We know as _false crepitation_ a vibrating impulse occasioned by normal contact of articular portions of bones such as in the metacarpophalangeal joint when this structure is passively moved, where the subject permits the parts to remain in a state of complete relaxation. ❋ John Victor Lacroix (N/A)
Where a complete luxation of the metacarpophalangeal joint exists, it is probable that in most cases sufficient injury to collateral and capsular ligaments has been done to render complete recovery improbable, if not impossible. ❋ John Victor Lacroix (N/A)
Therefore, it is a natural sequence that the tendon sheaths of the metacarpophalangeal region are frequently distended because of chronic synovitis and thecitis. ❋ John Victor Lacroix (N/A)
The metacarpophalangeal articulation (fetlock joint), is a hinge joint and its articular surfaces contact one another, with respect to their having a long bearing surface from side to side, as do all ginglymus ❋ John Victor Lacroix (N/A)
The metacarpophalangeal and interphalangeal joints are readily available for surface examination; the former are situated just distal to the prominences of the knuckles, the latter are sufficiently indicated by the furrows on the volar, and the wrinkles on the dorsal surfaces. ❋ Unknown (1918)
Two, of which the medial is the the larger, are constant at the metacarpophalangeal joint of the thumb; one is frequently present in the corresponding joint of the little finger, and one (or two) in the same joint of the index finger. ❋ Unknown (1918)
To the tubercles on the digital extremities are attached the collateral ligaments of the metacarpophalangeal joints. ❋ Unknown (1918)
It is blended with the volar (glenoid) ligaments of the metacarpophalangeal articulations. ❋ Unknown (1918)
Flexion of the metacarpophalangeal joint of the thumb is effected by the Flexores pollicis longus and brevis; extension by the Extensores pollicis longus and brevis. ❋ Unknown (1918)
One of these, starting in front of the wrist at the tuberosity of the navicular bone, curves around the thenar eminence and ends on the radial border of the hand a little above the metacarpophalangeal joint of the index finger. ❋ Unknown (1918)
In addition to this the Interossei, in conjunction with the Lumbricales, flex the first phalanges at the metacarpophalangeal joints, and extend the second and third phalanges in consequence of their insertions into the expansions of the Extensor tendons. ❋ Unknown (1918)
Sesamoid bones are also found occasionally at the metacarpophalangeal joints of the middle and ring fingers, at the interphalangeal joint of the thumb and at the distal interphalangeal joint of the index finger. ❋ Unknown (1918)
Opposite the metacarpophalangeal articulation each tendon is bound by fasciculi to the collateral ligaments and serves as the dorsal ligament of this joint; after having crossed the joint, it spreads out into a broad aponeurosis, which covers the dorsal surface of the first phalanx and is reinforced, in this situation, by the tendons of the Interossei and Lumbricalis. ❋ Unknown (1918)
On either side of the head is a tubercle for the attachment of the collateral ligament of the metacarpophalangeal joint. ❋ Unknown (1918)
The arrangement of these ligaments is similar to those in the metacarpophalangeal articulations. ❋ Unknown (1918)
Each passes to the radial side of the corresponding finger, and opposite the metacarpophalangeal articulation is inserted into the tendinous expansion of the Extensor digitorum communis covering the dorsal aspect of the finger. ❋ Unknown (1918)
In many cases (52 per cent.) a slip is continued from the insertion of the tendon anteriorly over the Opponens digiti quinti, to the fascia covering that muscle, the metacarpal bone, the capsule of the metacarpophalangeal articulation, or the first phalanx of the little finger. ❋ Unknown (1918)
Each slip gives off superficial fibers to the skin of the palm and finger, those to the palm joining the skin at the furrow corresponding to the metacarpophalangeal articulations, and those to the fingers passing into the skin at the transverse fold at the bases of the fingers. ❋ Unknown (1918)
Flexion of the metacarpophalangeal joints of the fingers is effected by the Flexores digitorum sublimis and profundus, Lumbricales, and Interossei, assisted in the case of the little finger by the Flexor digiti quinti brevis. ❋ Unknown (1918)
Running lateralward and downward, it is inserted by a thin, flat tendon into the radial side of the base of the first phalanx of the thumb and the capsule of the metacarpophalangeal articulation. ❋ Unknown (1918)
