Primary Outcome Measures:
  • The rate of successful clubfoot correction from a single Botox injection. This coincides with entrance into Boots and Bars. This was measured 8 weeks following injection. [ Time Frame: 8 weeks ]

Secondary Outcome Measures:
  • Secondary outcomes of the study as outlined in protocol (include time of measurement) [ Time Frame: See protocol ]
  • Secondary Outcomes: Patient outcomes collected at every patient visit including: [ Time Frame: See protocol ]
  • 1. Ankle range of motion (dorsiflexion and plantarflexion) (collected at every visit) [ Time Frame: See protocol ]
  • 2. Heel Bisector Scores (collected at every visit) [ Time Frame: See protocol ]
  • 3. Pedobarographs (every 6 months from 18 months to 5 years) [ Time Frame: See protocol ]
  • Gait Analysis (every 2 years from 5 years of age until skeletal maturity) [ Time Frame: See protocol ]

Estimated Enrollment: 50
Study Start Date: September 2005
Estimated Study Completion Date: June 2016
Estimated Primary Completion Date: June 2016 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: Botox
    All patients meeting the inclusion criteria will undergo manipulation and casting until hindfoot stall is encountered. Hindfoot stall is defined as forefoot abduction to 60 degrees but persistence of hindfoot equinus. At hindfoot stall, subjects received Botox injections at 10 IU/kg into the gastrosoleus muscle complex. Following injections, subjects were recasted.
