Presence of Multiple Tendinous Insertions of Palmaris Longus: A Unique Variation of a Retrogressive Muscle
نویسندگان
چکیده
BACKGROUND Palmaris longus, being the most variable muscle of the upper extremity is generally considered important morphologically rather than functionally. The palmar aponeurosis represents the distal part of the tendon of Palmaris longus. CASE DETAILS We report here a unique case of palmaris longus presenting variation distally as its tendon divides to gain multiple attachments with the fascia covering the abductor pollicis brevis, flexor retinaculum and the tendon of flexor carpi ulnaris. In addition, it also continues as palmar aponeurosis as its normal course. CONCLUSION Presence of this kind of variation might result in compression of the median and ulnar nerves and may aggravate the complications in case of inflammation of palmar aponeurosis thus mimicking the manifestations of Dupuytren's contracture.

Variation, Length and Width of Tendinous Portion of Palmaris Longus and Forearm Length and Height: Is there a link? A Cadaver Study of Adult Iranians
Background: Palmaris longus (PL) is a muscle with marked variations. It is harvested as a tendon graft in many surgical proceduresin which a certain length of tendon is required. The aims of the present study were to determine the variations of this tendon in Iranian population and to find whether the length of PL tendon could be estimated by measuring the forearm length and height. Methods: We...

We report a case of bilateral reversed palmaris longus muscle (PLM). The muscle was tendinous in its upper portion and muscular in its lower portion in both arms. This rare variation has been mentioned only once in the literature as a surgical finding. According to the literature, a reversed PLM may cause a compartment syndrome in the wrist area, carpal tunnel, and Guyon's syndrome. The des...
