RESUMO
BACKGROUND: Clubfoot, presenting as a rigid inward and downward turning of the foot, is one of the most common congenital musculoskeletal anomalies. The aetiology of clubfoot is poorly understood and variants in known clubfoot disease genes account for only a small portion of the heritability. METHODS: Exome sequence data were generated from 1190 non-syndromic clubfoot cases and their family members from multiple ethnicities. Ultra-rare variant burden analysis was performed comparing 857 unrelated clubfoot cases with European ancestry with two independent ethnicity-matched control groups (1043 in-house and 56 885 gnomAD controls). Additional variants in prioritised genes were identified in a larger cohort, including probands with non-European ancestry. Segregation analysis was performed in multiplex families when available. RESULTS: Rare variants in 29 genes were enriched in clubfoot cases, including PITX1 (a known clubfoot disease gene), HOXD12, COL12A1, COL9A3 and LMX1B. In addition, rare variants in posterior HOX genes (HOX9-13) were enriched overall in clubfoot cases. In total, variants in these genes were present in 8.4% (100/1190) of clubfoot cases with both European and non-European ancestry. Among these, 3 are de novo and 22 show variable penetrance, including 4 HOXD12 variants that segregate with clubfoot. CONCLUSION: We report HOXD12 as a novel clubfoot disease gene and demonstrate a phenotypic expansion of known disease genes (myopathy gene COL12A1, Ehlers-Danlos syndrome gene COL9A3 and nail-patella syndrome gene LMX1B) to include isolated clubfoot.

Synaptotagmin-1 (SYT1) plays a pivotal role in regulating presynaptic processes, including neurotransmitter release. SYT1 variants perturb synaptic vesicle endocytosis and exocytosis, resulting in a series of neurodevelopmental disorders defined as Baker-Gordon syndrome. Herein, we report the case of a newborn with dysmorphic facial appearance, severe hypotonia, poor feeding, gastroesophageal reflux, and an inability to eat and breathe, diagnosed with Baker-Gordon syndrome. A retrospective search was performed on a newborn with Baker-Gordon syndrome. Medical charts were reviewed, with focus on the clinical presentation, diagnostic process, and treatment outcomes. Whole-genome high-throughput DNA sequencing was performed to identify genetic variants. Whole-exome sequencing identified the likely pathogenic variant as SYT1 C.551 T > C(p.V184A). Sanger sequencing results indicated that this variant was a de novo mutation in a conservative site located in the C2A domain of the protein. The patient died at 57 days old because of severe feeding and breathing problems. Our findings of a novel lethal variant in the C2A domain of SYT1 in the youngest patient diagnosed infantile Baker-Gordon syndrome who presented with the most severe hypotonia reported to date expands the spectrum of SYT1- associated neurodevelopmental disorders.

Congenital talipes equinovarus (CTEV), also known as clubfoot, is a common musculoskeletal entity that affects one to two per 1000 live births worldwide. Imaging modalities including radiography, US, and MRI have emerged as valuable tools for the diagnosis, treatment, and monitoring of CTEV. The deformity is characterized by midfoot cavus, forefoot adductus, and hindfoot varus and equinus. The Ponseti method of manipulation and serial casting is the standard treatment of CTEV. Radiography shows the anatomy, position, and relationships of the different bones of the foot. US allows accurate assessment of cartilaginous and bony structures, in addition to its inherent advantages such as absence of ionizing radiation exposure. One of the indications for US is to monitor the response to Ponseti method treatment. MRI enables visualization of bones, cartilage, and soft tissues and allows multiplanar evaluation of deformities, providing a comprehensive imaging analysis of CTEV. An integrated approach that combines clinical examination and imaging findings is essential for effective management of CTEV. The authors provide a comprehensive overview of CTEV with a review of imaging modalities to help evaluate CTEV, focusing on radiography, US, and MRI. Using this article as a guide, radiologists involved in the assessment and treatment of CTEV can contribute to the management of the condition. ©RSNA, 2024 Supplemental material is available for this article.

