Antibiotic prophylaxis for joint replacement surgery is widely recommended and has been shown to reduce infection rates. Cephalosporins have commonly been used but are associated with development of Clostridium difficile associated diarrhoea (CDAD). The purpose of this study was to assess whether a change of protocol aimed at reducing CDAD, including a change of antibiotic prophylaxis would reduce rates of CDAD and other postoperative complications. We studied all 7989 patients in our trust that underwent hip or knee replacement from May 2002 to March 2009. These patients fell into two cohorts, firstly those who were prescribed cefuroxime as prophylaxis and secondly those prescribed gentamicin which was introduced following national concern regarding CDAD. Following the change of prophylaxis from cefuroxime 750mg three doses to gentamicin 4.5 mg/kg single dose the rate of CDAD reduced significantly (0.17% to 0%, p<0.03), however the rate of acute renal failure (0.29% to 0.6%, p=0.04) and pneumonia (0.71% to 1.38%, p<0.01) increased significantly. The rate of urinary tract infection (1.44% to 1.20%, p >0.05) and the overall return to theatre rate (1.86% to 2.30%, p=0.21) were not significantly changed. The spectrum of bacteria grown from infected joint replacements in the two cohorts was also analysed. The rate of deep MRSA infection was significantly less in the group given gentamicin. The frequency of other bacteria was also different between the cohorts, but not significantly so. We conclude that changing protocol including antibiotic prophylaxis in joint replacement patients can have the desired effect on a particular outcome namely CDAD but can also result in increased rates of other postoperative complications. It is also likely to result in a change in the bacterial spectrum of infected joint replacements

Aims. A systematic literature review focusing on how long before surgery concurrent viral or bacterial infections (respiratory and urinary infections) should be treated in hip fracture patients, and if there is evidence for delaying this surgery. Methods. A total of 11 databases were examined using the COre, Standard, Ideal (COSI) protocol. Bibliographic searches (no chronological or linguistic restriction) were conducted using, among other methods, the Patient, Intervention, Comparison, Outcome (PICO) template. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for flow diagram and checklist. Final reading of the complete texts was conducted in English, French, and Spanish. Classification of papers was completed within five levels of evidence (LE). Results. There were a total of 621 hits (526 COre; 95 Standard, Ideal) for screening identification, and 107 records were screened. Overall 67 full-text articles were assessed for eligibility, and 21 articles were included for the study question. A total of 46 full-text articles were excluded with reasons. No studies could be included in quantitative synthesis (meta-analyses), and there were many confounding variables including surgeons’ experience, prosthesis models used, and surgical technique. Conclusion. Patients with hip fracture and with a viral infection in the upper respiratory tract or without major clinical symptoms should be operated on as soon as possible (LE: I-III). There is no evidence that patients with coronavirus disease 2019 (COVID-19) should be treated differently. In relation to pneumonia, its prevention is a major issue. Antibiotics should be administered if surgery is delayed by > 72 hours or if bacterial infection is present in the lower respiratory tract (LE: III-V). In patients with hip fracture and urinary tract infection (UTI), delaying surgery may provoke further complications (LE: I). However, diabetic or immunocompromised patients may benefit from immediate antibiotic treatment. Cite this article: Bone Joint Res 2020;9(12):884–893

Aims. We aimed to characterise the effect of expeditious hip fracture surgery in elderly patients within 24 hours of admission on short-term post-operative outcomes. Patients and Methods. Patients age 65 or older that underwent surgery for closed femoral neck and intertrochanteric hip fractures were identified from the American College of Surgeons National Surgical Quality Improvement Program between 2011 and 2014. Multivariable propensity-adjusted logistic regressions were performed to determine associations between early surgery within 24 hours and post-operative complications, controlling for selection bias in patients undergoing early surgery based on observable characteristics. Results. A total of 26 051 patients were included in the study; 5921 (22.7%) had surgery within 24 hours of admission, while 20 130 (77.3%) patients had surgery after 24 hours. Propensity-adjusted multivariable logistic regressions demonstrated that surgery within 24 hours was independently associated with lower odds of respiratory complications including pneumonia, failure to extubate, or reintubation (odds ratio (OR) 0.78, 95% confidence interval (CI) 0.67 to 0.90), and extended length of stay (LOS) defined as ≥ 6 days (OR 0.84, 95% CI 0.78 to 0.90). Conclusion. In elderly patients with hip fractures, early surgery within 24 hours of admission is independently associated with less pulmonary complications including pneumonia, failure to extubate, and reintubation, as well as shorter LOS.

Aims

The aim of this study was to examine whether socioeconomic status (SES) is associated with a higher risk of infections following total hip arthroplasty (THA) at 30 and 90 days.

Aims. This study assessed the impact of COVID-19 on hip and distal femur fracture patient outcomes across three successive UK lockdown periods over one year. Methods. A single-centre retrospective cohort study was performed at an acute NHS Trust. Hip and distal femur fracture patients admitted within the first month from each of the three starting dates of each national lockdown were included and compared to a control group in March 2019. Data were collected as per the best practice tariff outcomes including additional outcomes as required. Data collection included COVID-19 status, time to theatre, 30-day mortality, presence of acute kidney injury (AKI) and pneumonia, and do not attempt cardiopulmonary resuscitation (DNACPR) status. Data were analyzed using an independent-samples t-test or chi-squared test with Fisher’s exact test where applicable. A p-value of < 0.05 was considered statistically significant. Results. A total of 95 patients during the pandemic were included and 20 were COVID-positive. Patients experienced a statistically significant increase in time to theatre in Lockdown 1 compared to 2019 (p = 0.039) with a decrease with successive lockdown periods by Lockdown 3. The 30-day mortality increased from 8.8% in 2019 to 10.0% to 14.8% in all lockdown periods. COVID-positive patient mortality was 30.0% (p = 0.063, odds ratio (OR) = 4.43 vs 2019). The rates of AKI and pneumonia experienced were higher for patients during the pandemic. The highest rates were experienced in COVID-positive patients, with 45.0% of patients with AKI versus 27.0% in 2019 (p = 0.38, OR = 1.80), and 50.0% of patients diagnosed with pneumonia versus 16.2% in 2019 (p = 0.0012, OR = 5.17). The percentage of patients with a DNACPR increased from 30.0% in 2019 to 60.7% by Lockdown 3 (p = 0.034, OR = 3.61). Conclusion. COVID-positive hip and distal femur fracture patients are at a higher risk of mortality due to AKI and pneumonia. Patient outcomes have improved with successive lockdowns to pre-pandemic levels.

Aims. The aim of this study was to identify modifiable risk factors associated with mortality in patients requiring revision total hip arthroplasty (THA) for periprosthetic hip fracture. Methods. The electronic records of consecutive patients undergoing revision THA for periprosthetic hip fracture between December 2011 and October 2018 were reviewed. The data which were collected included age, sex, body mass index (BMI), American Society of Anesthesiologists (ASA) classification, the preoperative serum level of haemoglobin, time to surgery, operating time, blood transfusion, length of hospital stay, and postoperative surgical and medical complications. Univariate and multivariate logistic regression analyses were used to determine independent modifiable factors associated with mortality at 90 days and one year postoperatively. Results. A total of 203 patients were identified. Their mean age was 78 years (44 to 100), and 108 (53%) were female. The median time to surgery was three days (interquartile range (IQR) 2 to 5). The mortality rate at one year was 13.8% (n = 28). The commonest surgical complication was dislocation (n = 22, 10.8%) and the commonest medical complication within 90 days of surgery was hospital-acquired pneumonia (n = 25, 12%). Multivariate analysis showed that the rate of mortality one year postoperatively was five-fold higher in patients who sustained a dislocation (odds ratio (OR) 5.03 (95% confidence interval (CI) 1.60 to 15.83); p = 0.006). The rate of mortality was also four-fold higher in patients who developed hospital-acquired pneumonia within 90 days postoperatively (OR 4.43 (95% CI 1.55 to 12.67); p = 0.005). There was no evidence that the time to surgery was a risk factor for death at one year. Conclusion. Dislocation and hospital-acquired pneumonia following revision THA for a periprosthetic fracture are potentially modifiable risk factors for mortality. This study suggests that surgeons should consider increasing constraint to reduce the risk of dislocation, and the early involvement of a multidisciplinary team to reduce the risk of hospital-acquired pneumonia. We found no evidence that the time to surgery affected mortality, which may allow time for medical optimization, surgical planning, and resource allocation.

This study aimed to assess the outcomes of patients with complex rib fractures undergoing operative or non-operative management at our center over a six-year time period. Retrospective analysis was performed to identify all patients with complex rib fractures at our center from May 2016 to September 2022. Outcome measures included mechanical ventilation, tracheostomy, pneumonia, and mortality at one year. 388 patients with complex rib fractures were identified. 37 (10%) patients fulfilled criteria for surgical management and underwent rib fracture fixation; 351 patients were managed non-operatively with anaesthetic block or analgesia alone. The fixation group had a significantly higher proportion of patients with flail chest (30 (81%) vs 94 (27%), p<0.001) and were significantly more likely to require ICU admission (30 (81%) vs. 16 (5%), p<0.001) than the non-operative group. At one year follow-up, no significant differences were seen for mortality between these groups (1 (3%) vs. 27 (7%), p=0.276). Of the surgical management group, those that underwent fixation <72 hours post injury were significantly less likely to develop pneumonia than those who were delayed >72 hours (2 (18%) vs 15 (58%), p=0.038), with downward trends noted for ICU length of stay (6 vs 10 days, p=0.140) and duration of mechanical ventilation (5 vs 8 days, p=0.177); no significant differences were seen for tracheostomy (3 vs. 5, p=0.588) or mortality (0 vs 1, p=0.856). Surgical fixation of complex rib fractures improves outcomes in selected patient groups. Early surgical fixation led to reduced rates of pneumonia and may improve other outcome measures

Aims. This study aimed to investigate the risk of postoperative complications in COVID-19-positive patients undergoing common orthopaedic procedures. Methods. Using the National Surgical Quality Improvement Programme (NSQIP) database, patients who underwent common orthopaedic surgery procedures from 1 January to 31 December 2021 were extracted. Patient preoperative COVID-19 status, demographics, comorbidities, type of surgery, and postoperative complications were analyzed. Propensity score matching was conducted between COVID-19-positive and -negative patients. Multivariable regression was then performed to identify both patient and provider risk factors independently associated with the occurrence of 30-day postoperative adverse events. Results. Of 194,121 included patients, 740 (0.38%) were identified to be COVID-19-positive. Comparison of comorbidities demonstrated that COVID-19-positive patients had higher rates of diabetes, heart failure, and pulmonary disease. After propensity matching and controlling for all preoperative variables, multivariable analysis found that COVID-19-positive patients were at increased risk of several postoperative complications, including: any adverse event, major adverse event, minor adverse event, death, venous thromboembolism, and pneumonia. COVID-19-positive patients undergoing hip/knee arthroplasty and trauma surgery were at increased risk of 30-day adverse events. Conclusion. COVID-19-positive patients undergoing orthopaedic surgery had increased odds of many 30-day postoperative complications, with hip/knee arthroplasty and trauma surgery being the most high-risk procedures. These data reinforce prior literature demonstrating increased risk of venous thromboembolic events in the acute postoperative period. Clinicians caring for patients undergoing orthopaedic procedures should be mindful of these increased risks, and attempt to improve patient care during the ongoing global pandemic.

Aims. Within the UK, around 70,000 patients suffer neck of femur (NOF) fractures annually. Patients presenting with this injury are often frail, leading to increased morbidity and a 30-day mortality rate of 6.1%. COVID-19 infection has a broad spectrum of clinical presentations with the elderly, and those with pre-existing comorbidities are at a higher risk of severe respiratory compromise and death. Further increased risk has been observed in the postoperative period. The aim of this study was to assess the impact of COVID-19 infection on the complication and mortality rates of NOF fracture patients. Methods. All NOF fracture patients presenting between March 2020 and May 2020 were included. Patients were divided into two subgroup: those with or without clinical and/or laboratory diagnosis of COVID-19. Data were collected on patient demographics, pattern of injury, complications, length of stay, and mortality. Results. Overall, 132 patients were included. Of these, 34.8% (n = 46) were diagnosed with COVID-19. Bacterial pneumonia was observed at a significantly higher rate in those patients with COVID-19 (56.5% vs 15.1%; p =< 0.000). Non respiratory complications such as acute kidney injury (30.4% vs 9.3%; p =0.002) and urinary tract infection (10.9% vs 3.5%; p =0.126) were also more common in those patients with COVID-19. Length of stay was increased by a median of 21.5 days in patients diagnosed with COVID-19 (p < 0.000). 30-day mortality was significantly higher in patients with COVID-19 (37.0%) when compared to those without (10.5%; p <0.000). Conclusion. This study has shown that patients with a neck of femur fracture have a high rate of mortality and complications such as bacterial pneumonia and acute kidney injury when diagnosed with COVID-19 within the perioperative period. We have demonstrated the high risk of in hospital transmission of COVID-19 and the association between the infection and an increased length of stay for the patients affected.

