In the past 8 yesrs, the authors have treated 4 cases of traumatic dislocation of peroneal tendons in Nagasaki Mitsubishi Hospital. All of these were old cases, and they were treated by operative therapy with Du Vries' method. Even through a long period of follow-up, there was no evidence of mobile bone fragment absorption. Neither was there a complaint about limited range of ankle motion, nor were the incidents of pain and redislocation observed. With all the cases, therefore, the results were highly satisfactory. Du Vries' method, limiting the dislocation of the peroneal tendon from outside the joint and yet capable of completely preventing the dislocation of tendon, can be said to be an excellent technique.
