Spinal Anesthesia or General Anesthesia for Hip Surgery in Older Adults.

BACKGROUND: The effects of spinal anesthesia as compared with general anesthesia on the ability to walk in older adults undergoing surgery for hip fracture have not been well studied. METHODS: We conducted a pragmatic, randomized superiority trial to evaluate spinal anesthesia as compared with general anesthesia in previously ambulatory patients 50 years of age or older who were undergoing surgery for hip fracture at 46 U.S. and Canadian hospitals. Patients were randomly assigned in a 1:1 ratio to receive spinal or general anesthesia. The primary outcome was a composite of death or an inability to walk approximately 10 ft (3 m) independently or with a walker or cane at 60 days after randomization. Secondary outcomes included death within 60 days, delirium, time to discharge, and ambulation at 60 days. RESULTS: A total of 1600 patients were enrolled; 795 were assigned to receive spinal anesthesia and 805 to receive general anesthesia. The mean age was 78 years, and 67.0% of the patients were women. A total of 666 patients (83.8%) assigned to spinal anesthesia and 769 patients (95.5%) assigned to general anesthesia received their assigned anesthesia. Among patients in the modified intention-to-treat population for whom data were available, the composite primary outcome occurred in 132 of 712 patients (18.5%) in the spinal anesthesia group and 132 of 733 (18.0%) in the general anesthesia group (relative risk, 1.03; 95% confidence interval [CI], 0.84 to 1.27; P = 0.83). An inability to walk independently at 60 days was reported in 104 of 684 patients (15.2%) and 101 of 702 patients (14.4%), respectively (relative risk, 1.06; 95% CI, 0.82 to 1.36), and death within 60 days occurred in 30 of 768 (3.9%) and 32 of 784 (4.1%), respectively (relative risk, 0.97; 95% CI, 0.59 to 1.57). Delirium occurred in 130 of 633 patients (20.5%) in the spinal anesthesia group and in 124 of 629 (19.7%) in the general anesthesia group (relative risk, 1.04; 95% CI, 0.84 to 1.30). CONCLUSIONS: Spinal anesthesia for hip-fracture surgery in older adults was not superior to general anesthesia with respect to survival and recovery of ambulation at 60 days. The incidence of postoperative delirium was similar with the two types of anesthesia. (Funded by the Patient-Centered Outcomes Research Institute; REGAIN ClinicalTrials.gov number, NCT02507505.).

Long-term Outcomes with Spinal versus General Anesthesia for Hip Fracture Surgery: A Randomized Trial.

BACKGROUND: The effects of spinal versus general anesthesia on long-term outcomes have not been well studied. This study tested the hypothesis that spinal anesthesia is associated with better long-term survival and functional recovery than general anesthesia. METHODS: A prespecified analysis was conducted of long-term outcomes of a completed randomized superiority trial that compared spinal anesthesia versus general anesthesia for hip fracture repair. Participants included previously ambulatory patients 50 yr of age or older at 46 U.S. and Canadian hospitals. Patients were randomized 1:1 to spinal or general anesthesia, stratified by sex, fracture type, and study site. Outcome assessors and investigators involved in the data analysis were masked to the treatment arm. Outcomes included survival at up to 365 days after randomization (primary); recovery of ambulation among 365-day survivors; and composite endpoints for death or new inability to ambulate and death or new nursing home residence at 365 days. Patients were included in the analysis as randomized. RESULTS: A total of 1,600 patients were enrolled between February 12, 2016, and February 18, 2021; 795 were assigned to spinal anesthesia, and 805 were assigned to general anesthesia. Among 1,599 patients who underwent surgery, vital status information at or beyond the final study interview (conducted at approximately 365 days after randomization) was available for 1,427 (89.2%). Survival did not differ by treatment arm; at 365 days after randomization, there were 98 deaths in patients assigned to spinal anesthesia versus 92 deaths in patients assigned to general anesthesia (hazard ratio, 1.08; 95% CI, 0.81 to 1.44, P = 0.59). Recovery of ambulation among patients who survived a year did not differ by type of anesthesia (adjusted odds ratio for spinal vs. general, 0.87; 95% CI, 0.67 to 1.14; P = 0.31). Other outcomes did not differ by treatment arm. CONCLUSIONS: Long-term outcomes were similar with spinal versus general anesthesia.

