Summary
Ankle fusion is effective for elderly patients with ankle arthritis, showing good union rates and satisfactory function. This surgical option provides a viable alternative for older individuals experiencing severe ankle pain.
Area of Science:
- Orthopedic Surgery
- Geriatric Medicine
- Reconstructive Surgery
Background:
- Ankle arthrodesis is the standard surgical treatment for ankle arthritis unresponsive to conservative care.
- Previous studies on ankle fusion outcomes have not specifically focused on elderly patient populations.
- The study addresses the need for data on ankle fusion efficacy in individuals over 70.
Purpose of the Study:
- To evaluate the outcomes of ankle fusion in patients aged 70 years and older.
- To assess the functional results and complication rates of ankle arthrodesis in a geriatric cohort.
Main Methods:
- Retrospective review of 30 patients (30 ankles) over 70 who underwent ankle fusion.
- Postoperative assessment using the Foot and Ankle Ability Measure (FAAM) and American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score.
- Radiographic evaluation for union and progression of adjacent joint arthritis, with an average follow-up of 2.2 years for union and 8.5 years for functional outcomes.
Main Results:
- Achieved union in 90% (27/30) of ankles.
- Postoperative FAAM score averaged 81.5, with patients reporting 75.1% of their pre-arthritic function.
- AOFAS hindfoot score averaged 73.0; 36.6% showed progression of subtalar arthritis.
Conclusions:
- Ankle fusion demonstrates effectiveness in treating ankle arthritis in patients over 70.
- Functional outcomes are satisfactory, and union rates are comparable to younger populations.
- Ankle arthrodesis remains a valuable surgical option for elderly patients, even with the rise of total ankle arthroplasty.

01:10Ankle 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...
