Aims. The purpose of this study was to evaluate the cost of reverse shoulder arthroplasty (RSA) for patients with a proximal humerus fracture, using time-driven activity based costing (TDABC), and to compare treatment costs with reimbursement under the Healthcare Resource Groups (HRGs). Methods. TDABC analysis based on the principles outlined by Kaplan and a clinical pathway that has previously been validated for this institution was used. Staffing cost, consumables, implants, and overheads were updated to reflect 2019/2020 costs. This was compared with the HRG reimbursements. Results. The mean cost of a RSA is £7,007.46 (£6,130.67 to £8,824.67). Implants and staffing costs were the primary cost drivers, with implants (£2,824.80) making up 40% of the costs. Staffing costs made up £1,367.78 (19%) of overall costs. The total tariff, accounting for market force factors and high comorbidities, reimburses £4,629. If maximum cost and minimum reimbursement is applied the losses to the trust are £4,828.67. Conclusion. RSA may be an effective and appropriate surgical option in the treatment of proximal humerus fractures; however, a cost analysis at our centre has demonstrated the financial burden of this surgery. Given its increasing use in trauma, there is a need to work towards generating an HRG that adequately reimburses providers. Cite this article: Bone Jt Open 2020;1-12:731–736

Aims

Infective complications following implant related orthopaedic surgery or fracture related infection are associated with high costs and increased length of stay (LOS). However, the economic burden of disease before, during and after definitive osteomyelitis surgery is not well quantified. The Hospital Episode Statistics (HES) database captures all admissions, outpatient appointments and emergency department attendances at NHS hospitals in England. We identified all patients with a diagnostic code of osteomyelitis and quantified the tariff costs associated with the surgical treatment of osteomyelitis. We also collected all recorded healthcare events related to osteomyelitis for two years preceding the initial osteomyelitis treatment procedure, as well as for two years after the procedure. We compared average osteomyelitis treatment costs in England against a dedicated specialist multidisciplinary bone infection centre.

Methods

We interrogated the HES database for all patients given a diagnostic code of osteomyelitis (M86) between April 2013 and January 2017. We excluded all cases with a diagnosis of osteomyelitis and an index procedure of an amputation for diabetes or arterial disease. Of the remaining 104,622 patients there were 24,408 cases who had their index procedure for osteomyelitis in this time period. Of these we compared a subset of 575 cases treated in a specialist bone infection centre.

BACKGROUND

Theatre-listed trauma patients routinely require two ‘group and save’ blood-bank samples, in case they need perioperative transfusion. The Welsh Blood Service (WBS) need patients to have one recorded sample from any time in the last 10 years. A second sample, to permit cross-matching and blood issuing, must be within 7 days of transfusion (or within 48 hours if the patient is pregnant, or has been transfused within the last 3 months). The approximate cost of processing a sample is £15.00.

AIM

To investigate whether routine pretransfusion blood sampling for trauma admissions exceeds requirements.

Introduction

The number of revision hip arthroplasty procedures is rising annually with 7852 such operations performed in the UK in 2010. These are expensive procedures due to pre-operative investigation, surgical implants and instrumentation, protracted hospital stay, and pharmacological costs. There is a paucity of robust literature on the costs associated with the common indications for this surgery.

Objective

We aim to quantify the cost of revision hip arthroplasty by indication and identify any short-fall in relation to the national tariff.

