Bleeding complications following percutaneous tendoachilles tenotomy in the treatment of clubfoot deformity

Abstract

Ponseti demonstrated correction of most clubfeet in infants using proper manipulative techniques followed by application of well-molded long-leg plaster casts and a percutaneous tendoachilles tenotomy to correct residual equinus contracture. Medical complications occurring as a result of this technique have not to our knowledge been reported. The authors retrospectively reviewed 134 consecutive infants with 219 idiopathic clubfeet treated with the Ponseti method. A percutaneous tendoachilles tenotomy was performed on 200 clubfeet (91%) at a mean age of 16 weeks (range, 6-77 weeks) when less than 10 degress of ankle dorsiflexion was present after casting. A total of 4 patients had serious bleeding complications following the percutaneous tendoachillis tenotomy--3 due to presumed injury to the peroneal artery and 1 due to injury to the lesser saphenous vein. The authors detail the technique of performing a percutaneous tendoachilles tenotomy and offer guidelines that may help others avoid this same complication.
