Hazard of Failed Nonoperative Management for Symptomatic Accessory Navicular in Children and Adolescents: A Population-Based Case-Cohort Study.

BACKGROUND: The accessory navicular (AN) is an idiopathic condition of the foot present in 4% to 21% of the population. Most ANs remain asymptomatic, but children and adolescents who develop symptoms can have remarkably reduced quality of life. Although many respond to conservative measures, surgery is occasionally needed. Our purpose was to determine factors associated with the failure of nonoperative management. METHODS: This single-institution retrospective case-cohort study included patients up to age 19 years presenting between 2000 and 2021 with symptomatic AN and treated with standard-of-care. All 298 surgical cases, indicating failed nonoperative treatment, were included. For the subcohort, 299 patients were randomly sampled from all eligible patients, regardless of treatment. Baseline characteristics were summarized for the surgical cases and subcohort. Proportional hazards assumptions were checked and stratification implemented when necessary. Marginal structural proportional hazard modeling was used to estimate hazard ratios with 95% confidence intervals via inverse probability and LinYing weighting methods. RESULTS: The 298 surgical cases failed nonoperative management at a median of 5.2 months (IQR, 2.0-11.6 mo). In the subcohort, 86 failures of nonoperative management and 213 nonfailures constituted a 28.8% surgery rate. In both cohorts, nearly all patients played sports. Univariate proportional hazard modeling found older age (P=0.02) and activity limitation (P<0.001) at presentation, female sex (P=0.002), higher BMI (P=0.01), AN on the right (P<0.001), and bone marrow edema of the AN (P<0.001) and navicular body (P<0.001) on MRI were associated with increased hazard of nonoperative failure. Nearly all of the surgical cohort reported improvement in pain (278/296, 94%) and returned to their primary sport (236/253, 93%) after surgery. Most also experienced full resolution of symptoms (187/281, 67%). CONCLUSIONS: Symptomatic AN predominantly affects female athletes, leading to surgery in 28.8% of our subcohort. Conservative treatment may be less successful-and therefore surgery could be more strongly considered-in older age, activity limitation at presentation, female sex, higher BMI, right-sided AN, and bone marrow edema on MRI. Surgery is effective for symptomatic and functional improvement. LEVEL OF EVIDENCE: Case-cohort-Level III.

Descriptive Epidemiology of Isolated Distal Radius Fractures in Children: Results From a Prospective Multicenter Registry.

INTRODUCTION: More than 1 in 4 pediatric fractures involves the distal radius. Most prior epidemiologic studies are limited to retrospective, single center investigations, and often include adults. This study aims to describe the contemporary epidemiology of pediatric distal radius fractures using prospectively collected data from a multicenter Pediatric Distal Radius Fracture Registry. METHODS: Patients aged 4 to 18 years diagnosed with a distal radius fracture from June 2018 through December 2019 at 4 tertiary care pediatric centers were screened and enrolled in this prospective longitudinal cohort study. Patients were excluded if they presented with bilateral distal radius fractures, polytrauma, or re-fracture. Demographic information, mechanism of injury, fracture characteristics, associated injuries, and procedural information were recorded. All radiographs were reviewed and measured. Descriptive statistics and bivariate analyses were performed. RESULTS: A total of 1951 patients were included. The mean age was 9.9±3.3 years, and 61.3% of patients were male ( P <0.001). Most injuries occurred during a high-energy fall (33.5%) or sports participation (28.4%). The greatest proportion of fractures occurred during the spring months (38.5%). Torus fractures (44.0%) were more common than bicortical (31.3%) or physeal (21.0%) fractures. Of the physeal fractures, 84.3% were Salter-Harris type II. Associated ulnar fractures were observed in 51.2% of patients. The mean age at injury was higher for patients with physeal fractures (11.6±2.9 y) than patients with torus or bicortical fractures (9.4±3.1 and 9.6±3.1 y, respectively; P <0.001). Thirty-six percent of distal radius fractures underwent closed reduction and 3.3% underwent surgical fixation. Patients treated with closed reduction were more likely to be male (68.7% vs. 57.2%; P <0.001), obese (25.3% vs. 17.2%; P <0.001), and have bicortical fractures (62.2% vs. 14.5%; P <0.001). CONCLUSIONS: Distal radius fractures in children have a male preponderance and are most likely to occur in the spring months and during high-energy falls and sports. Physeal fractures tend to occur in older children while torus and bicortical fractures tend to occur in younger children. LEVEL OF EVIDENCE: Level I-prognostic.

