The influence of laterality, sex and family history on clubfoot severity

Clinical Characteristics and Whole Exome Sequencing Analysis in Serbian Cases of Clubfoot Deformity-Single Center Study

BACKGROUND

Recognized as one of the most serious musculoskeletal deformities, occurring in 1-2 per 1000 newborns, 80% of clubfeet are idiopathic while 20% present with associated malformations. The etiopathogenesis of clubfoot is described as multifactorial, including both genetic and environmental risk factors. The aim of this study was to analyze possible genetic causes of isolated and syndromic clubfoot in Serbian children, as well as to correlate clinical and genetic characteristics that would provide insight into clubfoot etiopathogenesis and possibly contribute to global knowledge about clinical features of different genetically defined disorders.

METHODS

We evaluated 50 randomly selected, eligible children with clubfoot aged 3 to 16 years that were initially hospitalized and treated at University Children's Hospital between November 2006 and November 2022. The tested parameters were gender, age, dominant foot, affected foot, degree of deformity, treatment, neuromuscular disorders, positive family history, and maternal smoking. According to the presence of defined genetic mutation/s by whole exome sequencing (WES), patients were separated into two groups: positive (with genetic mutation/s) and negative (without genetic mutation/s).

RESULTS

Seven patients were found to be positive, i.e., with genetic mutation/s. A statistically significant difference between categorical variables was found for families with a history of clubfoot, where more than half (57.14%) of patients with confirmed genetic mutation/s also had a family history of genetic mutation/s (p = 0.023).

CONCLUSIONS

The results from this study further expand the genetic epidemiology of clubfoot. This study contributes to the establishment of genetic diagnostic strategies in pediatric patients with this condition, which can lead to more efficient genetic diagnosis.

An Insight on Current Clubfoot Management: A Reported Data From Lebanon

BACKGROUND/AIM

Clubfoot, which has been reported in the literature since the time of Hippocrates in 400 BC, is regarded as one of the most difficult congenital orthopedic anomalies, with a high relapse incidence of 16.87 infants per 10,000 births. The Lebanese region holds limited data concerning the evolution of clubfoot management. Herein, we aim to present novel findings in the treatment of clubfoot without surgical intervention.

MATERIALS AND METHODS

This single-center, cross-sectional research included 300 patients with virgin idiopathic clubfoot treated at our facility from 2015 to 2020. The Pirani and DiMeglio Scores were used to determine the severity of the illness prior to treatment, and the DiMeglio Score was used to determine the severity of the disease after treatment. For data analysis, the Statistical Package for Social Sciences (SPSS, IBM-Version 26; IBM Corp., Armonk, NY) was used and results with p-value < 0.05 were considered statistically significant.

RESULTS

Our study included 300 patients, with 188 boys (62.7%) and 112 girls (37.3%). The mean age of the patients' onset was 32 days. We recorded an average initial Pirani score of 4.27 ± 0.65 and an average initial DiMeglio score of 11.58 ± 2.56 (62 out of 300) while the average final DiMeglio score was 2.17 ± 1.82. The mean number of casts was 5 ± 0.8, with a minimum of four and a maximum of six casts. The prevalence of relapse was 20.7%.

CONCLUSIONS

Clubfoot remains a challenging deformity with a high rate of treatment failure and recurrence. While the superiority of Ponseti's technique in terms of success rate could not be disputed, tailored therapy based on the patient's socioeconomic status is considered critical for compliance and treatment success.

Factors Predictive of Tenotomy After Ponseti Casting for Idiopathic Clubfoot: A Tertiary Care Center Study

INTRODUCTION

Parents of children with clubfoot are likely to inquire about the need for tenotomy and about any factors that may be predictive. The present study was done to identify factors that may help predict the need for tenotomy in children undergoing Ponseti treatment for idiopathic clubfoot.

METHODS

A prospective observational study was conducted on patients under 5 years of age with idiopathic clubfoot and no previous treatment history treated at Hospital and Rehabilitation Centre for Disabled Children. The relationship between the Pirani score, Dimeglio score, age, and passive ankle dorsiflexion (DF) and the need for heel cord tenotomy was analyzed using appropriate statistical methods.

RESULTS

Of 83 patients (125 feet) with a mean age of 6 months, 93 feet (74.4%) required a percutaneous tenotomy. The mean initial Pirani and Dimeglio score for 125 club feet was 4.5 (SD=1.68) and 13.5 (SD=6.1), respectively. The mean initial passive ankle DF was -40.4 (SD=22.31). The Dimeglio ( P =0.000), Pirani scores ( P =0 .000), and passive ankle DF ( P =0.000) showed significant association with the need for tenotomy.

CONCLUSIONS

This study shows a strong association between initial Pirani and Demiglio scores and initial passive ankle DF as predictive of a heel cord tenotomy. However, age, sex, and laterality were not associated with the need for tenotomy.

Congenital Talipes Equinovarus: Results of Treatment and Are We Bracing Effectively?

The aim of this retrospective study was to assess our management of Congenial Talipes Equinovarus (CTEV) in relation to national standards published by the British Society for Children's Orthopaedic Surgery (BSCOS). A secondary aim was to evaluate if a more tailored bracing regime than advocated in the traditional Ponseti technique, would be appropriate for some cases of CTEV. One hundred and thirty-three feet in 96 patients were treated between June 2006 and January 2016. All patients were clinically assessed prospectively by the senior author at initial presentation using the Harrold & Walker classification system. A combination of the senior author's database, Elogbook and trust IT systems were used for data collection. The results of Ponseti surgical procedures such as tendoachilles release and tibialis transfer fell within the BSCOS guidelines. The rate of radical subtalar surgical release was higher than advocated (12.3%) which was partly due to the number of primary syndromal patients in the series. There was a significantly lower mean time spent in bracing of 14.3 months (95% confidence interval 14.8-19.3) compared to recommended national guidelines. There was a clinically significant difference in the lower relapse rate of female patients compared to male patients and also a higher propensity of surgical intervention in male patients. In addition, there was a statistically significant difference in both time spent in bracing, between H&W classifications and between patients who had bracing removed pre walking age or post walking age. This potentially demonstrates a more tailored bracing regime may be possible when applied to less severely affected feet and the condition may be more benign in female cases.
