Specific brace-fitting complications in idiopathic congenital talipes equinovarus (CTEV) have been rarely described in published series, and usually focus on non-compliance. Our primary aim was to compare the rate of persistent pressure sores in patients fitted with Markell boots and Mitchell boots. Our additional aims were to describe the frequency of other brace fitting complications and identify age trends in these complications. A retrospective analysis of medical files of 247 idiopathic CTEV patients born between 01/01/2010 - 01/01/2021 was performed. Data was collected using a REDCap database. Pressure sores of sufficient severity for clinician to recommend time out of brace occurred in 22.9% of Mitchell boot and 12.6% of Markell boot patients (X2 =6.9, p=0.009). The overall rate of bracing complications was 51.4%. 33.2% of parents admitted to bracing non-compliance and 31.2% of patients required re-casting during the bracing period for relapse. For patients with a minimum follow-up of age 6 years, 44.2% required tibialis anterior tendon transfer. Parents admitting to non-compliance were significantly more likely to have a child who required tibialis anterior tendon transfer (X2=5.71, p=0.017). Overall rate of capsular release (posteromedial release or posterior release) was 2.0%. Neither medium nor longterm results of Ponseti treatment in the Australian and New Zealand clubfoot have been published. Globally, few publications describe specific bracing complications in clubfoot, despite this being a notable challenge for clinicians and families. Recurrent pressure sores is a persistent complication with the Mitchell boots for patients in our center. In our population of Australian clubfoot patients, tibialis anterior tendon transfer for relapse is common, consistent with the upper limit of tibialis anterior tendon transfer rates reported globally.
1. The movements of the talus are described with particular reference to the anatomy of congenital talipes equinovarus. 2. It is suggested that the fundamental deformity in severe club foot is the fixed plantar-flexion of the talus. 3. Early operation is advised whenever serial stretching fails to bring the heel quickly into its normal position.
Congenital talipes equinovarus (CTEV), also known as club foot or talipes is a common congenital disorder. Parents are using the Internet more and more as a source of information about health care. Unfortunately, the quality of health care information on the Internet varies. This study looked at information available to parents using two instruments for judging the equality of information on the internet. The top five search engines were searched on Google. Three of these were also included in the top 50 sites in Ireland so these 3 sites were used. The phrases CTEV and club foot were searched from all 3 platforms. Websites were then scrutinized using the HON code and the DISCERN tool. 54 organic sites were found for the 3 search engines using the key word club foot. For the key word CTEV 55 matches were returned for the three search engines. 4 websites displayed the HON code. Using the discern tool CTEV websites had a mean score of 60 with a standard deviation of 17. While club foot had a mean score of 56.8 with a standard deviation of 13. Max score 80. Large volumes of information are available to parents on the Internet. Often parents find comfort in sharing experiences and feel empowered by learning about their children's illnesses. However, information provided on the interned can also be ambiguous and disingenuous. Practitioners should be aware of a number of key websites that parents can be directed towards.
From mid-1992 to 2000 and in conjunction with our paediatric department, we have run a screening program to detect congenital orthopaedic abnormalities. Over this period, we have been referred 245 patients with a provisional diagnosis of clubfeet, of these 54 or 22% were true CTEV (78 feet) giving an incidence in the general population of 0.18% while the rest were diagnosed as having simple postural clubfoot (0.6%). Each patient was assessed clinically and classified according to the Harrold and Walker scale as well as being checked for other congenital/neurological abnormalities. 83% of patients were seen within two weeks of referral. Initial management entailed strapping for 6 weeks with further periods of plaster immobilization (required by 46%). Those who failed to respond or who deteriorated underwent surgical correction with sub-talar release. A small percentage required secondary procedures such as Tibialis Anterior transfer, Tendoachillis release and revision. Patients were continued in the program until at least 6 years of age. While there was a wide variation of other abnormalities in those with type 2 CTEV, those with type 3 had a high incidence of neurological conditions and in particular, arthrogryphosis (59%). These patients did worse and 55% required further surgery after the initial sub-talar release. We would like to present the findings of an 8.5 year prospective study looking at the incidence of the condition, the frequency of other abnormalities and the results of conservative and surgical treatment for each grade.
