Changes in circulating extracellular vesicle cargo are associated with cognitive decline after major surgery: an observational case-control study.

BACKGROUND: Postoperative neurocognitive decline is a frequent complication triggered by unclear signalling mechanisms. This observational case-control study investigated the effects of hip or knee replacement surgery on the composition of circulating extracellular vesicles (EVs), potential periphery-to-brain messengers, and their association with neurocognitive outcomes. METHODS: We mapped the microRNAome and proteome of plasma-derived EVs from 12 patients (six with good and six with poor neurocognitive outcomes at 3 months after surgery) at preoperative and postoperative timepoints (4, 8, 24, and 48 h). Complement C3-EV association was confirmed by flow cytometry in plasma- and cerebrospinal fluid (CSF)-derived EVs, with total plasma and CSF C3 and C3a concentrations determined using enzyme-linked immunosorbent assay. RESULTS: Differential expression analysis found eight dysregulated EV microRNAs (miRNAs) exclusively in the poor neurocognitive outcomes group. Pathway analysis suggested potential downregulation of proliferative pathways and activation of extracellular matrix and inflammatory response pathways in EV target tissues. Proteome analysis revealed a time-dependent increase in immune-related EV proteins, including complement system proteins, notably EV surface-associated C3. Such upward kinetics was detected earlier in the poor neurocognitive outcomes group. Interestingly, CSF-derived EVs from the same group showed a drastic drop of C3 at 48 h with unchanged concentrations in the good neurocognitive outcomes group. Functionally, the complement system was activated in both patient groups in plasma, but only in the poor neurocognitive outcomes group in CSF. CONCLUSIONS: Our findings highlight the impact of surgery on plasma- and CSF-derived EVs, particularly in patients with poor neurocognitive outcomes, indicating a potential role for EVs. The small sample size necessitates verification with a larger patient cohort.

From pain level to pain experience: redefining acute pain assessment to enhance understanding of chronic postsurgical pain.

BACKGROUND: Chronic postsurgical pain (CPSP) significantly impairs quality of life and poses a substantial healthcare burden, affecting up to a quarter of patients undergoing surgery. Although acute pain is recognised as a predictor for CPSP development, the role of patient experience remains underexplored. This study examines the predictive value of patient experience alongside traditional risk factors for CPSP after orthopaedic surgery. METHODS: An exploratory analysis was conducted on 294 patients from a multicentre randomised clinical trial comparing continuous perineural analgesia and single-injection nerve block in ambulatory orthopaedic surgeries. Patient experience was assessed using the Evaluation du Vecu de l'Anesthésie Générale (EVAN-G) validated questionnaire. Factors associated with CPSP at 90 days after surgery were identified through univariate and multivariate analyses, incorporating patient-reported outcomes and classical variables. RESULTS: Out of 219 patients with complete data, 63 (29%) developed CPSP at day 90. Multivariate analysis revealed a poor pain experience, as assessed by the pain dimension of EVAN-G on postoperative day 2, as an independent predictor of CPSP (odds ratio 6.45, 95% confidence interval 1.65-25.26, P<0.01). Poor pain experience was associated with an augmented risk of CPSP. CONCLUSIONS: This study underscores the role of patient-reported outcomes, specifically the pain experience dimension captured by the EVAN-G scale, in prediction of CPSP 90 days after surgery. It suggests a shift from conventional assessments of pain intensity to a comprehensive understanding of pain experience, advocating for tailored pain management approaches that could reduce chronic pain, thereby improving patient quality of life and functional recovery.

Hospital variation in quality indicators for patient blood management in total knee and hip arthroplasty: a retrospective cohort study.

