Are Generative Pretrained Transformer 4 Responses to Developmental Dysplasia of the Hip Clinical Scenarios Universal? An International Review.

OBJECTIVE: There is increasing interest in applying artificial intelligence chatbots like generative pretrained transformer 4 (GPT-4) in the medical field. This study aimed to explore the universality of GPT-4 responses to simulated clinical scenarios of developmental dysplasia of the hip (DDH) across diverse global settings. METHODS: Seventeen international experts with more than 15 years of experience in pediatric orthopaedics were selected for the evaluation panel. Eight simulated DDH clinical scenarios were created, covering 4 key areas: (1) initial evaluation and diagnosis, (2) initial examination and treatment, (3) nursing care and follow-up, and (4) prognosis and rehabilitation planning. Each scenario was completed independently in a new GPT-4 session. Interrater reliability was assessed using Fleiss kappa, and the quality, relevance, and applicability of GPT-4 responses were analyzed using median scores and interquartile ranges. Following scoring, experts met in ZOOM sessions to generate Regional Consensus Assessment Scores, which were intended to represent a consistent regional assessment of the use of the GPT-4 in pediatric orthopaedic care. RESULTS: GPT-4's responses to the 8 clinical DDH scenarios received performance scores ranging from 44.3% to 98.9% of the 88-point maximum. The Fleiss kappa statistic of 0.113 ( P = 0.001) indicated low agreement among experts in their ratings. When assessing the responses' quality, relevance, and applicability, the median scores were 3, with interquartile ranges of 3 to 4, 3 to 4, and 2 to 3, respectively. Significant differences were noted in the prognosis and rehabilitation domain scores ( P < 0.05 for all). Regional consensus scores were 75 for Africa, 74 for Asia, 73 for India, 80 for Europe, and 65 for North America, with the Kruskal-Wallis test highlighting significant disparities between these regions ( P = 0.034). CONCLUSIONS: This study demonstrates the promise of GPT-4 in pediatric orthopaedic care, particularly in supporting preliminary DDH assessments and guiding treatment strategies for specialist care. However, effective integration of GPT-4 into clinical practice will require adaptation to specific regional health care contexts, highlighting the importance of a nuanced approach to health technology adaptation.

What is New in Pediatric Orthopaedic Foot and Ankle.

BACKGROUND: This paper aims to report on the last 5 years of relevant research on pediatric foot and ankle pathology with specific focus on clubfoot, congenital vertical talus, toe walking, tarsal coalitions, pes planovalgus with or without accessory navicular, foot and ankle trauma, and talar dome osteochondritis dessicans. METHODS: The Browzine platform was used to review the table of contents for all papers published in the following target journals related to the treatment of pediatric foot and ankle conditions. Search results were further refined to include clinical trials and randomized controlled trials published from March 1, 2015 to November 15, 2021. RESULTS: A total of 73 papers were selected for review based on new findings and significant contributions in treatment of clubfoot, congenital vertical talus, toe walking, tarsal coalitions, pes planovalgus with or without accessory navicular, foot and ankle trauma, and talar dome osteochondritis dessicans. Also included were several papers that did not fit into any of these categories but provided new insight into specific foot and ankle pathologies. CONCLUSIONS: Treatment strategies for children with foot and ankle pathology are continually evolving. We review many of the most recent publications with the goal of improving understanding of these pathologies and highlighting current best practices. LEVEL OF EVIDENCE: Level III.

Clubfoot Activity and Recurrence Exercise Study (CARES).

BACKGROUND: Approximately half of treated clubfoot patients initially corrected with the Ponseti method experience relapse that requires additional treatment. The consequences of relapse on childhood activity levels have not been well studied. Ponseti noted lower functional ratings at 18-year follow-up in clubfoot patients who had undergone tibialis anterior tendon transfer for relapse. METHODS: Clubfoot Activity and Recurrence Exercise study (CARES) is an observational, prospective cohort study that compares physical activity in 30 clubfoot patients without and with relapse. Eligible participants were 5 to 10 years old, diagnosed with idiopathic clubfoot at birth, and had not received any clubfoot treatment for at least 6 months before study. Recruitment for this study occurred in-person and through Facebook clubfoot groups. Consented participants wore Fitbits secured to their wrists for at least 14 days, and completed a demographic survey, Child Health Questionnaire (CHQ), and the clubfoot disease-specific instrument (CDSI). Participants' daily activity was monitored through Fitabase. RESULTS: Participants without and with clubfoot relapse had similar daily step counts, distance walked, and step intensities, except for moderately active step intensity, which was higher in the clubfoot relapse group. Total steps, total distance, distances (very active, moderately active), minutes (very active, fairly active), and lightly active intensity of steps were significantly higher for participants whose families earn more than $100,000 per year. Various physical activities and sports were reported by both groups in daily activity sheets. Neither demographics nor the CDSI or the CHQ scores significantly differed between the 2 groups. Step counts of children with clubfoot with or without relapse were similar to published levels for healthy children. CONCLUSION: Children with clubfoot initially treated with the Ponseti method who undergo treatment for relapse have comparable physical activity to those who have not relapsed. They also have comparable step counts to that of the general pediatric population. These reassuring findings can guide conversations with parents when addressing concerns regarding their children's physical activity after treatment for relapse of clubfoot deformity. LEVEL OF EVIDENCE: Level II-therapeutic studies-investigating the results of treatment.

