USE OF ILIZARAV EXTERNAL FIXATOL TO TREAT JOINT PTERYGIA

Joint pterygia are rare conditions characterized by joint-flexion cont ractures and webbing of the overlying skin and subcutaneous structures . Treatment is difficult because the neurovascular bundle is often dis placed into the web, and only moderate success has been reported with past treatment options. A retrospective review was performed on five p atients with six involved joints: two antecubital pterygia and four po pliteal pterygia. The Ilizarov technique was used for gradual correcti on of pterygia through the joint (arthrodiastasis). Primary treatment goals included improvement in functional extension, hygiene independen ce, and cosmesis. Ambulation was also an objective in the patients wit h popliteal pterygia. For inclusion in this study, a minimum of 2 year s' follow-up was required after the device was removed. Preoperative g oals were met in four of the six joints. Initial improvement in total are of motion was noted; however, some regression was common. Complica tions were frequent, and there was a learning curve for proficiency wi th the Ilizarov technique. We believe that the Ilizarov technique prov ides a treatment option for antecubital and popliteal pterygia.