BACKGROUND: Anaemia, blood loss, and blood transfusion are critical aspects of patient care in major orthopaedic surgery. We assessed hospital adherence to guideline-recommended Patient Blood Management (PBM) care, analysed variations between hospitals, and validated two composite indicators of hospital PBM performance in patients undergoing total knee arthroplasty (TKA) or total hip arthroplasty (THA). METHODS: This retrospective cohort study included all primary TKA and THA procedures performed during 2021 across 39 hospitals in Spain. We assessed hospital adherence to key guideline-recommended PBM interventions using nine individual quality indicators and two types of composite quality indicators (cQIs): opportunity-based (cQI1) and all-or-none (cQI2). We validated these cQIs by analysing their associations with the adjusted total transfusion index using linear regression. RESULTS: We included 8561 patient episodes from 33 hospitals in the analysis. Delivery of PBM care was similar for TKA and THA. Patients received 62% of the analysed PBM interventions and only 12% of patients underwent the full PBM pathway. Higher hospital cQIs scores were associated with a lower adjusted total transfusion index, both in TKA and THA. The greatest association was found for cQI1 in THA patients (ß=-1.18 [95% confidence interval -2.00 to -0.36]; P=0.007). CONCLUSIONS: Hospital adherence to guideline-recommended patient blood management care in total hip and knee arthroplasty was suboptimal and varied across centres. Using data that are widely available in hospitals, quality indicators and composite scores could become valuable tools for patient blood management monitoring and comparisons between healthcare organisations.

Associations between postoperative anaemia and unplanned readmission to hospital after major surgery: a retrospective cohort study†.

BACKGROUND: Anaemia following major surgery may be associated with unplanned readmission to hospital. However, the severity-response relationship between the degree of anaemia at discharge and the risk of unplanned readmission is poorly defined. We aimed to describe the severity-response relationship between haemoglobin concentration at the time of discharge and the risk of unplanned readmission in a cohort of patients undergoing different types of major surgery. METHODS: We performed a retrospective cohort study in a single tertiary health service, including all patients who underwent major surgery (orthopaedic, abdominal, cardiac or thoracic) between 1 May 2011 and 1 February 2022. The primary outcome was unplanned readmission to hospital in the 90 days following discharge after the index surgical procedure. These complex, non-linear relationships were modelled with restricted cubic splines. RESULTS: We identified 22,134 patients and included 14,635 in the primary analysis, of whom 1804 (12%) experienced at least one unplanned readmission. The odds of unplanned readmission rose when the discharge haemoglobin concentration was < 100 g.l-1 (p < 0.001). On subgroup analysis, the haemoglobin threshold below which odds of readmission began to increase appeared to be higher in patients undergoing emergency surgery (110 g.l-1; p < 0.001) compared with elective surgery. Declining discharge haemoglobin concentration was associated with increased odds ratios (95%CI) of unplanned readmission in patients undergoing orthopaedic (1.08 (1.01-1.15), p = 0.03), abdominal (1.13 (1.07-1.19), p < 0.001) and thoracic (1.12 (1.01-1.24), p = 0.03) procedures, but not cardiac surgery (1.09 (0.99-1.19), p = 0.07). CONCLUSIONS: Our findings suggest that a haemoglobin concentration < 100 g.l-1 following elective procedures and < 110 g.l-1 following emergency procedures, at the time of hospital discharge after major surgery, was associated with unplanned readmission. Future interventional trials that aim to treat postoperative anaemia and reduce unplanned readmission should include patients with discharge haemoglobin below these thresholds.

Prevention of thromboembolism after a fracture: is aspirin enough?

Venous thromboembolism (VTE) is a serious complication that can arise during and after hospitalization, particularly following surgery under general anaesthesia. Particularly at risk are major orthopaedic surgical procedures such as elective knee or hip replacement and the treatment of hip fractures. In these patients, current guidelines recommend (low or low-moderate level of evidence) aspirin as a possible alternative to anticoagulant therapy for the prophylaxis of long-term venous thromboembolism after an initial period with anticoagulant drugs. Several randomized trials and meta-analyses demonstrate no significant differences in the risk of VTE when comparing aspirin with anticoagulants. However, it must be considered that most recommendations are based on elective orthopaedic surgery and that trials after fractures have excluded patients at high thrombotic risk. Consequently, the overall incidence of major clinical events (death and pulmonary embolism) was ∼1% with wide confidence margins in even large non-inferiority studies. The incidence of asymptomatic VTE, especially distal, appears to be higher with aspirin. Patient preference and lower costs could play an important role in the choice in favour of aspirin.