A quasi-experimental evaluation of the association between implementation of Quality-Based Procedures funding for hip fractures and improvements in processes and outcomes for hip fracture patients in Ontario: an interrupted time series analysis.

PURPOSE: In 2013, Ontario introduced a patient-based funding model for hip fracture care (Quality-Based Procedures [QBP]). The association of QBP implementation with changes in processes and outcomes has not been evaluated. METHODS: We conducted a quasi-experimental study using linked health data for adult hip fractures as an interrupted time series. The pre-QBP period was from 2008 to 2012 and the post-QBP period was from 2014 to 2018; 2013 was excluded as a wash-in period. We used segmented regression analyses to estimate the association of QBP implementation with changes in processes (surgery in less than two days from admission, use of echocardiography, use of nerve blocks, and provision of geriatric care) and clinical outcomes (90-day mortality, 90-day readmissions, length of stay, and days alive at home). We estimated the immediate (level) change, trend (slope) postimplementation, and total counterfactual differences. Sensitivity analyses included case-mix adjustment and stratification by hospital type and procedure. RESULTS: We identified 45,500 patients in the pre-QBP period and 41,256 patients in the post-QBP period. There was a significant total counterfactual increase in the use of nerve blocks (11.1%; 95% confidence interval [CI], 6.2 to 16.0) and a decrease in the use of echocardiography (-2.5%; 95% CI, -3.7 to -1.3) after QBP implementation. The implementation of QBP was not associated with a clinically or statistically meaningful change in 90-day mortality, 90-day readmission, length of stay, or number of days alive at home. CONCLUSION: Evaluation of the QBP program is crucial to inform ongoing and future changes to policy and funding for hip fracture care. The introduction of the QBP Hip Fracture program, supported by evidence-based recommendations, was associated with improved application of some evidence-based processes of care but no changes in clinical outcomes. There is a need for ongoing development and evaluation of funding models to identify optimal strategies to improve the value and outcomes of hip fracture care.

RéSUMé: OBJECTIF: En 2013, l'Ontario a mis en place un modèle de financement axé sur les patient·es pour les soins suivant une fracture de la hanche (procédures fondées sur la qualité [PFQ]). L'association entre la mise en œuvre des PFQ et les changements dans les processus et les devenirs n'a pas été évaluée. MéTHODE: Nous avons mené une étude quasi expérimentale en utilisant des données de santé couplées pour les fractures de la hanche chez l'adulte comme une série chronologique interrompue. La période précédant les PFQ s'étendait de 2008 à 2012, et la période subséquente à l'implantation des PFQ allait de 2014 à 2018. L'année 2013 a été exclue en tant que période de rodage. Nous avons utilisé des analyses de régression segmentées pour estimer l'association entre la mise en œuvre des PFQ avec des changements aux processus (chirurgie en moins que deux jours suivant l'admission, utilisation de l'échocardiographie, utilisation de blocs nerveux et prestation de soins gériatriques) et des issues cliniques (mortalité à 90 jours, réadmissions à 90 jours, durée de séjour et jours de vie à domicile). Nous avons estimé le changement immédiat (niveau), la tendance (pente) après la mise en œuvre et les différences contrefactuelles totales. Les analyses de sensibilité comprenaient l'ajustement et la stratification de la combinaison de cas par type d'hôpital et par procédure. RéSULTATS: Nous avons identifié 45 500 patient·es dans la période pré-PFQ et 41 256 patient·es dans la période post-PFQ. Il y a eu une augmentation contrefactuelle totale significative de l'utilisation de blocs nerveux (11,1 %; intervalle de confiance [IC] à 95 %, 6,2 à 16,0) et une diminution de l'utilisation de l'échocardiographie (−2,5 %; IC 95 %, −3,7 à −1,3) après la mise en œuvre des PFQ. La mise en œuvre des PFQ n'a pas été associée à un changement cliniquement ou statistiquement significatif de la mortalité à 90 jours, de la réadmission à 90 jours, de la durée de séjour ou du nombre de jours de vie à domicile. CONCLUSION: L'évaluation du programme de PFQ est cruciale pour guider les changements actuels et futurs aux politiques et au financement des soins suivant une fracture de la hanche. La mise en place du programme de PFQ pour les fractures de la hanche, appuyée par des recommandations fondées sur des données probantes, a été associée à une meilleure application de certains processus de soins fondés sur des données probantes, mais à aucun changement dans les devenirs cliniques. Il est nécessaire d'élaborer et d'évaluer continuellement des modèles de financement afin de déterminer les stratégies optimales pour améliorer la valeur et les devenirs des soins suivant une fracture de la hanche.

