Outcomes of clubfoot conservative treatment using the Ponseti technique in an academic hospital in Saudi Arabia

Objectives: Congenital talipes equinovarus (CTEV), commonly known as clubfoot, affects 1–4/1000 births, predominantly males. Without intervention, children face mobility limitations and deformities. Conservative treatment, particularly the Ponseti technique, which boasts a success rate exceeding 90%, is favored despite potential complications. Methods: This study aimed to assess the efficacy of the Ponseti technique through a retrospective analysis of idiopathic CTEV cases. Data on pre- and post-treatment Pirani scores were analyzed across variables including age, sex, number of casts, Achilles tenotomy, surgical intervention, and complications. Participants were categorized based on treatment outcomes to identify contributing factors. Results: Among 42 participants (69 feet), 62% were male, presenting at an average age of 9 weeks and receiving an average of 5.26 casts per patient. Pre-treatment Pirani scores averaged 4.52, significantly decreasing to 0.88 post-treatment. Feet managed without surgery demonstrated greater improvement in Pirani scores (mean change 3.888) compared to those requiring surgery (mean change 2.364), a statistically significant difference (P < 0.001). Acceptable outcomes were observed in 84.06% of feet. Percutaneous Achilles tenotomy was performed in 84% of cases. Surgical intervention was necessary in 15.94% of feet. Casting complications occurred in 14.49% of feet. Conclusion: This study confirms the Ponseti technique’s effectiveness in managing idiopathic CTEV, emphasizing early detection and initiation of conservative treatment. The early findings establish the Ponseti technique as the preferred initial approach for CTEV management.

Usefulness and accessibility of information on the treatment of children with congenital clubfoot: results of a survey of parents

BACKGROUND: Treatment of congenital clubfoot remains controversial from both specialists and parents regarding the details of its practical application, individual effectiveness, and follow-up, rehabilitation treatment, prevention, and treatment of relapses. The assessment of parental attitudes using an online survey optimizes doctor–patient interaction. Information available to parents regarding the diagnosis and treatment of children with congenital clubfoot is lacking. AIM: This study aimed to assess the usefulness and accessibility of information for parents about the treatment of children with congenital clubfoot. MATERIALS AND METHODS: To assess the usefulness and accessibility of information about the treatment of congenital clubfoot, a survey of the patients’ parents was conducted using an electronic fillable form proposed for anonymous completion in a thematic group dedicated to the treatment of congenital clubfoot on the social network “VKontakte”; the study included 5500 participants at the time of the survey (2 weeks), with 328 responses received. RESULTS: Most parents noted a lack of information regarding clubfoot treatment before it actually began. The preferred source of information was Internet resources (i.e., websites of medical institutions and social networks). Achilles tenotomy and wearing braces raised the most questions, requiring additional information from both doctors and alternative sources. The possibility of errors and complications in wearing braces caused the greatest concern among parents, as well as possible relapses and the correctness of prescriptions during the rehabilitation treatment. Online parent communities and physician blogs are considered significant information sources. Most parents prefer to expand information about congenital clubfoot on the Internet, including social networks and popular resources. CONCLUSIONS: Analysis of the results of an anonymous survey of parents of children with congenital clubfoot showed a significant demand for high-quality, accessible information regarding the diagnosis, treatment, and rehabilitation of children with congenital clubfoot. Significant interest in the information provided by social media and other Internet resources determines the need for competent representatives of the professional community to participate in this process.

Dual and opposing role of retinoic acid receptor signaling in mesenchymal stem cells for tendon ossification in mice.

Heterotopic ossification is abnormal bone formation in soft tissues that occurs primarily after injury and major surgery. This condition often causes local pain and limits joint motion in the affected limb. Currently, there is no effective treatment or prophylaxis for this condition other than surgical removal of the lesion. Recent studies suggest that retinoic acid receptor (RAR) agonists are effective in suppressing heterotopic ossification in patients with Fibrodysplasia Ossificans Progressiva, a congenital disorder characterized by progressive ossification of soft tissue, by suppressing the aberrant differentiation of mesenchymal stem cells in muscle. In this study, we aimed to elucidate the potential use of RAR agonists in suppressing injury-induced ectopic tendon ossification using a mouse Achilles tenotomy model. Contrary to our initial hypothesis, administration of RAR agonists throughout the experimental period (5 weeks) accelerated ectopic tendon ossification in our model. Of note, in vitro differentiation experiments using tendon-derived mesenchymal stem cells revealed that RAR agonists play opposing roles in osteogenic and chondrogenic differentiation, promoting the former and suppressing the latter. Indeed, we found that RAR agonists suppressed tendon ossification when administered before cartilage nodule formation, but promoted it when administered after. These results suggest that RAR agonists have a dual and opposing effect on tendon ectopic ossification, depending on the duration and timing of their administration. Our data may provide a basis for further investigation of the potential use of RAR agonists in the treatment of injury-induced heterotopic ossification.

Estrogen Deficiency Exacerbates Traumatic Heterotopic Ossification in Mice.

