Ankle Joint

3.1K
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

Postural stability deficits are a risk factor for ankle sprains, but results vary. Measuring center-of-gravity sway and using the Star Excursion Balance Test (SEBT) show promise for identifying at-risk individuals.

Area of Science:

  • Sports Medicine
  • Biomechanics
  • Injury Prevention

Background:

  • Ankle sprains are common injuries, particularly in athletes.
  • Postural stability is crucial for preventing lower limb injuries.
  • Identifying risk factors for ankle sprains is essential for effective prevention strategies.

Purpose of the Study:

  • To systematically review evidence on postural stability as a risk factor for ankle sprains.
  • To identify the most effective methods for evaluating postural stability to predict ankle sprains.
  • To explore confounding factors influencing postural stability and ankle sprain risk.

Main Methods:

  • Systematic electronic search of MEDLINE, EMBASE, and CINAHL databases.
  • Inclusion of prospective studies evaluating postural stability as a risk factor for ankle sprains.
  • PRISMA checklist guided reporting and data abstraction; methodological quality was assessed.

Main Results:

  • Fifteen studies (2860 individuals) were included; injury incidence ranged from 10-34%.
  • Postural stability deficits were identified as a risk factor in 9 studies (OR=1.22-10.2), particularly with the Star Excursion Balance Test (SEBT).
  • Center-of-gravity sway measurements detected poorer stability in injured athletes, while examiner evaluations were less consistent. History of ankle sprain confounded results.

Conclusions:

  • The role of postural stability in ankle sprain risk is not definitively established due to study heterogeneity.
  • Center-of-gravity sway measurement shows potential for risk identification, but standardized protocols are needed.
  • The SEBT is a promising tool requiring further investigation; ankle sprain history is a significant confounding factor.