Aims. The burden of revision total hip arthroplasty (rTHA) continues to grow. The surgery is complex and associated with significant costs. Regional rTHA networks have been proposed to improve outcomes and to reduce re-revisions, and therefore costs. The aim of this study was to accurately quantify the cost and reimbursement for a rTHA service, and to assess the financial impact of case complexity at a tertiary referral centre within the NHS. Methods. A retrospective analysis of all revision hip procedures was performed at this centre over two consecutive financial years (2018 to 2020). Cases were classified according to the Revision Hip Complexity Classification (RHCC) and whether they were infected or non-infected. Patients with an American Society of Anesthesiologists (ASA) grade ≥ III or BMI ≥ 40 kg/m. 2. are considered “high risk” by the RHCC. Costs were calculated using the Patient Level Information and Costing System (PLICS), and remuneration based on Healthcare Resource Groups (HRG) data. The primary outcome was the financial difference between tariff and cost per patient episode. Results. In all, 199 revision episodes were identified in 168 patients: 25 (13%) least complex revisions (H1); 110 (55%) complex revisions (H2); and 64 (32%) most complex revisions (H3). Of the 199, 76 cases (38%) were due to infection, and 78 patients (39%) were “high risk”. Median length of stay increased significantly with case complexity from four days to six to eight days (p = 0.006) and for revisions performed for infection (9 days vs 5 days; p < 0.001). Cost per episode increased significantly between complexity groups (p < 0.001) and for infected revisions (p < 0.001). All groups demonstrated a mean deficit but this significantly increased with revision complexity (£97, £1,050, and £2,887 per case; p = 0.006) and for infected failure (£2,629 vs £635; p = 0.032). The total deficit to the NHS Trust over two years was £512,202. Conclusion. Current NHS reimbursement for rTHA is inadequate and should be more closely aligned to complexity. An increase in the most complex rTHAs at major revision centres will likely place a greater financial burden on these units. Cite this article: Bone Jt Open 2023;4(8):559–566

Purpose: To meet the increasing demand for arthroplasty in Canada healthcare providers are investigating efficiency improvements to maximize utilization of limited surgical resources. One target is routine annual arthroplasty follow-up for which there are no established guidelines. A previous study by the authors revealed that 52% of arthroplasty patients could be followed with standardized questionnaires and x-rays resulting in a 30% savings to the healthcare system. In this study we report the patient time, travel and financial burdens for annual follow-up at a tertiary care centre versus a hypothetical model using standardized assessment at community hospitals and a web-enabled PACS. Method: A consecutive sample survey of elective THA and TKA patients (n=158; 99 females; 94 THA; 64 TKA; mean age=69 years) who were at least twelve months postoperative. Patient’s address, work status, mode of travel and times required for travel, physician consult, x-ray, and clinic wait were recorded. A web-based mapping application was used to determine distances from patients’ homes to the tertiary care centre and nearest community hospital. Financial burden was calculated using Statistics Canada figures for average Canadian wage and private vehicle travel costs. Results: Sixteen patients were working at the time of the study and 149 travelled in a private vehicle. For the tertiary care centre: round-trip distance was 168 km, total time burden was 194 minutes (travel=129 minutes, clinic wait=54 minutes, time with physician=6 minutes, x-ray=5 minutes), and total financial burden per patient was $58. For the community hospital: round-trip distance was 19 km, total time burden was 39 minutes (travel=14 minutes, clinic wait=20 minutes, x-ray=5 minutes), and total financial burden was $7. Conclusion: Utilizing community hospital resources for arthroplasty follow-up could reduce patients’ travel by 89%, financial burden by 88%, and time burden by 81%. This approach has the potential to enable the focusing of arthroplasty clinic follow-up resources only on patients reporting problems or with symptomatic x-rays thus freeing up surgeon time for surgeries. There are also the broader societal implications of reducing ‘health miles’ and the resulting carbon dioxide emissions related to health care delivery by leveraging new technologies to move information rather than people

Aim. The number of periprosthetic joint infections (PJI) is increasing due to ageing population and increasing numbers of arthroplasty procedures and treatment is costly. Aim of the study was to analyze the direct healthcare costs of PJI in Europe for total hip arthroplasties (THA) and total knee arthroplasties (TKA). Method. A systematic review in PubMed with search of direct costs of PJI in European countries was performed. Thereby the term cost* AND (infection OR PJI) AND (prosthesis OR knee OR hip OR “TKA” OR “THA” OR arthroplast*) was combined with each European country to detect relevant publications. Publications with definition of performed procedure and joint localization were included into further analysis. The mean value of direct healthcare cost was calculated for the respective joint and the respective operation performed. Results. Screening revealed 1,274 eligible publications. After review of abstracts and full-texts n=11 manuscripts were included into final analysis (Figure 1). The mean combined direct hospital costs for revision for PJI after TKA and THA was 26,311€. Mean costs for revision procedures for PJI after TKA were 24,617€. Direct costs for TKA-PJI treated with debridement, antibiotics and implant retention (DAIR) were on average 10,121€. For two-stage revisions in knee arthroplasties total average costs were 30,829€. Referring to revision surgery for PJI in THA, the mean hospital costs in Europe were 28,005€. For a DAIR procedure direct healthcare costs of 5,528€ were identified. Two-stage revision cost on average 31,217€. Conclusions. PJIs are associated with significant direct healthcare costs. The financial burden of up to 30,000 € per case underlines the impact of the disease for European health care system. However, the number of detailed reports on PJI costs is limited and the quality of the literature is limited. There is a strong need for more detailed financial data on the costs of PJI treatment.

