Of the flexor tendons, the perforans is the one commonly attacked, by reason, of course, of its more superficial position. ❋ Harry Caulton Reeks (N/A)
The flexor perforans tendon showed inflammatory softening, and was very nearly ruptured through at the level of the navicular bone. ❋ Harry Caulton Reeks (N/A)
On the anterior surface of the perforans fibres of the tendon are seen to be torn away from their abnormal adhesion with the navicular bone, while others are seen to be still attached thereto. ❋ Harry Caulton Reeks (N/A)
The metacarpo-phalangeal sheath and the ring of the perforatus laid open posteriorly, and the cut edges reflected to show the passage of the perforans. ❋ Harry Caulton Reeks (N/A)
The circumstances we have mentioned before -- pressure of the exudate upon it in front and tension of the perforans on it behind -- have caused it to assume ❋ Harry Caulton Reeks (N/A)
The metacarpo-phalangeal sheath and the ring of the perforatus laid open posteriorly, and the cut edges reflected; the flexor perforans cut through at about the region of the sesamoids, and its inferior portion deflected. ❋ Harry Caulton Reeks (N/A)
-- The terminal portions of the extensor pedis and the flexor perforans. ❋ Harry Caulton Reeks (N/A)
-- In common with the perforans, this muscle arises from the inner condyloid ridge of the humerus. ❋ Harry Caulton Reeks (N/A)
In the articulation with which we are dealing, however, these last two symptoms are not easily detected, for the surrounding structures -- namely, the lateral and other ligaments of the joint, the extensor pedis tendon in front, and the perforans behind, together with the dense and comparatively unyielding nature of the skin of the parts -- are such as to prevent distension and fluctuation becoming marked to a visible extent. ❋ Harry Caulton Reeks (N/A)
In the recent state it is covered with fibro-cartilage for the passage of the flexor perforans. ❋ Harry Caulton Reeks (N/A)
In this category we may place injuries to the terminal portion of the perforans, puncture of the navicular bursa, fracture of the navicular bone and penetration of the pedal articulation, and splintering of the os pedis. ❋ Harry Caulton Reeks (N/A)
Secondly, the manner in which the animal distributes his weight -- namely, upon the heels -- is calculated to aid in the bone's backward movement, for with his feet in this position tension upon the extensor pedis is relaxed, while that upon the flexor perforans is greatly increased. ❋ Harry Caulton Reeks (N/A)
Seeing that with every movement of the foot the perforans tendon is called upon to glide over this surface, it is clear that a secondary effect must be that of inducing erosion and destruction of the tendon. ❋ Harry Caulton Reeks (N/A)
Whichever may have been the case, we have in the hollow of the heel one or more fistulous openings, or an opening we have made ourselves, leading down to a necrosed portion of the terminal expansion of the perforans. ❋ Harry Caulton Reeks (N/A)
We must admit, however, that the cure of the lesion is generally at the expense of slight lameness, due, in all probability, to inflammatory tissue adhesions between the flexor perforans and the perforatus, and to a partial destruction of the synovial membrane of the sheath. ❋ Harry Caulton Reeks (N/A)
Tendon the extensor pedis the flexor pedis perforans the flexor pedis perforatus ❋ Harry Caulton Reeks (N/A)
At times, however, especially when its aponeurotic expansion is diseased, the necrosis of the perforans spreads until the aponeurosis is eaten through and the phalangeal sheath penetrated. ❋ Harry Caulton Reeks (N/A)
The flexors were apparently all right, and the bending back seemed to be due to contraction of the ligaments of the joint and the sheath of the perforans. ❋ Harry Caulton Reeks (N/A)
In this manner the pressure of the perforans tendon upon the bursa is greatly increased, and the animal is caused to show symptoms of distress. ❋ Harry Caulton Reeks (N/A)
The posterior surface of the complementary cartilage forms a gliding surface for the passage of the perforans. ❋ Harry Caulton Reeks (N/A)