Fully displaced pediatric supracondylar humerus fractures: Which ones need to go at night?

Background: Challenges remain in determining which displaced supracondylar humerus fractures are safe to postpone surgical treatment until daylight hours. The purpose of this study is to determine which characteristics can be identified to guide the timing of treatment of supracondylar humerus fractures. Methods: 225 completely displaced Gartland extension type 3/4 supracondylar humerus fractures in healthy patients that presented between 6 am and 7 am were identified. Data were collected retrospectively. Data analysis included univariate, multivariable logistic regression and classification and regression tree analysis. Results: 5% (78/225) underwent surgical treatment the night they presented, while 65% (147/225) were treated the next day. Overall complication rate was 6%, with no difference based on timing of surgery. 12% (28/225) presented with a motor nerve injury, while 6% (14/225) a "pink pulseless" extremity. Statistical analysis found the most reliable radiographic predictor to be the maximum displacement on the anterior-posterior or lateral view. Classification and regression tree analysis developed a clinical algorithm; patients with a "pink pulseless" extremity or motor nerve injury were recommended for surgery overnight, while those with an anterior-posterior or lateral view < 25 mm were recommended for surgery the next day. Conclusion: This study provides guidance on the timing of treatment for displaced supracondylar humerus fractures that present overnight. We provide a simple algorithm with three key clinical predictors for timing of treatment: presence of a "pink pulseless" arm, presence of a motor nerve injury, and displacement of any cortex by at least 25 mm (anterior-posterior or lateral view). This provides a step forward to help practitioners make safer evidenced-based timing decisions for their patients. Level of evidence: Prognostic Study, Level II.

Standardizing Opioid Prescribing in a Pediatric Hospital: A Quality Improvement Effort.

BACKGROUND: Opioids are indicated for moderate-to-severe pain caused by trauma, ischemia, surgery, cancer and sickle cell disease, and vaso-occlusive episodes (SCD-VOC). There is only limited evidence regarding the appropriate number of doses to prescribe for specific indications. Therefore, we developed and implemented an opioid prescribing algorithm with dosing guidelines for specific procedures and conditions. We aimed to reach and sustain 90% compliance within 1 year of implementation. METHODS: We conducted this quality improvement effort at a pediatric academic quaternary care institution. In 2018, a multidisciplinary team identified the need for a standard approach to opioid prescribing. The algorithm guides prescribers to evaluate the medical history, physical examination, red flags, pain type, and to initiate opioid-sparing interventions before prescribing opioids. Opioid prescriptions written between January 2015 and September 2020 were included. Examples from 2 hospital departments will be highlighted. Control charts for compliance with guidelines and variability in the doses prescribed are presented for selected procedures and conditions. RESULTS: Over 5 years, 83 037 opioid prescriptions in 53 804 unique patients were entered electronically. The encounters with ≥1 opioid prescription decreased from 48% to 25% between 2015 and 2019. Compliance with the specific guidelines increased to ∼85% for periacetabular osteotomies and SCD-VOC and close to 100% for anterior-cruciate ligament surgery. In all 3 procedures and conditions, variability in the number of doses prescribed decreased significantly. CONCLUSION: We developed an algorithm, guidelines, and a process for improvement. The number of opioid prescriptions and variability in opioid prescribing decreased. Future evaluation of specific initiatives within departments is needed.

Retrospective study of patterns of vitamin D testing and status at a single institution paediatric orthopaedics and sports clinics.

