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. 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. 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
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. 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
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

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:
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),
Deep joint infection is one of the most dreaded complications of total joint arthroplasty, and
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
Background: A common problem following total joint arthroplasty is urinary retention, which often necessitates catheterisation in the postoperative period. Most of these catheterisations are done as an emergency in the ward where the sterility is less than optimal. Methods : A retrospective study of the incidence of emergency urinary catheterisation in 300 male patients who underwent total joint Arthroplasty under spinal anaesthesia over an eighteen-month period is presented. The patients were divided into three groups according to their age Group 1 (50 to 65 yrs), Group 2 (65 to 70 yrs) and Group 3 (70 + yrs). Results: The incidence of catheterisation for acute urinary retention in Group 1 was 20%, Group 2 – 65% and Group 3 –69%. Discussion: Urinary stasis predisposes to infection. The direct relationship between urinary catheterisation and infections in total joint Arthroplasty is already well documented. The potential for infection is compounded if the procedure is carried out in the unsterile ward environment. This study shows that the incidence of emergency catheterisation in patients aged 65 or above was high (average 67%) . Conclusion: We conclude that these patients in groups 2 and 3 should be catheterised electively in the optimal sterile environment of the operating theatre. Catheterization should be performed after the patient has had the anaesthetic and the prophylactic intravenous antibiotic has been administered. The potential occurrence of joint and
Purpose: As the prevalence of diabetes mellitus (DM) in people over 60 years of age is expected to increase, the number of diabetic patients who undergo total hip and knee arthroplasty should increase concordantly. In general, patients with DM have significantly increased risk for adverse events following arthroplasty. The goal of this study was to determine whether the quality of glycemic control affected the incidence of perioperative complications in the hospital following joint replacement. Method: From 1988 to 2003, the Nationwide Inpatient Survey (NIS) recognized 65,769 patients who had DM and underwent joint replacement surgery. In this retrospective study, bivariate and multivariate analyses compared patients with uncontrolled (n=2,872) and not uncontrolled (n=62,897) DM regarding common surgical and systemic complications, mortality, and hospital course alterations. Glycemic control was determined by physicians’ assessments based upon the American Diabetes Association guidelines using a combination of patients’ self-monitoring of blood-glucose testing, the hemoglobin A1C, and related complications. Results: Patients with uncontrolled DM routinely had an increased length of stay and increased inflation-adjusted costs after surgery (p<
0.001). Uncontrolled patients also had significant increases in the incidence of stroke, pneumonia,
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),
A clinical retrospective study was conducted. Results of isolated decompression for degenerative lumbar stenosis was compared with the outcome in patients who underwent decompression-stabilisation. From January 1992 to December 2002, 127 patients (average age 65.5) with lumbar degenerative stenosis surgically treated were studied. In all patients the Roy-Camille technique was used for decompression; in 41 patients decompression and posterior stabilisation procedures were carried out. Average follow-up was 6 years (range 2–11 years). The outcomes, evaluated according to Lassale classification, were satisfactory in 81% of the decompressed group while improved to 88% in the stabilised–decompressed group. Three patients of the first group required stabilisation for intractable low back pain (one patient) and lumboradicular symptoms (two patients), while problems related to the device (one hardware failure) and two instances of adjacent segmental instability were seen in the second group. Decompression alone is associated with an increased rate of residual low back pain (one patient in this cohort required fusion). The decompression–stabilisation procedure reduces the incidence of low back pain but is associated with other complications such as significant blood loss, possible wound
Introduction: Compromised by pre-existing medical co-morbidities, weakened by the second hit of surgery, elderly patients with hip fractures are amongst the most challenging cases to manage appropriately in the acute hospital setting. Aim: To document the frequency and outcome of post operative medical complications in elderly patients following surgery for hip and proximal femoral fractures. Methods: Retrospective analysis of acute admissions to a University teaching hospital with hip and pertrochanteric fractures over an 18 month period. Medical records and radiographs were reviewed for details relating to location of fracture, in-patient morbidity, mortality and length of stay. In-patient fracture referrals and patients under 65 years of age were excluded. Results: From a total of 438 fracture fixation procedures or prosthetic replacements, 368 patients were eligible for analysis. The mean age of patients was 83.6 years. The mean length of stay was 14.2 days. 142 patients experienced significant postoperative morbidity consisting of 24 myocardial infarctions, 46 respiratory
