Persistent Clubfoot Deformityy A clubfoot that has not been fully corrected and will NOT fit into or b controlled be t ll d iin an ankleankle kl -foot f t orthosis th i (AFO). (AFO) It will ill therefore th f lead l d to failure or full recurrence and the patient may present with: 1. Equinus – most common 2. Midfoot adduction 3. Varus of the heel 4. Cavus deformity 5. Midfoot rocker bottom deformity Recurrent Clubfoot Deformityy A fully corrected clubfoot maintained in a proper AFO that shows evidence of a recurrent (relapse) d f deformity it severall months th or years after ft treatment. t t t The patient may present with: Recurrent Clubfoot Deformityy (cont.) 1. Heel elevation – equinus 2. Rocker bottom deformity – midfoot dislocation (midfoot breach – Noonan) through the talonavicular and calcaneocuboid joints 3 Cavus 3. C d deformity f i 4. Varus of the calcaneus 5. Callus at lateral aspect of the foot 6. Inability to shoe correctly, i.e. due to recurrent deformity 7. Midfoot adduction – navicular not corrected over the talus 8. Forefoot adduction – adduction through g Lisfranc’s jjoint 9. InIn-toeing gait – corrected clubfoot and flexible foot with overactive anterior tibial tendon 10.

Complete recurrence to original clubfoot deformity 10 Most Common Causes of Persistent or Recurrent Clubfoot Deformities 1. Feet prone to persistent or recurrent deformities. deformities Such as: A. Clubfoot due to unrecognized syndrome i.e. arthrogryposis B. Complex or atypical clubfoot described by Morcuende and Ponseti Short first toe Bean--shaped foot Bean Plantar crease Ponseti technique will fail unless modified Ponseti, 1996 Oxford University Press Most Common Causes of Persistent or Recurrent Clubfoot Deformities (cont.) C Patient initially treated after seven months of age? C. D. D Unrecognized neurological clubfoot ii.e. e spastic or paralytic deformity (Frick, S. Drop Toe Sign. COOR.2009 COOR.2009)) E. Foot previously treated with “supposed” Ponseti technique that failed (Helig: Current Management of Idiopathic Clubfoot Questionnaire. JPO 2003 JPO, 2003)) (26 26..2% correction with the Ponseti technique) Most Common Causes of Persistent or Recurrent Clubfoot Deformities (cont.) 2. Failure to maintain correction – usually a deformity that was uncorrected and forced into an AFO 3. Noncompliance with regard to use of the DB bar (AFO?) Treatment of Persistent Clubfoot Deformity: A Uncorrected An U t dF Foott Treated T t d by b the th Ponseti P ti Technique T h i 1. Start from the beginning using all the steps of the Ponseti technique 2. This may require more casts than the usual foot and each step of casting ti may have h tto b be repeated t d severall titimes Treatment of Persistent Clubfoot Deformity: A Uncorrected An U t dF Foott Treated T t d by b the th Ponseti P ti Technique T h i 3. Percutaneous tenotomy may have to be repeated as well. Note: The tenotomy is only done when the head of talus is covered by the navicular navicular. Otherwise a rocker bottom deformity may occur. The head of the talus can be felt laterallyy when not covered. Dobbs/Schoenecker; JPO,Vol24, No.4,2004 Treatment of Recurrent Clubfoot Deformity: A Previously P i l C Corrected t dF Foott The first decision to be made is - which part of the deformity has recurred? Attention must then be directed to that part of the foot. • Equinus – the foot is corrected except that dorsiflexion cannot go beyond neutral position. Decide from the following: A Physical therapy – French method? A. B. Recasting C. Repeat percutaneous tenotomyy D. Posterior release – Formal: Includes Achilles tendon release (Strayer procedure), ankle j i t release, joint l and d release l off th the subtalar bt l jjoint. i t Treatment of Recurrent Clubfoot Deformity (cont.) Midfoot Adduction Chopart’s joint A. A Mild deformity may persist throughout life and may only require intelligent neglect B. If