Frailty has been shown to be a risk predictor for peri-operative adverse events (AEs) in patients undergoing various type of spine surgery. However, its relationship with Patient Related Outcome Measures (PROMS) remains unknown. The primary objective of this study was to determine the impact of frailty on PROMS in patients undergoing surgery for thoraco-lumbar degenerative conditions. The secondary objective was to determine the association between frailty and baseline PROMS. This is a retrospective study of a prospective cohort of patients >55 years old who underwent surgery between 2012 and 2018. Patient data and PROMS (EQ-5D, SF-12, ODI, back and leg pain NRS) were extracted from the Canadian Spine Outcomes and Research Network registry for a single academic centre. Frailty was retrospectively calculated using the modified frailty index (mFI) and patient were classified as frail, pre-frail and non-frail. Patient characteristics and outcomes were analyzed using ANOVA or Kruskal-Wallis test for continuous variables and Chi square or Fisher's exact test for proportions. A generalized estimating equations (GEEs) regression model was used to assess the association between patients' baseline frailty status and PROMs measures at three and 12 months. 293 patients were included with a mean age of 67 ± 7 years. Twenty-two percent of the patients (n= 65) were frail, 59 % (n=172) were pre-frail and 19% (n=56) were non-frail. At baseline, the three groups had similar PROMS, except for the PCS which was worse in the frail group (mean difference [95% CI], −4.9 [−8.6;-1.1], p= 0.0083). The improvement in the EQ-5D, PCS, MCS, ODI, back and leg pain NRS scores was not significantly different between the three groups (p> 0.05). The was no difference in the evolution of the PROMS at three and 12 months between the three groups (p> 0.05). Although frailty is a known predictor of AEs, it does not predict worse PROMS after spine surgery in that population. At baseline, non-frail, pre-frail and frail patients have similar PROMS

En bloc resection for primary bone tumours and isolated metastasis are complex surgeries associated with a high rate of adverse events (AEs). The primary objective of this study was to explore the relationship between frailty/sarcopenia and major perioperative AEs following en bloc resection for primary bone tumours or isolated metastases of the spine. Secondary objectives were to report the prevalence and distribution of frailty and sarcopenia, and determine the relationship between these factors and length of stay (LOS), unplanned reoperation, and 1-year postoperative mortality in this population. This is a retrospective study of prospectively collected data from a single quaternary care referral center consisting of patients undergoing an elective en bloc resection for a primary bone tumour or an isolated spinal metastasis between January 1st, 2009 and February 28th, 2020. Frailty was calculated with the modified frailty index (mFI) and spine tumour frailty index (STFI). Sarcopenia, determined by the total psoas area (TPA) vertebral body (VB) ratio (TPA/VB), was measured at L3 and L4. Regression analysis produced ORs, IRRs, and HRs that quantified the association between frailty/sarcopenia and major perioperative AEs, LOS, unplanned reoperation and 1-year postoperative mortality. One hundred twelve patients met the inclusion criteria. Using the mFI, five patients (5%) were frail (mFI ³ 0.21), while the STFI identified 21 patients (19%) as frail (STFI ³ 2). The mean CT ratios were 1.45 (SD 0.05) and 1.81 (SD 0.06) at L3 and L4 respectively. Unadjusted analysis demonstrated that sarcopenia and frailty were not significant predictors of major perioperative AEs, LOS or unplanned reoperation. Sarcopenia defined by the CT L3 TPA/VB and CT L4 TPA/VB ratios significantly predicted 1-year mortality (HR of 0.32 per one unit increase, 95% CI 0.11-0.93, p=0.04 vs. HR of 0.28 per one unit increase, 95% CI 0.11-0.69, p=0.01) following unadjusted analysis. Frailty defined by an STFI score ≥ 2 predicted 1-year postoperative mortality (OR of 2.10, 95% CI 1.02-4.30, p=0.04). The mFI was not predictive of any clinical outcome in patients undergoing en bloc resection for primary bone tumours or isolated metastases of the spine. Sarcopenia defined by the CT L3 TPA/VB and L4 TPA/VB and frailty assessed with the STFI predicted 1-year postoperative mortality on univariate analysis but not major perioperative AEs, LOS or reoperation. Further investigation with a larger cohort is needed to identify the optimal measure for assessing frailty and sarcopenia in this spine population