Advances in total hip and knee replacement technologies have heretofore been largely driven by corporate marketing hype with each seeming advancement accompanied by a cost increase often out in front of peer-reviewed reports documenting their efficacy or not. As example, consider the growing use of ceramic femoral heads in primary total hip arthroplasty (THA). The question to consider is “Can an upcharge of $350 for a ceramic femoral head in primary THA be justified?” The answer to this question lies in an appreciation of whether the technology modifies the potential for costly revision arthroplasty procedures. Peer-Reviewed Laboratory & Clinical Review - According to the 2022 Australian National Joint Replacement Registry, the four leading causes of primary THA failure requiring revision are: 1.) infection, 2.) dislocation/instability, 3.) periprosthetic fracture and 4.) loosening, which constitute 87.5% of the reported reasons for revision. Focusing on these failure modes, hip simulator findings report that ceramic femoral heads dramatically reduce wear debris generation, decreasing the potential for osteolytic response leading to loosening. Further, ceramic materials enable the utilization of larger head sizes, avoiding the potential for dislocation. The overall mid- to long-term survival rate reported in the peer-reviewed, clinical literature for these bearings has exceeded 95% with virtually no osteolysis. Also, could bearing surface choice influence periprosthetic joint infection (PJI)? A study on a total of more than 10,500 primary THA procedures reported a confirmed PJI incidence of 2.4% for cobalt-chrome and 1.6% for ceramic femoral heads, suggesting that the employ of a ceramic bearing surface may also play a role in decreasing the potential for infection. Review of the clinical data available for ceramic bearings justifies that it is better to “pay me now than to pay orders of magnitude later”, if in fact a revision THA can be avoided, significantly reducing the overall financial burden to the healthcare system

Introduction. Knee arthroplasty (KA), encompassing Total Knee Replacement (TKR) and Unicompartmental Knee Replacement (UKR), is one of the most common orthopedic procedures, aimed at alleviating severe knee arthritis. Postoperative KA management, especially radiographic imaging, remains a substantial financial burden and lacks standardised protocols for its clinical utility during follow-up. Method. In this retrospective multicentre cohort study, data were analysed from January 2014 to March 2020 for adult patients undergoing primary KA at Imperial NHS Trust. Patients were followed over a five-year period. Four machine learning models were developed to evaluate if post-operative X-ray frequency can predict revision surgery. The best-performing model was used to assess the risk of revision surgery associated with different number of X-rays. Result. The study assessed 289 knees with a 2.4% revision rate. The revision group had more X-rays on average than the primary group. The best performing model was Logistic Regression (LR), which indicated that each additional X-ray raised the revision risk by 52% (p<0.001). Notably, having four or more X-rays was linked to a three-fold increase in risk of revision (OR=3.02; p<0.001). Our results align with the literature that immediate post-operative X-rays have limited utility, making the 2nd post-operative X-ray of highest importance in understanding the patient's trajectory. These insights can enhance management by improving risk stratification for patients at higher revision surgery risk. Despite LR being the best-performing model, it is limited by the dataset's significant class imbalance. Conclusion. X-ray frequency can independently predict revision surgery. This study provides insights that can guide surgeons in evidence-based post-operative decision-making. To use those findings and influence post-operative management, future studies should build on this predictive model by incorporating a more robust dataset, surgical indications, and X-ray findings. This will allow early identification of high-risk patients, allowing for personalised post-operative recommendations

