Late infection is the most frequent complications after hemiarthroplasty. Urinary tract infections are the only distant septic focus considered to be a risk factor in the literature. We retrospectively reviewed 460 patients with hip fracture treated by hemiarthroplasy over a period of one year. Preoperative positive urine dipsticks and urine analysis have been looked at as causes for delay of surgery in absence of clinical manifestations of urinary tract infection. 367 patients were operated within 24 hours. 78 patients were delayed more than 78 hours. Urinary tract infection had the least contribution as a cause of delay. 99 patients had preoperative urinary tract infection and 57 patients had postoperative wound infection. Of these with postoperative surgical site infection, 31 patients did not show any evidence of preoperative urinary tract infection, 23 patients had preoperative urinary tract infection, two had leg ulcer and one had chest infection. 13 patients had chronic urinary tract infection and five patients had the same causative organism in urine & wound. The most common organisms of urinary infection are E. Coli, mixed growth, Enteroccocus Faecalis, Pseudomonas and others. The most causative organism of the postoperative surgical site infection are Staph aureus including MRSA, mixed growth including Staph. Epidermidis, Enteroccocus Faecalis and others There is no direct significant correlation between preoperative urinary tract infection and surgical site infection. We recommend that preoperative urinary tract infection should be treated as a matter of urgency but it should not delay hip fracture surgery unless it is causing symptoms

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 urinary tract infection post hip fracture surgery. There are little data surrounding the effects of post-operative urinary tract infections on mortality and deep prosthetic infection. We prospectively investigated the impact of post-operative urinary tract infection (UTI) in 9168 patients admitted to our institution with a diagnosis of proximal femoral fracture over an eleven year period in a prospective population study. We examined the effects of post operative UTI on the incidence of deep infection, survivorship and length of stay. Post-operative UTI occurred in 6.1% (n=561) and deep infection in 0.89% (n=82). Deep infection was significantly more common in patients complicated with a UTI (3.2% vs 0.74% p< 0.001) with a relative risk of 3.7:1. In 58% of patients the same organisms was cultured in the urine and hip samples. A postoperative UTI did not adversely effect 90 day survival, however was associated with an increased length of stay (ROC analysis AUC=0.79). Delays to surgery and age were not predictive of a post operative UTI. Recognition of the risks posed by post operative UTI, the risk factors for development of infection and early treatment is essential to reduce the risks of increased subsequent periprosthetic infection

Aims. Frailty has been gathering attention as a factor to predict surgical outcomes. However, the association of frailty with postoperative complications remains controversial in spinal metastases surgery. We therefore designed a prospective study to elucidate risk factors for postoperative complications with a focus on frailty. Methods. We prospectively analyzed 241 patients with spinal metastasis who underwent palliative surgery from June 2015 to December 2021. Postoperative complications were assessed by the Clavien-Dindo classification; scores of ≥ Grade II were defined as complications. Data were collected regarding demographics (age, sex, BMI, and primary cancer) and preoperative clinical factors (new Katagiri score, Frankel grade, performance status, radiotherapy, chemotherapy, spinal instability neoplastic score, modified Frailty Index-11 (mFI), diabetes, and serum albumin levels). Univariate and multivariate analyses were developed to identify risk factors for postoperative complications (p < 0.05). Results. Overall, 57 postoperative complications occurred in 47 of 241 (19.5%) patients. The most common complications were wound infection/dehiscence, urinary tract infection, and pneumonia. Univariate analysis identified preoperative radiotherapy (p = 0.028), mFI (p < 0.001), blood loss ≥ 500 ml (p = 0.016), and preoperative molecular targeted drugs (p = 0.030) as potential risk factors. From the receiver operating characteristic curve, the clinically optimal cut-off value of mFI was 0.27 (sensitivity, 46.8%; specificity, 79.9%). Multivariate analysis identified mFI ≥ 0.27 (odds ratio (OR) 2.94 (95% CI 1.44 to 5.98); p = 0.003) and preoperative radiotherapy (OR 2.11 (95% CI 1.00 to 4.46); p = 0.049) as significant risk factors. In particular, urinary tract infection (p = 0.012) and pneumonia (p = 0.037) were associated with mFI ≥ 0.27. Furthermore, the severity of postoperative complications was positively correlated with mFI (p < 0.001). Conclusion. The mFI is a useful tool to predict the incidence and the severity of postoperative complications in spinal metastases surgery. Cite this article: Bone Joint J 2024;106-B(12):1469–1476

