Deep Fascia
- Deep Fascia is a dense, inelastic fibrous membrane that separates the superficial fascia from the underlying structures. It is made up of regularly arranged collagen fibres.
- Deep Fascia sends septa between muscles from its deep aspect forming intermuscular septa.
“The Role Of Imaging In Studying Deep Fascia Layers”
- Deep Fascia ensheaths the muscles, vessels and nerves. The sheath around the muscles forms tunnels within which muscles can slide independent of the adjacent muscles.
- Deep Fascia forms thickened bands – the retinacula – at certain sites, such as wrist and ankle, which hold the tendons in place and prevent their bow stringing during the movements of the hand and feet at these sites.

Deep Fascia Clinical significance
The deep fascia forms fascial planes that are of special interest to surgeons because:
- They can operate along the fascial planes easily with minimal injury to adjoining structures.
- Deep fascia provide better understanding of the location and the routes of spread of pus as pus tracks along the fascial planes (i.e. paths of least resistance).

Modifications of Deep Fascia
- Intermuscular septa, in limbs to form fascial compartments
- Retinacula, i.e. extensor and flexor retinacula around wrist and ankle
- Fibrous flexor sheaths in digits of hand and feet
- Aponeurosis, i.e. palmar aponeurosis in palm and plantar aponeurosis in sole
- Ligaments to connect the bones at joints
- Fascial sheath around certain muscles
- Interosseous membranes in forearm and leg.
