Late infection is the most frequent complications after hemiarthroplasty.
Patients presenting with a fractured neck of femur are a fragile group with multiple co-morbidities who are at risk of post-operative complications. As many as 52% of patients are reported to suffer a
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. Methods. This observational cohort study enrolled consecutively admitted patients with a proximal femoral fracture, for which surgery was performed between 1 January 2018 and 11 January 2021 in two level II trauma teaching hospitals. Patients with medical indications to postpone surgery were excluded. A total of 1,803 patients were included, of whom 1,428 had surgery < 24 hours and 375 had surgery ≥ 24 hours after admission. Results. Prolonged total length of stay was found when surgery was performed ≥ 24 hours (median 6 days (interquartile range (IQR) 4 to 9) vs 7 days (IQR 5 to 10); p = 0.001) after admission. No differences in postoperative length of hospital stay nor in 30-day mortality rates were found. In subgroup analysis for time frames of 12 hours each, pressure sores and
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. Methods. The Premier Healthcare Database was queried to identify all patients who were diagnosed with metastatic bone disease from January 2015 to December 2020. The prevalence of all primary tumour subtypes was tabulated. Rates of long bone pathological fracture, 90-day mortality, and 360-day mortality following surgical treatment of pathological fracture were assessed for each primary tumour subtype. Patient characteristics and postoperative outcomes were analyzed based upon whether patients had impending fractures treated prophylactically versus treated completed fractures. Results. In total, 407,893 unique patients with metastatic bone disease were identified. Of the 14 primary tumours assessed, metastatic bone disease most frequently originated from lung (24.8%), prostatic (19.4%), breast (19.3%), gastrointestinal (9.4%), and urological (6.5%) malignancies. The top five malignant tumours resulting in long bone pathological fracture were renal (5.8%), myeloma (3.4%), female reproductive (3.2%), lung (2.8%), and breast (2.7%). Following treatment of pathological fractures of long bones, 90-day mortality rates were greatest for lung (12.1%), central nervous system (10.5%), lymphoma (10.4%), gastrointestinal (10.1%), and non-renal urinary (10.0%) malignancies. Finally, our study demonstrates improved 90-day and 360-day survival in patients treated for impending pathological fracture compared to completed fracture, as well as significantly lower rates of deep vein thrombosis, pulmonary embolism,
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. Methods. Patients aged ≥ 40 years, who underwent primary TSA between 2011 and 2017, were identified using International Classification of Diseases (ICD)-9 Clinical Modification and ICD-10 procedure codes for TSA in the New York Statewide Planning and Research Cooperative System database. Readmission, reoperation, and other complications were analyzed using multivariable Cox proportional hazards regression controlling for SDI, age, ethnicity, insurance status, and Charlson Comorbidity Index. Results. A total of 17,698 patients with a mean age of 69 years (SD 9.6), of whom 57.7% were female, underwent TSA during this time and 4,020 (22.7%) had at least one complication. A total of 8,113 patients (45.8%) had at least one comorbidity, and the median SDI in those who developed complications 12 months postoperatively was significantly greater than in those without a complication (33 vs 38; p < 0.001). Patients from areas with higher deprivation had increased one-, three-, and 12-month rates of readmission, dislocation, humeral fracture,
Aims. Deep surgical site infection (SSI) remains an unsolved problem after hip fracture. Debridement, antibiotic, and implant retention (DAIR) has become a mainstream treatment in elective periprosthetic joint infection; however, evidence for DAIR after infected hip hemiarthroplaty is limited. Methods. Patients who underwent a hemiarthroplasty between March 2007 and August 2018 were reviewed. Multivariable binary logistic regression was performed to identify and adjust for risk factors for SSI, and to identify factors predicting a successful DAIR at one year. Results. A total of 3,966 patients were identified. The overall rate of SSI was 1.7% (51 patients (1.3%) with deep SSI, and 18 (0.45%) with superficial SSI). In all, 50 patients underwent revision surgery for infection (43 with DAIR, and seven with excision arthroplasty). After adjustment for other variables, only concurrent