Background. Vertebral body compression fractures (VCFs) impair quality of life (QOL) and increase patient morbidity and mortality. The international, multicentre, randomised, controlled Fracture Reduction Evaluation (FREE) trial was initiated to compare effectiveness and safety of Balloon kyphoplasty (BKP) to non-surgical management (NSM) for the treatment of acute painful VCFs. We describe the primary endpoint of the ongoing 2-year study. Methods. Patients with 1-3 non-traumatic VCFs (< 3 months old) were randomised to either BKP or NSM. The primary endpoint was the change in QOL as measured by the SF-36 Health Survey Physical Component Summary (PCS) at one month, and device/procedure-related safety. Secondary endpoints included SF-36 subscales, the EQ-5D, self-reported back pain and function using the Roland Morris Disability Questionnaire (RMDQ). All patients were given osteoporosis medical therapy. Results. Among the BKP (N=149) and NSM (N=151) cohorts, mean patient age was 73 years and 77% were female. Most patients had VCFs due to primary osteoporosis; 8 patients due to corticosteroid-induced osteoporosis, and 4 had cancer-related fractures. Thirty-nine BKP (26%) and 36 NSM (24%) patients had >1 VCF treated. At one month follow-up, the mean improvement in the PCS was in favour of BKP over NSM (p<0.0001). All physical component SF-36 subscales and the total EQ-5D score were significantly improved for BKP compared to NSM. Mean improvements in back pain at 7 days and 1 month were significantly greater for BKP compared to NSM (p<0.0001 at both time points). The improvement in RMDQ for BKP over NSM was also significant (p<0.0001). There was one soft tissue haematoma and
Introduction: Infection remains the single most important complication in elective joint replacement. 1.1% of patients suffer early deep infection and 10–17% of patients superficial infection [. 1. ]. Antibiotic prophylaxis has been used extensively in elective orthopaedic practice, approximately halving the post-operative infection rate [. 2. ]. Cefuroxime is almost universally used in the UK. However there is an increased incidence of multiple drug resistant bacteria within the environment in addition cephalosporin use and resistance is widespread [. 3. ]. Many patients are treated pre-operatively for
Acute urinary retention (AUR) is a common complication following arthroplasty of the major joints and may lead to a delayed discharge with financial considerations not to mention the risks of sepsis – in the urinary tract and also rarely but very significantly in the joint itself. Our aim was to study the various factors associated with risk of AUR following arthroplasty. We conducted a retrospective review of all available casenotes of patients undergoing total hip (THR) and knee arthroplasty (TKR) in a consecutive three year period. Variables noted included rate of AUR, catheterisation,
Introduction: A hip replacement is an usually procedure in patients with chronic renal failure (CRF) affected of osteoarthritis, avascular necrosis of the femoral head or femoral neck fracture. The infection of the prosthesis is the most severe and important complication related to hip arthroplasty (HA). Patients with CRF have a immunosupression status, that increases the infection risk. The aim of the study was to evaluate the results of HA in patients on renal replacement therapy (RRT) through haemodialysis (HD) or renal transplantation (RT) . Material and methods: Between 1990 and 2002, 23 HA have been performed in 18 patients on RRT (9 patients on HD and 9 RT). There were 9 women and 9 men, with an average age of 56 years old (range 30–83). In 5 patients the procedure was bilateral. The average time on RRT was 13.1 years (range 4–28). Preoperative diagnostic was: avascular necrosis of the femoral head (15 hips), femoral neck fracture (6 hips) and hip dysplasia (2 hips). Results: The average follow-up was 59 months (range 3–140). All patients received antibiotic prophylaxis. Bleeding was the most frequent complication (74%, n=17). Infectious complications occurred in 33% of HA (n=6) in the early postoperative period and in 9% of HA (n=2) during the long-term follow-up. Early
The current work compares, in the patients with acute spinal cord injuries (SCI), the rate of early complications in those who were operated ‘out of hours’ to the patients who had their surgical interventions performed on the elective trauma list. In a two-year study, all the complications occurring within the first month of surgery were recorded. Patients who had their operative procedure between 22.00 pm and 8.00 am comprised the ‘out of hours’ group, while the other group included patients operated on daytime spinal trauma lists. Each group had 22 patients. The demographics, injury patterns, time relapse to admission and theatre, the surgical procedure, its duration, the postoperative results and early complications were retrospectively analysed and compared for the two groups. There were 38 males. 20 patients had complete SCI and 26 had thoracic spine involvement. Road traffic accident was the cause of injury in 26 patients. Two patients received steroids following the injury. The average admission time was 3 days. Surgery occurred on an average within 48 h (range 1–20 days). The mean theatre time was 2.8 h for the emergency group and 3.4 h for the elective cases. Early postoperative complications were chest infections (5),
Introduction and Objectives: The medical literature describes asymptomatic
A prospective study of 142 consecutive patients admitted with fracture of the neck of femur was performed. 42 patients were operated within 24 hours of time of fracture (group 1), 46 within 24 to 48 hours (group 2) and 47 more than 48 hours later (group 3). Three patients were treated conservatively and in four patients the exact time of fracture was not known. The reason for delay of the operation was lack of theatre space in the majority of cases (64 patients). Medical problems accounted for delay in only 10 patients.Seven patients out of 42 in group 1 died within four month (16.7%), compared to 11 of 46 in group 2 (23.9%), and 6 out of 47 in group 3 (12.8%). This difference was not statistically significant. There was no significant difference in requirement for pre- and postoperative blood transfusion between the three groups. No patient operated within 24 hours developed pressure sores. Three patients in group 2, and six patients in group 3 developed pressure sores. Chest infections occurred in three patients in group 2, and in three patients in group 3. None of the patients operated on within 24 hours developed a chest infection, wound