OBJECTIVES: There has been a recent increase in awareness of the importance of bone health in children treated by paediatric orthopaedic and sports medicine providers. The purpose of this study was to assess our utilisation of 25 hydroxy vitamin D (25(OH)Vit D) testing in the past 10 years, and to evaluate the level of 25(OH)Vit D sufficiency in various populations of patients seen. DESIGN: This is a single site, retrospective medical record review study. SETTING: The study took place at a single large, private, paediatric level 1 trauma teaching hospital in the Northeast USA. PARTICIPANTS: Our internal medical records query system identified all patients who have had 25(OH)Vit D testing in the past 10 years, from 1 January 2009 to 31 December 2018. All patients included were seen on an outpatient basis at our Orthopaedic clinics. INTERVENTIONS: No interventions for strict research, however, eligible patients have had 25(OH)Vit D testing during their standard of care treatment. MAIN OUTCOME MEASURES: The varying number of 25(OH)Vit D testing that occurred over the study time period within Orthopaedic groups, and by Vit D levels as sufficient, insufficient and deficient. 25(OH)Vit D sufficiency was ≥30 ng/mL, insufficiency <30 ng/mL and deficiency were <20 ng/mL. Patients were stratified and analysed. RESULTS: Between 2009 and 2018, there were 4426 patients who had 25(OH)Vit D testing. Vitamin D testing increased significantly (p<0.001) in the past 10 years. 43% of patients had sufficient 25(OH)Vit D levels, 41% had insufficient levels and 15% had deficient levels. CONCLUSION: More frequent testing has led to an increased identification of patients with insufficient and deficient 25(OH)Vit D levels. We found over 50% of patients tested were found to have 25(OH)Vit D levels under 30 ng/mL. There should be an increased awareness of patients with orthopaedic problems who may present with 25(OH) insufficiency.

Juvenile Hallux Valgus.

Treatment of juvenile hallux valgus can be challenging. Initial treatment with conservative measures is appropriate until exhausted. Surgical treatment should be delayed until after skeletal maturity when possible. Before any intervention, a thorough understanding of the whole patient and any underlying systemic contributors to their hallux valgus, in addition to the radiographic foot parameters, is imperative. Careful and individualized surgical planning should be done to optimize results and decrease the risk for recurrence.

Epiphysiodesis for Leg Length Discrepancy: A Cost Analysis of Drill Versus Screw Technique.

Research has demonstrated similar efficacy of drill epiphysiodesis and percutaneous epiphysiodesis using transphyseal screws for the management of adolescent leg length discrepancy. A cost analysis was performed to determine which procedure is more cost-effective. Patients seen for epiphysiodesis of the distal femur and/or proximal tibia and fibula between 2004 and 2017 were reviewed. A decision analysis model was used to compare costs. Two hundred thirty-five patients who underwent either drill (155/235, 66%) or screw (80/235, 34%) epiphysiodesis were analyzed with an average age at initial procedure of 13 years (range, 8.4 to 16.7 years). There was no significant difference in average initial procedure cost or total cost of all procedures across treatment groups (n = 184). The cost difference between drill and screw epiphysiodesis is minimal. In order for screw epiphysiodesis to be cost-favored, there would need to be a significant decrease in its cost or complication rate. (Journal of Surgical Orthopaedic Advances 30(3):181-184, 2021).

Prospective Evaluation of Tarsal Coalition Excision Show Significant Improvements in Pain and Function.

BACKGROUND: Excision of pediatric tarsal coalition has been successful in most patients. However, some patients have ongoing pain after coalition excision. This study prospectively assessed patient-based clinical outcomes before and after surgical excision of tarsal coalition, with particular emphasis on comparison to radiologic imaging. METHODS: We prospectively studied 55 patients who had symptomatic coalition excision for 2 years postoperatively. Patients filled out the modified American Orthopaedic Foot and Ankle Society score, the University of California Los Angeles activity score, and the simple question "does foot pain limit your activity" at 4 different time points: preoperative, 6 months postoperative, 12 months postoperative, and 24 months postoperative. Comparisons were done utilizing patient demographics, imaging parameters, and patient-reported outcomes. RESULTS: Compared with preoperative levels, patients showed improvements in all outcome parameters. Patients with calcaneonavicular coalitions showed initial rapid improvement with later slight decline, while patients with talocalcaneal coalitions showed more steady improvement; both were similar at 2 years postoperatively. CONCLUSIONS: This prospective study demonstrated remarkable clinical improvements after tarsal coalition excision regardless coalition type, though postoperative courses differed between calcaneonavicular and talocalcaneal types. Finally, a subset of patients has ongoing activity limiting foot pain after coalition excision which could not be explained by the data in this study. LEVEL OF EVIDENCE: Level II-prospective cohort study.