Surgeon variation: a south african spinal pathology treatment survey.

PURPOSE: To investigate variation in treatment decisions among spine surgeons in South Africa and the association between surgeon characteristics and the treatment they select. METHODS: We surveyed 79 South African spine surgeons. We presented four vignettes (cervical spine distractive flexion injury, lumbar disc herniation, degenerative spondylolisthesis with stenosis, and insufficiency fracture) for them to assess and select treatments. We calculated the index of qualitative variation (IQV) to determine the degree of variability within each vignette. We used Fisher's exact, and Kruskal-Wallis tests to assess the relationships between surgeons' characteristics and their responses per vignette. We compared their responses to the recommendations of a panel of spine specialists. RESULTS: IQVs showed moderate to high variability for cervical spine distractive flexion injury and insufficiency fracture and slightly lower levels of variability for lumbar disc herniation and degenerative spondylolisthesis with stenosis. This confirms the heterogeneity in South African spine surgeons' management of spinal pathologies. The surgeon characteristics associated with their treatment selection that were important were caseload, experience and training, and external funding. Also, 19% of the surgeons selected a treatment option that the Panel did not support. CONCLUSION: The findings make a case for evaluating patient outcomes and costs to identify value-based care. Such research would help countries that are seeking to contract with providers on value. Greater uniformity in treatment and easily accessible outcomes reporting would provide guidance for patients. Further investment in training and participation in fellowship programs may be necessary, along with greater dissemination of information from the literature.

Outcomes of orthopaedic surgery in Ehlers-Danlos syndromes: a scoping review.

BACKGROUND: Patients with Ehlers-Danlos syndromes (EDS) often experience high rates of joint subluxations and dislocations, and associated pain that may require surgical interventions. Orthopaedic surgical management is challenging in this population, and patients will often undergo multiple unsuccessful surgeries. Outcomes data specific to patients with EDS are sparse in the orthopaedic surgery literature. We conducted a scoping review to evaluate the evidence and outcomes for orthopaedic surgery specifically for the EDS population. METHODS: PubMed MEDLINE, Embase, The Cochrane Library, Cochrane Controlled Register of Trials (CENTRAL), CINHL, and Scopus from their inception to February 28, 2024 for all studies that reported outcomes for orthopaedic surgery in patients with EDS. Two reviewers independently determined study eligibility, rated study quality, and extracted data. Methodology followed the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). The studies in this scoping review include Level III (retrospective cohort and case control) and Level IV (case series) evidence. RESULTS: The literature search yielded a total of 71 citations published between 1990 and 2023. All were primary studies. 38 were single case studies, 14 were case series, and 19 were retrospective cohort studies. No randomized clinical studies or systematic reviews were identified. Overall, the reported findings for the various anatomical sites and procedures indicated that surgery outcomes were inconsistent. Our review highlights the need for future research to determine whether currently established surgical approaches for various orthopaedic conditions offer long-term clinical benefit in patients with EDS. This is clearly a challenging diagnosis, and more rigorous clinical studies are required to identify optimal treatment approaches. CONCLUSIONS: Our review found little evidence-based research to guide optimal surgical treatment in EDS. Established surgical techniques that have been shown to be successful in the wider orthopaedic population should be studied to determine their efficacy in the EDS population.

Application of robot navigation system for insertion of femoral neck system in the treatment of femoral neck fracture.

