The lateral wrist radiograph is requested for myriad reasons including but not limited to trauma, suspected infective processes, injuries the distal radius and ulna, suspected arthropathy or even suspected foreign bodies. What is probably more useful is remembering that a lateral wrist radiograph will not rule out a forearm fracture given the. AP. the distal radial articular surface should cup the carpals. the articular surface should get progressively more distal towards the radial styloid. radial inclination angle should be 15-25°. lateral. the radial surface should be smooth. there should be a palmar tilt to the articular surface. volar tilt should be around 10-25°.
Wrist X Ray Anatomy The Anatomy Stories
Lateral view. Lateral views of the wrist are technically challenging to interpret due to overlying bony structures.. This view is obtained by positioning the patient as follows:. pronated wrist (ulnar side of the fifth digit facing down onto the X-ray plate); thumb facing upwards; Normal findings: The long axis of the radius, lunate, capitate and the third metacarpal bone should align. Citation, DOI, disclosures and article data. 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 radioulnar joint along.

Lateral radiograph of the right wrist The BMJ
A wrist X-ray (radiograph) is a test that produces an image of the inside of your wrist. The image displays the inner structure ( anatomy) of your wrist in black and white. A wrist X-ray shows your two forearm bones (radius and ulna) and eight wrist bones (carpal bones). Your carpal bones are aligned in two rows of four bones each at the base. How to interpret radiographs of the adult wrist—normal anatomy and distal radial fractures It is important for all newly qualified doctors to be confident in interpreting radiographs of the adult wrist, especially in the setting of acute trauma. The wrist is a common site of musculoskeletal injury,1 usually caused by falling on an outstretched hand.2 Every year around 282 000 falls occur in. On the AP, the articular surfaces of the carpal rows should form three smooth lines. Trace each of the arcs and ensure that there is a 1-2 mm joint space between each of the carpal bones. If there is widening of the space between the scaphoid and lunate, think scapholunate dissociation. The joint space between the distal carpal row and the. This lateral view of a normal wrist demonstrates the normal interface between the radius and lunate (red line) and the lunate and capitate (yellow line).
Wrist Radiographic Anatomy
The wrist is one of the most complex joints in the human body, allowing for stability during movement in all three cardinal planes of the human body. Categorically considered a hinge joint like the elbow, the wrist has additional planes of movement and rotation thanks to robust anatomy. Made up of eight carpal bones, the radius, ulna, and five metacarpals, the number of articulations and. no superimposition of triquetrum, lunate, or pisiform. Ulnar/radial deviation view. Positioning. patient. shoulder abducted 90° + elbow flexed 90° + forearm pronated + hand ulnarly vs. radially deviated. beam. aim at scaphoid. Indications. ulnar deviation = lateral wrist + scaphoid fracture.
Practical points. The aim of the horizontal beam lateral wrist is to avoid patient movement whilst achieving a diagnostic radiograph that rivals the quality of a walk in patient. This projection is paramount in the correct diagnosis of wrist fractures and consequently the patient's management. The tricky part of the projection is keeping the. This projection is an orthogonal view of the PA wrist and is used to diagnose fractures and localize foreign bodies in pediatric patients. It also provides information on the type of wrist fracture as an anteroposterior or posteroanterior dislocation can be diagnosed.

Pronator quadratus fascial plane . The pronator quadratus muscle extends across the volar surface of the ulna to insert on the volar and ulnar surfaces of the distal radius ( Figure 4-3 A ).The fascial surface of the muscle is outlined by a thin layer of fat that is visible on lateral radiographs of the wrist ( Figure 4-3 B ).Changes in the appearance of the pronator fascia plane are clues to. INTRODUCTION. When Wilhelm Conrad Rontgen created the radiograph of his wife Anna Bertha's hand in December 1895, the history of radiography and that of the hand and wrist imaging took its birth.[] Its first clinical application was also to detect a pathology of the wrist, that is, Colles' fracture a year later.[] From a 20-min exposure needed at that time for a radiograph to milliseconds.