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. Methods. A retrospective cohort study was conducted in Japan using a nationwide multicentre database from April 2010 to March 2018, including 572,181 patients who had received hip fracture surgery. Propensity score matching was performed to compare patients who received additional weekend rehabilitation at the weekend in addition to rehabilitation on weekdays after the surgery (plus-weekends group), as well as those who did not receive additional rehabilitation at the weekend but did receive weekday rehabilitation (weekdays-only group). After the propensity score matching of 259,168 cases, in-hospital mortality as the primary outcome and systemic and surgical complications as the secondary outcomes were compared between the two groups. Results. The plus-weekends group was significantly associated with lower in-hospital mortality rates compared with the weekdays-only group (hazard ratio 0.86; 95% confidence interval 0.8 to 0.92; p < 0.001). Systemic complications such as acute coronary syndrome, heart failure, renal failure, and sepsis were significantly lower in the plus-weekends group, whereas
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
Aims. Patients with metabolic syndrome (MetS) are known to be at increased risk of postoperative complications, but it is unclear whether MetS is also associated with complications after total hip arthroplasty (THA) or total knee arthroplasty (TKA). Here, we perform a systematic review and meta-analysis linking MetS to postoperative complications in THA and TKA. Methods. The PubMed, OVID, and ScienceDirect databases were comprehensively searched and studies were selected and analyzed according to the guidelines of the Meta-analysis of Observational Studies in Epidemiology (MOOSE). We assessed the methodological quality of each study using the Newcastle-Ottawa Scale (NOS), and we evaluated the quality of evidence using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE). Data were extracted and meta-analyzed or qualitatively synthesized for several outcomes. Results. Ten cohort studies involving 1,352,685 patients were included. Qualitative analysis suggested that MetS was associated with a higher incidence of cardiovascular events, and meta-analysis showed that MetS increased the risk of all-cause complications (risk ratio (RR) 1.55, 95% confidence interval (CI) 1.28 to 1.89), surgical site infection (SSI; RR 2.99, 95% CI 1.30 to 6.90),
Objectives. To determine whether a delay to surgery (>36Hours) affects mortality rate, length of stay and post-operative complications following hip fracture surgery. Methods. Data collected by dedicated Audit staff using a proforma designed in accordance with the ‘Standardised Audit of Hip Fractures in Europe’ (SAHFE). A prospective Observational Study, all patients (n=7207) admitted and who underwent surgery during a 10-year period from May 1999 to May 2009 have been considered. Chi square tests and independent sample t tests were used for basic statistical analyses. Mortality data were analysed using Kaplan Meier survival analysis and cox regression analysis. p < 0.05 was considered significant. Results. The 30-day mortality was 9.5%. At 90 days, mortality was 18.9% and at 1 year it was 31.4%. In patients declared fit for surgery on admission (n=5665), 30-day mortality was 7.5% in those operated on without delay, rising to 10.3% at over 4 days delay (p=0.117). However, in those operated on after 5 days delay, 30-day mortality equalled 13.6% (p=0.009). Those declared fit for surgery on admission stayed a total 14.5 days if operated within 36 hours, rising to 16 days with over 36 hours delay (p< 0.001). An increase in the rate of
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. Methods. We obtained individual-based information on SES markers (cohabitation, education, income, and savings) on 103,901 THA patients from Danish health registries between 1 January 1995 and 31 December 2017. The primary outcome measure was any hospital-treated infection (i.e. all infections). The secondary outcomes were further specified to specific hospital-treated
