspirin 81 mg twice daily for four weeks post-operatively, and high-risk patients are placed on either a Vitamin K antagonist (warfarin),
According to the National Institute of Clinical Excellence (NICE) Guidelines, some foot and ankle patients are, by definition, at high risk of DVT/PE. Despite NICE guidance, DVT recommendations are still controversial, and are being reviewed by the BOA to be more operation and context specific. One consultant at our institution therefore initiated a 6 week medical DVT prophylaxis regimen for all his post-operative hind–foot surgery patients who were placed in plaster. From January 2007 to February 2008 we audited 97 hind-foot patients to measure their compliance rate, complications and DVT/PE rate. Compliance was excellent (97%) particularly with regard to

Despite increasing scientific investigation, the best method for preventing post-operative deep vein thrombosis remains unclear in patients undergoing a total hip replacement. In the wake of the recent controversial National Institute for Health and Clinical Excellence Clinical Guidelines on the prevention of thrombo-embolism, we felt it was timely to survey current Scottish Surgeons thrombo-prophylactic practice when performing total hip replacements. E-mail questionnaires were sent to all Scottish Orthopaedic consultants. They were asked about routine pharmacological and mechanical prophylaxis in patients undergoing total hip replacement. Comparison was made with a previous survey done in 2003. The response rate was 75%. The survey showed an increased use of pharmacological prophylaxis from 93% to 100%. This was due to the increased use of aspirin, from 51% to 64%. The use of

Introduction. There are no specific and clear guidelines regarding management of trauma patients who are on Warfarin. The objective of this study was to compare two methods of anticoagulation management in the pre-operative period for this group. Methods. This study was conducted in two phases. In the first half (October 2005 to April 2006) the trauma patients on Warfarin were managed by the traditional method. The second group of patients who were admitted during May to December 2006 was given a single stat dose of Vitamin K (1 mg IV) in addition to stopping Warfarin and starting
It is widely recognised that pelvic disruption in association with high-energy trauma is a life-threatening injury. The potential morbidity and mortality associated with acetabular injuries are less well understood. Due to chronic underfunding and the absence of a comprehensive and coordinated national approach to the management of acetabular trauma throughout the UK, patients can incur prolonged recumbency. Prompt and appropriate referral for specialist management, thromboprophylaxis and venous thrombosis surveillance are important issues for the referring centre. We performed a postal questionnaire to establish the current clinical practice in the specialist centres throughout the UK in pelvic and acetabular trauma, with respect to time to surgery, thromboprophylaxis, and surveillance. We identified twenty-one units and thirty-seven surgeons in the NHS who deal with pelvic and acetabular injuries. The mean time to surgery from injury in the UK is 8.5 days (range 2-19 days). The larger units that accept and treat patients from outside their region experience the greatest delay to surgery. Mechanical thromboprophylaxis was used in 67% (14) of the units. 24% (5) use arterio-venous boots, 19% (4) use calf pumps, and 52% (11) use TEDS stockings. No unit routinely use prophylactic IVC filters in acetabular trauma. Chemical thromboprophylaxis is routinely used in 100% (21) of the units. 95% (20) used prophylactic doses of unfractionated

