Abstract
BACKGROUND
Treatment of idiopathic congenital talipes equinovarus (CTEV) is challenging for pediatric orthopedic surgeons. The Ponseti method is an effective protocol for treatment due to its technique of manipulation, casting, and limited surgery. Plaster casting is an essential component of the Ponseti method. In this report, we describe a new brace that was developed for use in the treatment of clubfoot in newborns instead of a plaster cast.
METHODS
This retrospective study was performed in two orthopedic medical centers. Between January 2011 and October 2013, 89 newborns with CTEV (131 ft) underwent corrective treatment using fixation braces in the experiment group (E-group) in our hospital, and 107 newborns with CTEV (141 ft) underwent plaster casting in the control group (C-group) in another medical center. All patients were treated according to the Ponseti method after the application of the inclusion and exclusion criteria. Plaster casts were applied to patients in the C-group. The patients in the E-group received the custom-made polyaxial fixation braces instead of plaster casts. Prospective follow-up was performed for a mean duration of 36 months. The efficacy of the treatment was assessed using Pirani's scoring system. Chi-squared and independent t tests were used for statistical analyses.
RESULTS
In the E-group, 85 patients (125 ft) achieved good appearance within 3 months of treatment initiation (average, 1.7 months). Four patients (6 ft) required percutaneous Achilles tenotomy. Seven patients developed sores during treatment because of improper brace application, but all sores healed without scarring with timely treatment. In the C-group, 96 patients (123 ft) achieved good appearance within 3 months of treatment initiation (average, 1.6 months). Eleven patients (18 ft) required percutaneous Achilles tenotomy. Twenty-one feet developed sores during treatment because of plaster cast pressure on the dorsum of the feet. Sixteen sores healed without scarring with timely treatment, and 5 ft had obvious scars. The overall mean Pirani scores 1 year after treatment were 0.26 ± 0.06 in the E-group and 0.25 ± 0.03 in the C-group, and the Pirani scores 3 years after treatment were 0.23 ± 0.05 in the E-group and 0.22 ± 0.03 in the C-group. There were significant differences in the percutaneous Achilles tenotomy and skin sores but no significant difference in the Pirani scores between these two groups.
CONCLUSIONS
Our results showed that the new polyaxial fixation brace used in this study was an effective tool for the corrective treatment of CTEV in newborns. We propose the use of this brace as an alternative treatment for newborns.
