Does spinopelvic alignment affect femoral head cartilage and the proximal femoral physis in slipped capital femoral epiphysis? A finite element analysis.

BACKGROUND: Slipped capital femoral epiphysis is a prevalent pediatric hip disorder. Recent studies suggest the spine's sagittal profile may influence the proximal femoral growth plate's slippage, an aspect not extensively explored. This study utilizes finite element analysis to investigate how various spinopelvic alignments affect shear stress and growth plate slip. METHODS: A finite element model was developed from CT scans of a healthy adult male lumbar spine, pelvis, and femurs. The model was subjected to various sagittal alignments through reorientation. Simulations of two-leg stance, one-leg stance, walking heel strike, ascending stairs heel strike, and descending stairs heel strike were conducted. Parameters measured included hip joint contact area, stress, and maximum growth plate Tresca (shear) stress. FINDINGS: Posterior pelvic tilt cases indicated larger shear stresses compared to the anterior pelvic tilt variants except in two leg stance. Two leg stance resulted in decreases in the posterior tilted pelvi variants hip contact and growth plate Tresca stress compared to anterior tilted pelvi, however a combination of posterior pelvic tilt and high pelvic incidence indicated larger shear stresses on the growth plate. One leg stance and heal strike resulted in higher shear stress on the growth plate in posterior pelvic tilt variants compared to anterior pelvic tilt, with a combination of posterior pelvic tilt and high pelvic incidence resulting in the largest shear. INTERPRETATION: Our findings suggest that posterior pelvic tilt and high pelvic incidence may lead to increased shear stress at the growth plate. Activities performed in patients with these alignments may predispose to biomechanical loading that shears the growth plate, potentially leading to slip.

Management of Acute Wounds - Expert Panel Consensus Statement.

SIGNIFICANCE: The Wound Healing Foundation recognized the need for consensus-based unbiased recommendations for the treatment of wounds. As a first step, a consensus on the treatment of chronic wounds was developed and published in 2022.(1) The current publication on acute wounds represents the second step in this process. Acute wounds may result from any number of conditions, including burns, military and combat operations, and trauma to specific areas of the body. The management of acute wounds requires timely and evidence-driven intervention to achieve optimal clinical outcomes. This consensus statement provides the clinician with the necessary foundational approaches to the causes, diagnosis and therapeutic management of acute wounds. Presented in a structured format, this is a useful guide for clinicians and learners in all patient care settings. RECENT ADVANCES: Recent advances in the management of acute wounds have centered on stabilization and treatment in the military and combat environment, Specifically advancements in hemostasis, resuscitation, and the mitigation of infection risk through timely initiation of antibiotics and avoidance of high pressure irrigation in contaminated soft tissue injury. . CRITICAL ISSUES: Critical issues include infection control, pain management and the unique considerations for the management of acute wounds in pediatric patients. FUTURE DIRECTIONS: Future directions include new approaches to preventing the progression and conversion of burns through the use of the microcapillary gel, a topical gel embedded with the anti-inflammatory drug infliximab.(38) Additionally, the use of three-dimensional bioprinting and photo-modulation for skin reconstruction following burns is a promising area for continued discovery.

A Quality Improvement Initiative to Improve After-visit Summary Distribution in Orthopedic Outpatient Clinics.

Communication and patient education are key to effective healthcare encounters and improved health outcomes. The after-visit summary (AVS) is an integral communication and education tool for patients and families. Without effective communication, gaps in comprehension may result in decreased satisfaction with medical encounters, lack of adherence to recommended treatment plans, missed appointments, and increased malpractice claims. Methods: We initiated a quality improvement (QI) initiative implementing concepts derived from the Institute for Healthcare Improvement (IHI) model, including plan-do-study-act cycles, to increase AVS distribution rates in a high-volume, fast-paced ambulatory pediatric orthopedic clinic. Interventions included staff education and training, trainee instruction, enlistment of electronic medical record superusers to enhance the distribution process, and provision of regular, transparent communication of individual and team performance. The impact of interventions was measured using a p-chart. Results: There was a consistent improvement in the rate of AVS distribution with each intervention implemented. The distribution rate on project initiation was 81.9%, with a final rate of 95.7%. The most statistically significant shift occurred following the final intervention, which included sharing unblinded individual performance data. Conclusion: Our data demonstrate that a dedicated QI program using IHI methodology improved AVS distribution rates in a pediatric orthopedic clinic. Consistently distributing the AVS affords our patients and families a better opportunity to review pertinent visit information, education, medication changes, and upcoming appointments.