Introduction. Open fragility ankle fractures involve complex decision making. There is no consensus on the method of surgical management. Our aim in this study was to analyse current management of these patients in a major trauma centre (MTC). Materials & Methods. This cohort study evaluates the management of geriatric (≥65years) open ankle fractures in a MTC (November 2020–November 2022). The method, timing(s) and personnel involved in surgical care were assessed. Weightbearing status over the treatment course was monitored. Patient frailty was measured using the clinical frailty score (CFS). Results. There were 35 patients, mean age 77 years (range 65–97 years), 86% female. Mean length of admission in the MTC was 26.4 days (range 3–78). Most (94%) had a low-energy mechanism of injury. Only 57% of patients underwent one-stage surgery (ORIF n=15, hindfoot nail n=1, external frame n=4) with 45% being permitted to fully weightbear (FWB). Eleven (31.4%) underwent two-stage surgery (external fixator; ORIF), with 18% permitted to FWB. Of those patients with pre-injury mobility, 12 (66%) patients were able to FWB following definitive fixation. Delay in weightbearing ranged from 2–8weeks post-operatively. Seven patients (20%) underwent an initial Orthoplastic wound debridement. Ten patients (28.6%) required plastic surgery input (split-skin grafts n=9, local or free flaps n=3), whereby four patients (40%) underwent one stage Orthoplastic surgery. Eighteen (51.4%) patients had a CFS ≥5. Patients with a CFS of ≥7 had 60% 90-day mortality. Only 17% patients had orthogeriatrician input during admission. Conclusions. These patients have high frailty scores, utilise a relatively large portion of resources with multiple theatre attendances and protracted ward occupancy in an MTC. Early FWB status needs to be the goal of treatment, ideally in a single-staged procedure. Poor access to orthogeriatric care for these frail patients may represent healthcare inequality

Total hip arthroplasty (THA) is performed under general anesthesia (GA) or spinal anesthesia (SA). The first objective of this study was to determine which patient factors are associated with receiving SA versus GA. The second objective was to discern the effect of anesthesia type on short-term postoperative complications and readmission. The third objective was to elucidate factors that impact the effect of anesthesia type on outcome following arthroplasty. This retrospective cohort study included 108,905 patients (median age, 66 years; IQR 60-73 years; 56.0% females) who underwent primary THA for treatment of primary osteoarthritis in the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database during the period of 2013-2018. Multivariable logistic regression analysis was performed to evaluate variables associated with anesthesia type and outcomes following arthroplasty. Anesthesia type administered during THA was significantly associated with race. Specifically, Black and Hispanic patients were less likely to receive SA compared to White patients (White: OR 1.00; Black: OR 0.73; 95% confidence interval [CI] 0.71-0.75; Hispanic: OR 0.81; CI, 0.75-0.88), while Asian patients were more likely to receive SA (OR 1.44, CI 1.31-1.59). Spinal anesthesia was associated with increased age (OR 1.01; CI 1.00-1.01). Patients with less frailty and lower comorbidity were more likely to receive SA based on the modified frailty index ([mFI-5]=0: OR 1.00; mFI-5=1: OR 0.90, CI 0.88-0.93; mFI-5=2 or greater: OR 0.86, CI 0.83-0.90) and American Society of Anesthesiologists (ASA) class (ASA=1: OR 1.00; ASA=2: OR 0.85, CI 0.79-0.91; ASA=3: OR 0.64, CI 0.59-0.69; ASA=4-5: OR 0.47; CI 0.41-0.53). With increased BMI, patients were less likely to be treated with SA (OR 0.99; CI 0.98-0.99). Patients treated with SA had less post-operative complications than GA (OR 0.74; CI 0.67-0.81) and a lower risk of readmission than GA (OR 0.88; CI 0.82-0.95) following THA. Race, age, BMI, and ASA class were found to affect the impact of anesthesia type on post-operative complications. Stratified analysis demonstrated that the reduced risk of complications following arthroplasty noted in patients treated with SA compared to GA was more pronounced in Black, Asian, and Hispanic patients compared to White patients. Furthermore, the positive effect of SA compared to GA was stronger in patients who had reduced age, elevated BMI, and lower ASA class. Among patients undergoing THA for management of primary osteoarthritis, factors including race, BMI, and frailty appear to have impacted the type of anesthesia received. Patients treated with SA had a significantly lower risk of readmission to hospital and adverse events within 30 days of surgery compared to those treated with GA. Furthermore, the positive effect on outcome afforded by SA was different between patients depending on race, age, BMI, and ASA class. These findings may help to guide selection of anesthesia type in subpopulations of patients undergoing primary THA