Introduction. The knee is the most commonly injured joint in sporting accidents, leading to substantial disability, time off work and morbidity (1). Treatment and assessment vary around the UK (2), whilst there remains a limited number of high-quality randomised controlled trials assessing first time, acute soft tissue knee injuries (3,4). As the clinical and financial burden rises (5), vital answers are required to improve prevention, diagnosis, treatment, rehabilitation, and delivery of care. In association with the James Lind Alliance, this BASK, BOSTAA and BOA supported prioritising exercise was undertaken over a year. Methods. The James Lind Alliance methodology was followed; a modified nominal group technique was used in the final workshop. An initial survey invited patients and healthcare professionals to submit their uncertainties regarding soft tissue knee injury prevention, diagnosis, treatment, rehabilitation, and delivery of care. Seventy-four questions were formulated to encompass common concerns. These were checked against best available evidence. Following the interim survey, 27 questions were taken forward to the final workshop in January 2023, where they were discussed, ranked, and scored in multiple rounds of prioritisation by groups of healthcare professionals, patients, and carers. Results. Over 1000 questions were submitted initially. Twenty-seven were taken forward to the final workshop following the surveys. Nearly half of the responses were from patients/carers. The Top 10 (Figure 1) includes prevention, diagnosis, treatment, and rehabilitation questions, reflecting the concerns of patients, carers, and a wider multidisciplinary team. Conclusion. This validated process has generated an important, wide- ranging Top 10 priorities for future soft tissue knee injury research. These have been submitted to the National Institute for Health and Care Research and are now available for researchers to investigate. The final 27 questions which were taken to the final workshop have also been published on the James Lind Alliance website. Research into these questions will lead to future high-quality research, thus improving patient care & outcomes. For any figures or tables, please contact authors directly

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. Methods. 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. Results. Eight retrospective studies involving 29,738 patients with IBD were included. Compared with non-IBD controls, patients with IBD were significantly more likely to have overall complications (OR 2.11 (95% CI 1.67 to 2.66), p < 0.001), medical complications (OR 2.15 (95% CI 1.73 to 2.68), p < 0.001), surgical complications (OR 1.43 (95% CI 1.21 to 1.70), p < 0.001), and 90-day readmissions (OR 1.42 (95% CI 1.23 to 1.65), p < 0.001). The presence of IBD was positively associated with the development of venous thromboembolism (OR 1.60 (95% CI 1.30 to 1.97), p < 0.001) and postoperative infection (OR 1.95 (95% CI 1.51 to 2.51), p < 0.001). In addition, patients with IBD tended to experience longer LOS and higher costs of care. Conclusion. The findings suggest that IBD is associated with an increased risk of postoperative complications and readmission after joint arthroplasty, resulting in longer hospital stay and greater financial burden. Surgeons should inform their patients of the possibility of adverse outcomes prior to surgery and make appropriate risk adjustments to minimize potential complications.

Introduction. Non-union is an unfortunate outcome of the fracture healing process for some patients; with an estimated annual incidence of 17.4- 18.9 per 100,00. The management of these patients depicts a significant clinical challenge for surgeons and financial burden to health services. External ultrasound stimulation devices (Exogen. TM. ) have been highlighted as a novel non invasive therapy to achieve union in cases of delayed and non-union. The aim of the current study was to assess the rate of union in patients using Exogen. TM. therapy for delayed fracture union in a district general hospital. Materials & Methods. This is a single centre retrospective continuous cohort study. Patients were identified from a prospective database of all patients prescribed Exogen. TM. therapy between June 2013- September 2021 in a district general hospital. Patient data was collected retrospectively using electronic patient records. Fracture union was assessed both clinically and radiographically and recorded in patient records. Failure of treatment was defined as progression to operative treatment due to lack of progression with ultrasound therapy or established asymptomatic non-union. Patient were excluded from the study if Exogen. TM. therapy was prescribed within 6 weeks of injury. Results. 142 potential patient were identified from the database. 35 patients were excluded from the data set (17 patients due to insufficient data available, 9 lost to follow up, 4 died and 5 excluded due to early application of Exogen. TM. therapy). 58 Patients progressed to union with an average time to union of 41 weeks. 49 cases failed to progress to union, of which 7 cases had conversion to operative management prior to completion of single course of Exogen. TM. therapy and were excluded from all other data review. 12% of cases that failed to unite with ultrasound therapy required multiple operations to establish union. Conclusions. A union rate of 58% was reported by the current study, which is lower than previously published. This likely reflects the heterogenous nature of the patient population and fracture distribution included. However, this is potentially a more reflective union rate for the general population than previously published. There were no adverse events associated with the use of Exogen. TM. therapy in the current study. Therefore supporting its use as a first line management to promote union in delayed fracture union in the general population. Additionally, failure to achieve fracture union with utilisation of Exogen. TM. therapy was associated with risk for requirement of multiple surgeries to achieve union. This could serve as an indicator for surgeon to consider the requirement additional measures at the initial surgical procedure

