Dislocations of the peroneal tendon and posterior tibial tendon are comparatively rare disorders. They tend to become habitual and require caution. For the dislocation of the peroneal tendon, the Das de procedure is widely accepted since it incurs minimal sacrifice of other structures. Here we report our modified Das de procedure for tighter fixation of the peroneal or flexor retinaculum. With this procedure, the peroneal or flexor retinaculum is incised at the anterior attachment, the bursa is refreshed, then the retinaculum itself is sutured.
We treated 14 patients with this procedure from October 1997 to April 2004 and report the clinical results here. The pationts consisted of nine males and five females with a mean age of 20 years (14 to 35 years), and mean follow-up period of six months (0.5 to 28 months). Thirteen patients had peroneal tendon dislocation (11 patients tore their superior peroneal tendon and two tore the inferior one) and one had posterior tibial tendons dislocation. Symptoms more or less reduced in all cases, but only one patient had redislocation.
Often injuries of the ankle joint without fracture are treated as sprains. It is therefore difficult to distinguish whether the tear is of the superior or inferior peroneal tendon in the dislocation of peroneal tendon, and diagnosis and therapy play important roles for this injury.
