Abstract
Tarso-metatarsal injuries are rare but frequently missed. Due to the large variation in pathomorphic forms of these injuries, great precision is required when carrying out clinical and X-ray diagnostic procedures. The aim of the study was to describe the different forms of Lisfranc joint injuries and analyse the causes of delayed treatment. The treatment results of acute and chronic injuries were compared in 41 patients, with an average follow-up period of 16 years. Statistically significant poorer results were obtained in the group of chronic cases, based on two functional scores - the AOFAS evaluation questionnaire and the Lublin functional questionnaire. The main factor delaying the start of the proper treatment was diagnostic error during initial admission. The best results were achieved after closed reduction and percutaneous Kirschner wire fixation in acute cases.
