The Use of Ultrasound to Exclude Extremity Fractures in Adults.

Background: The purpose of the present study was to investigate whether ultrasonography can be used as a diagnostic tool to exclude extremity fractures in adults.

Methods: This prospective comparative study involved 91 patients (age, ≥18 years) who had been referred by general practitioners for a conventional radiographic examination of a suspected extremity fracture. No additional clinical examination was performed.

Pain profiling of patients with temporomandibular joint arthralgia and osteoarthritis diagnosed with different imaging techniques.

Background: Clinical differentiation between pain mechanisms of temporomandibular joint (TMJ) arthralgia and osteoarthritis (OA) is challenging. The aims were to compare somatosensory function at the TMJs and conditioned pain modulation (CPM) effects between TMJ arthralgia and OA patients diagnosed clinically and based on different imaging techniques and age- and gender-matched healthy controls (n = 41).

Methods: Patients (n = 58) underwent standard clinical examination and three different TMJ imaging modalities.
