What is Clubfoot?
• Talipes Equinovarus • Congenital Deformity or
acquired condition • Affects bones, joints,
muscles, and blood vessels • Occurs once per 1000 live
births is the U.S. • The foot is pointing
downwards and twisted inwards

More Facts on Clubfoot
• ~100,000 born each year in the world
• 5 to 7 times more children born with it in third world countries
• Almost half babies born with the condition have bilateral clubfoot
• In Uganda • 10,000 current cases
• 1,000 born each year
• Only one trained surgeon to treat condition
• Need a non surgical answer to the condition

Treatment Options
• Physiotherapy - The aim is to stretch the ligaments and tendons into the correct position.
• Strapping - Strips of adhesive strapping are passed around the foot, up the sides of the leg, and over the top of the knee, to hold the foot in a corrected position. This is usually done weekly, following some physiotherapy.
• Plaster fixation - The surgeon manipulates the foot into position, and holds it in place with plaster. This needs to be repeated about every week for 3 to 6 months.
• Ponseti Method - The treatment involves weekly stretching of the foot deformity in the clinic, followed by the application of long leg plaster casts. The cast is changed every 1 or 2 weeks. The physician may performs a tenotomy, an Achilles tendon lengthening using non-invasive surgery.
• Splinting - There are different types of splint available that may be worn just at night, or for most of the time.
Most reports only show a success rates of less than 50%. Almost all of the treatments need to be followed by a braces to hold the foot in
the correct position for an extend period of time.

Current Braces
Dennis Brown Bar
Wheaton Brace
Problems with current braces:• Expensive ($200 to $300)
• Uncomfortable
• Hard to keep children in them
• Parents will allow kids to take it off because cause discomfort
• They do not keep feet at optimal position
• DBB – both feet must be kept in brace

The Primary Objectives
• Fabricate an orthotic device to successfully treat patients (approximate age 1-3 years)
• Improve comfort and wearability of the orthosis
• Formulate a design to prevent distraction of the foot from the orthosis, as commonly occurs with currently marketed devices
• Construct a more economical device for non-invasive treatment to a costly health condition

Achievements to Date
• Guidance by Dr. Moreland on the condition and current methods of treatment
• Decided on a preliminary design
• Contacted companies about buying portions of the prototype from standard orthotic parts
• Obtained a Dennis Brown Bar to examine and model our device after

Conditions for Success
• Hard to find a infant with clubfoot to test prototype
• If the brace:• Holds the foot in the correct position for
extend periods of time
• Comfortable for infant to wear
• Cheaper than other braces on the market

Personal Role
• Brainstorm possible redesigns of device
• Construct prototype • Drawings of possible redesigns • Implement validation and verification
protocols on the prototype• Clinical evaluation of prototype