Unstable chest wall injuries have high rates of mortality and morbidity. These injuries can lead to respiratory dysfunction, and are associated with high rates of pneumonia, sepsis, prolonged ICU stays, and increased health care costs. Numerous studies have demonstrated improved outcomes with surgical fixation compared to non-operative treatment. However, an adequately powered multi-centre randomized controlled study using modern fixation techniques has been lacking. We present a multi-centred, prospective, randomized controlled trial comparing surgical fixation of acute, unstable chest wall injuries with the current standard of non-operative management. Patients aged 16–85 with a flail chest (3 or more consecutive, segmental, displaced rib fractures), or severe deformity of the chest wall, were recruited from multiple trauma centers across North America. Exclusion criteria included: severe pulmonary contusion, severe head trauma, randomization>72 hours from injury, inability to perform surgical fixation within 96 hours from injury (in those randomized to surgery), fractures of the floating ribs, or fractures adjacent to the spine not amendable to surgical fixation. Patients were seen in follow-up for one year. The primary outcome was days free from mechanical ventilation in the first 28 days following injury. Secondary outcomes were days in ICU, rates of pneumonia, sepsis, need for tracheostomy, mortality, general health outcomes, pulmonary function testing, and other complications of treatment. A sample size of 206 was required to detect a difference of 2 ventilator-free days between the two groups, using a 2-tailed alpha error of 0.05 and a power of 0.80. A total of 207 patients were recruited from 15 sites across Canada and USA, from 2011–2018. Ninety-nine patients were randomized to non-operative treatment, and 108 were randomized to surgical fixation. Overall, the mean age was 53 years, and 75% of patients were male, with 25% females. The commonest mechanisms of injury were: motor vehicle collisions (34%), falls (20%), motorcycle collisions (14%), and pedestrian injuries (11%). The mean injury severity score (ISS) at admission was 26, and patients had a mean of 10 rib fractures. Eighty-nine percent of patients had pneumothorax, 76% had haemothorax, and 54% had pulmonary contusion. There were no differences between the two groups in terms of demographics. The final results will be available and presented at the COA meeting in Halifax. This is the largest randomized controlled trial to date, comparing surgical fixation to non-operative treatment of unstable chest wall and flail chest injuries. The results of this study will shed light on the best treatment options for patients with such injuries, help understand outcomes, and guide treatment. The final results will be available and presented at the COA meeting in Halifax

Abstract. Background. Elderly patients with degenerative lumbar disease are increasingly undergoing posterior lumbar decompression without instrumented stabilisation. There is a paucity of studies examining clinical outcomes, morbidity & mortality associated with this procedure in this population. Methods. A retrospective analysis of aged 80–100 years who underwent posterior lumbar decompression without instrumented stabilisation at University Hospitals of Derby &Burton between 2016–2020. Results. Total 167 eligible patients, 163 octogenarians & 4 nonagenarians. Mean age was 82.78 ± 3.07 years. Mean length of hospital stay 4.79 ± 10.92 days. 76% were pain free at 3months following decompression. The average Charleston co-morbidity index (CCI) was 4.87. No association found with CCI in predicting mortality (ODD ratio 0.916, CI95%). 17patients suffered complications; dural tear (0.017%), post-op paralysis (0.017%), SSI(0.01%), and 0.001% of hospital acquired pneumonia, delirium, TIA, urinary retention, ileus, anaemia. High BMI (35+) was associated with increased incidence of complication (CI 95%, p<0.002). There was significant social drift following discharge as 147 patients went home and 4 patients to rehabilitation facility (p<0.001FE test). The mean operative time was 91.408±41.17 mins and mean anaesthetic time was 36.8±16.06 mins. Prolonged operative time was not associated with increased mortality.2year revision decompression rate was 0.011%. Conclusion. Posterior lumbar decompression without instrumented stablisation in elderly is safe & associated with low mortality with 99.5%survival at 1 year. It significantly improves PROMs & has extremely low revision rate. Incidence of post-op complication is <0.05% and 54% of patients get discharged within 72hours of surgery. Careful selection & optimising patients with high BMI would reduced perioperative morbidity and mortality

SARS-CoV-2 emerged in Wuhan, China in December 2019 causing pneumonia and resulting in a pandemic, commonly known as COVID-19. This pandemic led to significant changes to our daily lives due to restrictions, such as social distancing, quarantining, stay at home orders and closure of restaurants and shops among other things. The psychological effects of this uncertainty as well as of these changes to our lives have been shown to be significant. This study is a prospective study investigating the mental effects of the pandemic on hand and wrist patients seen in our clinic during this pandemic. A prospective database on wrist pain was used to identify patients seen in our hand clinic from January 1, 2018 to December 10, 2021. All participants had been diagnosed with either radial sided wrist pain or ulnar side wrist pain. The Center for Epidemiological Studies Depression (CES-D) Scale was used to assess the mental health of our participants before and during this pandemic. An independent samples t-test was used to compare the scores of the 2 groups. A total of 437 CES-D questionnaires were collected during this period. 118 of them belonging to the pandemic group and 319 to the pre-pandemic group. A difference (p < 0 .05) in the CES-D score was observed between the pre-pandemic and during pandemic groups. The mean score for the pre-pandemic group was found to be 9.23 (8.94) and 12.81 (11.45) for the pandemic group. However, despite the increase in score, it didn't exceed the cut off score of 16 or greater used to assess depression. Our results indicate that there was a slight increase in score for depression in hand and wrist patients, but not above the cut off level of 16 to be of a significant risk for depression. Other global studies have shown an increase in depression in the general public. Our mild results might be attributed to the fact that British Columbia did not implement severe restrictions compared to other countries or regions, i.e no stay at home orders. Additionally, our study population was skewed and included more middle age and older patients compared to younger ones and age might be a factor in keeping the score down

We aimed to use data from a randomized controlled trial (RCT) comparing the sliding hip screw vs. intramedullary nailing (IMN) for trochanteric fractures to examine complication rates between those managed with a short vs. long IMN. This is a secondary analysis using one arm of an RCT of patients ≥18 years with trochanteric fractures. We examined differences in fracture-related (femoral shaft fracture, implant failure, surgical site infection (SSI), nonunion, limb shortening, and pain) and medical (organ failure, respiratory distress, stroke, deep vein thrombosis [DVT] gastrointestinal upset, pneumonia, myocardial infarction, sepsis, or urinary tract infection) adverse events (AE), and readmission between short vs. long IMNs. We included 412 trochanteric fracture patients, 339 (82.2%) of whom received a short (170mm–200mm) nail, while 73 (17.7%) received a long (260mm–460 mm) nail. Patients in the long group were more likely to be admitted from home (vs. an institution), and have comorbidities, or more complex fracture types. Patients in the long group had higher rates of fracture-related AE (12.3%) vs. the short group (3.5%). Specifically, SSI (5.5% vs. 0.3%) and pain (2.7% vs. 0.0%) were significantly higher in the long group. Patients in the long group were also more likely to develop DVT (2.7% vs. 0.3%), and be readmitted to the hospital (28.8% vs. 20.7%). Following covariable adjustment, long nails remained associated with a higher odds of fracture-related AE (5.11, 1.96–13.33) compared to short nails. We found no association between the adjusted odds of readmission and nail length (1.00, 0.52–1.94). Our analyses revealed that trochanteric fracture patients managed with long IMN nails may have a higher odds of fracture-related AE compared to short nails. Future research is required to validate these findings with larger event rates, and further optimize IMN for trochanteric fracture patients

Aims. The impact of tobacco use on readmission and medical and surgical complications has been documented in hip and knee arthroplasty. However, there remains little information about the effect of smoking on the outcome after total shoulder arthroplasty (TSA). We hypothesized that active smokers are at an increased risk of poor medical and surgial outcomes after TSA. Methods. Data for patients who underwent arthroplasty of the shoulder in the USA between January 2011 and December 2015 were obtained from the National Readmission Database, and 90-day readmissions and complications were documented using validated coding methods. Multivariate regression analysis was performed to quantify the risk of smoking on the outcome after TSA, while controlling for patient demographics, comorbidities, and hospital-level confounding factors. Results. A total of 196,325 non-smokers (93.1%) and 14,461 smokers (6.9%) underwent TSA during the five-year study period. Smokers had significantly increased rates of 30- and 90-day readmission (p = 0.025 and 0.001, respectively), revision within 90 days (p < 0.001), infection (p < 0.001), wound complications (p < 0.001), and instability of the prosthesis (p < 0.001). They were also at significantly greater risk of suffering from pneumonia (p < 0.001), sepsis (p = 0.001), and myocardial infarction (p < 0.001), postoperatively. Conclusion. Smokers have an increased risk of readmission and medical and surgical complications after TSA. These risks are similar to those found for smokers after hip and knee arthroplasty. Many surgeons choose to avoid these elective procedures in patients who smoke. The increased risks should be considered when counselling patients who smoke before undertaking TSA.

Aim. Sepsis is a life-threatening complication of periprosthetic joint infections (PJI) that requires early and effective therapy. This study aims to investigate the epidemiology, associated risk factors, and outcome of sepsis in the context of periprosthetic joint infections (PJI). Method. This single-center retrospective cohort study included patients treated for PJI from 2017 to 2020. Patients were classified based on the criteria of the European Bone and Joint Infection Society. The presence of sepsis was determined using the SOFA score and SIRS criteria. The cohort with PJI and sepsis (sepsis) was compared to patients with PJI without sepsis (non-sepsis). Risk factors considered were patient characteristics, affected joints, surgical therapy, microbiological findings, preexisting medical conditions, clinical symptoms, and symptom duration. Outcome parameters were mortality, length of hospital stay, and length of stay in the intensive care unit. Results. A total of 109 patients with PJI were identified, of whom 45 patients (41.3%) met the criteria for sepsis. Patients with sepsis had more severe preexisting diseases compared with the non-sepsis cohort (Charlson Comorbidity Index 3.8 vs. 2.8; p≤0.001). An increased odds ratio (OR) for a septic course was found for the comorbidities pneumonia (8.2; p=0.001), myocardial infarction (2.0; p=0.02), atrial fibrillation (3.3; p=0.01), diabetes mellitus (1.2; p=0.04), endocarditis (5.5; p=0.01), and renal disease (2.0; p≤0.001). Infection with Staphylococcus aureus (sepsis 20 vs. non-sepsis 10; p=0.002), Streptococcus dysgalactiae (sepsis 7 vs. non-sepsis 2; p=0.002) and Candida albicans (sepsis 5 vs. non-sepsis 0; p=0.01) were more prevalent in patients with sepsis. In the sepsis cohort, further infectious foci were present in addition to PJI in 57.8% of patients, compared to 18.8% in the non-sepsis cohort. The presence of sepsis was associated with a longer hospital stay (sepsis 68 days vs. non-sepsis 38 days; p=0.001) and longer intensive care unit stay (sepsis 12 days vs. non-sepsis 2 days; p=0.001). In-hospital mortality was ten times higher in the sepsis cohort compared to non-septic patients (sepsis 11/42 vs. non-sepsis 2/64; OR 10.3; p=0.01). Conclusions. In a relevant proportion of patients, PJI can lead to a septic course of disease associated with increased mortality. Particularly in patients with preexisting diseases, increased attention is required, and comprehensive screening for other foci of infection seems mandatory. In addition to highly virulent pathogens such as staphylococci and streptococci, fungal infections should be considered as causative pathogens in septic patients with PJI

Abstract. Objective. To investigate the safety and cost-effectiveness of interscalene brachial plexus block/regional anaesthesia (ISB-RA) in patients undergoing reverse total shoulder replacement. Methods. This retrospective study included 15 patients with symptomatic rotator cuff arthropathy who underwent reverse total shoulder arthroplasty (rTSA) under ISB-RA without general anaesthesia in the beach chair position from 2010 to 2018. The mean patient age was 77 years (range 59–82 years). Patients had associated medical comorbidities: American Society of Anesthesiologists (ASA) grade 2–4. Assessed parameters were: duration of anaesthesia, intra-operative systolic blood pressure variation, sedation and vasopressor use, duration of post-operative recovery, recovery scores, length of stay, and complications. A robust cost analysis was also performed. Results. The mean (range) duration of anaesthesia was 38.66 (20–60) min. Maximum and minimum intra-operative systolic blood pressure ranges were 130–210 and 75–145 mmHg, respectively (mean [range] drop, 74.13 [33–125] mmHg). Mean (range) propofol dose was 1.74 (1–3.0) mg/kg/h. The Median (interquartile range) post-operative recovery time was 30 (20–50) min. The mean (range) postoperative recovery score (local scale, range 5–28 where lower values are superior) was 5.2 (5–8). The mean (range) length of stay was 8 (1–20 days); the two included patients with ASA grade 2 were both discharged within 24 hours. One patient with predisposing history developed pneumonia; however, there were no complications related to ISB-RA. The mean (range) cost per patient was £101.36 (£59.80-£132.20). Conclusions. Our data demonstrate that rTSA under ISB-RA is safe, cost-effective and a potentially viable alternative for patients with multiple comorbidities. Notably, patients with ASA grade 2 who underwent rTSA under ISB-RA had a reduced length of stay and were discharged within 24 hours