INTRODUCTION: The aim of this study is to evaluate the benefit of cytogenetic testing by amniocentesis after an ultrasound diagnosis of isolated bilateral talipes equinovarus. MATERIAL AND METHODS: This multicenter observational retrospective study includes all prenatally diagnosed cases of isolated bilateral talipes equinovarus in five fetal medicine centers from 2012 through 2021. Ultrasound data, amniocentesis results, biochemical analyses of amniotic fluid and parental blood samples to test neuromuscular diseases, pregnancy outcomes, and postnatal outcomes were collected for each patient. RESULTS: In all, 214 fetuses with isolated bilateral talipes equinovarus were analyzed. A first-degree family history of talipes equinovarus existed in 9.8% (21/214) of our cohort. Amniocentesis was proposed to 86.0% (184/214) and performed in 70.1% (129/184) of cases. Of the 184 karyotypes performed, two (1.6%) were abnormal (one trisomy 21 and one triple X syndrome). Of the 103 microarrays performed, two (1.9%) revealed a pathogenic copy number variation (one with a de novo 18p deletion and one with a de novo 22q11.2 deletion) (DiGeorge syndrome). Neuromuscular diseases (spinal muscular amyotrophy, myasthenia gravis, and Steinert disease) were tested for in 56 fetuses (27.6%); all were negative. Overall, 97.6% (165/169) of fetuses were live-born, and the diagnosis of isolated bilateral talipes equinovarus was confirmed for 98.6% (139/141). Three medical terminations of pregnancy were performed (for the fetuses diagnosed with Down syndrome, DiGeorge syndrome, and the 18p deletion). Telephone calls (at a mean follow-up age of 4.5 years) were made to all parents to collect medium-term and long-term follow-up information, and 70 (33.0%) families were successfully contacted. Two reported a rare genetic disease diagnosed postnatally (one primary microcephaly and one infantile glycine encephalopathy). Parents did not report any noticeably abnormal psychomotor development among the other children during this data collection. CONCLUSIONS: Despite the low rate of pathogenic chromosomal abnormalities diagnosed prenatally after this ultrasound diagnosis, the risk of chromosomal aberration exceeds the risks of amniocentesis. These data may be helpful in prenatal counseling situations.

Schinzel-Giedion syndrome (SGS) is a severe multisystem disorder characterized by distinctive facial features, profound intellectual disability, refractory epilepsy, cortical visual impairment, hearing loss, and various congenital anomalies. SGS is attributed to gain-of-function (GoF) variants in the SETBP1 gene, with reported variants causing canonical SGS located within a 12 bp hotspot region encoding SETBP1 residues aa868-871 (degron). Here, we describe a case of typical SGS caused by a novel heterozygous missense variant, D874V, adjacent to the degron. The female patient was diagnosed in the neonatal period and presented with characteristic facial phenotype (midface retraction, prominent forehead, and low-set ears), bilateral symmetrical talipes equinovarus, overlapping toes, and severe bilateral hydronephrosis accompanied by congenital heart disease, consistent with canonical SGS. This is the first report of a typical SGS caused by a, SETBP1 non-degron missense variant. This case expands the genetic spectrum of SGS and provides new insights into genotype-phenotype correlations.

BACKGROUND: Clubfoot is one of the most common congenital malformations, but it is also one of the most neglected public health problems among less than five-year-old children, mainly in middle- and low-income countries. Approximately 80% of clubfoot cases are found in low- and middle-income countries. In this study setting, no epidemiological studies have been conducted to assess clubfoot deformity. Due to this gap, the study aimed to assess prevalence, and pattern of congenital club foot among less than 5-year-old children. MATERIALS AND METHODS: An institutional-based cross-sectional study was carried out at Black Lion Specialized Hospital at the pediatric orthopedic clinic. The sample size was 261 to determine the prevalence and pattern of congenital clubfoot. Terms like frequency, percentage, and mean were used for data presentation. RESULT: A total of 36,303 pediatric patients visited Black Lion Specialized Hospital during the study period, and clubfoot prevalence was 7.2 per 1000. The largest subclassification of congenital clubfoot was idiopathic clubfoot, which accounted for 6.2 per 1000, whereas syndromic clubfoot was 0.3 per 1000, and neuropathic clubfoot was shared at 0.36 per 1000. Most of the cases in this study were bilateral clubfoot, with males having more dominance. CONCLUSION: In the area under investigation, a significant prevalence of congenital clubfoot was observed, especially among male children. The majority of cases were bilateral, with idiopathic clubfoot being the dominant form.

