Association of fibular hemimelia and clubfoot.

This study was designed to determine the incidence of clubfoot in our fibular hemimelia population. A retrospective review of fibular hemimelia patients treated at our institution over the past seventy years was conducted. We identified twenty-three cases of clubfoot in 121 patients with 147 involved limbs. Nineteen of twenty-three limbs retained the foot, four were converted to Syme's amputation because a plantigrade functional foot could not be obtained. Hindfoot coalitions were present in eighteen limbs and nineteen had one or more missing lateral rays. In summary, the association of clubfoot deformity with fibular hemimelia is more common than previously reported. It was not always evident to the surgeon treating these patients that fibular hemimelia syndrome was present in addition to clubfoot deformity. The presence of a coalition is a relatively constant finding in this condition and should be anticipated by the treating clubfoot surgeon.

Plasma total homocysteine level in mothers of children with clubfoot.

The pathogenesis of clubfoot is unknown despite numerous hypotheses. To clarify the relationship between the plasma total homocysteine level and congenital idiopathic clubfoot, blood samples from mothers of children with congenital idiopathic clubfoot (group 1) and mothers of children without congenital anomaly (group 2) were studied. Groups were the same for factors affecting the plasma total homocysteine level. Mean plasma total homocysteine level was 16.34+/-4.78 micromol/L in group 1 and 11.02+/-1.85 micromol/L in group 2, and there was significant statistical difference between the groups (P<0.05). Congenital idiopathic clubfoot showed a significant association with high plasma total homocysteine level. This study may be a step toward clarification of clubfoot pathogenesis.

Treatment of a recurrent clubfoot deformity after initial correction with the Ponseti technique.

Early recognition and appropriate treatment of recurrent deformity (relapse) is an important component of the Ponseti technique of clubfoot correction. After correction of a clubfoot deformity by the Ponseti technique, relapse usually involves equinus and varus of the hindfoot. Cavus and adductus rarely recur to a clinically significant degree. Clubfoot recurs most frequently and quickly while the foot is rapidly growing-during the first several years of life. Recurrence of deformity will almost always occur, even after complete correction with the Ponseti technique, if appropriate bracing is not used. Treatment of clubfoot relapse in infants and toddlers is identical to the original correction maneuver. In a patient approximately 2.5 years of age, a relapse can be treated with anterior tibial tendon transfer to the third cuneiform with or without Achilles tendon lengthening. The indication for anterior tibial tendon transfer is the presence of dynamic supination during gait. After tendon transfer, bracing is no longer required because the eversion force of the transferred tendon maintains the correction. In a long-term follow-up study of patients treated by the Ponseti technique, the necessity for anterior tibial tendon transfer did not compromise the outcome with respect to level of pain and functional limitations. Because anterior tibial tendon transfer is joint sparing, the foot retains maximal strength and suppleness. Good long-term results can be anticipated despite clubfoot relapse.

Clubfoot deformity in congenital constriction band syndrome: manifestations and treatment.

Clubfoot deformity associated with congenital constriction band syndrome (CCBS) has different characteristics than classic idiopathic clubfoot, and is more difficult to treat. We describe the manifestations, treatment, and outcomes of nine patients treated for 11 CCBS-associated clubfoot deformities between 1980 and 1993. All but one of these children had an abnormal gestational or neonatal history. From an assessment of the correctability of the deformity and the associated secondary changes, the clubfoot severities were all classified as grade B (intermediate). The constriction bands in eight clubfeet were classified as type 0 (5 feet), II (2), or III (1), according to the location and depth of the band. Band types in three feet were unclassified because the band release was performed at other hospitals. We released the bands before correcting the clubfeet in the two patients with type II bands. The five patients with type 0 bands received casting first but with poor response. All clubfeet were corrected surgically; the procedures were posteromedial release in 10 feet, split tibialis anterior tendon transfer in five, and lengthening of the Achilles tendon in three. At an average follow-up of 3.8 years, seven of the 11 clubfeet were classified as having good results and four as fair. Among the six clubfeet with constriction bands on the ipsilateral leg, five were classified as having good results and one as fair. Two of the five clubfeet without constriction bands on the ipsilateral leg had good results and three had fair results. The presence of a band did not influence the final outcome of the clubfoot deformity (p > 0.05). In the five patients with forefoot varus deformity due to peroneal weakness, tibialis anterior tendon transfer successfully corrected the deformity. All the clubfeet treated in this series were plantigrade after treatment and had satisfactory results.

Joint laxity and the risk of clubfoot.