Aims. The aim of this study was to compare the rate of perioperative complications following aseptic revision total hip arthroplasty (THA) in patients aged ≥ 80 years with that in those aged < 80 years, and to identify risk factors for the incidence of serious adverse events in those aged ≥ 80 years using a large validated national database. Patients and Methods. Patients who underwent aseptic revision THA were identified in the 2005 to 2015 National Surgical Quality Improvement Program (NSQIP) database and stratified into two age groups: those aged < 80 years and those aged ≥ 80 years. Preoperative and procedural characteristics were compared. Multivariate regression analysis was used to compare the risk of postoperative complications and readmission. Risk factors for the development of a serious adverse event in those aged ≥ 80 years were characterized. Results. The study included 7569 patients aged < 80 years and 1419 were aged ≥ 80 years. Multivariate analysis showed a higher risk of perioperative mortality, pneumonia, urinary tract infection and the requirement for a blood transfusion and an extended length of stay in those aged ≥ 80 years compared with those aged < 80 years. Independent risk factors for the development of a serious adverse event in those aged ≥ 80 years include an American Society of Anesthesiologists score of ≥ 3 and procedures performed under general anaesthesia. Conclusion. Even after controlling for patient and procedural characteristics, aseptic revision THA is associated with greater risks in patients aged ≥ 80 years compared with younger patients. This is important for counselling and highlights the need for medical optimization in these vulnerable patients. Cite this article: Bone Joint J 2018;100-B:143–51

Introduction. This study was designed to evaluate the effect of discharge timing on 30-day major and minor complications in patients undergoing total knee arthroplasty (TKA) while adjusting for other variables. Methods. Patients 18 years and older undergoing TKA between the years of 2005 and 2016 were identified from the American College of Surgeons National Surgical Quality Improvement Program (NSQIP). Patients whose length of stay (LOS) was >4 days were excluded. Patient demographics, anesthesia type, length of operation and hospital stay, as well as 30-day major and minor complications were collected from the database. Chi square tests were utilized to compare the unadjusted rates of complications between patients whose LOS was 0, 1, 2, and 3–4 days. Multivariable regression was utilized to evaluate the effect of LOS on complication rates, while adjusting for age, American Society of Anesthesiologist (ASA) class, type of anaesthesia, functional status, comorbidities, sex, steroid/immunosuppressant use, body mass index (BMI), diabetes, length of operation and smoking status. Results. A total of 198,191 TKA patients were identified (average age 66 ± 10 years). Average LOS was 2.5 ± 0.81 days. Of these patients, 1,667 (0.84%) were discharged the day of surgery, while 16,186 (8.17%) were discharged one-day post-surgery, 63,540 (32.06%) were discharged on day two, and 115,471 (58.25%) were discharged between 3 and 4 days post-surgery. Unadjusted rates of complications were significantly higher for patients who were discharged on the day of surgery (2.64%), or those whose LOS was 3–4 days (2.78%) compared to those whose LOS was 1 (1.40%) or 2 days (1.67%). After adjusting for all relevant covariables, discharge on the day of surgery increased the risk of major complications by 1.8 (95% Confidence interval [95%CI] 1.2–2.8), and minor complications by 1.6 (95%CI 1.2 – 2.2) compared to patients whose LOS was 2 days. A LOS of 1 day did not affect the risk of major complications compared to a LOS of 2 days, while a LOS of 3–4 days increased the risk of major complications by 1.4 (95%CI 1.3 – 1.6), and minor complications by 1.6 (95%CI 1.4 – 1.7). Regarding specific complications, same-day discharge remained an independent predictor of myocardial infarction (MI), cardiac arrest, pulmonary embolism (PE), unplanned reintubation, >48 hours on ventilator, pneumonia and renal insufficiency, while a LOS of 3–4 days remained an independent predictor of MI, cardiac arrest, sepsis, acute renal failure, PE, unplanned reintubation, >48 hours on ventilator, stroke, deep vein thrombosis, pneumonia, urinary tract infection, renal insufficiency, deep and superficial surgical site infection, and wound disruption compared to patients whose LOS was 2 days (p<0.01). Conclusion. Discharge on days 1–2 postoperatively following TKA appears to have superior outcomes compared to discharge on the day of surgery, or on days 3–4. Prospective clinical data is required to confirm the effect of discharge timing on postoperative outcomes following TKA

INTRODUCTION. Shoulder arthroplasty (SA) is an effective procedure for managing patients with shoulder pain secondary to degenerative joint disease or end stage arthritis that has failed conservative treatment. Insurance status has been shown to be an indicator of patient morbidity and mortality. The objective of the current study is to evaluate the effect of patient insurance status on outcomes following shoulder replacement surgery. METHODS. Data was obtained from the Nationwide Inpatient Sample between 2004 and 2011. Analysis included patients undergoing shoulder arthroplasty procedures determined by ICD-9 procedure codes. Patient demographics and comorbidities were analyzed and stratified by insurance type. The primary outcome was medical and surgical complications occurring during the same hospitalization with secondary analysis of mortality. Pearson's chi¬squared test and multivariate regression were performed. RESULTS. A data inquiry identified 103,290 patients (68,578 Medicare, 27,159 private insurance, 3,544 Medicaid/uninsured, 4,009 Other) undergoing partial, total and reverse total shoulder replacements. The total number of complications was 17,810 (17.24%), and the top three complications included acute cardiac events (8,165), urinary tract infections (3,154), and pneumonia (1,635). The highest complication rate was observed in the Medicare population (20.3%), followed by the Medicaid/uninsured (16.9%), other (11.1%), and the privately-insured cohort (10.5%). Multivariate regression analysis indicated that having Medicare insurance, white race, increasing age, higher comorbidity, and urgent or emergent admissions was associated with medical complications. Black patients, increasing age and comorbities was associated with surgical complications. Overall mortality was 0.20% and was more common in total shoulder arthroplasty and surgeries done on emergent or urgent admissions. DISCUSSION. This data reveals that patients with Medicare, Medicaid or no insurance were more likely to have medical complications, most commonly cardiac complications, UTIs and pneumonia. Primary insurance payer status can be considered as an independent risk factor during preoperative risk stratification and planning

Aims. Flail chest from a blunt injury to the thorax is associated with significant morbidity and mortality. Its management globally is predominantly non-operative; however, there are an increasing number of centres which undertake surgical stabilisation. The aim of this meta-analysis was to compare the efficacy of this approach with that of non-operative management. Patients and Methods. A systematic search of the literature was carried out to identify randomised controlled trials (RCTs) which compared the clinical outcome of patients with a traumatic flail chest treated by surgical stabilisation of any kind with that of non-operative management. Results. Of 1273 papers identified, three RCTs reported the results of 123 patients with a flail chest. Surgical stabilisation was associated with a two thirds reduction in the incidence of pneumonia when compared with non-operative management (risk ratio 0.36, 95% confidence interval (CI) 0.15 to 0.85, p = 0.02). The duration of mechanical ventilation (mean difference -6.30 days, 95% CI -12.16 to -0.43, p = 0.04) and length of stay in an intensive care unit (mean difference -6.46 days, 95% CI 9.73 to -3.19, p = 0.0001) were significantly shorter in the operative group, as was the overall length of stay in hospital (mean difference -11.39, 95% CI -12.39 to -10.38, p < 0.0001). Conclusion. Surgical stabilisation for a traumatic flail chest is associated with significant clinical benefits in this meta-analysis of three relatively small RCTs.

Flail chest and multiple rib fractures are common injuries in trauma patients. Several small randomized studies have suggested significant improvements in patient outcomes with surgical fixation, compared to nonoperative management, yet emerging population-level data report some conflicting results. The objectives of this study were to compare the results of surgical fixation and nonoperative management of multiple rib fractures and flail chest injuries and to assess whether effects varied by study design limitations, including risk of confounding by indication. A comprehensive search of electronic databases (Medline, Embase, Web of Science) was performed to identify randomized controlled trials and observational studies. Random effects models were used to evaluate weighted risk ratios (RR) and mean differences (MD). Risk of confounding by indication was assessed for each study (low, medium, and high risk), and this categorization was used to stratify results for clinical outcomes. Publication bias was assessed. Thirty-nine studies, with a total of 19,357 patients met inclusion criteria. Compared to nonoperative treatment, surgical fixation of flail chest and multiple rib fractures was associated with decreased risk of death (overall RR 0.40, 95% confidence interval (CI) 0.28–0.56), pneumonia (overall RR 0.70, 95% CI 0.52–0.93), tracheostomy (overall RR 0.62, 95% CI 0.41–0.93), and chest wall deformity (overall RR 0.16, 95% CI 0.06–0.42). However, many of the observational studies were at risk of confounding by indication, and results varied according to risk of confounding by indication. Differences in ventilator time, intensive care unit length of stay (LOS), hospital LOS, and return to work will be assessed (results pending). Compared to nonoperative treatment, surgical fixation of flail chest and multiple rib fractures is associated with improved clinical outcomes. Discrepancies between some study results may be due to confounding by indication. Additional prospective randomized trials and high-quality observational studies are required to overcome potential threats to validity and to expand on existing evidence around optimal treatment of these injuries

Background: Since high incidences of serious complications like death and pneumonia during halo vest immobilization (HVI) have been reported in recent literature, a tendency of restraint in using the halo vest is rising. Nevertheless, most of these studies were small-scale retrospective reports. The real incidence of complications in a highvolume center with sufficient experience is unknown. It was our objective to determine incidence and risk factors associated with complications during HVI prospectively. Methods: During a 5-year period a prospective cohort study was performed in a single level-I trauma and spinal disorders center. Data of all traumatic and non-traumatic patients who underwent HVI were prospectively collected. Every complication during follow-up, i.e. the period of HVI, was recorded. Primary outcome was presence or absence of complications. Statistical significance of relations between 30 covariates and primary outcome was determined with Chi-square analysis. Results: In 239 patients treated with HVI 26 major, 59 intermediate and 132 minor complications were observed. Fourteen patients (6%) died during the treatment, although only three were possibly related directly to the immobilization. Increasing age (p=0.005) was the only risk factor significantly related to mortality during HVI. Patients over the age of 70 were especially at risk (p=0.002). Twelve patients (5%) acquired pneumonia during HVI. Halo related complications ranged from 3 patients (1%) with incorrect initial assembly of the halo vest to 29 patients (12%) with pin site infections. Both pin site infection (p=0.003) and pin loosening (p=0.021) have been identified as significant risk factors in development of pin site penetration. Conclusions: Compared to previous retrospective reports, we found a lower percentage of mortality and pneumonia during HVI. Nevertheless, the numbers of minor complications remain substantial. This study confirms that awareness and responsiveness to minor complications can prevent subsequent development of serious morbidities and reduce mortality, while it is the first prospective report to identify risk factors for the development of complications during HVI

Surgical fixation of tibial plateau fractures in elderly patients with open reduction and internal fixation (ORIF) provides inferior outcomes compared to younger patients. Primary total knee arthroplasty (TKA) may be of benefit in patients with pre-existing arthritis, marked osteopenia, or severe fracture comminution. Rationale for primary TKA includes allowing early mobility in hopes of reducing associated complications such as deconditioning, postoperative pneumonia, or venous thromboembolism, and reducing post-traumatic arthritis which occurs in 25% to 45% of patients and requires revision TKA in up to 15%. Subsequent revision TKA has been shown to have significantly worse outcomes than TKA for primary osteoarthritis. This systematic review sought to elicit the clinical outcomes and peri-operative complication rates following primary TKA for tibial plateau fractures. A comprehensive search of MEDLINE, Embase, and PubMed databases from inception through March 2018 was performed in accordance with PRISMA guidelines. Two reviewers independently screened papers for inclusion and identified studies featuring perioperative complications and clinical outcomes following primary TKA for tibial plateau fractures. Studies were included for final data analysis if they met the following criteria: (1) studies investigating TKA as the initial treatment for tibial plateau fractures, (2) patients must be ≥ 18 years old, (3) have a minimum ≥ 24-month follow-up, and (4) must be published in the English language. Case series, cohort, case-control, and randomized-control trials were included. Weighted means and standard deviations are presented for each outcome. Seven articles (105 patients) were eligible for inclusion. The mean age was 73 years and average follow-up was 39 months. All-cause mortality was 4.75% ± 4.85. The total complication rate was 15.2% ± 17.3% and a total of eight patients required revision surgery. Regarding functional outcomes, the Knee Society score was most commonly reported. The average score on the knee subsection was 85.6 ± 5.5 while the average function subscore was 64.6 ± 13.7. Average range of motion at final follow-up was 107.5° ± 10°. Total knee arthroplasty for the treatment of acute tibial plateau fractures is enticing to allow early mobility and weightbearing. However, complication rates remain high. Functional outcomes are similar to patients treated with ORIF or delayed arthroplasty. Given these findings, surgeons should be highly selective in performing TKA for the immediate treatment of tibial plateau fractures

