Hallux valgus surgery. Morton and Lapidus were right!

More than 60 years ago an anatomist, Dudley Morton, and an orthopaedic surgeon, Paul Lapidus, independently published similar theories that implicated excessive mobility of the first metatarsal in forefoot dysfunction. Morton first studied in detail the evolution of the foot leading to bipedal gait and then examined the feet of many of his students in an attempt to correlate his tentative assumptions with the presence of or lack of symptoms. Morton's analysis of forefoot dysfunction provides the foundation of modern surgical procedures that restore normal forefoot balance and function to asymptotic feet.
