Retraction surgery for ankle osteoarthritis and talar osteonecrosis

    In 1995, the Dutch physician van Valburg et al. published a report in JBJS-Br entitled “Can Ilizarov joint distraction delay the need for an arthrodesis of the ankle? report”, studied 11 patients with traumatic osteoarthritis of the ankle, 0.5 mm/time, 2 times/day, with a 5-mm distraction, weight bearing and activity with a frame for an average of 15 weeks (12-22 weeks). The results noted a reduction in pain in all patients, an increase in mobility in 55%, and a widening of the joint space in 50%. The Ankle Osteoarthritis Scale (AOS) and the SF-36 Quality of Life Scale were significantly higher at 1 year postoperatively and 2 years postoperatively compared to preoperatively (p<0.05). Ankle distraction is still a relatively new surgical technique (less than 20 years since its introduction), and several clinical studies have reported the results of ankle distraction in the treatment of various diseases, mainly degenerative ankle osteochondral diseases, from different perspectives, and pointed out that ankle distraction can reduce pain, improve function, and relieve subchondral osteochondral sclerosis.
