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...

Subtalar dislocations without bone fractures show good functional outcomes. The direction of the injury did not impact clinical or radiographic results in this study.

Area of Science:

  • Orthopaedic surgery
  • Trauma care
  • Foot and ankle injuries

Background:

  • Subtalar dislocations without associated bone injury are under-reported in medical literature.
  • This study focuses on evaluating outcomes for this specific type of foot and ankle injury.

Purpose of the Study:

  • To assess the functional and subjective results of patients with subtalar dislocations lacking associated bone trauma.
  • To determine if the direction of dislocation influences patient outcomes.

Main Methods:

  • Retrospective review of 97 subtalar dislocations treated between 1994 and 2007.
  • CT scans identified 23 cases without associated bone injury.
  • Patients underwent clinical and radiographic follow-up averaging 58.3 months post-treatment, using the AOFAS ankle-hindfoot scale.

Treatment of Ankle Osteoarthritis with Total Ankle Replacement Through a Lateral Transfibular Approach

Published on: January 24, 2018

Main Results:

  • The average AOFAS score was 82.3, with 21 good and 2 satisfactory outcomes.
  • Average subtalar joint range of motion was 41.3 degrees.
  • No significant difference in outcomes was noted between medial and lateral dislocations; only 6 patients showed minor radiographic changes.

Conclusions:

  • Subtalar dislocations without bone injury demonstrate good intermediate-term results.
  • The direction of the dislocation (medial vs. lateral) does not appear to affect clinical or radiographic outcomes.
