Typical Dislocation Of The Thumb

Illustration from 'Atlas and Epitome of Traumatic Fractures and Dislocations' (by Dr. H. Helferich), 1902. Fig 1 Anatomic specimen of the right hand seen from the volar side. The base of the first phalanx is dislocated to the dorsal side of the head of the first meta curpal bone the capitellum forms a marked prominence the capsule is torn on its flexor surface and displaced dorsally with the first phalanx. We will designate the two sides of the head of the metacarpal bones as the radial and the uluar sides. On the uluar side the adductor poll icis and the tendon of the flexor pollicis longus are wrapped around the neck of the metacarpal bone while on the radial side we find first the flexor pollicis brevis and then thealxluctor pollicis brevis. The capitellum has escaped from between these muscles as through a cleft the tendon of the flexor pollicis longus lies closest to the neck of the metacarpal bone and in the illustration is hidden bchind the capitcllum coming into view again on the volar side of the first phalanx..
