Objectives: To explore healthcare practitioners' views on management practices of self-harm in older adults., Methods: Semi-structured interviews were conducted with healthcare practitioners, including consultant psychiatrists, general practitioners, clinical psychologists, psychotherapists, clinical nurse specialists and social workers. Purposeful sampling was used to recruit participants in the Republic of Ireland ensuring diverse perspectives of healthcare practitioners were included. Healthcare practitioners were recruited advertising via professional and clinical research networks, social media, and snowballing methods. Interviews were audio-recorded, transcribed verbatim, and analysed using reflexive thematic analysis., Results: We conducted interviews with 20 healthcare practitioners from April to July 2023. Three main themes were generated: first, a perceived greater risk of suicide, and increased awareness of complexity in older adults' self-harm presentations. Second, integrated care as an avenue for improving the management of self-harm in older adults. Third, the importance of safety planning in risk assessments of older adults., Conclusions: Healthcare practitioners viewed self-harm in older adults as complex, challenging, and associated with high suicide risk, approaching patients with care and caution. The need for integrated support and improved collaboration between relevant healthcare practitioners was identified. Suggestions were made for primary care having a lead role in identifying and managing older adults after self-harm. Increased mental health promotion and awareness of mental health and self-harm in this age group would help address current stigma and shame., (© 2024 The Author(s).

Background: The toddler's fracture is a common pediatric nondisplaced spiral tibia fracture that is considered stable with a course of immobilization. However, there is no widely accepted type of immobilization, expected time to weight-bear, nor guidelines for radiographic monitoring. We aimed to compare immobilization type with respect to displacement and time to weight-bear, as well as determine the usefulness of follow-up radiographs., Methods: A 3-year retrospective chart review of all children aged 9 months to 4 years who had a lower leg radiograph was performed. Those who fulfilled the criteria of a nondisplaced spiral tibia fracture, without fibula or physeal injury, were included in data collection, as were subjects with a negative initial radiograph that were treated presumptively as a toddler's fracture. Subjects were compared with regard to clinical and radiographic presentation; initial and subsequent immobilization; and clinical and radiographic follow-up., Results: There were 606 subjects with lower leg radiographs, with 192 meeting study criteria: 117 (61%) with an initially visible fracture and 75 (39%) without. Of the 75 without initially visible fractures, 70 (93%) had robust periosteal reaction on follow-up, and none were diagnosed as anything further. At final follow-up, 184 (96%) were known to be weight-bearing, with 98% of these by 4 weeks. There was an earlier return to weight-bear for those initially treated in a boot compared with short leg cast (2.5 vs. 2.8 wk, P=0.04), but there were no other differences between immobilization type. No fractures displaced at any time point, including 7 that had received no immobilization. Patients received an average of 2.5 two-radiograph series; no radiographs were noted to affect treatment decisions in follow-up., Conclusions: In our cohort, initial immobilization of a toddler's fracture in a boot may allow faster return to weight-bearing, but fractures were universally stable regardless of immobilization type, and nearly all regained weight-bearing by 4 weeks. This reliable healing suggests that immobilization type can be at the physician and family's discretion, and that radiographic follow-up may be unnecessary for treatment planning., Level of Evidence: Level III-this is a retrospective comparative study.

Objective: There are currently no algorithms for early stratification of pediatric musculoskeletal infection (MSKI) severity that are applicable to all types of tissue involvement. In this study, the authors sought to develop a clinical prediction algorithm that accurately stratifies infection severity based on clinical and laboratory data at presentation to the emergency department., Methods: An IRB-approved retrospective review was conducted to identify patients aged 0 to 18 who presented to the pediatric emergency department at a tertiary care children's hospital with concern for acute MSKI over a 5-year period (2008 to 2013). Qualifying records were reviewed to obtain clinical and laboratory data and to classify in-hospital outcomes using a 3-tiered severity stratification system. Ordinal regression was used to estimate risk for each outcome. Candidate predictors included age, temperature, respiratory rate, heart rate, C-reactive protein (CRP), and peripheral white blood cell count. We fit fully specified (all predictors) and reduced models (retaining predictors with a P-value ≤0.2). Discriminatory power of the models was assessed using the concordance (c)-index., Results: Of the 273 identified children, 191 (70%) met inclusion criteria. Median age was 5.8 years. Outcomes included 47 (25%) children with inflammation only, 41 (21%) with local infection, and 103 (54%) with disseminated infection. Both the full and reduced models accurately demonstrated excellent performance (full model c-index 0.83; 95% confidence interval, 0.79-0.88; reduced model 0.83; 95% confidence interval, 0.78-0.87). Model fit was also similar, indicating preference for the reduced model. Variables in this model included CRP, pulse, temperature, and an interaction term for pulse and temperature. The odds of a more severe outcome increased by 30% for every 10 U increase in CRP., Conclusions: Clinical and laboratory data obtained in the emergency department may be used to accurately differentiate pediatric MSKI severity. The predictive algorithm in this study stratifies pediatric MSKI severity at presentation irrespective of tissue involvement and anatomic diagnosis. Prospective studies are needed to validate model performance and clinical utility., Level of Evidence: Level II-prognostic study.

