“…The percentage of agenesis of the PL muscle in our case was greater than that reported by Kigera & Mukwaya in corpses in Southern Africa, similar to that reported by Thompson et al (2001) in Caucasian subjects in Northern Ireland (16 %), lower than that reported by Alves et al (2011) in Chilean adults, and lower than that reported by Ceyhan & Mavt in Indians. The differences in the incidences may be associated with the ethnic origin of the subjects.…”

of the tendons of the palmaris longus and radial carpal extensor muscles in humans. Int. J. Morphol., 34(4):1515Morphol., 34(4): -1521Morphol., 34(4): , 2016. SUMMARY:The tendons of the palmaris longus (PL) and radial carpal extensor (RCE) muscles have extensive applications in surgery, yet despite their constant use, information about their morphological and morphometric characteristics remains limited. The aim of this study was to describe the morphological and morphometric characteristics of the PL and RCE muscle tendons and compare them to each other in 30 upper limbs of adult individuals with no apparent deformations from anatomy units at four universities in Chile. The anterior side and lateral margin of the forearm and the back of the hand as far as the tendon plane were dissected. The average length, width at origin level and at the level of the radiocarpal joint line of the PL muscle tendon were 125.48 mm ± 8.93, 4.76 mm ± 1.35 and 3.76 mm ± 0.91, respectively. The average length, width at the levels of origin and insertion of the extensor carpi radialis longus muscle tendon were 180.46 mm ± 15.03, 14.69 mm ± 3.72 and 7.76 mm ± 1.44 respectively, whereas for the extensor carpi radialis brevis muscle they were 115.23 mm ± 11.81, 9.53 mm ± 2.58 and 7.33 mm ±1.17, respectively. The most common origin of the tendons of the PL and extensor carpi radialis longus muscles was at the level of the middle third of the forearm, whereas the most common origin of the extensor carpi radialis brevis muscle tendon was at distal third level. The shape of the tendons of the PL and RCE muscles was broad and flat along their entire length. Simulating the longitudinal division of the tendons of the RCE muscles in two halves, the radial half of the tendons of both muscles has morphological and morphometric characteristics similar to the PL muscle tendon, such that it could be used as a graft in the case of agenesis of the PL muscle, or for tendon transfer where elongation of a tendon in the region is required.KEY WORDS: Palmaris longus muscle; Extensor carpi radialis muscles; Extensor carpi radialis longus muscle; Extensor carpi radialis brevis muscle; Upper limb; Tendon transfer surgery.

ObjectiveDemonstrate that the tendon of palmar long can be estimated in relation to its length and width before using it as a graft in surgical procedure.MethodsThere were examined 60 forearms of 30 corpses of black ethnicity; measure the length and width of the tendon of the palmaris longus muscle and compared the length of the forearm.ResultsThere are notes their absence unilateral right in two female corpses. The medium length and width were more or less respectively 11.9, 15.2 mm and 4.1 + 1.5 mm. The total average forearm length of 275.4 was more or less 17.9 mm.ConclusionThere is a significant relationship between the length of the tendon and the length of the forearm; so we can evaluate the size of the tendon of the palmaris longus muscle when it is necessary to use it for grafts. Levels of Evidence IV, Case series.

“…In 1559, the absence of Palmaris longus muscle was described or the first time in Columbus' book, which was published soon after his death [15]. Several clinical trials an studies have been conducted since y many authors [16][17][18][19][20]. The absence of this muscle and tendon has also been reported in different ethnic groups, with wide variation [16][17][18][21][22][23].…”

Palmaris longus (PL) is one of the most variable and most superficial flexor muscles of the forearm. Plantaris muscle has also been observed to present frequent variations in terms of its occurrence, origin, course, relation with surrounding neurovascular structures and insertion. Materials and Methods: The study consisted of a total of 100 upper limbs and 100 lower limbs out of the total 50 bodies. The origin, insertion, nerve and blood supply were noted. The length, circumference of the muscle belly and the tendon were also noted for both the muscles. Results: The length of the forearm, Palmaris longus muscle and the tendon was also more in the males than in the females. &% of the cases had agenesis of the Palmaris longus muscle. High aponeurosis, twin bellies of the muscle, extra origin of the Palmaris longus muscle from the inter muscular septum and flexor digitorum superficialis muscle were some of the variations observed. In case of the Plantaris muscle, the length was more in the females than in the males, though the circumference of the belly and the length of the tendon was far higher in the males than in the females. Conclusion: The knowledge of the approximate length and breadth of the Palmaris and the plantaris muscle, including the various variations that may be associated with it is very important to the surgeons in various reconstructive surgeries and physiotherapies