One of the most important sequelae to ageing is osteoporosis and subsequently hip fractures. Hip fractures are associated with major morbidity, mortality and costs. Most patients require surgery to restore mobility. Provision of surgery and its complications is poorly understood in South Africa. Our aim was to collect and report current hip fracture care at four centres in South Africa, as well as reporting surgical and general patient outcomes. A three year retrospective cohort at four centres will be described, focussing on provision of surgical care, mortality, types of surgery and complications. We identified 562 patients who had surgical intervention for fragility fractures, 66% were females. Forty nine percent had open reduction and internal fixation, 28% had hemi-arthroplasty replacement whilst 23% had total hip replacements. Twenty percent of patients had operative intervention within 36 hours of presentation to the emergency department. Mortality was 9% at 30 days. The most common complications were lower respiratory
Aim. By gaining insight into the Quality of Life (QoL) status and occurrence of complications, critical facets in the care for patients with Fracture-Related Infection (FRI) can be mitigated and measures can be taken to improve their outcome. Therefore, the aims of this study were to 1) determine the QoL in FRI patients in comparison to non-FRI patients and 2) describe the occurrence of complications in both FRI and non-FRI patients. Method. An ambidirectional cohort study was conducted in a level-1 trauma centre between January 1st 2016 and November 1st 2021. All patients who underwent surgical stabilisation of a long bone fracture were eligible for inclusion. Patients with an Injury Severity Score (ISS) ≥16 or incomplete follow-up were excluded. QoL was assessed through the use of five-level EuroQol five-dimension (EQ-5D-5L) questionnaires twelve months post-injury. Results. A total of 134 patients were included, of whom 38 (28%) FRI patients and 96 (72%) non-FRI patients. In comparison to non-FRI patients, FRI patients scored significantly worse on the QoL assessment regarding the index value (p=0.012) and the domains mobility (p<0.001), usual activities (p=0.010) and pain/discomfort (p=0.009). During the median follow-up of 14.5 months (interquartile range (IQR) 9.5–26.5), 25 FRI patients developed a total of 49 distinctive complications besides FRI. The complications nonunion (18%, n=9/49), infection other than FRI (e.g. line

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
Prosthetic joint infections (PJI) are devastating complications. Our knowledge on hip fractureassociated hemiarthroplasty PJI (HHA-PJI) is limited compared to elective arthroplasty. The goal of this study was to describe the epidemiology, risk factors, management, and outcomes for HHA-PJI. A population-based (465,000) multicentre retrospective analysis of HHAs between 2006-2018 was conducted. PJI was defined by international consensus and treatment success as no return to theatre and survival to 90 days after the initial surgical management of the infection. Univariate, survival and competing risk regression analyses were performed. 1852 HHAs were identified (74% female; age:84±7yrs;90-day-mortality:16.7%). Forty-three (2.3%) patients developed PJI [77±10yrs; 56% female; 90-day-mortality: 20.9%, Hazard-Ratio 1.6 95%CI 1.1-2.3,p=0.023]. The incidence of HHA-PJI was 0.77/100,000/year and 193/100,000/year for HHA. The median time to PJI was 26 (IQR 20-97) days with 53% polymicrobial growth and 41% multi-drug resistant organisms (MDRO). Competing risk regression identified younger age [Sub-Hazard-Ratio(SHR) 0.86, 95%CI 0.8-0.92,p<0.001], chronic kidney disease (SHR 3.41 95%CI 1.36-8.56, p=0.01), body mass index>35 (SHR 6.81, 95%CI 2.25-20.65, p<0.001),
In patients admitted to hospital with a hip fracture, urinary issues are common. Despite guidelines that recommend avoiding foley catheter usage when possible, it remains a common part of perioperative care. To date, there is no prospective data on the safety and satisfaction associated with catheter use in such cohort. The aim of this study was to evaluate the satisfaction of patients when using a foley catheter while they await surgery for their fractured hip and the safety associated with catheter use. In our prospectively collected database, 587 patients were admitted to our tertiary care center over a 1 year period. Most patients (328) were catheterized within the first 24h of admission, primarily inserted in ED. Of these patients, 119 patients (61 catheterized and 58 noncatheterized) completed a questionnaire about their perioperative management with foley catheter usage administered on day 1 of admission. This was used to determine satisfaction of catheter use (if catheterized) and pain levels (associated with catheterized or associated with transferring/voiding if not catheterized). Adverse effects related with catheter use included