PURPOSE: Review the literature and describe the complications associated with each of the anterior tibial tendon transfer (ATTT) techniques described. METHODS: A systematic review of the literature was performed with the keywords ''clubfoot'', ''Ponseti'' and ''anterior tibial''. Studies in patients with clubfoot recurrence, who underwent ATTT, whose method of tendon fixation was different from the classical method, were included. RESULTS: Six studies were included in this systematic review, which described multiple techniques for tibialis anterior fixation: bone anchors, interference screws, endobotton, K-wires, transosseous suture, and suture to the plantar fascia. In the papers that described postoperative complications, no major complications were reported, however the samples are generally small. CONCLUSION: Several options have now emerged for tendon fixation in tendon transfers around the foot and ankle, including ATTT for treatment of relapsed clubfoot. To our knowledge this is the first paper that questioned the potential complications associated with the use of these new techniques. Due to the scarcity of published works in favor of other fixation methods, we believe that the traditional method is the optimal one for the transfer of the tendon of the tibialis anterior muscle.

BACKGROUND: The Ponseti method for treating clubfoot consists of initial treatment with serial casting accompanied by achillotenotomy if needed, followed by the maintenance phase including treatment with a foot abduction orthosis (FAO) for at least four years. This study aimed to examine the duration, course, and outcome of orthotic treatment in children with clubfoot. METHODS: 321 children with clubfoot, born between 2015 and 2017, registered in the Swedish Pediatric Orthopedic Quality Register (SPOQ), were included in this prospective cohort study. Data on deformity characteristics and orthotic treatment were extracted. For children with bilateral clubfoot, one foot was included in the analysis. RESULTS: Of the 288 children with isolated clubfoot, 274 children (95.5%) were prescribed an FAO, and 100 children (35%) changed orthosis type before 4 years of age. Of the 33 children with non-isolated clubfoot, 25 children (76%) were prescribed an FAO, and 21 children (64%) changed orthosis type before 4 years of age. 220 children with isolated clubfoot (76%), and 28 children with non-isolated clubfoot (84%) continued orthotic treatment until 4 years of age or longer. Among children with isolated clubfoot, children ending orthotic treatment before 4 years of age (n = 63) had lower Pirani scores at birth compared to children ending orthotic treatment at/after 4 years of age (n = 219) (p = 0.01). It was more common to change orthosis type among children ending orthotic treatment before 4 years of age (p = 0.031). CONCLUSIONS: The majority of children with clubfoot in Sweden are treated with an FAO during the maintenance phase. The proportion of children changing orthosis type was significantly greater and the Pirani score at diagnosis was lower significantly among children ending orthotic treatment before 4 years of age. Long-term follow-up studies are warranted to fully understand how to optimize, and individualize, orthotic treatment with respect to foot involvement and severity of deformity. LEVEL OF EVIDENCE: II.

Even under ideal circumstances, recurrence of infantile clubfoot deformity following the Ponseti method of treatment is to be expected to occur in as many as 20% of patients. When encountered early in childhood, these recurrences are usually amenable to further casting and limited surgery. Creation of a plantigrade foot, however, becomes much more challenging when recurrences present during adolescence and early adulthood. Because of the stiffer nature of these deformities in older patients, the fact that they are often more severe because of varying lengths of neglect, and the often deleterious effects of prior intra-articular surgeries on joint health, a principled approach is recommended for both the assessment of these feet and development of an appropriate treatment plan. In doing so, the surgeon can select the combination of nonsurgical and surgical interventions that allows for as little surgery as possible to create a plantigrade foot while maintaining any motion that is present before treatment. Although no single algorithmic approach can be applied to the variety of deformities and potentially complicating factors that are encountered in treating such patients, an understanding of the utility of preoperative casting, gradual and acute corrective techniques, and the importance of identifying and mitigating deforming forces and tendon imbalance can greatly optimize outcomes.

