Primary clinical evaluation of the joint replacement for the treatment of the first metatarsophalangeal arthritis / 中国医学科学杂志(英文版)

ABSTRACT

<p><b>OBJECTIVE</b>To retrospectively assess the primary clinical results of a cohort of the first metatarsophalangeal joint replacement with double-stemmed hinge silicone implant.</p><p><b>METHODS</b>A total of 12 patients (15 feet) received the joint replacement with double-stemmed hinge silicone implant. There were 2 males and 10 females with a mean age of 61.4 (range, 56-75) years old. Of them, 9 cases (11 feet) were hallux valgus with osteoarthritis; 1 case (2 feet) was rheumatic arthritis; 2 cases (2 feet) were traumatic arthritis. The subjective and objective results were evaluated during follow-up.</p><p><b>RESULTS</b>All of the patients were followed up regularly with an average of 24.7 months, ranging from 12 to 38 months. Ten patients were completely satisfied with the operation; 1 patient showed partial satisfaction, and 1 patient was not satisfied because of the first matatarsophalangeal joint pain due to severe hyperosteogeny surrounding the cut bone surface 3 years after the operation. Osteolysis around the implant occurred in 2 cases without clinical symptoms, and no special treatment was given.</p><p><b>CONCLUSION</b>The joint replacement is a preferable method in alleviating pain and improving walking function with proper indication.</p>