Introduction:. The National institute of Health and Clinical Excellence (NICE) guidelines for thromboprophylaxis following lower limb surgery and plastercast immobilisation recommend pharmacological prophylaxis be considered until the cast is removed. These guidelines have been extrapolated from data for hip and knee arthroplasty, and trauma studies. Recent studies have questioned the validity of these guidelines. At Portsmouth,
Most of current literatures advise on thromboprophylaxis with injectable LMWH for trauma patients. Injectable anticoagulants have got inherent problems of pain, bruising and difficulty in administering the drug, which leads to low compliance. Clexane is derived from a pig's intestinal mucosa, hence could be objectionable to certain proportion of patients because of their religious beliefs. Oral anticoagulants have been used as thromboprophylactic agents in hip and knee arthroplasty. However there is not enough literature supporting their use as thromboprophylactic agent in ambulatory trauma patients with ankle fracture being managed non-operatively as out-patient. This study looks into the efficacy of oral anticoagulant in preventing VTE in ambulatory trauma patients requiring temporary lower limb immobilisation for management of ankle fracture. The end point of this study was symptomatic deep vein thrombosis (either proximal or distal) and pulmonary embolism. Routine assessment with a VTE assessment risk proforma for all patients with temporary lower limb immobilisation following lower limb injury requiring plaster cast is done in the fracture clinic at this university hospital. These patients are categorised as low or high risk for a venous thromboembolic event depending on their risk factor and accordingly started on prophylactic dose of oral anticoagulant (Rivaroxaban - Factor Xa inhibitor). Before the therapy is started these patients have a routing blood check, which includes a full blood count and urea and electrolyte. Therapy is continued for the duration of immobilisation. Bleeding risk assessment is done using a proforma based on NICE guideline CG92. If there is any concern specialist haematologist advice is sought. A total of 200 consecutive patients who presented to the fracture clinic with ankle fracture, which was managed in plaster cast non-operatively, were included in this study. They were followed up for three months following injury. This was done by checking these patients’ radiology report including ultrasound and CT pulmonary scan (CTPA) test on hospital's electronic system. Fracture of the lateral malleolus which include Weber-A, Weber-B and Weber-C fractures were included in the study. Also included were bimalleolar fractures and isolated medial malleolus fractures. Complex pilon fractures, polytrauma and paediatric patients were excluded from the study. Only one case of plaster associated isolated distal deep vein (soleal vein) thrombosis was reported in this patient subgroup. There was no incidence of proximal deep vein thrombosis or pulmonary embolism. No significant bleeding event was reported. Injectable

Aims: To present our experience from the diagnosis and treatment of axillary vein thrombosis in seven cases. Methods: We reviewed the medical records and x-rays of all the patients who were admitted and treated for axillary vein thrombosis (AVT) in the Orthopaedic and Vascular Surgery Departments of our hospital between 1995 and 2001. Results: We reviewed seven patients (þve males and two females, mean age 52.3 years old) presented in our hospital with AVT. Two of these cases occurred following musculoskeletal injuries (extrinsic trauma), three after central line insertion for oncological treatment (intrinsic trauma), one was related to the oral contraceptive pill (thrombophilic tendency) and one case was effort related (Paget-Schroetter syndrome). Clinically there was plethoria, arm swelling and persistent superþcial veins which were aggravated with activity and dependency. Venography or Duplex scan was used to establish the diagnosis. Causing factors and associated morbidity were assessed and treated. All of the cases of vein thrombosis responded well to conservative treatment (heparin/

Objective To survey current antithrombotic prophylaxis regimes of foot and ankle surgeons in the UK, and their self-reported rates of deep vein thrombosis (DVT) and pulmonary embolism (PE). Method A postal questionnaire was sent to 180 members of the British Orthopaedic Foot and Ankle Society requesting regime and types of antithrombotic prophylaxis (if any) used for elective forefoot, elective midfoot, open elective ankle, elective ankle arthroscopy and ankle trauma surgery, and numbers of cases of DVT and PE. Results Ninety surgeons responded (50%). Surgeons had been practising as consultants with a special interest in foot and ankle surgery for an average of 8.9 years, and performed an average of 24 foot and ankle cases per month. Ten per cent never used antithrombotic prophylaxis in foot and ankle surgery, 64/90 used it routinely for certain cases, and 17/90 used it routinely in all patients. The most common types of prophylaxis were

Aim: To identify the local and systemic morbidity of simultaneous sequential bilateral total knee arthroplasty in a large patient population and to undertake a comparative statistical analysis with a group of matched patients who underwent staged bilateral total knee replacement during the same period. Methods: Theatre records at two regional district general hospitals were scrutinised to identify all patients who had undergone simultaneous sequential and staged bilateral total knee arthroplasty over a three year period. Patient case notes and hospital charts were retrospectively reviewed to obtain several outcome measures to allow subsequent risk factor assessment. Results: 134 patients with 268 primary knee arthroplasties undergoing a simultaneous procedure were identified. The average age was 70 with a minimum follow up of 12 months. The study results revealed 1.5% mortality, 5.2% local complication and 14.9% systemic complication rates and this increased with age. During the same period 34 patients (68 knees) who had undergone staged procedures at least 3 months apart were also identified. Statistically significant findings between both groups included the reduced length of hospital stay, a 3-fold increase in the requirement for banked blood (particularly when either suction drainage or