Use of Bedside Entertainment and Relaxation Theater (BERT) to Reduce Fear and Anxiety Associated With Outpatient Procedures in Pediatric Orthopaedics.

BACKGROUND: The aim of the present study was to evaluate the effectiveness of the Bedside Entertainment and Relaxation Theater (BERT) on fear, anxiety, and pain outcomes in pediatric orthopaedic patients associated with cast removal and/or pin removal in the outpatient clinic setting. METHODS: A total of 66 pediatric patients between the ages of 2 and 6 undergoing clinic procedures were recruited for this study and randomized into the control group or the intervention (BERT) group. Patients in the control group received standard of care during the cast room procedure; patients in the BERT group were given headphones and watched a movie on a projector during the procedure. Fear, anxiety, and pain were measured before and after the procedure. Procedures included cast removal, pin removal, or a combination of the 2. RESULTS: Patients in the BERT group reported less fear and anxiety overall after the procedure than patients in the control group (P=0.009, 0.015). Adjusting for procedure type (ie, pin removal), patients in the BERT group reported a 0.67 point decrease (95% confidence interval: 0.04, 1.30) on the fear scale after the procedure (P=0.039) and a 1.81 point decrease (95% confidence interval: 0.04, 3.59) on the anxiety scale associated with the procedure (P=0.045), compared with the control group. Patients and caregivers reported high satisfaction with BERT. CONCLUSION: This randomized, controlled trial demonstrates an evidence-based distraction tool that can be implemented across medical centers for pediatric patients undergoing office based orthopaedic procedures. BERT can be used to reduce fear and anxiety associated with these procedures, and increase patient and parent satisfaction. LEVEL OF EVIDENCE: Level I.

Virtual Reality Reduces Fear and Anxiety During Pediatric Orthopaedic Cast Room Procedures: A Randomized Controlled Trial.

BACKGROUND: Virtual Reality (VR) has been used as a distraction tool in various medical settings to reduce pain and anxiety associated with procedures. This study evaluates the effectiveness of VR as a distraction tool for decreasing fear, anxiety, and pain in pediatric patients undergoing common outpatient orthopaedic procedures. METHODS: A total of 210 patients were recruited from a single orthopaedic clinic between October 2017 and July 2019. Patients were randomized to the VR group or to the control group (standard of care). Outpatient procedures included cast and/or pin removals. Primary outcome measures were collected preprocedure and postprocedure using validated surveys, and included: fear (Children's Fear Scale), anxiety (Children's Anxiety Meter-State), and pain (Numerical Rating Scale). Patients and caregivers in the VR group completed a satisfaction survey at the end of their appointment. Fear, anxiety, and pain scores between the 2 groups were analyzed using multivariable linear regression models, and the satisfaction survey was analyzed using descriptive statistics. RESULTS: One hundred twenty nine patients were included in the final analysis, with 85 patients in the VR group and 44 patients in the control group. During the procedure, patients in the VR group reported significantly lower average fear scores ( P <0.001) and anxiety scores ( P =0.003) as compared with controls. There were no differences between the groups in fear and anxiety scores before and after the procedure, or pain scores before, during, or after the procedure. Overall, patients and caregivers in the VR group reported high satisfaction scores, with 97% of patients and 95% of caregivers recommending this intervention to others. CONCLUSION: VR technology was found to be an effective distraction tool to improve fear and anxiety during cast removal procedures. Findings build on a body of evidence that supports the use of distraction tools in clinics, specifically pediatric orthopaedics, to improve fear and anxiety. The distraction tools can be easily translated into current practices. LEVEL OF EVIDENCE: Level I.

Dynamic Supination in Congenital Clubfoot: A Modified Delphi Panel Approach to Standardizing Definitions and Indications for Treatment.