Introduction: Risk-profiling of patients in knee arthroplasty to prepare for postoperative complications is becoming more important. Materials and Methods: Major complications (hematoma, cardio-vascular complication, deep venous thrombosis, pulmonary embolism, joint infection and pneumonia) following 17644 knee arthroplasties occurring within the postoperative hospitalization period have been documented based on a standardized protocol used for external quality assessment in Germany. Using logistic regression, the influence of potential risk factors were assessed for their significance on postoperative complications and uni-variate analysis used to assess this influence on every single major complication. The influence of patient age and the surgery time on major complications were calculated using ANOVA. Results: Major postoperative complications occurred in 7.22 per cent with hematoma in 2.89, cardio-vascular complications in 1.79, deep venous thrombosis in 1.23, pulmonary embolism in 0.23, joint infection in 0.82 and pneumonia in 0.25 per cent. Patient age, surgery time, gender, high classification according to the American Association of Anesthesiologists, allogeneic blood transfusion and lateral release significantly increased the rate of postoperative complications. Males are more prone to suffer from hematoma, joint infection and pneumonia in the immediate postoperative course. Females are more endangered for deep venous thrombosis. Extended surgery time increased the rate of hematoma and infection, increased patient age elevated the rate of hematoma, cardiovascular complication and pneumonia. Alloge-neic blood transfusion increased the risk of all major complications except deep venous thrombosis. Conclusions Male gender, allogeneic blood transfusion, increased age and surgery time elevate immediate postoperative complications following knee arthroplasty

Aim. Bone and joint infections are frequent in African countries and their prevention and treatment remain a great challenge. This study aimed to determine the bacterial ecology and sensitivity of isolates to locally available antibiotics in orthopedic unit of a tertiary care hospital in Cameroun. Method. During a 12 months period, all the patients presenting with osteomyelitis or septic arthritis irrespective of the mechanism and the location were enrolled in this study. Intraoperative samples (biopsies) were taken and sent for microbiological analysis, and all strains isolated were tested for antibiotic sensitivity according to conventional methods. Results. on the 52 bacteriological analysis performed, 48 were positive. The most isolated germs were staphylococcus aureus (41.9 % of isolates), pseudomonas aeruginosa (14.5 %), Escherichia coli (14.5 %) and Klebsiella pneumonia (12.9 %). The antibiotic sensitivity pattern revealed worrying resistance rates for common and affordable antibiotics: ampicillin (94 %), amoxicillin + clavulanic acid (63.9 %), ceftazidim (65.5%), ticarcillin + clavulanate (57.4%), gentamycin (49 %), ciprofloxacin (40 %), cefuroxim (40 %), tobramycin (38.5 %). The strains of Staphylococcus aureus showed resistance to penicillin G (83%), oxacillin (25%), lincomycin (27%) and vancomycin (7%). The overall highest sensitivity rates were observed with amikacin (92 %) and imipenem (90.1%), which for many patients were the only effective locally available antibiotics. The daily cost of treatment with those two antibiotics is close to the guaranteed minimum wage in our country. Conclusions. The alarming rate of multidrug-resistant bacteria makes the long antibiotic treatment of bone infections unaffordable (in a context of lack of social insurance) for most of our patients. We advocate strong national policies for bacteriological surveillance and antibiotic misuse de-escalation to prevent antibiotic resistance

Introduction The frequency of spine surgery in the elderly continues to increase in parallel with the overall aging of the population. The main goal of this study was to determine if age is a risk factor for major complications in spine surgery. In addition, other co-morbidities and the relationship with age and potential for major complications were explored. Methods All adult patients undergoing spine surgery at our center over a four-year period were included in this study, for a total of 1937 patients (605 age 18 – 39; 1001 age 40–64, 331 age 65 and over). One independent observer abstracted baseline medical histories and co-morbidities as well as post-operative complications. Major risk factors explored included history of cardiac, cancer, smoking, diabetes, substance abuse, obesity, respiratory problems, previous infections and hypercholesterolemia. Details of surgical procedure, including type of surgery, duration of surgery and blood loss were also captured. Major complications were defined as death, CVA, embolism, pneumonia and deep wound infections. Patients ranged in age from 18 years to 91 (average age 48 years) and 41% were males. Thirty percent of the population was deformity patients, 49% degenerative patients and the remaining 21% had various other spine problems. Thirty-five percent of the patients underwent a combined anterior posterior procedure, 13% anterior alone and 34% posterior alone. Statistical analysis included descriptive summary, vicariate correlation to assess individual risk factors (university analysis) and multivariate regression. Results The overall major complication rate was 2.1% (40 patients). There were no intra- or post-operative deaths. Major complications included 7 CVA (0.4%), 2 embolisms (0.1%), 3 deep wound infections (0.2%) and 28 pneumonia (1.4). For patients age 65 or older,. Overall, 61% of the patients had at least one of the major risk factors. The number of major risk factors increased with increased age. The percent of patients with any given risk factor also increased with age. When no other factors were taken into account (such as co-morbidities), there was an increased occurrence of a major complication (any one), pneumonia and infection with increased age at time of surgery. In order to differentiate the effect due to age and due to co-morbidities (which increased with age), multivariate regression was utilized. For the occurrence of any major complication, the presence of respiratory problems and previous infection were both more influential than age. Furthermore, when the effects of these two risk factors were controlled for, there no longer was an effect due to age. Discussion Older patients did not have an increased rate of major complications when compared to younger patients with similar respirator and infection history profiles

An eight-week-old boy developed severe thoracic spondylodiscitis following pneumonia and septicaemia. A delay in diagnosis resulted in complete destruction of the T4 and T5 vertebral bodies and adjacent discs, with a paraspinal abscess extending into the mediastinum and epidural space. Antibiotic treatment controlled the infection and the abscess was aspirated. At the age of six months, he underwent posterior spinal fusion in situ to stabilise the spine and prevent progressive kyphosis. At the age of 13 months, repeat imaging showed lack of anterior vertebral body re-growth and he underwent anterior spinal fusion from T3 to T6 and augmentation of the posterior fusion. At the age of five years, he had no symptoms and radiographs showed bony fusion across the affected levels. Spondylodiscitis should be included in the differential diagnosis of infants who present with severe illness and atypical symptoms. Delayed diagnosis can result in major spinal complications with a potentially fatal outcome

Historically rib fractures have been managed conservatively but over recent years evidence has continued to grow in support of fixation in select cases. Rib fractures can affect patients’ ability to adequately ventilate and increase the morbidity and mortality of patients with multiple injuries. There is increasing evidence that rib fracture fixation in certain patients is of benefit, reducing length of stay both in the Intensive Care Unit (ICU) and overall hospital stay, as well as resulting in a decreased rate of tracheostomy and pneumonia. We commenced rib fracture fixation two years ago as a combined procedure between Trauma Orthopaedics and Cardiothoracic surgery for carefully identified patients. We instituted a multi-disciplinary decision making process involving the Orthopaedic, Cardiothoracic and ICU teams. We present the initial results for these patients. Fourteen patients with a total of 49 ribs were fixed between November 2015 and August 2017. Nine patients were acute and multiply injured, with five patients treated with delayed fixation for ventilation problems following non-union of existing fractures. The average length of stay was 13 days. Follow up is ongoing with a mean follow up of 192 days. There have been no deep infections or acute complications and no incidence of peri-operative pneumothorax in this initial cohort. There have been no deaths, and all of these patients have since been discharged to their own home. The initial outcomes following the introduction of this new procedure to our unit have been encouraging, although the long term results are awaited

The aim of this study was to examine the rates and potential risk factors for 28-day re-admission following a fracture of the hip at a high-volume tertiary care hospital. We retrospectively reviewed 467 consecutive patients with a fracture of the hip treated in the course of one year. Causes and risk factors for unplanned 28-day re-admissions were examined using univariate and multivariate analysis, including the difference in one-year mortality. A total of 55 patients (11.8%) were re-admitted within 28 days of discharge. The most common causes were pneumonia in 15 patients (27.3%), dehydration and renal dysfunction in ten (18.2%) and deteriorating mobility in ten (18.2%). A moderate correlation was found between chest infection during the initial admission and subsequent re-admission with pneumonia (r = 0.44, p < 0.001). A significantly higher mortality rate at one year was seen in the re-admission group (41.8% (23 of 55) vs 18.7% (77 of 412), p < 0.001). Logistic regression analysis identified advancing age, admission source, and the comorbidities of diabetes and neurological disorders as the strongest predictors for re-admission. Early re-admission following hip fracture surgery is predominantly due to medical causes and is associated with higher one-year mortality. The risk factors for re-admission can have implications for performance-based pay initiatives in the NHS. Multidisciplinary management in reducing post-operative active clinical problems may reduce early re-admission

Purpose. The objective of this meta-analysis was to compare the effects of early and delayed surgery on the risk of mortality, common post-operative complications, and length of hospital stay among elderly hip fracture patients. Methods. We searched MEDLINE and EMBASE for relevant prospective studies evaluating surgical delay in patients undergoing surgery for hip fractures published in all languages between 1966 and 2008. Two reviewers independently assessed methodological quality and extracted relevant data. Results. Of 1939 citations identified, 16 observational studies that included a total of 13,478 patients with complete mortality data (1764 total deaths) met our inclusion criteria. Irrespective of the cut-off for delay (24, 48, or 72 hours), earlier surgery (< 24, < 48, or < 72 hours) was significantly associated with a reduction in the risk of unadjusted one-year mortality (relative risk 0.55; 95% confidence interval, 0.40 to 0.75, p=0.0002) and adjusted mortality rates (relative risk 0.81; 95% confidence interval, 0.68 to 0.96, p=0.01). Based on unadjusted data, earlier surgery also reduced in-hospital pneumonia (relative risk 0.59; 95% confidence interval, 0.37 to 0.93, p=0.02), pressure sores (relative risk 0.48; 95% confidence interval, 0.34 to 0.69, p< 0.0001) and hospital stay (weighted mean difference 9.95 days; 95% confidence interval, 1.52 to 18.39, p=0.02). Conclusion. Earlier surgery was associated with a reduced risk of mortality, post-operative pneumonia, pressure sores, and length of hospital stay among elderly hip fracture patients. This suggests that it may be warranted to reduce surgical delays whenever possible. However, unadjusted analyses are certainly confounded, and residual confounding may be responsible for apparent effects in adjusted analyses. A definitive answer to this issue will require the conduct of a large randomised controlled trial to evaluate the effect of earlier surgery among patients admitted with a hip fracture

Patients who sustain hip fractures should be operated on within 24 hours of admission according to the Royal College Of Physician Guidelines. A delay to theatre of more than 4 days is associated with an increase in inpatient mortality. A high proportion of patients with hip fractures are elderly and take aspirin, clopidogrel or warfarin. A retrospective review of 100 patients admitted between December 2006 and July 2007 with a hip fracture was conducted. Our aims were to assess the proportion of patients taking antithrombotic medication, when the antithrombotic medication was stopped pre-operatively and see whether there was a delay to theatre. We also evaluated any association between patients taking antithrombotic medication and a return to theatre, post-operative morbidity and mortality and length of inpatient stay. 47 patients were taking aspirin, 1 was taking clopidogrel, 2 were on aspirin and clopidogrel and 3 patients were taking warfarin. The aspirin group had an increased delay to theatre compared to the no antithrombotic group, however, both groups had similar numbers operated on within 24 hours. 68% (32/47) patients had the aspirin stopped on the same day as the operation. 1 patient taking aspirin returned to theatre for evacuation of a haematoma. The main post-operative complication was pneumonia (n=9). 8 patients required a blood transfusion of which 5 were taking aspirin. The main causes of mortality were ischaemic heart disease (n=7) and pneumonia (n=5). The mean lengths of inpatient stay were 22.48 days in the aspirin group, 50 days in the aspirin and clopidogrel group, 66 days in the clopidogrel group, 24.33 in the warfarin group and 24.81 days in the no antithrombotic group. It is suggested from this small study that there is no advantage in stopping aspirin prior to hip fracture surgery. However, further studies need to be undertaken

Background: Polytrauma patients with bilateral femur shaft fractures are known to have a higher rate of complications when compared with those who have sustained unilateral fractures. The current study tests the hypothesis that the high incidence of posttraumatic complications in patients who have no severe head or chest injury is caused by accompanying injuries rather than by the additional femur fracture. Methods: Prospective cohort study. Inclusion criteria: Injury severity score > 16 points; No AIS score value of the head or chest > 3 points. Two study groups: a unilateral (group USF) (n=146) and a bilateral femur shaft fracture (group BSF) (n=29). A further differentiation was made according to the patient’s status. All patients underwent early (< 24 hours after injury) fixation of their extremity fractures. Endpoints monitored were: Pneumonia, Acute lung injury (ALI), Systemic inflammatory response syndrome (SIRS), Sepsis. Statistics: Pearson chi-square test for binary indicators of injury severity, regression analyses regarding clinical complications. Results: Patients with bilateral femur fractures exhibited a longer ICU stay (p< 0.01), a higher incidence of pneumonia (p< 0.02) and SIRS (p=0.04) than those with unilateral fractures. Following corrective analyses for injury severity, no differences in blood transfusion rates, length of ICU stay, or complications was observed. Patients in borderline condition spend significantly more time in the ICU in comparison to those in stable condition. For analyses predicting presence of systemic inflammatory response syndrome, only the variable indicating receipt of a blood transfusion upon admission to the hospital emerged as a significant predictor. Bilateral fracture patients who were in uncertain condition preoperatively, developed significantly more complications postoperatively(p=0.02). Conclusions: Polytrauma patients with bilateral femur shaft fractures have a similar clinical course as those with unilateral fractures when no significant head or chest injury is present. An increased incidence of systemic inflammatory response syndrome was associated with three variables: presence of borderline condition, hemothorax and requirement of blood transfusion. This may have important treatment implications, including the management of major fractures

