Congenital talipes equinovarus (CTEV)

Talipes, literally "ankle-foot", refers to the talusEquinovarus refers to the position of the clubfoot, in equinus and varus or adductus

3

Congenital deformity1 of 1000 babiesOne or both feetboy : girl = 2 : 11st trimester of pregnancyThe foot pointing downwards and twisted inwardsClub, "kidney shaped", with a prominent medial crease along the plantar aspect of the foot

4

5

Clubfoot does not cause pain in the infantIt gets worse over time, with secondary bony changes developing over years

6

An uncorrected clubfoot in the older child or adult is very unsightly, and worse, very cripplingThe patient walks on the outside of his foot which is not meant for weight-bearingThe skin breaks down, and develops chronic ulceration and infection

7

Two variations: 1) positional deformities

caused by the position of the foot in the womb

2) structural malformations where bones, joints, muscles, and blood vessels are malformed

8

Whether positional or structural, there are four common types of clubfoot

9

• Clubfoot can be recognized in the infant by examination

• The foot is inturned, stiff and cannot be brought to a normal position

• Children with the condition should be referred to an orthopedic surgeon for complete evaluation and treatment of the deformity

10

Treatment

very important to treat clubfoot as early as possible (i.e. shortly after birth) to prevent disability and problems with walking when the child gets older

11

The first step is taping/casting of the footThe physician holds the foot in the proper position and then puts tape or cast on to hold it in place One-third of feet, usually the ones more mildly affected, will respond to this therapyDuring the immediate postnatal period, the cast or tapings are changed every day

CASTING

12

child will be seen frequently by the pediatric orthopedic surgeon: every one to two weeksInitial treatment is provided by a series of casts to the affected foot

13

Infants are placed in casts covering the entire limb(s)The severity of child's deformity will determine the number of casts requiredThe casts will need to be kept dry

14

After multiple serial castings are completed (2-3 months), special shoes with or without a bar may be needed

15

The Pediatric Orthopaedic Surgeon lengthens several of the tendons (structures which connect muscle to bone) which allows to foot to adopt a normal position

SURGERY

Achilles lengthening procedure

If cast treatment fails, surgery is necessaryThis is not performed until the child is between four and eight months of age

16

The Operation

patient is anesthetizedpositioned pronea tourniquet applied to the proximal limbthe limb is surgically scrubbed and drapedreleases and reductionsone or two K-wires are inserted by drill, to hold the reduced and corrected position, to fixate the talonavicular and calcaneocuboid jointsthen are shortened and bent externallyThis makes for easy removal, and eliminates danger of migration

17

Steri-strips and a dressing are applied and a plaster of Paris backslab long leg splint is appliedMost surgeons do not splint the foot in the completely corrected position initiallyThis is to allow for expected post-operative soft tissue swelling and to prevent ischemia of the footThe limb is then elevatedThe hospital stay is commonly just one nightPain and circulation status must be under control before discharge

18

One week after surgeryunder general anesthetic or sedation,the splint is removedthe foot is examined

19

a circumferential long leg cast is applied in the over-corrected position of heel dorsiflexion,pronation of the foot and external rotation of the ankleThe knee is placed at 90 degrees of flexion

20

Sometimes orthotic fitting is done at this time for a knee-ankle-foot orthotic (KAFO) OR an ankle-foot orthotic (AFO)The device will be worn for months

21

If a KAFO is used, it will eventually be replaced by an AFO to allow the baby to walk. These are worn inside shoes

Bilateral AFO orthotics
