Summary
This study details the anatomical measurements of the spring ligament complex (SLC) in cadaver feet. Understanding these dimensions, particularly of the superomedial (SML) and medioplantar oblique (MPO) ligaments, aids in precise surgical repair.
Area of Science:
- Anatomy
- Biomechanics
- Orthopedics
Background:
- The spring ligament complex (SLC) is crucial for medial longitudinal arch stability.
- Its integrity is vital, especially when posterior tibial tendon support is compromised.
Purpose of the Study:
- To precisely define the anatomical components and dimensions of the SLC.
- To clarify the distinct measurements of the superomedial (SML) and medioplantar oblique (MPO) ligaments.
Main Methods:
- Dissection of 30 adult cadaver feet.
- Measurements of ligamentous components and their borders were taken.
Main Results:
- Detailed average measurements for the superomedial ligament (SML), medioplantar oblique (MPO), and inferoplantar longitudinal (IPL) ligaments are provided.
- Specific dimensions at various borders and insertions (e.g., sustentaculum tali, navicular tuberosity) were recorded.
Conclusions:
- Distinguishing between SML and MPO components of the SLC can be challenging.
- This anatomical data can assist surgeons in performing more precise repairs of the spring ligament complex.

01:10Ankle Joint
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...
01:09Bones of the Upper Limb: Radius
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