Background: The rate of venous thromboembolism in children with musculoskeletal infections (MSKIs) is markedly elevated compared with hospitalized children in general. Predictive biomarkers to identify high-risk patients are needed to prevent the significant morbidity and rare mortality associated with thrombotic complications. We hypothesize that overactivation of the acute phase response is associated with the development of pathologic thrombi and we aim to determine whether elevations in C-reactive protein (CRP) are associated with increased rates of thrombosis in pediatric patients with MSKI., Methods: A retrospective cohort study measuring CRP in pediatric MSKI patients with or without thrombotic complications., Results: The magnitude and duration of elevation in CRP values correlated with the severity of infection and the development of pathologic thrombosis. In multivariable logistic regression, every 20 mg/L increase in peak CRP was associated with a 29% increased risk of thrombosis (P<0.001). Peak and total CRP were strong predictors of thrombosis with area under the receiver-operator curves of 0.90 and 0.92, respectively., Conclusions: Future prospective studies are warranted to further define the discriminatory power of CRP in predicting infection-provoked thrombosis. Pharmacologic prophylaxis and increased surveillance should be strongly considered in patients with MSKI, particularly those with disseminated disease and marked elevation of CRP., Level of Evidence: Level III.

Background: The purpose of this study was to determine if routine use of an intraoperative internal rotation stress test (IRST) for type 3 supracondylar humerus fractures will safely improve maintenance of reduction., Methods: An intraoperative protocol for type 3 supracondylar humerus fractures was adopted at our institution, consisting of fracture reduction, placement of 2 laterally based divergent pins, and then an IRST to determine the need for additional fixation with a medial column pin placed through a small open approach. Fractures treated with the prospective IRST protocol were compared with a retrospective cohort before adoption of the protocol (pre-IRST). The primary outcomes were differences in Baumann's angle, lateral humerocapitellar angle, and the rotation index between final intraoperative fluoroscopic images and radiographs at final follow-up. Secondary outcomes were complications such as iatrogenic nerve injury, loss of fixation, or need for reoperation., Results: There were 78 fractures in the retrospective cohort (pre-IRST) and 49 in the prospective cohort (IRST). Overall rotational loss of reduction (>6%), measured by lateral rotation percentage, and major rotational loss of reduction (>12%) were less common in the IRST cohort (6/49 vs. 27/78, P=0.007 overall; 0/49 vs. 8/78, P=0.02 major loss). There were no major losses of reduction for Baumann's angle (>12 degrees) in either cohort. There were 5 subjects in the pre-IRST cohort (6.4%) with a major loss of reduction of the humerocapitellar angle (>12 degrees) and none in the IRST cohort (P=0.16) Loss of proximal fixation with need for reoperation occurred in 3 fractures in the pre-IRST cohort, and none in the IRST cohort (P=0.28). There were no postoperative nerve injuries in either group., Conclusions: Intraoperative IRST after placement of 2 lateral pins assists with the decision for additional fixation in type 3 supracondylar humerus fractures. This method improved the final radiographic rotational alignment, and was safely performed using a mini-open approach for medial pin placement., Level of Evidence: Level III-prospective cohort compared with a retrospective cohort.