BACKGROUND: Clubfoot is a relatively common and potentially disabling birth defect. The etiology of clubfoot (talipes equinovarus [TEV]) is not known. Joint laxity, or hypermobility, is a suspected risk factor for congenital hip dislocation and clubfoot. METHODS: We conducted a case-control study of TEV in five western Washington counties. A total of 239 cases of TEV were identified from hospital and outpatient sources from 1986 to 1994. Controls (n = 356) were identified by random-digit dialing (RDD). Parents were interviewed over the telephone, and medical records were abstracted. In-person measurements of four joint laxity indices in parents and the index child were obtained. RESULTS: Moderately elevated adjusted odds ratios (ORs) were found for extension > 90 degrees of the entire little finger, and extension of all four fingers to a position parallel to the forearm (OR = 1.6; 95% CI = 0.9-2.9; and OR = 1.7; CI = 1.1-2.5; respectively). No elevation in the OR was found for the wrist and elbow laxity measures. No consistent pattern of association between joint laxity measures in parents and an elevated OR of clubfoot among their children was found. CONCLUSIONS: The results of this study suggest a role for joint laxity in the etiology of TEV.

Sonographic assessment of clubfoot.

PURPOSE: This study was performed to develop a standardized methodology for the sonographic assessment of clubfoot at birth and at the end of both conservative treatment and surgical correction. METHODS: Forty-two congenital clubfeet and 42 normal feet were examined sonographically in the position of spontaneous alignment and during passive manual correction. Scans along 4 planes provided information relevant to the assessment: sagittal posterior, sagittal anterior, coronal lateral, and transverse. RESULTS: Sagittal posterior sonograms demonstrated the progressive gain of dorsiflexion ability during the different steps of treatment for clubfoot. Sagittal anterior sonograms could not demonstrate the normal alignment of the navicular in clubfeet because of the bone's medial displacement. On transverse sonograms, the talar head and the medially displaced navicular may lie on the same plane, depending on the severity of the deformity. Coronal lateral sonograms provided for estimation of the relationships between the calcaneus and cuboid, which were described by the calcaneal-cuboid angle. CONCLUSIONS: Sonography is a promising technique for assessment and monitoring of clubfoot during treatment. The method described here yields accurate and reproducible information about the anatomy of the nonossified clubfoot, helping the orthopedic team decide on appropriate treatment steps.

Stress radiography in the assessment of residual deformity in clubfoot following postero-medial soft tissue release.

X-ray is important in the assessment of clubfoot. Stress radiographs give more information than routine radiographs. Because of the inaccuracy of the positioning and the disadvantages of radiation, paediatric orthopaedic surgeons do not like and do not use X-ray examination. In this study we report a technique we use to obtain stress radiographs in paediatric patients with clubfoot using a custom-made radiolucent modular splint. This technique provides better assessment of the initial status and the result of treatment. Although this method has limitations it can help to compare different feet and treatment results with regard to axis and angle. We validated this splint by means of a prospective study in 11 patients with 21 feet having type 2 clubfoot who underwent (PMSTR) in our centre. Two sets of radiographs were taken, one with manual positioning and one with our splint. We found significant differences in the values of midfoot and forefoot radiological parameters between the two sets. We found that the correlation between the clinical and radiological assessment of residual deformity improved significantly for these values when a splint was used to obtain stress views. Hence we recommend routine use of a radiolucent splint for taking stress views to assess residual deformity in clubfoot.

Reduced tibial torsion in congenital clubfoot: CT measurements in 24 patients.

We determined leg torsion with CT scans through the femoral condyles and the ankle joints in 24 children (17 boys) with congenital clubfoot. In 16 cases, there was a bilateral clubfoot, in 5 cases it was left-sided and in 3 cases, it was on the right side. These children were compared to 17 healthy boys and 7 girls. The ages of all children ranged between 3 and 12 years. The average external torsion of the leg in the patients with clubfoot was 20 (15) versus 31 (7) degrees in the healthy children (p = 0.002). This study shows that there are great variations in leg torsion in children with congenital clubfoot and, on average, the external torsion is significantly lower than in healthy subjects.

Family history, maternal smoking, and clubfoot: an indication of a gene-environment interaction.

