Résumé
<p><b>OBJECTIVE</b>To summmarize the clinical experience of open reduction and internal fixation for the treatment of tarsometatarsal joint injury ane evaluate the effects of operative treatment to tarsometatarsal joint injury.</p><p><b>METHODS</b>From March to July in 2009,9 patients with tarsometatarsal joint injury were treated by open reduction and internal fixation included 7 males and 2 females with an average age of 33.5 years old ranging from 20 to 47 years. According to Quenu-Kuss classification, there were 5 cases of type A, 3 of type B, 1 of type C. All patients were treated by cannulated screws and Kirschner wires through 1 to 2 microtubule straight incision on dorsum of foot. The foot function were assessed by American Orthopaedic Foot and Ankle Society (AOFAS) midfoot score.</p><p><b>RESULTS</b>All patients were followed up for 5 to 12 months with an average of 8 months. Complications concluded 1 case with infection, 1 case with post-traumatic arthritis. The failure of Kirschner wires was not discovered in 9 cases. According to AOFAS system,the total scores increased from preoperative (15.5 +/- 4.2) to postoperative (92.0 +/- 5.2) (t = -45.95, P < 0.01). The results were excellent in 7 cases, good in 1, and poor in 1.</p><p><b>CONCLUSION</b>Open reduction and internal fixation for the reatment of tarsometatarsal joint injury should have satisfying results.</p>