Ankle fractures in the elderly are common and have a mortality rate of 12% within the first year. Treatment is challenging due to osteoporotic bone and patient co-morbidities. Many patients struggle with non-weight-bearing (NWB) and presently there is no consensus in the literature regarding optimum management of these injuries. We hypothesised that early weight-bearing in frail patients, Clinical Frailty scale (CFS) score of 4 or more will reduce morbidity and allow patients to return to their usual place of residence faster without jeopardising clinical outcome. We conducted a retrospective analysis of 80 patients aged over 65 years managed at Fiona Stanley Hospital for ankle fractures between January 2016 and 2018. Patients were divided into two cohorts: 40 patients managed NWB and 40 who were permitted to weight-bear as tolerated (WBAT). Patients were stratified as fit (CFS 1–3) or frail (CFS 4+). Primary outcomes were one-year mortality, return to primary residence at six weeks and complications. Secondary outcomes included length of acute hospital stay and rehab stay. For frail patients, those managed NWB stayed in rehab for 19 days longer (p=0.03) and had 28% more complications (p=0.03). By 6 weeks, fewer patients returned to full weight-bearing (p=0.03) and fewer patients had returned home (p=0.01). For fit patients, there were no significant differences in primary outcomes between NWB and WBAT. Our novel study categorising patients by CSF demonstrates that early mobilisation in frail patients results in improved outcomes. Currently there is no formal treatment protocol for the management of ankle fractures in the elderly, and we hope that our proposed algorithm will assist surgeons at our institution and elsewhere. Our study suggests that WBAT may benefit frail patients. We propose a protocol to assist in the management of geriatric ankle fracture patients based on clinical frailty scores

Fractures of the neck of femur are common in the older adult with significant morbidity and mortality rates. This patient cohort is associated with frailty and multiple complex medical and social needs requiring a multidisciplinary team to provide optimal care. The aim of this study was to assess the outcomes at 5 years following implementation of a collaborative service between the Orthopaedic and Geriatric departments of Southland Hospital in 2012. Retrospective data was collected for patients aged 65 years and older who were admitted with a fragility hip fracture. Data was collated for 2011 (pre-implementation) and 2017 (post-implementation). Demographics and ASA scores were recorded. We assessed 30-day and 1-year mortality, surgical data, length of stay and complications. There were 74 patient admissions in 2011 and 107 in 2017. Mean age at surgery was 84.2 years in 2011 and 82.6 years in 2017 (p>0.05). Between the 2011 and 2017 groups there has been a non-significant reduction in length of stay on the orthopaedic ward (9.8 days vs 7.5 days, p=0.138) but a significant reduction in length of stay on the rehabilitation ward (19.9 vs 9 days, p<0.001). There was a significant decrease in frequency of patients with a complication (71.6% vs 57%, p=0.045) and a marginal reduction in number of complications (p=0.057). Through logistic regression controlling for age, sex and ASA score, there was a reduction in the odds of having a complication by 12% between 2011 and 2017 (p<0.001). There was no difference in mortality between the groups. The orthogeriatric model of care at Southland Hospital appears to have reduced both the frequency of complications and length of stay on the rehabilitation ward 5 years after its implementation. This is the first study in New Zealand demonstrating medium-term post-implementation follow-up of what is currently a nationally accepted standard model of care