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 urinary tract infections were diagnosed more frequently when time to surgery increased. Conclusion. Longer time to surgery due to non-medical reasons was associated with a higher incidence of postoperative pressure sores and urinary tract infections when time to surgery was more than 48 hours after admission. No association was found between time to surgery and 30-day mortality rates or postoperative length of hospital stay. Cite this article: Bone Joint J 2022;104-B(12):1369–1378

Urinary tract infection is a source of organisms responsible for deep infection of hip and knee joint prostheses. In an attempt to reduce the occurrence of post operative urinary sepsis, some orthopaedic surgeons insert indwelling urethral catheters (IDC) immediately prior to surgery with the aim of avoiding urine retention. The purpose of this study was to determine if preoperative indwelling urethral catheterisation reduces the incidence of urine retention following total hip and total knee arthroplasty. 124 patients who underwent total hip and total knee arthroplasty in New Plymouth between April 2001 and July 2002, were randomly allocated to either have an indwelling urethral catheter inserted preoperatively (IDC group), or no catheter (control group). Prior to surgery all patients completed a questionnaire enquiring about a history of urinary obstructive symptoms, or previous urinary tract infection. The two groups were compared with regard to demographic data, questionnaire findings and the amount of post operative opiate usage. The primary outcome measure for the study was post operative urine retention. Urinary tract infection post operatively was considered as a secondary outcome measure. No difference was noted between the two groups with regard to age sex arthroplasty type, history of urinary obstruction, or previous urinary tract infection. Post operative urinary retention occurred in a significantly less number of patients in the IDC group compared with the control group. No difference in post operative urinary tract infection was noted between the groups with the sample size used in this study. Our study suggests that the prophylactic use of indwelling urethral catheters prior to total hip and total knee arthroplasty is effective in reducing the occurrence of post operative urine retention

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, urinary tract infection, and blood transfusion. Conclusion. This study defines the contemporary characteristics of primary malignancies resulting in metastatic bone disease. These data should be considered by surgeons when prognosticating patient outcomes during treatment of their metastatic bone disease. Cite this article: Bone Jt Open 2023;4(6):424–431

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 urinary tract infection (odds ratio (OR) 2.78, 95% confidence interval (CI) 1.57 to 4.92; p < 0.001) and increasing delay to theatre for treatment of the fracture (OR 1.31 per day, 95% CI 1.12 to 1.52; p < 0.001) were predictors of developing a SSI, while a cemented arthroplasty was protective (OR 0.54, 95% CI 0.31 to 0.96; p = 0.031). In all, nine patients (20.9%) were alive at one year with a functioning hemiarthroplasty following DAIR, 20 (46.5%) required multiple surgical debridements after an initial DAIR, and 18 were converted to an excision arthroplasty due to persistent infection, with six were alive at one year. The culture of any gram-negative organism reduced success rates to 12.5% (no cases were successful with methicillin-resistant Staphylococcus aureus or Pseudomonas infection). Favourable organisms included Citrobacter and Proteus (100% cure rate). The all-cause mortality at one year after deep SSI was 55.87% versus 24.9% without deep infection. Conclusion. Deep infection remains a devastating complication regardless of the treatment strategy employed. Success rates of DAIR are poor compared to total hip arthroplasty, and should be reserved for favourable organisms in patients able to tolerate multiple surgical procedures.

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

Aims. 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), urinary tract infection (UTI; RR 2.58, 95% CI 1.03 to 6.43), and 30-day readmission (RR 1.45, 95% CI 1.33 to 1.59). There was insufficient evidence for assessing an association between MetS and venous thromboembolism events, pulmonary or gastrointestinal complications, or mortality. Conclusion. Patients with MetS undergoing THA and TKA are at increased risk of all-cause complications, cardiovascular complications, SSI, UTI, and 30-day readmission. Surgeons should be aware of the increased risk of these complications in MetS, and presurgical protocols for these complications should give special consideration to MetS patients.

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 urinary tract infection (3.9 vs. 5.9%, p< 0.001) was seen in patients delayed by over 36 hours. However, when considering all patients together, an increase in both urinary tract infection (3.9% vs. 6.1%, p< 0.001) and chest infections (7.9% vs. 11.3%, p< 0.001) was seen with over 36 hours delay to surgery. Conclusions. The 30-day mortality following hip fracture surgery is 9.5%. Patients admitted without co-morbidities have significantly increased mortality when surgery is delayed by over 5 days. A 36 hour delay to surgery significantly increases length of stay. Urinary tract infection was the only post-operative morbidity to rise with delay to surgery in fit patients