Introduction. Hypoalbuminemia has previously been identified as an independent predictor of postoperative complications following total knee arthroplasty (TKA). Given the morbidity and financial burden associated with TKA complications, significant effort has gone into identifying patients at increased risk for perioperative complications. The American Society of Anesthesiologists (ASA) physical status score has been utilized for risk stratification of surgical patients for many years and is a measure of overall health. However, it is unclear how measures like albumin compare to the prognostic ability of this type of global health measure. This study aims to elucidate the utility of preoperative albumin compared with that of the ASA score in predicting complications following TKA. Methods. Patients undergoing TKA between 2005 and 2015 were identified using the American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) database. Patients were stratified based on preoperative hypoalbuminemia (<3.5 g/dL) and ASA score (≤ 2 vs. > 2). Multivariable regression analysis adjusted for age, sex, BMI, and smoking status was utilized to determine predictive potential of hypoalbuminemia and ASA score on each postoperative complication. Results. Of the 79,661 patients included in the cohort, 4.3% had preoperative hypoalbuminemia. Univariate regression analysis found significant predictive abilities of both serum albumin and ASA score on numerous postoperative complications, such as superficial infection, deep infection, MI, pneumonia, renal insufficiency, reintubation, transfusion, readmission, reoperation, and death. Interestingly, multivariable regression analysis demonstrated that hypoalbuminemia more robustly predicted postoperative deep infection than ASA. Discussion and Conclusion. Hypoalbuminemia and ASA each individually predict numerous postoperative complications following TKA. However, this study suggests that while ASA score more accurately predicts post-operative medical complications, hypoalbuminemia may be a more accurate predictor of periprosthetic infection following TKA. Ultimately, preoperative albumin should be incorporated in the pre-operative work-up routine to stratify patient risk, especially regarding postoperative infection

Purpose: Hip fractures are associated with a high rate of mortality and profound temporary and sometimes permanent impairment of independence and quality of life. While guidelines exist for the surgical treatment of hip fracture patients, the effect of surgical delay on mortality and other patient-important outcomes remains unclear. The objective of this systematic review and meta-analysis was to determine the effect of early surgery compared with delayed surgery on the risk of mortality, common postoperative complications, and length of hospital stay among elderly hip fracture patients. Method: We searched MEDLINE and EMBASE for relevant prospective studies evaluating surgical delay in patients undergoing surgery for hip fractures published in all languages between 1966 and 2008. We identified additional studies through contacting experts, as well as hand searches of the bibliographies of relevant articles and the archives of orthopaedic annual meetings. Two reviewers independently assessed methodological quality and extracted relevant data. When necessary, we contacted authors for clarification of study design or to provide additional data. Data were pooled by use of a DerSimonian and Laird random-effects model based on the inverse variance method. Results: Of 1917 citations identified, 16 observational studies, which included a total of 13,565 patients with complete mortality data, met our inclusion criteria. Irrespective of the cut-off for delay (24, 48, or 72 hours), earlier surgery (< 24, < 48, or < 72 hours) was significantly associated with a reduction in the risk of unadjusted one-year mortality (relative risk 0.55; 95% confidence interval, 0.40 to 0.75, p=0.0002) and adjusted mortality rates (relative risk 0.81; 95% confidence interval, 0.68 to 0.96, p=0.01). Earlier surgery also reduced in-hospital pneumonia (relative risk 0.59; 95% confidence interval, 0.37 to 0.93, p=0.02), pressure sores (relative risk 0.48; 95% confidence interval, 0.34 to 0.69, p< 0.0001) and hospital stay (weighted mean difference 9.95 days; 95% confidence interval, 1.52 to 18.39, p=0.02). Conclusion: Earlier surgery reduced the risk of mortality, postoperative pneumonia, pressure sores, and length of hospital stay among elderly hip fracture patients suggesting that it may be warranted to reduce administrative delays whenever possible. However, potential residual confounding of observational studies may limit any definitive conclusions

Introduction: The management of cervical spine fracture, subluxation or dislocation in the elderly may present difficulties in decision-making. Frequently, the elderly suffer from medical comorbidity and a limited physiological reserve, which need to be considered in deciding on surgical versus conservative management of fractures and dislocations. Debate exists regarding the merits of surgical versus nonsurgical management of these injuries. 1,. 2,. 4. Methods: Retrospective analysis of 16 patients with traumatic cervical spine fractures with or without dislocation or subluxation in patients greater than 65 years of age, spanning 1994 to the present were carried out. Success of spine stabilisation, time in hospital, ability to return to pre-injury function and medical or surgical complications were measured. Results: The average age of the patients was 76 years with a range of 67–86 years of age. A variety of cervical injuries and fixation methods were identified, the most common injury being odontoid fracture requiring transarticular screw fixation. One patient died eight days post-operatively of cardiac arrest and a second patient died of pneumonia. One other complication of wound hematoma while the patient was taking anticoagulation therapy occurred. All other patients were discharged independent in activities of daily living. There were no cases of failure of surgery to restore stability. No post-operative neurological deterioration in any of the patients occurred. Discussion: This study shows that surgical fixation of cervical fractures in the elderly can be performed as a safe and efficient form of management. Surgery decreases the period of both immobility and hospitalisation with subsequent decrease in the risk of complications such as deep vein thrombosis, pulmonary embolism and pneumonia. 3. Complications from immobilisation devices such as the halo-thoracic brace may also be avoided

Aims

To map literature on prognostic factors related to outcomes of revision total knee arthroplasty (rTKA), to identify extensively studied factors and to guide future research into what domains need further exploration.

Patients with bilateral femur shaft fractures are known to have a higher rate of complications when compared with those who have unilateral fractures. Many contributing factors have been considered responsible, however due to the heterogeneity of the studied populations solid conclusions cannot be substantiated. Patients included in our study were separated according to the presence of a unilateral (group USF) (n=146) versus bilateral femur shaft fracture (group BSF) (n=19)Endpoints of the study included the incidence of systemic (SIRS, Sepsis, Acute Lung Injuries) complications. The perioperative assessment included documentation of clinical and laboratory data assessing blood loss, coagulopathy, wound infection, and pneumonia. Local (wound infection, compartment syndrome etc.) and systemic complications (ALI, MOF, Sepsis) were documented. Statistical analyses were conducted to examine the relation between the occurrence of unilateral versus bilateral femoral fractures and variables indexing patient demographic characteristics and other indicators of initial injury severity. Independent sample t-tests were used to examine treatment group differences for variables that approximated a Gaussian distribution. For non-normal indicators of injury severity Mann-Whitney tests were performed. Pearson chi-square tests were performed for binary indicators of injury severity, except when expected cell counts did not exceed 5 participants. When this occurred, the Fisher exact test was used Evidence indicated that patients who suffered a bilateral femoral fracture were significantly more likely to have hemothorax and receive a blood transfusion upon admission to the hospital in comparison to patients who suffered a unilateral femoral fracture. Bivariate analyses also indicated that patients with bilateral femoral fractures exhibited a longer clinical recovery time and were more likely to experience clinical complications in comparison to those with unilateral fractures. However, there were no significant differences between the fracture groups in terms of the number of hours spent on a ventilator or the occurrence of pneumonia, acute lung injury, acute respiratory distress, sepsis, and multiple organ failure following surgery. Patients in borderline condition spent significantly more time in the ICU in comparison to those in stable condition. The high incidence of posttraumatic complications in poly-trauma patients with bilateral femur shaft fractures is caused by the accompanying injuries rather than by the additional femur fracture itself. It also documents that a thorough preoperative assessment can help differentiate those who have a high like hood of developing systemic complications from those who do not

Introduction. Aged trauma patients with proximal femur fractures are prone to various complications. They may be associated with their comorbidities which also need to be adressed. These complications limit the patient”s postoperative health status and subsequently their activity and independency. As an attempt to improve the postoperative management of aged hip fracture patients a better understanding of the postoperative condition in these patients is necessary. Therefore, this meta-analysis is intended to provide an overview of postoperative complications in the elderly hip fracture patients and to improve the understanding of an adequate postoperative management. Material and method. Medline was used to screen for studies reporting on the complication rates of hip fracture patients > 65 years. The search criteria were: “proximal femur fracture, elderly, complication”. In addition to surgical studies, internal medicine and geriatric studies were also included. Randomized studies, retrospective studies as well as observation studies were included. Furthermore, reoperation rates as well as treatment-related complications were recorded. The 1-year mortality was calculated as outcome parameter. Results. Overall 54 studies were enrolled, published between 2011 and 2016. The mean age of the 9812 patients was 81 years (65–99 years). Follow-up was at least one year. The reoperation rate after osteosynthesis of pertrochanteric femur fractures was 8.7%. The reoperation rate was dependent on the type of fracture and the surgical method. Pneumonia (9,5%) and urinary tract infections (27%) were the most common postoperative infections. With 23%, delirium was one of the most common medical complications. The 1-year mortality rate was 18.7%. Conclusion. Orthogeriatric patients represent a complex patient population. Addressing the special needs of elderly patients reduces postoperative complications. Establishing comanagement or orthogeriatric wards can also be helpful to manage comorbidities and postoperative complications. It is important to not only choose the proper surgical procedure but to monitor orthogeriatric patients closely during their hospitalization

Neurogenic heterotopic ossification (NHO) is a disorder of aberrant bone formation affecting one in five patients sustaining a spinal cord injury or traumatic brain injury. Ectopic bone forms around joints in characteristic patterns, causing pain and limiting movement especially around the hip and elbow. Clinical sequelae of neurogenic heterotopic ossification include urinary tract infection, pressure injuries, pneumonia and poor hygiene, making early diagnosis and treatment clinically compelling. However, diagnosis remains difficult with more investigation needed. Our pathophysiological understanding stems from mechanisms of basic bone formation enhanced by evidence of systemic influences from circulating humor factors and perhaps neurological ones. This increasing understanding guides our implementation of current prophylaxis and treatment including the use of non-steroidal anti-inflammatory drugs, bisphosphonates, radiation therapy and surgery and, importantly, should direct future, more effective ones

Aims

The aim of this study was to investigate the association between additional rehabilitation at the weekend, and in-hospital mortality and complications in patients with hip fracture who underwent surgery.

Aims

Factors associated with high mortality rates in geriatric hip fracture patients are frequently unmodifiable. Time to surgery, however, might be a modifiable factor of interest to optimize clinical outcomes after hip fracture surgery. This study aims to determine the influence of postponement of surgery due to non-medical reasons on clinical outcomes in acute hip fracture surgery.

Aims

The present study aimed to investigate whether patients with inflammatory bowel disease (IBD) undergoing joint arthroplasty have a higher incidence of adverse outcomes than those without IBD.

Hypothesis: In severely the injured, there has been a move away from early total care to staged physiological and anatomic reconstruction, damage control orthopaedics (DCO). This seeks to limit the magnitude of the second hit insult resulting from operative treatment after trauma, deferring complex reconstructive work until a later stage. For femoral shaft fracture, this entails initial external fixation, to provide early skeletal stabilisation, and subsequent conversion to an intramedullary nail (IMN). Materials and Methods: Patients with femoral shaft fracture, who underwent primary IMN or DCO between 1996 and 2002 were identified from our database. Those with New Injury Severity Score (NISS) < 20 were excluded. The systemic inflammatory response (SIRS) and Marshall multi-organ failure scores (MMOFS) were calculated every 12h for 4 days. These systems have been previously correlated with outcome and complications in critical care. Results: 174 patients were included. The mean SIRS score was higher at each time period post operatively in the IMN group (p < 0.01). The MMOFS was slightly higher at each point in the DCO group, (only sig. at 48h). There was a higher incidence of pneumonia and mortality (significant p < 0.02), ARDS and MOF (both n.s.) in the DCO group, this being attributable to the higher incidence of head and thoracic injury (AIS severity 2 or more). The mean peak post-operative SIRS score was significantly higher in the IMN group than in the DCO group, both at primary procedure and conversion, as was the time with SIRS score above 1. The pre-op and peak post-op SIRS score correlated with the peak post op MMOFS score (p 0.0002). The conversion pre-op SIRS score correlated with post-operative peak SIRS score and MMOFS score (p 0.0001). On average, a significant rise in the MMOFS score did not occur following the conversion procedure. Conclusion: It would appear that despite having significantly more severe injuries, patients in the DCO group had a smaller, shorter postoperative systemic inflammatory response and suffered only slightly more pronounced organ failure than the IMN group. They did suffer more complications, but this was only significant for pneumonia. DCO patients undergoing conversion whilst their SIRS score was raised suffered the most pronounced subsequent inflammatory response and rise in organ failure score

Aims

Traumatic central cord syndrome (CCS) typically follows a hyperextension injury and results in motor impairment affecting the upper limbs more than the lower, with occasional sensory impairment and urinary retention. Current evidence on mortality and long-term outcomes is limited. The primary aim of this study was to assess the five-year mortality of CCS, and to determine any difference in mortality between management groups or age.