Background: Children undergoing posterior spinal fusion experience high blood loss often necessitating transfusion. An appropriately activated coagulation system provides hemostasis during surgery, but pathologic dysregulation can cause progressive bleeding and increased transfusions. Despite receiving antifibrinolytics for clot stabilization, many patients still require transfusions., Aims: We sought to examine the association of dilutional coagulopathy with blood loss and blood transfusion in posterior spinal fusion for pediatric scoliosis patients., Methods: A retrospective, single institution study of children undergoing posterior spinal fusion >6 levels with a standardized, prospective anesthetic protocol utilizing antifibrinolytics. Blood loss was evaluated using a hematocrit-based calculation. To evaluate transfusions, a normalized Blood Product Transfusion calculation was developed. Factors associated with blood loss and blood transfusions were determined by univariate analysis and multivariate regression modeling with multicollinearity and mediation analysis., Results: Patients received 73.7 mL/kg (standard deviation ±30.8) of fluid poor in coagulation factors. Estimated blood loss was 42.6 mL/kg (standard deviation ±18.0). There was a significant association between estimated blood loss and total fluids delivered (Spearman's rho = 0.51, 95% confidence interval 0.33-0.65, P < 0.001). Factors significantly associated with normalized Blood Product Transfusion in this cohort included age, weight, scoliosis type, levels fused, total osteotomies, pelvic fixation, total fluid, maximum prothrombin time, and minimum fibrinogen. Regression modeling showed the best combination of variables for modeling normalized Blood Product Transfusion included patient weight, number of levels fused, total fluid administered, and maximum prothrombin time., Conclusion: Blood product transfusion remains a frustrating problem in pediatric scoliosis. Identifying and controlling dilutional coagulopathy in these patients may reduce blood loss and the need for blood transfusion., (© 2018 John Wiley & Sons Ltd.)

Background: Factors that impact radiation exposure during operative fixation of pediatric supracondylar humerus (SCH) fractures have been investigated; however, no studies have measured the equivalent dose at the patient's radiosensitive organs. Our hypothesis was that intraoperative fluoroscopy exposes pediatric patients to a significant radiation load and lead shielding of radiosensitive organs is important. The goal of the study was to quantify the patient's radiation exposure during the procedure by measuring the radiation load at the thyroid and gonads., Methods: A prospective quality improvement project of radiation exposure during percutaneous fixation of isolated SCH fractures was performed over a 4-week period. The c-arm image intensifier was used as the operating table and radiation dosimeters were positioned over the thyroid and gonadal lead shields. Fluoroscopy times were recorded, doses were calculated, and the dosimeters were analyzed. To assure that the prospective cohort was representative of a larger population of SCH fractures, demographics and fluoroscopy time of the prospective cohort were compared with a 12-month retrospective cohort in which dosimetry was not performed., Results: Prospective cohort-18 patients with type 2 (8) and type 3 (10) fractures were prospectively studied with intraoperative measurement of thyroid and gonadal radiation equivalent doses. Mean age was 4.9 years (1.9 to 9.5 y) and mean weight was 21.4 kg (13.1 to 33.5 kg). Mean fluoroscopy time was 65.0 seconds (25.3 to 168.4 s), and absorbed skin dose at the elbow was 0.47 mGy (0.18 to 1.21 mGy). The radiation dosimeters overlying the thyroid and gonads measured minimal radiation indicating equivalent doses of <0.01 mSv for all patients in the prospective cohort.Retrospective cohort-163 patients with type 2 (60) and type 3 (103) fractures were retrospectively studied. The mean age was 5.5 years (0.02 to 13.7 y) and weight was 21.6 kg (2.0 to 71.9 kg). Mean fluoroscopy time was 74.1 seconds (10.2 to 288.9 s), and absorbed skin dose at the elbow was 0.53 mGy (0.07 to 2.07 mGy).There were no statistically significant differences between the cohorts., Conclusions: The smaller prospective cohort had fluoroscopy times and radiation doses that were not statistically different from the larger retrospective cohort, suggesting that the dosimeter measurements are representative of intraoperative radiation exposure during fixation of pediatric SCH fractures. The equivalent dose to the thyroid and gonads was minimal and approximates daily background radiation. Shielding of radiosensitive organs is appropriate when practical to minimize cumulative lifetime radiation exposure, particularly in smaller patients and when longer fluoroscopy times are anticipated., Level of Evidence: Level 2.

