Pertinent Blood Supply for Hallux Valgus Surgery

- Discussion:
    - blood supply to 1st metatarsal head is both extraosseous & intraosseous;
    - extra-osseous supply:
          - enters metatarsal on its lateral and dorsolateral surface 2 cm proximal to the joint;
          - extra-osseous branches also enter lateral capsule;
          - significant stripping of both dorsal & lateral aspects of distal metatarsal may disrupt the extraosseous supply;
    - intraosseous supply:
          - provides circulation through both diaphysis & metaphysis of the metatarsal