Outcomes of Pediatric Scaphoid Nonunions Treated With Distal Radius Cancellous Autograft.

BACKGROUND: The optimal management of pediatric scaphoid fracture nonunions is controversial. We hypothesize that pediatric patients with scaphoid fracture nonunions will have favorable functional outcomes with the utilization of nonvascularized distal radius cancellous autograft with open reduction and internal fixation (ORIF). METHODS: A review was performed from 2012 to 2017 identifying skeletally immature patients with scaphoid fracture nonunions treated with ORIF and nonvascularized distal radius cancellous autograft, including demographic data, mechanism of injury, length of time from injury to treatment, operative procedure, length of immobilization, time to union, and complications. RESULTS: Ten patients (9 males, 1 female) met inclusion criteria. Mean age was 14.3 SD 1.5 years. The majority of fractures were sustained during sports or secondary to a fall. Mean time between injury and orthopaedic evaluation was 33 weeks (SD 20 wk). Eight fractures occurred at the waist, and 2 occurred at the proximal pole. Four patients had a humpback deformity, and three presented with a dorsal intercalated segmental instability deformity. Nine patients were treated with a single cannulated compression screw with distal radius autograft. One patient also received a single Kirschner wire fixation in addition to a single cannulated screw and graft. Patients underwent a mean postoperative immobilization period of 14 SD 5 weeks. Two patients received a bone stimulator postoperatively. Radiographic union was documented after initial surgery in nine patients, with mean time to union of 17 SD 5 weeks. The 1 patient with persistent radiographic nonunion underwent revision fixation and repeat nonvascularized distal radius autograft, achieving union and resolution of symptoms. All patients ultimately reported full return to activity. CONCLUSIONS: Pediatric scaphoid fracture nonunions that undergo ORIF using nonvascularized distal radius cancellous autograft have favorable rates of consolidation and functional outcomes. Surgeons should consider this source of grafting in operative management of scaphoid nonunions in children and adolescents. LEVEL OF EVIDENCE: Level IV, therapeutic.

Influence of seasonal variability on orthopedic surgical outcomes in pediatric patients: a review of surgical site infections.

Surgical site infections (SSIs) are challenging, with highly variable reported rates for children undergoing orthopedic surgery. It has been shown in adults that there is seasonal variability in SSI rates, with peak incidences in the summer months. We reviewed 8766 pediatric orthopedic procedures completed at a quaternary children's hospital over a 43-month period. Data collected included: age, sex, BMI, season of procedure, cultures, and other variables related to risks and treatment of SSIs. Of 4875 male and 3891 female pediatric patients undergoing orthopedic procedures, 47 patients (0.54%) with an average age of 11.3 years (range: 2.0-18.6) developed an SSI. Average time between surgery and diagnosis was 27.7 ± 19.8 days. Sixty percent of SSI patients had a BMI in the 85th percentile or above, and 49% of SSI patients had a BMI above the 95th percentile. Thirty-eight patients had positive cultures, with most common infections being due to methicillin-sensitive Staphylococcus aureus in 11 (29%) cases, polymicrobial in 9 (24%), pseudomonas in 5 (13%), and coagulase-negative Staphylococcus in 5 (13%). SSI rate in winter (0.18%) was significantly lower than in autumn (0.77%, P = 0.006) and summer (0.69%, P = 0.02). The difference did not reach statistical significance from the infection rate in spring (0.53%, P = 0.06). Twenty-nine (62%) SSI cases were considered elective in nature, and the other 18 (38%) cases were for acute traumatic injuries. There is a significantly higher SSI rate in summer and autumn than winter for pediatric patients undergoing orthopedic surgeries. Most patients with SSIs were overweight or obese.