Background: Musculoskeletal infections (MSKIs) are a common cause of pediatric hospitalization. Children affected by MSKI have highly variable hospital courses, which seem to depend on infection severity. Early stratification of infection severity would therefore help to maximize resource utilization and improve patient care. Currently, MSKIs are classified according to primary diagnoses such as osteomyelitis, pyomyositis, etc. These diagnoses, however, do not often occur in isolation and may differ widely in severity. On the basis of this, the authors propose a severity classification system that differentiates patients based on total infection burden and degree of dissemination., Methods: The authors developed a classification system with operational definitions for MSKI severity based on the degree of dissemination. The operational definitions were applied retrospectively to a cohort of 202 pediatric patients with MSKI from a tertiary care children's hospital over a 5-year period (2008 to 2013). Hospital outcomes data [length of stay (LOS), number of surgeries, positive blood cultures, duration of antibiotics, intensive care unit LOS, number of days with fever, and number of imaging studies] were collected from the electronic medical record and compared between groups., Results: Patients with greater infection dissemination were more likely to have worse hospital outcomes for LOS, number of surgeries performed, number of positive blood cultures, duration of antibiotics, intensive care unit LOS, number of days with fever, and number of imaging studies performed. Peak C-reactive protein, erythrocyte sedimentation rate, white blood cell count, and temperature were also higher in patients with more disseminated infection., Conclusions: The severity classification system for pediatric MSKI defined in this study correlates with hospital outcomes and markers of inflammatory response. The advantage of this classification system is that it is applicable to different types of MSKI and represents a potentially complementary system to the previous practice of differentiating MSKI based on primary diagnosis. Early identification of disease severity in children with MSKI has the potential to enhance hospital outcomes through more efficient resource utilization and improved patient care., Level of Evidence: Level II-prognostic study.

Tibial fractures in children present a wide array of challenges to the managing orthopaedic surgeon. Injuries cover a spectrum from subtle tibial spine fractures to comminuted high-energy shaft fractures requiring free flap coverage. Significant risks range from malunion and leg length discrepancy to infected nonunions and Volkmann ischemic contracture. This article offers evidence and experience-based advice that is aimed at helping the community orthopaedic surgeon taking call.

Background: Slipped capital femoral epiphysis (SCFE) is strongly associated with childhood obesity, yet the prevalence of obesity is orders of magnitude greater than the prevalence of SCFE. Therefore, it is hypothesized that obesity is not, by itself, a sufficient condition for SCFE, but rather one component of a multifactorial process requiring preexisting physeal pathology. Leptin elevation is seen to varying degrees in patients with obesity, and as leptin has been shown to cause physeal pathology similar to the changes seen in SCFE, we propose that leptin may be a factor distinguishing between patients with SCFE and equally obese children without hip abnormalities., Methods: Serum leptin levels were obtained from 40 patients with SCFE and 30 control patients with approximate body mass index (BMI) matching. BMI percentiles were calculated according to Centers for Disease Control and Prevention population data by patient age and sex. Patients were compared by demographic characteristics, leptin levels, odds of leptin elevation, and odds of SCFE., Results: The odds of developing SCFE was increased by an odds ratio of 4.9 (95% confidence interval [CI], 1.31 to 18.48; p < 0.02) in patients with elevated leptin levels, regardless of obesity status, sex, and race. When grouping patients by their obesity status, non-obese patients with SCFE showed elevated median leptin levels at 5.8 ng/mL compared with non-obese controls at 1.7 ng/mL (p = 0.006). Similarly, obese patients with SCFE showed elevated median leptin levels at 17.9 ng/mL compared with equally obese controls at 10.5 ng/mL (p = 0.039). Serum leptin levels increased in association with obesity (p < 0.001), with an increase in leptin of 0.17 ng/mL (95% CI, 0.07 to 0.27 ng/mL) per BMI percentile point., Conclusions: To our knowledge, this study is the first to clinically demonstrate an association between elevated serum leptin levels and SCFE, regardless of BMI. This adds to existing literature suggesting that SCFE is a multifactorial process and that leptin levels may have profound physiological effects on the development of various disease states. Despite a strong association with adiposity, leptin levels vary between patients of equal BMI and may be a vital resource in prognostication of future obesity-related comorbidities., Level of Evidence: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Background: Slipped capital femoral epiphysis (SCFE) and tibia vara (Blount disease) are associated with childhood obesity. However, the majority of obese children do not develop SCFE or tibia vara. Therefore, it is hypothesized that other obesity-related biological changes to the physis, in addition to increased biomechanical stress, potentiate the occurrence of SCFE and tibia vara. Considering that hypertension can impose pathologic changes in the physis similar to those observed in these obesity-related diseases we set out to determine the prevalence of hypertension in patients with SCFE and tibia vara., Methods: Blood pressure measurements were obtained in 44 patients with tibia vara and 127 patients with SCFE. Body mass index and blood pressure were adjusted for age, sex, and height percentiles utilizing normative distribution data from the CDC. These cohorts were compared with age-matched and sex-matched cohorts derived from an obesity clinic who did not have either bone disease. A multivariable proportional odds model was used to determine association., Results: The prevalence of prehypertension/hypertension was significantly higher in the tibia vara (64%) and SCFE cohort (64%) compared with respective controls (43%). Patients diagnosed with either SCFE or tibia vara had 2.5-fold higher odds of having high blood pressure compared with age-matched and sex-matched obese patients without bone disease. Sex, age, and race did not have a significant effect on a patient's blood pressure., Conclusions: This is the first study to establish that the obesity-related bone diseases, SCFE and tibia vara, are significantly associated with high blood pressure. These data have immediate clinical impact as they demonstrate that children with obesity-related developmental bone disease have increased prevalence of undiagnosed and untreated hypertension. Furthermore, this prevalence study supports the hypothesis that hypertension in conjunction with increased biomechanical forces together potentiate the occurrence of SCFE and tibia vara. If proven true, it is plausible that hypertension may represent a modifiable risk factor for obesity-related bone disease., Level of Evidence: Level III-case-control study.

