Predictors of appointment adherence following operative treatment of pediatric supracondylar humerus fractures: which patients are not following up?

This study aims to identify characteristics associated with poor appointment adherence after surgical stabilization of supracondylar humerus fractures (SCHFX) in children. A retrospective review of 560 consecutive, surgically managed patients with SCHFX from 2010 to 2015 was performed. One missed follow-up appointment was classified as 'low adherence', whereas missing two or more appointments was classified as 'very low adherence'.

Understanding Skeletal Growth and Predicting Limb-Length Inequality in Pediatric Patients.

Limb-length inequality in a child can be a complex condition for patients, parents, and medical providers. Managing these patients and explaining the treatment options to families requires knowledge of the potential risks associated with leaving a discrepancy untreated and a thorough understanding of skeletal growth. The provider must also be familiar with the available growth prediction methods as treatment is influenced by the anticipated discrepancy at skeletal maturity.

Gradual Deformity Correction in Blount Disease.

Background: Blount disease is a disorder of the posteromedial proximal tibial physis which causes a progressive varus, procurvatum, and internal rotation deformity of the tibia. Untreated, it can cause significant limb malalignment. The goal of this study is to evaluate the results of correction of Blount disease using types of external fixation.

Retrograde Stainless Steel Flexible Nails Have Superior Resistance to Bending in Distal Third Femoral Shaft Fractures.

Background: It has been shown that retrograde titanium flexible intramedullary nails (Ti FIN) provide superior resistance to bending compared to antegrade Ti FIN in distal femur fractures. The purpose of this study was to compare resistance to torsional and bending forces of stainless steel (SS) FIN, with or without a locking screw, and Ti FIN in distal third femoral shaft fractures. We hypothesize that locked retrograde SS FIN will demonstrate greater resistance to both bending and torsional forces.

Magnetic Resonance Imaging in Infantile Idiopathic Scoliosis: Is Universal Screening Necessary?

Study Design: Retrospective chart review.

Objective: Determine if there is a subset of presumed infantile idiopathic scoliosis (IIS) patients who have a low incidence of neural axis abnormalities (NAAs) such that screening magnetic resonance imaging (MRI) may be delayed.

Summary Of Background Data: Individuals with presumed IIS have an increased incidence of NAA.

Pediatric Orthopedic Trauma: An Evidence-Based Approach.

The management of pediatric fractures has evolved over the past several decades, and many injuries that were previously being managed nonoperatively are now being treated surgically. The American Academy of Orthopaedic Surgeons has developed clinical guidelines to help guide decision making and streamline patient care for certain injuries, but many topics remain controversial. This article analyzes the evidence regarding management of 5 of the most common and controversial injuries in pediatric orthopedics today.

Squamous cell carcinoma in serous effusions: Avoiding pitfalls in this rare encounter.

Background: With advent of personalized medicine, precise classification of malignant tumors becomes essential. Squamous cell carcinoma (SCC) is rarely found in serous effusions and has morphologic and immunohistochemical (IHC) overlap with other neoplasms.

Methods: 17-year review identified 49 fluids from 26 patients where SCC was recognized.

Acute Intraprosthetic Dissociation of a Dual-Mobility Hip in the United States.

After decades of use in Europe, dual-mobility (DM) components for total hip arthroplasty (THA) were approved by the US Food and Drug Administration (FDA) in 2011 for use in the United States. DM-THAs are designed with an inner articulation between the femoral head and a larger polyethylene insert, and an outer articulation between the mobile polyethylene and a highly polished metal insert, to increase motion and minimize impingement. Intraprosthetic dissociation (IPD), defined as separation of the femoral head from the inner polyethylene articulation, is usually caused by polyethylene wear, and occurs 3 to 10 years after implantation.

Brace Success Is Related to Curve Type in Patients with Adolescent Idiopathic Scoliosis.

Background: Curve magnitude and skeletal maturity are important factors in determining the efficacy of bracing for the treatment of adolescent idiopathic scoliosis, but curve morphology may also affect brace success. The purpose of this study was to determine the influence of curve morphology on the response to bracing with a thoracolumbosacral orthosis (TLSO).

Methods: A retrospective review of patients managed with an orthosis for the treatment of adolescent idiopathic scoliosis who were prospectively enrolled at the initiation of brace wear and followed through completion of bracing or surgery was performed.

Undifferentiated Malignant Neoplasm Involving Parotid and Thyroid: Sampling and PAX8 Cross-Reactivity Can Obscure the Diagnosis of Lymphoma.

Poorly differentiated malignant neoplasia arising within the head and neck region may originate from diverse sources. We report a case of a cytologically undifferentiated malignant neoplasm clinically presenting as masses involving thyroid and parotid. Although PAX8 was immunoreactive and thus worrisome for anaplastic thyroid carcinoma, the tumor was eventually proven to represent PAX5 positive diffuse large B-cell lymphoma expressing cross-reactivity with polyclonal PAX8 antibody.

Extreme lateral interbody fusion for the treatment of adult degenerative scoliosis.

Extreme lateral interbody fusion (XLIF; NuVasive Inc., San Diego, CA, USA) is a minimally invasive lateral transpsoas approach to the thoracolumbar spine. Though the procedure is rapidly increasing in popularity, limited data is available regarding its use in deformity surgery.