Serological tests including erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) are frequently used in the preoperative workup to screen for periprosthetic infection (PPI) in total hip arthroplasty (THA). The cut-off points reported in the literature are arbitrarily chosen by investigators. Similarly, the values used in laboratories to distinguish elevated results vary from one institute to another. Therefore, we intended to define the appropriate cut-off points of ESR and CRP that can be used to differentiate infection from aseptic failure of THA. A review of our joint registry database revealed that 515 THA revisions (131 infected cases) were performed during 2000–2005. Intraoperative samples for culture were taken in all cases. The criteria used for diagnosis of infection were a positive intraoperative culture on solid media, presence of an abscess or sinus tract that communicated with the joint, positive preoperative aspiration culture, and/or elevated fluid cell count and neutrophil differential of the aspirated fluid. Non-infected patients with confounding factors that can elevate ESR and CRP including collagen vascular disease, inflammatory arthropathy, malignancy, and
Purpose of the study: Percutaneous compressive plating (PCCP) enables minimally invasive surgery using closed focus technique. We report a prospective consecutive series of 67 fractures (December 2003 – February 2005) followed to bone healing. Material and methods: Mean patient age was 83 years (range 37–95) with 83% females in a frail population (ASA 3, 4). Two-thirds of the patients had unstable fractures (AO classification) which were reduced on an orthopedic table under fluoroscope. Two minimal incisions were used to insert the material without opening the fracture and without postoperative drainage. Blood loss was noted. Verticalization and weight bearing were encouraged early depending on the patient’s status but were never limited for mechanical reasons. Patients were reviewed at 2, 4 and 6 months. Results: Anatomic reduction was achieved in 84% of hips, with screw position considered excellent for 45, good for 14, and poor for 6. There were no intraoperative complications. The material was left in place. The hemoglobin level fell 2.2 g on average. Mean operative time was 35 minutes and the duration of radiation exposure 60 seconds. Mean hospital stay was 13 days. General complications were:
Obesity is increasing among patients requesting total hip replacement. Obesity is often considered though, a relative contraindication to arthroplasty surgery due to difficult access, greater blood loss, oozy wounds, poor mobilisation and delayed discharge. We have attempted to demonstrate the evidence for this. Patients were evaluated preoperatively with regards to their height and weight to allow a body mass index (BMI) to be calculated. The length of inpatient stay was then monitored and early postoperative complications recorded. This data was used to assess if obesity or age could be used to predict a prolonged hospital stay caused by poor rehabilitation and early post operative complications. The results of 70 consecutive patients between 1999–2001 are reported. The average age was 69.3 with a range of 46.5–85.4 years. The sex distribution was approximately 2:1 female to male (N=48:22 respectively). Two patients were identified as being under their recommended weight, 24 as healthy, 26 as over weight and 18 as obese.
It is important to optimise not only the operative treatment, but also the general medical condition of hip fracture patients to achieve the best rehabilitation result. Patients with a hip fracture are old and often suffer from concomitant diseases. They are prone to be affected by complications such as pneumonia,
Diving injuries are the cause of devastating trauma, primarily affecting the cervical spine. The younger male population is more often involved in such injuries. This study describes our experience on diving injuries treatment and offers a long follow-up. During a 31-year period (1970–2001) 20 patients, 19 male and one female have been admitted with cervical spine trauma following a diving injury. All admissions have been made between May and September. One patient was lost to follow-up. The mean age of the patients was 23 years (16–47). The lower cervical spine was involved in 13 patients; four patients had lesions in the middle and upper cervical spine, while one patient had combined lesions. The most commonly fractured vertebrae were C5 and C6. Fracture-dislocation was evident in 10 patients, while a teardrop fracture was diagnosed in six patients. Six patients were classified, as ASIA A upon admission and bladder control was absent in 12. Only four patients were treated surgically, two with iliac bone grafting alone, one with posterior plating and one with an anterior plate plus graft. The other patients with initial neurological deficit were treated conservatively, because of their rapid neurological improvement, their lesion being regarded as stable. Fourteen patients were treated conservatively with steroids and Crutchfield skull traction or halo vest, followed by the application of a Minerva or Philadelphia orthosis. The mean follow-up was 11 years (6 mo to 23.8 years). Four patients in the ASIA A category died in the first month of their hospitalization (two of cardiac arrest, one from pulmonary embolism and one from respiratory infection) and two remained unchanged. Six patients with ASIA B and C improved neurologically and one remained unchanged. Nine patients had developed