Aims

Periprosthetic fractures (PPFs) around the knee are challenging injuries. This study aims to describe the characteristics of knee PPFs and the impact of patient demographics, fracture types, and management modalities on in-hospital mortality.

Aims

Periprosthetic joint infection (PJI) demonstrates the most feared complication after total joint replacement (TJR). The current work analyzes the demographic, comorbidity, and complication profiles of all patients who had in-hospital treatment due to PJI. Furthermore, it aims to evaluate the in-hospital mortality of patients with PJI and analyze possible risk factors in terms of secondary diagnosis, diagnostic procedures, and complications.

Contrary to NICE guidance there remains a role for Austin-Moore hemiarthroplasty (AM) for patients with significant pre-existing comorbidities who are at higher risk of death and complications following cemented hemiarthroplasty. We analysed prospectively-collected data comparing uncemented AM hemiarthroplasty in frail, poorly-mobile patients, and cemented hemiarthroplasty. We analysed age, pre-operative morbidity, duration of operation, death rate and complication rate. AM patients were significantly older with significantly higher ASA grades. It took significantly longer to optimise them before surgery. AM was significantly shorter to perform. There was no significant difference in complications requiring re-operation. Twice as many AM patients developed post-operative pneumonia despite absence of cement. Twice as many AM patients died after surgery and a significant proportion died within the first month despite no increased risk of repeat operation, shorter operating time and no risk of cement-disease. We infer that these patients would likely have fared badly had they undergone a longer, cemented procedure. A modern cemented prosthesis costs £691 more than AM. There exists a subset of patients within the neck of femur cohort who are significantly more unwell. Contrary to guidelines, we suggest that the cheaper, user-friendly Austin-Moore can be a reasonable prosthesis to use for this cohort

Abstract. In aged trauma patients the basic prerequisite is early mobilization and full weight-bearing, as immobilization can trigger various complications such as pressure ulcers, pneumonia, urinary tract infections and others. Mortality of elderly patients increases significantly in fracture patients with partial weight-bearing compared to populations with total weight-bearing. Besides the limited physical strength in these patients, partial-weight bearing is however frequently used for the aftercare of hip fracture patients. Therefore, the present study aims to evaluate mobility of aged hip fracture patients with regards to weight-bearing and postoperative mobility. Methods. An insole mobile force sensor was used to measure the post-operative weight-bearing by assessing the compressive forces between foot and shoe. Only patients (n=15) that suffered a trochanteric fracture >75 years of age were included and compared to a study group of patients (n=18) with fractures of the lower limb <40 years of age. Patients with cognitive disorders such as delirium and other diseases limiting the realization of partial weight-bearing were excluded. Both groups were instructed to maintain partial weight bearing of the affected limb following surgery. Following five days of training by our department of physiotherapy, the patients were requested to perform a gait analysis with the insole mobile force sensor. During gait analysis the maximum load was measured (kg) and the time over which the partial load could be maintained was determined. Results. None of the aged patients in the test group could meet the partial load at all times. 73.33% of patients (11 out of 15) exceeded the specified load by more than twice (> 40 kg). In the control group, 55.56% (10 of 18) of the patients were able to meet the partial load. A further 22.22% of the young patients (4 out of 18) were able to exceed only slightly (<120%, <24 kg). It was also shown that only 11.11% (2 of 18) put more than double of the allowed weight (> 40 kg) on the affected leg in the younger group. Only one of the aged patients was able to exceed the pre-determined weight-bearing restrictions for less than 10% of the measured time. In comparison, significantly more patients in the control group (88,89%; 16 of 18; p<0,05) were able to maintain the partial load for more than 90.0% of the time of gait analysis. Conclusion. Elderly patients seem to be unable to follow partial weight-bearing restrictions as proven in the present trial. As early mobilization of geriatric trauma patients is an important element for a successful rehabilitation, the relict of postoperative partial weight-bearing in these patients should be abandoned. Thus, the surgical therapy should allow immediate full weight bearing following surgery of aged hip fracture patients

Down syndrome (DS), is a genetic disorder caused by a third copy of the 21st chromosome (Trisomy 21), featuring typical facial characteristics, growth delays and varying degrees of intellectual disability. Some degree of immune deficiency is variably present. Multiple orthopaedic conditions are associated, including stunted growth (90%), ligamentous laxity (90%), low muscle tone (80%), hand and foot deformities (60%), hip instability (30%), and spinal abnormalities including atlanto-axial instability (20%) and scoliosis. Hip disease severity varies and follows a variable time course. Rarely a child presents with DDH, but during the first 2 years the hips are characteristically stable but hypermobile with well-formed acetabulae. Spontaneous subluxation or dislocation after 2 presents with painless clicking, limping or giving way. Acute dislocation is associated with moderate pain, increased limp and reduced activity following minor trauma. Hips are reducible under anesthesia, but recurrence is common. Eventually concentric reduction becomes rarer and radiographic dysplasia develops. Pathology includes: a thin, weak fibrous capsule, moderate to severe femoral neck anteversion and a posterior superior acetabular rim deficiency. A number of femoral and acetabular osteotomies have been reported to treat the dysplasia, with acetabular redirection appearing to be most successful. However, surgery can be associated with a relatively high infection rate (20%). Additionally, symptomatic femoral head avascular necrosis can occur as a result of slipped capital femoral epiphysis. Untreated dysplasia patients can walk with a limp and little pain into the early twenties even with fixed dislocation. Pain and decreasing hip function is commonly seen as the patient enters adult life. Occasionally the hip instability begins after skeletal maturity. Total hip arthroplasty (THA) is the standard treatment when sufficient symptoms have developed. The clinical outcomes of 42 THAs in patients with Down syndrome were all successfully treated with standard components. The use of constrained liners to treat intra-operative instability occurred in eight hips and survival rates were noted between 81% and 100% at a mean follow-up of 105 months (6 – 292 months). A more recent study of 241 patients with Down syndrome and a matched 723-patient cohort from the Nationwide Inpatient Sample compared the incidence of peri-operative medical and surgical complications in those who underwent THA. Compared to matched controls, Down syndrome patients had an increased risk of complications: peri-operative (OR, 4.33; P<.001), medical (UTI & Pneumonia OR, 4.59; P<.001) and surgical (bleeding OR, 3.51; P<.001), Mean LOS was 26% longer (P<.001). While these patients can be challenging to treat, excellent surgical technique and selective use of acetabular constraint can reliably provide patients with excellent pain-relief and improved function. Pre-operative education of all clinical decision makers should also reinforce the increased risk of medical and surgical complications (wound hemorrhage), and lengths of stay compared to the general population

Aims

The use of multimodal non-opioid analgesia in hip fractures, specifically acetaminophen combined with non-steroidal anti-inflammatory drugs (NSAIDs), has been increasing. However, the effectiveness and safety of this approach remain unclear. This study aimed to compare postoperative outcomes among patients with hip fractures who preoperatively received either acetaminophen combined with NSAIDs, NSAIDs alone, or acetaminophen alone.

Among the most critical factors to reducing the risk of infection include the use of pre-incisional antibiotics, appropriate skin preparation with clippers (as opposed to a razor for hair removal) and the use of an alcohol-based skin preparation. Host factors are also likewise critically important including obesity, diabetes, inflammatory arthritis, renal insufficiency, skin disorders and patients who are otherwise immune-compromised. If modifiable risk factors are identified, it would seem reasonable to delay elective surgery until these can be optimised. One other factor to consider is the nutritional status of the patient. In a study of 501 consecutive revisions, we found that serological markers suggestive of malnutrition (albumin, transferrin or total lymphocyte count) were extremely common. Specifically, 53% of patients who presented for treatment of a chronic infection had at least one marker for malnutrition, compared to 33% in the group of patients undergoing revision for an aseptic reason. Malnutrition was found to be an independent risk factor for septic failure (p < 0.001 and OR 2.1). Interestingly, malnutrition was most common among patients of normal weight but was also common among obese patients (so-called “paradoxical” malnutrition). What was more disturbing, however, was that of those patients undergoing an aseptic revision, serum markers of malnutrition were associated with a 6× risk of acute post-operative infection complicating the patient's aseptic revision. We have confirmed this association using the NSQIP database where hypoalbuminemia was associated with a higher risk of infection, pneumonia and readmission. At our center, we also have studied the use of dilute betadine at the end of the case, prior to wound closure, in an attempt to decrease the load of bacteria in the wound. In a retrospective review the prevalence of acute post-operative infection was reduced from just under 1% (18/1862) to 0.15% (1 of 688; p = 0.04). It is critical that the betadine utilised be STERILE and the dilution we use is 0.35% made by diluting 17.5cc of 10% povidone-iodine paint in 500cc of normal saline

Aims

Periprosthetic joint infection (PJI) in total hip arthroplasty in the elderly may occur but has been subject to limited investigation. This study analyzed infection characteristics, surgical outcomes, and perioperative complications of octogenarians undergoing treatment for PJI in a single university-based institution.

Aims

The aim of this study was to characterize the influence of social deprivation on the rate of complications, readmissions, and revisions following primary total shoulder arthroplasty (TSA), using the Social Deprivation Index (SDI). The SDI is a composite measurement, in percentages, of seven demographic characteristics: living in poverty, with < 12 years of education, single-parent households, living in rented or overcrowded housing, households without a car, and unemployed adults aged < 65 years.

Aims

The purpose of this study was to compare reoperation and revision rates of double plating (DP), single plating using a lateral locking plate (SP), or distal femoral arthroplasty (DFA) for the treatment of periprosthetic distal femur fractures (PDFFs).

Aims

In cases of severe periprosthetic joint infection (PJI) of the knee, salvage procedures such as knee arthrodesis (KA) or above-knee amputation (AKA) must be considered. As both treatments result in limitations in quality of life (QoL), we aimed to compare outcomes and factors influencing complication rates, mortality, and mobility.

Malnutrition is a potentially modifiable risk factor that may contribute to complications following geriatric hip fracture surgery. The purpose of this study was to investigate the association between preoperative hypoalbuminemia, a marker for malnutrition, and complications during the thirty days following surgery for geriatric hip fracture. The American College of Surgeons National Surgical Quality Improvement Program was used to conduct a retrospective cohort study of geriatric patients (>65 years) undergoing surgery for hip fracture. Patients without preoperative serum albumin concentration were excluded. Outcomes were compared between patients with and without hypoalbuminemia (defined as serum albumin concentration <3.5g/dL). All comparisons were adjusted for baseline differences between populations. 17,651 Patients were identified. Of these, 8,272 (46.9%) underwent hemiarthroplasty, 759 (4.3%) total joint arthroplasty, 324 (1.9%) percutaneous fixation, 2,445 (13.9%) plate/screw fixation, and 5,833 (33.1%) intramedullary fixation. The prevalence of hypoalbuminemia was 45.9% (Figure 1). The risk for death was strongly associated with serum albumin concentration, with a linear increase in risk observed as albumin fell below 3.5 g/dL (p<0.001; Figure 2). Following adjustment for all demographic, comorbidity, and procedural characteristics, patients with hypoalbuminemia had higher rates of death (9.94% versus 5.53%, adjusted relative risk [RR]=1.54, p<0.001), pneumonia (5.30% versus 3.77%, adjusted RR=1.20, p=0.012), sepsis (1.19% versus 0.53%, adjusted RR=1.90, p<0.001), and hospital readmission (10.91% versus 9.03%, adjusted RR=1.11, p<0.036; Table 1). The present study suggests that hypoalbuminemia is a powerful independent risk factor for death following surgery for geriatric hip fracture. This association persists over-and-above any associations of death with age, sex, body mass index, and comorbidities. Based on these data, we propose that the nutritional status of hip fracture patients should receive greater attention, and that randomized trials testing for efficacy of aggressive postoperative nutritional interventions may be warranted.