PURPOSE: To evaluate the short-term clinical efficacy and advantages of surgery robot positioning system for insertion of Femoral Neck System (FNS) in the treatment of femoral neck fractures. METHODS: The clinical data of 52 patients with Femoral neck fracture (FNF) who had been treated with FNS between June 2020 and September 2021 were retrospectively analyzed. Among them, 26 patients were treated with traditional FNS (control group), while 26 additional patients were treated with FNS assisted by an orthopaedic robot positioning system (study group). The operation duration, frequency of key-guide needle placement, intraoperative blood loss, incision length, fracture healing rate, fracture healing time, and the Harris scores at the last follow-up were calculated and compared between the 2 groups. RESULTS: The study group had shorter operation duration, fewer numbers of placing the key-guide needle, less intraoperative blood loss, and smaller surgical incisions than the control group (all, P < 0.05). There was no significant difference in the rate of fracture healing rate between the 2 groups (P = 0.47), while the fracture healing duration of the study group was shorter than that of the control group (P = 0.03). At the last follow-up, compared with the control group, the Harris score and the number of excellent and good ratings were significantly higher in the study group (all, P < 0.05). CONCLUSIONS: Using orthopaedic surgery robot positioning system-assisted FNS in the treatment of FNFs can effectively improve the efficiency of surgery, shorten operation time, and reduce the number of placing the key-guide needle, intraoperative blood loss, and operative trauma. Simultaneously, it shortens the duration of fracture healing and improves the recovery of hip function.

Inertial measurement units to evaluate the efficacity of Equino Varus Foot surgery in post stroke hemiparetic patients: a feasibility study.

INTRODUCTION: This study evaluates the gait analysis obtained by Inetial Measurement Units (IMU) before and after surgical management of Spastic Equino Varus Foot (SEVF) in hemiplegic post-stroke patients and to compare it with the functional results obtained in a monocentric prospective cohort. METHODS: Patients with post-stroke SEVF, who underwent surgery in a single hospital between November 2019 and December 2021 were included. The follow-up duration was 6 months and included a functional analysis using Goal Attainment Scaling (GAS) and a Gait analysis using an innovative Multidimensional Gait Evaluation using IMU: the semiogram. RESULTS: 20 patients had a gait analysis preoperatively and at 6 months postoperatively. 90% (18/20) patients had a functional improvement (GAS T score ≥ 50) and 50% (10/20) had an improvement in walking technique as evidenced by the cessation of the use of a walking aid (WA). In patients with functional improvement and modification of WA the change in the semiogram area was + 9.5%, sd = 27.5%, and it was + 15.4%, sd = 28%. In the group with functional improvement without change of WA. For the 3 experiences (two patients) with unfavorable results, the area under the curve changed by + 2.3%, -10.2% and - 9.5%. The measurement of the semiogram area weighted by average speed demonstrated very good reproducibility (ICC(1, 3) = 0.80). DISCUSSION: IMUs appear to be a promising solution for the assessment of post-stroke hemiplegic patients who have undergone SEVF surgery. They can provide a quantified, objective, reliable in individual longitudinal follow up automated gait analysis solution for routine clinical use. Combined with a functional scale such as the GAS, they can provide a global analysis of the effect of surgery.

A practical guide to the development and deployment of deep learning models for the orthopaedic surgeon: Part III, focus on registry creation, diagnosis, and data privacy.

Deep learning is a subset of artificial intelligence (AI) with enormous potential to transform orthopaedic surgery. As has already become evident with the deployment of Large Language Models (LLMs) like ChatGPT (OpenAI Inc.), deep learning can rapidly enter clinical and surgical practices. As such, it is imperative that orthopaedic surgeons acquire a deeper understanding of the technical terminology, capabilities and limitations associated with deep learning models. The focus of this series thus far has been providing surgeons with an overview of the steps needed to implement a deep learning-based pipeline, emphasizing some of the important technical details for surgeons to understand as they encounter, evaluate or lead deep learning projects. However, this series would be remiss without providing practical examples of how deep learning models have begun to be deployed and highlighting the areas where the authors feel deep learning may have the most profound potential. While computer vision applications of deep learning were the focus of Parts I and II, due to the enormous impact that natural language processing (NLP) has had in recent months, NLP-based deep learning models are also discussed in this final part of the series. In this review, three applications that the authors believe can be impacted the most by deep learning but with which many surgeons may not be familiar are discussed: (1) registry construction, (2) diagnostic AI and (3) data privacy. Deep learning-based registry construction will be essential for the development of more impactful clinical applications, with diagnostic AI being one of those applications likely to augment clinical decision-making in the near future. As the applications of deep learning continue to grow, the protection of patient information will become increasingly essential; as such, applications of deep learning to enhance data privacy are likely to become more important than ever before. Level of Evidence: Level IV.