Functional outcomes of a modified Duran postoperative rehabilitation protocol after primary repairs of pediatric hand flexor tendon injuries.

The objective of this study was to determine whether pediatric patients undergoing flexor tendon repair who underwent 4 weeks of immobilization followed by a modified Duran controlled passive motion rehabilitation protocol will have favorable outcomes. A study was performed at a tertiary pediatric hospital of patients <18 years who underwent primary flexor tendon repairs in zones 1-4. Outcomes were calculated by total active motion and classified by the original Strickland criteria or Buck-Gramcko criteria. Twenty-eight patients with 34 injured fingers were included. Mean age was 11.4 years (range 2.4-17.9) with 17 males (61%) and 11 females (39%). Thirty-five percent of injuries occurred in zone 1; 35% zone 2; 6% zone 3; and 24% zone 4. All underwent a modified Duran postoperative rehabilitation protocol following a period of immobilization. The majority of patients achieved favorable outcomes, with 86% of cases classified as good/excellent. Thirty (88%) cases received surgery acutely (within 3 weeks). Of these, 70% achieved excellent outcomes, 17% good, and 13% fair. Four (12%) chronic cases underwent primary repair (range 24-68 days), achieving excellent outcomes in 50%, good in 25%, and fair in 25%. Three (75%) patients with delayed primary repair exhibited stiffness, which was greater than the 17% of patients with acute repairs ( P = 0.03). Approximately 1 month of immobilization followed by a modified Duran rehabilitation protocol leads to favorable outcomes in children with flexor tendon repairs. Children with delayed surgery (>3 weeks) who underwent primary repair generally still achieved good outcomes but were more likely to have stiffness. Level of evidence: III.

Assessing the Prevalence of Microaggressions in Plastic Surgery Training: A National Survey.

There has been increased awareness of microaggressions occurring during medical training. However, the prevalence and characteristics of microaggressions specifically in plastic surgery residency remain unknown. We aimed to fill this literature gap by conducting a nationwide survey to better understand and characterize microaggressions in plastic surgery training. METHODS: A survey was distributed between March and May 2021 via the American Society of Plastic Surgeons Resident Representatives to 1014 integrated and 214 independent track plastic surgery trainees in the United States. Multiple Pearson's chi-square of independence and Fisher exact tests evaluated comparisons of microaggressions by sex, race, Hispanic origin, sexual orientation, and year in training. A multivariate regression analysis assessed associations between variables. RESULTS: One hundred twenty-five participants responded to the survey (response rate: 10.2%). Of those who responded, 68.8% had experienced microaggressions in the past year. Female trainees experienced microaggressions more frequently than male trainees (P < 0.05). Asian trainees had higher odds to be a target of microaggressions compared with White trainees (P = 0.013). Nonheterosexual trainees were more likely to have experienced microaggressions compared with heterosexual trainees (P < 0.05). Independent trainees were more likely to experience microaggressions than PGY 1-2 and 3-4 integrated residents (P < 0.05). CONCLUSIONS: Approximately seven in every 10 trainees stated that they experienced microaggressions in the past year. Females, racial minorities, sexual minorities, and independent trainees had higher odds of reporting that they experienced microaggressions. Further studies are needed to assess the implementation of strategies that address this problem to resolve inequities.

A quality improvement initiative to reduce cast transitions in a pediatric hospital.

