Intra- and interobserver reliability for predicting hip preservation versus hip arthroplasty utilizing plain radiographs with comparison of surgeon specialization.

Surgeon subspecialty training and practice landscape are formative in diagnostic evaluation and treatment recommendations. Varying recommendations can have substantial impact on patients' care pathways and outcomes. We investigated intra- and interobserver reliability of treatment predictions for total hip arthroplasty (THA) between surgeons performing arthroplasty and/or arthroscopic hip preservation surgery.

A Novel Screening Technique for Ulnar-Sided Carpometacarpal Dislocations.

Diagnosing ulnar-sided carpometacarpal joint dislocation is difficult, and more than half of injuries are missed on initial examination. The authors hypothesized that measuring the angle between the capitate and the metacarpals (capitate-metacarpal angle) on a plain radiograph would provide a simple, reliable tool to aid in the diagnosis of ulnar-sided carpometacarpal dislocation. This study retrospectively reviewed patients who underwent surgery for ulnar-sided carpometacarpal dislocation (study group).

Intra-Articular Dislocation of the Patella With Associated Hoffa Fracture in a Skeletally Immature Patient.

Since 1887, approximately 50 cases of an intra-articular patellar dislocation have been reported in the worldwide literature. The vast majority of patients required an open reduction of the patella or closed reduction under general anesthesia. This injury has never been reported in association with a coronal shear fracture of the femoral condyle.

Staged treatment of a chronic patellar sleeve fracture using the Taylor spatial frame.

Patellar sleeve fractures are easily missed injuries since plain radiographs may not show a bony fragment at the time of injury. Failure to diagnose these injuries can result in patellar instability, extensor lag, and anterior knee pain. We report a novel treatment using a Taylor spatial frame as part of a staged reconstruction to regain length of the extensor mechanism and maintain knee motion prior to performing primary repair of the avulsed patellar sleeve fragment.

Complications associated with hinged external fixation for chronic elbow dislocations.

Purpose: To evaluate the outcomes of patients who underwent application of hinged external fixators for chronic elbow fracture-dislocations. We hypothesized that patients treated for this injury pattern can achieve satisfactory outcomes but encounter many complications and require numerous additional procedures.

Methods: We performed a retrospective review of 7 patients who were surgically treated with application of a hinged external fixator for chronic ulnohumeral elbow fracture-dislocation.

Repeat emergency room visits for hand and wrist injuries.

Purpose: To characterize patients with hand or wrist injuries presenting to our university-based emergency department (ED) after a previous evaluation by an outside ED. We hypothesized that a majority of these patients did not require emergent care, most arrived during working hours, and a disproportionate number were uninsured.

Methods: We retrospectively reviewed 3,047 orthopedic hand consults from 2002 to 2010.

Sequelae of foreign bodies in the wrist and hand.

Background: Penetrating injuries to the hand are a common occurrence in the emergency room, and embedment of foreign bodies is suspected in many of these cases. The existing literature offers little information on retained foreign bodies. The aim of this study was to identify characteristics, determine prevalence, and observe outcomes for retained foreign bodies in the wrist and hand.

Volar dislocation of the thumb metacarpophalangeal joint with acute repair of the ulnar collateral ligament.

Volar dislocations of the thumb metacarpophalangeal joint are uncommon and can be associated with rupture of the ulnar collateral ligament (UCL). We report a case where a volar thumb dislocation was successfully closed reduced, but instability required open repair of the UCL. Early motion protocol helped achieve favorable results.

Disruption of ATP-binding cassette B8 in mice leads to cardiomyopathy through a decrease in mitochondrial iron export.

Mitochondrial iron levels are tightly regulated, as iron is essential for the synthesis of Fe/S clusters and heme in the mitochondria, but high levels can cause oxidative stress. The ATP-binding cassette (ABC) transporter ABCB8 is a mitochondrial inner membrane protein with an unknown function. Here, we show that ABCB8 is involved in mitochondrial iron export and is essential for baseline cardiac function.

Lateral femoral cortical breach during anterior cruciate ligament reconstruction: a biomechanical analysis.

Purpose: The purpose of our study was to determine whether secondary fixation is needed when lateral femoral wall breach occurs and whether the diameter of the femoral tunnel affects the cyclical and ultimate load to failure of 3 different suspensory fixation devices.

Methods: Sixty fresh-frozen porcine femora were dissected to isolate the anterior cruciate ligament (ACL) footprint. Femoral ACL tunnels were then drilled at diameters of 7, 8, 9, and 10 mm.

Commercial products that convey personal health information in emergencies.

Objective: Describe commercially available products and services designed to convey personal health information in emergencies.

Methods: The search engine Google®, supplemented by print ads, was used to identify companies and organizations that offer relevant products and services to the general market. Disease-specific, health system, and health plan-specific offerings were excluded.