Introduction. Pre-operative urine screening is accepted practice during pre-operative assessment in elective orthopaedic practice. There is no evidence surrounding the benefits, effects or clinical outcomes of such a practice. Methods. A series of 558 patients undergoing elective admission were recruited during pre-assessment for surgery and were screened for UTIs according to a pre-existing trust protocol. All patients had their urine dipstick tested and positive samples were sent for culture and microscopy. Patients with a positive urine culture were treated prior to surgery and were admitted to the elective centre where strict infection control methods were implemented. The patients were followed up after their surgery and divided into three clinical groups: uneventful surgery; Suspected wound infection; Confirmed wound infection. Results. 85% of dipsticks tested were positive, while only 7% of the urine samples were culture positive. Over 36% of patients with a pre-operative
Purpose: Spinal epimorph is commonly used as part of multimodal analgesia for patients undergoing total joint arthroplasty. Patients who receive spinal epimorph are at risk for certain post- operative complications. The purpose of this study was to determine the incidence of complications in patients undergoing total joint arthroplasty with administration of spinal epimorph compared to patients undergoing the same procedure who did not receive spinal epimorph as part of their analgesia. Method: A retrospective chart review of 72 patients in which two age, sex and procedure matched groups were compared for differences in known spinal epimorph complications. One group received spinal epimorph as part of their analgesia while the comparative group did not receive spinal epimorph but rather continuous infusion of local analgesia. Data extraction involved foley and oxygen usage, documented nausea/vomiting and puritis, associated risk factors and complications such as prostate disease and
Bladder catheterisation following joint arthroplasty is not uncommon but delaying catheterisation in the postoperative period until the patient is symptomatic can produce an atonic bladder due to the distension. This can prolong catheterisation and increase the risk of
Introduction: There are several complications associated with spinal cord injury. The authors propose to evaluate the complications developed during hospitalization of tetraplegic patients treated in our institution. Materials and Methods: The clinical and imaging records of 20 tetraplegic patients operated between 1995 and 2007 were evaluated (14 men and 6 women; mean age 31.5 years; 16 submitted to surgery using anterior cervical approach, 4 using posterior approach; 8 did steroids protocol during 24h and 12 during 48h; 9 patients were operated less than 48h after trauma and 11 patients after). Results: Mean hospitalization time was 47.4 days (men 48.9 d, women 23.4 d; anterior approach 50.25 d, posterior approach 39 d; corticosteroids during 24h 34.3 d, 55.3 d in those who did 48h; time until surgery <

Introduction. Total knee arthroplasty (TKA) is an effective surgical intervention, which alleviates pain and improves function and health-related quality of life in patients with end-stage arthritis of the knee joint. With improvements in anesthesia, general health care, and surgical techniques, this procedure has become widely accepted for use in very elderly patients. However, many elderly patients tend to have compromised function and low reserve capabilities of organs and are therefore likely to develop various complications during the perioperative period. Thus, elderly patients often hesitate to undergo simultaneous bilateral TKA (SBTKA). Our purpose was to report the short-term results and clinical complications of octogenarians undergoing SBTKA. Materials and Methods. Between 2015 and 2016 all patients greater than 80years of age who underwent SBTKA by a single surgeon were retrospectively evaluated demographics, comorbidity, complications, and 30days mortality following SBTKA. Arthroplasty was performed sequentially under general anesthesia by one team led by primary surgeon. After the first knee, the patient's cardiopulmonary status was assessed by anesthesiology to determine whether or not to begin the second side. Cardiopulmonary decompensation, such as significant shifts in heart rate, oxygen saturation or blood pressure, was not showed. Then the second procedure was undertaken. Inclusion criteria of this study was underlying diseases were osteoarthritis. Exclusion criteria were (1) previous knee