The X-ray Analysis of Metatarsal Seed Arthritis of 162 Patients (302 feet) with Hallux Valgus

Objective:To observe the existence of metatarsal seed arthritis and the X-ray features of metatarsal seed arthritis of patients with hallux valgus.Methods:3 orthopedists above vice-senior title observe and analyze X-rays and clinical manifestations of metatarsal seed joint of 162 patients(302 feet) with hallux valgus independently to ascertain the presence or absence of metatarsal seed arthritis and to clarify the features of manifestation of the metatarsal seed arthritis in patients of hallux valgus.There views were summarized finally.Results:Radiologic manifestations of osteoarthritis widely were existed in X-ray of metatarsal seed joint in 302 feet of 162 patients with hallux valgus.There are 268 feet with dysarthrosis or subluxation,and 254 feet with asymmetric stenosis in joint gap,231 feet with subchondral bone sclerosis,129 feet with cystic degeneration,199 feet with hyperosteogeny and formed osteophyte,0 foot with loose body.There are 20 feet of grade 0,52 feet of gradeⅠ,53 feet of gradeⅡ,137 feet of gradeⅢ,40 feet of grade Ⅳ,according to the classification of Kellgren and Lawrence;and there are 256 feet according with the diagnostic criteria of metatarsal seed arthritis.Conclusion:Deformity of hallux valgus can result in metatarsal seed arthritis.