BACKGROUND: Congenital talipes equinovarus (CTEV) is a relatively common pediatric orthopaedic disorder and a frequent cause of disability in adult populations. The Ponseti method has emerged as the generally preferred for treating children with CTEV. Strict adherence to this technique's basic principles is critical to achieving favorable outcomes. In 2013, our institution decided that every case of pediatric CTEV would be treated by a single dedicated medical team. The present study aimed to compare the treatment outcomes of children with CTEV treated using the Ponseti method in period I (multiple surgeons) versus those in period II (single dedicated team). PATIENTS AND METHODS: We included respectively the children with CTEV treated using the Ponseti method in Geneva University Hospitals' pediatric units from 2007 to 2018. Data on patient demographics, clinical characteristics, and the treatment outcomes were collected. The primary outcome was the number of relapsed feet (treatment failure) after 3 years of follow-up. The 2 periods' outcomes were compared using χ 2 and independent Student t -tests. Run charts were used to report yearly rates of complications, minor and major recurrences, treatment failure, brace noncompliance, and feet that underwent tenotomy. RESULTS: A total of 48 feet (32 patients) and 42 feet (29 patients) in periods I and II were included. The periods showed similar rates for participants' characteristics. The run charts illustrated the overall improvements in treatment outcomes in period II. A total of 8 relapsed feet (5 patients) were reported, all during period I. CONCLUSIONS: Since all the pediatric CTEV patients at our institution began to be treated by a single dedicated medical team, we have observed a decrease in all recurrences and complications and an absence of treatment failure. These results highlight the importance of the continuity of care and strict adherence to the Ponseti method. LEVEL OF EVIDENCE: Level-III Retrospective comparative study.

INTRODUCTION: Constriction band syndrome (CBS) is a congenital limb anomaly frequently associated with clubfoot. Clubfeet in CBS patients may be associated with peroneal nerve dysfunction in the involved lower extremity; however, the etiology of this neuromuscular dysfunction is not clear. We sought to characterize the distribution of constriction bands on lower extremities with clubfoot and determine if neuromuscular deficit (NMD), defined here as having absent ankle dorsiflexion, was associated with ipsilateral proximal bands. Our secondary aim was to compare the treatment and outcomes of clubfeet with NMD to those without NMD. METHODS: We performed a retrospective review of all patients with CBS and clubfoot presenting to our facility between January 1, 1998 and December 31, 2018. Treatment with the Ponseti method, at least 1 year of follow-up at this facility, and a detailed physical exam describing lower extremity neuromuscular function and the presence and location of constriction bands were required for inclusion in the study cohort. RESULTS: Twenty children with 26 clubfeet were included. Forty-six percent (12/26) of the clubfeet had NMD. Clubfeet with and without NMD had ipsilateral thigh or leg constriction bands at similar rates [42% (5/12) vs. 43% (6/14), P =0.106], and the majority (7/12) of clubfeet with NMD did not have an ipsilateral thigh or leg band. While children with an NMD clubfoot tended toward more casts, relapses, and surgical procedures, these differences did not reach statistical significance. The use of a daytime AFO beyond age four was higher in the NMD clubfeet [58% (7/12) vs. 14% (2/14), P =0.04]. CONCLUSION: Clubfeet with neuromuscular deficits may occur in the absence of proximal ipsilateral constriction bands, suggesting they may be caused by mechanisms other than direct damage from visible constriction bands to underlying nerves. They can also coexist with arthrogrypotic conditions. Clubfeet with an NMD tended toward more casts, relapses, and surgeries than those without NMD, but these differences did not reach statistical significance. These patients often elect long-term use of a daytime AFO.

