Summary
The acetabulum pedis (AP), a foot joint socket, has five walls. Variations in its calcaneal facets and ligaments can alter foot shape.
Area of Science:
- Anatomy
- Biomechanics
- Podiatry
Background:
- The talocalcaneonavicular joint is a crucial component of foot structure and function.
- Understanding the acetabulum pedis (AP) architecture is essential for diagnosing and treating foot deformities.
Purpose of the Study:
- To provide a detailed architectural description of the acetabulum pedis (AP).
- To investigate how variations in AP structure influence foot shape.
Main Methods:
- Architectural analysis of the acetabulum pedis (AP) based on observations of 72 feet from necropsies of stillborns or deceased newborns.
- Identification and description of the five walls of the AP: superior, inferior, anterior, medial, and lateral.
Main Results:
- The acetabulum pedis (AP) is characterized by five distinct walls.
- Variations in the tridimensional positioning of the calcaneus's anterior and middle articular facets significantly affect the acetabular floor area.
- Alterations in ligament positioning within the acetabular floor and medial wall also modify these areas.
Conclusions:
- The acetabulum pedis (AP) possesses a complex five-walled structure.
- Morphological variations in the calcaneus and associated ligaments directly impact the acetabular floor and medial wall, leading to changes in overall foot shape.