Objective: To assess the safety and outcome of laminectomy in patients with spinal stenosis operated at the age of 65 years or older. The relation between the duration of the symptoms and results was investigated. Study Design: A retrospective chart analysis with up to 10 years follow-up. Setting: The Spinal Care Unit, Meir Medical Center, Kfar Saba, Israel. Material and Methods: The medical records of all patients who had laminectomy for spinal stenosis at the age of 65 or more in a 10 years period were reviewed. Assessment of pain, ability to perform the basic activities of daily living, transferring dressing and basing before and after the operation was done by a telephone interview. Patient’s self-estimation of the final result of the surgery was also recorded. Results: Two hundred eight-three patients were eligible to participate in the study. They were allocated into 3 groups according to the duration of symptoms before surgery. Group A with symptoms lasting up to 24 months, B with 25–48 months and C with symptoms lasting for more than 48 months. The average age at the time of the operation was 68.9, 72.6 and 71.3 years, respectively. Forty-eight patients died and 18 refused or were not able to participate in the study. The average time of follow-up was 43.3 months, 42.2 in group A, 47.4 in B and 42.8 in C. No significant differences were noticed in the demographic, anesthetic and surgical parameters among the 3 groups. There were no mortality cases in the immediate postoperative period. The overall complication rate was 43.5%, nearly identical in all 3 groups. Two patients had cerebrovascular accident and 5 had myocardial ischemia but no one turned into infarction. Mild complications included 11 urinary retention, 24
This study examines patient characteristics, indications for conversion, surgical and anaesthetic technique, peri-operative management and complications of surgery in this small and challenging group of patients. In the six years from 1994 to 1999, 33 conversion arthroplasties were performed for failed femoral hemiarthroplasty. The average age at conversion surgery was 75.5 years (range 65–90). The female to male ratio was 6:1. Primary hemiarthroplasties comprised 24 Austin-Moore, 6 Thompson &
3 Bipolar prostheses. The average interval from primary to conversion surgery was 50 months (6 months to 17 years). The average age at primary surgery was 71.2 years (62–88) – AMP:71.4 years, Thompson’s: 74.2 years, Bipolar: 63.5 years. All hemiarthroplasties were performed for fractured femoral necks. 62% of patients came from the Eastern Health Board area, while 38% were tertiary are referrals from other Health Boards. The average length of stay was 17.5 days (3–24). Indications for conversion included gross loosening/acetabular erosion in 9 cases, suspected infection in 4 cases and abscess/septicaemia in 1 case. All but 3 patients had significant pain (night pain etc.) and/or severely impaired mobility. We also looked at anaesthetic and analgesic practice, surgical technique and prostheses used. Post-operatively, mean total blood loss was 1430 ml (420–2280) with an average of 1.4 units of blood transfused (0–5). Intraoperative complications included acetabular &
femoral perforation, periprosthetic fracture and cement reactions. Complications post-op (in hospital) included cardiac arrhythmia’s, cerebrovascular accidents, pulmonary embolus, myocardial infarct, respiratory &
Introduction and Aims: The aims of this study were to assess the clinical and functional outcomes following the treatment of a lumbar Chance fracture and to analyse the spectrum of associated abdominal injuries as seen in the Seat Belt Syndrome. Method: All patients diagnosed with L1 to L4 Chance fractures at the British Columbia Children’s Hospital were included in this study. Patient data, injuries, treatment and complications were collected from hospital charts. A review of all available spinal radiology including pre-treatment, post-treatment and follow-up x-rays, CTs and MRIs was done to measure pre-treatment, post-treatment and follow-up kyphosis angles, as well as to help classify the Chance fracture. Patients were seen in follow-up to assess for range of motion, tenderness and neurological status. Furthermore, a functional outcome questionnaire by the American Academy of Orthopaedic Surgeons Pediatric Instruments was completed by the patients. Results: Between December 1984 and February 2001, 27 patients aged three to 17 were treated for lumbar Chance fractures. The mean age at injury was 11.1 years. There were 18 females and nine males. All injuries occurred as a result of a motor vehicle accident. Nineteen were rear-seat passengers and eight were front-seat passengers. Of the 27 patients, 19 were treated surgically. Of these 19, nine were treated with either pedicle screws or laminar hooks and rods, four with intersegmental spinous process (ISP) wires alone, two with sublaminar wires and four with a combination of screws/hooks, rods and ISP wires. One patient had a post-operative
1. Ectopic ossification is commonest in, but not confined to, traumatic paraplegia. It occurs also in many other neurological disorders which have in common a gross disturbance of spinal cord reflex activity. It is a true ossification and must be distinguished from calcification. 2. The neurological lesion may lie anywhere from the cerebral cortex to the mixed peripheral nerve. It may involve motor tracts, sensory tracts or a mixture of both. 3. The ossification is localised and self-limiting. It occurs mainly in the lower limbs and is restricted to certain muscles or muscle groups, the nerve supply of which is always below the level of the central neurological lesion. 4. The blood chemistry is usually normal. 5. A true arthropathy is rare except as part of a secondary suppurative arthritis. 6. The resemblance to myositis ossificans progressiva or to ossifying haematoma is only superficial, although the pathological process at cellular level may be the same. 7. The period of onset after paraplegia is variable. The earliest recorded example is in one of our own cases in which ossification occurred nineteen days after injury. Other patients have developed ossification after several years. 8. The condition is commonest in acquired nervous disease rather than in congenital disorders, and so far as we know it has not been described in the myopathies. The presence of muscular spasticity or flaccidity is relevant only in that it indicates a disturbance of reflex activity. 9. Soft-tissue ulceration appears to be frequently associated with ectopic ossification. The type of new bone formation associated with large chronic ulcers is not to be compared with the new bone formation in the muscles of a paraplegic patient in otherwise good general condition. 10. The occurrence of
