Background: The etiology of hip pain in pediatric and adolescent patients can be unclear. Osteoid osteoma (OO) about the hip in children has only been described in case reports or small studies. The present study assessed the clinical presentation and diagnostic course, imaging, and treatment approaches in a large cohort of pediatric cases of OO about the hip. Methods: Medical record and imaging results were reviewed for all cases of OO identified within or around the hip joint in patients 6 months occurred in 43% of patients. Three patients underwent operative procedures for other hip diagnoses, but all had persistent postoperative pain until the OO was treated. Of the 41 patients (82%) who ultimately underwent radiofrequency ablation (RFA), 38 (93%) achieved complete post-RFA symptom resolution. Conclusions: Initial misdiagnosis, the most common of which was FAI, and delayed correct diagnosis are common in pediatric OO about the hip. Presenting complaints were variable and nonspecific MRI findings were frequent. Night pain and relief with NSAIDs were present in the vast majority of cases. CT scans provided definitive diagnosis in all patients who received them. As increasing numbers of young, active patients are being evaluated for various causes of hip pain, such as FAI, OO should not be overlooked in the differential diagnosis.

Background: Displaced supracondylar humeral fractures (SCHFs) benefit from closed reduction and percutaneous pinning. In Malawi, many SCHFs are treated nonoperatively because of limited surgical capacity. We sought to assess clinical and functional outcomes of nonoperatively treated SCHFs in a resource-limited setting. Methods: We retrospectively reviewed all patients with SCHFs treated at Nkhotakota District Hospital (NKKDH) in Malawi between January 2014 and December 2016. Patients subsequently underwent clinical and functional follow-up assessment. Results: We identified 182 children (54% male, mean age of 7 years) with an SCHF; 151 (83%) of the fractures were due to a fall, and 178 (98%) were extension-type (Gartland class distribution: 63 [35%] type I, 52 [29%] type II, and 63 [35%] type III). Four patients with type-I fractures were treated with an arm sling alone, and 59 were treated with straight-arm traction to reduce swelling and then splint immobilization until union. All 119 of the patients with Gartland type-II and III or flexion-type injuries were treated with straight-arm traction, manipulation under anesthesia without fluoroscopy, and then splint immobilization until union. A total of 137 (75%) of the patients were available for follow-up, at a mean of 3.9 years after injury. The Flynn functional outcome was excellent for 39 (95%) with a type-I fracture, 30 (70%) with type-II, and 14 (29%) with type-III. The Flynn cosmetic outcome was excellent for 40 (98%) with a type-I fracture, 42 (98%) with type-II, and 41 (84%) with type-III. Forty (98%) of the children with a type-I fracture, 41 (95%) with type-II, and 32 (65%) with type-III returned to school without limitation. Controlling for sex, delayed presentation, medical comorbidities, injury mechanism, and skin blistering/superinfection during traction, patients with type-II fractures were 5.82-times more likely (95% confidence interval [CI], 1.71 to 19.85) and those with type-III fractures were 9.81-times more likely (95% CI, 3.00 to 32.04), to have a clinical complication or functional limitation compared with patients with type-I fractures. Conclusions: Nonoperative treatment of type-III SCHFs resulted in a high risk of clinical complications or functional impairment. These results illustrate the urgent need to increase surgical capacity in low-income countries like Malawi to improve pediatric fracture care. Level of Evidence: Therapeutic Level III.

