From Hip to Heart: A Comprehensive Evaluation of an Infiltrative Cardiomyopathy.

Infiltrative cardiomyopathies are an increasingly recognized cause of heart failure warranting systematic evaluation. Given overlap of clinical and imaging findings among etiologies of infiltrative cardiomyopathies, comprehensive evaluation, including a history and physical examination, advanced cardiac imaging, and sometimes endomyocardial biopsy, is required for diagnosis. We report a case of infiltrative cardiomyopathy in which endomyocardial biopsy confirmed diagnosis of cobalt-induced cardiomyopathy.

Bilateral acetabular fractures treated with delayed total hip arthroplasty.

Acetabular fractures after seizures are uncommon, and fewer than 30 cases are described in the literature. We present a patient with bilateral acetabular fractures after a seizure, with bilateral quadrilateral plate destruction and protrusio deformity. The patient underwent delayed staggered bilateral total hip arthroplasty 3 months after initial injury, with use of the femoral head as autograft for the protrusio deformities.

Sensitivity of magnetic resonance imaging in the diagnosis of mobile and nonmobile L4-L5 degenerative spondylolisthesis.

Background Context: Lumbar degenerative spondylolisthesis (LDS) is often diagnosed by conventional supine magnetic resonance imaging (MRI). Numerous studies have shown, however, that the degree of spondylolisthesis can be reduced or disappears when the patient is supine as compared with standing lateral and flexion-extension (SLFE) radiographs.

Purpose: To compare the sensitivity of supine MRI with SLFE radiographs in patients with L4-L5 LDS.