Introduction. Pulmonary emboli (PE) after total hip and knee arthroplasties is an uncommon event. However, once it happens, it may results in sudden death. Thus, the prophylaxis of venous thromboembolism (VTE), including symptomatic deep vein thrombosis (DVT) and PE, is one of the challenging trials for Orthopaedic surgeons. Many procedures have been developed, e.g. early mobilization, compression stocking, intermittent pneumatic compression (IPC) devices, and anticoagulation agents. However, the most effective treatment for prophylaxis against VTE after the arthroplasties remains undecided. Recently, many
Thromboembolism following total hip arthroplasty is a common complication that may result in significant morbidity and mortality. Despite this, optimal prophylactic regimen is controversial. According to the literature, the prevalence of deep venous thrombosis during the early post-operative period ranges from 13% in patients utilizing
Background: Diagnostic and operative codes are routinely collected on every patient admitted to National Health Service (NHS) hospitals in England and Wales (hospital episode statistics, HES). The data allows for linkage of post-operative complications and primary operative procedures, even when patients are re-admitted following a successful discharge. Morbidity and mortality data on foot and ankle surgery (F&
A) has not previously been available in large numbers for NHS patients. Methods: All HES data for a 44-month period prior to August 2008 was analysed and divided into four groups – hindfoot fusion, ankle fracture surgery, ankle replacement and a control group. The control group was of first metatarsal osteotomy, which is predominantly day case surgery where no above ankle cast is used. The incidence of pulmonary embolism (PE) and all cause mortality (MR) within 90 days, and a return to theatre (RTT, as a complication of the index procedure) within 30 days was calculated for each group. Results: 7448 patients underwent a hindfoot fusion. PE, RTT and MR were 0.11%, 0.11% and 0.12% respectively. 58732 patients had operative fixation of an ankle fracture. PE, RTT and MR were 0.16%, 0.08% and 0.35%. 1695 patients had an ankle replacement. PE, RTT and MR were 0.06%, 0.35% and zero. 35206 patients underwent a first metatarsal osteotomy. PE, RTT and mortality rates were 0.02%, 0.01% and 0.03%. Discussion: There is controversy regarding the use of venous thrombo-embolic (VTE) prophylaxis in foot and ankle surgery. Non-fatal PE in F&

