[Dislocation of the peroneal tendons].

Dislocations of the peroneal tendons are more common than they are diagnosed. Probable reasons for misinterpretation of the injury are the hidden position of the peroneal tendons behind the malleolus lateralis and the tendency to self-reduction of the peroneal tendons. Insufficient treatment leads to a chronic recurrent peroneal tendon dislocation which is not necessarily accompanied by pain. However, if the instability of the peroneal tendons is painful, surgical treatment is advised. Various surgical methods are described in the literature. Nearly all report good postoperative results. In case of chronic recurrent peroneal tendon dislocation, we prefer the surgical management described by Viernstein, namely, mobilisation of connective tissue of the region, leading it over the peroneal tendons and suturing it in a bone pouch of the malleolus lateralis. The advantages of this surgical method are that it does not damage important anatomical structures of the region and that no second operation to extract implants is necessary. We treated 13 patients by the method described by Viernstein. 12 of 13 patients have resumed sports activities. We have not seen any redislocation of the peroneal tendons.
