The vincula; with particular reference to their vessels and nerves

Area of Science:

• Anatomy
• Vascular Biology
• Hand Surgery

Background:

• The vincula are crucial for flexor tendon nutrition.
• Understanding their vascular and nerve supply is vital for hand function and surgical outcomes.

Purpose of the Study:

• To anatomically detail the blood vessels and nerves within the vincula of the human hand.
• To elucidate the segmental blood supply to flexor tendons via the vincula.

Main Methods:

• Anatomical dissection of human hand specimens.
• Serial histological sectioning for detailed tissue analysis.
• Angiography to visualize the vascular network.

Main Results:

• Identified constant arterial branches from digital vessels supplying the flexor tendons through the vincula.
• Demonstrated accompanying nerves extending into the flexor tendons.
• Confirmed communication between interosseous and tendon circulation.

Conclusions:

• The vincula provide a defined segmental blood supply to flexor tendons.
• These anatomical findings have significant clinical implications for tendon surgery and injury management.
