RESUMEN
In young athletes, anterior shoulder instability is a prevalent condition. Because of high-energy traumas, contact athletes often suffer recurrent instability, bone loss and postoperative recurrences. Patients younger than 20 years, symptomatic for more than 6 months, with ≥ 2 dislocations, with off-track Hill-Sachs lesion, glenoid bone loss, ALPSA lesion, Instability Severity Index Score > 3, and Glenoid Track Instability Management Score > 3 are at higher risk of failure. In cases of multiple dislocations with critical or subcritical glenoid bone loss, notably in collision and contact athletes, the Latarjet procedure is widely recognized as the treatment of choice.

INTRODUCTION: Health disparities have been widely studied in the primary care and surgical settings. The purpose of this study was to examine surgical access disparities for orthopaedic surgical cases performed at a large academic health center by comparing the relationship between patient demographic factors and surgical wait time. METHODS: A total of 24,778 orthopaedic surgical cases from 2018 to 2022 at a public, tertiary care, Level I trauma center were retrospectively analyzed to assess for surgical timing disparities based on patient-specific factors, including race, sex, language, and socioeconomic status. RESULTS: Elective surgical cases were completed with an average surgical wait time of 28.11 ± 26.34 days. Urgent surgical cases were completed with an average surgical wait time of 1.23 ± 1.50 days. Patient race, sex, language, and socioeconomic status had no effect on surgical wait time for urgent case scheduling. Female patients had longer average wait times in elective cases, whereas race had a weak association with increased wait time. Two-factor interaction analysis showed no multifactorial effects of patient demographic factors on surgical wait time. Patient race and socioeconomic status were associated with increased distance from surgical sites, although increased distance did not correlate with increased surgical wait time. CONCLUSION: Patient demographic factors did not demonstrate clinically notable associations with surgical timing in this patient cohort, in contrast to previous studies demonstrating the effects of race and socioeconomic status on healthcare outcomes and access. Race and socioeconomic status did correlate with increased distance from surgical centers although distance from surgical sites did not correlate with surgical wait time. This contributes to previous literature on healthcare equity and indicates that surgical wait time may not contribute to the known healthcare inequalities seen in minority and marginalized patients.

BACKGROUND: The risk of developing avascular necrosis (AVN) in the setting of an unstable slipped capital femoral epiphysis (SCFE) that is undergoing treatment with the modified Dunn procedure is not well understood. In addition, since the Loder classification of unstable is reportedly different than actual intraoperatively observed instability (that is, discontinuity between the femoral head epiphysis and proximal femoral metaphysis), the overall risk of developing AVN, as well as the potential complications of treatment of these patients with the modified Dunn procedure, are unknown. QUESTIONS/PURPOSES: To evaluate the modified Dunn procedure for the treatment of patients with epiphyseal-metaphyseal discontinuity, we asked: (1) What was the survivorship free from AVN at 10 years? (2) What was the survivorship free from subsequent surgery and/or complications at 10 years? (3) What were the clinical and patient-reported outcome scores? METHODS: In a retrospective analysis, we identified 159 patients (159 hips) treated with a modified Dunn procedure for SCFE between 1998 and 2020, of whom 97% (155 of 159) had documentation about intraoperatively observed epiphyseal-metaphyseal stability. Of those, 37% (58 of 155) of patients were documented to have intraoperatively observed epiphyseal-metaphyseal discontinuity and were considered eligible for inclusion, whereas 63% (97 of 155) had documented epiphyseal-metaphyseal stability and were excluded. No patients were lost to follow-up before the 2-year minimum. All patients were assessed for survival, but 7% (4 of 58) did not fill out our outcomes score questionnaire. This resulted in 93% (54 of 58) of patients who were available for outcome score assessment. Additionally, 50% (29 of 58) of patients had not been seen within the last 5 years; they are included, but we note that there is uncertainty about their status. The median (range) age at surgery was 13 years (10 to 16), and the sex ratio was 60% (35 of 58) male and 40% (23 of 58) female patients. Sixty-four percent (37 of 58) of patients were classified as acute-on-chronic, and 17% (10 of 58) of patients were classified as acute. Forty-seven percent (27 of 58) of patients presented with severe slips and 43% (25 of 58) of patients with moderate slips based on radiographic classification. All patients underwent surgical hip dislocation with the modified Dunn procedure to correct the slip deformity and provide stabilization. Complications and reoperations were assessed from a review of electronic medical records, and a Kaplan-Meier estimator was used to estimate survivorship free from complications and reoperations at 10 years. Clinical examination results and questionnaire responses were evaluated at minimum 2-year follow-up. RESULTS: Kaplan-Meier survivorship free from AVN was 93% (95% CI 87% to 100%) at 10 years. Survivorship free from any reoperation was 75% (95% CI 64% to 88%) at 10 years. In addition, survivorship free from complications, defined as development of AVN, reoperation, or a Sink Grade II complication or higher, was 57% (95% CI 45% to 73%) at 10 years. The median (range) Merle D'Aubigne Postel score was 18 (14 to 18) for the patients who did not develop AVN, and 12 (6 to 16) for the four patients who developed AVN (p < 0.001). The median modified Harris hip score was 100 (74 to 100) in the non-AVN cohort and 65 (37 to 82) in the AVN cohort (p = 0.001). Median HOOS total score was 95 (50 to 100) in the non-AVN cohort and 53 (40 to 82) in the AVN cohort (p = 0.002). CONCLUSION: Although the modified Dunn procedure is technically challenging, this study shows that in experienced hands, patients with who have demonstrated epiphyseal-metaphyseal discontinuity can be treated with a low risk of AVN and subsequent surgery. Referral of these patients to specialists who have substantial expertise in this procedure is recommended to improve patient outcomes. Prospective, long-term observational studies will help us identify these high-risk patients preoperatively and determine the long-term success of this procedure. LEVEL OF EVIDENCE: Level IV, therapeutic study.