it occurs early after treatment, recast being sure to cover head of talus, followed by maintenance with AFO fitted into a shoe for walking Treatment of Recurrent Clubfoot Deformity (cont.) • Midfoot Adduction C If persistent C. persistent, may require release of adductor muscle muscle, surgical release of talonavicular joint, plus or minus a release of the first cuneiform -navicular D. In older children ((5 5-10 y years of age), g ) it may be necessary to perform a calcaneocuboid fusion or a first cuneiform opening wedge osteotomy and a closing wedge cuboid osteotomy, or a complete midtarsal osteotomy calcaneocuboid fusion McHale 1991 E. If associated with heel varus, a closing wedge osteotomy of the heel may be necessary in addition to the other procedures – what we refer to as a triple osteotomy involving the cuneiform, cuboid and calcaneus Dwyer Treatment of Recurrent Clubfoot Deformity (cont.) • Metatarsus Adductus F Before maturity – soft tissue Lisfranc’s F. Lisfranc s release (Heyman) Not effective After maturity a transmetatarsal osteotomy or triple arthrodesis may be necessary Transmetatarsal osteotomy Triple arthrodesis Treatment of Recurrent Clubfoot Deformity (cont.) • Cavus Deformity A Under the age of 5 – Soft tissue and/or plantar release; A. B. Over the age of 5 – Plantar release and base of the first metatarsal osteotomy and heel osteotomy or midtarsal osteotomy. Kösse, 1999 Treatment of Recurrent Clubfoot Deformity (cont.) • In In--toeing Gait If foot is fully corrected (not stiff) and gait is related to overactive anterior tibial tendon and weak peroneal power, the anterior tibial tendon may be transferred to the lateral or medial cuneiform after the age of 5 when the cuneiform is ossified Anterior tibial tendon transfer Treatment of Recurrent Clubfoot Deformity (cont.) • InIn-toeing Gait Due to a Supinated Midfoot • This means that the navicular is not completely covering the head of the talus. This must first be corrected by casting and/or a talonavicular release, and then laterally transferring the anterior tibial tendon. Do not transfer the tendon if the foot is stiff and the midfoot is not corrected. The tendon will not move a fixed foot. • If internal tibial torsion persists, tibial osteotomy (?) Tibial osteotomy Treatment of Recurrent Clubfoot Deformity (cont.) • Rocker oc e Bottom otto Deformity eo ty This is due to aggressive dorsiflexion of the foot against g a hindfoot contracture. A Stop treatment and allow the midfoot to correct itself or cast in A. a vertical talus position B Release the hindfoot B. hindfoot, Achilles tendon and posterior structures structures, and cast in a congenital vertical talus position C A fixed C. fi d rocker k b bottom tt deformity d f it is i difficult diffi lt tto treat t t and d may require aggressive management, similar to releasing a vertical talus Treatment of Recurrent Clubfoot Deformity (cont.) • Major Recurrence “A la carte” treatment as reported by the late Dr Dr. Henri Bensahel Bensahel. Each patient must be treated y, and in most cases individually, tendon releases, hindfoot releases, and/or midfoot releases will do. It is rarely l necessary tto perform f a complete subtalar release that was popular in the past and very often resulted in stiff, painful feet. Treatment of Recurrent Clubfoot Deformity (cont.) • Major Recurrence – gradual external fixator correction In summary: Gentle manipulation of the clubfoot +/+/- percutaneous Achilles tenotomyy (Ponseti ( technique) q ) will be effective if done p properly p y in all clubfoot deformities at least 80 - 90 90% % of the time. Persistence off clubfoot f deformity f is most likely due to incomplete correction of the deformity. Recurrent deformity has to be addressed depending upon which p part of the deformity y recurs and when. Bibliography for Persistent Clubfoot Deformity Following Treatment by Ponseti Method. 1.
