Cerebral Palsy Foot Disorders
What are cerebral palsy foot disorders?
Foot disorders are common in children with cerebral palsy. The most common deformity is called equinus, or plantar flexion deformities. In this condition, the foot points downwards.
This deformity is often part of a larger lower extremity deformity. Specific foot deformities are:
- Equinovarus (neuromuscular club foot) - foot points downwards and inwards.
- Equinovalgus - foot points downwards and outwards.
- Planovalgus (neuromuscular flat foot) - foot is flat and points out to the side.
- Hallux valgus (neuromuscular bunion) - big toe points toward and sometimes under the second toe.
- Pes Cavus - High arch generally seen in neuromuscular populations.
Orthopaedic surgeons at Children's Hospital of Philadelphia (CHOP) design surgeries to correct as many contractures as possible during a single trip to the operating room. Casting is generally needed for several weeks after surgery. Our surgeons may use the following to treat your child's cerebral palsy foot disorders.
Muscle lengthening procedures may be performed surgically to improve joint motion and gait (walking), and to prevent deformities.
Lengthening procedures can also be used to decrease the need for bony surgery in younger children, and reduce tone on a more permanent basis than botulinum toxin (Botox).
Where botulinum toxin and medical management can globally or focally weaken a spastic muscle, they cannot alter its pull. Tendon transfers allow muscles to be partially transferred to a different location in the joint, which can improve balance of the forces across a joint.
Bony reconstruction allows for direct restoration of anatomic position of joints or relief of rotational abnormalities which result in brace intolerance.
In cases where the deformity is too severe to be managed with simple realignment, fusion can provide a durable option to provide long-term support of a patient’s skeleton.
Foot bracing may also be useful. When our orthopaedic surgeons prescribe a brace for your child, our expert orthotists will create the customized brace.
