Ankle Joint01:10

Ankle Joint

2.8K
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...

Bones of the Lower Limb: Tibia and Fibula

8.7K
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...

Summary

Ankle joint morphometrics, including fibula distal length and specific angles, may indicate a risk for osteochondral lesions (OCL). These measurements were significantly different in patients with OCL compared to controls.

Area of Science:

  • Orthopedic Surgery
  • Radiology
  • Biomedical Engineering

Background:

  • Osteochondral lesions (OCL) of the ankle are a common cause of joint pain and dysfunction.
  • Understanding the anatomical factors contributing to OCL is crucial for diagnosis and treatment.

Purpose of the Study:

  • To investigate the relationship between ankle joint morphometric parameters and the presence of osteochondral lesions.
  • To identify potential morphometric risk factors for talus osteochondral lesions.

Main Methods:

  • Retrospective analysis of magnetic resonance images (MRIs) from 127 patients with OCL and 124 controls.
  • Morphometric measurements of the ankle joint, including fibula distal length (FDL), alpha (α) angle, and delta (δ) angle, were performed on coronal and sagittal MRIs.

Main Results:

  • Fibula distal length (FDL) was significantly different between OCL and control groups in both males and females (P=0.04, P=0.01).
  • Alpha (α) angle and delta (δ) angle measurements showed significant differences between groups in males (P=0.02, P=0.04).

Conclusions:

  • Elevated FDL, alpha (α) angle, and delta (δ) angle measurements suggest these morphometric parameters may be potential risk factors for talus osteochondral lesions.
  • These findings highlight the importance of ankle joint morphometry in the development of OCL.