What Is New in Pediatric Bone Health.

BACKGROUND: This review paper aims to report on the last 5 years of relevant research on pediatric bone health in regard to nutrition and obesity, ethnic disparities, common orthopaedic conditions, trauma, spine, and sports medicine. METHODS: A search of the PubMed database was completed using the following terms: bone health, Vitamin D, pediatric, adolescent, sports medicine, fractures, spine, scoliosis, race, ethnicity, obesity, Slipped Capital Femoral Epiphysis, Osteogenesis Imperfecta, Duchenne's Muscular Dystrophy, neuromuscular, and cancer. Resultant papers were reviewed by study authors and determined to be of quality and relevance for description in this review. Papers from January 1, 2015 to August 31, 2020 were included. RESULTS: A total of 85 papers were selected for review. General results include 7 key findings. (1) Obesity inhibits pediatric bone health with leptin playing a major role in the process. (2) Socioeconomic and demographic disparities have shown to have a direct influence on bone health. (3) Vitamin D deficiency has been linked to an increased fracture risk and severity in children. (4) Formal vitamin D monitoring can aid with patient compliance with treatment. (5) Patients with chronic medical conditions are impacted by low vitamin D and need ongoing monitoring of their bone health to decrease their fracture risk. (6) Vitamin D deficiency in pediatrics has been correlated to low back pain, spondylolysis, and adolescent idiopathic scoliosis. Osteopenic patients with AIS have an increased risk of curve progression requiring surgery. Before spine fusion, preoperative screening for vitamin D deficiency may reduce complications of fractures, insufficient tissue repair, loosening hardware, and postoperative back pain. (7) Increasing youth sports participation has resulted in increased bone health related injuries. However, improved understanding of Relative Energy Deficiency in Sport effects on bone health has recently occurred. CONCLUSIONS: Increasing awareness of bone health issues in children will improve their recognition and treatment. Further research is needed on diagnosis, treatment, outcomes, and most importantly prevention of pediatric bone health diseases.

Institutional Variation in Surgical Rates and Costs for Pediatric Distal Radius Fractures: Analysis of the Pediatric Health Information System (PHIS) Database.

Background: Reduction of variations may streamline healthcare delivery, improve patient outcomes, and minimize cost. The purpose of this study was to characterize variations in surgical rates and hospital costs for treatment of pediatric distal radius fractures (DRFs) using Pediatric Health Information System (PHIS) database. Methods: The PHIS database was queried from 2009-2013 for DRFs in patients 4-18 years of age. Patients who underwent surgical treatment with internal fixation were identified using surgical CPT codes and/or ICD-9 procedure codes. 25 children's hospitals were included. Surgical rates and hospital costs were modeled. Rates were adjusted and standardized for gender, age, presence of other diagnoses, and year. Results: The aggregate rate of surgery for treatment of DRF was 2.65% and for open surgery was 0.81%. The standardized surgical rates for the 25 hospitals ranged widely, from 1.45% to 13.8% and for open surgical treatment from 0.51% to 4.27%. Six of the 25 hospitals had rates significantly higher than the aggregate for surgical treatment. Standardized hospital costs per patient ranged from $361 to $1,088 (2013 US dollars) across the hospitals with fairly uniform distribution. Conclusions: In the United States, there is great variability in practice and hospital costs of treatment of distal radius fractures. Further characterization of the root causes of these variations, and the effect, if any, on patient outcomes, is needed to improve value delivery in pediatric orthopaedic care.Level of Evidence: II.

Decreasing Resource Utilization Using Standardized Clinical Assessment and Management Plans (SCAMPs).

