|September 1, 1977
Summary
The study details the arterial supply of the coxal bone, revealing that nutritive and periosteal blood vessels originate from the internal and external iliac arteries. Key findings highlight the ilium
Area of Science:
- Anatomy
- Vascular Biology
- Surgical Anatomy
Context:
- The coxal bone, or hip bone, is a complex structure crucial for locomotion and pelvic support.
- Understanding its arterial supply is vital for orthopedic surgery, trauma care, and reconstructive procedures.
- Previous studies have provided general outlines, but detailed microangiographic analysis offers new insights.
Purpose:
- To meticulously map the arterial vascularization of the coxal bone using microangiographic techniques.
- To identify the specific sources and pathways of nutritive and periosteal blood supply to the ilium, ischium, and pubis.
- To elucidate the vascular architecture and anastomoses within the coxal bone, particularly around the acetabulum.
Summary:
- Microangiographic study reveals that nutritive and periosteal blood vessels supplying the coxal bone arise from the internal (Iliaca interna) and external (Iliaca externa) iliac arteries.
- The ilium receives its primary nutritive supply from the Ilio-lumbalis artery, supplemented by periosteal vascularization.
- The ischium and pubis are primarily supplied by periosteal blood vessels, with all vascular elements converging towards the acetabulum, forming significant anastomoses.
Impact:
- Provides a detailed anatomical map crucial for surgeons performing procedures on the hip and pelvis.
- Enhances understanding of coxal bone healing and potential complications related to vascular compromise.
- Forms a basis for further research into pelvic vascular diseases and reconstructive techniques.
