CONFERENCE COVERAGE: International Clubfoot Symposium

The Ponseti method of clubfoot management has achieved worldwide 
acceptance, but practitioners and researchers are still working to identify the best ways to optimize clinical outcomes while remaining sensitive to issues of cost effectiveness and cultural differences. Clinicians from around … Continue reading

Resource-poor areas benefit from global outreach efforts

Treatment of children with clubfoot has evolved considerably in the five years that have elapsed since the inaugural International Clubfoot Symposium, and the benefits of this evolution are particularly evident in resource-poor nations—home to about 80% of the 200,000 children born each year with clubfoot. But practitioners who treat patients in these areas still face financial, cultural, and logistical challenges.

Benefits of Ponseti method extend to older children

Clubfoot correction ideally should be performed during infancy, before children learn to walk, but experts agree that the Ponseti treatment method can also be effective in older children. Speakers at the International Clubfoot Symposium in October presented successful outcomes for Ponseti treatment of neglected clubfoot in patients aged up to 21 years.

TATT in relapsed clubfeet can affect plantar flexion

Tibialis anterior tendon transfer (TATT) is known to be associated with limited ankle dorsiflexion, but practitioners should be aware that plantar flexion also can be negatively affected, according to research presented in October at the International Clubfoot Symposium.

Energy efficiency with AFO use varies in cerebral palsy patients

Longer strides lead to increased work
Ankle foot orthoses (AFOs) are regularly prescribed to children with walking disabilities resulting from cerebral palsy, yet the effects of AFOs on energy recovery and work during gait are still unclear.

Biomodel could help researchers optimize clubfoot brace design

Method includes complex rotations
A surrogate biomodel of a child’s lower extremities, in particular the ability to model movement along multiple axes of rotation, could help improve researchers’ biomechanical understanding of bracing for clubfoot.

Juvenile idiopathic arthritis study reveals footcare information gap

Issues involve custom foot orthoses
A Scottish study suggests foot care in children with juvenile idiopathic arthritis (JIA) falls short because of poor access to care and negative perceptions about custom foot orthoses. Experts say those issues may be less prevalent in the US but emphasize the need to educate patients, parents, and referring clinicians about the benefits of lower extremity care.

Early ACL surgery could lower risk of associated knee damage

Patterns mirror those seen in adults
Timing of reconstruction surgery after pediatric anterior cruciate ligament (ACL) injuries seems to be related to the prevalence of meniscal and chondral injuries discovered during those surgeries, according to new research published in the September issue of The American Journal of Sports Medicine.

Dynamic data in obese children may suggest gait compensation

Low force values surprise researchers
An Austrian study exploring the role of genu valgum and flatfoot in obese and normal weight children found obesity was associated with higher peak plantar pres­sures, but lower maximum force while walking, when forces were normalized to body weight.

Future of Orthotic Design will focus on practitioners

Foot orthotic laboratories have long been the principal players in the computer aided design and computer aided manufacturing (CAD-CAM) of foot orthoses. But practitioners are gradually starting to play a bigger role in the process—a development that dramatically enhances the potential for clinical creativity but also introduces an extra element of uncertainty.

OPTIMIZING ORTHOTIC MILLING

Computer aided manufacturing is anything but a one-size-fits-all proposition. Customers have a range of variables to choose from, and making the right decision in most cases depends on knowing what type of orthotic material the machine will be asked to handle.

Additive manufacturing inches toward prime time

The fledgling field of additive manufacturing is still somewhat fragmented, as evidenced by the fact that the same technology can be described as rapid prototyping or 3D printing. But additive manufacturing’s profile is definitely on the rise, and its advocates are optimistic that lower extremity clinical applications are right around the corner.