BACKGROUND: Standardized clinical assessment and management plans (SCAMPs) are a novel quality improvement initiative shown to improve patient care, diminish practice variation, and reduce resource utilization. Unlike clinical practice guidelines, a SCAMP is a flexible algorithm that undergoes iterative updates based on periodic data collection and review. We recently implemented a SCAMP for the closed treatment of pediatric torus fractures. The purpose of this study is to analyze the effect of SCAMP implementation on resource utilization, practice variability, cost of care, and outcomes. METHODS: This study was a retrospective review of prospectively collected data on 273 patients with pediatric torus fractures. The pre-SCAMP cohort included 116 subjects from 2008 to 2010. The SCAMP cohort included 157 subjects from 2011 to 2013. The pre-SCAMP cohort was treated according to the judgment of attending fellowship-trained pediatric orthopaedic surgeons. The SCAMP cohort was treated with a standardized algorithm including radiographs and splint application at initial presentation, with a single follow-up at 3 weeks. Patient demographics were analyzed to verify comparability between cohorts. Follow-up data including clinic visits, x-rays and practice variability was recorded. Costing analysis was conducted using time-derived activity-based costing methodology. Outcomes were compared using Poisson regression analysis. Incident rate ratios (IRR) with 95% confidence limits were estimated. RESULTS: No differences in clinical results were observed between the pre-SCAMP and SCAMP cohorts, and all patients demonstrated return to baseline activity at final follow-up. Patient demographics were comparable across cohorts. The SCAMP cohort had a 48% reduction in clinic visits [IRR, 0.52; 95% confidence interval (CI), 0.44-0.60; P<0.001], 60% reduction in x-rays (IRR, 0.40; CI, 0.33-0.47; P<0.001), and a 23% reduction in x-rays per clinic visit (IRR, 0.77; 95% CI, 0.65-0.91; P<0.001). Furthermore, SCAMP implementation resulted in a 49% reduction in the overall cost of care. CONCLUSIONS: SCAMPs provide a novel alternative to CPGs to implement cost effective changes in Orthopaedic practice. For pediatric torus fractures, SCAMP implementation resulted in decreased practice variability, resource utilization, and overall cost of care while maintaining clinical outcomes.

Patient- and Nurse-Controlled Analgesia: 22-Year Experience in a Pediatric Hospital.

OBJECTIVES: Pediatric pain management has rapidly changed over the last 2 decades. In this study, we describe the changing practices and adverse events (AEs) related to patient-controlled analgesia (PCA) and/or nurse-controlled analgesia (NCA) over a 22-year period. METHODS: After institutional review board approval, retrospective data from a single tertiary-care pediatric hospital were collected between 1994 and 2016. Subgroup analyses were done for surgical and medical case patients. We reported the number of times that PCA and/or NCA was ordered annually, the median and interquartile ranges for age, PCA and/or NCA duration and length of stay, and AE frequencies. RESULTS: Over 22 years, 32 338 PCAs and/or NCAs were ordered in this institution. Morphine and hydromorphone were used most commonly. Between 1994 and 2006, initial orders for PCA and/or NCA increased 2.5-fold. After 2007, initial orders for PCA and/or NCA rapidly decreased; after 2013, the decrease continued at a slower rate, with a total of 1007 orders in 2016. This decrease occurred despite increased hospital admissions and surgeries. Between 2007 and 2012, peripheral nerve blocks rapidly increased (10-fold). After 2002, 146 AEs were reported (1.0%). Of those, 50.5% were nonintercepted, and 20.6% were intercepted AEs; 5.5% and 6.2% were preventable and nonpreventable AEs, respectively. CONCLUSIONS: PCA and/or NCA usage continues to be common in pediatric patients, although usage has declined and stabilized in the setting of other emerging methods of analgesia and increases in the number of minimally invasive surgical procedures. The overall rate of AEs was extremely low. However, improvements to eliminate all errors are needed, especially with medications with a great risk of harm (such as opioids).

Radiographic Evaluation of First Metatarsal and Medial Cuneiform Morphology in Juvenile Hallux Valgus.