Orthopedic Surgery Volume Trends During the COVID-19 Pandemic and Postvaccination Era: Implications for Healthcare Planning.

BACKGROUND: The Coronavirus Disease 2019 (COVID-19) pandemic decreased surgical volumes, but prior studies have not investigated recovery through 2022, or analyzed specific procedures or cases of urgency within orthopedic surgery. The aims of this study were to (1) quantify the declines in orthopedic surgery volume during and after the pandemic peak, (2) characterize surgical volume recovery during the postvaccination period, and (3) characterize recovery in the 1-year postvaccine release period. METHODS: We conducted a retrospective cohort study of 27,476 orthopedic surgeries from January 2019 to December 2022 at one urban academic quaternary referral center. We reported trends over the following periods: baseline pre-COVID-19 period (1/6/2019 to 1/4/2020), COVID-19 peak (3/15/2020 to 5/16/2020), post-COVID-19 peak (5/17/2020 to 1/2/2021), postvaccine release (1/3/2021 to 1/1/2022), and 1-year postvaccine release (1/2/2022 to 12/30/2022). Comparisons were performed with 2 sample t-tests. RESULTS: Pre-COVID-19 surgical volume fell by 72% at the COVID-19 peak, especially impacting elective procedures (P < .001) and both hip and knee joint arthroplasty (P < .001) procedures. Nonurgent (P = .024) and urgent or emergency (P = .002) cases also significantly decreased. Postpeak recovery before the vaccine saw volumes rise to 92% of baseline, which further rose to 96% and 94% in 2021 and 2022, respectively. While elective procedures surpassed the baseline in 2022, nonurgent and urgent or emergency surgeries remained low. CONCLUSIONS: The COVID-19 pandemic substantially reduced orthopedic surgical volumes, which have still not fully recovered through 2022, particularly nonelective procedures. The differential recovery within an orthopedic surgery program may result in increased morbidity and can serve to inform department-level operational recovery.

Prior Bariatric Surgery Is Associated With Improved Total Hip Arthroplasty Outcomes in Patients Who Have Obesity: A National Cohort Study With 6 Years of Follow-Up.

BACKGROUND: Obesity is a risk factor for end-stage hip osteoarthritis. While total hip arthroplasty (THA) is commonly performed to reduce pain and improve function associated with osteoarthritis, obesity has been associated with an increased risk of complications after THA. Although bariatric surgery may also be utilized to reduce weight, the impact of bariatric surgery on THA outcomes remains inadequately understood. METHODS: This retrospective cohort analysis utilized multicenter electronic medical record data ranging from 2003 to 2023. Patients who have obesity who underwent THA were stratified based on prior bariatric surgery. The final bariatric cohort comprised 451 patients after propensity score matching. Complication rates and revision risks were compared between cohorts at 6, 24, and 72 months. Additional analysis stratified patients by interval between bariatric surgery and THA. RESULTS: At 6-month follow-up, the bariatric cohort had significantly lower risks of surgical site infection, wound dehiscence, and deep vein thrombosis (DVT). At 24 months, the bariatric cohort had a lower risk of DVT. At 72-month follow-up, the bariatric cohort had reduced rates of revision, mortality, cardiac morbidity, and Clavien-Dindo grade IV complications. CONCLUSIONS: Obese patients who underwent bariatric surgery prior to THA experienced reduced medical complications at all time points and reduced rates of revision at 72 months relative to a matched cohort who did not undergo bariatric surgery.

International Delphi Study on Wound Closure and Incision Management in Joint Arthroplasty Part 2: Total Hip Arthroplasty.

