Sectorial angioarchitecture of the human tibia

Area of Science:

• Anatomy
• Vascular Surgery
• Orthopedics

Background:

• The periosteum, a vital membrane covering bones, relies on a specific blood supply for healing and integrity.
• Understanding the vascularization of the human tibia's periosteum is essential for surgical interventions and reconstructive procedures.

Purpose of the Study:

• To investigate and delineate the detailed blood supply system of the human tibia's periosteum.
• To identify specific arterial sources and their distribution patterns within different segments of the tibia.

Main Methods:

• Anatomical dissection of 12 lower extremities injected with a mass to visualize blood vessels.
• Division of the tibia into four distinct segments for detailed analysis: proximal and distal fifths, and proximal and distal diaphysis.

Main Results:

• The proximal tibia is supplied by recurrent tibial arteries and inferior genicular arteries.
• The tibial diaphysis receives blood from the anterior and posterior tibial arteries, with the distal diaphysis primarily supplied by the anterior tibial artery.
• The distal tibia exhibits variations, with the anterior tibial artery and fibular artery supplying the lateral aspect, and the fibular and posterior tibial arteries supplying the dorsal region.

Conclusions:

• A segmental vascular map of the tibial periosteum has been established.
• The findings provide critical anatomical data for orthopedic and vascular surgeons, aiding in procedures involving the tibia.