A quality improvement protocol was implemented in a large tertiary care pediatric hospital to reduce the rate of transitions from emergency department (ED)-applied casts to another form of immobilization (waterproof cast, removable brace, or sling). The local standard of care prior to implementing this quality improvement project involved applying long-arm casts in the ED for children presenting with stable upper extremity injuries (those not requiring a reduction). We created a multidisciplinary quality improvement team with orthopedic and ED providers, as well as cast technicians, with the aim of reducing the transition rate of ED-applied casts in clinic by 50%. Multiple Plan-Do-Study-Act cycles were performed and data were evaluated monthly. Charge fees were determined to assess differences in costs between splints and casts. An independent samples t-test for equality of means was used to determine the ED length of stay of each group. Baseline data determined a cast transition rate of 59.9%. After implementing the quality improvement protocol, the cast transition rate was reduced to 25.0%, a 58% reduction. The length of stay in the ED for a patient receiving a splint as opposed to a cast was 26.2 ± 8.0 min shorter. The charge to a patient receiving a splint rather than an ED-applied cast was $291.25 less. In conclusion, implementation of a multidisciplinary quality improvement protocol resulted in a more than 50% reduction in the transition rate of ED-applied casts in the clinic. Furthermore, healthcare charges to families were reduced by nearly $130 000 annually after implementation of this protocol.

Harassment, Discrimination, and Bullying in Orthopaedics: A Work Environment and Culture Survey.

INTRODUCTION: The presence of discrimination, bullying, sexual harassment, and harassment (DBSH) in the healthcare workplace negatively affects the health and well-being of providers and is associated with poor mental health, low self-esteem, high levels of absenteeism, and low levels of productivity. METHODS: The American Academy of Orthopaedic Surgeons (AAOS) developed and distributed a survey to a subset of AAOS members to assess the climate of workplace safety and overall workplace culture. Women and underrepresented minority (URM) AAOS members and an equal number of randomly selected non-URM men were invited to participate in the survey. RESULTS: Nine hundred twenty-seven of 5,638 (16.4%) members responded to the survey. Sixty-six percent of respondents reported experiencing DBSH behavior with specific exposures to DBSH of 79%, 55%, 47%, and 40%, respectively. Women (81%) were more likely than men (35%) to have experienced these behaviors. Fifty-eight percent of respondents reported that their workplaces were equipped to deal effectively with DBSH behaviors. DISCUSSION: DBSH behaviors occur in the orthopaedic workplace. More attention to these issues is necessary to ensure that all orthopaedic surgeons in training and in practice have a safe work environment that is inclusive, equitable, and health-promoting. LEVEL OF EVIDENCE: N/A.

Improving Sexual, Racial, and Ethnic Diversity in Orthopedics: An Imperative.

Orthopedics is the least diverse medical specialty. From residents to faculty, the representation of women and underrepresented minorities lags behind that of all other specialties. The crux of the disparity stems from the pipeline, as medical students who are female and are underrepresented minorities are simply not applying to orthopedic surgery. Grassroots efforts providing early exposure to orthopedics have led to a considerable proportion of alumnae pursuing science majors and eventually medical school. Institutions with a stated commitment to diversity have successfully produced residency classes with greater diversity. The culture should be one that combats biases, dispels misconceptions about orthopedics, and prioritizes recruiting/retaining diverse providers. [Orthopedics. 2020;43(3):e134-e140.].

Pediatric Medial Epicondyle Fracture Management: A Systematic Review.

