Absence of the palmaris longus muscle: a population study.
We examined 300 Caucasian subjects (150 males, 150 females) aged 18-40 years to assess the incidence of palmaris longus absence. The presence or absence of palmaris longus was assessed by clinical inspection. Forty-nine subjects had unilateral absence of palmaris longus (16%). The tendon was absent bilaterally in 26 subjects (9%). Unilateral and bilateral absence was more common in males, howev...
متن کاملMorphology of human palmaris longus tendon.
A systematic morphological investigation of human palmaris longus tendons by polarisation microscopy and low angle x-ray diffraction is reported. It is shown that contrary to some previously reported observations, and in common with other tension bearing soft collagenous tissues, the fibres in this tendon are crimped. A new method of preparation of the tissue enabling one to see directly the cr...
متن کاملA Case of the Bilateral Duplicate Palmaris Longus Muscles Coupled with the Palmaris Profundus Muscle
The palmaris longus muscle is one of the most variable muscles in human anatomy. During a routine anatomical dissection for medical students at Tottori University, we found duplicate palmaris longus muscles in the bilateral forearms together with the palmaris profundus muscle in the right forearm. The bilateral aberrant palmaris longus muscles were observed at the ulnar side of the palmaris lon...
متن کاملMorphometric and Statistical Analysis of the Palmaris Longus Muscle in Human and Non-Human Primates
The palmaris longus is considered a phylogenetic degenerate metacarpophalangeal joint flexor muscle in humans, a small vestigial forearm muscle; it is the most variable muscle in humans, showing variation in position, duplication, slips and could be reverted. It is frequently studied in papers about human anatomical variations in cadavers and in vivo, its variation has importance in medical cli...
متن کاملAn unusual duplication of the palmaris longus muscle
Introduction The palmaris longus muscle is one of the most variable muscles in the human body [1] . It usually arises from the common flexor origin at the medial epicondyle of the humerus, and from the intermuscular septum. It inserts into the central palmar surface of the palmar aponeurosis. The palmaris longus is an important muscle for hand surgeons as it is commonly used in tendon graft and...
