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...

Summary
This summary is machine-generated.

Rotational ankle instability (RAI) can be diagnosed using a noninvasive postural control assessment measuring "coronal instability." This method shows high accuracy, potentially outperforming traditional imaging for chronic ankle instability (CAI).

Area of Science:

  • Orthopedics and Sports Medicine
  • Biomechanics
  • Diagnostic Imaging

Background:

  • Deltoid ligament (DL) injuries are increasingly linked to chronic ankle instability (CAI) and rotational ankle instability (RAI).
  • Current methods for assessing RAI lack insight into ligamentous damage and rotational instability.
  • Need for improved diagnostic tools for RAI in CAI patients.

Purpose of the Study:

  • To evaluate characteristic rotational instability in RAI.
  • To identify postural control parameters that best represent RAI.
  • To establish quantitative diagnostic thresholds for RAI using postural control.

Main Methods:

  • 32 patients with CAI underwent postural control assessment (center of pressure analysis and sensory organization test).
  • Talar tilt angle and medial clear space measured via radiography and MRI.
  • Arthroscopic findings confirmed diagnoses; Receiver operating characteristic (ROC) curves analyzed diagnostic utility.

Main Results:

  • RAI showed an elevated ratio of coronal-plane to sagittal-plane sway amplitude ('coronal instability').
  • Coronal instability demonstrated high diagnostic performance (AUC=0.95), surpassing imaging techniques (AUC=0.567-0.844).
  • Optimal cutoff (0.81) yielded 83.33% sensitivity and 100% specificity for RAI detection.

Conclusions:

  • Noninvasive postural control assessment of coronal instability is highly sensitive and specific for diagnosing RAI.
  • This method provides a valuable clinical tool for RAI identification.
  • Postural control assessment may complement or exceed traditional imaging in diagnosing RAI.
