Comparative StudyThe influence of proximal ulnar morphology on elbow range of motion.
Physiologic dorsal apex angulation of the proximal ulna is present in 96% of the population. We hypothesize that a correlation exists between the physiologic dorsal ulnar angulation and elbow range of motion (ROM). ⋯ The increasing magnitude of the PUDA is associated with decreased maximal elbow extension and global elbow ROM.
