Typical ribs
Ribs three to nine are the ‘typical’ ribs and the major landmarks are the head, neck, tubercle and body.
Atypical ribs
The first, second and tenth to twelfth ribs are known as atypical and as such will be considered individually.
Ligaments
The main ligamentous attachment to the ribs is the costotransverse ligament, this is a fairly complex ligament which is made up of three parts. The first part is known as ‘The’ costotransverse ligament and it fills the gap between the rib and the corresponding transverse process.
Muscles attachments
There are eleven pairs of external intercostal muscles and these are the most superficial in the area. They extend from the lateral border of the costal grooves to the superior margins of the ribs below.
Clinical notes
This is a commonly performed procedure and is necessary in cases of pneumothorax, pleural effusion, empyema and postoperatively following thoracic surgery. It is particularly important to place the tube in line with the superior border of the rib.