Assessing risk is a key skill for all surgeons, playing a vital role in such diverse settings informed consent, audit and surgical planning. We undertook this study to define what is an acceptable level of risk for orthopaedic surgeons undertaking lower limb arthroplasty in today's medicolegal climate. We surveyed all consultants and trainees registered with the NZOA and asked them what change in their complication rate would cause them to consider changing their practice. We also asked them how certain they would have to be that this change was real and not simply due to chance (the so-called “cluster effect”). The specific complications we considered were DVT/PE, dislocation of total hip replacement or deep infection in lower limb arthroplasty patients. This allowed us to calculate with 95% accuracy the levels of complication surgeons would deem unacceptable. Using Cochrane's criteria for statistically valid survey results we obtained a greater than 95% representative sample. From these responses we calculated levels of complication which would worry the “average” surgeon (median value), the “vast majority” (95%) of surgeons and a change in complication rate which would be required to satisfy “statistical significance” (i.e. the level set literature proof with p<0.05 and power of 0.8). When considering deep infection following hip or knee arthroplasty: using a baseline of 0.9% as an average published rate, the average surgeon would consider changing their practice if their rate reached 2.5% and 95% of surgeons would consider changing if their rate reached 5%. For hip dislocation the baseline was set at 2.5% with the average surgeon intervening if their rate rose to 4% and the vast majority of surgeons intervening at 10%. For fatal PE the baseline was given as 0.2% with the average surgeon auditing their practice at 0.8% and the vast majority of surgeons concerned with a rate of 2.2% or higher. No difference was found in consultant/trainee responses except in the reason given for use of thromboprophylaxis where consultants used it for prevention of fatal PE and registrars for non-fatal PE. These results could be used both as a potential guide for trainees and consultants in audit and also in guiding the use of, for instance, thromboprophylaxis where the “number needed to treat” for
Background:
Patients with a thrombotic history are thought to be at greater risk for developing blood clots following total hip arthroplasty (THA) or total knee arthroplasty (TKA). The incidence of venous thromboembolism and risk factors associated with clot development in this population of patients, however, are not well defined. From the years 2002 to 2008, 547 patients undergoing elective joint arthroplasty with a history of thrombotic disease, defined by prior history of deep venous thrombosis (DVT) or pulmonary embolism (PE), were followed prospectively for a minimum of one month after TKA or THA. Patients received prophylactic anticoagulation with coumadin starting on POD 1 with or without bridge therapy with
The incidence of DVT and need for thrombo-prophylaxis following isolated distal lower extremity fractures is unknown. The purpose of this study was to determine whether or not thrombo-prophylaxis with
Aim:. Enhanced recovery pathway is compromised by increased wound oozing due to chemical thromboprophylaxis increasing length of stay (LoS) and complications. We aimed to analyse the difference between LoS, VTE episodes, deep infection and return to theatre between matched cohort of patients either receiving combination therapy of Clexane followed by Rivaroxaban or Rivaroxaban only. Methods:. We retrospectively collected data on LoS of patients undergoing hip and knee replacements, The cohorts consisted of 458 THRs (235 group I & 223 group II and 526 TKRs (250 group I & 276 group II). Group I received Rivaroxaban. Age was not an exclusion criteria and matched in both groups. ASA 1 to stable ASA3 patients were included in the cohort. Included were patients on aspirin 75 mg PO which was not stopped pre-operatively in either cohort in equal numbers. Anaesthetic and perioperative management of the patients as part of our enhanced recovery protocols were the same for both groups. Multimodal pain management, antibiotic prophylaxis, same day mobilisation, flowtron calf pumps, TED stockings, preoperative MRSA screening was standardised and matched. For TKRs a standard medial parapatellar approach and THRs a standard posterolateral (Southern) approach were utilised. Patients did not have a drain insitu. Exclusion criteria was patients with malignancy, haematological co-morbidities, Hb below 11 and BMI greater than 40. All prosthesis used were standardised to cemented TKR, cemented THR or uncemented THR depending on bone quality at the time of surgery. Patients in first cohort (group I) received 10 mg Rivaroxaban at 8 hours post op and continued for 14 days for TKRs and 35 days for THRs. Patients in group II received Clexane 40 mg SC at 8 hours post op followed by Rivaroxaban at 24 hours after first dose of Clexane and continued daily for 14 days for TKRs and 35 days for THRs. Results:. LoS in group I was 3.52 days for THRs and 3.57 days for TKRs. LOS in Group II was 2.37 days for THRs and 2.52 days for TKRs. Return to theatre in group 1 was1.3% for THRs and 0% for TKRs. In Group II was 0.4% for THRs and 0% for TKRs. Deep infection in group I was 0.4% for THRs and 0.8% for TKRs. In Group II was 0%. VTE episodes was similar in both groups. These are statistically significant. Conclusion:. By using a combined use of Chemical VTE agents we halved our complications such as deep infection and helped in our enhanced recovery programme by reducing the LoS by one day whilst VTE events remained the same. The novel combination of administration of
Goals: In this study we analysed the patients admitted with orthopaedic problems who had coffee ground vomitus for incidence, risk factors, investigations and the management. This project was to highlight this significant but rather neglected problem and to draw up local guidelines in the prevention. Methods: This is a prospective study conducted for a period of six months from 1st of July 2005 to 31st of Dec 2005. All patients admitted with Orthopaedic problems who had coffee ground vomitus were included in the study after confirmation with haemoccult test. Their case notes were studied to identify the risk factors, preventive measures that could have been taken and their management. Results: There were 34 (2.3%) patients who had coffee ground vomitus, out of 1427 orthopaedic admissions during the study period. There were 14 (41%) men and 20 (59%) women. The mean age was 73.7 yrs in men and 82.2 yrs in women. This problem was more common in 8th decade with 15 patients (45.5%). There were 6 patients each in 7th and 9th decade, 5 patients in 6th decade and only 2 patients in 5th decade. There were 19 (55.5%) trauma admissions with fractures and 15 (45.5%) elective admissions. There were 12 (35.2%) patients with previous gastric problems. There were 20 (59%) patients who were on gastric irritant medications, out of which only 5 (25%) were on gastro protective medications. All 34(100%) patients were on

