The intercostal space (ICS) is the anatomic space between two ribs (Lat. costa). Since there are 12 ribs on each side, there are 11 intercostal spaces, each numbered for the rib superior to it.^[1]

Structures in intercostal space

several kinds of intercostal muscle
intercostal arteries and intercostal veins
intercostal lymph nodes
intercostal nerves

Order of components

Muscles

There are 3 muscular layers in each intercostal space, consisting of the external intercostal muscle, the internal intercostal muscle, and the thinner innermost intercostal muscle.^[2]^[3] These muscles help to move the ribs during breathing.^[4]

Neurovascular bundles

Neurovascular bundles are located between the internal intercostal muscle and the innermost intercostal muscle.^[3] The neurovascular bundle has a strict order of vein-artery-nerve (VAN), from top to bottom.^[2] This neurovascular bundle runs high in the intercostal space, and the smaller collateral neurovascular bundle runs just superior to the lower rib of the space (in the order NAV from superior to inferior). Invasive procedures such as thoracentesis are performed with oblique entry of the instrument, directly above the upper margin of the relevant rib, to avoid damaging the neurovascular bundles.^[2]

Nerves

In reference to the muscles of the thoracic wall, the intercostal nerves and vessels run posterior to the internal intercostal muscles: therefore, they are generally covered on the inside by the parietal pleura, except when they are covered by the innermost intercostal muscles, innermost intercostal membrane, subcostal muscles or the transversus thoracis muscle.

-Comprehensive insight in the anatomy of the intercostal spaces is mandatory for everyone who practices medicine. One particular concept is that the [[neurovascular bundle]] has a strict order: V-A-N, or vein-artery-nerve, from top to bottom (as illustrated). This neurovascular bundle runs high in the intercostal space, and the collateral neurovascular bundle runs just superior to the inferior rib of the space (in the order N-A-V from inferior to superior). Invasive procedures such as [[thoracentesis]] are thus performed with oblique entry of the instrument, directly above the upper margin of the relevant rib.