National Institute of Health and Care Excellence Guidelines for Displaced Intracapsular Hip Fractures: Examining Satisfaction With the Guidelines and Effects on Outcomes.

BACKGROUND: The objectives of the study were to: (1) evaluate satisfaction with the new 2023 National Institute of Health and Care Excellence (NICE) criteria for selecting total hip arthroplasty (THA) over hemiarthroplasty and surgical recommendations for treatment of displaced intracapsular hip fractures; (2) describe why THA is performed when NICE criteria are not met; and (3) determine whether satisfaction with these guidelines is associated with improved outcomes. METHODS: A retrospective chart review of patients who had a displaced intracapsular hip fracture treated with THA at a single tertiary academic center between 2010 and 2022 was performed. Preoperative patient characteristics were reviewed to determine if the indication for THA met NICE criteria. Operative details, perioperative complications, reoperation, and revision arthroplasty within 12 months of surgery were recorded. RESULTS: Data from 196 patients (63% women; age 67 ± 10 years) were used. There were 161 THAs (82.1%) that satisfied NICE criteria. The 2 most common reasons for performing a THA when NICE criteria were not met (n = 35) included preoperative radiographic osteoarthritis (Tönnis grade ≥ 2; 48.6%) and decreased patient age (< 65 years; 31.5%). Satisfaction with the NICE criteria was associated with fewer perioperative complications (0.6 versus 37.1%; P < .001), reoperations (0.6 versus 31.4%; P < .001), and revisions (0.6 versus 28.6%; P < .001). The most common reason for revision was periprosthetic fracture, possibly secondary to the use of uncemented femoral stems (171 of 196, 87.2%). CONCLUSIONS: Satisfaction with the new NICE criteria is associated with improved perioperative outcomes. Further studies are necessary to determine if preexisting hip osteoarthritis and younger age merit consideration in patient selection.

Pain, Analgesic Use, and Patient Satisfaction With Spinal Versus General Anesthesia for Hip Fracture Surgery : A Randomized Clinical Trial.

BACKGROUND: The REGAIN (Regional versus General Anesthesia for Promoting Independence after Hip Fracture) trial found similar ambulation and survival at 60 days with spinal versus general anesthesia for hip fracture surgery. Trial outcomes evaluating pain, prescription analgesic use, and patient satisfaction have not yet been reported. OBJECTIVE: To compare pain, analgesic use, and satisfaction after hip fracture surgery with spinal versus general anesthesia. DESIGN: Preplanned secondary analysis of a pragmatic randomized trial. (ClinicalTrials.gov: NCT02507505). SETTING: 46 U.S. and Canadian hospitals. PARTICIPANTS: Patients aged 50 years or older undergoing hip fracture surgery. INTERVENTION: Spinal or general anesthesia. MEASUREMENTS: Pain on postoperative days 1 through 3; 60-, 180-, and 365-day pain and prescription analgesic use; and satisfaction with care. RESULTS: A total of 1600 patients were enrolled. The average age was 78 years, and 77% were women. A total of 73.5% (1050 of 1428) of patients reported severe pain during the first 24 hours after surgery. Worst pain over the first 24 hours after surgery was greater with spinal anesthesia (rated from 0 [no pain] to 10 [worst pain imaginable]; mean difference, 0.40 [95% CI, 0.12 to 0.68]). Pain did not differ across groups at other time points. Prescription analgesic use at 60 days occurred in 25% (141 of 563) and 18.8% (108 of 574) of patients assigned to spinal and general anesthesia, respectively (relative risk, 1.33 [CI, 1.06 to 1.65]). Satisfaction was similar across groups. LIMITATION: Missing outcome data and multiple outcomes assessed. CONCLUSION: Severe pain is common after hip fracture. Spinal anesthesia was associated with more pain in the first 24 hours after surgery and more prescription analgesic use at 60 days compared with general anesthesia.

