Ankle arthrodesis and tibial lengthening for congenital sensory neuropathy with anhidrosis.
This report describes a patient with congenital sensory neuropathy with anhidrosis (CSNA) with destructive arthropathy of the left ankle joint that was treated with ankle arthrodesis and tibial lengthening, using an Ilizarov external fixator. The fusion at the ankle joint was successful, but, at the lengthening site, loosening of the apparatus occurred and formation and maturation of the distracted callus were delayed. Intramedullary nailing was used after the removal of the external fixator, and a low-intensity ultrasound device was employed, after which the distracted callus matured gradually. During the maturation period, the patient's dysplastic right hip joint was destroyed, without the occurrence of any severe symptoms. Distraction osteogenesis in patients with CSNA may lead to good results if rigid fixation, nonweight-bearing (i.e., adequate rest), and appropriate biological stimulation can be employed.
