Following joint distraction, ankle function was observed to decline over time, according to study results published in The Journal of Bone and Joint Surgery.
A clinical investigator evaluated 36 patients who underwent ankle distraction surgery between December 2002 and October 2006. Patients completed the Ankle Osteoarthritis Scale (AOS) and SF-36 surveys. At follow-up visits, researchers obtained radiographs, as well as CT and MRI scans of the ankles.
Overall, the researchers followed 81% of the patients for a minimum of 5 years and found 55% of the patients still had the native ankle joint, and 45% and had undergone either ankle arthrodesis or total ankle arthroplasty.
Results showed a better AOS score at 2 years, older age at surgery and fixed distraction as positive predictors of ankle survival. Progression of ankle osteoarthritis at the time of final follow-up was found with radiographs and advanced imaging, according to the researchers. – by Casey Tingle
