Numerical Lubrication Simulation of Metal-on-Metal Hip Joints: Ball-in-Socket Model and Ball-on-Plane Model Long-term successful function of artificial hip joint replacements strongly depends on the design parameters of the bearing such as the diameters of femora... WZ Wang,FC Wang,ZM Jin,.....
The joint between the trapezium and the first metacarpal is anatomically like a saddle. In function, however, it is used like a ball and socket joint with the following possible movements: 1. Flexion - extension, 2. abduction - adduction... W Thomas,W Thomas - 《Handchirurgie》 被引量: ...
1. a social function for dancing, esp one that is lavish or formal 2. informal a very enjoyable time (esp in the phrase have a ball) [C17: from French bal (n), from Old French baller (vb), from Late Latin ballāre to dance, from Greek ballizein] Ball (bɔːl) n (Biograp...
CONCENTRIC INTERIOR INSERT BALL AND DUAL SOCKET JOINT A constrained spinal implant is inserted between adjacent vertebrae to function as an disk prosthesis. The prosthesis has two plates fastened to adjacent vertebrae facing each other. The facing sides of the plates each have a depending s... R...

The treatment is associated with costs and the recovery may take up to 1 year after surgery depending on the procedure. No randomized controlled trials have been conducted comparing ball and socket TMC prosthesis to trapeziectomy with ligament reconstruction. Methods A randomized, blinded, parallel-...
The experimental data are fed directly into the optimizer allowing training to be performed according to a predefined loss function. To predict sliding friction and wear at mixed lubrication conditions, in this study a specific ANN structure was so designed that deep learning algorithms and data-...
Function:Ball joints are usually ball and socket design, lubricated with grease and covered with dust boots. Most of the ball joints are now sealed to prevent dust, grit and other impurities from damaging the joint and to prevent maintenance. How do you know ...
A number of methods are known for retaining the ball or part-spherical femoral head in the bearing surface of the acetabulum or socket. In the most common method, referred to herein as “semi-constrained” construction, the patient's own anatomy, i.e., his muscles, tendons and ligaments, ...
Improvement in ball-and-socket joints Reduced energy consumption is critical in industrial applications. In this manuscript, we report our findings on cutting condition improvement for 5-axis m... ET Starr - US 被引量: 30发表: 0年 Surface finish improvement in ball nose end milling by optimizi...