INTRODUCTION: The Ponseti serial casting method is the method of choice in treating children with congenital clubfeet. The arthrogrypotic clubfoot has traditionally been considered challenging to treat, with higher rates of recurrence and the need for more corrective surgeries. However, initial reports have found promising results in using the Ponseti method to treat arthrogrypotic feet. This study aims to compare the outcomes of idiopathic versus arthrogrypotic clubfeet following initial treatment with the Ponseti serial casting method. METHODS: A retrospective review of medical records from a single institution was conducted. Data was collected from children ages 0 to 18 with idiopathic or arthrogrypotic clubfoot treated from 2002 to 2022 with Ponseti-style serial casting with a minimum 2-year follow-up. Recurrence was defined as the need for additional casting or subsequent surgeries following initial correction. Data was collected on relevant patient demographics, previous treatment, casting records, Achilles tenotomies, and surgical treatments. RESULTS: A total of 352 patients (546 feet) met inclusion criteria. In all, 334 idiopathic and 18 arthrogrypotic patients were analyzed with an average follow-up duration of 3.4 and 4.2 years, respectively. Twelve patients had distal arthrogryposis, and 6 had amyoplasia. In all, 93.4% of idiopathic and 72.2% of arthrogrypotic patients successfully achieved correction with Ponseti casting and Achilles tenotomy. Recurrence rates were significantly higher in the arthrogrypotic group at 83.3% compared with 44.6% in the idiopathic group ( P =0.001). A posterior or posterior medial release was performed in 35.0% of idiopathic and 66.7% arthrogrypotic feet. CONCLUSIONS: We report the largest series of arthrogrypotic clubfeet treated by Ponseti casting to the best of our knowledge. In contrast to earlier reports, our investigation underscores that while the Ponseti method may be able to secure initial correction in arthrogrypotic clubfeet, on average, at a 3-year follow-up, the prognosis is less favorable. These patients exhibit higher recurrence and often require operative treatment. Notably, a posterior medial release may eventually be needed in up to 6 of 10 patients. LEVEL OF EVIDENCE: Level III-therapeutic studies-investigating the results of treatment.

BACKGROUND: Congenital talipes equinovarus, also known as "clubfoot," is a common congenital deformity. While reported relapse rates vary widely, relapse continues to be a common problem faced in the treatment of this condition. The objective of this study is to assess relationships between demographic/socioeconomic factors, follow-up, and rates of relapse in our population of clubfoot patients. METHODS: Retrospective chart review was conducted for patients undergoing treatment for idiopathic clubfoot from February 2012 to December 2022 at a tertiary children's hospital. Records were analyzed for follow-up adherence and recurrence in the Ponseti method, in addition to patient demographic and socioeconomic factors. Statistical analysis was performed to evaluate associations between recurrence, missed clinical visits, and demographic/socioeconomic factors of interest. RESULTS: Ninety-five patients were included in the study [74.7% male (N=71) and 25.2% female (N=24)]. A total of 64.2% (N=61) of patients developed recurrence during their treatment. Recurrence rates differed significantly by reported bracing noncompliance >1 month (35/46 vs. 26/49, P =0.019), having missed 1 or more clinical visits (38/61 vs. 8/34, P < 0.001), Medicaid or equivalent insurance type (41/56 vs. 20/39, P =0.028), non-white race (47/66 vs. 14/29, P =0.032, higher Social Deprivation Index score (56.13 vs. 41.06, P =0.019). Significant variables were analyzed using a multivariate logistic regression analysis (MVLR). After MVLR, having 1 or more missed clinical visits (OR 4.462, 95% CI: 1.549-12.856) remained significantly associated with increased rates of recurrence. Primary language preference and distance to the hospital were not associated with recurrence. CONCLUSIONS: Higher SDI scores, non-white race, Medicaid insurance, and missed clinical follow-up visits were all associated with increased rates of recurrence for clubfoot patients. Using an MVLR model, missed clinical follow-up visits remained independently associated with increased recurrence rates. LEVEL OF EVIDENCE: Level 2-retrospective, prognostic study.