Accessory muscles are easily overlooked during imaging evaluation. Although usually discovered incidentally, they are occasionally symptomatic. With increasing utilization of cross-sectional imaging, the radiologist should be prepared to readily identify these anomalous muscles. It is particularly important to distinguish these anatomical variants from soft-tissue tumors prior to invasive intervention, reserving biopsy and surgery for children who are symptomatic. This report discusses a case of a flexor digitorum superficialis indicis muscle, an extremely rare but well-described accessory muscle, presenting as a painful mass in a 15-year-old girl. The report includes the clinical presentation, radiologic findings, and the significance to management.

Background: The purpose of this study was to compare hemiepiphysiodesis implants for late-onset tibia vara and to evaluate patient characteristics that may predict surgical failure., Methods: This is a retrospective review of late-onset tibia vara patients treated with temporary hemiepiphysiodesis from 1998 to 2012. Mechanical axis deviation (MAD), mechanical axis angle, mechanical lateral distal femoral angle, and medial proximal tibial angle were measured on standing bone length radiographs. Surgical failure was defined as residual deformity requiring osteotomy, revision surgery, or MAD exceeding 40 mm at the time of final follow-up. Implant failure was recorded. Costs included implants and disposables required for construct placement. Staple constructs included 2 or 3 staples. Plate constructs included the plate, screws, guide wires, and drill bits., Results: A total of 25 patients with 38 temporary lateral proximal tibia hemiepiphysiodeses met the inclusion criteria. The average body mass index (BMI) was 39.1 kg/m with an average follow-up of 3.0 years (minimum 1 y). Surgical failure occurred in 57.9% of patients. Greater BMI (P=0.05) and more severe deformity (MAD, mechanical axis angle, and medial proximal tibial angle; P<0.01) predicted higher rates of surgical failure. Younger age predicted higher rates of implant failure (P<0.01). There were no differences in surgical or implant failure between staple and plate systems. Hospital costs of plate constructs ($781 to $1244) were 1.5 to 3.5 times greater than the staple constructs ($332 to $498)., Conclusions: Greater BMI, more severe deformity, and younger age were predictive of surgical or implant failure. There was no difference in success between implant types, whereas the cost of plate constructs was 1.5 to 3.5 times greater than staples. The rate of surgical failure was high (58%) and consideration should be given to reserving hemiepiphysiodesis for patients with lower BMI and less severe deformity. In our population, if hemiepiphysiodesis was not offered to patients with BMI>35 or MAD>80 mm varus, the surgical failure rate would diminish to 28%. The failure rate outside these parameters would be 88%., Level of Evidence: Level II—Prognostic.