BACKGROUND: Dynamic supination is a well-recognized cause of congenital clubfoot deformity relapse. However, there is no consensus on how to diagnose it and there are varied approaches in its management. This study aims to define dynamic supination and indications for treatment by presenting consensus from an international panel of experts using a modified Delphi panel approach. METHODS: An international panel of 15 pediatric orthopaedic surgeons with clinical and research expertise in childhood foot disorders participated in a modified Delphi panel on dynamic supination in congenital clubfoot. Panelists voted on 51 statements using a 4-point Likert scale on dynamic supination, clinical indications for treatment, operative techniques, and postoperative casting and bracing. All panelists participated in 2 voting rounds with an interim meeting for discussion. Responses were classified as unanimous consensus (100%), consensus (80% or above), near-consensus (70% to 79%), and indeterminate (69% or less). RESULTS: Consensus was achieved for 34 of 51 statements. Panelists agreed dynamic supination is present when the forefoot is supinated during swing phase of gait with initial contact on the lateral border of the foot. There was also agreement that dynamic supination results from muscle imbalance between the tibialis anterior and the peroneus longus and brevis. There was no consensus on observation of hindfoot varus in dynamic supination, operative indications for posterior release of the ankle joint, or incisional approach for tibialis anterior tendon transfer. Reference to the calcaneopedal unit concept, planes of movement, and phases of gait were deemed important factors for consideration when evaluating dynamic supination. CONCLUSIONS: Consensus statements from the Delphi panel can guide diagnosis and treatment of dynamic supination in clubfoot deformity relapse, including clinical decision making regarding preoperative casting, surgical approach, and postoperative immobilization. Near-consensus and indeterminate statements may be used to direct future areas of investigation. LEVEL OF EVIDENCE: Level V.

Is Grit Associated with Burnout and Well-being in Orthopaedic Resident and Faculty Physicians? A Multi-institution Longitudinal Study Across Training Levels.

BACKGROUND: Grit has been defined as "perseverance and passion for long-term goals" and is characterized by maintaining focus and motivation toward a challenging ambition despite setbacks. There are limited data on the impact of grit on burnout and psychologic well-being in orthopaedic surgery, as well as on which factors may be associated with these variables. QUESTIONS/PURPOSES: (1) Is grit inversely correlated with burnout in orthopaedic resident and faculty physicians? (2) Is grit positively correlated with psychologic well-being in orthopaedic resident and faculty physicians? (3) Which demographic characteristics are associated with grit in orthopaedic resident and faculty physicians? (4) Which demographic characteristics are associated with burnout and psychologic well-being in orthopaedic resident and faculty physicians? METHODS: This study was an institutional review board-approved interim analysis from the first year of a 5-year longitudinal study of grit, burnout, and psychologic well-being in order to assess baseline relationships between these variables before analyzing how they may change over time. Orthopaedic residents, fellows, and faculty from 14 academic medical centers were enrolled, and 30% (335 of 1129) responded. We analyzed for the potential of response bias and found no important differences between sites in low versus high response rates, nor between early and late responders. Participants completed an email-based survey consisting of the Duckworth Short Grit Scale, Maslach Burnout Inventory-Human Services (Medical Personnel) Survey, and Dupuy Psychological Well-being Index. The Short Grit Scale has been validated with regard to internal consistency, consensual and predictive validity, and test-retest stability. The Psychological Well-being Index has similarly been validated with regard to reliability, test-retest stability, and internal consistency, and the Maslach Burnout Inventory has been validated with regard to internal consistency, reliability, test-retest stability, and convergent validity. The survey also obtained basic demographic information such as survey participants' age, gender, race, ethnicity, marital status, current year of training or year in practice (as applicable), and region of practice. The studied population consisted of 166 faculty, 150 residents, and 19 fellows. Beyond the expected age differences between sub-populations, the fellow population had a higher proportion of women than the faculty and resident populations did. Pearson correlations and standardized ß coefficients were used to assess the relationships of grit, burnout, psychologic well-being, and continuous participant characteristics. RESULTS: We found moderate, negative relationships between grit and emotional exhaustion (r = -0.30; 95% CI -0.38 to -0.21; p < 0.001), depersonalization (r = -0.34; 95% CI -0.44 to -0.23; p < 0.001), and the overall burnout score (r = -0.39; 95% CI -0.48 to -0.31; p < 0.001). The results also showed a positive correlation between grit and personal accomplishment (r = 0.39; 95% CI 0.29 to 0.48; p < 0.001). We also found a moderate, positive relationship between grit and psychologic well-being (r = 0.39; 95% CI 0.30 to 0.49; p < 0.001). Orthopaedic surgeons with 21 years or more of practice had higher grit scores than physicians with 10 to 20 years of practice. Orthopaedic surgeons in practice for 21 years or more also had lower burnout scores than those in practice for 10 to 20 years. Married physicians had higher psychologic well-being than unmarried physicians did. CONCLUSION: Among orthopaedic residents, fellows, and faculty, grit is inversely related to burnout, with lower scores for emotional exhaustion and depersonalization and higher scores for personal accomplishment as grit increases. CLINICAL RELEVANCE: The results suggest that grit could be targeted as an intervention for reducing burnout and promoting psychologic well-being among orthopaedic surgeons. Other research has suggested that grit is influenced by internal characteristics, life experiences, and the external environment, suggesting that there is potential to increase one's grit. Residency programs and faculty development initiatives might consider measuring grit to assess for the risk of burnout, as well as offering curricula or training to promote this psychologic characteristic.