BACKGROUND: In spinal surgery adverse events (AE) and surgical complications (SC) significantly affect patient's outcome and quality of life. The duration of surgery has been investigated in different surgical field as risk factor for complications. The aim of this study is to analyze the correlation between operative time and adverse events in spinal surgery. METHODS: We retrospectively analyzed data collected prospectively in a cohort of 336 patients surgically treated for spinal diseases of oncological and degenerative origin in a single center, between January 2017 to January 2018. Demographics and clinical data were collected. Adverse events were classified using Spinal Adverse Events Severity System version 2 (SAVES-V2) capture system. Focusing on degenerative patients, bivariate analysis and univariate logistic regression were used to determine the association between operative time and complications. RESULTS: A total of 105/336 patients experienced an AE related to surgery, respectively 38% in the oncological group and 28% in the degenerative group. The average age at surgery was 60.3 years (SD 17.1) and the mean operative time was 164.8 ± 138 min. A total of 206 adverse events (30 intraoperative, 135 early postoperative and 41 late postoperative AEs) were recorded. Early post-operative complications accounted for the most recorded AEs (55.5% in the oncological group and 73.2% in the degenerative group). Univariate logistic regression analyses confirmed that operative time correlated with increased risk of intra-operative (p-value = 0.0008), early post-operative (p-value < 0.001) and late post-operative (p-value < 0.001) adverse events. CONCLUSIONS: This study highlights the strong correlation between the occurrence of adverse events in spinal surgery and prolonged operative time and suggests that efforts should be made to minimize the duration of surgical procedures while prioritizing patient's safety, without compromising the technical achievement of the procedure.