Background. Periprosthetic joint infection (PJI) following total knee arthroplasty (TKA) is a severe complication in terms of disability, morbidity, and cost. We performed a study to investigate whether early PJI (within 90 days of primary TKA) is associated with increased mortality. Secondary aims were to compare mortality rates over time and between surgical treatment methods. Methods. Patients with suspected PJI were identified by linkage of the Swedish Knee Arthroplasty Register (SKAR) and the Swedish Prescribed Drug Register (SPDR) in 2007–2008 and 2012–2013. Medical records of patients receiving more than 4 weeks of continuous antibiotic therapy were subsequently reviewed to verify the PJI diagnosis. Information on mortality was obtained through the SKAR which is updated daily from the tax agency and patients with PJI were compared to patients without PJI. Results. 466 patients were diagnosed with PJI within 90 days and compared to 40,362 patients without PJI. Mortality rates were significantly higher for PJI patients in both short- and long term: 2.6% vs. 0.8% at 1 year, 4.9% vs. 1.9% at 2 years, 15.7% vs. 7.1% at 5 years, and 38% vs. 21.4% at 10 years. The difference in mortality rate remained after adjusting for sex, age, diagnosis, and time period for surgery with Hazard Ratio 1.8 (95% CI:1.6–2.1). Mortality rates did not differ between time periods, and we found no correlation to surgical treatment. Conclusion. Patients with early PJI after primary TKA have an increased mortality rate compared to TKA patients without PJI. Improvements in surgical treatment strategy has not resulted in better survival. Long term difference in mortality rates indicates that PJI is not the sole reason for mortality suggesting a general frailty in PJI patients

Aims. Hip fracture patients are at higher risk of severe COVID-19 illness, and admission into hospital puts them at further risk. We implemented a two-site orthopaedic trauma service, with ‘COVID’ and ‘COVID-free’ hubs, to deliver urgent and infection-controlled trauma care for hip fracture patients, while increasing bed capacity for medical patients during the COVID-19 pandemic. Methods. A vacated private elective surgical centre was repurposed to facilitate a two-site, ‘COVID’ and ‘COVID-free’, hip fracture service. Patients were screened for COVID-19 infection and either kept at our ‘COVID’ site or transferred to our ‘COVID-free’ site. We collected data for 30 days on patient demographics, Clinical Frailty Scale (CFS), Nottingham Hip Fracture Scores (NHFS), time to surgery, COVID-19 status, mortality, and length of stay (LOS). Results. In all, 47 hip fracture patients presented to our service: 12 were admitted to the ‘COVID’ site and 35 to the ‘COVID-free’ site. The ‘COVID’ site cohort were older (mean 86.8 vs 78.5 years, p = 0.0427) and with poorer CFS (p = 0.0147) and NHFS (p = 0.0023) scores. At the ‘COVID-free’ site, mean time to surgery was less (29.8 vs 52.8 hours, p = 0.0146), and mean LOS seemed shorter (8.7 vs 12.6 days, p = 0.0592). No patients tested positive for COVID-19 infection while at the ‘COVID-free’ site. We redirected 74% of our admissions from the base ‘COVID’ site and created 304 inpatient days’ capacity for medical COVID patients. Conclusion. Acquisition of unused elective orthopaedic capacity from the private sector facilitated a two-site trauma service. Patients were treated expeditiously, while successfully achieving strict infection control. We achieved significant gains in medical bed capacity in response to the COVID-19 demand. The authors propose the repurposing of unused elective operating facilities for a two-site ‘COVID’ and ‘COVID-free’ model as a safe and effective way of managing hip fracture patients during the pandemic.

