Observation on pathological changes of the medial aspect of the first metatarsal head of hallux valgus

Objective: To observe pathological characteristic of bone and soft tissue of the medial aspect of the first metatarsal head in order to investigate the pathogenesis of hallux valgus. Methods: One hundred and twenty-three patients with hallux valgus(235 feet) were obtained from August 2003 to December 2004 in our department. The bone and soft tissue of the medial aspect of the first metatarsal head were taken out from the incision. The pathological conditions of specimen were observed by HE stain. Results: The pathological changes included:degeneration and desmoplasia around the attachment point of tendon and joint capsule,reactive hyperplasia of periost,decreasing of bone trabecula,cartilaginification of periost,cortical bone and tendon insertion,bone formation and osteoclasts response. Conclusion: The pathological changes of the medial aspect of the first metatarsal head of hallux valgus presented extensive chronic inflammation.