Background: Distinguishing septic arthritis from transient synovitis of the hip in children can be both crucial and challenging. In 1999, Kocher et al suggested four clinical predictors, fever >
38.5°C, inability to weight bear, WBC count >
12.0x109/L, and ESR>
40mm/hr; that, when combined were highly predictive of septic arthritis in children (99.6%). This figure was challenged by Luhmann et al, stating that the clinical prediction did not exceed 59%. In 2006, Caird et al recommended adding CRP of >
20mg/L as a fifth predictor. Aims: To assess the value and accuracy of clinical prediction algorithms in distinguishing septic arthritis from transient synovitis of the hip in children in our hospital. Methods: A retrospective review of all children admitted to our institution with painful hips was carried out over a period of four years (Feb 2003 to Mar 2007). One-hundred and twenty-two admissions (115 patients, 7 re-admissions) were reviewed. Results: 79 patients (64.8%) were males. The mean age was 6 years (9 months to 15 years). 86 patients (70.5%) were diagnosed with transient synovitis. All the 7 re-admissions were from this group. Only one of the re-admissions was diagnosed with confirmed septic arthritis. 4 patients (3.3%) were diagnosed with definite septic arthritis with positive cultures from the hip, and 1 (0.8%) with probable septic arthritis (negative culture). The presence of the clinical predictors was compared between the transient synovitis and septic arthritis groups, using Fisher’s exact test. Only the raised temperature and CRP were found to be significantly different (p<
0.05). Only two children (40%) with confirmed septic arthritis had four or more predictors (one had all five, and the other was able to partially weight bear). The third child had a raised temperature and CRP, and the fourth had a raised temperature only. The fifth patient (20%) was diagnosed with probable septic arthritis. His cultures were negative, but he was already on intravenous antibiotics. This patient did not have any of the predictors on admission (temperature was 38.3°C, CRP 10.7). However, he spiked a temperature of 40°C 24 hours post admission despite being on antibiotics, and his CRP increased to 34.5mg/L. In the transient synovitis group, two patients (2.2%) had positive five predictors, but were proven to have transient synovitis secondary to a
In the UK, surveillance for surgical site infection is mandatory for orthopaedic surgery. NHS trusts must participate for at least one surveillance period (3 months) every year in at least one of four categories:- hip replacement, knee replacement, hip hemiarthroplasty or open reduction of long bone fractures. Surgical site infections (SSIs) are defined as infections related to a surgical procedure that affects the surgical wound or deeper tissues handled during the procedure. Since mandatory surveillance began in 2004, rates of SSIs have markedly decreased. This is postulated to be secondary to increased early detection. Shorter postoperative stays and underestimation are also likely to be influential factors. We reviewed 150 consecutive lower limb arthroplasties performed at a district general hospital from July to September 2007. All inpatient data were collected as part of the Health Protection Agencies mandatory surveillance. We reviewed this data and notes for recorded evidence of infections or complications for minimum of one year after surgery. We reviewed computer records for recorded microbiological evidence of infection preoperatively and postoperatively. The operations performed during the surveillance period were:- 60 primary total knee replacements (TKRs), 37 primary hip replacements (THRs), 25 hip resurfacings, 15 unicondylar knee replacements, 3 patello-femoral joint replacements, 6 revision TKRs and 4 revision THRs. No SSI’s were detected during the mandatory surveillance period (i.e the inpatient stay, mean 5.61 days, Range 2–44 days). Two SSI’s (1.33%) were detected in our follow up period. Both were superficial wound infections. The first, a 53 year old hip resurfacing patient who was discharged 3 days postoperatively and developed Staphyloccocal infection 5 days later. The other was a 76 year old who underwent THR surgery, was discharged at day 6 and presented on day 12 with Pseudomonas wound infection. Both cases were initially diagnosed and treated successfully with oral antibiotic by GPs. One 61 year old patient who underwent hip resurfacing presented at day 62 with pain. X-rays showed loosening. Deep infection was suspected but hip aspirate, and inflammatory markers were negative. He is being monitored in the outpatient department. Our analysis also revealed that 3 patients had
Introduction Bilateral total knee replacement under one anaesthetic is a common procedure. Claimed benefits include: shorter hospital stays, fewer complications of some kinds, lower over all cost and more efficient use of staff time. In general the literature supports these concepts though some writers caution against the procedure. Most studies come from large university hospitals but most joint replacements are done in smaller hospitals. At Calvary Hospital we instituted a quality assessment review of our experience to determine patient safety and cost savings. Methods A medical records review between 1997 and 2001 showed 63 patients had bilateral total knee replacement (126 knees). We further identified 38 patients who had both knees replaced at separate admissions within one year (76 knees), these were the staged knee replacements. We selected a matched subset of the patients who had only one joint replaced