Abstract

Peri-tarsal dislocation occurs rarely and it has a complex joint structure anatomically. So, the injuries of the tarsal joint include many bony and ligament injuries and many complications such as pain on weight bearing and limitation of joint motion. The authors have reviewed a series of 15 cases of Peri-tarsal dislocations and the results obtained are as follows;1. Among the 15 cases of peri-tarsal dislocations, subtalar dislocation were 2 cases, Chop-art dislocation was 1 case, Lisfranc dislocation were 11 cases, and pure ankle dislocation was 1 case. 2. There were 12 cases of associated tarsal bone fractures 6 cases were cuneiform fractures, 4 cases were navicular fractures, and 2 cases were cuboid fractures 3. The clinical and radiological result of treatment was good in 3 cases, fair in 6 cases, and poor in 6 csses. 4. The cause of poor results were open dislocation, associsted tarsal bone fractures, delay of treatment, unstable reduction, and associated long bone fractures. 5. The most common complications after treatment were pain on weight bearing and limitation of joint motion.