Hip fractures are among the most common orthopaedic injuries and represent a growing burden on healthcare as our population ages. Despite improvements in preoperative optimisation, surgical technique and postoperative care, complication rates remain high. Time to surgery is one of the few variables that may be influenced by the medical team. The aim of the present study was to evaluate the impact of time to surgery on mortality and major complications following surgical fixation of hip fractures. Utilising the American College of Surgeons' National Quality Improvement Program (NSQIP) database, we analysed all hip fractures (femoral neck, inter-trochanteric, and sub-trochanteric) treated from 2011 to 2013 inclusively. We divided patients into three groups based on time to surgery: less than one day (<24h), one to two days (24–48h), and two to five days (48–120h). Baseline characteristics were compared between groups and a multivariate analysis performed to compare 30-day mortality and major complications (return to surgery, deep wound infection, pneumonia, pulmonary embolus, acute renal failure, cerebrovascular accident, cardiac arrest, myocardial infarction, or coma) between groups. A total of 14,730 patients underwent surgical fixation of a hip fracture and were included in our analysis. There were 3,475 (24%) treated <24h, 9,960 (67%) treated 24–48h, and 1,295 (9%) treated 48–120h. Thirty-day mortality and major complication rates were 5.0% and 6.2% for the <24h group, 5.3% and 7.0% for the 24–48h group, 7.9% and 9.7% for the 48–120h group respectively. After controlling for baseline demographic differences between groups (age, sex, race) as well as pertinent comorbidities (diabetes, dyspnea, chronic obstructive pulmonary disease, chronic steroid use, hypertension, cancer, bleeding disorders, and renal failure), time to surgery beyond 48h resulted in greater odds of both mortality (1.45, 95%CI 1.10–1.91) and major complications (1.45, 95%CI 1.12–1.84). Time to surgery is one of the few variables that can be influenced by timely medical assessment and access to the operation room. Expediting surgery within 48h of hip fracture is of paramount importance as it may significantly reduce the risk of mortality as well as major complications

Aims

Femoral periprosthetic fractures are rising in incidence. Their management is complex and carries a high associated mortality. Unlike native hip fractures, there are no guidelines advising on time to theatre in this group. We aim to determine whether delaying surgical intervention influences morbidity or mortality in femoral periprosthetic fractures.

Aims

Surgery is often delayed in patients who sustain a hip fracture and are treated with a total hip arthroplasty (THA), in order to await appropriate surgical expertise. There are established links between delay and poorer outcomes in all patients with a hip fracture, but there is little information about the impact of delay in the less frail patients who undergo THA. The aim of this study was to investigate the influence of delayed surgery on outcomes in these patients.

Almost any kind of bacteria can be involved in prosthetic joint infections (PJI). In 2014 we collected data on 3 patients presenting with hip or knee pain and radiological signs of prosthetic joint mobilization without any other clinical or biochemical suspect of infection. Interestingly, in all cases we isolated bacteria very rarely involved in human infections: Cupriavidus pauculus, Ralstonia paucula and Neisseria flavescens. Both Cupriavidus pauculus and Ralstonia paucula are Gram negative environmental bacteria which can contaminate water (tap, pool and mineral) and have been isolated from a variety of human clinical sources including blood, wounds, sputum, urine, eye, throat and peritoneal fluid, as non pathogenic flora. In such two patients we were able to cure the infection with quinolones (both strains were sensible). Neisseria species are Gram-negative bacteria included among the proteobacteria. Neisseria flavescens is often found in the upper respiratory tract and oropharynx of humans, rarely associated with infectious process (necrotizing pneumonia and empyema). In this last patient we successfully used piperacillin-tazobactam i.v. during hospitalization and shifted to amoxicillin-clavulanate per os at discharge. In conclusion, any bacteria can induce PJI: in some cases pre-operative blood tests are normal and therefore useless. We need new tests to overcome this diagnostic problem (such as alpha-defensin) and we must check on rare bacteria prolonging incubation to a more extended period of time (as in Propionebacterium acnes or Mycobacterium spp) and/or sending samples to specialized laboratories.

Aims

Historically, patients undergoing surgery for adolescent idiopathic scoliosis (AIS) have been nursed postoperatively in a critical care (CC) setting because of the challenges posed by prone positioning, extensive exposures, prolonged operating times, significant blood loss, major intraoperative fluid shifts, cardiopulmonary complications, and difficulty in postoperative pain management. The primary aim of this paper was to determine whether a scoring system, which uses Cobb angle, forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and number of levels to be fused, is a valid method of predicting the need for postoperative critical care in AIS patients who are to undergo scoliosis correction with posterior spinal fusion (PSF).

Aims

To identify factors influencing clinicians’ decisions to undertake a nonoperative hip fracture management approach among older people, and to determine whether there is global heterogeneity regarding these factors between clinicians from high-income countries (HIC) and low- and middle-income countries (LMIC).

The benefit of using a long intramedullary device for the treatment of geriatric intertrochanteric hip fractures is unknown. The InterTAN device (Smith and Nephew, Memphis TN) is offered in either Short (180–200 mm) or Long (260–460 mm) constructs and was designed to provide stable compression across primary intertrochanteric fracture fragments. The objective of our study was to determine whether Short InterTANs are equivalent to Long InterTANs in terms of functional and adverse outcomes for the treatment of geriatric intertrochanteric hip fractures. 108 patients with OTA classification 31A–1 and 31A–2 intertrochanteric hip fractures were included in our study and prospectively followed at one of four Canadian Level-1 Trauma Centres. Our primary outcomes included two validated primary outcome measures: the Functional Independence Measure (FIM), to measure function, and the Timed Up and Go (TUG), to measure motor performance. Secondary outcome measures included blood loss, length of procedure, length of stay and adverse events. A pre-injury FIM was measured by retrospective recall and all postoperative outcomes were assessed on postoperative day 3, at discharge, at 6 weeks, 3 months, 6 months and 12 months postoperatively. Unpaired t-tests and Chi-square tests were used for the comparison of continuous and categorical variables respectively between the Short and Long InterTAN groups. A statistically significant difference was defined as p<0.05. Our study included 71 Short InterTAN and 37 Long InterTAN patients with 31A–1 and 31A–2 intertrochanteric hip fractures. Age, sex, BMI, side, living status and comorbidities were similar between the two groups. The mean operative time was significantly lower in the Short InterTAN group (61 mins) as compared to the Long InterTAN group (71 mins)(p0.05). There were 5 periprosthetic femur fractures in the short InterTAN group versus 1 in the long InterTAN group. Non-mechanical adverse outcomes such as myocardial infarction, pulmonary embolism, urinary tract infections, pneumonia and death all had similar incidence rates between the two InterTAN groups. Both the Short and Long InterTAN patient cohorts displayed similar improvements in performance and overall function over the course of a year following intertrochanteric hip fracture fixation. The recorded operative times for Short InterTAN fixation were significantly shorter than those recorded for the Long InterTAN patients. Alternatively, a significantly higher proportion of Short InterTAN patients sustained periprosthetic femur fractures within a year of implantation as compared to the Long InterTAN group

Aims

Due to their radiolucency and favourable mechanical properties, carbon fibre nails may be a preferable alternative to titanium nails for oncology patients. We aim to compare the surgical characteristics and short-term results of patients who underwent intramedullary fixation with either a titanium or carbon fibre nail for pathological long-bone fracture.

Aims

This study aimed to explore the diagnostic value of synovial fluid neutrophil extracellular traps (SF-NETs) in periprosthetic joint infection (PJI) diagnosis, and compare it with that of microbial culture, serum ESR and CRP, synovial white blood cell (WBC) count, and polymorphonuclear neutrophil percentage (PMN%).

Aims

Professional dancers represent a unique patient population in the setting of hip arthroplasty, given the high degree of hip strength and mobility required by their profession. We sought to determine the clinical outcomes and ability to return to professional dance after total hip arthroplasty (THA) or hip resurfacing arthroplasty (HRA).

Aims

The standard of wide tumour-like resection for chronic osteomyelitis (COM) has been challenged recently by adequate debridement. This paper reviews the evolution of surgical debridement for long bone COM, and presents the outcome of adequate debridement in a tertiary bone infection unit.

Aims

Gram-negative periprosthetic joint infection (PJI) has been poorly studied despite its rapidly increasing incidence. Treatment with one-stage revision using intra-articular (IA) infusion of antibiotics may offer a reasonable alternative with a distinct advantage of providing a means of delivering the drug in high concentrations. Carbapenems are regarded as the last line of defense against severe Gram-negative or polymicrobial infection. This study presents the results of one-stage revision using intra-articular carbapenem infusion for treating Gram-negative PJI, and analyzes the characteristics of bacteria distribution and drug sensitivity.

Aims

We assessed the value of the Clinical Frailty Scale (CFS) in the prediction of adverse outcome after hip fracture.

Aims

The number of patients undergoing surgery for degenerative cervical radiculopathy has increased. In many countries, public hospitals have limited capacity. This has resulted in long waiting times for elective treatment and a need for supplementary private healthcare. It is uncertain whether the management of patients and the outcome of treatment are equivalent in public and private hospitals. The aim of this study was to compare the management and patient-reported outcomes among patients who underwent surgery for degenerative cervical radiculopathy in public and private hospitals in Norway, and to assess whether the effectiveness of the treatment was equivalent.

Aims

The aims of this study were to determine the incidence and factors for developing periprosthetic joint infection (PJI) following hemiarthroplasty (HA) for hip fracture, and to evaluate treatment outcome and identify factors associated with treatment outcome.

Aims

To evaluate if, for orthopaedic trainees, additional cadaveric simulation training or standard training alone yields superior radiological and clinical outcomes in patients undergoing dynamic hip screw (DHS) fixation or hemiarthroplasty for hip fracture.

Aims

To assess the feasibility of a randomized controlled trial (RCT) that compares three treatments for acetabular fractures in older patients: surgical fixation, surgical fixation and hip arthroplasty (fix-and-replace), and non-surgical treatment.

Aims

The modern prevalence of primary tumours causing metastatic bone disease is ill-defined in the oncological literature. Therefore, the purpose of this study is to identify the prevalence of primary tumours in the setting of metastatic bone disease, as well as reported rates of pathological fracture, postoperative complications, 90-day mortality, and 360-day mortality for each primary tumour subtype.

Aims

To assess the cost-effectiveness of a two-layer compression bandage versus a standard wool and crepe bandage following total knee arthroplasty, using patient-level data from the Knee Replacement Bandage Study (KReBS).

Aims

Patients with proximal femoral fractures (PFFs) are often multimorbid, thus unplanned readmissions following surgery are common. We therefore aimed to analyze 30-day and one-year readmission rates, reasons for, and factors associated with, readmission risk in a cohort of patients with surgically treated PFFs across Austria.

Utilising the (ACS-NSQIP) database, we aimed to evaluate the impact of resident level of training on surgical outcome following (TKA) and to compare the US and Canadian health care training system in regards to 30 days postoperative complications and readmission rates. Using the (CPT) codes we selected from the 2011 and 2012 NSQIP database elective primary TKA with the resident surgeon involved. Of these, all cases with a primary diagnosis code of infection, fracture, mechanical complication, or malignancy and all cases with incomplete or incongruous demographic information were excluded. We also eliminated all the cases with the Attending not present. A total of 2513 cases were included in the study. The cases were stratified into three groups according to the postgraduate level of training {PGY 1 to 3 (junior resident), PGY 4 to 5 (senior resident), and fellow}. Univariate analysis of all patient demographics, comorbidities, intra and postoperative variables, length of surgery, hospital stay and 30 days readmission rates were conducted in order to identify differences between the groups. A standard student's t test was used for continuous variables while the ChiSquared was used for categorical variables. Multivariable logistic regression models were created to assess the independent effect of the resident level of training on the 30 days major complication and re-admission rates while controlling for all other variables. We identified, 854 (34%) TKAs with junior residents, 1013 (40%) TKAs with senior residents and 646 (26%) TKAs with fellows' participation. Junior residents had a significant (p<0.0001) longer operative time (107±36 minutes) compared with senior residents and fellows. Length of hospital stay was longer in the fellow group probably because of their involvement in more complicated cases. Additionally, an increased number of blood transfusion was observed for the cases performed with involvement of senior residents when compared with the other two groups. However, no significant difference in complications was observed across training levels. When comparing US (2074 TKAs) versus Canada (423 TKAs) cases, we found that fellow contribution to TKA surgeries is higher in Canada. The occurrence of pulmonary embolism and pneumonia was three times higher in Canada cases, while blood transfusion was more frequent in US. Increased operative time, ASA class, age, diabetes, percutaneous cardiac intervention, and steroid use were all independent risk factors for complications following primary TKA. However, no significant difference was observed between the two groups with regards to major complications suggesting no difference between Canadian and American training system in regards to post operative complication. Our results support previous study study indicating that involvement of residents did not affect the surgical outcome within 30 days when compared to cases with no resident involvement. Our study suggests that resident level does not independently increase the risk of short term complications and support continuing involvement of junior trainees in TKA

Aims

There is little published on the outcomes after restarting elective orthopaedic procedures following cessation of surgery due to the COVID-19 pandemic. During the pandemic, the reported perioperative mortality in patients who acquired SARS-CoV-2 infection while undergoing elective orthopaedic surgery was 18% to 20%. The aim of this study is to report the surgical outcomes, complications, and risk of developing COVID-19 in 2,316 consecutive patients who underwent elective orthopaedic surgery in the latter part of 2020 and comparing it to the same, pre-pandemic, period in 2019.

Aims

The purpose of this study was to compare the clinical outcomes, mortalities, implant survival rates, and complications of total knee arthroplasty (TKA) in patients with or without hepatitis B virus (HBV) infection over at least ten years of follow-up.