Aims. Advances in surgical technique and implant design may influence the incidence and mechanism of failure resulting in revision total hip arthroplasty (rTHA). The purpose of the current study was to characterize aetiologies requiring rTHA, and to determine whether temporal changes existed in these aetiologies over a ten-year period. Methods. All rTHAs performed at a single institution from 2009 to 2019 were identified. Demographic information and mode of implant failure was obtained for all patients. Data for rTHA were stratified into two time periods to assess for temporal changes: 2009 to 2013, and 2014 to 2019. Operative reports, radiological imaging, and current procedural terminology (CPT) codes were cross-checked to ensure the accurate classification of revision aetiology for each patient. Results. In all, 2,924 patients with a mean age of 64.6 years (17 to 96) were identified. There were 1,563 (53.5%) female patients, and the majority of patients were Caucasian (n = 2,362, 80.8%). The three most frequent rTHA aetiologies were infection (27.2%), aseptic loosening (25.2%), and wear (15.2%). The frequency of rTHA for adverse local tissue reaction (ALTR) was significantly greater from 2014 to 2019 (4.7% vs 10.0%; p < 0.001), while the frequency of aseptic loosening was significantly greater from 2009 to 2013 (28.6% vs 21.9%; p < 0.001). Conclusion. Periprosthetic joint infection was the most common cause for rTHA in the current cohort of patients. Complications associated with ALTR necessitating rTHA was more frequent between 2014 to 2019, while aseptic loosening necessitating rTHA was significantly more frequent between 2009 to 2013. Optimizing protocols for prevention and management of infection and ALTR after THA may help to avoid additional financial burden to institutions and healthcare systems.

Revision total hip arthroplasty (rTHA) can be complex and associated with significant cost, with an increasing burden within the UK and globally. Regional rTHA networks have been proposed aiming to improve outcomes, reduce re-revisions and therefore costs. The aim of this study was to accurately quantify the cost and reimbursement for the rTHA service and to assess the financial impact of case complexity at a tertiary referral centre within the NHS. A retrospective analysis of all revision hip procedures was performed over two consecutive financial years (2018–2020). Cases were classified according to the Revision Hip Complexity Classification (RHCC) and by mode of failure; infected or non-infected. Patients of ASA grade of 3 or greater or BMI over 40 are considered “high-risk” by the RHCC. Costs were calculated using PLICS and remuneration based on the HRG data. The primary outcome was the financial difference between tariff and cost per episode per patient. Comparisons between groups were analysed using analysis of variance and two-tailed unpaired t-test. 199 revision episodes were identified in 168 patients: 25 (13%) least complex revisions (H1), 110 (55%) complex revisions (H2) and 64 (32%) most complex revisions (H3). 76 (38%) cases were due to infection. 78 (39%) of patients were in the “high-risk” group. Median length of stay increased with case complexity from 4, to 6 to 8 days (p=0.17) and significantly for revisions performed for infection (9 vs 5 days; p=0.01). Cost per episode increased significantly between complexity groups (p=0.0002) and for infected revisions (p=0.003). All groups demonstrated a mean deficit, but this significantly increased with revision complexity (£301, £1,820 and £4,757 per case; p=0.02) and for infected failure (£4,023 vs £1,679; p=0.02). The total deficit to the trust for the two-years was £512,202. Current NHS reimbursement for rTHA is inadequate and should be more closely aligned to complexity. An increase in the most complex rTHA at major revision centres (MRC) will likely place a greater financial burden on these units

