Tarsometatarsal fractures and dislocations

A total of 32 cases of tarsometatarsal fracture dislocations, treated during a 15-year period, have been retrospectively reviewed. Results were assessed in 29 patients with a mean age of 33.8 years and a mean follow-up of 6.3 years. On the basis of Quénu and Küss' classification, five patients had homolateral dislocations, three had divergent dislocations, and 21 had partial dislocations (seven medial partial and 14 lateral partial). Treatment included closed manipulative reduction, occasionally followed by Kirschner (K)-wire fixation. If closed reduction was not achieved, open reduction was performed. Results were assessed according to Hardcastle's scoring system. On that basis, 20 good, 5 fair, and 3 poor results were obtained and there was one early amputation. Good results were associated with an accurate reduction. Open treatment is advocated if minor displacement persists. Routine K-wire fixation is advised for all cases.
