The fixation of maxillofacial fractures is an important clinical procedure, which may be achieved by the attachment of plates across the fracture. The stability of the fracture will depend on the stiffness of the fracture fixation plates and the security of the fixation screws to the thin maxillofa...
1.Experimental study of screw pull-out strength of posterior cervical oligo-segmental fixtion for treament of Hangman's fracture;Hangman骨折后路短节段内固定术固定螺钉拔出力研究 2.Relationship of Vertebral Body Bone Mineral Density with Insertional Torque and Pull-out Strengths of Pedicle Screws and ...
To determine the pullout strength of adaption screws in laryngeal cartilage and its relationship to drill hole and screw diameter. Screw pullout strength in human cadaver thyroid cartilage was measured using a load cell. Screw sizes of 1.3, 1.5, and 2.0 mm were tested using drill hole diameters...
5) Generally, larger standard deviations were found for the screw back-out cases, implying that the results of full insertion cases are more repeatable than those of the back-out cases. Conclusions:Solid screws with retrograde cement pre-filling offer improved initial fixation strength when compared...
1.Objective To investigate the influence of screw length(18,20,and 24 mm) on the axial pullout strength of full thread cancellous screws.目的探讨螺钉长度对全螺纹松质骨螺钉轴向最大拔出强度(Axialmaximumpulloutstrength)的影响。 英文短句/例句 1.Pull-out strength of posterior lower cervical screws ...
Objective To evaluate the pull-out strength of posterior lower cervical screws inserted by three fixation Techniques.Methods Six fresh cervical spine samples(C3～C7) were implanted with screws using lateral mass screw Roy-camille technique,pedicle screw technique and transarticular screw technique,respecti...
While the biomechanical properties of pedicle screws have proven to be superior in the lumbar spine, little is known concerning pullout strength of pedicle screws in comparison to hooks in the thoracic spine. In vitro biomechanical pullout testing was performed to evaluate the pullout strength of ...
The pullout strengths of large diameter cannulated and noncannulated cancellous screws were tested in a synthetic polyurethane foam. The foam was fabricated to have mechanical properties equivalent to human cancellous bone and was characterized by compression testing before screw pullout. Long and short...
