Abstract
We report the clinical outcomes of children with complex congenital foot deformities treated with UMEX® mini-external fixators. This is a prospective review of our experience in patients treated in this way, from 2004. The indications for treatment were resistant/recurrent Congenital Talus Equina Varus(CTEV), cavo-varus deformity secondary to Charcot-Marie-Tooth disease, arthrogryposis, fibular hemimelia and other congenital abnormalities. In addition, one patient underwent this treatment since he was allergic to casting material.
A total of 32 children (35 feet) have been treated, with a male to female ratio of 22:10 respectively. The patient-age at operation ranged between 3 and 15 years (median age −7 years). Three patients underwent bilateral procedures and 29 patients underwent unilateral foot operations. Twenty-eight patients underwent previous soft-tissue and bony corrective operations with serial casting. The frames were removed at an average of 69 days after application with a further 6 weeks in a walking cast. Seventy-nine percent of the patients had good functional outcome. Further operations were needed in 10 patients. Complications occurred in 10 patients, including pin-site infections, bony overgrowth at pin-site and proximal tibio-fibular diastasis.
In conclusion, this is a simple fixator to use with a small learning curve. In groups of patients with complex congenital abnormalities, we achieved good functional outcome with low-complication rates.