Although epidemiologic studies of some birth defects have suggested a gene-smoking interaction, the possibility of this interaction in clubfoot has not been examined. The authors analyzed risk factors among 346 infants with isolated clubfoot and 3,029 infants without defects from the Atlanta Birth Defects Case-Control Study. All infants were born during 1968-1980, and mothers were interviewed in 1982-1983. The authors examined the family history-smoking interaction as an indication of a gene-environment interaction. They defined "smoking" as smoking any time during the first 3 months of pregnancy and "family history" as having a first-degree relative with clubfoot. Conditional logistic regression (matching variables: race, birth hospital, and birth period) was used to obtain effect estimates. The adjusted odds ratios were 1.34 (95% confidence interval (CI): 1.04, 1.72) for smoking only, 6.52 (95% CI: 2.95, 14.41) for family history only, and 20.30 (95% CI: 7.90, 52.17) for a joint exposure of smoking and family history. The effect estimate for the joint exposure was higher than would be expected under either an additive or a multiplicative model of interaction and showed a statistically significant departure from additivity. This study confirms the importance of familial factors and smoking in the etiology of clubfoot and identifies a potentially important interaction.

Evaluation of the walking pattern in clubfoot patients who received early intensive treatment.

The walking pattern in a group of nine adult male subjects who had received early intensive treatment for congenital clubfoot was evaluated and compared to the walking pattern in a control group of 15 adult healthy male subjects. All subjects were filmed with a five-camera video system as they walked across two force plates. A three-dimensional inverse dynamics approach was used to calculate average joint angles, moments, power, and work. The results showed that there were no differences in the joint angles between the two groups. The overall patterns of the joint moments were very similar in the two groups. However, analysis revealed a smaller ankle joint moment and larger knee and hip joint moments in those with clubfoot. It was concluded that the larger knee and hip joint moments served as compensation for the smaller ankle moment. The reduced ankle moment and work developed about the ankle joint in the clubfeet could possibly be owing to weaker plantar flexors. In conclusion, gait analysis can be an important tool when evaluating treatment for clubfoot. However, further investigation is needed to determine whether the higher hip and knee joint moments observed in subjects with clubfoot may lead to the development of knee or hip joint pathologies.

Late recurrence of clubfoot deformity: a 45-year followup.

Idiopathic clubfoot is one of the most common congenital deformities. Regardless of the mode of treatment, clubfoot has a tendency to relapse until the age of 5 years. Relapses are rare in patients after 5 years of age. A 45-year followup of a patient with idiopathic clubfoot treated as a newborn with the Ponseti method is reported. The patient had both clubfeet well-corrected as seen clinically and radiographically with this method. However, recurrent deformities developed bilaterally when the patient was 8 years old. Because of the late recurrence of this deformity, the patient had a thorough neurologic evaluation, which was normal. Treating physicians should be aware of the possibility of late recurrence in patients who have had complete correction of their clubfoot deformity.

A method for the early evaluation of the Ponseti (Iowa) technique for the treatment of idiopathic clubfoot.

The Ponseti casting technique is reported to have a high success rate in the treatment of idiopathic clubfoot. Non-operative treatment of clubfoot provides a lower complication rate, less pain, and higher function as the patient ages than operative treatment. To demonstrate serial post-treatment change in clubfeet over time, three clubfoot rating systems were utilized in the current study. Patients compliant with the Ponseti technique and treated before the age of 7 months, had a 92% success rate at an early follow-up after casting was completed. It is not the purpose of this article to analyze the long-term clubfoot treatment result but to establish tools which can be used to judge initial success with the Ponseti technique. Complications are few and minor, limited to equipment used and cast technique.

Use of a soft tissue expander before surgical treatment of clubfoot in children and adolescents.

Primary closure of the skin after surgical correction of severe clubfoot is difficult, sometimes impossible. The authors describe a surgical technique with the use of a soft tissue expander prior to surgical treatment on clubfoot in children and adolescents. They operated on 13 feet (10 patients) with rigid clubfoot, with ages ranging from 3 to 16 years (average 10 years). Satisfactory skin healing with primary closure of the skin was obtained in 10 feet; the remaining 3 had complications such as infection, skin necrosis, and premature exposure of the expander. The authors conclude that soft tissue expansion before surgical correction of clubfoot in selected cases is a good alternative for the management of skin closure. Special attention should be given to surgical technique.

Talo-navicular arthrodesis for residual midfoot deformities of a previously corrected clubfoot.