surgery; (2) underlying diseases were osteonecrosis, rheumatoid arthritis, fracture, and others. Fifty-seven patients with an average age of 82.7years were identified. The results of these procedures were retrospectively compared with those of patients greater than 80years of age of 89 patients unilateral TKA (UTKA) that had been performed by the same surgeon. Results. The study groups did not differ significantly with regard to age, gender, or body mass index. The mean age was 82.7years with a mean body mass index of 25.8 for the SBTKA group, compared with 84.0years with a mean body mass index of 24.9 for the UBTKA group. The length of hospital stay was longer in SBTKA groups. There was no serious complication. No deaths, no pulmonary embolisms and no nerve paralysis occurred within 30days in both groups. There was one wound problem in SBTKA group, compared 10 wound problem in UBTKA group; this difference was significant. Three deliriums occurred in SBTKA group, compared 13 deliriums in UBTKA group; this difference was significant. Minor complications included
The clinical guidelines for hip fracture management indicate that indwelling foley catheterization should be avoided when possible. Alternatives to indwelling catheters such as intermittent or condom catheters are recommended. Appropriate catheterization usage is important in hip fracture patients to avoid complications such as
Previous studies have indicated that prolonged surgical time may lead to higher rates of infection following total hip arthroplasty (THA). The purpose of this study was to evaluate the influence of surgical time on 30-day complications following THA and to determine if there was a time interval associated with worse outcomes. Patients ≥18 years who underwent THA between 2005 and 2016 were identified from the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database using procedural codes. Patients with surgical durations >240 minutes were excluded. Patient demographics, operation length, and 30-day major and minor complications were ascertained. Multivariable regression was used to determine if the rate of complications differed depending on length of operation, while adjusting for relevant covariables, and to identify independent predictors of operation length. Covariables of interest included age, sex, American Society of Anaesthesiologists (ASA) class, smoking status, functional status, comorbidities, anesthesia type, and Body Mass Index (BMI). A total of 131,361 THA patients (average age 65 ±12 years) were identified from the database. Of these, 2,177 (1.64%) experienced a major complication, and 3,504 (2.64%) experienced a minor complication within 30-days of the initial procedure. Average operation length was 91.9 minutes (range 20 – 240 minutes). Independent predictors of prolonged operation length included overweight/obese BMI, male sex, cancer, dependent functional status, epidural anaesthetic, lower pre-operative hematocrit, and ASA class II, III or IV vs. I Alternatively, older age, current smoking, and spinal anaesthetic were associated with shorter surgical durations. Unadjusted rates of both major and minor complications were significantly higher for patients whose operation lengths were ≥ 120 minutes (P>0.001). Specifically, patients whose operations lasted ≥ 120 minutes had higher rates of septic shock, sepsis, pulmonary embolism (PE), deep vein thrombosis (DVT),
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
INTRODUCTION. This study is to determine the response of CRP after TKR surgery, both unilateral and simultaneous bilateral TKR. According to the previously published literature from North America and Europe CRP value peaks on the 1. st. and 2. nd. post-operative day and then gradually comes down to normal by 6–8 weeks post-operatively. AIM. To determine the trend of CRP in Indian patients undergoing TKR, both unilateral and simultaneous bilateral TKR. To see whether it follows the trend in North American and European population and to determine whether there is a difference in the CPR pattern in unilateral versus simultaneous bilateral TKR patients. MATERIAL & METHODS. Twenty six patients were included in this study. 13 patients each had unilateral TKR and simultaneous bilateral TKR. All the patients were operated by a single surgeon and assistant. Patients who had Rheumatoid arthritis and post operative adverse events like