Outcomes with spinal versus general anesthesia for patients with and without preoperative cognitive impairment: Secondary analysis of a randomized clinical trial.

INTRODUCTION: The effect of spinal versus general anesthesia on the risk of postoperative delirium or other outcomes for patients with or without cognitive impairment (including dementia) is unknown. METHODS: Post hoc secondary analysis of a multicenter pragmatic trial comparing spinal versus general anesthesia for adults aged 50 years or older undergoing hip fracture surgery. RESULTS: Among patients randomized to spinal versus general anesthesia, new or worsened delirium occurred in 100/295 (33.9%) versus 107/283 (37.8%; odds ratio [OR] 0.85; 95% confidence interval [CI] 0.60 to 1.19) among persons with cognitive impairment and 70/432 (16.2%) versus 71/445 (16.0%) among persons without cognitive impairment (OR 1.02; 95% CI 0.71 to 1.47, p = 0.46 for interaction). Delirium severity, in-hospital complications, and 60-day functional recovery did not differ by anesthesia type in patients with or without cognitive impairment. DISCUSSION: Anesthesia type is not associated with differences in delirium and functional outcomes among persons with or without cognitive impairment.

Delayed mobilization following admission for hip fracture is associated with increased morbidity and length of hospital stay.

BACKGROUND: Current national guidelines on caring for hip fractures recommend early mobilization. However, this recommendation does not account for time spent immobilized waiting for surgery. We sought to determine timing of mobilization following hip fracture, beginning at hospital admission, and evaluate its association with medical complications and length of hospital stay (LOS). METHODS: We performed a retrospective review of prospectively collected data for 470 consecutive patients who underwent surgery for a hip fracture between September 2019 and August 2020 at an academic, tertiary-referral hospital. Outcomes of interest included time from hospital admission to mobilization, complication rate and LOS. We used a binary regression analysis to determine the effect of different surgical and patient factors on the risk of a postoperative medical complication. RESULTS: The mean time from admission to mobilization was 2.8 ± 2.3 days (range 3 h-14 d). There were 125 (26.6%) patients who experienced at least 1 complication. The odds of developing a complication began to increase steadily once a patient waited more than 3 days from admission to mobilization (odds ratio 2.15, 95% confidence interval 1.42-3.25). Multivariate regression analysis showed that prefracture frailty (ß = 0.276, p = 0.05), and timing from hospital admission to mobilization (ß = 0.156, p < 0.001) and from surgery to mobilization (ß = 1.195, p < 0.001) were associated with complications. The mean LOS was 12.2 ± 10.7 days (range 1-90 d). Prolonged wait to mobilization was associated with longer LOS (p = 0.01). CONCLUSION: Comprehensive guidelines on timing of mobilization following hip fracture should account for cumulative time spent immobilized.

Optimal entry point for antegrade and retrograde femoral intramedullary nails.

Surgical management of femoral shaft fractures with intramedullary nails has become the standard of care, with multiple options for entry point described, including piriformis entry, trochanter entry and retrograde femoral nails. Our present review describes the surgical anatomy of the proximal and distal femur and its relation to different entry points for intramedullary femoral nails. In addition, we reviewed relative indications for each technique, difficulties associated and possible complications.

Instability after hip hemiarthroplasty for femoral neck fracture: an unresolved problem.

BACKGROUND: The dislocated hip hemiarthroplasty (HA) remains a difficult condition to treat owing to frailty, comorbidity, poor quality of bone and soft tissues. We aimed to identify parameters contributing to instability following hip HA and describe the operative management and patient outcomes. METHODS: We retrospectively reviewed consecutive cases of all patients with hip fracture treated between 2004 and 2019 at a single tertiary care institution. We propensity matched patients with and without hip dislocations on a 1:2 basis for age, sex, and approach. We reviewed risk factors for HA dislocation, performed radiographic measurements, and recorded management of dislocation and further complications. RESULTS: Of the 1472 patients treated with HA, we included 18 patients (1.2%) who sustained at least 1 dislocation in our analysis. Of the dislocations identified, 13 and 17 occurred within 1 and 3 months postoperative, respectively. The presence of dementia and low preoperative lateral centre-edge angle were associated with increased risk of dislocation. The 2-year mortality rate was significantly higher in the dislocation group (n = 9) than the control group (n = 2) (p = 0.0003). Nine of 18 (50%) patients were treated with an initial closed reduction; 5 of these 9 (56%) sustained further dislocations and required additional treatment. Six of 18 cases were treated with a total hip arthroplasty after their first dislocation. By final follow-up, 2 of 18 patients had Girdlestone procedures. CONCLUSION: This study highlights patient factors associated with increased dislocation risk following hip HA. A thorough preoperative assessment is indicated when presented with dislocated HA to prevent further complications.

