Determination of correct implant size in radial head arthroplasty to avoid overlengthening. J Bone Joint Surg [Am] 2009;91- A:1738-46.Athwal GS, Frank SG, Grewal R, Faber KJ, Johnson J, King GJ (2010) Determination of correct implant size in radial head arthroplasty to avoid over...
Open lag screw fixation could result in either poor compression or joint arthrosis as the head of the screw would reside on the articular surface and therefore cause secondary joint injury.6 Herbert designed a single piece non-cannulated HCS in order to provide internal compression and stability ...
The centre of rotation for flexion/extension and radial/ulnar deviation is located in the head of the capitate [8]. Most rotation occurs between the distal radius and ulna (pronation and supination, Fig. 1), although subtle degrees of rotation take place between the carpal bones and the ...

The base information of the concrete design strength index, section size and upstream head is shown in Table 1. Table 1. Table of foundation information of corbel beam. 2.2. Concrete Quality Inspection of the Corbel Beam Structure To accurately analyze the real working state and stress distribut...
In the hand, the attaching tendinous fibers lie deep to the oblique head of adductor pollicis muscle. In relation to neurovascular structures, the proximal part of the muscle covers the median nerve, prior to it passing beneath the flexor digitorum superficialis muscle. Just proximally to the ...
When checking, consideration should also be paid to the rod end head (housing) material which differs depending on design and size (automatic or forged steel, cast iron with spheroidal graphite). Structure Rod end bearing Type Radial spherical plain bearings Seals Type ...
the clamp fingers 58 can comprise a variety shapes which allow resilient retention adjacent the log 28. For example, the clamp fingers 58 could be resiliently retained in a mounting which reversed the orientation of a T, wherein the head of the contacted log 28 and the leg was resiliently...
12 which operate on a common extrusion head 13. By means of the two extruders 11, 12 the mixtures forming the base layer or ply 1 and the cap layer or ply 2 are simultaneously extruded. The extrusion head 13 is provided with inserts 21 which can be exchanged, if desired. A preforming...
definite number for the optimum clearance. Sixsmith[54]determined it to less than 0.3mm to prevent excessive backflow. Through comparison of experimental and theoretical results of different axial clearance values (0.01–0.08mm) Badami[32]found that 0.01mm provided a higher head and better ...