Background:. Injuries inflicted by gunshot wounds (GSW) are an immense financial burden on the South African healthcare system. The cost of treating an abdominal GSW has previously been estimated at R30 000 per patient. No study has been conducted to estimate the financial burden from an orthopaedic perspective. Objective:. To estimate the average cost of treating GSW victims requiring orthopedic interventions in a South African tertiary level hospital. Methods:. The study surveyed over 1,500 orthopedic admissions to our institution during 2012 to indentify GSW patients. A folder review yielded data on theatre time, implant cost, duration of admission, diagnostic-imaging studies performed, blood products used, laboratory costs and medicines issued to analyze costs. Results:. A total of 111 patients with an average age of 28 years (range 13–74) were identified. Each patient was hit by an average of 1.69 bullets (range 1–7). One hundred and forty seven fractures were sustained. Ninety-five patients received surgical treatment for a total of 128 orthopedic procedures, 15 concurrent general/vascular surgery procedures, and a cumulative surgical time of 198 hours 42 minutes. Cumulative anaesthetic time was 277 hours 33 minutes. Theatre costs (excluding implants) were estimated to be in excess of ten million rands. Ninety three of the patients received an implant during surgery which raised theatre costs even more. Total costs were in excess of R130 000.00 forward admissions, R180 000.00 for imaging, R190 000.00 for blood products, R16 000.00 for laboratory investigations and R16 000.00 for discharge medication. Conclusion:. Using varying calculations it was estimated that on average an orthopaedic GSW patient costs about R100 000.00 to treat, utilises about 2 hours of theatre time per operation and occupies a bed for an average period of 9 days

Aims. The primary aim is to estimate the current and potential number of patients on NHS England orthopaedic elective waiting lists by November 2020. The secondary aims are to model recovery strategies; review the deficit of hip and knee arthroplasty from National Joint Registry (NJR) data; and assess the cost of returning to pre-COVID-19 waiting list numbers. Methods. A model of referral, waiting list, and eventual surgery was created and calibrated using historical data from NHS England (April 2017 to March 2020) and was used to investigate the possible consequences of unmet demand resulting from fewer patients entering the treatment pathway and recovery strategies. NJR data were used to estimate the deficit of hip and knee arthroplasty by August 2020 and NHS tariff costs were used to calculate the financial burden. Results. By November 2020, the elective waiting list in England is predicted to be between 885,286 and 1,028,733. If reduced hospital capacity is factored into the model, returning to full capacity by November, the waiting list could be as large as 1.4 million. With a 30% increase in productivity, it would take 20 months if there was no hidden burden of unreferred patients, and 48 months if there was a hidden burden, to return to pre-COVID-19 waiting list numbers. By August 2020, the estimated deficits of hip and knee arthroplasties from NJR data were 18,298 (44.8%) and 16,567 (38.6%), respectively, compared to the same time period in 2019. The cost to clear this black log would be £198,811,335. Conclusion. There will be up to 1.4 million patients on elective orthopaedic waiting lists in England by November 2020, approximate three-times the pre-COVID-19 average. There are various strategies for recovery to return to pre-COVID-19 waiting list numbers reliant on increasing capacity, but these have substantial cost implications.

Abstract. Objectives. Up to 19% of patients who undergo surgery for an acute hip fracture are readmitted to the hospital within three months of the index operation. We aimed to identify risk factors for unplanned clinic attendance, readmission, and mortality within the first 12 months postoperatively and subsequently determine if there is a role for routine follow-up. Methods. Patients greater than 65 years old who underwent hip hemiarthroplasty using an uncemented Thompson implant for treatment of a traumatic non-pathological hip fracture were identified from a prospectively maintained database at a single institution between August 2007 and February 2011. Patient demographics, comorbidities, place of residence, mobility status, unplanned attendance to an orthopaedic clinic with symptoms relating to the respective limb, readmission, and mortality were recorded. Results. Five hundred and fifty-four consecutive patients were identified. Unplanned clinic attendance was correlated to age (p = 0.000, B = −0.0159, 95% confidence interval (CI): −0.200 to −0.65), with patients between the ages of 65 – 70 years most likely to require unplanned clinic review postoperatively. The American Society of Anesthesiologists (ASA) grade (p = 0.019, 95% CI: 0.014 to 0.163) and frequency of unplanned outpatient attendance (p = 0.000, 95% CI: 0.120 to 0.284) were significantly associated with increased readmission within 12 months of the index procedure with patients who were regarded as ASA > 2 most likely to require readmission within the first postoperative year. Conclusion. To our knowledge, this is the first piece of research that identifies causative factors for unplanned clinic attendance and acute readmission during the first postoperative year in acute hip fracture patients treated by hemiarthroplasty. Routine scheduled follow-up of patients based on risk stratification may be effective in reducing the financial burden of unplanned clinic attendance. Declaration of Interest.