Introduction: We describe rigid intramedullary nailing using a trochanteric entry for internal fixation of femoral shaft fractures in older children and adolescents., Step 1 Preparation Prior to Incision: Appropriate preparation prior to the operation is key to minimizing intraoperative and postoperative complications., Step 2 Perform Incision and Exposure: A well-positioned incision will facilitate and reduce difficulty with ideal guidewire placement., Step 3 Place and Overream the Guide Pin: Ensure that the guide pin is properly positioned on the greater trochanter, while avoiding the piriformis fossa., Step 4 Place the Guidewire and Reduce the Fracture: Prepare the definitive guidewire. Insert the guidewire into the proximal fragment via the trochanteric portal. While maintaining the fracture reduction, advance the guidewire into the distal fragment., Step 5 Measure Nail Length and Begin Overreaming: Pay careful attention to the amount of reaming as well as distraction across the fracture site to provide the best fit for the nail., Step 6 Insert the Nail: Be sure to maintain the reduction while advancing the nail across the fracture site. Reconfirm that traction has been reduced to avoid distraction at the fracture site., Step 7 Insert Proximal and Distal Interlocks: Use the interlocking screws to secure the proper rotational alignment., Step 8 Make Final Images and Close the Wound: Confirm the reduction and adequate fixation before closure., Results: In our original study, a cohort of 246 femoral shaft fractures among 241 skeletally immature patients treated with trochanteric entry rigid intramedullary nailing was retrospectively reviewed.IndicationsContraindicationsPitfalls & Challenges.

Study Design: Retrospective cohort analysis., Objective: To establish if drain levels exceed the minimum inhibitory concentrations for common pathogens (methicillin-resistant Staphylococcus aureus, methicillin-sensitive Staphylococcus aureus, and Propionibacterium acnes-2 μg/mL; Staphylococcus epidermidis, Enterococcus faecalis-4 μg/mL). Evaluate the safety of topical vancomycin in pediatric patients undergoing spinal deformity surgery and determine if postoperative serum levels approach toxicity (25 μg/mL)., Summary of Background Data: The application of topical vancomycin powder has decreased postoperative wound infections in retrospective analyses in the adult population with minimal local and systemic risks. The safety and efficacy of vancomycin powder has not been completely evaluated in the pediatric population after deformity surgery., Methods: Topical vancomycin powder (1 g) was applied during wound closure after instrumented posterior spinal fusion. All patients received intravenous perioperative antibiotics and a subfascial drain was used. Serum and drain vancomycin levels were collected immediately postoperatively and during the first 2 postoperative days (PODs). Complications were recorded., Results: The study population consisted of 25 patients with a mean age of 13.5 years (9.5-17.1 yr) and mean ± standard deviation body weight of 44.5 ± 18 kg. Underlying diagnoses included: adolescent idiopathic scoliosis (12), neuromuscular scoliosis (10), and kyphosis (3). Mean serum vancomycin levels trended downward from 2.5 μg/mL (POD 0) to 1.9 μg/mL (POD 1) to 1.1 μg/mL (POD 2). Mean drain levels also trended downward from 403 μg/mL (POD 0) to 251 μg/mL (POD 1) to 115 μg/mL (POD 2). No vancomycin toxicity or deep wound infections were observed. One patient with neuromuscular scoliosis developed a superficial wound dehiscence that was managed with dressing changes., Conclusion: Topical application of vancomycin powder in pediatric spinal deformity surgery produced local levels well above the minimum inhibitory concentration for common pathogens and serum levels below the toxicity threshold (25 μg/mL). There were no deep wound or antibiotic related complications., Level of Evidence: 3.

Background: Debate exists over the safety of rigid intramedullary nailing of femoral shaft fractures in skeletally immature patients. The goal of this study was to describe functional outcomes and complication rates of rigid intramedullary nailing in pediatric patients., Methods: A retrospective review was performed of femoral shaft fractures in skeletally immature patients treated with trochanteric rigid intramedullary nailing from 1987 to 2009. Radiographs made at initial injury, immediately postoperatively, and at the latest follow-up were reviewed. Patients were administered the Nonarthritic Hip Score and a survey., Results: The study population of 241 patients with 246 fractures was primarily male (75%) with a mean age of 12.9 years (range, eight to seventeen years). The majority of fractures were closed (92%) and associated injuries were common (45%). The mean operative time was 119 minutes, and the mean estimated blood loss was 202 mL. The mean clinical follow-up time was 16.2 months (range, three to seventy-nine months), and there were ninety-three patients with a minimum two-year clinical and radiographic follow-up. An increase of articulotrochanteric distance of >5 mm was noted in 15.1% (fourteen of ninety-three patients) at a minimum two-year follow-up; however, clinically relevant growth disturbance was only observed in two patients (2.2%) with the development of asymptomatic coxa valga. There was no femoral head osteonecrosis. Among the 246 fractures, twenty-four complications (9.8%) occurred. At the time of the latest follow-up, 1.7% (four of 241 patients) reported pain. The average Nonarthritic Hip Score was 92.4 points (range, 51 to 100 points), and 100% of patients reported satisfaction with their treatment., Conclusions: Rigid intramedullary nailing is an effective technique for treatment of femoral shaft fractures in pediatric patients with an acceptable rate of complications., Level of Evidence: Therapeutic Level IV.

