Ankle Joint

3.7K
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.

    Subtalar arthrodesis effectively improves hindfoot scores and achieves bony union. Bone grafting enhances talocalcaneal height and angle, but posttraumatic arthritis increases risks of Reflex Sympathetic Dystrophy.

    Area of Science:

    • Orthopedic Surgery
    • Foot and Ankle Reconstruction

    Background:

    • Subtalar arthritis significantly impacts patient mobility and quality of life.
    • Isolated subtalar arthrodesis is a surgical option for managing severe subtalar joint dysfunction.

    Purpose of the Study:

    • To review outcomes of isolated subtalar arthrodesis in adults.
    • To compare clinical results between posttraumatic and other etiologies of subtalar arthritis.
    • To evaluate the impact of bone grafting on surgical outcomes.

    Main Methods:

    • Retrospective review of 33 adult patients undergoing isolated subtalar arthrodesis.
    • Comparative analysis based on etiology (posttraumatic vs. other) and use of bone grafting.
    • Assessment of clinical outcomes using the AOFAS hindfoot score and radiographic union.

    Main Results:

    • Mean AOFAS hindfoot score improved from 46 to 77.3 postoperatively.
    • Thirty-one of 33 arthrodeses achieved bony union at a mean of 15.7 weeks.
    • Bone grafting significantly improved talocalcaneal height (8.1 mm vs. 3.8 mm) and angle compared to non-graft procedures.

    Conclusions:

    • Isolated subtalar arthrodesis yields favorable clinical outcomes and high union rates.
    • Bone grafting enhances radiographic correction in subtalar arthrodesis.
    • Patients with posttraumatic subtalar arthritis face a higher risk of developing Reflex Sympathetic Dystrophy.