BACKGROUND: This modified Delphi study aimed to develop a consensus on optimal wound closure and incision management strategies for total hip arthroplasty (THA). Given the critical nature of wound care and incision management in influencing patient outcomes, this study sought to synthesize evidence-based best practices for wound care in THA procedures. METHODS: An international panel of 20 orthopedic surgeons from Europe, Canada, and the United States evaluated a targeted literature review of 18 statements (14 specific to THA and 4 related to both THA and total knee arthroplasty). There were 3 rounds of anonymous voting per topic using a modified 5-point Likert scale with a predetermined consensus threshold of ≥ 75% agreement necessary for a statement to be accepted. RESULTS: After 3 rounds of voting, consensus was achieved for all 18 statements. Notable recommendations for THA wound management included (1) the use of barbed sutures over non-barbed sutures (shorter closing times and overall cost savings); (2) the use of subcuticular sutures over skin staples (lower risk of superficial infections and higher patient preferences, but longer closing times); (3) the use of mesh-adhesives over silver-impregnated dressings (lower rate of wound complications); (4) for at-risk patients, the use of negative pressure wound therapy over other dressings (lower wound complications and reoperations, as well as fewer dressing changes); and (5) the use of triclosan-coated sutures (lower risk of surgical site infection) over standard sutures. CONCLUSIONS: Through a structured modified Delphi approach, a panel of 20 orthopedic surgeons reached consensus on all 18 statements pertaining to wound closure and incision management in THA. This study provides a foundational framework for establishing evidence-based best practices, aiming to reduce variability in patient outcomes and to enhance the overall quality of care in THA procedures.

Pressure injury risk factors in adult orthopaedic surgical patients: a cross-sectional study and random forest.

OBJECTIVE: To identify the most important risk factors for predicting pressure injury (PI) occurrence in adult orthopaedic surgical patients based on investigation data, thereby identifying at-risk patients and facilitating formulation of an effective patient care strategy. METHOD: Patients were assessed with an instrument designed by the authors specifically for this study in a cross-sectional investigation following the STROBE checklist. The random forest method was adopted to select the most important risk factors and predict occurrence of PIs. RESULTS: A dataset of 27 risk factors from 1701 patients was obtained. A subset of the 15 most important risk factors was identified. The random forest method had a high prediction accuracy of 0.9733 compared with 0.9281 calculated with a logistic model. CONCLUSION: Results indicated that the selected 15 risk factors, such as activity ability, friction/shear force, skin type and anaesthesia score, performed very well in predicting the occurrence of PIs in adult orthopaedic surgical patients.

Systematic review of nerves at risk at the wrist in common surgical approaches to the forearm: Anatomical variations and surgical implications.

Three commonly used approaches to the forearm in orthopedic surgery are Henry's, Thompson's, and the ulnar approach, each of which has the potential to cause injury to nerves around the wrist. Preserving these nerves is important to prevent complications such as neuroma formation and motor and sensory changes to the hand. We conducted a review of the literature to assess the nerves at risk and whether 'safe zones' exist to avoid these nerves. An independent reviewer conducted searches in Embase and MEDLINE of the literature from 2010 to 2020. A total of 68 papers were identified, with 18 articles being included in the review. Multiple nerves were identified as being at risk for each of the approaches described. In the anterior approach, the palmar cutaneous branch of the median nerve (PCBMN) is most at risk of injury. An incision immediately radial to the flexor carpi radialis (FCR) or directly over the FCR is most likely to avoid injury to both superficial branch of the radial nerve (SBRN) and PCBMN. With Thompson's approach, the safest zone for an incision is directly over or slightly radial to Lister's tubercle to avoid injury to SBRN and lateral cutaneous nerve of the forearm. For the ulnar approach, a safe zone was shown to be on the ulnar side of the wrist around the ulnar styloid (US) when the forearm was in supination or a neutral position to avoid injury to the dorsal branch of the ulna nerve (DBUN). Care must be taken around the US due to the density of nerves and the proximity of the last motor branch of the posterior interosseous nerve to the ulnar head. This review highlighted the proximity of nerves to the three most common surgical incisions used to access the forearm. In addition, anatomical variations may exist, and each of the nerves identified as being at risk has multiple branches. Both factors increase the potential of intraoperative damage if the anatomy is not properly understood. The surgeon must adhere carefully to the established approaches to the wrist and distal forearm to minimize damage to nerves and optimize surgical outcomes for the patient.

