Clubfoot Or Congenital Ta...


What Is Clubfoot Or Congenital Talipes Equinovarus Or CTEV?

The clubfoot deformity is often referred to as congenital talipes equinovarus (CTEV). Congenital clubfoot is a rigid deformity present at birth characterized by ankle equinus, heel tilt into varus, and midfoot and forefoot adduction with varus tilt. There is usually an additional equinus at the midfoot level referred to as cavus and associated underdevelopment of the calf musculature.

Causes Of Clubfoot Or Congenital Talipes Equinovarus Or CTEV.

A specific cause of the deformity has not been identified. The term idiopathic is used to refer to clubfoot where no other congenital abnormalities are seen. The large majority of patients have idiopathic or isolated clubfeet. The deformity has been considered  to occur secondary to: 

·         Congenital abnormalities of muscle.

·         Congenital skeletal defects.

·         Spinal defects like meningomyelocele.

·         Developmental Delay (Arrested Fetal Development).

·         Abnormal Insertion of Tendons.

·         Tarsal developmental anomalies or arrests.

·         Increased risk for an infant whose mother smoked in the first trimester.

Types Of Clubfoot Or Congenital Talipes Equinovarus Or CTEV.

  •            Extrinsic type

Less severe deformity with an elevated heel and is less mobile and easy to correct by manipulation.

  •     Intrinsic type

Severe deformity with a small heel and extremely resistant to treatment and tends to relapse.

 Pathological changes

The changes are most evident in the talus and calcaneum, navicular cuneiform joints, talonavicular are also contracted. The calf muscle underdevelopment usually persists into adulthood even with full correction and function of the former clubfoot; this indicates it to be a part of the pathologic process rather than a secondary disuse phenomenon.


Clinical Features Of Clubfoot Or Congenital Talipes Equinovarus Or CTEV.


The shape and contour of the foot undergoes changes, the ligaments and muscle are also contracted.

  •    The foot becomes smaller.
  •    Heel poorly developed.
  •    Crease along the medial border of the foot.
  •    Equinus deformity at the ankle.
  •    Adduction deformity at the tarsometatarsal joints.
  •    Varus deformity at the subtaloid joint.
  •    Medial malleolus is buried and in depression.
  •    Lateral malleolus is very prominen.


Diagnosis Of Clubfoot Or Congenital Talipes Equinovarus Or CTEV.

Antero posterior and lateral plain radiographic projections have been most commonly used to assess the degree of deformity and correction in clubfoot.


Ultrasound is capable of detecting up to 80% of clubfeet.

Computerized tomography (CT) scans provide accurate quantifiable information about the three-dimensional aspects of a clubfoot deformity.

Magnetic resonance imaging (MRI) is particularly effective in imaging abnormal cartilage and bone structure.

 The physiotherapist plans the treatment after assessing the foot.

·         The foot is held in hand and manipulated  gently to see if it can be brought into normal position, if not        then there is a positive diagnos
     Cavus:  The height of the medial arch is increased.

     Adduction: The direction of adduction is more towards the midline.

    Varus:  The angle formed by the line passing through the heel and the line passing through the midline       IS decreased.

    Equinus: The plantar flexion is increased.

Conservative Treatment For Clubfoot Or Congenital Talipes Equinovarus Or CTEV.

The treatment should begin in the first few weeks of life. The deformities should be treated step by step firstly adduction, then inversion and then equinus.

Techniques used by the physiotherapist

·         Ponseti’s technique.

·         Rhythmic and repeated gentle manipulation.

·         Gentle stretching.

·         Strapping and Plaster of Paris (POP).