BACKGROUND: Talipesequinovarus is a congenital ankle/foot malformation that commonly affects newborns. In its treatment using the Ponseti method, an Achilles tenotomy is frequently needed to correct residual equinus deformity. Percutaneous (PC) tenotomy is the most commonly used technique and needs to be thoroughly evaluated. The question we needed to answer was: "Does PC Achilles tenotomy result in complete tendon sectioning"? METHODS: This clinical study included 56 idiopathic clubfeet in 36 patients who presented during the first 6 months of life and were treated with Ponseti manipulation and casting followed by PC Achilles tenotomy. PC tenotomy was done under general anesthesia, and Thompson's calf squeeze test was performed intraoperatively just after tenotomy. In case of a negative test (ie, ankle plantar flexion with calf squeeze), the percutaneous incision was extended to assess the cause of the negative test. RESULTS: Forty-nine feet (87.5%) had a complete tenotomy, as evidenced by a positive Thompson's calf squeeze test. While 7 feet (12.5%) showed a negative test, and therefore the percutaneous incision was extended and all were found to have an incompletely divided Achilles tendon. The tendons were then completely divided, after which Thompson's test became positive in all. CONCLUSION: Percutaneous Achilles tenotomy is a reliable procedure, but was found to result in incomplete tendon sectioning in 12.5% of cases, affecting the range of ankle dorsiflexion. Thompson's squeeze test is reliable in picking up cases of incomplete tenotomy after the PC technique, and in these cases the incision should be extended for complete sectioning. LEVEL OF EVIDENCE: Level I.

BACKGROUND: As the incidence of childhood obesity continues to rise, so too does the number of obese children who undergo foot surgery. As the childhood obesity epidemic rolls on, pediatric orthopaedic surgeons will encounter obese patients with even greater frequency. Therefore, a comprehensive understanding of the risks associated with obesity is valuable to maximize patient safety. The purpose of this study is to retrospectively evaluate the relationship between obesity and postoperative outcomes in patients undergoing pediatric foot surgery across multiple institutions using a large national database. METHODS: Pediatric patients who had undergone foot surgery were retrospectively identified using the American College of Surgeons 2012-2017 Pediatric National Surgical Quality Improvement (ACS-NSQIP-Pediatric) database by cross-referencing reconstructive foot-specific CPT codes with ICD-9/ICD-10 diagnosis codes. Center for Disease Control BMI-to-age growth charts were used to stratify patients into normal-weight and obese cohorts. Univariate and multivariate analyses were performed to describe and assess outcomes in obese compared with normal-weight patients. RESULTS: Of the 3924 patients identified, 1063 (27.1%) were obese. Compared with normal-weight patients, obese patients were more often male (64.7% vs. 58.7%; P =0.001) and taller (56.3 vs. 51.3 inches; P <0.001). Obese patients had significantly higher rates of overall postoperative complications (3.01% vs. 1.32%; P =0.001) and wound dehiscence (1.41% vs. 0.59%; P =0.039). Multivariate analysis found that obesity was an independent predictor of both wound dehiscence [adjusted odds ratio (OR)=2.16; 95% CI=1.05-4.50; P =0.037] and surgical site infection (adjusted OR=3.03; 95% CI=1.39-6.61; P =0.005). Subgroup analysis of patients undergoing clubfoot capsular release procedures identified that obese patients had a higher rate of wound dehiscence (3.39% vs. 0.51%; P =0.039) compared with normal-weight patients. In multivariate analysis, obesity was an independent predictor of dehiscence (adjusted OR=5.71; 95% CI=1.46-22.31; P =0.012) in this procedure group. There were no differences in complication rates between obese and normal-weight patients in a subgroup analysis of tarsal coalition procedures or clubfoot tibialis anterior tendon transfer procedures. CONCLUSION: Obese children undergoing foot surgery had higher overall complication rates, wound complications, and surgical site infections compared with children of normal weight. As the incidence of childhood obesity continues to rise, this information may be useful in assessing and discussing surgical risks with patients and their families. LEVEL OF EVIDENCE: III.