BACKGROUND: In modern Hybrid ORs, the synergies of navigation and robotics are assumed to contribute to the optimisation of the treatment in trauma, orthopaedic and spine surgery. Despite promising evidence in the area of navigation and robotics, previous publications have not definitively proven the potential benefits. Therefore, the aim of this retrospective study was to evaluate the potential benefit and clinical outcome of patients treated in a fully equipped 3D-Navigation Hybrid OR. METHODS: Prospective data was collected (March 2022- March 2024) after implementation of a fully equipped 3D-Navigation Hybrid OR ("Robotic Suite") in the authors level 1 trauma centre. The OR includes a navigation unit, a cone beam CT (CBCT), a robotic arm and mixed reality glasses. Surgeries with different indications of the spine, the pelvis (pelvic ring and acetabulum) and the extremities were performed. Spinal and non-spinal screws were inserted. The collected data was analysed retrospectively. Pedicle screw accuracy was graded according to the Gertzbein and Robbins (GR) classification. RESULTS: A total of n = 210 patients (118 m:92f) were treated in our 3D-Navigation Hybrid OR, with 1171 screws inserted. Among these patients, 23 patients (11.0%) arrived at the hospital via the trauma room with an average Injury Severity Score (ISS) of 25.7. There were 1035 (88.4%) spinal screws inserted at an accuracy rate of 98.7% (CI95%: 98.1-99.4%; 911 GR-A & 111 GR-B screws). The number of non-spinal screws were 136 (11.6%) with an accuracy rate of 99.3% (CI95%: 97.8-100.0%; 135 correctly placed screws). This resulted in an overall accuracy rate of 98.8% (CI95%: 98.2-99.4%). The robotic arm was used in 152 cases (72.4%), minimally invasive surgery (MIS) was performed in 139 cases (66.2%) and wound infection occurred in 4 cases (1,9%). Overall, no revisions were needed. CONCLUSION: By extending the scope of application, this study showed that interventions in a fully equipped 3D-Navigation Hybrid OR can be successfully performed not only on the spine, but also on the pelvis and extremities. In trauma, orthopaedics and spinal surgery, navigation and robotics can be used to perform operations with a high degree of precision, increased safety, reduced radiation exposure for the OR-team and a very low complication rate.

OBJECTIVE: This meta-analysis aimed to explore the impact of prophylactic negative pressure wound therapy (NPWT) on the occurrence of deep surgical site infections (SSIs) following orthopedic surgery. METHODS: A systematic search was conducted across Medline, Embase, Cochrane Library, and Web of Science databases for articles concerning NPWT in patients who underwent orthopedic surgery up to May 20, 2024. Using Stata 15.0, the combined odds ratios (ORs) were calculated with either a random-effects model or a fixed-effects model, depending on the heterogeneity values. RESULTS: From a total of 440 publications, studies that utilized NPWT as the experimental group and conventional dressings as the control group were selected to analyze their impact on SSIs. Ultimately, 32 studies met the inclusion criteria. These included 12 randomized controlled trials and 20 cohort studies, involving 7454 patients, with 3533 of whom received NPWT and 3921 of whom were treated with conventional dressings. The results of the meta-analysis demonstrated that the NPWT group had a lower incidence of deep SSIs in orthopedic surgeries than did the control group [OR 0.64, 95% CI (0.52, 0.80), P = 0.0001]. Subgroup analysis indicated a notable difference for trauma surgeries [OR 0.65, 95% CI (0.50, 0.83), P = 0.001], whereas joint surgeries [OR 0.65, 95% CI (0.38, 1.12), P = 0.122] and spine surgeries [OR 0.61, 95% CI (0.27, 1.35), P = 0.221] did not show significant differences. Additionally, when examined separately according to heterogeneity, trauma surgeries exhibited a significant difference [OR 0.50, 95% CI (0.31, 0.80), P = 0.004]. CONCLUSION: The results of our study indicate that the prophylactic use of NPWT reduces the incidence of deep SSIs following orthopedic trauma surgery when compared to the use of conventional dressings. We postulate that the prophylactic application of NPWT in patients at high risk of developing complications from bone trauma may result in improved clinical outcomes and an enhanced patient prognosis.

Technological innovation has advanced the efficacy of spine surgery for patients; however, these advances do not consistently translate into clinical effectiveness. Some patients who undergo spine surgery experience continued chronic back pain and other complications that were not present before the procedure. Defects in healthcare value, such as the lack of clinical benefit from spine surgery, are, unfortunately, common, and the US healthcare system spends $1.4 trillion annually on value defects. In this article, we examine how avoidable complications, postacute healthcare use, revision surgeries, and readmissions among spine surgery patients contribute to $67 million of wasteful spending on value defects. Furthermore, we estimate that almost $27 million of these costs could be recuperated simply by redirecting patients to facilities referred to as centers of excellence. In total, quality improvement efforts are costly to implement but may only cost about $36 million to fully correct the $67 million in finances misappropriated to value defects. The objectives of this article are to present an approach to eliminate defects in spine surgery, including a center-of-excellence framework for eliminating defects specific to this group of procedures.

