Typical rib
Curved flat bone of the thorax
High-yield
The intercostal vein, artery, and nerve (VAN) run in the costal groove along the inferior rib border - the safe zone for chest drains is above a rib.
Overview
A curved flat bone of the thoracic cage; ribs 3-9 are typical, with a head, neck, tubercle, and body enclosing a costal groove for the neurovascular bundle.
Reference facts

- Flat
- Key landmarks
- Head; Neck; Tubercle; Angle; Body (shaft); Costal groove
- Articulations
- Thoracic vertebrae (costovertebral and costotransverse joints); Costal cartilage → sternum
Clinical correlation
Insert a chest tube just superior to a rib to avoid the intercostal neurovascular bundle in the costal groove.