PURPOSE: The purpose of this study is to compare the results of the Oxford Ankle and Foot Questionnaire (OxAFQ) in children with clubfoot in Canada and India to assess its ability to predict outcomes and capture patient experiences in different cultural contexts. METHODS: This is a retrospective study of children with clubfoot in India and Canada who completed the OxAFQ. Statistical analyses were implemented on registry-collected data to test for independent predictors of poor outcomes and compare scores between countries, among children and their parents, and in Canada where relapse data was collected and the effect of a relapse on scores. RESULTS: A total of 361 children were included. The mean Indian OxAFQ scores were higher (p < 0.001) in all domains. Pirani score, tenotomy, laterality, and age at presentation were found to be predictive of outcomes between the sites (p < 0.05). OxAFQ scores decreased after relapse for children in Canada (p < 0.05). Canadian children were found to generally have lower OxAFQ scores in all domains compared to their parents (n = 95; Z = -3.178, -3.493, -3.353, and -3.635 for physical, school and play, emotion, and footwear, respectively; p < 0.001). Indian parents and children showed no significant differences in their scores. CONCLUSIONS: A difference was observed in scores between both sites, suggesting there may be differences in how these populations assess personal health outcomes. These findings support the need for cultural validity of patient-reported outcome measures.

PURPOSE: The aims of the study were to document the outcomes of percutaneous Achilles tenotomy (pAT) performed in older children with clubfoot, by assessing the clinical, functional and ultrasonographic evidence of Achilles tendon regeneration. METHODS: A retrospective case series of older children with clubfoot treated between August 2011 and July 2020 was studied. Clinical assessment of ankle range of motion and calf strength, functional assessment of triceps surae muscle endurance by single leg heel-rise test, and ultrasonographic assessment of Achilles tendon echotexture and dimensions to assess tendon regeneration were performed. RESULTS: Percutaneous Achilles tenotomy was performed on 31 children (48 clubfeet) at a mean age of 5.24 ± 2.14 years (1-10.2 years). At a mean follow-up of 4.86 ± 1.97 years, all children demonstrated normal calf strength with mean dorsiflexion range of 13.64° (0-25°) and mean plantarflexion range of 37.95° (10-40°). The heel-rise endurance test was completed by 27 children with mean 25.85 heel rises/minute (range 17-30) and mean height of heel rise of 6.29 cm (range 4-10 cm). Normal fibrillar tendinous echotexture with homogenous echogenicity was seen on ultrasonography in 41 feet (85.4%) with mean tendon width of 9.7 mm (3.3-16 mm) and thickness of 5.1 mm (1.8-15 mm), comparable with unaffected feet. CONCLUSIONS: Clinical, functional and ultrasonographic parameters unequivocally demonstrate complete regeneration of the Achilles tendon, when pAT is performed in older children with delayed-presenting idiopathic clubfoot treated using Ponseti principles.

PURPOSE: Despite the existence of guidelines for screening for developmental dysplasia of the hip (DDH), there remains controversy regarding the need for routine ultrasound screening for DDH in patients with clubfoot due to an unclear correlation between the two conditions. The purpose of this study is to determine whether ultrasound screening for DDH in this population improved the diagnostic accuracy of DDH over standard assessment for patient risk factors and physical exam. METHODS: This is a retrospective cross-sectional review of infants diagnosed with idiopathic clubfoot who underwent hip ultrasounds to assess for DDH as identified by keyword search in an institutional radiological database at a tertiary care paediatric hospital. Patient demographics, risk factors for DDH, physical exam findings, and ultrasound results were recorded. RESULTS: Of the 120 patients who met the inclusion criteria between 2003 and 2018, 8 had hip dysplasia confirmed on ultrasound (6.7%). All these patients either had known risk factors for hip dysplasia or had an abnormal physical exam finding suggestive of hip instability or dislocation as performed by an orthopaedic surgeon on their initial consultation. CONCLUSION: A detailed history to determine risk factors and a thorough physical exam are adequate to determine the need for hip ultrasound in infants with idiopathic clubfoot. Routine ultrasound screening of all patients with clubfoot is likely unnecessary and may pose a significant burden on the health care system.