BACKGROUND: Operative treatment of juvenile hallux valgus (JHV) has a high recurrence rate. The aim of this study was to better understand the pattern of radiographic deformity. METHODS: Standing radiographs of 93 feet in 57 patients with JHV, and 50 feet in 36 normal patients were measured. Measurements included: hallux valgus angle (HVA), first metatarsal physis status (open or closed), intermetatarsal angle (IMA), distal metatarsal articular angle (DMAA), Meary's angle, medial cuneiform angle (MCA), relative first to second metatarsal length ratio (1:2 MT ratio), cuneiform obliquity (CO), and congruency of the metatarsophalangeal joint (MTPJ). JHV groups were defined as normal (HVA 0-15 degrees), mild-moderate (HVA 15-35), or severe (HVA > 35) and were analyzed. RESULTS: Seventy of 93 feet (75%) with JHV presented with mild-moderate JHV (average HVA of 26.2 ± 5.6 degrees), and 23 feet (25%, 23/93) presented with severe JHV (average HVA of 41.9 ± 5.3 degrees). Multivariable analysis determined that DMAA ( P < .001), MCA ( P = .04), and congruency ( P < .001) were independently associated with JHV and its severity (normal vs mild-moderate vs severe). Severe JHV cases had larger DMAA ( P = .01), larger IMA ( P = .01), larger 1:2 MT ratio ( P = .02), and were less frequently congruent ( P = .03) compared with mild-moderate JHV cases. CONCLUSION: Deformity in JHV was highly correlated with both the proximal and distal morphology of the first metatarsal and medial cuneiform. Severe JHV was associated with increased bony deformity and increased incongruity of the MTPJ. Treatment should be individualized, but JHV treatment algorithms can take this information into account. LEVEL OF EVIDENCE: Level III, comparative study.

Closed Versus Open Supracondylar Fractures of the Humerus in Children: A Comparison of Clinical and Radiographic Presentation and Results.

BACKGROUND: The purpose of this investigation was to compare the presentation and postoperative results of children treated for open and closed, completely displaced type III supracondylar humerus fractures (SCFs). METHODS: Thirty patients with open and 66 patients with closed, completely displaced type III SCFs were evaluated. Open fractures underwent irrigation and debridement, and all patients were treated by open or closed reduction and pin fixation. Medical records were reviewed to obtain demographic information as well as preoperative and postoperative clinical data regarding mechanism of injury, neurovascular status, associated injuries, postoperative range of motion, infections, and pain. Radiographs were evaluated to quantify displacement, Baumann's angle, humeral capitellar angle, position of the anterior humeral line, and adequacy of reduction. Outcomes were assessed using Flynn criteria. Mean clinical follow-up for the open and closed fracture groups was 8.9 and 5.7 months, respectively. RESULTS: Both groups were similar with respect to age, sex distribution, weight and body mass index, laterality of involvement, and mechanism of injury. At presentation, 35% of closed SCFs and 23% of open SCFs presented with abnormal neurovascular status. There was a higher prevalence of diminished/absent pulses or distal limb ischemia in patients with open injuries (27%) compared with closed fractures (18%). Conversely, severely displaced closed fractures were more commonly associated with nerve injury/palsy at presentation (35%) than those with open fractures (23%). Spontaneous nerve recovery was seen in 87% within 3 to 6 months. Postoperative loss of reduction and malunion were more common in the closed fracture group. However, 84% of patients achieved good-to-excellent results by Flynn criteria, with no appreciable difference based upon open versus closed fractures. CONCLUSIONS: With timely wound and fracture treatment, the clinical and radiographic results of children treated for open SCFs is similar to those with closed type III injuries, with little increased risk for infection, malunion, or neurovascular compromise. LEVEL OF EVIDENCE: Level III.

Noise Reduction to Reduce Patient Anxiety During Cast Removal: Can We Decrease Patient Anxiety With Cast Removal by Wearing Noise Reduction Headphones During Cast Saw Use?