The Predictive Effect of the Level of Psychological Resilience on the Level of Readiness for Discharge in Patients Undergoing Orthopaedic Surgery.

AIM: The aim of this study is to establish the correlation between the degree of psychological resilience and readiness for discharge in patients undergoing orthopaedic surgery. DESIGN: This study is of a descriptive correlational type. MATERIAL AND METHOD: This study comprised a cohort of 190 patients who were admitted to the orthopaedics and traumatology department and had surgical procedures performed between November 2023 and April 2024. The study data were gathered via completion of the Introductory Information Form, the Psychological Resilience Scale and the Hospital Discharge Readiness Scale. IBM SPSS 25 package program was used to analyse the research data. RESULTS: In this study, 34.2% of the participants stated that they did not feel ready for discharge. Predictors of Readiness for Hospital Discharge were identified as being male (ß = 0.118, p = 0.003), living alone (ß = 0.222, p < 0.001), having undergone prosthesis, fracture or amputation surgery (ß = 0.161, p < 0.001), not having received discharge training (ß = 0.122, p = 0.001), not feeling ready for discharge (ß = 0.442, p < 0.001) and resilience (ß = 0.246, p < 0.001). These variables were found to explain 88.7% of Readiness for Hospital Discharge (adjusted R2 = 0.773). CONCLUSION: The findings of this study emphasise that including patients in their healthcare and creating comprehensive discharge plans tailored to their specific care requirements have a beneficial impact on their readiness for discharge. Additionally, the study demonstrates that enhancing psychological resilience plays a mediating role in facilitating discharge readiness. IMPLICATIONS FOR THE PATIENT CARE: Patients who feel ready for discharge are less likely to be hospitalised and their recovery may be faster. Including the patient in the discharge plan, taking individual needs into consideration and disseminating programmes to increase resilience should be an integral part of holistic care. REPORTING METHOD: The STROBE checklist was applied in the reporting of the finding.

Standing on shoulder of giants: the incredible legacy of the Judet family in orthopaedic surgery.

In orthopaedic surgery, as well as other areas in medicine, it is common for a surgical technique to carry the original authors' name describing the procedure. The Judet family represents a unique history, since several orthopaedic procedures are known as "Judet's technique". The aim of this historic review is to outline the genealogy of the orthopaedic arm of the Judet family, while crediting each surgical procedure to the specific family member that described the technique.

Assessment of stress level and depression among orthopaedic surgeons in Saudi Arabia.

PURPOSE: The aim of this study was to assess the stress level and depression among orthopaedic surgeons in Saudi Arabia. In addition, to evaluate orthopedic training programs related factors that might have a critical role in the development of depression among orthopaedic surgeons. METHODS: The study adopted a cross-sectional study design. Two validated questionnaires were utilized, the Patient Health Questionnaire 9 (PHQ-9) and the Perceived Stress Scale (PSS-10) for assessing depressive symptoms and stress levels. Data was collected by sending the survey to the Saudi Commission for Health Specialties so they could be distributed throughout all registered orthopaedic surgeons. RESULTS: The study sample consisted of 325 participants. The results revealed that the severity of depression varied across the different groups. As per the PHQ-9 criteria, 74 (22.8%) were initially diagnosed with major depression. Among assistant consultants, 39.5% reported severe depression, while 34.9% reported mild depression. Consultants predominantly reported moderate perceived stress (82.9%) with a notable proportion experiencing high perceived stress (12.4%). Assistant consultants showed a balanced distribution, with 93.0% reporting moderate perceived stress and 4.7% reporting high perceived stress. Demographic variables gender, relationship status and having children revealed statistically significant relationship with PHQ-9 scores (p-value < 0.05) but not with PSS-10 scores. CONCLUSION: The study highlights pressing need to address mental health concerns within orthopaedic surgeons. To address these challenges, healthcare institutions should implement comprehensive mental health support programs offering resources for stress management, counseling services, and peer support groups.