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 infections (29%), urinary tract infections (21%) and surgical site infections (9%). This is the largest cohort of surgically treated hip fracture from South Africa. Proportions of patients receiving different surgical interventions such as THR are comparable to the broader literature. However a number of key performance indicators such as surgery within 36 hours are challenging to meet. Given the changing demographics of South Africa, this study provides an early insight to contemporary care and may help provide direction for broader national strategies for reporting and improving hip fracture care

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 infection, urinary tract infection, pneumonia) (18%, n=9/49) and implant failure (14%, n=7/49) were the most frequently described in the FRI group. Conclusions. Patients who suffered from an FRI have a decreased QoL in comparison to those without an FRI. Moreover, patients with an FRI have a higher rate of additional complications. These findings can help in patient counselling regarding the potential physical and mental consequences of having a complicated course of recovery due to an infection

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), urinary tract infection (SHR 1.89, 95%CI 1.02-3.5, p=0.04) and dementia (SHR 9.4, 95%CI 2.89-30.58,p<0.001) as significant risk factors for developing HHA-PJI. When infection treatment was successful (n=15, 38%), median survival was 1632 days (IQR 829-2084), as opposed to 215 days (IQR 20-1245) in those who failed, with a 90-day mortality of 30%(n=12). There was no significant difference in success among debridement, excision arthroplasty or revision arthroplasty. HHA PJI is uncommon but highly lethal. All currently identified predictors are non-modifiable. Due to the common polymicrobial and MDRO infections our standard antibiotic prophylaxis may not be adequate HHA-PJI is a different disease compared to elective PJI with distinct epidemiology, pathogens, risk factors and outcomes, which require targeted research specific to this unique population

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

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 urinary tract infection (UTI) and post-operative urinary retention (POUR). Ninety-five percent of patients found the catheter to be convenient. Only 5% of patients reported any pain with catheter use. On the contrary, 47.5% of non-catheterized patients found it difficult to move to the bathroom and 30.4% found it difficult to urinate. Catheterized patients had significative less pain than uncatheterized patients (0.62/10 vs 2.45/10 respectively, p < 0 .001). The use of nerve block reduced pain levels amongst catheterized patients but was not associated with reduced pain levels or satisfaction amongst non-catheterized patients. The use of catheter was not associated with increased risk of UTI(17.5% in the catheterized vs 13.3% in the non-catheterized, p = 0.541) or POUR (6.8% in the catheterized vs 11.1% in the non-catheterized, p = 0.406). This study illustrates the benefits and safety associated with the use of urinary catheters in the pre-operative period amongst hip fractures. The use of catheters was associated with reduced pain and satisfaction without increasing post-operative UTI or POUR. These findings suggest that pre-operative catheter use is associated with less pain and more satisfaction for patients awaiting hip surgery and whom other measures, such as nerve blocks, are unlikely to reduce the discomfort associated with the mobility required to void. A prospective randomized control study could lead to a more evidence based approach for perioperative foley catheter usage in hip fracture patients

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 urinary tract infection showed some form of post-operative delayed wound healing or confirmed infection, versus 16% in the other sub-group, giving a relative risk of wound complications of 2:1. There was also an increase in confirmed infection in oozing wounds; 53% positive wound swabs versus 37% in those without a cultured urinary tract infection. A chi-squared analysis yielded a value of 6.07, giving a p value <0.02. There is therefore a statistically significant correlation between a positive urine culture and poor surgical outcome. Conclusion. Pre-operative urine screening and culture has a demonstrable correlation with post-operative surgical outcome. In the light of this study pre-operative urine culture should be mandatory for all pre-operative orthopaedic patients. It should be recognised that patients who present to pre-admission with a UTI are a high risk subgroup for wound infection post-operatively and this should be taken into account when consenting patients for surgery

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 urinary tract infections, and secondary outcome measures such as Gravol and Benadryl usage. Results: Comparison of the two well-matched groups demonstrated that patients who received spinal epimorph had increased rates of foley insertion (p=0.0026), foley duration (p=0.015), oxygen usage (p=0.0053), documented puritis (p=0.0006) and Benadryl usage (p=0.0053). Trends towards increased nausea/vomiting (p=0.17), antiemetic use (p=0.16) and urinary tract infections (p=0.15) were seen in the spinal epimorph group, although these differences did not reach statistical significance. Conclusion: The use of spinal epimorph as part of an analgesia protocol surrounding total joint arthroplasty is associated with increased complications and patient discomfort when compared to patients who received continuous local infiltrative analgesia. Further research is needed to determine if alternate modes of analgesia provide adequate pain relief when compared with spinal epimorph and thus provide suitable alternatives with less complications

