Pemphigus," he added carelessly, pointing to the woman's disfigured hands. "Would you care to stop and take out a metacarpal?" "No, thank you. We are due at Archer's. Come on!" and they rejoined the throng which was hurrying to the theatre of the famous surgeon.
The anterior portion of the capsular ligament forms sheaths for the extensor tendons, and both portions of the joint have an attachment around the distal end of the radius and another at the proximal end of the metacarpal bones. Etiology and Occurrence.
When a toe is affected, amputation is the best treatment, but in the case of a finger it is rarely called for. In the case of a metacarpal or metatarsal bone, sub-periosteal resection is the procedure of choice, saving the articular ends if possible. [Illustration: FIG.
Although each of the wrist bones has a very limited mobility in relation to its neighbors, their combination gives the hand that freedom of action upon the wrist, which is manifest in countless examples of the most accurate and delicate manipulation. The metacarpal bones are the five long bones of the back of the hand.
There is a long bone, termed 'metatarsal', answering to the metacarpal, for each digit; and the 'tarsus', which corresponds with the carpus, presents four short polygonal bones in a row, which correspond very closely with the four carpal bones of the second row of the hand. In other respects the foot differs very widely from the hand.
He gritted his teeth when he swung back the single-jack and landed a glancing blow on the knuckles of his left hand instead of the drill end. No man save Casey Ryan or a surgeon could have told positively whether the metacarpal bones were broken or whether the hand was merely skinned and bruised.
The principal metacarpal and metatarsal bones are flatter than they are in any of the Equidoe; and the metacarpal bones are longer than the metatarsals, as in the Paloeotheria. In its general form, Plagiolophus resembles a very small and slender horse, and is totally unlike the reluctant, pig-like creature depicted in Cuvier's restoration of his Paloeotherium minus in the "Ossemens Fossiles."
No form of drain should be inserted. In the fingers the incisions should be made in the middle line, and in the palm they should be made over the metacarpal bones to avoid the digital vessels and nerves. If pus has spread under the transverse carpal ligament, the incision must be made above the wrist.
Horses that are "knee sprung" or that have a congenital condition where in the anterior line, as formed by the radius, carpal and metacarpal bones, is bent forward at the carpus, are subject to inflammation and contraction of the carpal flexors. When these flexors are contracted, the condition is commonly known among horsemen as "buck knee." Symptomatology.
Perfect apposition of the broken ends of bone is easily effected and less difficulty is encountered in maintaining such relations in metacarpal fractures than in fractures of the radius. However, reduction and immobilization of this as in all fractures, must be done without delay.
