| Abstract: | BackgroundFirst tarsometatarsal arthrodesis, or known as modified Lapidus arthrodesis, is a powerful procedure for hallux valgus correction. Historically there have been high reported complication rates including nonunion, dorsiflexion malunion and transfer metatarsalgia, due to the high lever at the TMT I joint.MethodsThe development of new biomechanically more stable fixation methods has revolutionized the classic Lapidus arthrodesis in recent decades, so that more progressive mobilization regimens could be established.ResultsThe current clinical and radiological results of modern Lapidus arthrodesis using plate fixation confirm that nonunion rates could be drastically reduced. However, the rates of symptomatic transfer metatarsalgia remained unchanged.ConclusionOn the basis of new fixation methods, the modified Lapidus arthrodesis became a low-complication and satisfactory surgical method. The influence of first ray shortening and dorsiflexion malunion on the development of a transfer metatarsalgia has not yet been fully clarified. |