BACKGROUND: Noise reduction headphones decrease the sound during cast removal. Their effectiveness in decreasing anxiety has not been studied. PURPOSE: Compare pediatric patients' anxiety levels during cast removal with and without utilization of noise reduction headphones combined with use of a personal electronic device. METHODS: Quality improvement project. Patients randomly assigned to noise reduction headphone group or standard care group during cast removal. Faces, Legs, Activity, Cry, and Consolability Scale and heart rate were evaluated prior to, during, and after cast removal. Data were compared across groups. RESULTS: Fifty patients were included; 25 per group. No difference detected between the 2 groups in Faces, Legs, Activity, Cry, and Consolability Scale score prior to (p = .05) or after cast removal (p = .30). During cast removal, the headphone group had lower FLACC Scale scores (p = .03). Baseline heart rate was lower in the headphone group prior to (p = .02) and after (p = .005) cast removal with no difference during cast removal (p = .24). CONCLUSION: Utilizing noise reduction headphones and a personal electronic device during the cast removal process decreases patient anxiety.

Subtalar Coalitions: Does the Morphology of the Subtalar Joint Involvement Influence Outcomes After Coalition Excision?

Posteromedial subtalar (PMST) coalitions are a recently described anatomic subtype of tarsal coalitions. We compared with clinical patient-based outcomes of patients with PMST and standard middle facet (MF) coalitions who had undergone surgical excision of their coalition. The included patients had undergone surgical excision of a subtalar tarsal coalition, preoperative computed tomography (CT), and patient-based outcomes measures after surgery (including the American Orthopaedic Foot and Ankle Society [AOFAS] scale and University of California, Los Angeles [UCLA], activity score). Blinded analysis of the preoperative CT scan findings determined the presence of a standard MF versus a PMST coalition. The perioperative factors and postoperative outcomes between the MF and PMST coalitions were compared. A total of 51 feet (36 patients) were included. The mean follow-up duration was 2.6 years after surgery. Of the 51 feet, 15 (29.4%) had a PMST coalition and 36 (70.6%) had an MF coalition. No difference was found in the UCLA activity score; however, the mean AOFAS scale score was higher for patients with PMST (95.7) than for those with MF (86.5; p = .018). Of the patients with a PMST, none had foot pain limiting their activities at the final clinical follow-up visit. However, in the group with an MF subtalar coalition, 10 (27.8%) had ongoing foot pain limiting activity at the final follow-up visit (p = .024). Compared with MF subtalar tarsal coalitions, patients with PMST coalitions showed significantly improved clinical outcomes after excision. Preoperative identification of the facet morphology can improve patient counseling and expectations after surgery.

Lisfranc injuries in children and adolescents.

In this descriptive analysis of pediatric Lisfranc injuries, records of 56 children treated for bony or ligamentous Lisfranc injuries over a 12-year period were reviewed. Overall, 51% of fractures and 82% of sprains were sports-related (P=0.03). A total of 34% of the cohort underwent open reduction internal fixation, which was more common among patients with closed physes (67%). Full weight bearing was allowed in open reduction internal fixation patients at a mean of 14.5 weeks, compared to 6.5 weeks in the nonoperative group. Complications were rare (4%) and included physeal arrest in one patient and a broken, retained implant in one patient.

Reducing the Incidence of Cast-related Skin Complications in Children Treated With Cast Immobilization.

BACKGROUND: Cast immobilization remains the mainstay of pediatric orthopaedic care, yet little is known about the incidence of cast-related skin complications in children treated with cast immobilization. The purposes of this quality improvement project were to: (1) establish a baseline rate of cast-related skin complications in children treated with cast immobilization, (2) identify trends in children who experienced cast-related skin complications, (3) design an intervention aimed at decreasing the rate of cast-related skin complications, and (4) determine the effectiveness of the intervention. METHODS: A prospective interrupted time-series design was used to determine the incidence of cast-related skin complications overtime and compare the rates of skin complications before and after an intervention designed to decrease the incidence of cast-related heel complications. All consecutive patients who were treated with cast immobilization from September 2012 to September 2014 were included. A cast-related skin complications data collection tool was used to capture all cast-related skin complications. A high rate of heel events was noted in our preliminary analysis and an intervention was designed to decrease the rate of cast-related skin complications, including the addition of padding during casting and respective provider education. RESULTS: The estimated cast-related skin events rate for all patients was 8.9 per 1000 casts applied. The rate for the total preintervention sample was 13.6 per 1000 casts which decreased to 6.6 in the postintervention sample. When examining the heel-only group, the rate was 17.1 per 1000 lower extremity casts applied in the preintervention group and 6.8 in the postintervention group. CONCLUSIONS: Incorporating padding to the heel of lower extremity cast was an effective intervention in decreasing the incidence of cast-related skin complications in patients treated with cast immobilization. LEVEL OF EVIDENCE: Level II.