Introduction: Besides other techniques to reduce blood loss, the use of pneumatic tourniquet is commonly accepted in total knee arthroplasty (TKA). Furthermore it is used to maintain a clean and dry operative field to improve visualization, to use a better cementing technique, and to reduce operating time. The time of tourniquet release is discussed controversially in literature. However, there are only a few prospective randomised studies that compared the effect of timing of tourniquet release in cementless or cemented TKA. To our knowledge, this is the first study that investigated the influence of tourniquet release on blood loss in a randomized prospective study in simultaneous bilateral cemented TKA. Methods: 20 patients (40 knees) underwent simultaneous bilateral cemented TKA with the cemented Triathlon Knee System (Stryker) between February and May 2006. The mean age of the patients was 67 years (67+/−11 years). 7 males and 13 females were treated with TKA (mean tourniquet pressure: 282.5+/−33.5 mm Hg). In 20 patients one knee was operated with tourniquet release and hemostasis before wound closure (“Technique A”), and the other knee with tourniquet release after wound closure and pressure dressing (“Technique B”). To determine the order of tourniquet release technique in simultaneous bilateral TKA, the patients were randomized in two groups: “Group A” (20 knees) first knee with tourniquet release and hemostasis before wound closure, and “Group B” (20 knees) second knee with tourniquet release and hemostasis before wound closure. The patients were given