Deciding without data: clinical decision-making in pediatric orthopedic surgery.

OBJECTIVE: Identifying when and how often decisions are made based on high-quality evidence can inform the development of evidence-based treatment plans and care pathways, which have been shown to improve quality of care and patient safety. Evidence to guide decision-making, national guidelines and clinical pathways for many conditions in pediatric orthopedic surgery are limited. This study investigated decision-making rationale and quantified the evidence supporting decisions made by pediatric orthopedic surgeons in an outpatient clinic. DESIGN/SETTING/PARTICIPANTS/INTERVENTION(S)/MAIN OUTCOME MEASURE(S): We recorded decisions made by eight pediatric orthopedic surgeons in an outpatient clinic and the surgeon's reported rationale behind the decisions. Surgeons categorized the rationale for each decision as one or a combination of 12 possibilities (e.g. 'Experience/anecdote,' 'First principles,' 'Trained to do it,' 'Arbitrary/instinct,' 'General study,' 'Specific study'). RESULTS: Out of 1150 total decisions, the most frequent decisions were follow-up scheduling, followed by bracing prescription/removal. The most common decision rationales were 'First principles' (n = 310, 27.0%) and 'Experience/anecdote' (n = 253, 22.0%). Only 17.8% of decisions were attributed to scientific studies, with 7.3% based on studies specific to the decision. As high as 34.6% of surgical intervention decisions were based on scientific studies, while only 10.4% of follow-up scheduling decisions were made with studies in mind. Decision category was significantly associated with a basis in scientific studies: surgical intervention and medication prescription decisions were more likely to be based on scientific studies than all other decisions. CONCLUSIONS: With increasing emphasis on high value, evidence-based care, understanding the rationale behind physician decision-making can educate physicians, identify common decisions without supporting evidence and help create clinical care pathways in pediatric orthopedic surgery. Decisions based on evidence or consensus between surgeons can inform pathways and national guidelines that minimize unwarranted variation in care and waste. Decision support tools and aids could also be implemented to guide these decisions.

Surveying the POSNA Landscape: What Can We Learn From Society Survey Studies?

BACKGROUND: A growing trend of survey-based research has been seen in the field of pediatric orthopaedics. The purpose of this study was to describe patterns of surveys of Pediatric Orthopaedic Society of North America (POSNA) membership and evaluate for associations between study characteristics and response rates in order to inform future research efforts. We hypothesized that studies with fewer survey questions and study group or committee involvement would demonstrate higher response rates. METHODS: A systematic review of the literature was performed to identify all peer-reviewed survey publications targeting POSNA members published up to December 2017. Included studies were reviewed to identify author and publication characteristics, survey development and methodology, survey distribution procedures, and response rates. Statistical analyses were performed to describe publication patterns and evaluate for associations between study characteristics and response rates. RESULTS: Thirty-four studies published from 1991 to 2017 were identified as meeting inclusion criteria, with a substantial increase noted over the last 3 years. Studies included 4.6 (SD 1.9) authors and 14.7% had affiliations with study groups or committees. Survey development methodology was detailed in only 1 study. Surveys included a median of 19.5 questions (3 to 108) and were primarily electronically distributed. The mean survey response rate was 42% with a downward trend noted over the studied time period. None of the studied author, publication, and design characteristics were associated with increased response rates. CONCLUSIONS: Survey-based studies of the POSNA membership have become increasingly popular study designs in recent years. Response rates are lower than reports in other physician cohorts, and appear to be declining, possibly representative of respondent fatigue. No associations were identified between response rates and the modifiable study characteristics evaluated (number of authors, committee or subgroup affiliation, number of questions, and mode of distribution). Efforts should be made to identify tactics to sustain participation as these studies become more widely utilized within our field. Optimizing study design and implementation features while valuing physician time and effort spent on survey completion is important to avoid member survey fatigue.

