Summary
Rotational acetabular osteotomies carry risks of vascular injury. Anatomical measurements reveal females have shorter distances to key pelvic arteries, necessitating surgical caution.
Area of Science:
- Orthopedic Surgery
- Human Anatomy
- Vascular Anatomy
Background:
- Rotational acetabular osteotomies correct hip dysplasia in young adults.
- A significant risk during this procedure is intrapelvic vascular injury.
Purpose of the Study:
- To precisely define the spatial relationship between critical pelvic vasculature and bony landmarks.
- To identify potential anatomical variations that may influence surgical risk.
Main Methods:
- 34 cadaveric hemipelves were dissected to measure distances and directions.
- Measurements were taken from the anteroinferior iliac spine to the external iliac artery.
- Measurements were taken from the superior pubic ramus to the obturator artery.
Main Results:
- Females exhibited significantly shorter distances to both the external iliac artery and the obturator artery compared to males.
- The external iliac artery was positioned more ventrally and closer to the anteroinferior iliac spine on the right side.
- The obturator artery's entry portal was located more caudodorsally in females relative to the superior pubic ramus.
Conclusions:
- Anatomical variations in pelvic vasculature exist between sexes and sides.
- These findings highlight the need for heightened surgical awareness during rotational acetabular osteotomies to mitigate vascular injury risk.
