A New Design of the Tooth Profile for Single Screw Compressors [PDF]

, 2012
The wear of star wheel teeth is an importance issue in the single screw compressor. In order to enhance the wearresistance of star wheel teeth, some new profiles of the meshing pair were proposed to replace the currently used straight line envelope ...

Avoiding articular breakthrough in screw fixation of radial head fractures

JSES International, 2022
Background: The radial head is anatomically complex, making fracture fixation challenging because of the difficult visualization of the articular surface. As a result, screw penetration into the radiocapitellar joint can often occur.

Biomechanical analysis of the computer-assisted internal fixation of a femoral neck fracture

Genes and Diseases, 2020
The number and spatial configuration of the screws will affect the stability and prognosis of the fractures. In our study, we assessed the biomechanical effects of the double-head cannulated compression screw (DhCCS) and ordinary cannulated compression ...

Bicondylar Hoffa Fracture: A Rare Variant of Intra-Articular Fracture

Journal of Bone and Joint Diseases, 2023
A Shear fracture of posterior aspect of femoral condyles in coronal plane is known as Hoffa fracture. This fracture pattern, originally described by Hoffa, is an intra-articular fracture and radiologically and clinically silent most of the times and thus