Introduction. Revision total knee arthroplasty (revision TKA) occurs for a wide variety of indications and along with revision total hip arthroplasty is billed for using Diagnosis-Related Groups (DRGs) 466, 467, and 468 in the United States. However, DRGs do not account for revision etiology, a potentially substantial driver of cost. This study investigates revision TKA costs and 30-day complications by indication, employing both local granular as well as national standardized databases. Methods. Hospitalization costs and complication rates for 1,422 aseptic revision TKAs performed at a high-volume center between 2009 and 2015 were retrospectively reviewed. Additionally, charges for 28,173 revision TKAs in the National Inpatient Sample (NIS) were converted to costs using the Healthcare Cost and Utilization Project cost-to-charge ratios. 30-day complication rates for 3,450 revision TKAs were obtained using the American College of Surgeons National Surgical Quality Improvement Project (ACS-NSQIP). Costs and complications were compared between revision TKAs performed for the indication of fracture, wear/loosening, and instability with use of simultaneous and pairwise comparisons and a multivariable model accounting for American Society of Anesthesiologists (ASA) score, age, and sex. Results. Local hospitalization costs for fracture (median, $30,643) were significantly higher than those for wear/loosening ($24,734; p < 0.001) or instability ($22,932; p < 0.001), with differences remaining significant even after adjusting for patient comorbidities (p < 0.001). Local fracture patients were admitted for an average of 1.9 days longer (mean length of stay [LOS]: 4.8 days; IQR: 3 – 6) than instability patients (mean LOS: 2.9; IQR: 2 – 3; p < 0.001) and 1.7 days longer than wear/loosening patients (mean LOS: 3.1, IQR: 2 – 3; p < 0.001) but had similar 30-day orthopedic-specific complication rates (10.8%) as compared to instability (11.2%; p > 0.999) and wear/loosening (15.9%; p = 0.333). Nationally, NIS costs for fracture (median, $31,207) were higher than those for other aseptic indications (wear/loosening: $21,747; instability: $16,456; p< 0.001). Combined medical and surgical complication rates for fracture (56.6% of patients with ≥1 complication) were significantly higher than those for wear/loosening (19.7%) and instability (15.5%) (p < 0.001), with 3.5 – 5.4 fold increased transfusion rates (45.7% fracture, 13.2% wear/loosening, 8.5% instability; p < 0.001) and 1.2 – 3.3 fold increased

Aim. In private healthcare facilities, the access to a specialized infectious disease (ID) advice is difficult. More, the lack of traceability is problematic and harmful for treatment and follow-up. We have tested an information technology (IT) application to improve medical transmission and evaluate an interdisciplinary ID activity. Methods. In November 2015, three ID physicians (IDP) created an interdisciplinary activity, visiting patients and giving phone advices among ten private healthcare facilities. They are members of the complex bone and joint infection unit of the community hospital where they are attached. Since September 2016, each advice was prospectively recorded on a protected online information system. These data are available for consultation and modification by the three IDP. It is the first descriptive analysis of this database. Results. From September 2016 to February 2017, 887 advices from 573 inpatients were collected. Median age was 69 years old and 56% of patients were male (n=320). Comorbidity was notified in 329 patients (57%): presence of a medical device (n=154), active neoplasia (n=76), mellitus diabetes (n=38) and renal failure (n=38) were the most common. Patients were hospitalized in a surgery unit in 49% of cases and of which 69% was the orthopaedic unit. By frequency, type of infection was prosthetic joint (n=111) and osteosynthesis device
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,
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),

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,
Aim. Surgical site infection (SSI) is associated with substantial morbidity, mortality and economic burden. Management of spinal SSI is becoming more challenging especially in instrumented cases, but is not well recognized as high risk procedure. The objective of this study was to determine the impact of procedure type comparing SSI risk with arthroplasties among all orthopaedic procedures. Method. Using prospectively collected data of consecutive samples in multi-center orthopedic SSI surveillance, we explored the differences in SSI rates within 30 days after surgery by procedure types. Patients who underwent surgery of single site between November 2013 and May 2016 were enrolled. SSI was our primary outcome.