Triangular navicular, dorsal-lateral subluxation of the talo-navicular (TN) joint with a secondary forefoot cavovarus deformity, and degenerative changes of the TN joint are frequent causes of residual clubfoot deformity and pain in the midfoot after surgical correction. This study investigates the usefulness of TN arthrodesis to correct these deformities and to resolve symptoms resulting from these deformities. During the period from 1991-1996, the senior author performed 19 TN fusions (16 patients) for the above residual clubfoot deformities involving a painful TN joint. Eight of the procedures (seven patients) also required a lateral column shortening with a calcaneal wedge osteotomy to allow for a complete correction of the TN joint. The procedure was only performed in cases involving a hindfoot that was adequately aligned during a previous clubfoot correction. The average age of the patients at the time of surgery was 11 years (range: 4-20). One patient (bilateral procedures) was lost to follow-up. Fifteen patients (17 procedures) were followed-up for an average of four years (range: 2-6). All patients reported symptomatic improvement after the TN arthrodesis. Fourteen of the patients (15 procedures) were completely satisfied. The remaining patient (bilateral procedures) was only partially satisfied due to the subsequent development of navicular-cuneiform osteoarthritis in both feet. Two cases (2 patients) developed complications requiring a second procedure for satisfactory results. In addition, the procedure resulted in an improvement of the talus-first metatarsal angle on both antero-posterior and lateral radiographs. TN arthrodesis produced a correction of the residual clubfoot deformities of the midfoot and resulted in satisfactory clinical improvement in all the patients.

A 30 year functional follow-up of a neglected congenital clubfoot in an adult: a case report.

Neglected congenital clubfoot in adults has been described in literature, but is not common to see adult patients with this orthopaedic disorder in developed countries with 30 years of follow-up. We report an asymptomatic case of neglected congenital clubfoot in an adult, who is incidentally seeking treatment for her 18-month-old son with congenital clubfoot. Although the cosmetic appearance is unacceptable, this mother remarkably has no functional limitations and for this reason she refuses any surgical treatment for her foot. To our knowledge, this is the first report of an untreated congenital clubfoot with 30 years follow-up.

Necrosis leading to amputation following clubfoot surgery.

Amputation after clubfoot surgery is a rare and catastrophic complication. This case report involves an amputation necessitated by postoperative necrosis on the medial side of the foot. To our knowledge, only one brief published report of necrosis following clubfoot surgery exists in the literature, and that report contains little clinical information. Although we know of several additional cases of necrosis following clubfoot surgery, the details of these cases remain unavailable to us for publication. The clubfoot deformity is almost always associated with vascular deficiencies involving the anterior tibial and dorsalis pedis arteries, as well as their derivatives. Since the area of necrosis in this case report coincided with the anatomic distribution of the derivatives of the congenitally reduced or absent dorsalis pedis artery, we suggest that insufficient blood flow to the dorsal and medial sides of the foot, and to the hallux contributed to the necrosis. In our opinion, the surgeon should assume that an abnormal vascular pattern, as described here, is present unless proven otherwise.

Role of Joshi's external stabilisation system fixator in the management of idiopathic clubfoot.

PURPOSE: To explore the role of Joshi's external stabilisation system fixator in correcting cases of clubfoot peculiar to India, we studied cases of neglected clubfoot, dropout cases of plaster-of-paris cast treatment, or failed surgical procedures that had been followed for a minimum period of 2 years. METHODS: 26 children underwent 44 Joshi's external stabilisation system procedures at the Central Institute of Orthopaedics at the Safdarjung Hospital, New Delhi, between January 1998 and December 1999 for the conditions of interest. Three-dimensional correction was achieved by use of the distractor device. RESULTS: Excellent results were obtained in 77% of the cases, good results in 13%, and poor results in 9% of the cases. Complications in half of the cases were pintract infections, which eventually healed on an outpatient basis without any residual sequelae. CONCLUSION: The Joshi's external stabilisation system frame is ideally suited for the child in whom clubfoot deformities remain uncorrected by plaster-of-paris casts and manipulation, as well as for recurrent clubfoot. Casting after complete correction not only protects the osteopenic bones while the pin-tracts heal, but also maintains correction and allows gradual weightbearing.

Kinematics and kinetics of the hip, knee, and ankle of children with clubfoot after posteromedial release.

Clubfoot is a bony deformity characterized by inversion, adduction, and equinus that often require surgical intervention. This study assessed the gait kinetics and kinematics of children with unilateral and those with bilateral clubfoot, comparing them with age-and gender-matched normal (control) children. Patient satisfaction also was examined using a questionnaire, and muscle strength was evaluated at the ankle and knee. In evaluating the kinematics, it was important to note that deviations occurred at the ankle of children with clubfoot. Differences in kinematics and kinetics at the hip and knee between normal children and those with clubfoot resulted from lack of motion at the ankle. Furthermore, the strength of ankle plantarflexors was weak, which reduced plantarflexion during push-off. This restricted motion may have been caused by residual bony deformities and muscle tightness resulting from the original condition that contributed to muscle stiffness during gait.