Restoration of Blood Flow to the Proximal Femoral Epiphysis in Unstable Slipped Capital Femoral Epiphysis by Modified Dunn Procedure: A Preliminary Angiographic and Intracranial Pressure Monitoring Study.

BACKGROUND: The major complication of unstable slipped capital femoral epiphysis (SCFE) is avascular necrosis (AVN) of the femoral head. The purpose of this study was to document by angiography the preoperative and postoperative perfusion to the proximal femoral epiphysis following an unstable SCFE. A specific aim was to determine whether blood flow could be restored. A secondary aim was to determine the efficacy of an intracranial pressure (ICP) monitor to assess blood flow within the femoral head intraoperatively. METHODS: Nine patients with an unstable SCFE underwent superselective angiogram of the medial circumflex femoral artery preoperatively, followed by operative fixation with an open reduction using a modified Dunn approach. Femoral head blood flow was evaluated with an ICP monitor. Angiography was repeated postoperatively. Patients were followed radiographically to assess for AVN. RESULTS: Follow-up averaged 22 months. Six patients did not have arterial flow to the femoral head on the preoperative angiogram. Flow was restored postoperatively on angiogram in 4 of the 6 patients. Two patients developed AVN. One had no flow to the femoral head preoperatively or postoperatively on angiogram and complete tearing of the periosteum was noted. In 1 patient, there was no ICP waveform after the initial reduction. After removing more callous and repeating reduction, the waveform returned. Of the 2 patients with AVN, 1 had an ICP waveform after reduction. CONCLUSIONS: This study documents that some patients with unstable SCFE present with reduced femoral head blood supply due to SCFE. It also demonstrates blood flow restoration in 4 patients by angiogram and 5 by ICP monitor after surgical treatment. No patient immediately lost blood flow due to surgery. ICP monitor is a safe intraoperative tool for real-time assessment of femoral head blood flow during open reduction of unstable SCFE. Presence of flow by ICP is not a guarantee that AVN will not develop, but absence of flow was predictive of AVN. LEVEL OF EVIDENCE: Therapeutic level I-prognostic.

Intra-Operative Bone Stability Test.

Fractures of the supercondylar humerus are the most common elbow fracture in pediatrics. Management of this injury would be aided if surgeons could reliably test fracture stability intraoperatively after pinning. A transverse supracondylar humerus fracture model was created using 3 adult cadaver upper-extremity specimens with an intact soft tissue envelope. Using the lateral entry technique, three 2.0 mm pins were then drilled using lateral entry technique to create an "A" pinning. Pins were checked in anteroposterior and lateral views with the C-arm to confirm accurate placement in both planes. The pinning configuration was then tested by holding the proximal fragment steady with one hand and applying stress to the distal fragment with the other hand. The amount of movement of the distal fragment relative to the proximal fragment was recorded for each specimen. Distraction did not produce any substantial displacement of the osteotomy. The most valuable maneuvers were (in order of effectiveness): external rotation, lateral translation, posterior translation, valgus, and apex posterior. The results of this study indicate that external rotation, lateral translation, posterior translation, and valgus stresses created the most temporary deformity to the construct. A combination of these maneuvers should help the surgeon to decide if the fixation is stable. Our study demonstrates a possible technique to determining intraoperatively the stability of fixation of supracondylar humerus fractures, which could prevent the need for postoperative radiographs to assess stability.

Assessing Quality and Safety in Pediatric Supracondylar Humerus Fracture Care.