Seniors make up 16.9 percent of the Canadian population. Furthermore, the number of Canadians who are 65 years or older is increasing at an average rate of 20 percent every 5 years. In 2017, Sing etal reported that there is an increasing number of patients undergoing degenerative scoliosis surgery with the largest increase attributed to patients aged 65–69 years followed by those aged 70–74 years. Therefore, the purpose of this study is to assess the effectiveness of undergoing spinal surgery to correct degenerative spinal scoliosis in the ever-growing number of elderly patients. We hypothesize that age is not an independent prognostic factor of patients' outcomes followings degenerative scoliosis surgery. A retrospective review of prospectively collected data within the Canadian Spine Outcome and Research Network (CSORN) was conducted. Data was analyzed using IBM-SPSS. ANOVA was used to analyze continuous variables while Chi Square test was used to analyze categorical variables. Significance level was p < 0.05. There were 165 patients identified from the registry who met the inclusion criteria, 94 patients (57 %) were female. There were 102 (61.8 %) patients who were 65 years or older. The overall average age was 66.6 years (range 35–84, SD 8.6). There were 27 intra-operative complications, 44 peri-operative complications and 18 post operative complications. There was no statistically significant difference between the two age groups with regards to risk of developing intra-operative, perioperative and post operative complications. Patients who underwent degenerative scoliosis surgery reported an average improvement of 2.95±3.32, 3.64±3.50, 16.84±20.44 points on the back-pain scale, leg pain scale and the Oswestry Disability Index (ODI) respectively, there was no statistically significant differences in these measures between the two age groups. As the number of patients undergoing degenerative scoliosis surgery increases, clinicians will need to determine which factors will significantly impact patients' outcomes following surgery. This study shows that age is not an independent prognostic factor when it comes to patients' outcomes following degenerative scoliosis surgery. In the future, research should examine the impact of age in conjunction with factors such as frailty, comorbidities and functional status on patient outcomes

Introduction. The global rapid growth of the aging population has some likelihood to create a serious crisis on health-care and economy at an unprecedented pace. To extend Healthy Life Expectancy (HALE) in a number of countries, it is desired more than ever to investigate characteristic and prognosis of numerous diseases. This enlightenment and recent studies on patient-reported outcome measures (PROMs) will drive the increasing interest in the quality of life among the world. The demand for primary THAs by 2030 would rise up to 174% in USA. It is expected that the number of the elderly will surge significantly in the future, thus more septuagenarian and octogenarian are undergoing THA. Moreover, HALE of Japanese female near the age of 75 years, followed to Singapore, is still increasing. Therefore, concerns exist about the PROMs of performing THA in this age-group worldwide. Nevertheless almost the well-established procedure, little agreement has been reached to the elderly. We aimed to clarify the mid-term PROMs after THA over 75-year old. Methods. Between 2005 and 2013, we performed 720 consecutive primary cemented THAs through a direct lateral approach. Of these, 503 female patients (655 hips) underwent THA for treatment of osteoarthritis, with a minimum follow-up of 5 years, were retrospectively enrolled into the study. We excluded 191 patients (252 hips) aged less than 65-year at the time of surgery and 58 patients (60) because of post-traumatic arthritis or previous surgery (37), or lack of data (23). Thus, 343 hips remained eligible for our study, contributed by 254 patients. We investigated Quality-adjusted life year (QALY), EuroQol 5-Dimension 5-Level scale (EQ-5D) and the Japanese Orthopaedic Association Hip-Disease Evaluation Questionnaire (JHEQ, which was a disease-specific and self-administered questionnaire, reflecting the specificity of the Japanese cultural lifestyle) in patients aged 75 years or older (154 hips, Group-E) compared with those aged 65 to 74 years (189 hips, Group-C) retrospectively. We evaluated the association between patients aged 75 years or older and the following potential risk factors, using logistic regression analysis: age, number of vertebral fractures (VFs), American Society of Anesthesiologists physical status (ASA-PS) and Charlson Comorbidity Index (CCI). A p value of < 0.05 was considered significant for the Mann-Whitney U test. Results. At a mean follow-up duration of 7.2 years, QALY, EQ-5D and JHEQ for the domain of patient satisfaction were significantly greater for Group-E than Group-C; however, there were no significant differences in JHEQ for pain, movement and mental-health between groups. On multivariate analysis, the age (odds ratio [OR] 2.48, p < .01 for EQ-5D; OR .32, p < .01 for JHEQ satisfaction), VFs (OR 1.63, p < .01 for satisfaction) and ASA-PS (OR .64, p = .31 for EQ-5D) were independent predictive risk factors for patients aged 75-year or older. Conclusions. Based on mid-term follow-up of PROMs study, we suggest that cemented THA can lead to the extension of HALE towards the super aged society and our results can be applied to a systematic analysis for the Global Burden of Disease Study related frailty