BACKGROUND: There remains controversy surrounding the treatment of pediatric medial epicondyle fractures. This systematic review examines the existing literature with the aim to elucidate optimal management strategies. METHODS: A systematic review using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was executed. All data collection was completed by August 01, 2018. Functional outcomes, diagnostic imaging, athlete management, union rates, ulnar nerve symptoms, surgical methods, surgical positioning, and posttreatment protocols were categorized and recorded. Frequency-weighted mean values were calculated with associated SDs. RESULTS: Thirty-seven studies with 1022 patients met the inclusion criteria. Functional outcomes for patients were mostly good following operative and nonoperative management. The most common complication was a slight loss of elbow extension (7.6±5.9 degrees) and flexion (13.3±5.8 degrees). Operative treatment was associated with higher union rates than nonoperative management (700/725, 96% vs. 69/250, 28%; P<0.001). Standard diagnostic imaging techniques to measure displacement were unreliable with a newly proposed axial view having high inter-rater and intrarater reliability. The most common surgical method used was open reduction and internal fixation with Kirschner wires. Whereas surgical management of patients with associated ulnar nerve symptoms led to symptom resolution, nonoperative management occasionally led to the development of these symptoms. Elbow range of motion was initiated at ~2.8±1.4 (range, 0 to 8 wk) weeks after surgery and 3.4±1.2 (range, 3 to 5 wk) weeks without surgery (P<0.001). CONCLUSIONS: Although there is still no consensus on treatment of pediatric medial epicondyle fractures, both operative and nonoperative approaches result in good outcomes. LEVEL OF EVIDENCE: Level IV-therapeutic.

Use of Standardized Letters of Recommendation for Orthopaedic Surgery Residency Applications: A Single-Institution Retrospective Review.

BACKGROUND: Standardized letters of recommendation (SLORs) were introduced to provide a more objective method of evaluating applicants for orthopaedic surgery residency positions. We sought to establish whether there exists an association between the SLOR summative rank statement (SRS), which is a question that asks the letter-writing authors where they would rank a student relative to other applicants, and success in matching into orthopaedic surgery residency. METHODS: We reviewed 858 applications to an orthopaedic surgery residency program from 2017 to 2018. Data on 9 assessment categories, SRSs, and written comments in the SLORs were extracted. The match success of applicants was determined by an internet search algorithm. Logistic regression was used to evaluate the association between the SRSs and match success. The Spearman correlation was performed between the SRSs and other variables. RESULTS: Only 60% of all LORs were SLORs. With 24% of the SLORs, a supplemental letter was used. Median percentile rank ranged from 90% to 100% for the 9 categories in the SLORs. Recommendations of "high rank" or higher were found in 88% of the SRSs. The mean of the SLOR SRSs was associated with match success. CONCLUSIONS: The mean of the SLOR SRSs was associated with match success. However, the SLOR is not uniformly used. Future efforts should be devoted to improving question design and validity in order to better discriminate among applicants, increase adherence to the rating scale, and quantify the strength of the written comments in the SLOR.

Writing Group Increases Quality Improvement Writing Competency.

Quality improvement (QI) is critically important in current medical practice. Although many QI courses teach improvement science and methods, formal education in writing QI manuscripts for academic journal publication is lacking. The authors developed a QI Writing program, consisting of educational sessions with both coach and peer mentors, to improve comfort and productivity in preparing QI manuscripts for publication. Program participants conducted pre- and post-course QI writing skills self-evaluations in 4 competency domains: SQUIRE guidelines, writing for peer-reviewed journals, QI publication submission steps, and critically examining QI results. Course success was measured by the number of manuscripts submitted for publication. QI writing competencies doubled in 3 of 4 domains and increased 70% in the fourth. Fifteen of 17 (88%) course participants submitted manuscripts to a peer-reviewed journal, and 12 have been accepted to date. A formal writing group with didactic content and committed mentors increases QI writing competencies and manuscript submissions to peer-reviewed journals.

Increasing Brace Treatment for Pediatric Distal Radius Buckle Fractures: Using Quality Improvement Methodology to Implement Evidence-based Medicine.

