Clinical and radiographic predictors for angiography in pelvic trauma: An analysis of 1703 patients.

Introduction: Patients who present with hemorrhage from pelvic fractures have an increased risk of mortality with prolonged time to intervention. Identifying risk factors associated with hemorrhage can expedite treatment. In this study we explore clinical and radiographic predictors for angiography in trauma patients with pelvic fractures.

Atypical Shoulder Instability Patterns in Adolescents Following Traumatic Anterior Shoulder Dislocation.

Background: Traumatic anterior shoulder instability is common in the adolescent athlete, and when it is untreated, the recurrence rate is high. Atypical lesions-such as anterior glenoid periosteal sleeve, humeral glenohumeral ligament, and insertional tendon avulsions-may occur within this population, and accurate diagnosis and appropriate lesion management are key to treatment success.

Purpose: To evaluate the age, skeletal immaturity, bone loss, and uncommon soft tissue lesions as correlates of posttraumatic anterior shoulder instability lesion patterns in an adolescent population.

Clinical and Radiographic Presentation of Capsular Iatrogenic Hip Instability After Previous Hip Arthroscopy.

Background: The clinical and radiographic features of iatrogenic hip instability following hip arthroscopy have been described. However, the prevalence of presenting symptoms and associated imaging findings in patients with hip instability has not been reported.

Purpose: To detail the prevalence of clinical and magnetic resonance arthrogram (MRA) findings in a cohort of patients with isolated hip instability and to determine midterm patient-reported outcomes in this patient population.

Traumatic Pediatric Quadriceps Rupture After Medial Patellofemoral Ligament Reconstruction: A Case Report.

Case: A healthy 14-year-old boy, who presented with recurrent patellar instability, underwent medial patellofemoral ligament (MPFL) reconstruction. Four weeks following this operation, the patient slipped and fell while wearing his knee brace and was found to have sustained a quadriceps tendon rupture.

Conclusions: We present a case of a rare, previously undescribed complication following an MPFL reconstruction in a young athlete.

Knee Extension Does Not Reliably Reduce Acute Type II Tibial Spine Fractures: MRI Evaluation of Displacement During Extension Versus Resting Flexion.

Background: Type II tibial spine avulsion (TSA) fractures have traditionally been managed by first attempting to achieve closed reduction with extension and immobilization, with surgical indications reserved for those who fail to reduce within 3 mm. However, the frequency with which appropriate reduction can be achieved is largely unknown.

Purpose: To evaluate changes in displacement of type II TSA fractures by comparing magnetic resonance imaging (MRI) scans obtained with the knee in flexion and in extension.