Urinary catheter use in patients with hip fracture: Are current guidelines appropriate? A retrospective review.

BACKGROUND: Guidelines for urinary catheterization in patients with hip fracture recommend limiting catheter use and using intermittent catheterization preferentially to avoid complications such as urinary tract infection (UTI) and postoperative urinary retention (POUR). We aimed to compare current practices to clinical guidelines, describe the incidence of POUR and UTI, and determine factors that increase the risk of these complications. METHODS: We retrospectively reviewed the charts of patients with hip fracture who presented to a single large tertiary care centre in southeastern Ontario between November 2015 and October 2017. Data collected included comorbidities, catheter use and length of stay. We compared catheter use to guidelines, and investigated the incidence of and risk factors for POUR and UTI. RESULTS: We reviewed the charts of 583 patients, of whom 450 (77.2%) were treated with a catheter, primarily indwelling (416 [92.4%]). Postoperative urinary retention developed in 98 patients (16.8%); however, it did not affect length of stay (p = 0.2). Patients with indwelling catheters for more than 24 hours after surgery had a higher incidence of POUR than those who had their catheter removed before 24 hours (65/330 [19.7%] v. 10/98 [10.2%]) (odds ratio [OR] 2.2, 95% confidence interval [CI] 1.06-4.38). A UTI developed postoperatively in 62 patients (10.6%). Catheter use was associated with a 6.6-fold increased risk of UTI (OR 6.6, 95% CI 2.03-21.4). Patients with indwelling catheters did not have a significantly higher incidence of UTI than those with intermittent catheterization (57/416 [13.7%] v. 2/34 [5.9%]) (p = 0.2). Patients who developed a UTI had significantly longer catheter use than patients who did not (p < 0.002). CONCLUSION: Indwelling catheters were used frequently, which suggests low compliance with clinical guidelines. Longer duration of catheter use led to higher rates of UTI and POUR. Further investigation of the reasons for the common use of indwelling rather than intermittent catheterization is needed.

Preventing hip fractures with multidisciplinary teams: a Canadian perspective.

Fragility fractures (FFs) are low-energy trauma fractures that occur at or below standing height. Among FFs, hip fractures are associated with the greatest morbidity, mortality and cost to Canadian health care systems. This review highlights the current state of medical care for hip fractures in Canada, with specific focus on the role of the multidisciplinary team. Gaps in care exist, as FFs represent a unique challenge requiring both acute and chronic management. Furthermore, there is a lack of ownership of FFs by a medical specialty. These gaps can be addressed through the use of multidisciplinary teams, which have been shown to be efficacious and cost-effective. This model of care also addresses numerous patient-identified barriers to treatment, including inadequate patient counselling. However, there is still room for improvement in both the identification of patients at risk for hip fracture and patient adherence to therapy.

Les fractures de fragilisation (FF) sont des fractures qui surviennent lors d'un traumatisme léger se produisant depuis la position debout ou d'une hauteur moindre. Les fractures de la hanche sont les FF associées aux plus grands taux de morbidité et de mortalité et aux plus grands coûts pour les systèmes de santé au Canada. La présente revue s'intéresse à l'état actuel des soins médicaux pour une fracture de la hanche au pays et porte une attention spéciale au rôle de l'équipe multidisciplinaire. Des lacunes dans les soins existent et sont mises en évidence par les FF, qui posent un défi bien particulier en nécessitant une prise en charge à la fois aiguë et chronique. De plus, cette prise en charge ne relève d'aucune spécialité médicale. La correction de ces lacunes peut passer par le recours aux équipes multidisciplinaires, dont l'efficacité et la rentabilité ont été démontrées. Ce modèle de soins élimine également de nombreux obstacles au traitement signalés par les patients, y compris le counseling inadéquat. Des améliorations sont néanmoins encore nécessaires dans l'identification des patients à risque de fracture de la hanche et dans l'observance du traitement.

