(1) A delayed rupture is most probably caused by an avascular necrosis secondary to traumatic disruption of the mesotendon.
(2) The mesotendon approached the tendon from the medial aspect and was fenestrated in the dog (here only in the proximal segment), pig, sheep, and goat, but in the cat and ox the fenestration was inconstant.
(3) In the synovial sheath the arteries reach the tendon through the mesotendon.
(4) The results indicate that diffusion from the synovium is a more significant nutrient pathway than vascular perfusion from either the mesotendon or the longitudinal intratendinous vascular network.
(5) In the mesotendon and bursal extremities, where the lining is subjected to a positive degree of movement, the cellular layer was areolar in type with well established folds populated by abundant cells oval to round in shape.
Vinculum
Definition:
(n.) A bond of union; a tie.
(n.) A straight, horizontal mark placed over two or more members of a compound quantity, which are to be subjected to the same operation, as in the expression x2 + y2 - x + y.
(n.) A band or bundle of fibers; a fraenum.
(n.) A commissure uniting the two main tendons in the foot of certain birds.
Example Sentences:
(1) Specialized areas observed in the normal chick (synovial cavity, fibrocartilaginous area, and elastic vinculum) failed to form, as a result of the paralysis of the digit.
(2) Experiments on mongrel rats have revealed that ulceration of mucous membrane of the stomach achieved by vinculum of pylorus is formed only in 47% of animals.
(3) Cell density and DNA analyses indicated a slightly higher cellularity for fibrocartilaginous areas and the region of vinculum insertion.
(4) In group 1, shortening and physical changes were limited to the portion distal to the anchoring of the vinculum and the physical properties were well preserved and remained almost normal.
(5) We conclude that this branch supplies the nerve fibres found within the vinculum.
(6) The operative findings suggest a rare instance of detachment or rupture of the vinculum of the intact superficial flexor tendon.
(7) Two cases are described with full flexion of the proximal interphalangeal joint produced by an intact short vinculum after complete laceration of both superficialis and profundus tendons.
(8) The vinculum breve of the flexor digitorum profundus tendon was found to apply traction to the volar plate on flexion of the distal interphanageal joint.
(9) Although the precise reason for rupture is not known we have speculated that the anomalous superficialis may have given rise to a deficient vinculum longus to the profundus predisposing it to failure.
(10) Then, we arrive at universal situations about the roles in the psychotic's family: fixation and immobility, stereotypy and aupplementarity, double vinculum situation, the family gives up modifying the structure and the patient who assumes the family pathology is almost permanently disqualified.
(11) Distally, vessels arose from the vinculum breve, supplying the terminal twenty millimeters of tendon substance.
(12) Diffusion is the primary nutrient pathway to the flexor tendon in this area, because removing its major vascular attachment (i.e., the vinculum longum) did not effect proline uptake.
(13) The tendons were either: normal and uninjured, lacerated and repaired, or uninjured except for vinculum longum ligation.
(14) Vascular loop patterns, similar to those seen in synovial lining of joints or on either side of the growth plate of growing bone, were found on the surface of the tendons in the area of mesotenon reflection, the osseotendinous junctions, where the vinculum joined the tendon, and in various areas of the tendon sheath.
(15) The present study examines several biochemical parameters of avian flexor tendon repair, during a six-week period, in the presence of an intact vinculum longum and with the vinculum longum ligated.
(16) The dorsal aspect of the distal segment was further characterized by a cell rich area related to the entrance of the vinculum longum.
(17) At the insertion of the tendon there was regularly a very well developed vinculum brevis, often extending proximally to the middle of the base phalanx of the thumb.
(18) The importance of proximal retraction, the delay before diagnosis and the involvement of the long vinculum provide the basis for a classification into three types.
