Pregnancy and low back pain

Back pain is ubiquitous in today’s society and is particularly common during pregnancy. There are multiple factors contributing to these symptoms during pregnancy including pelvic changes as well as alterations to loading. Potential imaging modalities are limited during pregnancy due to the desire to limit ionizing radiation exposure to the fetus. Treatments are generally conservative, exercise-based interventions and alternative modalities may also be considered. Low back pain associated with pregnancy does generally resolve postpartum

Ulnar-sided wrist pain. II. Clinical imaging and treatment

Pain at the ulnar aspect of the wrist is a diagnostic challenge for hand surgeons and radiologists due to the small and complex anatomical structures involved. In this article, imaging modalities including radiography, arthrography, ultrasound (US), computed tomography (CT), CT arthrography, magnetic resonance (MR) imaging, and MR arthrography are compared with regard to differential diagnosis. Clinical imaging findings are reviewed for a more comprehensive understanding of this disorder. Treatments for the common diseases that cause the ulnar-sided wrist pain including extensor carpi ulnaris (ECU) tendonitis, flexor carpi ulnaris (FCU) tendonitis, pisotriquetral arthritis, triangular fibrocartilage complex (TFCC) lesions, ulnar impaction, lunotriquetral (LT) instability, and distal radioulnar joint (DRUJ) instability are reviewed

Development of a Pediatric Musculoskeletal Model of the Foot and Ankle

Previously created adult musculoskeletal models (MSMs) have provided insight into the underlying causes of specific gait abnormalities. Since these abnormalities are often diagnosed and treated in children with cerebral palsy, child-specific MSMs are needed. In this study, a child-specific MSM of the foot and ankle was created from existing magnetic resonance images (MRIs) of a child with hemiplegic cerebral palsy and equinovarus disorder. The bony contours of both limbs were digitized and converted into three-dimensional surface meshes. These meshes were used to create the MSM