The selection of venous thromboembolism (VTE) prophylaxis after total joint arthroplasty (TJA) has been controversial. Although the aspirin controversy is presumably resolved, there is no medical evidence for the “optimal” VTE prophylaxis regime for individual patients. A risk-stratified multi-modal VTE prophylaxis protocol was developed and adopted by consensus. VTE risk factors and bleeding risk factors were categorised into six VTE/bleeding risk levels: (1) pre-operative vitamin K antagonists (VKA) use, (2) bleeding risk factors, (3) hypercoagulable state, (4) pre-operative anti-platelet therapy [clopidogrel use], (5) VTE risk factors, (6) no VTE or bleeding risk factors. The pharmacologic agents used for each risk level were: (1) resume VKA with
INTRODUCTION. Warfarin remains the treatment of choice for the majority of patients with venous thromboembolism, atrial fibrillation and valvular heart disease or valve replacement unless contraindicated. Poor management of patients on warfarin often leads to delay in surgery, life threatening bleeding during or after operation and unnecessary delay in discharge from hospitals in United Kingdom. METHODS. We carried out a prospective study on patients who were on warfarin and underwent elective and emergency orthopaedic procedures during period of study- August 2007 to April 2008. All patients included in the study were identified from admission notes during period of study. All data regarding indications for warfarin, pre and post procedures INR, elective or emergency orthopaedic procedures and complications were collected using a standard proforma. RESULTS. 18 patients, 12 male and 6 female were included into the study. Patients' age ranged from 47-87 with mean of 76. The indications for warfarin therapy were atrial fibrillation in 12 patients, deep vein thrombosis in 5 patients and left ventricular aneurysm in 1 patient. 18 procedures, 10 elective and 8 emergency orthopaedic procedures were carried out during period of study. Elective procedures - 7 primary joint arthroplasty, 1 revision hip arthroplasty, 1 removal of metalwork and 1 metatarsophalangeal joint fusion. Emergency procedures - 4 hip hemiarthroplasty, 2 dynamic hip screw fixation, 1 external fixator application and 1 open reduction and internal fixation of ankle. All elective admission patients were pre-assessed in clinic prior to admission and were advised to stop warfarin based on their INR level. Patients with INR 2-3 had their warfarin stopped 4 days prior to surgery while patients with INR 3-4.5 had their warfarin stopped 5 days prior to surgery. This group of patients had their INR check on admission and ranged from 1.1-1.5. This group of patients had no reversal therapy and no cancellations were made to their operation. 8 emergency admission patients had INR of 1.4-4.7 on admission with mean of 2.7. 5 patients had reversal therapy while 3 patients had no reversal therapy. Pharmacological methods used to reduce the INR were fresh frozen plasma in 1 patient and Vitamin K in 4 other patients. 2 patients that received reversal therapy had operation on day 1, 2 on day 3 and 1 on day 5. 1 patient that had no reversal therapy was operated on day 1, 1 on day 3 and 1 on day 5. Patient that received no reversal therapy and operated on day 5 of admission died post-operatively from medical complications. Mean delay for patient that had reversal therapy was 2.2 days compared to 3 days in patient with no reversal therapy. All patients in this study had prophylactic
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),
Introduction: There is a general conception in the orthopaedic community that blood loss/transfusion rate in hip resurfacing procedures is greater than that conventional Total Hip Arthroplasty (THA). The theoretical basis is that uncemented procedures leave large bleeding bone surfaces and that resurfacing arthroplasty needs larger incisions, greater exposure and more extensive soft tissue releases. Although this theory has gained informal. Acceptance in orthopaedic practice, there is little evidence in the literature to support this. Background The purpose of this study was to determine the actual blood loss and transfusion rate (including hidden blood loss) in a consecutive cohort of patients undergoing hip re-surfacing by a single surgeon using the Articular Surface Replacement (ASR – DePuy). Materials and Methods: The cohort consisted of 58 patients who were followed prospectively. All patients underwent a standardized surgical procedure performed by one senior surgeon. Hypotensive anaesthesia was used in all cases and surgery was via a standard posterior approach. Drains were not routinely placed, but if used, were removed within 24 hours.
Background. Hip fracture in the elderly has high morbidity and mortality. National guidelines have recommended
Transfusion after primary total hip arthroplasty (THA) has become rare, and identification of causative factors allows preventive measures. The aim of this study was to determine patient-specific factors that increase the risk of needing a blood transfusion. All patients who underwent elective THA were analyzed retrospectively in this single-centre study from 2020 to 2021. A total of 2,892 patients were included. Transfusion-related parameters were evaluated. A multiple logistic regression was performed to determine whether age, BMI, American Society of Anesthesiologists (ASA) grade, sex, or preoperative haemoglobin (Hb) could predict the need for transfusion within the examined patient population.Aims
Methods
Revision total hip arthroplasty in patients with Vancouver type B3 fractures with Paprosky type IIIA, IIIB, and IV femoral defects are difficult to treat. One option for Paprovsky type IIIB and IV defects involves modular cementless, tapered, revision femoral components in conjunction with distal interlocking screws. The aim of this study was to analyze the rate of reoperations and complications and union of the fracture, subsidence of the stem, mortality, and the clinical outcomes in these patients. A total of 46 femoral components in patients with Vancouver B3 fractures (23 with Paprosky type IIIA, 19 with type IIIB, and four with type IV defects) in 46 patients were revised with a transfemoral approach using a modular, tapered, cementless revision Revitan curved femoral component with distal cone-in-cone fixation and prospectively followed for a mean of 48.8 months (SD 23.9; 24 to 112). The mean age of the patients was 80.4 years (66 to 100). Additional distal interlocking was also used in 23 fractures in which distal cone-in-cone fixation in the isthmus was < 3 cm.Aims