Relapse rate of both treatment methods was compared for all feet in all Dimeglio grades. Relapse rates for Ponseti and surgery respectively were: grade 2, 18.2% vs 0%; grade 3, 36.2% vs 20.4%; grade 4, 35.3% vs 65.4%. The differences were not statistically significant
This is the first study in the Ponseti-era to compare severity and outcomes in cases of idiopathic congenital talipes equinovarus (CTEV) diagnosed antenatally versus those diagnosed at birth. Small pre-Ponseti studies showed antenatal diagnosis to be a predictor of severity and poor prognosis. Prospective data collection was used to compare indicators of severity and outcomes for idiopathic CTEV between these two groups. These include Pirani score, number of casts, follow-up Roye score and need for surgery. 68 children with 106 affected feet were included. Antenatal diagnosis (AD) was made in 45 children (71 feet), with birth diagnosis (BD) in 23 children (35 feet). Mean follow-up age was 4.8 years (AD = 4.9, BD = 4.7), male:female ratio 2:1 (AD=BD) with bilateral CTEV in 55% (AD = 58%, BD=52%). Mean initial Pirani scores were 5.25 in the AD group vs 4.86 in the BD group (p=0.06). Mean Roye score at follow-up was 1.39/4 in the AD group vs 1.26/4 in the BD group (p=0.33) with 33% vs 30% complaining of pain respectively (p=0.80). Surgery was needed in 11/71 (15.5%) in the AD group vs 1/35 (2.9%) in the BD group (p=0.06)) There is no significant difference in severity between antenatal and birth diagnoses of idiopathic CTEV and no difference in outcomes between these groups when treated with the Ponseti regime. Although small, our sample size is greater than the largest published comparable study.
The Ponseti regime was introduced in Swansea in 2003 for the treatment of congenital Sixty children (89 feet) were treated with the Ponseti regime between 2003 and 2010. Their notes were compared with notes from 12 children (21 feet) treated between 1995 and 2002. Clinic attendance for serial manipulation and immobilisation (strap/cast) was compared using a two-tailed Mann Whitney U test. Major release surgery was compared using a two-tailed Fisher's Exact test.Introduction
Materials and Methods
It is difficult to predict the outcome or likely treatment that will be required for an individual child with a rigid clubfoot deformity at an early stage. 32 Dimeglio grade II, III or IV CTEV feet in 24 infants were treated with weekly serial casts according to Ponseti method. Graphical plots of the improvement obtained in Dimeglio scores during serial cast treatment of CTEV were subsequently analysed to identify characteristic features that would help predict the likely success of casting or the need and extent of surgical release. The rate of change in global Dimeglio score, hindfoot (equinus / heel varus) and midfoot (adduction / derotation) components were specifically studied. During casting the rate of change over 4 weeks and a “plateauing” of the global Dimeglio score after 4–6 weeks of casting separated those feet that responded to casting alone from those that required additional surgery. Those with “plateauing” and minimal midfoot deformity by 4 weeks (adduction /derotation score <
=2) required a posterior release. Failure to correct the mid-foot deformity by 4 weeks (adduction /derotation score >
= 3) predicted the need for a combined plantar medial and posterolateral release. These parameters were clearly demonstrated by graphical plots that can be easily obtained in a busy clinic setting. Graphical representation of the rate of change in Dimeglio parameters can predict the likely treatment needed for children with CTEV. A graphical algorithm has been developed that can be used during the first 6 weeks of treatment to guide Ponseti method casting and early surgical intervention.