Does Weather Matter? The Effect of Weather Patterns and Temporal Factors on Pediatric Orthopedic Trauma Volume.

OBJECTIVES: Orthopaedists often speculate how weather and school schedule may influence pediatric orthopedic trauma volume, but few studies have examined this. This study aims to determine: how do weather patterns, day, month, season and public school schedule influence the daily frequency of pediatric orthopedic trauma consults and admissions? METHODS: With IRB approval, orthopedic trauma data from a level 1 pediatric trauma center, including number of daily orthopedic trauma consults and admissions, were collected from July 2009 to March 2012. Historical weather data (high temperatures, precipitation and hours of daylight), along with local public school schedule data were collected for the same time period. Univariate and multivariate regression models were used to show the average number of orthopedic trauma consults and admissions as a function of weather and temporal variables. RESULTS: High temperature, precipitation, month and day of the week significantly affected the number of daily consults and admissions. The number of consults and admissions increased by 1% for each degree increase in temperature (p=0.001 and p<0.001, respectively), and decreased by 21% for each inch of precipitation (p<0.001, p=0.006). Daily consults on snowy days decreased by an additional 16% compared to days with no precipitation. November had the lowest daily consult and admission rate, while September had the highest. Daily consult rate was lowest on Wednesdays and highest on Saturdays. Holiday schedule was not independently significant. CONCLUSION: Pediatric orthopedic trauma consultations and admissions are highly linked to temperature and precipitation, as well as day of the week and time of year.

Posteromedial subtalar coalitions: prevalence and associated morphological alterations of the sustentaculum tali.

BACKGROUND: A variant form of subtalar coalition isolated to the posterior sustentaculum has been previously described, though its prevalence is not known and its relationship to the middle facet has not been characterized. OBJECTIVE: To determine the prevalence and morphological alterations of isolated posteromedial subtalar coalitions. MATERIALS AND METHODS: Computed tomography (CT) images of the foot or ankle performed from 2004 to 2012 were reviewed and 97 patients (mean age: 13.3+/-2.9 years; range: 9-19 years) with subtalar coalition were identified. In 41 (42%) of these, the condition was bilateral, yielding a total of 138 subtalar coalitions. In the 33 patients where CT demonstrated isolated posteromedial subtalar coalitions, multiplanar reformats along the long axis of the sustentaculum tali were generated, from which the anteroposterior dimensions of the sustentaculum tali and middle facet were measured. Posterior sustentaculum measurements defining the posterior extension of the sustentaculum beyond the middle facet were directly measured by two radiologists. Ratios of middle facet to posterior sustentaculum measurements were calculated. Thirty-three patients undergoing CT for ankle fracture served as controls. RESULTS: Ninety-seven of 138 coalitions (70.2%) affected the middle facet and 2/138 (1.4%) involved the posterior facet. There were 39 (28.2%) posteromedial subtalar coalitions in 33 patients. Mean AP measurements of the middle facet and posterior sustentaculum in patients with posteromedial subtalar coalitions were 12.6 mm and 18.2 mm, respectively, compared to 16.6 mm and 9.2 mm in controls (P<0.001). Mean middle facet/posterior sustenaculum (MF/PS) ratios were 0.74 for posteromedial subtalar coalitions vs. 1.92 for controls (P<0.001). CONCLUSION: Posteromedial subtalar coalitions comprise more than one-quarter of subtalar coalitions, and are associated with an intact, but shorter, middle facet and longer sustentaculum tali. This observation may aid in accurate diagnosis and management of this relatively common disorder.