Background: In a recent study designed to determine the anatomic location of infection in children presenting with acute hip pain, fever, and elevated inflammatory markers, we demonstrated the incidence of infection of the musculature surrounding the hip to be greater than twice that of septic arthritis. Importantly, the obturator musculature was infected in >60% of cases. Situated deep in the pelvis, surrounding the obturator foramen, debridement of these muscles and placement of a drain traditionally requires an extensive ilioinguinal or Pfannenstiel approach, placing significant risk to the surrounding neurovascular structures. We hypothesized that the obturator internus and externus could be successfully debrided using a limited medial approach., Methods: An IRB-approved prospective study of children (0 to 18 y) evaluated in the pediatric emergency department by an orthopaedic surgeon to rule out septic hip arthritis at a tertiary care children's hospital (July 1, 2010 to June 30, 2012) was conducted. Infected obturator musculature was identified and confirmed using magnetic resonance imaging. Cadaveric dissection was performed comparing the ilioinguinal, Pfannenstiel, and proposed minimally invasive medial approach. The proposed approach was utilized to debride and place drains in 7 consecutive patients., Results: Anatomic information gained from magnetic resonance images of patients with abscess within the obturator musculature, and from the results of cadaveric studies, allowed for planning of a novel surgical approach. We found that through the surgical approach used to perform an osteotomy of the ischium (Tonnis) the obturator externus could be debrided through the adductor brevis and the obturator internus could be debrided through the obturator foramen. Using our medial approach, resolution of symptoms in all children who underwent surgical drainage resulted without complication., Conclusions: Our medial approach can safely access the obturator musculature for abscess decompression and drain placement with successful results. Advantages to this approach include: lower risk to neurovascular structures within the pelvis, less soft tissue trauma, and similarity to current techniques used for adductor lengthening, medial reduction of the dislocated hip, and osteotomy of the ischium., Level of Evidence: Level II.

Background: Flexible intramedullary nailing (IMN) has become a popular technique for the management of unstable or open forearm fractures. Recent publications have suggested an increased incidence of delayed union and poor outcomes in older children and adolescents. The objective of this study was to review forearm fractures treated with IMN, comparing the rate of complications and outcomes between the 2 age groups. Our hypothesis was that IMN is an effective technique with a similar rate of complications in both age groups., Methods: An Institutional Review Board-approved retrospective review was conducted of pediatric forearm fractures treated from 1998 to 2008 at a single institution. Over the study time period, 4161 pediatric forearm fractures were managed nonoperatively (92%) and 353 were treated operatively with plate, cross-pin, or intramedullary fixation (8%). Patients with inadequate follow-up, cross-pin, or plate fixation were excluded. Medical records were reviewed for indications and complications. Complications were graded with a modification of the Clavien-Dindo classification. Outcomes were judged by a new grading system., Results: A total of 205 forearm fractures treated with IMN in 203 patients were identified. The mean age was 9.7 years (range, 1.7 to 16.2 y) and mean follow-up was 42 weeks. Operative indications were failure of closed treatment in 165 (80%) and open fracture in 40 (20%). Mean time from injury to IMN was 5.9 days (range, 0 to 25 d). Single bone IMN was performed in 40 of 185 both bone fractures (26%); there were 20 single-bone forearm fractures treated with IMN. Open reduction was required in 61/165 (37%) of closed fractures. Asymptomatic delayed union (grade 1 complication) was observed in 9 fractures (4%). More severe complications were noted in 17% (grade 2 to 4 complications). Postoperative compartment syndrome occurred in 3 isolated forearm fractures with a significant younger mean age (6.0 vs. 10 y, P=0.031). Overall, complications were significantly more frequent in children older than 10 years of age (25/101) as compared with younger children (13/104, P=0.031). In particular, delayed union was more common in children over the age of 10 years (9/101 vs. 1/104, OR=9.99, P=0.009). Outcomes were good or excellent in 91% of fractures. There was no statistical association of patient age with a fair or poor outcome., Conclusions: IMN is an effective technique for pediatric forearm fractures with good to excellent outcomes in 91%. Complications are not infrequent with this technique, with complications of grade 2 to 4 severity in 17%. There was a 2-fold increase in the rate of complications in children over the age of 10 years. Compartment syndrome was more common in younger children. Patients and families should be counseled about the risks preoperatively.