Introduction: sub-Saharan Africa experiences a significant musculoskeletal trauma burden. Among patients who receive surgical treatment, there have been no reports as to how often surgical care is determined to be "adequate" or, if "inadequate", then what hospital and orthopaedic specialty-specific systems limitations might be prohibitive. Methods: data from patients presenting to the orthopaedic trauma service at a tertiary care center in sub-Saharan Africa were prospectively collected over a 6-week period and then retrospectively reviewed to determine whether the surgical treatment was "adequate" (or otherwise, "inadequate") according to the principle of restoring length, alignment, and rotation. Exclusion criteria included insufficient clinical information; isolated spinal injury; infection; cases involving only removal of hardware; soft-tissue procedures; tumor cases; and medical (non-surgical) conditions. Results: 112 cases were included for analysis. Surgery was indicated in 106 of 112 cases (94.6%), and of those, surgery was performed in 62 cases (58.4%). Among patients who underwent surgery with available post-operative imaging (n=56), surgical treatment was "inadequate" in 24 cases (42.9%). The most common reasons treatment was deemed "inadequate" included unavailability of appropriate implants (n=16), unavailability of intraoperative fluoroscopy (n=10) and incomplete intraoperative evaluation of injury (n=5). Conclusion: several systems limitations prevent the delivery of adequate surgical treatment in patients with acute orthopaedic traumatic injuries, including lack of intraoperative fluoroscopy and lack of implant availability. This study will serve as a useful baseline for ongoing efforts seeking to improve orthopaedic specialty resource availability and facilitate more effective fracture care in this region.

BACKGROUND: Postoperative cognitive impairment are common neural complications in older surgical patients and exacerbate the burden of medical care on families and society. METHODS: A total of 140 older patients who were scheduled for elective orthopaedic surgery or pancreatic surgery with general anaesthesia were randomly assigned to Group S or Group I with a 1:1 allocation. Patients in Group S and Group I received intranasal administration of 400 µL of normal saline or 40 IU/400 µL of insulin, respectively, once daily from 5 minutes before anaesthesia induction until 3 days postoperatively. Perioperative cognitive function was assessed using the Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment-Basic (MoCA-B) at 1 day before and 3 days after surgery and postoperative delirium (POD) incidence was assessed using the 3-minute Diagnostic Interview for CAM (3D-CAM) on postoperative days 1-3. Serum levels of interleukin-6 (IL-6), tumour necrosis factor α (TNF-α), S100-ß and C-reactive protein (CRP) were measured on the first day after surgery. RESULTS: Insulin treatment significantly increased postoperative MMSE and MoCA-B scores in group I than in group S (P < 0.001, P = 0.001, respectively), decreased the incidence of POD within the 3-day postoperative period in Group I than in Group S (10.9% vs 26.6%, P = 0.024), and inhibited postoperative IL-6 and S100-ß levels in Group I compared to Group S (P = 0.034, P = 0.044, respectively). CONCLUSIONS: Intranasal insulin administration is thus suggested as a potential therapy to improve postoperative cognition in older patients undergoing surgery. However, a more standardized multi-centre, large-sample study is needed to further validate these results.