in this period (125 knees). A review was carried out over a wide variety of parameters on a relation database. Results The incidence of infection, unplanned return to theatre and DVT was too low for this study to have statistical power and little difference was noted. Amongst the more common post-operative respiratory, cardiovascular and gastrointestinal complications no significant difference was noted per hospital admission. Post-operative confusion was not more common in bilateral replacements and we felt that fat embolism syndrome was not increased. Neither, type of anaesthesia, previous medical history nor post-operative care predicted for confusion but we did note a strikingly increased incidence in patients of low BMI. Contrary to common views obese patients did not have more complications or longer hospital stays. Mobilisation in heavy patients is not prolonged provided they have good upper limb strength. Blood transfusion is more likely in bilateral cases but our review has allowed us to formulate a nomogram based on weight and pre-operative haemoglobin to improve blood management. High admission rates to ICU were noted but mostly for precautionary reasons, the unplanned admission rate was not greater. Pre-operative
Background: To determine patients clinical and haematological characteristics that could affect the use of blood and infection incidence with hip fractures (HF) treated with a dynamic hip screw (DHS). Patients and Methods: A retrospective study of all the HF patients during 5 years (January1995- December1999) who were treated with a dynamic hip screw (DHS ïf’, Synthes-Stratec, Oberdof, Switzerland) at one unique university hospital. No patient was excluded. Age, gender, elapsed time, anaesthesia risk (ASA clasification), type of HF (internationalAO classification), transfusion procedure and the total used; haemoglobin (Hb) at days 0 (incoming to urgency service) and first postoperative (POD ï€1) were examined. We also analyzed the infection incidence (CDC criteria), place and severity. The statistical univariate analysis included Student’s t-test for numeric variables and Pearson’s chi-squared test for string variables. There was considered to be a statistically significant difference (SSD) when p<
0.05. A multivariate stepwise logistic regression model was used. Results: Three hundred and one patients with HF were studied. 125 A1 and 176 A2, according to the AO classification. Male/female ratio: 76/225 (25.2%/74.8%); age 78.97 years old (range: 23–104); ASA: I 53 (17.6%); II 97 (32.2%); III 138 (45.8%) and IV 13 (4.3%). Hb Values on the day of admission: 128.7 g/L (range: 81.7–176.7) and POD ï€1: 101 g/L (range: 54.7–150.7). 186 (61.8%) patients were transfused with an average 1.42 red cell concentrate (range: 0–6). 89 (29.6%) had an infection diagnosis: 79 (26.2%)
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. We performed a systematic literature search in MEDLINE, Embase, and Web of Science. The search string included multiple synonyms of the following keywords: "revision TKA", "outcome" and "prognostic factor". We searched for studies assessing the association between at least one prognostic factor and at least one outcome measure after rTKA surgery. Data on sample size, study design, prognostic factors, outcomes, and the direction of the association was extracted and included in an evidence map.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. A comprehensive literature search was conducted to identify eligible studies reporting postoperative outcomes in IBD patients undergoing joint arthroplasty. The primary outcomes included postoperative complications, while the secondary outcomes included unplanned readmission, length of stay (LOS), joint reoperation/implant revision, and cost of care. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using a random-effects model when heterogeneity was substantial.Aims

The aim of this study was to assess the clinical and radiological results of patients who were revised using a custom-made triflange acetabular component (CTAC) for component loosening and pelvic discontinuity (PD) after previous total hip arthroplasty (THA). Data were extracted from a single centre prospective database of patients with PD who were treated with a CTAC. Patients were included if they had a follow-up of two years. The Hip Disability and Osteoarthritis Outcome Score (HOOS), modified Oxford Hip Score (mOHS), EurQol EuroQoL five-dimension three-level (EQ-5D-3L) utility, and Numeric Rating Scale (NRS), including visual analogue score (VAS) for pain, were gathered at baseline, and at one- and two-year follow-up. Reasons for revision, and radiological and clinical complications were registered. Trends over time are described and tested for significance and clinical relevance.Aims

Nonagenarians (aged 90 to 99 years) have experienced the fastest percent decile population growth in the USA recently, with a consequent increase in the prevalence of nonagenarians living with joint arthroplasties. As such, the number of revision total hip arthroplasties (THAs) and total knee arthroplasties (TKAs) in nonagenarians is expected to increase. We aimed to determine the mortality rate, implant survivorship, and complications of nonagenarians undergoing aseptic revision THAs and revision TKAs. Our institutional total joint registry was used to identify 96 nonagenarians who underwent 97 aseptic revisions (78 hips and 19 knees) between 1997 and 2018. The most common indications were aseptic loosening and periprosthetic fracture for both revision THAs and revision TKAs. Mean age at revision was 92 years (90 to 98), mean BMI was 27 kg/m2 (16 to 47), and 67% (n = 65) were female. Mean time between primary and revision was 18 years (SD 9). Kaplan-Meier survival was used for patient mortality, and compared to age- and sex-matched control populations. Reoperation risk was assessed using cumulative incidence with death as a competing risk. Mean follow-up was five years.Aims

