Anatomic description of the Palmaris longus muscle and report of variant nerve supply in the white‐footed tamarin (Saguinus leucopus Günther, 1876)
Journal of Medical Primatology, 2018Co-Authors: Juan Fernando Vélez-garcía, Jorge Eduardo Duque-parra, John Barco-ríosAbstract:The gross anatomy of the Palmaris longus muscle in 12 specimens of Saguinus leucopus was studied by dissection. This muscle was constant and unipennate, originated in the medial epicondyle of the humerus; inserted onto flexor retinaculum and Palmar Aponeurosis; and innerved by the median nerve, and in one case, together with the ulnar nerve. This is the first report of double innervation for this muscle in primates.

A new tendon transfer for ulnar clawhand: use of the Palmaris longus extended with the Palmar Aponeurosis.
The Journal of hand surgery, 1992Co-Authors: N. Ochiai, Akira Nagano, Yuji Mikami, Tanefumi Nakagawa, Seizo YamamotoAbstract:A new tendon transfer for ulnar paralytic clawhand, in which the Palmaris longus with distal extensions of the Palmar Aponeurosis is passed under the transverse carpal ligament and fixed to the A-1 pulley of the small and ring fingers, is described. Advantages of the procedure are that there is no loss of function and free tendon grafts are not needed.

bilateral reversed Palmaris longus muscle with trifid insertion a rare variation
International Journal of Research in Medical Sciences, 2014Co-Authors: Anita Rahul Gune, Anand J Pote, Ashalata D Patil, Priya S Patil, Vasudha R NikamAbstract:Normally the Palmaris longus muscle originates from the medial epicondyle of the humerus from common flexor origin. In the middle of the forearm, the muscle belly forms a tendon which is inserted into the flexor retinaculum and the Palmar Aponeurosis. In our study after dissection of both forearms of a 45-year-old male cadaver we found a reversed Palmaris longus muscle. This means that the Palmaris longus muscle was tendinous in its proximal part and muscular in its distal part. The fleshy belly of muscle was passing over flexor retinaculum, was ensheathed by separate fascia. The muscle belly was spreading on both the sides of each palm for insertion which was trifid, that is centrally into Palmar Aponeurosis, laterally continuous with the fascia covering the thenar muscles and medially with Abductor digit minimi. It was having tendinous interconnection with the muscle mass of both the sides. Bilateral reversed Palmaris longus muscle mentioned in the literature, was a surgical finding in a patient who suffered from edema and pain in the wrist. The overuse of the reversed Palmaris longus muscle can lead to the muscle’s local hypertrophy. As per the literature a reversed Palmaris longus muscle may cause a compartment syndrome with pain and edema in the wrist area, the carpal tunnel syndrome and Guyon’s syndrome. The variation is also useful to the hand surgeon, as the Palmaris longus muscle is an anatomical landmark for operations in this area.

The surgical treatment of Dupuytren's contracture
Chinese Journal of Hand Surgery, 2011Co-Authors: Xiao-nan Wang, Ke-jun Chen, Bao-ping Han, Shi-lian KanAbstract:Objective To investigate a modified technique in the surgical treatment of Dupuytren' s contracture and its clinical outcomes. Methods Eleven cases in 9 patients of Dupuytren's contracture were treated by partial resection of the Palmar Aponeurosis from September 2008 to August 2009. The conventional method was modified by treating the skin flap as a skin graft. Results Primary wound healing was achieved in all cases. There was no infection, hematoma or skin necrosis. The follow-up period ranged from 1 to 6 months,with an average of 3.3 months. There was no recurrence. The results were graded as good in 9 cases and fair in 2 cases according to the upper limb functional evaluation criteria issued by the Hand Surgery Society of the Chinese Medical Association. The overall satisfactory rate was 100%. Conclusion Early postoperative complication rate can be greatly reduced by treating Palmar skin flap as free skin graft after partial resection of the Palmar Aponeurosis. Key words: Surgical flaps; Dupuytren's contracure; Skin graft