Impact of disuse muscular atrophy on the compound muscle action potential.

BACKGROUND: Disuse atrophy from immobilization is the result of decreased neural activity and muscle unloading. METHODS: We studied the impact of disuse on hand intrinsic compound muscle action potentials (CMAPs) in a cohort of 39 patients with unilateral 6-week immobilization of the hand in a cast, after distal radius fracture. We excluded patients with nerve injury. We compared side-to-side CMAP characteristics at the time of cast removal and at a subsequent follow-up visit, after a mean interval of 7.8 weeks. RESULTS: Statistically significant reductions in CMAP amplitude were noted for the abductor pollicis brevis (29.2%), abductor digiti minimi (19.0%), and first dorsal interosseus (24.9%). There was partial repair of the relative CMAP reduction at the follow-up visit (20.1%, 10.7%, and 8.7%, respectively). There was no significant change in CMAP duration. CONCLUSIONS: These results provide a framework for quantifying the degree of hand intrinsic CMAP amplitude reduction attributed to disuse.

A Trial of Wound Irrigation in the Initial Management of Open Fracture Wounds.

BACKGROUND: The management of open fractures requires wound irrigation and débridement to remove contaminants, but the effectiveness of various pressures and solutions for irrigation remains controversial. We investigated the effects of castile soap versus normal saline irrigation delivered by means of high, low, or very low irrigation pressure. METHODS: In this study with a 2-by-3 factorial design, conducted at 41 clinical centers, we randomly assigned patients who had an open fracture of an extremity to undergo irrigation with one of three irrigation pressures (high pressure [>20 psi], low pressure [5 to 10 psi], or very low pressure [1 to 2 psi]) and one of two irrigation solutions (castile soap or normal saline). The primary end point was reoperation within 12 months after the index surgery for promotion of wound or bone healing or treatment of a wound infection. RESULTS: A total of 2551 patients underwent randomization, of whom 2447 were deemed eligible and included in the final analyses. Reoperation occurred in 109 of 826 patients (13.2%) in the high-pressure group, 103 of 809 (12.7%) in the low-pressure group, and 111 of 812 (13.7%) in the very-low-pressure group. Hazard ratios for the three pairwise comparisons were as follows: for low versus high pressure, 0.92 (95% confidence interval [CI], 0.70 to 1.20; P=0.53), for high versus very low pressure, 1.02 (95% CI, 0.78 to 1.33; P=0.89), and for low versus very low pressure, 0.93 (95% CI, 0.71 to 1.23; P=0.62). Reoperation occurred in 182 of 1229 patients (14.8%) in the soap group and in 141 of 1218 (11.6%) in the saline group (hazard ratio, 1.32, 95% CI, 1.06 to 1.66; P=0.01). CONCLUSIONS: The rates of reoperation were similar regardless of irrigation pressure, a finding that indicates that very low pressure is an acceptable, low-cost alternative for the irrigation of open fractures. The reoperation rate was higher in the soap group than in the saline group. (Funded by the Canadian Institutes of Health Research and others; FLOW ClinicalTrials.gov number, NCT00788398.).

Understanding and Taking Control of Surgical Learning Curves.

As surgical techniques continue to evolve, surgeons will have to integrate new skills into their practice. A learning curve is associated with the integration of any new procedure; therefore, it is important for surgeons who are incorporating a new technique into their practice to understand what the reported learning curve might mean for them and their patients. A learning curve should not be perceived as negative because it can indicate progress; however, surgeons need to understand how to optimize the learning curve to ensure progress with minimal patient risk. It is essential for surgeons who are implementing new procedures or skills to define potential learning curves, examine how a reported learning curve may relate to an individual surgeon's in-practice learning and performance, and suggest methods in which an individual surgeon can modify his or her specific learning curve in order to optimize surgical outcomes and patient safety. A defined personal learning contract may be a practical method for surgeons to proactively manage their individual learning curve and provide evidence of their efforts to safely improve surgical practice.

