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.