Objectives: Group A streptococcus (GAS) is a frequent cause of pediatric musculoskeletal infections including septic arthritis, acute rheumatic fever (ARF), and a more benign arthritis called post-streptococcal reactive arthritis. Children with painful joints are frequently evaluated in the acute care setting, and because the presentation of each of these entities is similar, the diagnosis can be difficult to make. Five cases of children with GAS arthridities are presented to demonstrate the spectrum of GAS-associated joint pathologies encountered in the acute care setting and also to discuss how GAS laboratory tests may assist in the evaluation and management of children presenting with a painful joint., Methods: Five cases of GAS-associated joint pathology are presented. Evaluation of these patients was conducted using a diagnostic algorithm derived from a literature review of post-streptococcal reactive arthritis and ARF, as well as the current clinical practice guideline for the diagnosis and treatment of septic arthritis., Results: The 5 cases presented include 1 case of transient synovitis, 2 cases of inflammatory synovitis, 1 case of septic arthritis, and 1 case of ARF., Conclusions: Determining the cause of joint pain in the acute care setting is challenging. The addition of the GAS laboratory tests to a diagnostic algorithm based on clinical examination and monitoring systemic inflammation can help to identify patients with ARF and septic arthritis in the acute care setting. In addition, GAS-specific laboratory tests may help to identify cases of nonseptic, non-ARF GAS joint pathology.

Background: Epiphyseal cartilage enhancement defects (ED) may occur in the setting of epiphyseal osteomyelitis (OM), and its significance is uncertain., Objective: The aim of this study is to evaluate the incidence and clinical impact of epiphyseal cartilage ED in pediatric epiphyseal OM., Materials and Methods: The 13 children involved in this retrospective review were younger than 6 years of age and diagnosed with OM. They underwent contrast-enhanced MRI and surgical exploration yielding 14 study epiphyses. Seventeen age-matched children without evidence of infection who underwent contrast-enhanced MRI in the same period yielded 28 control epiphyses. Images were reviewed for focal/global ED, correlated with cartilage abscesses and compared with surgical reports., Results: Study and control ED were respectively present in 10/14 (71.4%-6 global, 4 focal) and 6/28 (21.4%-0 global, 6 focal), P=0.0017. An analysis of ED patterns between study and control patients showed significant difference for global (P=0.0006), but no difference for focal ED (P=0.71). For the six study epiphyses with global ED, epiphyseal abscesses were present in two (33.3%). For the four study epiphyses with focal ED, epiphyseal abscesses were present in two (50%). For the controls, no abnormalities were found on follow-up of epiphyses with focal ED., Conclusion: ED are seen normally but more commonly in children with OM. ED should not be confused with epiphyseal abscesses.

The purpose of this study is to determine the effect on hip rotation of hamstring lengthening as measured by preoperative and postoperative motion analysis. Thirty-eight patients/76 hips in children with cerebral palsy spastic diplegia were retrospectively reviewed using presurgical and postsurgical gait analysis. Physical examination and gait analysis showed an increase in knee extension and decreased popliteal angles postoperatively. Kinematic analysis showed an increase in knee extension and decreased hip internal rotation throughout the gait cycle postoperatively as well. No difference was seen between those with internal and external rotation pattern at the hip preoperatively. As a group, the patients did not improve enough to change from internal to external rotation at the hip, suggesting that children with cerebral palsy spastic diplegia with significant internal rotation gait should have other surgical options besides hamstring lengthening when internal rotation gait of the hip is to be treated.