BACKGROUND: Recently, there has been an emphasis on improving quality, safety, and value in the delivery of health care in the United States. The American Board of Orthopedic Surgery (ABOS) has developed a performance improvement questionnaire (PIQ) for orthopaedic surgeons managing pediatric supracondylar humerus fracture (PSCHF). Using the supracondylar PIQ as a guide, this study evaluates the process of measuring the outcomes and variations in care to PSCHF patients among pediatric orthopaedic surgeons. METHODS: An 88-question survey incorporating the ABOS PIQ was administered to 35 pediatric orthopaedic surgeons at 3 institutions. A retrospective chart review of patients who received operative management of a PSCHF during 2013 was performed. Each of the 17 eligible surgeons supplied 5 patients for a total of 85 patients. Medical records and radiographic imaging were reviewed using the ABOS PIQ data collection sheet. This data collection sheet encompasses the preoperative assessment, intraoperative treatment and assessment, and clinical and radiographic outcomes of patients with PSCHF. RESULTS: A total of 35 surgeons from 6 hospitals completed the online PSCHF survey. Uniform consensus among all 35 surgeons was identified in 21/79 of the questions (27%). Consensus among surgeons within a hospital group but not with surgeons from the other groups was identified in 39/79 (49%) of the questions. No consensus among the surveyed surgeons could be identified in 19/79 (24%) of the questions. For the 85 PSCHF patients the average age was 6 years, and 37% of fractures were type II, 57% of fractures were type III, and there was 1 flexion type. Ninety percent of the patients received a preoperative dose of antibiotics and the postoperative immobilization placed in the operating room was changed in the clinic before pin removal in 58% of the cases. Pins were removed at 3 weeks in 60%, 4 weeks in 30%, 5 weeks in 7%, and after 5 weeks in 3% of the patients and no malunions occurred. Pin tract infection occurred in 2 patients (2.4%). The procedure time ranged from 13 to 171 minutes, with a median time of 37 minutes. Total anesthesia time ranged from 32 to 233 minutes, with a median of 72 minutes. The number of outpatient follow-up visits ranged from 2 to 7 visits, with a median of 3 visits. The number of postoperative radiographs obtained ranged from 1 to 14, with a median of 3 studies. Four patients (5%) returned to the operating room for a repeat surgery. CONCLUSIONS: The survey responses from the surgeons at 6 different hospitals demonstrate that there is still considerable variation in care among surgeons, even for such a routine injury. Our chart review also revealed substantial variation in care with subsequent quality and cost-implications. The variations in operating room time, anesthesiology time, number of postoperative visits, number of radiographs ordered, and the initial intraoperative immobilization, all point to opportunities for standardization and lowering of costs.

Adolescent Distal Humerus Fractures: ORIF Versus CRPP.

BACKGROUND: Although supracondylar humerus fractures are common in young children, the incidence in adolescents is much lower. As a result, there is a paucity of literature to guide treatment. The purpose of this study was to review the treatment and outcomes for a consecutive series of distal humerus fractures in adolescents and to compare outcomes between patients treated with percutaneous skeletal fixation and those treated with open reduction and fixation. METHODS: A retrospective review of patients 10 to 17 years of age who underwent surgical treatment for a distal humerus fracture from 2005 to 2014 was performed. Patients with medial epicondyle fractures and those with insufficient follow-up to document union or return of motion were excluded. Medical records were reviewed to collect demographic data as well as operative approach and method of fixation. Clinical outcomes included range of motion, time to maximum motion, and complications [nerve dysfunction, heterotopic ossification (HO), need for secondary surgery]. Radiographs were reviewed to determine time to union as well as coronal and sagittal alignment. RESULTS: One hundred eighteen adolescents with displaced distal humerus fractures were identified. Eighty-one met inclusion criteria. Forty-four of these were classified as extra-articular [Orthopaedic Trauma Association (OTA) 13-A], and 37 were intra-articular fractures (10 OTA 13-B and 27 OTA 13-C).Although not statistically significant, closed treatment with percutaneous fixation of extra-articular fractures resulted in greater flexion-extension arc of motion at final follow-up (128 vs. 119 degrees, P=0.17) and demonstrated more rapid return of motion (2.8 vs. 3.9 mo, P=0.05) when compared with open treatment despite a longer duration of immobilization and less formal physical therapy. Complications such as HO (P=0.05), nerve dysfunction (P=0.02), and secondary surgery (P=0.001) were more common in the open treatment group.Closed treatment with percutaneous fixation of intra-articular fractures was performed in younger patients of similar size (12.8 vs. 14.4 y, P<0.01; 154 vs. 142 lbs, P=0.5). There were no significant differences between groups in regard to outcomes or complications. There were trends toward increased frequency of HO, nerve dysfunction, and secondary surgery in the open treatment group.Patients with intra-articular fractures were older (14.2 vs. 11.5 y, P<0.001) and heavier (144 vs. 94 lbs, P<0.001) than patients with extra-articular fractures and were more likely to be treated open (74% vs. 11%, P<0.001). Extra-articular fractures demonstrated a greater total arc of motion (126 vs. 118 degrees, P=0.04) at final follow-up despite longer duration of immobilization (23 vs. 15 d, P=0.002), and less physical therapy (27% vs. 73%, P<0.001). Radiographic carrying angle (16.6 vs. 22.3 degrees, P=0.08) and anterior humeral line (95% vs. 81%, P=0.07) trended toward more anatomic alignment in the extra-articular group. Secondary surgery was more common after intra-articular fracture (24% vs. 7%, P=0.03). CONCLUSIONS: Closed reduction and pinning of extra-articular distal humerus fractures in adolescents resulted in predictable clinical and radiographic outcomes and allowed for earlier return of motion and fewer complications when compared with open treatment. Intra-articular distal humerus fractures occur more frequently in older adolescents and are more likely to require open reduction and internal fixation to obtain joint congruity. Patients with intra-articular injuries should be cautioned that regaining full elbow motion may be more difficult, and there is an increased risk for complications and need for additional surgery. Closed reduction and percutaneous fixation of intra-articular injuries appears to be a reasonable option in select patients. LEVEL OF EVIDENCE: Level III-retrospective comparative study.