BACKGROUND: Multiple randomized trials have showed equivalent outcomes and improved patient/family satisfaction using a removable brace to treat pediatric distal radius buckle fractures (DRBF). We tested the hypothesis that we could use quality improvement (QI) methodology to increase the proportion of patients with DRBF treated with removable braces at 2 tertiary care orthopaedic clinics from a baseline of 34.8% to 80%. METHODS: Clinic billing records were reviewed monthly to determine treatment (brace vs. cast) of DRBF and tracked using control charts (p-chart). Balance measures including correct application of the diagnostic criteria and algorithm were monitored. Process measures including the number of follow-up visits, radiographs obtained, and total cost of treatment were collected. Baseline data were obtained over a 3-month period, followed by a 12-month period of interventions using Plan-Do-Study-Act cycles targeting both individuals and groups of providers. RESULTS: The proportion of DRBF treated in a brace increased from a combined baseline of 34.8% to a combined 84% at the end of the study period. Following intervention, 83% (15/18) of providers began using braces for a majority of patients (defined as >67%), with only 1 provider continuing to use casts 100% of the time. Patient preference was cited as the most common reason for use of cast treatment. There was a significant decrease in the number of radiographs obtained at 1 of 2 institutions. The charges for brace treatment averaged $630 less per patient than for cast treatment, leading to an estimated medical-cost savings of $205,000 following intervention. CONCLUSIONS: Implementation of brace treatment for pediatric DRBF using QI methodology resulted in a shift toward brace treatment in the majority of patients, leading to substantial medical and nonmedical cost savings. Although patient preference was cited as the most common reason for persistent cast treatment, the data show the use of cast treatment to be more dependent upon individual provider preference. LEVEL OF EVIDENCE: Level II-therapeutic.

Treatment of Acute Seymour Fractures.

BACKGROUND: Seymour fractures are distal phalanx fractures in children with a juxta-epiphyseal pattern. The purpose of our study was to investigate the treatments, outcomes, operative ;indications, and antibiotic choice for acute Seymour fractures (presenting within 24 h of injury), to better define optimal management. We hypothesized that: (1) cephalexin provides adequate antibiotic coverage for acute Seymour fractures; (2) most injuries will achieve good outcomes with management in the emergency department (ED) alone; and (3) indication for operative intervention is unsuccessful or unstable reduction in the ED. METHODS: We performed a retrospective study of patients under 18 years old treated at a large pediatric hospital from 2009 to 2017 for an acute Seymour fracture. Study outcomes included management and antibiotic type, infection, fracture healing, malunion, physeal disturbance, nail dystrophy, antibiotic failure, and need for unplanned operative intervention. RESULTS: Mean age of patients was 10 years, with 43 males and 22 females sustaining 65 Seymour fractures. Fifty-eight cases (89%) were initially managed in the emergency department. Seven cases were initially managed with an operative intervention that included I&D, open reduction, and K-wire fixation. The most commonly cited surgical indication was unsuccessful closed reduction. Four patients initially managed in the ED required an unplanned operation, usually because of fracture redisplacement. Complications were rare, with superficial infections being most common. CONCLUSIONS: Most acute Seymour fractures can be successfully managed in the emergency department if stable reduction is achieved. LEVEL OF EVIDENCE: Level IV, therapeutic.

A Quality Improvement Initiative Reduces Cast Complications in a Pediatric Hospital.

BACKGROUND: Casts, while frequently used as routine treatment in pediatric orthopaedic practice, are not without complications. At our large tertiary care pediatric hospital, the baseline rate of all casting complications was 5.6 complications per 1000 casts applied (0.56%). We tested the hypothesis that we could use quality improvement (QI) methodology to decrease the overall cast complication rate and improve patient care. METHODS: We initiated a QI program implementing concepts derived from the Institute for Healthcare Improvement models, including Plan-Do-Study-Act cycles, to decrease our cast complication rate. A resident casting education program was developed with a competency "checklist" to ensure that casts are applied, bivalved, and removed in a safe and standardized manner to prevent patient harm. AquaCast Saw Stop Protective Strips were required to be applied with every cast application. A review of our facility's processes and procedures determined adequate measures were in place to effectively manage inventory and maintenance of cast-saw blades. RESULTS: With the multimodal QI intervention, our cast complication rate was reduced to 1.61 complications per 1000 applications, a >90% improvement. CONCLUSIONS: Implementation of QI concepts to perform a QI initiative resulted in a shift toward fewer cast complications, leading to overall improved patient care at a large tertiary pediatric hospital. LEVEL OF EVIDENCE: Level II-prospective cohort study.
