Further study details as provided by Alberta Children's Hospital:

Primary Outcome Measures:
  • number of casts required to correct the clubfoot deformities [ Time Frame: time required for the foot to be ready for a percutaneous tendo-achilles tenotomy (if necessary), or when dorsiflexion of the ankle greater than or equal to 15 degrees (Pirani=0) was achieved ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • need for percutaneous tendo-achilles tenotomy [ Designated as safety issue: No ]
  • total time in casts (weeks) [ Designated as safety issue: No ]
  • ease of cast removal [ Designated as safety issue: No ]
  • time of cast removal [ Time Frame: number of minutes required for each cast removal ]
  • method(s) of cast removal [ Designated as safety issue: No ]
  • other concerns about the casting material (e.g. appearance, weight, cleaning, water resistance), and complications relating to the casting material. [ Designated as safety issue: No ]

Enrollment: 30
Arms Assigned Interventions
Active Comparator: Plaster of Paris (POP) Device: Plaster of Paris (POP) casting using the Ponseti Method
Active Comparator: semi-rigid fiberglass softcast (SRF, 3M Scotchcast) Device: Semi-Rigid Fiberglass softcast using the Ponseti Method

Detailed Description:

Congenital idiopathic clubfoot is the most common congenital deformity in children. It can be a major cause of disability for children, as well as an emotional stress for parents. The Ponseti method of clubfoot correction, consisting of serial manipulations and casting, is now the gold standard of treatment. It has traditionally been described using plaster of Paris (POP) above-knee casts; however, recently semi-rigid fiberglass softcast (SRF, 3M Scotchcast) has grown in popularity. There are currently no randomized controlled trials to prove its efficacy with respect to POP.