Introduction and Objective. Hip fractures represent one of the most challenging injuries in orthopaedic practice due to the associated morbidity, mortality and the financial burden they impose on the health care systems. By many still considered as the gold standard in the management of intertrochanteric fractures, the Dynamic Hip Screw utilizes controlled collapse during weight bearing to stabilize the fracture. Despite being a highly successful device, mechanical failure rate is not uncommon. The most accepted intraoperative indicator for lag screw failure is the tip apex distance (TAD), yet lateral femoral wall thickness (LWT) is another evolving parameter for detecting the potential for lateral wall fracture with subsequent medialization and implant failure. The aim of this study is to determine the mean and cut off levels for LWT that warrant lateral wall fracture and the implications of that on implant failure, revision rates and implant choice. Materials and Methods. This prospective cohort study included 42 patients with a mean age of 70.43y with intertrochanteric hip fractures treated with DHS fixation by the same consultant surgeon from April 2019 to December 2019. The study sample was calculated based on a confidence level of 90% and margin of error of 5%. Fracture types included in the study are 31A1 and 31A2 based on the AO/OTA classification system. LWT was assessed in all patients preoperatively using Surgimap (Nemaris, NY, USA) software. Patients were divided into two groups according to the post-operative integrity of the lateral femoral wall, where group (A) sustained a lateral femoral wall fracture intraoperatively or within 12 months after the index procedure, while in group (B) the lateral femoral wall remained intact. All patients were regularly followed up radiologically and clinically per the Harris Hip Score (HHS) for a period of 12 months. Results. At 12 months five patients (12%) suffered a postoperative lateral wall fracture, while in 37 patients (88%) the lateral femoral wall remained intact. The mean preoperative LWT of patients with a postoperative lateral wall fracture was 18.04 mm (SD ± 1.58) compared to 26.22mm (SD ± 5.93) in the group without a lateral wall fracture. All patients with post-operative lateral femoral wall fracture belong to 31A2 group, while 78.4% of the patients that did not develop post-operative lateral femoral wall fracture belong to 31A1 group. Eighty percent of patients in group (A) experienced shortening, collapse, shaft medialization and varus deformity. The mean Harris hip score of group (A) was 39.60 at 3 months and 65.67 at 6 months postoperatively, while that of group (B) was 80.75 and 90.65 at 3 and 6 months respectively, denoting a statistically significant difference (P<0.001). Treatment failure meriting a revision surgery was 40 % in group (A) and 8% in group (B) denoting a statistically significant difference (p<0.001). The cut-off point of LWT below which there is a high chance of post-operative lateral wall fracture when fixed with DHS is 19.6mm. This was shown on the receiver operating curve (ROC) by plotting the sensitivity against the 100 % specificity with a set 95% confidence interval 0.721 – 0.954. When lateral wall thickness was at 19.6 mm, the sensitivity was 100% and specificity was 81.8%. The area under the curve (AUC) was 0.838, which was statistically significant (P = 0.015). Conclusions. Preoperative measurement of LWT in elderly patients with intertrochanteric hip fractures is decisive. The cut off point for postoperative lateral wall fracture according to our study is 19.6 mm; hence, intramedullary fixation has to be considered in this situation