BACKGROUND: Orthopedic procedures often require removing bone or pathological tissue, with traditional methods involving instruments like curettes and rongeurs. However, these methods can be time-consuming and lead to increased blood loss. To mitigate these side effects, vacuum-assisted tools have been developed to aid in tissue removal. These devices enable surgeons to suction tissue without discarding it, potentially improving outcomes in conditions such as osteomyelitis or tumor removal while enabling collection of the material for downstream applications. Despite limited research, vacuum-assisted devices show promise beyond bone marrow harvesting. This study assesses infection and clearance rates, estimated blood loss, and total procedure time associated with the use of vacuum-assisted tissue removal, with a goal to understand if these devices can be used for tissue removal across a variety of pathologic conditions. METHODS: A retrospective cohort study was conducted on patients undergoing orthopedic procedures with the Avitus® Bone Harvester repurposed from its original design from December 1, 2021, to July 1, 2023. Procedures were categorized into oncology, and debridement for infection cases. Infection cases were further categorized into those secondary to trauma and those involving primary infections (osteomyelitis and periprosthetic joint infection). Clinical variables, including demographics, intraoperative details, complications, and follow-up, were reviewed. Statistical analysis included descriptive statistics computed with R Studio. RESULTS: The study included 44 patients, with debridement for infection cases being the most common (primary infection: 45.5%; infection secondary to trauma: 18.1%), followed by oncology cases (36.4%). In all oncology cases, a definitive diagnosis was established using the device, and no post-operative infections were reported. The infection clearance rate was 85.0% for primary infection cases and 50.0% for cases of infection following trauma. Across the entire cohort, the average blood loss was 314.52 mL (sd: 486.74), and the average total procedure time was 160.93 min (sd: 91.07). The overall reoperation rate was 47.7%, with an unplanned reoperation rate of 11.4%. CONCLUSION: The vacuum-assisted bone harvester was effectively utilized in a wide range of debridement and curettage procedures across diverse orthopedic surgeries. In oncology cases, the device enabled effective tissue removal with comparable recurrence rates, demonstrating its potential to minimize contamination while preserving tissue for accurate diagnoses. Additionally, a high rate of osteomyelitis eradication was observed in debridement for primary infection cases (85%). Despite the relatively high reoperation rate of 47.7%, it is crucial to interpret this figure within the context of the varied reasons for reoperation. Many of these reoperations were planned as part of a staged approach to treatment or were unrelated to the device's performance. It is crucial to acknowledge that isolating the device's contribution to these results can be difficult. The utilization of the device should be guided by considerations of cost-effectiveness and patient-specific risk factors.

BACKGROUND: Spinal anesthesia (SA) is a conventional method for proper nerve block in abdominopelvic and lower extremity surgeries. Compared to general anesthesia, SA has reduced perioperative complications significantly. The hyperbaric type of bupivacaine hydrochloride (HB) induces spinal anesthesia more efficiently with a lower incidence of life-threatening adverse reactions like Perioperative hemodynamic changes and respiratory depression. More investigations are needed to define the best dosage that provides adequate anesthesia while reducing adverse effects for each surgical procedure. METHODS: This double-blinded randomized clinical trial compared the consequences of the (12.5mg,15mg,20mg) dosages of HB-bupivacaine in elective lower limb orthopedic surgery. Using block randomization, we allocated 60 participants to three (n = 20) study groups. Utilizing the same protocol of anesthesia induction, outcome variables assumed and measured as the incidence of the adverse effects (Hypotension, Anxiety, Bradycardia, Nausea and Vomiting(N/V), Hypoventilation, and Decreased o2 saturation), and the requirement for intervention to control the unwanted reaction. Addressing that, outcome variables were measured 10 times perioperatively. One-way ANOVA test, the chi2 test, or repeated measures ANOVA test with the Bonferroni adjustment were utilized as appropriate. RESULTS: We found that the incidence of hypotension (P-value:0.02) and the N/V (P-value < 0.001) are associated with the HB-bupivacaine dosage. Contrary, our findings indicate that the incidence of apnea, bradycardia, and hypoventilation did not exhibit a significant dose-dependent pattern between the groups. Repeated measures analysis revealed significant intergroup differences for Herat rate, systolic, diastolic, and mean arterial pressure (group*time Pvalue < 0.001). The observed differences were more prominent 10-30 min after injection of HB-bupivacaine. The regression model claimed that gender (P-value:0.002) and drug dosage (P-value:0.03) significantly predict the incidence of adverse effects. CONCLUSION: Our results, suggest that the administration of the 12.5mg HB-bupivacaine provides adequate anesthesia while minimizing the risk of adverse events for lower limb orthopedic surgeries lasting up to 180 min. TRIAL REGISTRATION: The study was registered at the Clinical Trial Registry Center (IRCT20160202026328N7), Registered on 2022.01.10.