This study compared patient-reported outcomes of three total knee arthroplasty (TKA) designs from one manufacturer: one cruciate-retaining (CR) design, and two cruciate-sacrificing designs, anterior-stabilized (AS) and posterior-stabilized (PS). Patients scheduled for primary TKA were included in a single-centre, prospective, three-armed, blinded randomized trial (n = 216; 72 per group). After intraoperative confirmation of posterior cruciate ligament (PCL) integrity, patients were randomly allocated to receive a CR, AS, or PS design from the same TKA system. Insertion of an AS or PS design required PCL resection. The primary outcome was the mean score of all five subscales of the Knee injury and Osteoarthritis Outcome Score (KOOS) at two-year follow-up. Secondary outcomes included all KOOS subscales, Oxford Knee Score, EuroQol five-dimension health questionnaire, EuroQol visual analogue scale, range of motion (ROM), and willingness to undergo the operation again. Patient satisfaction was also assessed.Aims

To analyze the short-term outcome of two types of total wrist arthroplasty (TWA) in terms of wrist function, migration, and periprosthetic bone behaviour. A total of 40 patients suffering from non-rheumatoid wrist arthritis were enrolled in a randomized controlled trial comparing the ReMotion and Motec TWAs. Patient-rated and functional outcomes, radiological changes, blood metal ion levels, migration measured by model-based radiostereometric analysis (RSA), bone mineral density (BMD) measured by dual-energy X-ray absorptiometry (DXA), complications, loosening, and revision rates at two years were compared.Aims

The optimal management of an infrapopliteal deep venous thrombosis (IDVT) following total knee arthroplasty (TKA) remains unknown. The risk of DVT propagation and symptom progression must be balanced against potential haemorrhagic complications associated with administration of anticoagulation therapy. The current study reports on a cohort of patients diagnosed with IDVT following TKA who were treated with aspirin, followed closely for development of symptoms, and scanned with ultrasound to determine resolution of IDVT. Among a cohort of 5,078 patients undergoing TKA, 532 patients (695 TKAs, 12.6%) developed an IDVT between 1 January 2014 to 31 December 2019 at a single institution, as diagnosed using Doppler ultrasound at the first postoperative visit. Of the entire cohort of 532 patients with IDVT, 91.4% (486/532) were treated with aspirin (325 mg twice daily) and followed closely. Repeat lower limb ultrasound was performed four weeks later to evaluate the status of IDVT.Aims
Methods
The purpose of this study was to examine the efficacy and safety of carbazochrome sodium sulfonate (CSS) combined with tranexamic acid (TXA) on blood loss and inflammatory responses after primary total hip arthroplasty (THA), and to investigate the influence of different administration methods of CSS on perioperative blood loss during THA. This study is a randomized controlled trial involving 200 patients undergoing primary unilateral THA. A total of 200 patients treated with intravenous TXA were randomly assigned to group A (combined intravenous and topical CSS), group B (topical CSS), group C (intravenous CSS), or group D (placebo).Aims
Methods
Complex joint fractures of the lower extremity are often accompanied by soft-tissue swelling and are associated with prolonged hospitalization and soft-tissue complications. The aim of the study was to evaluate the effect of vascular impulse technology (VIT) on soft-tissue conditioning in comparison with conventional elevation. A total of 100 patients were included in this prospective, randomized, controlled monocentre study allocated to the three subgroups of dislocated ankle fracture (n = 40), pilon fracture (n = 20), and intra-articular calcaneal fracture (n = 40). Patients were randomized to the two study groups in a 1:1 ratio. The effectiveness of VIT (intervention) compared with elevation (control) was analyzed separately for the whole study population and for the three subgroups. The primary endpoint was the time from admission until operability (in days).Aims