Ponseti’s technique

The foot is supinated to align it and the calcaneus with the navicular. This supination is maintained as the talonavicular position is improved by abduction toward and then beyond the neutral plane. It is Ponseti’s recognition of medial foot column plantar flexion and the need to invert the entire foot to align all metatarsals in the same plane in the initial phase of manipulation differentiates his method of manipulation from others. Once adduction and inversion have been corrected, however, percutaneous Achilles tenotomy is done to correct equinus if it does not respond quickly to serial manipulation into dorsiflexion rather than the much more prolonged stretching with repetitive casts and wedging is done. Once the foot has been corrected, great emphasis is placed on maintaining the correction with full-time bracing for 3 months and nighttime bracing for 2–4 yrs Well-molded long leg casts are applied every 4–7 days. The short leg cast is applied first from toes to just below the knee and this is then converted to a long leg cast to upper-thigh with the knee flexed to a right ankle and
the leg externally rotated to correct tibial torsion.

To correct the varus deformity

The affected side knee is placed at 90o flexion to prevent damage to the lower end of tibial and fibular epiphyses, and the knee joint. Then the soft tissues of the right foot is passively stretched, the forefoot is flattened. Thus correcting the adduction. Then the foot is turned such that the sole is faced outward i.e eversion, thus correcting the inverted foot. The strectch is given for 2 minutes and repeated five times.

To correct the equinus (plantar flexion deformity)

The heel is cupped with the right hand from the front of the foot and upward pressure is applied to it bringing the forefoot upward. This brings the ankle into dorsiflexion. Each manipulation lasts for about two minutes and the entire procedure is repeated five times.


To maintain the feet in the corrected position, strapping is done. One therapist can stabilize the baby’s limb and the other can carry out the procedure. Strapping begins by holding the manipulated right foot to the overcorrected position. The first strip is applied from the medial border of the midpoint of the right leg down under the ipsilateral heel then along the lateral border of the leg to the lower 1/3 of the thigh with the knee flexed at 90o. This is to correct the heel varus deformity by eversion of the foot.

The second strip is applied over the dorsum of the mid-foot from lateral to medial then under the sole back to the lateral border of the mid-foot then along the border of the leg over the lower 1/3 of the thigh with the knee still at 90o. This is important to correct the equinus deformity abduction of the forefoot.

To bring the ankle into dorsiflexed position, the third strip is applied over the dorsum of the forefoot from lateral to medial, then along the plantar surface of the forefoot to the lateral border of the leg over the lower 1/3 of the thigh. The last strip is applied circumferentially around the leg at a point 2cm above the ankle joint. This is to correct the bowstring appearance of the lower 1/3 of the leg, the ankle, and the foot, and to increase eversion. At the end of the procedure, the therapist can wait and observe the limb for 30 minutes to check for any compromise to circulation. A layer of cotton wool (the rolled type in layers), enough to cover the malleoli was applied at medial and lateral malleoli of both ankles to avert pressure sore; Where the strips of the straps were circumferentially applied, in-between spaces were avoided to prevent window oedema. The strips of the straps should be smoothly applied and no wrinkles are permitted, to prevent skin excoriation.  For the first six weeks, the baby is seen thrice a week and strapping applied twice per week. From the period the baby is 7 to 12 weeks, the strapping is done once per week.

Plaster of Paris

At three months improvement will be seen. Baby at third month by this period (that is when the baby is three months), the strapping is no more effective because he can kick vigorously with the lower limbs. It was then replaced with a full leg plaster of Paris (POP) with the knees at 90o of flexion. The plaster was changed weekly for the first eight weeks of application and the knees and feet mobilized on each occasion. Thereafter it was applied and changed forth-nightly for another eight weeks. The plaster was finally removed when the baby was exactly seven months. At eight months and three weeks, he started standing with support and a good plantigrade position. At the thirteenth month, the baby can walk.

Family Education.

Counseling and support for the family is an important aspect of management. The mother should be assured that her co-operation and consistency is needed for the treatment of the deformity. She is made to understand that it is a gradual process and that she should follow up the case beyond when the baby starts walking. She is taught how to mobilize the foot in the absence of a strap. She is instructed to closely observe the limb for any swelling or bluish coloration. She is also advised to prevent the strapping or plaster from being wet or soiled either by water or any other fluid such as urine or faeces
