Évaluation à  moyen terme d'une intervention type hémi-Castaing dans le traitement de l'instabilité chronique de cheville

The treatment of chronic instability of the ankle by hemi-Castaing ankleplasty associated with articular cleaning is a satisfactory intervention for the surgeon as well as for the patient. It makes possible the recovery of a stable and functional ankle. The pain, however, will not totally disappear, which the patient should be told before the operation. Mastering the tension of the plasty is the main difficulty of this intervention, which may fail, but not necessarily as a result of the plasty's being too loose. The cause for the failure should also be sought in other factors related to the region of this pathology (deltoidian ligament, neurologic trouble, proprioceptive).
