Ankle Joint

Ankle 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...

Area of Science:

Orthopedic Surgery
Sports Medicine
Biomechanics

Background:

Subtalar instability is a debated condition with unclear causes.
Overlapping symptoms with ankle instability lead to frequent misdiagnosis of subtalar issues.
Untreated subtalar instability can result in chronic ankle instability and treatment failure.

Purpose of the Study:

To provide a comprehensive overview of subtalar instability.
To elucidate the anatomy, biomechanics, and diagnostic methods for subtalar joint instability.
To review current treatment options and outcomes for subtalar instability.

Main Methods:

This is a narrative review synthesizing current knowledge.
Literature search on subtalar anatomy, biomechanics, diagnosis, and treatment.
Analysis of clinical and imaging diagnostic approaches.

Main Results:

Accurate diagnosis is essential for appropriate management of subtalar instability.
Understanding subtalar joint anatomy and biomechanics is fundamental.
Various conservative and surgical treatments exist for subtalar instability.

Conclusions:

Subtalar instability requires precise diagnosis for successful treatment.
Knowledge of subtalar joint structures and function is key.
Clinicians must be aware of diverse treatment options for informed decision-making.