Aim. Infection after vertebroplasty (VP) is a rare but serious complication. Previous literatures showed most pathogens for infection after VP were bacteria; tuberculosis (TB) induced infection after VP was extremely rare. In this study, we reported our treatment experiences of 18 cases with infectious spondylitis after VP, and compared the differences between developed pyogenic and TB spondylitis. Method. From January 2001 to December 2015, 5749 patients underwent VP at our department were reviewed retrospectively. The causative organisms were obtained from tissue culture of revision surgery. Parameters including type of surgery, the interval between VP and revision surgery, neurologic status, and visual analog scale of back pain were recorded. Laboratory data at the time of VP and revision surgery were collected. Risk factors including the Charlson comorbidity index (CCI), preoperative bacteremia,
Introduction. Few studies are published about total hip arthroplasties (THA) in Parkinson's disease as it is often considered as a contraindication for hip replacement. THA for fracture is reported as a high complication rate surgery. Regarding bone quality these cases are assimilated to elderly patients and cemented implants are generally preferred. However, due to the improved length and quality of life, we face more potential indications for joint replacement. The aim of this study is to report our experience of cementless dual mobility implants for primary THAs for osteoarthrosis and THA revisions focusing on the risks and benefits of surgery. Material and methods. 65 THA were performed in 59 patients (34 men, 25 women, mean age 73 years, 55–79). Mean latest follow-up was 8,3 years (4–14). Indications were 42 primary THA (osteoarthrosis) and 21 revisions (11 recurrent dislocation, 6 acetabular PE wear, 4 femoral loosening). Surgical approach was always antero-lateral. All patients were implanted with the same dual mobility cementless cup. The same cementless corail-type stem was used for primary THA cases. All the cemenless implants were hydroxyapatite coated. The disability caused by the disease was classified according to Hoehn and Yahr. (19 stage 1, 21 stage 2,16 stage 3). Results. 2 patients were lost for follow-up before 2 years. general complications were 3 pulmonary
PJI du to Enterobacter cloacae are rare and often severe. The aim of our study is to define the history of patients with such infections and their outcome. We conducted a retrospective monocentric study in an orthopedic unit where complex bone and joint infections are supported. From 2011 to 214 we selected patients with E. cloacae PJI based on data from the microbiology laboratory. In their files we collected information on their background, their medical and surgical history, antibiotics they received in the year before infection, the suspected portal of entry, the management and the outcome. Twelve patients were included, 7 male and 5 female. PJI was located to the hip in 8 cases, the knee in 3 cases and the ankle in one case. The average time between the placing of the first prosthesis and infection was 3 years. Eleven patients had one or more surgery for previous PJI. The average time elapsed since the last surgery was 30 days. Eleven patients had been treated with antibiotic combinations for at least 6 weeks, in the year before E cloacae infection. A portal of entry was identified only two times:
Deep joint infection is one of the most dreaded complications of total joint arthroplasty, and
Introduction. Previous studies have indicated that prolonged surgical time may lead to higher rates of infection following total hip arthroplasty (THA). The purpose of this study was to evaluate the influence of surgical time on 30-day complications following THA and to determine if there was a time interval associated with worse outcomes. Methods. Patients ≥18 years who underwent THA between 2005 and 2016 were identified from the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database using procedural codes. Patients with surgical durations >240 minutes were excluded. Patient demographics, operation length, and 30-day major and minor complications were ascertained. Multivariable regression was used to determine if the rate of complications differed depending on length of operation, while adjusting for relevant covariables, and to identify independent predictors of operation length. Covariables of interest included age, sex, American Society of Anaesthesiologists (ASA) class, smoking status, functional status, comorbidities, anesthesia type, and Body Mass Index (BMI). Results. A total of 132,043 THA patients (average age 65 ±12 years) were identified from the database. Of these, 2,177 (1.64%) experienced a major complication, and 3,504 (2.64%) experienced a minor complication within 30-days of the initial procedure. Average operation length was 92.0 minutes (range 20 – 240 minutes). Independent predictors of prolonged operation length included overweight/obese BMI, male sex, cancer, dependent functional status, epidural anaesthetic, and ASA class II, III or IV vs. I Alternatively, older age, current smoking, and spinal anaesthetic were associated with shorter surgical durations. Unadjusted rates of both major and minor complications were significantly higher for patients whose operation lengths were ≥ 120 minutes (P>0.001). Specifically, patients whose operations lasted ≥ 120 minutes had higher rates of septic shock, sepsis, pulmonary embolism (PE), deep vein thrombosis (DVT),
