Question

Sigmoid notch is present in?
A. Radius
B. Ulna
C. Humerus
D. femur

Answer 1

Hint: Constant repetitive volar disengagement of the distal radioulnar joint is an uncommon condition for which numerous usable methodologies have been depicted. We portray an instance of agonizing separation on supination.

Complete answer:
 The score is displayed when DRUJ shaking is available, regardless of whether the palm and ulnar tendon are intact, and has nothing to do with hyperplasia, sigmoid indentation or tracheal sigmoid sinus dorsal or volar marginal fissure, first consider based on DRUJ insecurity Score analysis of clinical history. Assess the stability of the anterior rotator, middle iron and supinator muscles to further doubt. Nevertheless, before reaching a conclusion, radiological confirmation must be performed with X-ray tomography (CT) images. This requires us to perform various anatomical and fluoroscopic examinations on 44 wrist specimens to observe pressure.

The ulna is one of the two bones of the forearm. Its concave surface connects with the small head of the humerus at the elbow joint. The ulna has a radial notch, forming a radioactive ulnar joint. The articular surface of the ulna is called the ulnar notch (sigmoid colon) of. It is located in the distal radius bone, narrow, concave, smooth and connected with the head of the ulna, forming the distal ulnar radial joint.

Hence, the correct answer is option (B)

Note: This study defined a view of the sigmoid colon incision of the distal radius bone. In particular, we tried an invalid hypothesis that there is no connection between the subchondral bone strip seen at the angle of the sigmoid notch in the distal range and the articular surface of the sigmoid notch.
