What's the difference between ingrowth and tentorium?
Ingrowth
Definition:
(n.) A growth or development inward.
Example Sentences:
(1) Problems associated with cloth wear and the unexpectedly slow rate, in man, of tissue ingrowth into the fabric of the Braunwald-Cutter aortic valve prosthesis have been discouraging, although this prosthesis has been associated with a very low thromboembolic rate in patients receiving anticoagulant therapy.
(2) Simultaneously, bone ingrowth at the expense of the ceramic is observed.
(3) The subsequent resorption of the calcium sulfate leaves controlled porosity for bone ingrowth and attachment to the nonresorbable HA particulate.
(4) Bone ingrowth was greatest when hydroxylapatite was in direct apposition to bone.
(5) Direct measurement and stereological measurements of histological slides were able to give hard data for comparing ingrowth.
(6) A model based on a tissue ingrowth-bonded interface predicts uniform distribution of stresses around the implant through the cortical plates.
(7) Histologic examination revealed an ingrowth of loose connective tissue and also of normal-looking prostatic tissue in the sponge.
(8) Incorporation of porosity into the grafts, which is necessary for tissue ingrowth, is expected to lessen this difference.
(9) These cases show that rigid fixation with good bony ingrowth does not guarantee the clinical success of a porous-coated uncemented femoral stem.
(10) However, our data further suggest that enhanced ingrowth may not always lead to enhanced fixation.
(11) A new process of plasma-spraying hydroxyapatite--an entirely biocompatible, bioceramic material--onto porous, titanium alloy components promotes bone ingrowth into the components resulting in implant fixation, which is superior to current methods of cemented or cementless fixation.
(12) Studies on femurs retrieved at autopsy from patients who underwent cemented total hip arthroplasty two week sup to seventeen years earlier and were functioning well, have shown that the failure of cemented femoral components is initiated primarily by mechanical factors, consisting of debonding at the cement-prosthesis interface and fractures of the cement rather than lack of bone ingrowth or fibrous tissue formation at the interface.
(13) No bony ingrowth into the spinal canal was observed.
(14) The replamineform process is a unique means of studying surface healing and wall ingrowth of different biomaterials as microporous vascular prostheses in a controlled fashion.
(15) Implant stability resulting from bone remodelling and ingrowth occurred to varying degrees with all implants.
(16) Bone ingrowth was inhibited by 20 cycles of 0.5-mm movement applied during a 30-second period once daily.
(17) This investigation attempts to apply the concept of direct skeletal attachment via tissue ingrowth to the attachment of femoral head prostheses to the femur.
(18) In osteoconduction, the implant does not provide many viable cells but rather acts as a scaffolding for the ingrowth of new bone from the margins of the defect with the concurrent resorption of the implant; cortical bone grafts or banked bone segments are examples of this "creeping substitution."
(19) Fixation strength resulting from osseous ingrowth reached an average of 1380 N at a mean implant duration of 218 days.
(20) Our results support the view that autologous bone chips are effective in attaching cementless porous-coated total knee replacements to the human skeleton by bone ingrowth.
Tentorium
Definition:
(n.) A fold of the dura mater which separates the cerebellum from the cerebrum and often incloses a process or plate of the skull called the bony tentorium.
Example Sentences:
(1) The region of the tentorium and straight sinus can occasionally give rise to a vermiform appearance (the "AVM artifact").
(2) In children with tumors above the tentorium, only a reduction in the use of cerebral angiography and radioisotopic scanning was demonstrated.
(3) A zone of the tentorium cerebelli that is relatively poor in vessels and nerves and comparatively favourable for incision is established.
(4) A cavernous angioma of the tentorium cerebelli, first disclosed by perinatal serial ultrasonographic studies, was extirpated totally without remarkable neurological deficit in a neonate.
(5) The procedure involves section of the less dominent transverse sinus and the tentorium.
(6) This technique has also led to a better delimitation and sometimes a direct observation and spatial localization of some anatomical structures above and below the tentorium.
(7) A case of abnormal uptake of gallium in the tentorium cerebelli secondary to rheumatoid pachymeningitis is presented.
(8) Among them, 97 (23.4%) patients showed the appearance of TSAH in the Sylvian fissures, tentorium cerebelli, cortical sulci, basal cisterns and interhemispheric fissures.
(9) In those cases without spina bifida, ventricular enlargement should occur early and be greatest in the forebrain, driving the tentorium and posterior fossa structures downward.
(10) The technique is also widely applicable for closing (or suturing) the dura following any procedure through a small opening, such as the dural tears occasionally encountered during lumbar or cervical discectomy, or tacking the tentorium during a craniotomy.
(11) The tentorial sinuses were classified into four groups: Group I, in which the sinus received venous blood from the cerebral hemisphere; Group II, in which the sinus drains the cerebellum; Groups III, in which the sinus originates in the tentorium itself; and Group IV, in which the sinus originates from a vein bridging to the tentorial free edge.
(12) In the preliminary study, a dry human skull with an artificial "tentorium" made of thick paper was prepared to decide the fundamental plane for volume measurement by CT scan.
(13) The configuration of Model III is the same as Model II but more detailed anatomical features of the head interior were added, such as, cerebral spinal fluid (CSF); falx cerebri, dura, and tentorium.
(14) These two disseminated tumors had attachments to the inferior surface of the cerebellar tentorium and the dura mater of the parietal convexity, respectively, and they were fed by external carotid artery branches, like meningiomas.
(15) Incision of the tentorium prior to removal of a tumor when it invades the incisural hiatus may have merit.
(16) Three patients with diffuse idiopathic cranial pachymeningitis with predominant involvement of the tentorium and falx are reported.
(17) Even more so are multicentric gliomas lying both above and below the tentorium (16 cases to date, as far we know).
(18) IIIA seems to be generated from the medial lemniscus at the level of osseous cerebellar tentorium.
(19) After this test became available there was a significant (P less than .05) reduction in the utilization of cerebral angiography, echoencephalography, electroencephalography, and ventriculography in children with tumors below the tentorium.
(20) A roentgenological investigation of 38 patients with meningiomas of the tentorium cerebelli of the supra-subtentorial growth revealed signs of hypertension in 31 of them.