Efficacy and safety of 4-hydroxy-2-methyl-N-(5-methyl-2-thiazolyl)-2H-1, 2-benzothiazin-3-carboxamide 1,1-dioxide, a rapid-acting meloxicam formulation, for analgesia after orthopaedic surgery under general anaesthesia: a randomized controlled trial.

BACKGROUND: Postoperative pain management is one of the most challenging treatments after orthopaedic surgery, and improved medical treatment options are urgently needed. This study aimed to evaluate the efficacy and safety of 4-hydroxy-2-methyl-N-(5-methyl-2-thiazolyl)-2H-1, 2-benzothiazin-3-carboxamide 1,1-dioxide (QP001) for moderate to severe pain following orthopaedic surgery. METHODS: This randomized clinical trial enlisted patients experiencing moderate to severe pain following orthopaedic surgery in 20 hospitals in China. We allocated randomly 132 participants to receive 30 mg QP001 and 66 participants to receive 0.9% saline pre-surgery. The primary efficacy outcome was the total morphine consumption within 24 h. RESULTS: The total morphine consumption in the QP001 group, versus placebo group, was significantly lower over the following 24 h [12.53 (10.51) vs. 26.13 (13.98), P < 0.001]. The total morphine consumption in the QP001 group, versus placebo group, was also significantly decreased over the following 48 h (P < 0.001). The QP001 group, versus placebo, showed a significant decrease in the effective pressing times of the analgesic pump, morphine relief analgesia ratio over the 24 h and 48 h periods and the area under the curve for pain intensity-time as well as a significant prolonged in the time of first pressing the analgesic pump and the time of first morphine rescue analgesia (P < 0.001). The QP001 groups, versus placebo, show no significant difference in adverse events, but the incidence of adverse drug reactions decreased (59.4% vs. 75.8%, P = 0.023). CONCLUSION: QP001 provides analgesia and reduces opioid consumption in patients with moderate to severe pain after orthopaedic surgery, with a favorable safety profile.

Attitude of aspiring orthopaedic surgeons towards artificial intelligence: a multinational cross-sectional survey study.

INTRODUCTION: The purpose of this study was to evaluate the perspectives of aspiring orthopaedic surgeons on artificial intelligence (AI), analysing how gender, AI knowledge, and technical inclination influence views on AI. Additionally, the extent to which recent AI advancements sway career decisions was assessed. MATERIALS AND METHODS: A digital survey was distributed to student members of orthopaedic societies across Germany, Switzerland, and Austria. Subgroup analyses explored how gender, AI knowledge, and technical inclination shape attitudes towards AI. RESULTS: Of 174 total respondents, 86.2% (n = 150) intended to pursue a career in orthopaedic surgery and were included in the analysis. The majority (74.5%) reported 'basic' or 'no' knowledge about AI. Approximately 29.3% believed AI would significantly impact orthopaedics within 5 years, with another 35.3% projecting 5-10 years. AI was predominantly seen as an assistive tool (77.8%), without significant fear of job displacement. The most valued AI applications were identified as preoperative implant planning (85.3%), administrative tasks (84%), and image analysis (81.3%). Concerns arose regarding skill atrophy due to overreliance (69.3%), liability (68%), and diminished patient interaction (56%). The majority maintained a 'neutral' view on AI (53%), though 32.9% were 'enthusiastic'. A stronger focus on AI in medical education was requested by 81.9%. Most participants (72.8%) felt recent AI advancements did not alter their career decisions towards or away from the orthopaedic specialty. Statistical analysis revealed a significant association between AI literacy (p = 0.015) and technical inclination (p = 0.003). AI literacy did not increase significantly during medical education (p = 0.091). CONCLUSIONS: Future orthopaedic surgeons exhibit a favourable outlook on AI, foreseeing its significant influence in the near future. AI literacy remains relatively low and showed no improvement during medical school. There is notable demand for improved AI-related education. The choice of orthopaedics as a specialty appears to be robust against the sway of recent AI advancements. LEVEL OF EVIDENCE: Cross-sectional survey study; level IV.
