(pahl'maris long'gŭs mŭs'ĕl) [TA]
Muscle of superficial layer of anterior (flexor) compartment of forearm; origin, medial epicondyle of humerus; insertion, flexor retinaculum of wrist and palmar fascia; action, tenses palmar fascia and flexes the hand and forearm; nerve supply, median.

The donor site morbidity of the Osseo-cutaneous was acceptable with low rates of complications.3 Radial forearm free flap have been used extensively for lip reconstruction, Palmaris longus sling have been associated with the flap for achieving goals like oral continence, speech and mastication and excellent results have been achieved.4
Nerve transfers to restore wrist and fingers extension has been reported using donors such as median nerve branches to the pronator teres (PT), flexor carpi radialis (FCR), palmaris longus (PL), and flexor digitorum superficalis (FDS); anterior interosseous nerve (AIN) branches to the pronator quadratus (PQ), and radial nerve branches to the supinator (Sukegawa et al.; Ray & Mackinnon; Ukrit et al., 2009; Bertelli & Ghizoni, 2010; Lowe et al.; Ustun et al).
While this may be found earlier, this is typically seen in injuries that are more than 6 weeks old, and when present these cases can be treated with tendon transfers or graft reconstruction using palmaris longus or EPB autografts, among others.
Stimulation is given for median nerve at the wrist between Palmaris longus and flexor carpi radialis (FCR).
Palmaris longus (PL) is a thin muscle which originates from the medial epicondyle by a short belly, located superficially in the middle of the anterior aspect of the forearm.
Unusual combination of muscular and arterial variations in the upper extremity: a case report of a variant palmaris longus and an additional tendinous portion of the flexor carpi ulnaris together with a persistent median artery.
For reconstruction of the tendon or the ligament, following dissection of palmaris longus tendon and then veins toward the proximal part of the forearm which should occupy in the central part of the flap, superficial veins were also dissected from the distal to the volar wrist line toward the thenar region and included in the flap.
The site of stimulation was at the wrist between the palmaris longus and flexor carpi radialis tendon at the second crease and at the elbow crease, medial to the biceps tendon, and the brachial artery.
Valgus osteotomy was performed in the distal humerus through a lateral wedge and ligament reconstruction with tendon graft of the autologus palmaris longus, by tunneling the distal humerus and ulna crest.
Abstract: The aim of the study is to generate control signals from surface Electromyography signals (EMGs) measured from four hand muscles; Extensor carpi radialis, Palmaris longus, Pronator quadratus and Flexor digitorum superficialis to navigate a prosthetic hand.
In supine position with arm in the side table via volar approach under fluoroscopic guidance between palmaris longus and flexor carpi radialis the wrist was opened.