An Inclusive Analysis of Racial and Ethnic Disparities in Orthopedic Surgery Outcomes.

BACKGROUND: Despite increasing attention, disparities in outcomes for Black and Hispanic patients undergoing orthopedic surgery are widening. In other racial-ethnic minority groups, outcomes often go unreported. We sought to quantify disparities in surgical outcomes among Asian, American Indian or Alaskan Native, and Native Hawaiian or Pacific Islander patients across multiple orthopedic subspecialties. MATERIALS AND METHODS: The National Surgical Quality Improvement Program was queried to identify all surgical procedures performed by an orthopedic surgeon from 2014 to 2020. Multivariable logistic regression models were used to investigate the impact of race and ethnicity on 30-day medical complications, readmission, reoperation, and mortality, while adjusting for orthopedic subspecialty and patient characteristics. RESULTS: Across 1,512,480 orthopedic procedures, all patients who were not White were less likely to have arthroplasty-related procedures (P<.001), and Hispanic, Asian, and American Indian or Alaskan Native patients were more likely to have trauma-related procedures (P<.001). American Indian or Alaskan Native (adjusted odds ratio [AOR], 1.005; 95% CI, 1.001-1.009; P=.011) and Native Hawaiian or Pacific Islander (AOR, 1.009; 95% CI, 1.005-1.014; P<.001) patients had higher odds of major medical complications compared with White patients. American Indian or Alaskan Native patients had higher risk of reoperation (AOR, 1.005; 95% CI, 1.002-1.008; P=.002) and Native Hawaiian or Pacific Islander patients had higher odds of mortality (AOR, 1.003; 95% CI, 1.000-1.005; P=.019) compared with White patients. CONCLUSION: Disparities regarding surgical outcome and utilization rates persist across orthopedic surgery. American Indian or Alaskan Native and Native Hawaiian or Pacific Islander patients, who are under-represented in research, have lower rates of arthroplasty but higher odds of medical complication, reoperation, and mortality. This study highlights the importance of including these patients in orthopedic research to affect policy-related discussions. [Orthopedics. 2024;47(3):e131-e138.].

Strengthening the Pipeline: Promoting Diversity into Orthopedic Surgery.

The United States is a nation of diverse racial and ethnic origins. Athletes represent the full spectrum of the nation's population. However, the orthopedic surgeons who serve as team physicians are Caucasian and male with staggeringly few exceptions. This manuscript provides an overview of the current status and barriers to diversity among orthopedic team physicians, along with strategies to address the issue. Specifically, pipeline initiatives implemented at one academic medical school and orthopedic surgery department are summarized as potential models that can be further developed by other institutions to enhance diversity in orthopedic surgery.

Parental Concerns Regarding Bracing Compliance for Children With Clubfoot: Seeking Support on Facebook.

Background Clubfoot treatment requires a period of bracing until early childhood to maintain the initial correction achieved by Ponseti casting and serial manipulations. During this period, bracing compliance is the most important factor in preventing the relapse of clubfoot deformity. This period can be challenging for parents, given several factors that affect treatment adherence. In recent years, social media has opened up new ways to seek guidance from an online community, including health-focused areas such as congenital clubfoot. This study examines bracing-related concerns that arise during clubfoot treatment that lead caregivers to seek support from online forums like Facebook. Methodology Six Facebook clubfoot support groups with the highest number of clubfoot posts were evaluated to identify the relative proportion and content of posts related to bracing compliance during December 2021. Bracing-related concerns across all identified posts were then organized into the following six domains that may affect the child's bracing adherence: physical, psychological, commercial, social, bracing device-related, and parental. Results In December 2021, there were 442 total posts across the six clubfoot-focused Facebook groups analyzed. Of these, 23.1% of posts were directly related to bracing compliance. Approximately 22% of these posts had responses where at least one fellow parent suggested seeking advice from a healthcare professional. When these root concerns were organized into six domains that can affect the child's bracing compliance, we found 49 physical, 26 psychological, 5 commercial, 0 social, 14 bracing device-related, and 8 parental factors. Conclusions In this study, 23.1% of all analyzed Facebook posts involved discussion about brace-related concerns, making this a significant topic of discussion on online parental forums. Facebook groups create a community and provide emotional support to parents that support bracing compliance. Clubfoot physicians should be aware of key parental concerns related to bracing compliance, and physicians can provide education on bracing that provides accurate information and anticipatory counseling during regular check-ups with patients and their families.