PURPOSE: Selective tibial neurotomy (STN) is a surgical procedure for treating spastic equinovarus foot. Hyperselective neurectomy (HSN) of tibial nerve is a modified STN procedure, which was rarely discussed. This study aimed to describe the branching patterns of the tibial nerve and propose an optimal surgical incision of HSN for treatment of spastic equinovarus foot. METHODS: Sixteen lower limbs were dissected to determine the various branching patterns of the tibial nerve and categorized according to these branching patterns. The mean distances from the nerve entry points to the tip of femur's medial epicondyle were measured, as well as their percentage to the overall length of the leg. The surgical incision was designed according to the range of these nerve entry points. RESULTS: The tibial nerve sent out proximal and distal motor branches based on their position relative to the soleus muscle's tendinous arch. For proximal motor branches, the branches innervating the medial gastrocnemius, lateral gastrocnemius and proximal soleus were categorized into types I (9/16), II (5/16) and III (2/16). Measurements from the medial epicondyle to the nerve entry points into the medial gastrocnemius, lateral gastrocnemius and proximal soleus ranged from 14 to 33 mm (4-9% of leg length), 22-45 mm (6-12%) and 35-81 mm (10-22%), respectively. Distal motor branches including the distal soleus, posterior tibialis, flexor digitorum longus and flexor hallucis longus, were classified as types A (8/14), B (4/14) and C (2/14), with the distances from their respective terminal points to the medial epicondyle were 67-137 mm (19-39%), 74-125 mm (20-35%), 116-243 mm (33-69%) and 125-272 mm (35-77%). CONCLUSIONS: The motor branches of tibial nerve were classified into two groups and each subdivided into three types. Detailed location parameters may serve as an anatomical basis for designing incision of HSN.

Noninvasive techniques are gold standard to redress Severe Neuromuscular Foot Deformity (SNFD). However, simple talectomy may be considered to obtain a stable, plantigrade, pain-free foot. We present a 10-year follow-up accessing radiological correction rates, functional outcomes, complications, and patient satisfaction. This retrospective case series evaluated talectomies in 2012 to 2022. Simple talectomy was combined with Steinman pin fixation of calcaneus to tibia for approximately 6 weeks. Diagnoses primarily included arthrogryposis multiplex congenita and cerebral palsy. Indications were pain, wounds/pressure marks, severe rigidity, and residual/recurrent deformity. The primary outcome was radiological correction. Tibiotalar angle (TiTa) and tibiocalcaneal angle (TiCa) were measured on mediolateral projections. Secondary outcomes were functional scores of pain/deformity graded as good, fair or poor. Furthermore, validated patient-reported outcome measures, that is, EQ-5D-5L and the Scoliosis Research Society-30 Questionnaire (2 items) assessed health-related quality of life and patient satisfaction. Nineteen talectomies in 11 patients were analyzed. Mean follow-up was 62 months (range 9-112 months). Mean TiTa was 137° (95%CI 128;146). TiCa improved significantly: Mean difference -24° (95%CI -44;-5, p = .02). All feet became plantigrade and pain-free with no skin issues. Functional outcomes were graded as 9/19 good, 10/19 fair and 0/19 poor. Parents/primary caregivers were mainly satisfied. Perceived health was 54 (95%CI 34;75) out of 100 on a visual analogue scale, emphasizing complex medical conditions. In conclusion, simple talectomy is a suitable salvage procedure for SNFD.