The aim of this study was to assess the incidence, management and survival of unstable pelvic ring injuries in patient aged 65 years or older. Prospectively kept data was analysed from April 2008 to October 2016. Information regarding the mechanism, fracture type, associated injuries, treatment and complications of the treatment were collected. Annual incidence was calculated and a Kaplan Meier survival analysis for carried out at 30 days, 1 year and 5 years. 404 patient records were available. 125 were 65 years or older (60 males and 65 females). 24 (19%) patients required surgical stabilisation to permit mobilisation the remaining 101 patients, treated conservatively were mobilised with immediate weight-bearing under the supervision of a physical therapist with assistive devices. Mean age was 73.5 years (SD 9.9 yrs). Fracture types were − 61.B2 47(37.6%), 61.B1 24(32%), 61.A2 17(13.6%), 61.C1 16(12.8%), 61.C2 5(4%), 61.A1 2(1.6%) and 61.C3 3(2.4%). Mechanisms of injury included fall from standing height − 41 (32%), road traffic collisions − 46(36.8%), fall from higher than standing height − 10(8%), fall from horse − 6(4.8%), jumped from bridge − 3(2.4%) & others 19(15%). Complications in surgical group included 1 death from PE and 1 wound infection treated with vacuum assisted dressing. Survivorship was 91.7%(30 days), 82.5%(1 year) and 49.7%(5 years). Most common fracture type is 61.B2. Over one third of fractures resulted from low energy mechanism. The majority 81% could be managed conservatively. One-year survival figure closely resembles the fracture neck of femur group, highlighting the frailty of this population

Aims

Disorders of bone integrity carry a high global disease burden, frequently requiring intervention, but there is a paucity of methods capable of noninvasive real-time assessment. Here we show that miniaturized handheld near-infrared spectroscopy (NIRS) scans, operated via a smartphone, can assess structural human bone properties in under three seconds.