AP Radiographic Assessment of the Pediatric Pelvis for Developmental Dysplasia of the Hip.

Mastering the art of roentgenographic analysis of the pediatric AP pelvis is paramount in the evaluation of developmental dysplasia of the hip. Understanding the normal radiographic development and the age-dependent changes in normal values allows assessment for pathologic changes. The goal of improving the analysis of the AP pelvis is to increase early detection of disease, assess progress toward normal values, and precisely follow the effects of treatment to improve clinical outcomes.

Tibialis Anterior and Posterior Tendon Transfer for Clubfoot Relapse in a Child with Duchenne Muscular Dystrophy: A Case Report.

CASE: A boy with bilateral congenital clubfoot, Kleefstra syndrome, and Duchenne muscular dystrophy (DMD) developed clubfoot relapse after excellent initial correction with the Ponseti method and maintenance abduction bracing. A traditional clubfoot tibialis anterior transfer was augmented with a tibialis posterior tendon transfer, given underlying DMD at ages 7 and 10 years for the right foot and left foot, respectively. CONCLUSION: This case illustrates successful maintenance of correction using combined tibialis anterior and tibialis posterior tendon transfer. Tibialis posterior tendon transfer may be useful for clubfoot relapse in conditions that weaken the tibialis anterior or in failed tibialis anterior tendon transfers.

Idiopathic Toe-Walking in Children and Adolescents: Diagnosis, Natural History, and Treatment Options.

¼: Idiopathic toe-walking is a diagnosis of exclusion. ¼: The natural history of idiopathic toe-walking has not been studied in many children; we identified only 1 prospective study. Of children without equinus contractures who were toe-walking before the age of 5.5 years, 59% had spontaneous resolution of toe-walking by 5.5 years of age, and 79%, by the age of 10 years. ¼: Adverse consequences of toe-walking into adulthood have not been reported, but may exist, and further research is needed to define and clarify. ¼: If parents desire treatment to resolve their child's toe-walking, surgical lengthening of the Achilles tendon is the treatment with the highest chance of success and lowest relapse rate, and thus far, no complications have been reported in any surgical series.

The Axillary Nerve Danger Zone in Percutaneous Fixation in the Pediatric Shoulder: The "1-Mountain-3-Valleys" Principle.

BACKGROUND: Adult literature cites an axillary nerve danger zone of 5 to 7 cm distal to the acromion tip for open or percutaneous shoulder surgery, but that may not be valid for younger patients. This study sought to quantify the course of the axillary nerve in adolescent patients with reference to easily identifiable intraoperative anatomic and radiographic parameters. METHODS: A single-institution hospital database was reviewed for shoulder magnetic resonance images (MRIs) in patients 10 to 17 years old. One hundred and one MRIs from patients with a mean age of 15.6 ± 1.2 years (range, 10 to 17 years) were included. Axillary nerve branches were identified in the coronal plane as they passed lateral to the proximal humerus and were measured in relation to identifiable intraoperative surface and radiographic landmarks, including the acromion tip, apex of the humeral head, lateral physis, and central apex of the physis. The physeal apex height (i.e., 1 "mountain") was defined as the vertical distance between the most lateral point of the humeral physis (LPHP) and the central intraosseous apex of the physis. RESULTS: Axillary nerve branches were found in all specimens, adjacent to the lateral cortex of the proximal humerus. A mean of 3.7 branches (range, 2 to 6) were found. The mean distance from the most proximal branch (BR1) to the most distal branch (BR2) was 11.7 mm. The pediatric danger zone for the axillary nerve branches ranged from 6.6 mm proximal to 33.1 mm distal to the LPHP. The danger zone in relation to percent of physeal apex height included from 62% proximal to 242% distal to the LPHP. CONCLUSIONS: All branches were found distal to the apex of the physis (1 "mountain" height proximal to the LPHP). Distal to the LPHP, no branches were found beyond a distance of 3 times the physeal apex height (3 "valleys"). In children and adolescents, percutaneous fixation of the proximal humerus should be performed with cortical penetration outside of this range. These parameters serve as readily identifiable intraoperative radiographic landmarks to minimize iatrogenic nerve injury. CLINICAL RELEVANCE: This study provides valuable landmarks for percutaneous approaches to the proximal humerus. The surgical approach for the placement of percutaneous implants should be adjusted accordingly (i.e., performed at least 1 mountain proximal or 3 valleys distal to the LPHP) in order to prevent iatrogenic injury to the axillary nerve.