Hip fractures are a major cause of morbidity and mortality, and malnutrition is a crucial determinant of these outcomes. This meta-analysis aims to determine whether oral nutritional supplementation (ONS) improves postoperative outcomes in older patients with a hip fracture. A systematic literature search was conducted in August 2022. ONS was defined as high protein-based diet strategies containing (or not containing) carbohydrates, fat, vitamins, and minerals. Randomized trials documenting ONS in older patients with hip fracture (aged ≥ 50 years) were included. Two reviewers evaluated study eligibility, conducted data extraction, and assessed study quality.Aims

The escalating demand for medical resources to address spinal diseases as society ages is an issue that requires careful evaluation. However, few studies have examined trends in spinal surgery, especially unscheduled hospitalizations or surgeries performed after hours, through large databases. Our study aimed to determine national trends in the number of spine surgeries in Japan. We also aimed to identify trends in after-hours surgeries and unscheduled hospitalizations and their impact on complications and costs. We retrospectively investigated data extracted from the Diagnosis Procedure Combination database, a representative inpatient database in Japan. The data from April 2010 to March 2020 were used for this study. We included all patients who had undergone any combination of laminectomy, laminoplasty, discectomy, and/or spinal arthrodesis.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. This nationwide retrospective cohort study used data from the Diagnosis Procedure Combination database. We included patients aged ≥ 18 years who underwent surgery for hip fractures and received acetaminophen combined with NSAIDs (combination group), NSAIDs alone (NSAIDs group), or acetaminophen alone (acetaminophen group) preoperatively, between April 2010 and March 2022. Primary outcomes were in-hospital mortality and complications. Secondary outcomes were opioid use postoperatively; readmission within 90 days, one year, and two years; and total hospitalization costs. We used propensity score overlap weighting models, with the acetaminophen group as the reference group.Aims

The number of revision arthroplasties being performed in the elderly is expected to rise, including revision for infection. The primary aim of this study was to measure the treatment success rate for octogenarians undergoing revision total hip arthroplasty (THA) for periprosthetic joint infection (PJI) compared to a younger cohort. Secondary outcomes were complications and mortality. Patients undergoing one- or two-stage revision of a primary THA for PJI between January 2008 and January 2021 were identified. Age, sex, BMI, American Society of Anesthesiologists grade, Charlson Comorbidity Index (CCI), McPherson systemic host grade, and causative organism were collated for all patients. PJI was classified as ‘confirmed’, ‘likely’, or ‘unlikely’ according to the 2021 European Bone and Joint Infection Society criteria. Primary outcomes were complications, reoperation, re-revision, and successful treatment of PJI. A total of 37 patients aged 80 years or older and 120 patients aged under 80 years were identified. The octogenarian group had a significantly lower BMI and significantly higher CCI and McPherson systemic host grades compared to the younger cohort.Aims

Periacetabular osteotomy (PAO) is widely recognized as a demanding surgical procedure for acetabular reorientation. Reports about the learning curve have primarily focused on complication rates during the initial learning phase. Therefore, our aim was to assess the PAO learning curve from an analytical perspective by determining the number of PAOs required for the duration of surgery to plateau and the accuracy to improve. The study included 118 consecutive PAOs in 106 patients. Of these, 28 were male (23.7%) and 90 were female (76.3%). The primary endpoint was surgical time. Secondary outcome measures included radiological parameters. Cumulative summation analysis was used to determine changes in surgical duration. A multivariate linear regression model was used to identify independent factors influencing surgical time.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. In a retrospective, cross-sectional study design, we gathered all patients with PJI (International Classification of Diseases (ICD)-10 code: T84.5) and resulting in-hospital treatment in Germany between 1 January 2019 and 31 December 2022. Data were provided by the Institute for the Hospital Remuneration System in Germany. Demographic data, in-hospital deaths, need for intensive care therapy, secondary diagnosis, complications, and use of diagnostic instruments were assessed. Odds ratios (ORs) with 95% confidence intervals (CIs) for in-hospital mortality were calculated.Aims
Methods
The aim of this meta-analysis was to determine the pooled incidence of postoperative urinary retention (POUR) following total hip and knee arthroplasty (total joint replacement (TJR)) and to evaluate the risk factors and complications associated with POUR. Two authors conducted searches in PubMed, Embase, Web of Science, and Scopus on TJR and urinary retention. Eligible studies that reported the rate of POUR and associated risk factors for patients undergoing TJR were included in the analysis. Patient demographic details, medical comorbidities, and postoperative outcomes and complications were separately analyzed. The effect estimates for continuous and categorical data were reported as standardized mean differences (SMDs) and odds ratios (ORs) with 95% CIs, respectively.Aims
Methods
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. We retrospectively reviewed 32 patients (22 hips and 11 knees) who underwent single-stage revision combined with IA carbapenem infusion between November 2013 and March 2020. The IA and intravenous (IV) carbapenem infusions were administered for a single Gram-negative infection, and IV vancomycin combined with IA carbapenems and vancomycin was applied for polymicrobial infection including Gram-negative bacteria. The bacterial community distribution, drug sensitivity, infection control rate, functional recovery, and complications were evaluated. Reinfection or death caused by PJI was regarded as a treatment failure.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. Patients aged ≥ 18 years with a traumatic CCS between January 2012 and December 2017 in Wales were identified. Patient demographics and data about injury, management, and outcome were collected. Statistical analysis was performed to assess mortality and between-group differences.Aims