OBJECTIVES: To systematically review the effect of preoperative education on reducing postoperative pain and disability in the short-term and long-term for patients undergoing orthopedic surgery. METHODS: Pertinent randomized controlled trials were retrieved from PubMed, Cochrane Central, Embase, Medline, Scopus and CINAHL from their inception until September 10, 2023. Two authors independently conducted study selection, data extraction, and methodological quality assessment. This review was registered in PROSPERO (CRD42023470282). RESULTS: A total of 37 RCTs were included with 27 of them being pooled for meta-analysis. Low certainty of evidence indicated that there was a small effect of preoperative education (standardized mean difference = - 0.23, 95 % CI = [- 0.39, - 0.07], p = 0.004) or combined preoperative intervention (standardized mean difference = - 0.25, 95 % CI = [- 0.41, - 0.09], p = 0.003) on postoperative pain relief. CONCLUSIONS: Preoperative education and combined preoperative intervention only had a short-term effect on postoperative pain relief, while they were not superior to usual care in postoperative functional recovery, either short-term or long-term. PRACTICE IMPLICATIONS: Both preoperative education and combined preoperative intervention are effective in pain control around a week postoperatively. However, optimal contents, durations, and dose of education warrant further investigation.

BACKGROUND: With orthopedic surgery increasing year on year, the main challenges in bone drilling are thermal damage, mechanical damage, and drill skid. The need for new orthopedic drills that improve the quality of surgery is becoming more and more urgent. METHODS: Here, we report the skidding mechanism of drills at a wide range of inclination angle and propose two crescent drills (CDTI and CDTII). The anti-skid performance and drilling damage of the crescent drills were analyzed for the first time. Inclined bone drilling experiments were carried out with crescent drills and twist drills and real-time drilling forces and temperatures were collected. RESULTS: The crescent drills are significantly better than the twist drill in terms of anti-skid, reducing skidding forces, thrust forces and temperature. The highest temperature is generated close to the upper surface of the workpiece rather than at the hole exit. Finally, the longer crescent edge with a small and negative polar angle increases the rake angle of the cutting edge and reduces thrust forces but increases skidding force and temperature. This study can promote the development of high-quality orthopedic surgery and the development of new bone drilling tools. CONCLUSION: The crescent drills did not skid and caused little drilling damage. In comparison, the CDTI performs better in reducing the skidding force, while the CDTII performs better in reducing the thrust force.

PURPOSE: The current standard method for pectus excavatum (PE) repair is the Nuss procedure. One major postoperative complication is the displacement of the implanted metal bar, which is used to remodel the chest wall. Blocking the possible ways that the bar can be displaced with the use of stabilizers and peri/intracostal sutures has reduced the incidence of bar displacement. Despite the modifications, bar dislocation is often reported. We adopted the medial position stabilizer placement method and imposed no postoperative restrictions. In this study, we analyzed the bar dislocation rate with this modification and concurrent postoperative full activity. METHODS: Nuss procedure modification where stabilizers are placed bilaterally in the medial location was done on patients irrespective of age and Haller index greater than 3.25. A single bar was used for all patients. Cryoanalgesia was performed on every patient. No postoperative restrictions were imposed on the patients. Full immediate activities, including sports, were allowed. RESULTS: 114 patients (103 male, 11 female) were analyzed from 2016 to 2023. The median age was 15 years old. There was zero incidence of bar displacement. The combined incidence of other postoperative complications was 4%: 2 wound infections and 2 hematoma formations, both needing incision and drainage. CONCLUSION: Bilateral medial stabilizer placement resulted in no incidence of bar dislocation.