We report the medium-term outcomes of a consecutive series of 118 Zenith total ankle arthroplasties (TAAs) from a single, non-designer centre. Between December 2010 and May 2016, 118 consecutive Zenith prostheses were implanted in 114 patients. Demographic, clinical, and patient-reported outcome measures (PROMs) data were collected. The endpoint of the study was failure of the implant requiring revision of one or all of the components. Kaplan-Meier survival curves were generated with 95% confidence intervals (CIs) and the rate of failure calculated for each year.Aims

As the first wave of the COVID-19 pandemic began to dip, restarting elective orthopaedics became a challenge. Protocols including surgery at ‘green’ sites, self-isolation for 14 days, and COVID-19 testing were developed to minimize the risk of transmission. In this study, we look at risk effects of 14-day self-isolation on the incidence of venous thromboembolism (VTE) in our green site hospital among patients undergoing total joint replacement (TJR). This retrospective cohort study included 50 patients who underwent TJR. Basic demographic data was collected including, age, sex, American Society of Anesthesiologists (ASA) grade, body mass index (BMI), type of surgery, and complications at two and four weeks. Univariate and multivariate analysis were used to identify risk factors associated with an increased risk of VTE.Aims
Methods
To develop and validate patient-centred algorithms that estimate individual risk of death over the first year after elective joint arthroplasty surgery for osteoarthritis. A total of 763,213 hip and knee joint arthroplasty episodes recorded in the National Joint Registry for England and Wales (NJR) and 105,407 episodes from the Norwegian Arthroplasty Register were used to model individual mortality risk over the first year after surgery using flexible parametric survival regression.Aims
Methods
A lack of supporting clinical studies have been published to determine the ideal length of intramedullary nail in fixation of trochanteric fractures of the hip. Nevertheless, there has been a trend to use shorter intramedullary nails for the internal fixation of trochanteric hip fractures. Our aim was to determine if the length of nail affected the outcome. We randomized 229 patients with a trochanteric hip fracture between two implants: a ‘standard’ nail of 220 mm and a shorter nail of 175 mm, which had decreased proximal angulation (4° vs 7°) and a reduced diameter at the level of the lesser trochanter. Patients were followed up for one year by a nurse blinded to the type of implant used to determine if there were differences in mobility and pain with two nail designs. Pain was assessed on a scale of 1 (none) to 8 (severe and constant) and mobility on a scale of 1 (full mobility) to 9 (immobile).Aims

The aim of this study was to report our experience at 3.5 years with outpatient total hip arthroplasty (THA). In this prospective cohort study, we included all patients who were planned to receive primary THA through the anterior approach between 1 April 2014 and 1 October 2017. Patient-related data and surgical information were recorded. Patient reported outcome measures (PROMs) related to the hip and an anchor question were taken preoperatively, at six weeks, three months, and one year after surgery. All complications, readmissions, and reoperations were registered.Aims

The purpose of this article was to review the current literature
pertaining to the use of mobile compression devices (MCDs) for venous
thromboembolism (VTE) following total joint arthroplasty (TJA),
and to discuss the results of data from our institution. Previous studies have illustrated higher rates of post-operative
wound complications, re-operation and re-admission with the use
of more aggressive anticoagulation regimens, such as warfarin and
factor Xa inhibitors. This highlights the importance of the safety,
as well as efficacy, of the chemoprophylactic regimen.Aims
Patients and Methods
Drug therapy forms an integral part of the management
of many orthopaedic conditions. However, many medicines can produce
serious adverse reactions if prescribed inappropriately, either
alone or in combination with other drugs. Often these hazards are
not appreciated. In response to this, the European Union recently
issued legislation regarding safety measures which member states
must adopt to minimise the risk of errors of medication. In March 2014 the Medicines and Healthcare products Regulatory
Agency and NHS England released a Patient Safety Alert initiative
focussed on errors of medication. There have been similar initiatives
in the United States under the auspices of The National Coordinating
Council for Medication Error and The Joint Commission on the Accreditation
of Healthcare Organizations. These initiatives have highlighted
the importance of informing and educating clinicians. Here, we discuss common drug interactions and contra-indications
in orthopaedic practice. This is germane to safe and effective clinical
care. Cite this article:
