What's the difference between triquetra and triquetral?
Triquetra
Definition:
(pl. ) of Triquetrum
Example Sentences:
(1) Within each P, V, and O there is also a triquetra which rotates and which will determine how that individual behaves in the next instance.
(2) It appears they form a triangle or triquetra which rotates with time and circumstance.
(3) A triquetra of these three rotates with time and circumstance.
Triquetral
Definition:
(a.) Triquetrous.
Example Sentences:
(1) Midcarpal instability occurs at the triquetral-hamate joint and is characterized by a dynamic subluxation of the joint.
(2) Capitate-hamate-lunate-triquetral fusions reduced compressive strains by 28.5% and tensile strains by 26.3%.
(3) Disruption of the LT ligament is frequently associated with pathology in the ulnar carpal area and may progress to triquetral instability, VISI, and finally, degenerative arthritic changes on the ulnar side of the carpus.
(4) Using the technique for digital subtraction wrist arthrography outlined in this paper, the classic scapho-lunate and lunate-triquetral perforations were delineated.
(5) The contribution of the scapho-lunate and luno-triquetral joints to global wrist motion was studied in 11 fresh-frozen cadaver specimens.
(6) to occur the lunate triquetral interosseous ligament must be disrupted.
(7) A case of hamate dislocation associated with triquetral fracture is presented.
(8) Luno-triquetral instability dogs not appear to be as rare as one is lead to believe.
(9) A rare case of trans-radial styloid, trans-scaphoid, trans-triquetral perilunate dislocation is described.
(10) The authors are reporting a retrospective series of 24 patients which fall into two separate groups: 14 isolated luno-triquetral lesions, 10 associated with a generalized involvement of the proximal carpal row, either as a result of peri lunate dislocation or combined scapho-lunate and luno-triquetral instability without anterior subluxation.
(11) Extra-articular radius fractures were associated with an intracarpal ligamentous tear in 25% and always a luno-triquetral lesion type.
(12) Significant variations in size of triquetral attachment and thickness and consistency of the ulnocarpal ligamentous complex (UCLC) were observed.
(13) We suggest a limited wrist arthrodesis as definitive treatment for symptomatic congenitally incomplete separation of the triquetral-lunate joint, with possible application in incomplete separation of the other intercarpal joints.
(14) Initial radiographs of the patient showed only fractures in the bilateral proximal radius and the right triquetral bone.
(15) Triquetral fractures are relatively uncommon, but when present, often go undiagnosed or are misdiagnosed as lunate fractures.
(16) It is anchored by strong ligaments to the scaphoid on one side and the triquetrum on the other, thus forming a 3-bone intercalary system, which is in turn guided by the palmar distal V-ligament and the dorsal radio-triquetral ligament.
(17) The main ligaments involved in this instability appeared to be the ulnar half of the volar arcuate ligament and the luno-triquetral ligament as division of these ligaments, particularly under axial loads, produced the most significant change in lunate rotation (p less than 0.05).
(18) Restoration of the normal scapholunate interval was not possible until the triquetral fracture was reduced.
(19) In stage I, a complete sectioning of both the dorsal and palmar luno-triquetral ligaments and the interosseous membrane was done.
(20) Laxity of the capitotriquetral ligament results in failure of the triquetral-hamate joint to produce a dorsiflexion moment, and the unbalanced volar flexion moment generated by the scaphoid produces volar intercalated segment instability (VISI).
