Extensor Muscles Of The Thumb - Everything You Need To Know - Dr. Nabil Ebraheim

Dr. Ebraheim’s educational animated video describes the anatomy of the extensor muscles. There are three extensors of the thumb: the extensor pollicis longus, extensor pollicis brevis, and abductor pollicis longus. The three tendons inserted into the thumb are abductor pollicis longus, extensor pollicis brevis and extensor pollicis longus. The extensor pollicis brevis – shorter. It comes from the radius and inserts into the proximal phalanx of the thumb. The extensor pollicis longus – longer. It comes from the ulna and inserts into the distal phalanx of the thumb. The abductor pollicis comes from both the ulna and radius and inserts into the base of the 1st metacarpal bone. The extensor indicis tendon may be transferred to replace a torn EPL tendon. The patient cannot extend the thumb due to a ruptured EPL tendon. The extensor indicis tendon may be used as a tendon transfer from its insertion into the index finger to restore the function of the thumb due to a ruptured extensor pollicis longus tendon.