In Alberta there are over 2,700 hip fractures per year costing the health system over $24 million in acute care costs alone. 50% of hip fracture patients have had a prior fragility fracture as a result of underlying osteoporosis (OP) that has never been assessed or appropriately treated. The Fracture Liaison Service (FLS) in Alberta aims to improve appropriate osteoporosis care, highlight and address gaps within seniors care through OP management, and provide a geriatric syndrome triage service. The FLS has developed a linkage with the Emergency Department (ED) geriatric team whereby hip fracture patients are identified in ED using a screening tool for geriatric syndromes prior to their surgery, allowing the FLS to follow through on comorbidities likely contributing to falls. An inpatient orthopaedic unit with a dedicated Registered Nurse (RN) and a Care of the Elderly Physician see and assess hip fracture patients after surgery for appropriate osteoporosis management and treatment. Screening tools have been developed to quickly detect underlying dementia and to quantify frailty to determine life expectancy and appropriate osteoporosis therapy. Patients are also referred to Geriatric Assessment Units and fall prevention programs. Patients are then contacted in the community at 3, 6,9,12 months by the FLS RN to follow up on osteoporosis therapy, and arrange other needed tests (i.e. bone mineral density, vitamin D) as needed. Information is sent to their family physician with all results. Prior to the patient's discharge from the FLS at one year, a final hand-over letter from the program will be provided outlining the plan of care for the patient. The FLS launched in June 2015 at the Misericordia hospital in Edmonton, Alberta (with plans to expand provincially). Currently 3 out of 4 hip fracture patients per week are being identified in the ED. Ninety-eight hip fracture patients have been identified post-surgery, with 71 patients eligible for enrollment in the program (five deceased patients). Sixty-six (50%) of those enrolled were discharged on osteoporosis medication compared to 8% prior to the program initiation. Seventeen (26%) of those were new medication starts. Of those not started, 7(11%) was patient choice. 11(31%) will be reassessed at 3 months for appropriate therapy. Nineteen (27%) of patients were referred to other inpatient or outpatient programs (i.e. falls, memory). Three month follow up calls have begun with patients for further data collection and a full 1 year qualitative and quantitative evaluation will be done. The implementation of an FLS with dedicated personnel to proactively manage and treat patients with appropriate investigations and interventions can close the care gap that exists in OP care. It also addresses gaps in senior care and provides appropriate referral to community geriatric programs, to improve quality of life and prevent future fractures

Listeria monocytogenes is usually thought of as a bacterial pathogen that causes invasive disease including meningitis and bacteraemia in susceptible hosts. It remains a rare cause of bone and joint infection; there is therefore potential for clinical and laboratory delay in diagnosis and for uncertainty over optimal management. We describe our experience of two such cases of L. monocytogenes prosthetic joint infection to highlight key features in clinical presentation and management. Two case reports of L. monocytogenes prosthetic joint infection are described with reference to previous published cases. A 57 year old woman presented with a 10 day history of severe pain and swelling around a left knee prosthesis which had been implanted as bilateral total knee replacements three years previously. She had a background of rheumatoid arthritis, controlled with prednisolone, methotrexate and ritixumab. Cultures from the left knee isolated L. monocytogenes. The patient was commenced on IV amoxicillin and after 4 weeks underwent 1st stage revision including radical debridement and removal of prosthesis. During the procedure an antibiotic-impregnated spacer (gentamycin/clindamycin with additional vancomycin added in house) was inserted. Antibiotic therapy with intravenous amoxicillin was continued for 2 weeks post-procedure and on discharge the patient was converted to oral amoxicillin for a further 8 weeks. The patient went on to have a 2nd stage revision, making a good recovery. An 85 year old woman presented with an 18 month history of discomfort and recurrent abscesses along the wound line of a left hip prosthesis, implanted over 20 years ago. She had a background of osteoarthritis and bullous phemphigoid, previously on steroid treatment. Fluid from the abscess was aspirated and isolated L. monocytogenes. Due to patient preference and frailty, radical revision was not thought a viable management option. Chronic suppressive therapy with oral amoxicillin was therefore instigated; one year on the infection remains well controlled and discomfort in the left hip has improved. L. monocytogenes has previously been infrequently implicated as a pathogen in prosthetic joint infection; however, there are reports of increasing numbers of cases particularly amongst immunosuppressed individuals. With an expanding at-risk population(1), its importance as a cause of prosthetic joint infection is set to rise in the future. Optimal management has not been well studied; it is likely that the best option combines antimicrobial therapy and prosthetic removal if possible

Aims

Despite the COVID-19 pandemic, incidence of hip fracture has not changed. Evidence has shown increased mortality rates associated with COVID-19 infection. However, little is known about the outcomes of COVID-19 negative patients in a pandemic environment. In addition, the impact of vitamin D levels on mortality in COVID-19 hip fracture patients has yet to be determined.

Aims

To evaluate safety outcomes and patient satisfaction of the re-introduction of elective orthopaedic surgery on ‘green’ (non-COVID-19) sites during the COVID-19 pandemic.