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,
Eleven total knee replacements were performed in eight patients with severe haemophilia A and the patients were followed up for two to eight years. All the patients had disabling haemophilic arthropathy of one or both knees, which had not responded to conservative treatment. Postoperative complications occurred in 10 knees, including nose bleeding, haemarthrosis, anaphylactic reactions,
Objectives. Although most joint surgeons have reached a consensus that preoperative risk assessment and appropriate medical intervention for elderly patients of primary total hip arthrplasty (PTHA) could significantly reduce postoperative complications and mortality, there is still lack of a detailed and comprehensive approach for risk stratifying and a systematic method for risk allaying. We aimed to explore the risk factors related to the aggravation of preoperative complications and the appearance of complications post-operation of primary total hip arthrplasty (PTHA) in elderly patients for hip fracture. Patients and methods. We retrospectively reviewed the demographic and clinical data of 156 patients who underwent PTHA for hip fracture from January 2014 to December 2016, of which there were 61 male (39.1%) and 95 female (60.9%) patients; 111 patients aged 60–79 years (71.2%) and 45 patients ≥ 80 years old (28.8%); 125 patients of femoral neck fracture (80.1%) and 31 patients of inter-trochanteric fracture (19.9%); 109 patients of spinal anesthesia (69.9%) and 48 patients of general anesthesia (30.1%); 85 patients undergoing surgery within 3 days (54.5%) and 71 patients operated ≥ 4 days (45.5%) since admission. We evaluated the correlations among gender, age, type of fracture, methods of anesthesia, time of operation since admission, the aggravation of preoperative complications and the appearance of postoperative complications post PTHA using the IBM SPSS Statistics (version 21) and the Exce1 2016. Results. The appearance of postoperative complications were statistically correlated with age, time of operation since admission, and type of anesthesia. The appearance of postoperative complication were significantly more in patients operated ≥ 4 days since admission (P < 0.05), and patients with general anesthesia (P < 0.05). Age ≥ 80 years old was not only statistically correlated with the aggravation of three kind of preoperative complications, hypertension, heart disease and respiratory tract infection (P < 0.05), also statistically correlated with the postoperative exacerbation of respiratory tract infection (P < 0.01), the appearance of anemia (P < 0.01), hypoalbuminemia (P < 0.01), water and electrolyte balance disorder (P < 0.05), and gastrointestinal reaction (P < 0.05). Age ≥ 80 years old was neither significantly correlated with postoperative aggravation of diabetes mellitus,
Pyogenic spondylodiscitis is an uncommon but clinically relevant infection that represents 3 to 5% of all cases or osteomyelitis. In Europe, it has an estimated incidence of 0.4 to 2.4/100.000 people/year. Mortality is less than 5%, increasing with a delay in diagnosis greater than 2 month. Patients with renal failure have greater predisposition to infections, consequence of the chronic uremic state. Infection rates in Polytetrafluoroethylene (PTFE) hemodialysis grafts in end-stage renal disease (ESRD) range from 3 to 35%. We present a rare case of concurrent spondylodiscitis and PTFE graft infection in a patient with ESRD and recurrent
In this study we aimed to identify infection rates in arhroplasty patients which were operated bilaterally with single anesthesia and to discuss the reasons of infections in these patients. We evaluated 163 knees of 82 patients (Follow up: 12 to 60 months). Mean age was 66.8. Right knees were operated first followed by left knees. 16 of the patients had diabetes mellitus, 4 of them had rheumatoid arthritis, and 1 of them had systemic lupus erithmatosus. All patients were evaluated according to operation time, wound healing, laboratory findings, clinical presentation and X rays. We had 7 infections (6 deep, 1 superficial infection). When we evaluate operation times, no statistically significant difference was obtained between the infected knees and non infected knees (p=0,275). Two of the infected knees had urinary track infection and dental abscess after the opertaion. Five of seven infected knees were left sided. Six of the infected knees were treated with debridement irrigation and antibiotics successfully. But one had two staged revision. Bilaterally operated knee arthroplasty increases operation time significantly. This increase of operation time decreases the sterility of surgical field, and may increase infection rates. The increased infection rates in left sided knees may explain this. Postoperative dental and
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