BACKGROUND: Assessment of orthopaedic surgery trainees is traditionally based on subjective evaluation by faculty. The recent push for value-based health care has placed a premium on improving patient outcomes. As a result, surgical training evaluations for orthopaedic trainees are evolving to include more objective measures to evaluate competency. PURPOSE: To develop and subsequently demonstrate the efficacy of a novel surgical skills assessment for orthopaedic sports medicine fellows. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: A team of 14 fellowship-trained orthopaedic sports medicine surgeons developed objective scoring rubrics for anterior cruciate ligament reconstruction (ACLR) and rotator cuff repair (RCR) using a modified Delphi process. Rubrics were designed based on 10 surgical steps with a grading scale (1-5) based on core competencies with a maximum summative score of 50. Fourteen orthopaedic fellows across a regionally diverse group of sports medicine-accredited fellowship programs were invited to complete both an ACLR and RCR in a surgical skills laboratory at the beginning and end of their fellowship year. Individual surgical steps, overall performance, and total procedure time were evaluated by a single sports medicine surgeon for both sessions. RESULTS: Thirteen of 14 fellows completed both pre- and post-fellowship assessments. For the ACLR procedure, the pre-fellowship mean summative score was 25.4 (SD, 4.4) and the post-fellowship mean summative score was 38.6 (SD, 4.1), which was a statistically significant improvement (P < .001). For the RCR procedure, the pre-fellowship mean summative score was 26.6 (SD, 5.4) and the post-fellowship mean summative score was 38.8 (SD, 4.3), which was also a statistically significant improvement (P < .001). The mean time to completion for the ACLR procedure was 82.3 minutes (SD, 4.3 minutes) pre-fellowship, which improved to 69.7 minutes (SD, 11.6 minutes) post-fellowship (P = .002). The mean time to completion for the RCR procedure was 85.5 minutes (SD, 5.0 minutes) pre-fellowship, which improved to 76.4 minutes (SD, 7.0 minutes) post-fellowship (P < .001). CONCLUSION: This surgical skills program represents the first standardized and reproducible instrument for the evaluation of 2 arthroscopic sports medicine procedures in the United States. Orthopaedic sports medicine fellows improved significantly in aggregate over their fellowship year with regard to the ACLR and RCR. The described program has the potential to serve as both a training tool and formal orthopaedic sports medicine fellow assessment.

This study aims to provide radiation reference levels in orthopaedic surgery. A total of 753 procedures were collected within 1 y. Categories containing several similar procedures were created based on four criteria: same anatomical area, same level of complexity, only single procedures, and at least 10 cases per category. Exposure was defined in terms of air kerma-area product, fluoroscopy time, and air kerma at the patient entrance reference point. For common procedures, median effective doses to patient were calculated using the Monte Carlo Software PCXMC. Most irradiating procedure in this study i.e. intramedullary nailing of the proximal femur was equivalent to an air kerma at the patient entrance reference point of 37.1 mGy, which is ~50 times lower than the threshold for acute deterministic effects of radiation. Optimization remains a must to reduce the dose while maintaining the image quality and reducing the likelihood of stochastic effects.

STUDY OBJECTIVE: This study aims to evaluate the impact of Supreme™ laryngeal masks versus endotracheal tubes on atelectasis during general anesthesia using lung ultrasound (LUS), and provide evidence for respiratory management. DESIGN: A single-center, double-blind, randomized controlled trial was conducted. SETTING: The study was conducted in both the operating room and the post-anesthesia care unit, with follow-up assessments performed in the ward. PATIENTS: Enrollment included 180 cases undergoing non-laparoscopic surgeries in gynecology, urology, and orthopedic limb surgeries. INTERVENTIONS: Patients were randomly assigned 1:1 to the endotracheal intubation or laryngeal mask group. MEASUREMENTS: LUS scores were recorded across 12 lung regions at baseline, 15 min after airway establishment, at the end of surgery, and 30 min following airway removal. Outcome measures encompassed the oxygenation index, dynamic lung compliance, incidence of postoperative pulmonary complications, throat pain, and other postoperative complications assessed at 24 and 48 h postoperatively. The primary outcome focused on the LUS score in all 12 lung regions at 15 min after airway establishment. MAIN RESULTS: Intention-to-treat analysis of 177 subjects revealed endotracheal intubation led to significantly higher LUS scores at 15 min {P < 0.001, mean difference 4.15 ± 0.60, 95% CI [2.97, 5.33]}, end of surgery (P < 0.001, mean difference 3.37 ± 0.68, 95% CI [2.02, 4.72]), and 30 min post-removal (P < 0.001, mean difference 2.63 ± 0.48, 95% CI [1.68, 3.58]). No major complications occurred in the two groups. CONCLUSIONS: Compared to endotracheal intubation, laryngeal masks effectively reduce atelectasis formation and progression in gynecological, urological non-laparoscopic, and orthopedic limb surgeries. However, caution is warranted when generalizing these findings to surgeries with a higher risk of laryngeal mask leakage or obese patients. Additionally, the efficacy of laryngeal masks in reducing postoperative atelectasis remains uncertain when comprehensive monitoring of muscle relaxation and reversal therapy is employed.
