OBJECTIVE The senior author previously reported a case of rupture of the flexor policis longus tendon after volar plating of a distal radius fracture. We hypothesized that restoration of the pronator quadratus to its native position after plating might prevent this problem. METHODS The authors report a new case of irritation of the flexor policis longus 2.5 years after volar plating of a dist...

UNLABELLED   BACKGROUND The prevalence of the palmaris longus agenesis (PLA) has been variously reported to be from 1.5% to 64% in different ethnic groups. Lack of reliable information about the state of the PLA in Iran made us to design a study on the agenesis of the palmaris longus (PL) among a sample of Iranian population during 2009. MATERIALS AND METHODS One thousand participants were ...

The Palmaris longus muscle (PLM) is a slender, fusiform muscle which lies on the flexor surface of the forearm. Its agenesis is considered the most frequent anatomic variation in the muscular system of the human body. The PLM has little functional use to the human upper limb. It is evidenced by former epidemiological studies that the agenesis of the PLM has a strong racial and ethnic variabilit...
