Braman describes the case of a man on whom several injuries were inflicted by a drunken companion. The first wound was slight; the second a deep flesh-wound over the trapezius muscle; the third extended from the right sterno-cleido-mastoid midway upward to the middle of the jaw and down to the rapine of the trachea. The external jugular, the external thyroid, and the facial arteries were severed.
Every vessel and nerve supplying the scalp was destroyed, and the pericranium was torn off in three places, one of the denuded spots measuring five by seven cm. and another five by six cm. The neck flap of the wound fell away from the muscular structures beneath it, exposing the trapezius muscle almost one-half the distance to the shoulder blade.
His limbs were not very large, nor his shoulders remarkably broad; but if you knew as much of the muscles as all persons who look at statues and pictures with a critical eye ought to have learned, if you knew the trapezius, lying diamond-shaped over the back and shoulders like a monk's cowl, or the deltoid, which caps the shoulder like an epaulette, or the triceps, which furnishes the calf of the upper arm, or the hard-knotted biceps, any of the great sculptural landmarks, in fact, you would have said there was a pretty show of them, beneath the white satiny skin of Mr.
Of the trunk: The pectoralis major, between the upper front part of the thorax and the shoulder; the trapezius, between the back of the shoulders and the spine; the rectus abdominis, passing over the abdomen from above downward; and the erector spinæ, found in the small of the back. Of the hips: The glutens maximus, fastened between the lower back part of the hips and the upper part of the femur.
This rotation is seen while the arm is being raised from the horizontal to the vertical position, and is effected by the cooperation of the trapezius with the serratus magnus muscles. The patella, or knee-pan, the two condyles of the tibia, the tubercle on the tibia for the attachment of the ligament of the patella, and the head of the fibula are the chief bony landmarks of the knee.
The following are the more important groups of glands, and the areas drained by them in the head and neck and in the extremities. The occipital gland, situated over the origin of the trapezius from the superior curved line, drains the top and back of the head; it is rarely infected. These three groups pour their lymph into the superficial cervical glands.
In those whose occupation entails carrying weights upon the shoulder it may be contused, and the resulting paralysis of the serratus is usually combined with paralysis of the lower part of the trapezius, the branches from the third and fourth cervical nerves which supply this muscle also being exposed to pressure as they pass across the root of the neck.
The muscles of expression soon share in the rigidity, and the face assumes a taut, mask-like aspect. The angles of the mouth may be retracted, producing a grinning expression known as the risus sardonicus. The next muscles to become stiff and painful are those of the neck, especially the sterno-mastoid and trapezius.
It affects almost exclusively the male sex, and usually begins in childhood or youth, sometimes after an injury, sometimes without apparent cause. The muscles of the back, especially the trapezius and latissimus, are the first to be affected, and the initial complaint is limitation of movement. [Illustration: FIG.
There is a case on record of a boy of fourteen who was shot in the right shoulder, the bullet entering through the right upper border of the trapezius, two inches from the acromion process. Those who examined him supposed the ball was lodged near the sternal end of the clavicle, four or five inches from where it entered. In about six weeks the boy was at his labors.