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 urinary tract infection. We prospectively determined if we could identify patients needing pre-operative catheterisation. Method: 150 consecutive patients undergoing knee and hip arthroplasty were recruited. Pre-operative symptoms of frequency, nocturia, retention, incontinence and previous bladder or prostate surgery along with prior history of catheterisation were recorded. The type of anaesthesia and post-operative analgesia was noted. Details of catheterisation included duration, antibiotic administration, and reason for catheterisation and incidence of urinary tract infection. Results: Patients mean age was 67.7 years. 47 patients required catheterisation of which 56.6% were female. The mean age of patients catheterised was 70.6 years in comparison to 66.3 years (Mann-Whitney P< 0.01). The frequency of catheterisation was unrelated to the surgical procedure. Nocturia was significantly more common in-patients requiring catheterisation (Kruskal Wallis P=0.04) and its combination with pre-operative symptoms of frequency, retention or incontinence increased the significance further to P=0.001. Patient age of greater then 66 years had a 76.6% predictive value for the subsequent need of catheterisation. This further increased to 91.5% when combined with a previous history of either catheterisation or nocturia. The type of anaesthesia or the post-operative analgesia did not significantly influence catheterisation frequency. Conclusion: Patients aged greater then 66 years undergoing joint arthroplasty with previous history of catheterisation or nocturia may benefit from pre-operative bladder catheterisation. Peri-operative catheterisation of high-risk patients in theatre reduces patient discomfort caused by the observation period and avoids bladder atonia consequent of the distention, which may subsequently prolong catheterisation

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 < 48h 43.1 d, > 48h 54.5 d). 100% of patients developed respiratory tract infections. 56.3% of patients developed urinary tract infections (33% in patients doing corticosteroids during 24h, 70% in those who did 48h). Mean duration of mechanic ventilation was 20.3 days (anterior approach 19.3 d, posterior approach 19.8 d; steroids during 24h 16.7 d, steroids during 48h 21 d; time until surgery < 48h 13.6 d, > 48h 23 d). In 37.5% of patients a traqueostomy was performed (41.7% in patients submitted to anterior approach, 25% in posterior approach; 16.7% in patients doing steroids during 24h, 50% in those who did 48h; time until surgery < 48h 28.6%, > 48h 50%). Discussion: This patients are associated with long hospitalization and mechanic ventilation periods. Respiratory tract infection was the most frequent complication. The surgical approach had no influence on mechanic ventilation periods. Those submitted to anterior approach had longer hospitalization periods and higher incidence of traqueostomy. Patients who did corticosteroids during 48h had higher incidence of urinary tract infections and traqueostomy, and longer mechanic ventilation periods. Those operated less than 48h after trauma had shorter hospitalization and mechanic ventilation periods and traqueostomy procedure. Conclusion: Steroids longer than 24h, anterior cervical approach and time to surgery > 48h tend to be associated with higher complication rates

Aims. Urinary catheter use in the peri-operative and post-operative phase following arthroplasty may be associated with increased risk of urinary tract infection (UTI) and deep prosthetic joint infection (PJI). These can be catastrophic complications in joint arthroplasty. We performed a systematic review of the evidence on routine use of antibiotics for urinary catheter insertion and removal following arthroplasty. Methods. Electronic databases were searched using the HDAS interface. Grey literature was also searched. From 219 citations, six studies were deemed eligible for review. Due to study heterogeneity a narrative approach was adopted. Methodological quality of each study was assessed using the CASP appraisal tool. Included studies were found to have moderate to good methodological quality. Results. A total of 4696 hip and knee arthroplasties were performed on 4578 participants across all studies. Of these 1475 (31%) were undertaken on men and 3189 (68%) on women. The mean age of the study participants was 69 years. 3489 cases (74.3%) related to hip arthroplasty and 629 of cases (13.4%) to knee arthroplasty. 578 cases (12.3%) specified either hip or knee arthroplasty. In total, 45 PJIs were reported across all studies (0.96%). Two of the studies found either no PJI or no statistical difference in the rate of PJI when antibiotic prophylaxis was not used for catheter manipulation. Where studies report potential haematogenous spread from UTIs, this association can only be assumed. Rates of bacteriuria varied greatly between studies and depend on timing of sample and gender. Increased duration of urinary catheterisation is positively associated with UTI. Conclusion. It remains difficult to justify the routine use of prophylactic antibiotics for catheter manipulation in well patients undergoing arthroplasty. Their use is not recommended for this indication
