Palpation of soft tissue

Place one finger just radially to the dorsal tubercle of the radius. Ask the subject to make a first and to squeeze and unsqueeze it. During this action tendinous tightening can be felt. These are the tendons of the extensor carpi radialis longus and extensor carpi radialis brevis. When the subject continues these muscular contractions […]

Hand Injuries

The metacarpals in the middle of the hand have very little motion and provide a stable palm, while the little finger and especially the thumb have significantly more motion to […]

Dislocation of Finger Joint

SYMPTOMS

There is intense localised pain and deformation (bayonet position, where distal phalanx is retracted over the dislocated joint by flexor tendons) of a meta-carpo-phalangeal (MCP), proximal inter-phalangeal joint (PIP) or distal inter-phalangeal (DIP) joint after direct trauma from a hard ball or a fall on a stretched-out finger.

AETIOLOGY

One or more […]

Baseball Mallet Finger

AETIOLOGY

This injury is a rupture of the most distal insertion of the extensor digitorum […]