Update: This article was updated on April 5, 2022, because of a previous error. On page 1, the article type listed above the title that had read “Key Procedures” now reads “Subspecialty Procedures.” Background: Fracture of the medial epicondyle is a common pediatric injury, with an estimated annual incidence of 40 to 60 per 100,000 people per year ^1–3 . Medial epicondylar fractures are associated with elbow dislocation in about 60% of cases, and ulnar nerve dysfunction is reported to occur nearly 10% of the time ^2,4 . No standard of care for medial epicondylar fracture exists, as similar outcomes have been demonstrated in observational studies with both operative and nonoperative treatment ^5,6 . Increasingly, however, these injuries are being treated with surgical intervention, which in most cases consists of a single screw affixing the osseous piece back to its donor site on the humerus ^7–9 . There is broad consensus on the absolute indications for operative treatment, including an open fracture and an incarcerated epicondylar fragment ^1,10–13 . The relative indications are more controversial and include ulnar nerve dysfunction, elbow instability, increased fragment displacement, and high-level throwing or upper-extremity weight-bearing athletes ^2,9,14–16 . Description: The patient is placed in the prone position with the operative arm on a radiolucent arm board. A milking maneuver with an Esmarch bandage is utilized. A posteromedial incision is made over the medial epicondyle. The ulnar nerve is protected posteriorly. The fracture is easily reduced under minimal tension, and then 1 or 2 guidewires from the 4.0-mm cannulated screw kit are placed to fix the fragment. The central guidewire is overreamed, and then a partially threaded 4.0-mm screw is placed in a relative posterior-to-anterior trajectory within the medial column of the elbow. Alternatives: Nonoperative treatment includes immobilization in a long arm cast until fragment healing. Complications associated with nonoperative treatment include nonunion and late instability. Supine positioning is a reasonable alternative to the prone position described here. In that case, the fracture is fixed with the arm in external rotation of the shoulder and with the elbow extended. Rationale: Prone positioning for operative treatment of medial epicondylar fractures is preferred because the tension from the flexor pronator mass associated with supine positioning is negated, facilitating an easier fracture reduction and improved anatomic reduction. Expected Outcomes: To our knowledge, there are currently no Level-I or Level-II prospective studies reporting on the outcomes of operative versus nonoperative treatment of medial epicondylar fractures. A systematic review of retrospective results suggested no difference in pain or clinical outcomes, but >9-times greater odds of union with operative treatment ^5,6 . Expectations following operative treatment of a medial epicondylar fracture have been explored in multiple studies. Generally, return to full levels of activity and near-normal range of motion of the elbow have been demonstrated by most. Minor rates of range-of-motion limitation, including extension deficit (4% with deficit up to 20°) are reported in some studies ⁸ . In the setting of preoperative instability, the expectation is that elbow stability will be achieved by operative treatment ^7,8 . Important Tips: Perform and document an accurate preoperative neurovascular examination of the arm. Test the shoulder in internal rotation prior to prone positioning. Protect the ulnar nerve during surgical fixation and drilling. Confirm that the screw trajectory is relatively posterior to anterior and only in the medial column of the elbow.

Background: Online patient information (OPI) plays an important role in pediatric orthopaedic patient/caregiver education and decision-making. We assessed the availability and readability of OPI about osteosarcoma found at pediatric hospital and U.S. National Cancer Institute-designated cancer center (NCIDCC) websites. Methods: The websites of all NCIDCCs and the top 50 pediatric hospitals identified using U.S. News & World Report were included. The names of NCIDCCs and pediatric hospitals along with the terms “osteosarcoma,” “bone sarcoma,” and “sarcoma” were entered into Google.com, and were classified according to the availability of osteosarcoma-specific web pages. Unpaid monthly visits were assessed using the Ahrefs.com Organic Traffic Score (OTS) metric. Readability was assessed using 5 validated metrics and the composite grade level (CGL), the rounded mean of the 5 metrics. Results: Of the 71 NCIDCCs and 50 pediatric hospitals, 48 (67.6%) and 18 (36.0%), respectively, did not have at least 1 web page dedicated to osteosarcoma-specific OPI. The mean OTS for all 116 NCIDCC and pediatric hospital osteosarcoma-specific web pages assessed was 177 estimated visits per month, which was less than the mean OTS for the top 10 Google.com “osteosarcoma” search results (3,287.9; p < 0.001). The 52 NCIDCC web pages with osteosarcoma OPI (representing 23 centers) had an average CGL of 12.9, representing a readability level of at least a high school degree. The mean CGL for the 64 pediatric hospital web pages with osteosarcoma OPI (representing 32 hospitals) was 12.8, also representing readability of at least a high school degree. Only 8 (12.5%) of the 64 web pages were written at a seventh or eighth-grade level. Conclusions: Taken together, the majority of NCIDCCs and pediatric hospitals did not have a dedicated page of OPI for osteosarcoma. Of those that did, NCIDCC and pediatric hospital sites were visited much less frequently than sites visited through the most common Google.com searches. None of the osteosarcoma web pages offering OPI from NCIDCCs and pediatric hospitals met the American Medical Association readability recommendation (sixth-grade reading level). Therefore, greater effort must be made to create and direct patients and parents toward high-quality OPI of the appropriate level. Clinical Relevance: The clinical relevance of this study lies in its evaluation of OPI and its ability to impact the patient experience of clinical care.

Orthopaedic and related care has the potential to present unique obstacles for patients with a range of autism manifestations. In this review, we aim to describe and analyze the literature on autistic patients’ experience within orthopaedics and closely related fields. This literature search utilized the PubMed, Embase, and Cumulative Index to Nursing and Allied Health Literature databases. Three major concepts were built into the search terms: (1) patients on the autism spectrum; (2) patient experience; and (3) movement sciences, including orthopaedics, physical medicine and rehabilitation (PM&R), occupational therapy (OT), and physical therapy (PT). Our search yielded 35 topical publications, with the major topic areas addressed as follows: (1) clinical and perioperative management, (2) therapy interventions, (3) participation in exercise and social play, (4) sensory management and accommodations, (5) caregiver/parent training and involvement in care, (6) healthcare needs and barriers to care, and (7) utilization of technology. In the current literature, there are no studies that attempt to directly assess autistic patient experience with care practices and clinical environments in orthopaedics. Rigorous, direct examination of the experience of autistic patients within clinical orthopaedic settings is urgently needed to address this gap.

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.