This study aimed to investigate the risk of postoperative complications in COVID-19-positive patients undergoing common orthopaedic procedures. 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.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). All patients with PDFF primarily treated with DP, SP, or DFA between 2008 and 2022 at a university teaching hospital were included in this retrospective cohort study. The primary outcome was revision surgery for failure following DP, SP, or DFA. Secondary outcome measures included any reoperation, length of hospital stay, and mortality. All basic demographic and relevant implant and injury details were collected. Radiological analysis included fracture classification and evaluation of metaphyseal and medial comminution.Aims

The aim of this study was to determine whether early surgical treatment results in better neurological recovery 12 months after injury than late surgical treatment in patients with acute traumatic spinal cord injury (tSCI). Patients with tSCI requiring surgical spinal decompression presenting to 17 centres in Europe were recruited. Depending on the timing of decompression, patients were divided into early (≤ 12 hours after injury) and late (> 12 hours and < 14 days after injury) groups. The American Spinal Injury Association neurological (ASIA) examination was performed at baseline (after injury but before decompression) and at 12 months. The primary endpoint was the change in Lower Extremity Motor Score (LEMS) from baseline to 12 months.Aims

The February 2023 Hip & Pelvis Roundup360 looks at: Total hip arthroplasty or internal fixation for hip fracture?; Significant deterioration in quality of life and increased frailty in patients waiting more than six months for total hip or knee arthroplasty: a cross-sectional multicentre study; Long-term cognitive trajectory after total joint arthroplasty; Costal cartilage grafting for a large osteochondral lesion of the femoral head; Foley catheters not a problem in the short term; Revision hips still a mortality burden?; How to position implants with a robotic arm; Uncemented stems in hip fracture?
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. We identified all periprosthetic fractures around a hip or knee arthroplasty from our prospectively collated database between 2012 and 2021. Patients were categorized into early or delayed intervention based on time from admission to surgery (early = ≤ 36 hours, delayed > 36 hours). Patient demographics, existing implants, Unified Classification System fracture subtype, acute medical issues on admission, preoperative haemoglobin, blood transfusion requirement, and length of hospital stay were identified for all patients. Complication and mortality rates were compared between groups.Aims

The April 2024 Shoulder & Elbow Roundup360 looks at: Acute rehabilitation following traumatic anterior shoulder dislocation (ARTISAN): pragmatic, multicentre, randomized controlled trial; Prevalence and predisposing factors of neuropathic pain in patients with rotator cuff tears; Are two plates better than one? The clavicle fracture reimagined; A single cell atlas of frozen shoulder capsule identifies features associated with inflammatory fibrosis resolution; Complication rates and deprivation go hand in hand with total shoulder arthroplasty; Longitudinal instability injuries of the forearm; A better than “best-fit circle” method for glenoid bone loss assessment; 3D supraspinatus muscle volume and intramuscular fatty infiltration after arthroscopic rotator cuff repair.
The February 2023 Foot & Ankle Roundup360 looks at: Joint inflammatory response in ankle and pilon fractures; Tibiotalocalcaneal fusion with a custom cage; Topical application of tranexamic acid can reduce blood loss in calcaneal fractures; Risk factors for failure of total ankle arthroplasty; Pain catastrophizing: the same as pain forecasting?.
The aim of this study was to compare the migration of the femoral component, five years postoperatively, between patients with a highly cross-linked polyethylene (HXLPE) insert and those with a conventional polyethylene (PE) insert in an uncemented Triathlon fixed insert cruciate-retaining total knee arthroplasty (TKA). Secondary aims included clinical outcomes and patient-reported outcome measures (PROMs). We have previously reported the migration and outcome of the tibial components in these patients. A double-blinded randomized controlled trial was conducted including 96 TKAs. The migration of the femoral component was measured with radiostereometry (RSA) at three and six months and one, two, and five years postoperatively. PROMs were collected preoperatively and at all periods of follow-up.Aims

Implant-related postoperative spondylodiscitis (IPOS) is a severe complication in spine surgery and is associated with high morbidity and mortality. With growing knowledge in the field of periprosthetic joint infection (PJI), equivalent investigations towards the management of implant-related infections of the spine are indispensable. To our knowledge, this study provides the largest description of cases of IPOS to date. Patients treated for IPOS from January 2006 to December 2020 were included. Patient demographics, parameters upon admission and discharge, radiological imaging, and microbiological results were retrieved from medical records. CT and MRI were analyzed for epidural, paravertebral, and intervertebral abscess formation, vertebral destruction, and endplate involvement. Pathogens were identified by CT-guided or intraoperative biopsy, intraoperative tissue sampling, or implant sonication.Aims