Going Paperless? Issues in Converting a Surgical Assessment Tool to an Electronic Version.

UNLABELLED: CONSTRUCT: The competence of a trainee to perform a surgical procedure was assessed using an electronic tool. BACKGROUND: "Going paperless" in healthcare has received significant attention over the past decades given the numerous potential benefits of converting to electronic health records. Not surprisingly, medical educators have also considered the potential benefits of electronic assessments for their trainees. What literature exists on the transition from paper-based to electronic-based assessments suggests a positive outcome. In contrast, work done examining the transition to and implementation of electronic health records has noted that hospitals who have implemented these systems have not gone paperless despite the benefits of doing so. APPROACH: This study sought to transition a paper-based assessment tool, the Ottawa Surgical Competency Operating Room Evaluation (which has strong evidence for validity) to an electronic version, in three surgical specialties (Orthopedic Surgery, Urology, General Surgery). However, as the project progressed, it became necessary to change the focus of the study to explore the issues of transitioning to a paperless assessment tool as we identified an extremely low participation rate. RESULTS: Over the first 3 months 440 assessment cases were logged. However, only a small portion of these cases were assessed using the electronic tool (Orthopedic Surgery = 16%, Urology = 5%, General Surgery = 0%). Participants identified several barriers in using the electronic assessment tool such as increased time compared to the paper version and technological issues related to the log-in procedure. CONCLUSIONS: Essentially, users want the tool to be as convenient as paper. This is consistent with research on electronic health records implementation but different from previous work in medical education. Thus, we believe our study highlights an important finding. Transitioning from a paper-based assessment tool to an electronic one is not necessarily a neutral process. Consideration of potential barriers and finding solutions to these barriers will be necessary in order to realize the many benefits of electronic assessments.

Proper placement of the distal biceps tendon during repair improves supination strength--a biomechanical analysis.

BACKGROUND: Anatomic repair of the distal biceps tendon can be difficult to achieve. This study was designed to compare the effect of anatomic and nonanatomic repairs on forearm supination torque. A nonanatomic repair re-establishes the footprint radial and more anterior to the tuberosity apex, whereas an anatomic repair re-establishes the footprint ulnar and more posterior to the tuberosity apex. METHODS: Eight fresh frozen cadaver arms were surgically prepared and mounted on an elbow simulator. Controlled loads were applied to the long head and short head in positions of pronation, neutral, and supination. This was done with intact tendons and then repeated with repaired tendons that were repaired either anatomically (ulnar position) or nonanatomically (radial position). RESULTS: All anatomic repairs showed no difference compared with intact tendon measurements. In comparing anatomic and nonanatomic repairs, we found no differences in the supination torque when the forearm was in 45° of pronation. However, when the arm was in neutral rotation, we found that 15% less supination torque was generated by the nonanatomic repair. When the arm was tested in 45° of supination, we found that 40% less supination torque was generated in the nonanatomic repair (P = .01). CONCLUSION: This study supports the idea that an anatomic repair of the biceps tendon onto the ulnar side of the radial tuberosity is important. If the tendon is repaired too radially, the biceps will lose the cam effect and may not be able to generate full supination torque when the forearm is in neutral rotation or in supination.

Anatomic repair of the distal biceps tendon cannot be consistently performed through a classic single-incision suture anchor technique.

BACKGROUND: Distal biceps tendon ruptures commonly occur in active men, and surgical repair through a single-incision technique using suture anchors has become common. The current study assessed whether an anatomic repair of the biceps to the radial tuberosity can be consistently achieved through a single-incision technique. METHODS: Acute distal biceps tendon repairs using the single-incision technique were retrospectively reviewed. Computed tomography (CT) scans were obtained to investigate tuberosity dimensions and the position of the suture anchors. An isokinetic dynamometer was used to obtain flexion and supination strength. Disabilities of the Arm, Shoulder and Hand (DASH) scores were collected. RESULTS: CT scans were performed in 27 patients, of which, 21 underwent strength testing. The suture anchor placement averaged 50° radial to the apex of the tuberosity. Strength testing showed flexion strength of the repaired side was equal (97%-106%) to the normal side. Supination strength (80%-86%) and work (66%-75%) performed were both weaker on the repaired side (66%-75%; P < .05). The average DASH score was 10.7. CONCLUSIONS: Ideal suture anchor placement, in the ulnar aspect of the tuberosity, could not be reliably achieved through this single-incision technique. This could have clinical importance because supination strength was not fully restored in this group of patients.

