Ponseti clubfoot treatment has become more popular during the last decade. We reviewed the medical records of 74 consecutive infants (117 club feet) who underwent Ponseti treatment. Minimum followup was 5 years (mean, 6.3 years; range, 5-9 years). We studied age at presentation, previous treatment, the initial severity score of the Pirani scoring system, number of casts, need for Achilles tenotomy or other surgical procedures, and brace use. We measured final ankle motion and parents' perception of outcome. Late presentation and previous nonPonseti treatment were associated with lower initial severity score, fewer casts, and less need for tenotomy.

Therapeutic study, Level IV (Case series). See the Guidelines for Authors for a complete description of levels of evidence.

Serial casting is successful in avoiding extensive posteromedial release (PMR) in only 11% to 58% of patients with idiopathic congenital clubfoot. Extensive open surgery is commonly associated with long-term stiffness and weakness. Ponseti claims to avoid PMR in 89% of cases by using his specific technique of manipulation, casting, and limited surgery. The authors report their first 27 patients undergoing the Ponseti technique (34 feet) with a group of 27 matched control patients (34 feet). All patients underwent serial casting, begun within the first 3 months of life. The parameter studied was the need to perform PMR within the first year of life. In the Ponseti group, only 1 (3%) of 34 feet required PMR. In 31 (91%) of 34 feet, percutaneous Achilles tenotomy was performed at age 2 to 3 months. The average duration of casting was 2 months. In the control group, 32 (94%) of 34 feet required PMR within the first year of life, despite a longer casting period. Based on the authors' initial success with the Ponseti method, they no longer believe that PMR is required for most cases of idiopathic clubfoot. Foot abduction splints are crucial to avoid recurrence. Longer follow-up will determine whether the authors can continue to match Ponseti's reported outcomes.

The Ilizarov external fixator has numerous advantages applicable to ankle fusion, including: stable fixation, respect for soft tissues, and the possibility of postoperative alignment 'fine-tuning'. Additionally, the ability to direct forces through or around skeletal elements allows varying of the load through the skeletal elements, allowing early weightbearing. The Ilizarov technique, with its high union rate, may be considered for any ankle arthrodesis but is especially useful in complex cases such as revisions, talar osteonecrosis, soft-tissue compromise, and infection. Early weightbearing is an added benefit.
