Improving Medical Student Mentorship in Orthopaedic Surgery.

Introduction: Owing to limited clinical clerkships and travel restrictions related to COVID-19, recent medical student mentorship in orthopaedic surgery has been impacted negatively. The purpose of this quality improvement (QI) project was to determine if medical student awareness of orthopaedics as a possible career field may be improved through a mentoring program designed and delivered by orthopaedic residents.

Methods: A five-resident QI team developed four educational sessions aimed at a medical student audience.

Supraspinatus Fatty Infiltration Correlation with Handgrip Strength, Shoulder Strength, and Validated Patient-Reported Outcome Measures in Patients with Rotator Cuff Tears.

Introduction: The purpose of this study was to investigate the relationships between supraspinatus atrophy on magnetic resonance imaging (MRI) and other objective parameters in patients with rotator cuff tears. It was hypothesized that high-grade supraspinatus fatty infiltration would be correlated negatively with handgrip strength, shoulder strength, and patient-reported outcome measures (PROMs).

Methods: Patients with MRI-proven rotator cuff tears treated by a single sports medicine fellowship-trained orthopaedist at a single institution underwent comprehensive preoperative evaluation including bilateral handgrip and shoulder strength measurements with dynamometers and multiple online questionnaires from the Surgical Outcomes SystemTM (Arthrex, Naples, FL).

Improving Electronic Patient Handoff in an Orthopaedic Residency using the Listrunner Application.

Introduction: Miscommunication during shift change and other handoff events is a common source of malpractice claims and patient-care errors. An efficient patient handoff system is imperative to prevent miscommunication. Owning to limitations with our current handoff system and to an ever-increasing reliance on electronic health information, our residency program sought to modernize our handoff method.

Creating and Implementing a Protocol for the Management of Patients in Skeletal Traction: A Quality Improvement Project.

Introduction: Skeletal traction use generally has decreased over generations and is used most often for temporary fracture stabilization. Proper nursing management of patients in skeletal traction is crucial. A hospital protocol was created and implemented to educate and direct registered nurses (RNs) in the care of patients requiring skeletal traction.

Treatment of Femoral Shaft Fractures in Patients with Klippel-Trénaunay Syndrome: A Report of 2 Cases.

Cases: Long-bone fractures in patients with Klippel-Trénaunay syndrome (KTS), a rare disorder of the venous, lymphatic, and capillary system, are difficult to treat with many complications. Two patients diagnosed with KTS presented with closed femoral shaft fractures after low-energy falls. Conservative treatment, open reduction internal fixation, and intramedullary nailing resulted in painful nonunions.

Aspirin for Prophylaxis Against Venous Thromboembolism After Orthopaedic Oncologic Surgery.

Background: Patients who undergo orthopaedic oncologic surgical procedures are at increased risk of developing a venous thromboembolism (VTE). Guidelines from surgical societies are shifting to include aspirin as a postoperative VTE prophylactic agent. The purpose of this study was to review our experience using aspirin as postoperative VTE prophylaxis for orthopaedic oncologic surgical procedures.

Dinoflagellate Gene Structure and Intron Splice Sites in a Genomic Tandem Array.

Dinoflagellates are one of the last major lineages of eukaryotes for which little is known about genome structure and organization. We report here the sequence and gene structure of a clone isolated from a cosmid library which, to our knowledge, represents the largest contiguously sequenced, dinoflagellate genomic, tandem gene array. These data, combined with information from a large transcriptomic library, allowed a high level of confidence of every base pair call.

Mini-open versus extended open release for severe carpal tunnel syndrome.

Background: This study aims to compare surgical outcomes of severe carpal tunnel syndrome (CTS) treated with mini-incision versus extensile release.

Methods: The method employed in this study was a retrospective review of patients with severe CTS, defined by electrophysiologic studies showing non-recordable distal sensory latency of the median nerve. Patients underwent either a mini-incision (2 cm) release of the transverse carpal ligament (group 1) or extensile release proximal to the wrist flexion crease (group 2).

Dinoflagellate phylogeny revisited: using ribosomal proteins to resolve deep branching dinoflagellate clades.

The alveolates are composed of three major lineages, the ciliates, dinoflagellates, and apicomplexans. Together these 'protist' taxa play key roles in primary production and ecology, as well as in illness of humans and other animals. The interface between the dinoflagellate and apicomplexan clades has been an area of recent discovery, blurring the distinction between these two clades.

A geochemical approach to determine sources and movement of saline groundwater in a coastal aquifer.

Geochemical evaluation of the sources and movement of saline groundwater in coastal aquifers can aid in the initial mapping of the subsurface when geological information is unavailable. Chloride concentrations of groundwater in a coastal aquifer near San Diego, California, range from about 57 to 39,400 mg/L. On the basis of relative proportions of major-ions, the chemical composition is classified as Na-Ca-Cl-SO4, Na-Cl, or Na-Ca-Cl type water.
