Marking joint lines Flashcards
How to mark the knee joint line:
this can be felt below the anterior margins of each femoral condyle and above the anterior margins of each tibial condyle.
The joint line can be felt anteriorly, medially and laterally
How to mark the Hip joint line:
the joint centre lies in a horizontal plane passing through the top of the greater trochanter.
The joint centre lies 1 cm below the middle third of the inguinal ligament (this goes from the ASIS to the pubic tubercle).
How to mark the ankle joint line:
lies in a horizontal line 1 cm above the tip of the medial malleolus and 2 cm above the tip of the lateral malleolus – and palpated on the dorsal surface.
Palpate the inner border of the medial malleolus, lower end of tibia and medial edge of lateral malleolus
How to mark the shoulder joint line:
the midpoint of the joint is approximately 1 cm lateral to the coracoid process. A vertical line, slightly concave laterally, through this point identifies the joint line
How to mark the elbow joint line:
drawing a line 1 cm below the lateral epicondyle and 2 cm below the medial epicondyle.
It can also be felt posteriorly between the head of the radius and the capitulum.
How to mark the superior radioulnar joint line:
can be palpated posteriorly. Identify the head of the radius. A vertical groove can be felt medially between the radius and ulna
How to mark the inferior radioulnar joint line:
a vertical line can be felt on the posterior aspect of the wrist joint between the radius and the ulna
How to mark the wrist joint line:
line drawn between the 2 styloid processes (radial and ulnar) – slightly concave.
how to mark the acromioclavicular joint line:
immediately lateral to the anterior concavity at the lateral one-third of the clavicle, approximately 1.5 cm medial to the lateral border of the acromion process. It can be marked from above by drawing a line in an antero-posterior direction
