Brief Summary:
The purpose of this study was to determine the influence of cast material on correction of congenital idiopathic clubfeet using the Ponseti method.

Condition or disease Intervention/treatment Phase
Clubfoot Ponseti Method Talipes Equinovarus Casting Device: Plaster of Paris (POP) casting using the Ponseti Method Device: Semi-Rigid Fiberglass softcast using the Ponseti Method Not Applicable

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.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 30 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Comparison of Two Different Cast Materials for the Treatment of Congenital Idiopathic Clubfoot Using the Ponseti Method: A Prospective Randomized Controlled Trial

Arm Intervention/treatment
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

Primary Outcome Measures :
  1. 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 ]

Secondary Outcome Measures :
  1. need for percutaneous tendo-achilles tenotomy
  2. total time in casts (weeks)
  3. ease of cast removal
  4. time of cast removal [ Time Frame: number of minutes required for each cast removal ]
  5. method(s) of cast removal
  6. other concerns about the casting material (e.g. appearance, weight, cleaning, water resistance), and complications relating to the casting material.
