Horner Syndrome Secondary to Osteochondroma of the First Rib: A Case Report.

Osteochondroma is the most common benign tumor of bone that often produces no symptoms unless the enlarged mass affects nearby structures. Rarely, Horner syndrome can be caused by an osteochondroma. A five-year-old female with a past medical history of seizure-like activity presented to the emergency department on three separate occasions within one month.

Prevalence of Bacterial Contamination of Casting Material in a Pediatric Population.

Surgical site infection is a relatively common and devastating complication following pediatric orthopedic surgery. Many infections have been determined to be the result of settled airborne particles on surgical equipment and the sterile field. Fiberglass casts are commonly used orthopedic fixation devices before and after surgery; however, fiberglass casting material is expelled during the removal process and represents an uninvestigated area for the possibility of cast saw dust as a source of airborne bacterial contamination in an operating room setting.

Review article: Patient characteristics that act as risk factors for intraoperative complications in hip, knee, and shoulder arthroplasties.

The number of annual THA's, TKA's, and TSA's is set to increase significantly by the year 2030, making it imperative to understand the risks for negative outcomes in these procedures. While research has studied the patient risk factors for perioperative and postoperative complications, there has been relatively little research for intraoperative complications. After a thorough literature review, the most supported finding was that patients with a BMI >30 had significantly more intraoperative blood loss than those with a BMI <30.

Ultrasound Evaluation of Radial Nerve Palsy Associated with Humeral Shaft Fractures to Guide Operative Versus Non-Operative Treatment.

Objective: To determine the effectiveness of diagnostic ultrasound (US) at evaluating the condition of the radial nerve in the setting of humeral shaft fractures.

Materials And Methods: An observational study was performed of 18 patients with radial nerve palsy associated with humeral shaft fractures who underwent US examination to assess the condition of the radial nerve.

Results: Six patients with humeral shaft fractures treated nonoperatively in a functional brace had US findings consistent with contusion or stretch radial nerve injury.

Review article: Current literature on surgical checklists and handoff tools and application for orthopaedic surgery.

Despite the adaptation of checklists for specific surgeries being developed, there remains a lack of an available standard for an orthopaedic-specific checklist. Benefits of implementing checklists include cost-effectiveness as well as the ability to significantly reduce both mortality and complication rates in a variety of healthcare settings. The aim of this review is to analyze the evidence surrounding the effectiveness of checklists as well as recommend for the development of a standard checklist for specific orthopaedic surgeries such as total joint arthroplasty (TJA).

Case Report of Argininemia: The Utility of the Arginine/Ornithine Ratio for Newborn Screening (NBS).

We describe a case of Argininemia detected by Michigan Newborn Screening (NBS). The Secretary's Advisory Committee on Heritable Disorders in Newborns and Children recommends that every MS/MS newborn screening program include Argininemia as part of their uniform screening panel. While affected infants will be detected by this testing, Arginine levels may take time to accumulate.