Acute pain is one of the most common symptoms shared among patients who have suffered from an orthopedic trauma such as an isolated upper limb fracture (IULF). Development of interventions with limited side effects aiming to prevent the installation of chronic pain is critical as persistent pain is associated with an increased risk of opioid dependence, medical complications, staggering financial burdens and diminished quality of life. Theta burst stimulation (TBS), a non-invasive magnetic brain stimulation technique with minimal side effects, has shown promising results in patients experiencing various types of chronic pain conditions as it precisely targets brain regions involved in pain processing. Surprisingly, its impact on acute pain has never been investigated. This study aims to assess longitudinal effects of a 10-day continuous TBS (cTBS) protocol applied in the acute phase of an IULF on key functional outcomes. Patients with an IULF aged between 18 to 60 years old were recruited within 7 days post-accident at a Level I Trauma Center. Exclusion criteria included a history of brain injury, neurological disorders, musculoskeletal complications, and open fractures. In order to assess longitudinal changes, questionnaires measuring intensity and characteristics of pain (Numerical Rating Scale, NRS; McGill Pain Questionnaire, MPQ) as well as functional disability (DASH) were completed by all patients at three time points, namely prior to the start of the TBS program as well as 72 hours and 3 months post-intervention. Patients were randomly attributed to the active TBS protocol (active group) or to the placebo protocol (sham group). The stimulation site for each participant corresponded to the contralateral motor cortex of the injured arm. Fifty patients were recruited (female: 24; age: 40.38 years old), of which 25 were in the active group and 25 were in the sham group. Both groups were equivalent based on age, sex, type of injury, and surgical procedures (p>0.05). The intervention protocol was introduced on average 6.18 days post-accident. In comparison to the sham group, the active group showed a significant decrease in pain intensity (NRS) at 72h (F=6.02; p=0.02) and 3-month (F=6.37; p=0.02) post-intervention. No group difference was found early-on (72h post) in regard to pain characteristics (MPQ; F=3.90; p=0.06) and functional disabilities (DASH; F=0.48; p= 0.49). At three-month post-intervention, the active group showed statistically significant improvement on the MPQ (F=5.02; p=0.04) and the DASH (F=5.88; p=0.02) compared to the placebo group. No complications related to the treatment were reported. Results from this study show that patients who underwent active cTBS reported less pain and better functional states shortly after the end of the TBS protocol compared to sham patients and treatment effects were maintained at three months post-intervention. Given that acute pain intensity is an excellent predictor of chronic pain development, this safe technique available in numerous centers in Canada may help prevent chronic pain development when administered during the acute post-injury phase. Future studies should continue to investigate mechanisms involved to optimize this technique among the orthopedic trauma population and to reduce opioid consumption


Surgical site infections (SSIs) are associated with significant consequences in orthopaedic surgery, where their presence can lead to ultimate revision of the implant. Furthermore, infections and impaired wound healing can prolong length of hospital stay following orthopaedic surgery, which can place additional financial burdens on healthcare systems. The current analysis was conducted to determine whether the use of the PICO single-use negative pressure wound therapy (sNPWT) system after orthopaedic surgery reduced the incidence of SSIs and length of hospital stay compared with using conventional dressings. A systematic literature review (SLR) was performed using the PubMed, Embase and Cochrane Library databases. English-language studies comparing PICO sNPWT to conventional dressings published from 2011 to August 2018 with ≥10 patients in each treatment arm were included. Reference lists of included studies were searched for further relevant studies. Meta-analyses were performed using a fixed effect (I. 2. < 50%) or random effects model (I. 2. ≥ 50%). The SLR identified 6,197 studies, of which 5 relevant studies (607 patients) were included. The odds of an SSI were reduced by 57% (odds ratio [OR]: 0.43; 95% confidence interval [CI]: 0.21–0.86; p = 0.02) and there was consistency between studies (I. 2. = 0%). Three studies reported on length of hospital stay. The mean difference between patient groups indicated that PICO sNPWT was associated with a 1-day reduction in hospital stay (mean difference [MD]: −0.99; 95% CI: −1.32 to −0.65; p < 0.00001) and there was again consistency between studies (I. 2. = 0%). These results suggest that the use of PICO sNPWT system after closed surgical incisions can reduce the incidence of SSIs and shorten the duration of hospital stay when used in orthopaedic patient populations