Treatment of olecranon fractures in older individuals: a cross-sectional survey of surgeon treatment preferences.

Background: With an aging population, the incidence of olecranon fractures in older patients is increasing. The standard of care has traditionally included operative management for displaced fractures. Recent literature has called this standard of care into question. Older patients may be at increased risk of operative complications and may have satisfactory functional outcomes with nonoperative management. Given recently evolving evidence, the current treatment preferences of orthopedic surgeons for older patients with displaced olecranon fractures are unknown. Methods: We administered a cross-sectional survey of Canadian orthopedic surgeons via e-mail invitation and online survey form to determine treatment preferences for patients aged 65-75 and >75 years with simple displaced and comminuted displaced stable olecranon fractures. Respondents reviewed representative images and were asked to indicate their preferred treatment based on patient age. We also asked respondents to indicate their perceived importance of 11 patient factors on treatment decision-making. Results: We received 200 responses (33.8% response rate). For patients aged 65-75 years with simple displaced fractures, surgeons preferred tension-band wiring (n = 110, 56%) to plating (n = 82, 42%, P = .005), while only 3% (n = 5) preferred nonoperative treatment. For patients aged >75 years with simple displaced fractures, surgeons preferred operative (n = 144, 73%) to nonoperative management (n = 51, 26%; P < .01) with either tension-band wiring (n = 77, 39%) or plating (n = 67, 34%). In these patients, early range of motion (n = 35, 18%) was preferred to immobilization (n = 16, 8%; P = .004). For comminuted fractures, plate fixation was preferred for patients aged 65-75 years (n = 189, 95%) and >75 years (n = 131, 68%). In patients aged >75 years, this was followed by early range of motion (n = 35, 18%) and immobilization (n = 24, 13%). Of the 11 factors surveyed, participation in high-intensity activities (mean rank = 9.4), independent living (mean rank = 8.8), and disrupted extensor mechanism (mean rank = 8.3) were ranked most highly for increasing likelihood of surgical treatment. Conclusion: In patients aged 65 to 75 years, operative management is favored by most surgeons, with tension-band wiring preferred over plating for simple displaced fractures. In patients aged >75 years, operative management is again preferred by most respondents for simple and comminuted fractures. Despite operative preferences, there is a paucity of quality evidence to guide treatment decision-making, particularly in patients aged >75 years.

The direct anterior approach is safe and shortens hospital length of stay following hemiarthroplasty for neck of femur fracture.

OBJECTIVE: To investigate the safety of using the anterior approach (AA), compared to the lateral approach (LA), in hemiarthroplasty for the treatment of displaced neck of femur fractures. DESIGN: Retrospective case-control match cohort study. SETTING: Level 1 trauma center. PATIENTS: Retrospective review of prospectively collected data for 39 consecutive intracapsular hip fractures treated with hemiarthroplasty using an AA between 2017 and 2021. Patients operated with the AA were matched in 1:2 ratio with patients that had hemiarthroplasty via a LA. MAIN OUTCOME MEASURES: Discharge destination, 90-day emergency room (ER) visit or readmission rate, inpatient and 90-day mortality rate, inpatient medical complications, 90-day mechanical complications, 90-day reoperation, and length of hospital stay (LOS). RESULTS: Discharge destination (p = 0.695), 90-day ER visit or readmission rate (p = 0.315), inpatient (p = 0.719) and 90-day mortality rate (p = 0.815), medical complications (p = 0.524), mechanical complications (p = 0.150) were similar between cohorts. Five patients, all in the LA-group, required re-operations within 90-days (p = 0.106). Patients in AA-group had shorter LOS (9.3 days, 95% CI [7.6-11.1] vs. 14.7 days [95% CI 12.2-17.3], p = 0.002). CONCLUSIONS: The AA can be safely introduced for the treatment of hip fractures. Similar short-term outcomes relative to the LA were identified. The shorter LOS may reflect the improved early functional recovery offered from the muscle-sparing AA technique. Future, level-1 data should include early- and longer term functional outcome along with cost-effectiveness.