From a cohort of 110 idiopathic clubfeet, 26 feet in 18 children requiring surgery for severe relapse have been studied. Surgery was comprised of a lateral column shortening procedure (Lichtblau) plus or minus a plantarmedial release. Surgery was staged to avoid wound complications. Pre-operatively, feet were prospectively categorised into one of four grades according to a system reported by Dimeglio. Children were reviewed on two subsequent occasions. At review, feet were again graded. In addition, appearance and functional outcome was analysed and included an assessment of gait, activity and functional limitation. Three children were lost to follow-up, leaving 22 feet in seven male and eight female patients available for review. The mean age at surgery was 43 months (23–82). The mean time from surgery to first and second reviews was 35 and 56 months, respectively. There was a significant improvement in grading at first review compared to pre-operative grading (Wilcoxon signed ranks test). Although there remained a significant improvement in grading at second review compared to the preoperative grading, there was a significant reduction in the number of feet in which grading had improved when compared to first review. There was no significant change in function between the two post-operative reviews (Chi-square tests), with the majority of children experiencing little functional limitation. There were no wound complications. Relapse surgery, involving a lateral column shortening procedure for severe clubfoot, results in a significant initial improvement when assessed using a grading system. This improvement in grading subsequently decreases over time. However, the functional outcome in such cases remains favourable.
The Cincinnati incision is widely utilized in clubfoot surgery and allows excellent access to the medial, lateral and posterior structures involved. Closure of the skin at the end of the procedure without undue tension may be difficult. Wound necrosis and excessive scarring may occur and may lead to inadequate correction. One alternative is to splint the foot in an initial equines position post-operatively with repeat cast changes to achieve optimal position once soft tissue swelling has decreased. A further method is to leave the wound open and allow it to granulate. The healing and final cosmetic appearance of wounds allowed to heal by granulation following the Cincinnati incision were reviewed. We reviewed 14 feet in 10 patients who had undergone partial closure of the Cincinnati incision following peritalar release. The majority of the children were male and the average age at surgery was 28 weeks. All corrections were performed as primary procedures on patients with idiopathic CTEV. At the end of the procedure an above-knee plaster was applied. The plaster was changed weekly in the outpatients department until the wound had healed. Patients were maintained in plaster for 12 weeks. All final wounds were cosmetically acceptable both to the surgeon and the parents. The widest scar was 3 mm and the average time to heal four weeks. No infection had occurred although two wounds were treated for overgranulation. Partial wound closure of the Cincinnati incision avoids undue tissue tension and allows a fully corrected position of the foot to be maintained at the end of the initial procedure. A second anaesthetic to obtain further correction is therefore avoided. Partial wound closure leaves cosmetically acceptable scarring with minimal complications. Parents should be warned about the initial appearance of the wound but may be reassured regarding final outcome.
It is difficult to predict the outcome or likely treatment that will be required for an individual child with a rigid clubfoot deformity at an early stage. 32 Dimeglio grade II, III or IV CTEV feet in 24 infants were treated with weekly serial casts according to Ponseti method. Graphical plots of the improvement obtained in Dimeglio scores during serial cast treatment of CTEV were subsequently analysed to identify characteristic features that would help predict the likely success of casting or the need and extent of surgical release. The rate of change in global Dimeglio score, hindfoot (equinus/heel varus) and midfoot (adduction/derotation) components were specifically studied. During casting the rate of change over 4 weeks and a “plateauing” of the global Dimeglio score after 4–6 weeks of casting separated those feet that responded to casting alone from those that required additional surgery. Those with “plateauing” and minimal midfoot deformity by 4 weeks (adduction/derotation score <
=2) required a posterior release. Failure to correct the mid-foot deformity by 4 weeks (adduction/derotation score >
= 3) predicted the need for a combined plantarme-dial and posterolateral release. These parameters were clearly demonstrated by graphical plots that can be easily obtained in a busy clinic setting. Graphical representation of the rate of change in Dimeglio parameters can predict the likely treatment needed for children with CTEV. A graphical algorithm has been developed that can be used during the first 6 weeks of treatment to guide Ponseti method casting and early surgical intervention.
