The value of the pronated-grip view radiograph in assessing dynamic ulnar positive variance: a case report
1Department of Orthopaedic Surgery, Washington University School of Medicine, St. Louis, Missouri, USA.
Abstract:
Positive ulnar variance affects surgical decision making when ulnar wrist pain is refractory to conservative treatment and is either secondary to a posttraumatic triangular fibrocartilage tear or associated with ulnar impaction syndrome. In such settings, ulnar recession may be necessary to diminish load transmission across the ulnocarpal joint. We present a case of a 24-year-old man with chronic right ulnar wrist pain that illustrates the efficacy of the pronated-grip radiograph in assessing dynamic ulnar positive variance.

Assessment of radial pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:
Assessment of apical radial pulse
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.
