A Review on Reading Wrist X-rays — The Sports Medicine Review, A normal lateral radiograph of the wrist shows slight volar tilt of the radius (Jack Porrino, 2014). In order to assess for pathologic tilt, a vertical line is drawn through the radius and then a perpendicular line is drawn through the lunate facet (Jack Porrino, 2014).
The wrist series is comprised of a posteroanterior, oblique, and lateral projection. The series examines the carpal bones that are consisting of the scaphoid, lunate, triquetrum, pisiform, trapezium, trapezoid, capitate and hamate. It also examines the radiocarpal and distal radiocarpal joint along with the.
We observe that the lateral view at 7° is better to show the screws on the lunate facet of the radius. The lateral view at 22° is better to show the facet of the radius with the scaphoid. Finally, the anteroposterior projection at 11° allows us to see the radio carpal joint with lower image overlay.
lateral wrist X – ray gives a very good outline of the lunate facet and makes measurement under fluoroscopy easy to assess proper fracture reduction. The volar tilt angle was adequately reduced in both groups, possibly because that is one of the landmarks ac.
The posteroanterior (PA) projection (Fig. 5) is obtained with the arm abducted 90° from the trunk and the forearm ?exed at 90° to the arm.6With the forearm in this pronated posi- tion,theulnarstyloidisseeninpro?le.Whenviewsaretaken insupination,theulnarstyloidoverlapsthecentralportionof the distal ulna.
This means that the wrist, elbow and shoulder are all in the transverse plane, perpendicular to the x-ray beam. Only in this position, the radius and the ulna are parallel. Lowering the arm makes the radius cross the ulna and become relatively shorter resulting in improper measurement of the length of the radius.
review of radiographs of the wrist and hand. Evaluation of the Hand Standard hand radiographic projections include the posterior-anterior (PA) view, lateral view and ob, lique view In the P. A view the hand is , placed palm down on the cassette with the X – ray beam angled at.
The carpal facet horizon also is used to identify whether a particular fragment on the PA view involves the dorsal rim or volar rim. In fractures that are volarly displaced in which there is volar tilt of the articular surface on the lateral x-ray, the carpal facet horizon identifies the volar rim of the lunate facet. In fractures that are dorsally displaced in which there is dorsal tilt of the articular surface on the lateral x-ray, the …