Propionibacterium acnes is an emerging pathogen especially in orthopedic implant infection. Aim of this study was to investigate P. acnes phylogeny and to screen for virulence factors among a large collection of clinical isolates involved in spine material infections, arthroplasty infections and acne lesions. 88 P. acnes clinical isolates were collected between January 2003 and December 2014 at Nantes University Hospital (France). Fifty-eight isolates came from spine infections, 14 from prosthetic infections (knee, hip or shoulder), 14 from acne lesions and two reference strains (ATCC11827 and ATCC6919). Implant associated infections were confirmed using Infectious Diseases Society of America criteria for bone and joint infections. Phylotypes and Multi-Locus Sequence Typing (MLST) was carried out on all isolates as described by Lomholt et al. All isolates were tested by established PCR-based assays for 21 putative virulence factor genes characteristic of P. acnes. MLST analysis revealed an association between clonal complexes (CCs) and origin of P. acnes isolates (p = 0,027). Regarding CCs distribution between different origins, CC36 and phylotype II P. acnes isolates are more frequently observed in prosthetic joint infections. On the other hand, CC18 (IA) and CC28 (IB) P. acnes isolates are more frequently involved in spine infections and acne lesions. Among all virulence factors screened, hyaluronate lyase gene was only present in CC36 and phylotype II P acnes isolates. Other virulence factors were present in all isolates, whatever their origin or CC. Regarding molecular typing results, P. acnes involved in spine infections seem to have a skin origin (same CC as isolates from acne lesion). Interestingly, the origin of prosthetic joint infection isolates seems different and they all carry one more virulence factor. Hyaluronate lyase (Hyl) is a major surface protein of P. acnes with potential antigenetically variable properties that might be essential for P. acnes virulence. Increased tissue permeability caused by the action of hyaluronidase on the extracellular matrix appears to play a role in wound infections, pneumonia, and other sepsis such as bacteremia and meningitis. It could be also take a prominent part in P. acnes prosthetic joint infection pathogenesis

Aims

Although there is increasing legalization of the use of cannabis in the USA, few well-powered studies have evaluated the association between cannabis use disorder and outcomes following primary total hip arthroplasty (THA). Thus, the aim of this study was to determine whether patients who use cannabis and undergo primary THA have higher rates of in-hospital length of stay (LOS), medical complications, implant-related complications, and costs.

Diagnosis, treatment and outcome in systemic infection caused by Coccidioides Immitis in a non endemic region. First case in Spain. 71 year old patient. Symptoms: stomach aches, tiredness and weight loss of 14kg. Imaging Investigations: Abdominal pelvic US and Gastroscopy were performed as cancer was suspected. This study showed a bilateral suprarrenal mass. Fearing a pulmonary mass a Thoracic Scan was requested. Results proved mediastinal and axillary nodes. Also found was interstitial illness which lead to a working diagnosis of Granulomatous Lymphangitis. BIOPSIES: An axillary lymph node, suprarrenal gland and pulmonary tissues. ANATOMOPATHOLOGY: Necrotising Granulomatous Lymphadenitis. DIFFERENTIAL DIAGNOSIS: TBC, Sarcoidosis and Autoinmune illnesses. SAMPLE CULTURES were repeatedly negative for funghi, bacteria and Mycobacterium. DIAGNOSIS The patient was subsequently he was commenced on Substitute Hormonal Therapy with improvement of symptoms. MANAGEMENT: Due to a gonarthrosis he required Total Knee Arthroplastia. During surgery a prominent SINOVITIS was noticed, with anatomopathology results of Chronic Necrotising Granulomatous Sinovitis with lymphoid folicules. FOLLOW UP: 7 years after the patient attends A&E with signs of infection on the replaced knee. A bacterial infection is suspected and the patient is admitted into hospital for the replacement extraction, cement substitution with Gentamicin and iv antibiotherapy with LEVOFLOXACIN. His symptoms improved up to a month when he returned to A&E with similar presentation THE PATIENT IS ADMITTED ONCE MORE FOR SURGERY:. Sample Cultures from the prosthesis showed positive growth for Coccidiodes Immitis. Article Reviews provided us with brand new information. A new approach was taken and anamnesis was geared towards finding out a possible contact with the funghi in the endemic region. It appeared that the patient had worked as a Shepherd for four years (1957–1961) in Bakersfield. A Southern Californian region north to LA and under San Francisco. After all, he was admitted for 25 days in a local hospital for pneumonia. DIAGNOSIS WAS REACHED thanks to these findings. The old spacer wasswapped for a Cement Spacer with Amphotericin B 250 mg. Oral treatment with FLUCONAZOL 400 mg/day was associated and after a few days changed to ITRACONAZOL 200 mg/12 hours orally. The patient improved local and systemically. After a few months he evolved as planned and now has a good general and local condition with normal biochemistry results. A final ARTHRODESIS was performed. It's quite likely that he may require long life therapy with Antifungals to avoid reactivations. We highlight the originality of the case, as the first diagnosis of articular Coccidioides diagnosed in Spain, and its successful outcome with prosthetic replacement rebound and chronic antifungal therapy

Aims

The aim of the HIPGEN consortium is to develop the first cell therapy product for hip fracture patients using PLacental-eXpanded (PLX-PAD) stromal cells.

Aims

The aim of this study was to investigate the outcome of periprosthetic fractures of the humerus and to assess the uniformity of the classifications used for these fractures (including those around elbow and/or shoulder arthroplasties) by performing a systematic review of the literature.

Introduction. A fractured hip is the commonest cause of injury related death in the UK. Prompt surgery has been found to improve pain scores and reduce the length of hospital stay, risk of decubitus ulcer formation and mortality rates. The hip fracture Best Practice Tariff (BPT) aims to improve these outcomes by financially compensating services, which deliver hip fracture surgery within 36 hours of admission. Ensuring that delays are reserved for patients with conditions which compromise survival, but are responsive to medical optimisation, would facilitate enhanced outcomes and help to achieve the 36-hour target. We aimed to identify medical conditions associated with patients failing to achieve the 36-hour cut off, and evaluated whether these were justified by calculating their associated mortality risk. Methods. Prospectively collected data from the National Hip Fracture Database (NHFD) and inpatient hospital records and blood results from a single major trauma centre were obtained. Complete data sets from 1361 patients were available for analysis. Medical conditions contributing to surgical delay beyond the BPPT (Best Practice Tariff Target) 36-hour cut off, were identified and analysed using univariate and multivariate regression analyses, whilst adjusting for covariates. The mortality risk associated with each factor contributing to surgical delay was then calculated using univariate and hierarchical regression techniques. Results. A total 1,361 patients underwent hip fracture surgery, of which 537 patients (39.5%) received surgery within 36- hours of admission. The overall median time to surgery from presentation was 23 hours (range 3–36) in patients who did (group 1) and 72 hours (range 36–774) in those who did not (group 2) receive timely surgery. There was no difference between the two groups with respect to age, gender, walking ability, fracture pattern and ASA grade. Following univariate analysis, seven variables including admission source, history of dementia, ischaemic heart disease, MI, cerebrovascular accidents (CVA), urinary tract infections and hyponatraemia met criteria for inclusion into the Cox regression model. The model thereafter revealed only hyponatraemia to be a significant determinant of delay to surgery beyond 36 hours with a covariate adjusted relative risk (RR) 1.24 (95% CI 1.06 – 1.44, p=0.006). The overall 30- day mortality in our cohort of hip fracture patients was 9.0%. The commonest cause of death was pneumonia (37%). A second stage hierarchical cox model failed to demonstrate hyponatraemia as being a predictor of 30- day mortality after adjusting for significant co-variants (RR=0.944, CI 95% 0.616–1.447, p=0.793). Conclusions. Hip fracture surgery should not be delayed in the presence of non-severe and isolated hyponatraemia. Instead surgical delay should be reserved for medical conditions, which contribute to mortality and are optimisable

The majority of hip fracture patients receive operative treatment, although the National Hip Fracture Database (NHFD) 2012 suggest 2.6% were treated conservatively. One of only a few published reports on the outcomes of these patients has demonstrated that mortality rates beyond 30 days remain comparable to patients receiving surgery. We have assessed the outcomes of conservatively managed patients in our unit. Patients treated conservatively at our hospital between 2010 and 2012 inclusive were identified using the NHFD. Data collection included mobility status, ASA grade, Nottingham Hip Fracture Score (NHFS), mortality (30 days and 1 year) and pain scores. The study group (N=31) had a mean age 85, mean ASA was 4 and mean NHFS mortality risk 21.3%. Morbidity included one case of pneumonia and one infection from another source, however there were no pressure sores or VTE. Three patients later received surgery once their health had improved. Pain control was achieved in 91% patients (21/23) and although mobility decreased, 34.8% of patients were able to mobilise with either two aids or a frame. Given the selection bias for conservative treatment in unwell patients, the higher mortality figure is not unexpected. Although the 30 day mortality data is higher than the national average for operative management, those patients surviving 30 days have a mortality similar to those managed operatively. Despite mobility decreasing from the pre-admission status, a significant number of patients were pain free and could mobilise. Therefore conservative management can produce acceptable results in these patients

Aims

The proportion of arthroplasties performed in the ambulatory setting has increased considerably. However, there are concerns whether same-day discharge may increase the risk of complications. The aim of this study was to compare 90-day outcomes between inpatient arthroplasties and outpatient arthroplasties performed at an ambulatory surgery centre (ASC), and determine whether there is a learning curve associated with performing athroplasties in an ASC.

Introduction. The incidence of distal femoral fractures amongst elderly patients is likely to rise due to increased life expectancy. This study reports on the outcome of a series of distal femoral fractures treated by retrograde femoral nailing and then to compare the results for these patients with a series of patients with a proximal femoral fracture. Materials and/Methods. In this longitudinal cohort study, 36 patients with extra-articular distal femoral fractures were treated with a solid retrograde femoral nail. Data was collected prospectively and then compared to proximal femoral fractures (2426) treated by the same surgeon treated over the same time period. Results. Within the distal femoral group 97% of the patients were female, with a mean age of 81 years. The mean length of hospital stay amongst the distal femoral group was slightly higher (19 days) compared to the proximal femoral group (18 days). All the post-operative complications were higher amongst the distal femoral group which included deep vein thrombosis 8% vs 2%, pneumonia 5% vs 3%, superficial wound infection 5% vs 3% and deep wound infection 2% vs 1%. 5% of patients in the proximal femoral group required revision surgery whereas none in the distal femoral group did. The survival analysis curve indicated to an increased trend in mortality amongst the distal femoral group however due to the small sample size this did not reach statistical significance. Conclusions. Our study shows that there is a significant morbidity and mortality amongst patients who have sustained a distal femoral fracture. Given the significant risk that elderly patients have we propose that distal femoral fractures should be treated with prompt surgical fixation with an emphasis on early rehabilitation and safe discharge

Aims

Access to total knee arthroplasty (TKA) is sometimes restricted for patients with severe obesity (BMI ≥ 40 kg/m²). This study compares the cost per quality-adjusted life year (QALY) associated with TKA in patients with a BMI above and below 40 kg/m² to examine whether this is supported.

Aims

Endoprosthetic reconstruction with a distal femoral arthroplasty (DFA) can be used to treat distal femoral bone loss from oncological and non-oncological causes. This study reports the short-term implant survivorship, complications, and risk factors for patients who underwent DFA for non-neoplastic indications.

Aims

The aim of this study was to report the incidence of implant-related complications, further operations, and their influence on the outcome in a series of patients who underwent primary reverse total shoulder arthroplasty (RTSA).

Objective. Posterior vertebral column resection (PVCR) is indicated in the management of severe rigid spine deformities. It is a complex surgical procedure and is only performed in a few spine centres due to the technical expertise required and associated risk. The purpose of this study is to review the indications, surgical challenges and outcomes of patients undergoing PVCR. Methods. 12 patients with severe spinal deformities who underwent PVCR were retrospectively reviewed after a follow-up of 2 years. Surgery was performed with the aid of motor evoked spinal cord monitoring and cellsaver when available. The average surgical duration was 310 minutes (100–490). The average blood loss was 1491 ml (0–3500). The indication for PVCR was gross deformity and myelopathy which was due to congenital spinal deformities and one case of old tuberculosis. Clinical records and the radiographic parameters were reviewed. Results. Kyphosis of an average of 72 degrees was corrected to 28 degrees. The associated scoliosis was corrected from an average of 49.2 to 21.2 degrees. Ten patients improved neurologically to ASIA D and E. One patient deteriorated markedly, required revision with no initial improvement but reached ASIA E at 6 months after surgery. Four patients had associated syringomyelia. All were re-scanned at 1 year. The three with small syrinx's demonstrated no progression on MRI and the large syrinx resolved completely. In addition to the neurological deterioration, complications included 1 right lower lobe pneumonia. Conclusion. PVCR is an effective option to correct complex rigid kyphoscoliosis. In addition it allows excellent circumferential decompression of the cord and neurological recovery. When the congenital scoliosis is associated with syringomyelia with no other cause evident, it may allow resolution of the syrinx. Key words: Posterior vertebral column resection, severe spinal deformities, myelopathy, syringomyelia. NO DISCLOSURES