Traumatic heterotopic ossification (HO) is a devastating sequela of orthopedic surgeries and traumatic injuries; however, few studies have explored the effects of the estrogen-deficient state on HO formation. In the present study, we investigated the impact of estrogen deficiency on ectopic cartilage and bone formation in tendon after Achilles tenotomy in an ovariectomized mouse model. A total of 45 female C57BL/6 mice were randomly divided into three groups: sham-operated (control), estrogen depletion by ovariectomy (OVX) and OVX with 17β-estradiol supplementation (OVX + E2), with 15 animals in each group. Three weeks after OVX, all mice were subjected to an Achilles tenotomy using a posterior midpoint approach to induce HO. At 1, 3 and 9 weeks after tenotomy, the left hind limbs were harvested for histology, immunohistochemistry and immunofluorescence evaluations. The volume of ectopic bone was assessed by micro-CT. Mice in the OVX group formed more ectopic cartilage 3 weeks after tenotomy, as well as ectopic bone 9 weeks after tenotomy, compared to the control group. Estrogen deficiency resulted in more severe inflammatory infiltration at the injury sites 1 week after tenotomy, involving the recruitment of more macrophages and mast cells, as well as increasing the expressions of pro-inflammatory mediators, including IL-1β, IL-6, and TNF-α. Moreover, the local TGF-β/SMAD signaling pathway was dysregulated after OVX, which manifested as upregulated expressions of TGF-β and pSMAD2/3. E2 supplementation protected against OVX-induced HO deterioration, inhibited inflammatory infiltration, and downregulated the TGF-β/SMAD signaling pathway. Estrogen deficiency exacerbated HO formation in the Achilles tenotomy model. These findings might be attributable to the disturbance of the inflammatory response and the activation of TGF-β/SMAD signaling at the injury sites during the early stages of HO development.

Pitfalls and complications in the treatment of clubfoot by the Ponseti method: A literature review

BACKGROUND: At every step of clubfoot treatment using the Ponseti method, pitfalls leading to complications, both minor and potentially dangerous, may occur. Any doctor involved in the treatment of clubfoot may encounter similar difficulties in their practice; however, publications devoted to this problem are limited, and in some cases, experts cannot reach a consensus regarding the interpretation of actions that entail undesirable consequences. AIM: This study aimed to analyze pitfalls and complications associated with the Ponseti method for the treatment of clubfoot using modern literature data. MATERIALS AND METHODS: Articles were searched for in PubMed, Science Direct, Google Scholar, and eLibrary databases using the following keywords: idiopathic clubfoot, Ponseti method, serial casting, bracing, Achilles tenotomy, pitfalls, and complications. The search was performed without language restrictions. Most of the studies included were published no more than 10 years ago. RESULTS: Current literature data present on the pitfalls and complications encountered in the treatment of clubfoot using the Ponseti method. The review also covered associated complications and unfavorable prognostic factors. The restrictive measures during the COVID-19 pandemic have affected the treatment of clubfoot. CONCLUSIONS: Analysis of the causes of pitfalls and complications and control of unfavorable prognostic factors will help reduce complications of clubfoot treatment using the Ponseti method and optimize orthopedic care for children.

Delayed Achilles Tendon Rupture at 17 Years of Age After Treatment of Clubfoot with Ponseti Method: A Case Report.

Traumatic pediatric Achilles ruptures are rare, and few cases have been reported among patients with a history of Achilles tenotomy. A 17-year-old boy with a history of Achilles tenotomies for congenital clubfoot as an infant presented with acute midsubstance Achilles tendon rupture of the right leg. The gastrocnemius fascia was dissected to allow for approximation of the ruptured Achilles tendon segments. Furthermore, the plantaris tendon was harvested and sutured around the Achilles tendon-rupture site to improve strength. Patients with a history of clubfoot and chronic Achilles tendon pain should be alerted to the risk of Achilles tendon rupture.

The Efficacy of General Anesthesia with Sevoflurane for Pain Management in Neonates and Infants with Idiopathic Clubfoot Treated with Ponseti Technique and Percutaneous Achilles Tenotomy

Background: Idiopathic clubfoot deformity is a relatively common congenital pediatric foot deformity. A percutaneous Achilles tenotomy (PAT) is required to correct the equinus deformity as it is the most resistant component of clubfoot deformity. Although this procedure is mainly performed with local anesthesia, performing this procedure with general anesthesia has significant advantages. Aims: The purpose of this study was to compare the safety and efficacy of post-procedural pain management of PAT in the treatment of clubfoot with the Ponseti method when performed in a clinic setting with local anesthetic or under general anesthesia Methods: This is a multicentric prospective observational evaluation on children less than one year of age with idiopathic clubfoot whom referred for Ponseti casting and PAT. This procedure was done in the control group with local anesthesia and in the intervention group with Sevoflurane mask 8% (MAC 2) and maintenance of anesthesia with Sevoflurane mask 4% (N2O/O2, 50%). The neonatal infant pain scale (NIPS), the amount of milk, and mood changes were evaluated as a criterion to measure the pain level. Results: NIPS score in the intervention group was significantly lower than the control group. Children in the intervention group consume significantly more milk than the control group. Furthermore, 76% of children in the intervention group were classified as "calm," 24% as "relatively restless," and no child was classified as "severely restless." While in the control group, 54% of children were classified as "severely restless," and the remaining 46% as "relatively restless." Conclusion: Our result showed that using general anesthesia to perform achillotomy in the treatment of clubfoot in children could be associated with less pain in these patients and without significant complications.

Early Radiographic Characteristics of the Lateral Talocalcaneal Angle and its Predictive Significance for Relapse in Patients With Idiopathic Clubfoot Treated With the Ponseti Method

In order to evaluate the early radiographic characteristics of the lateral talocalcaneal (L-TC) angle in patients with idiopathic clubfoot (ICF) and to investigate its prognostic significance for relapse after initial treatment with the Ponseti method. We retrospectively included 151 patients (96 males and 55 females; 227 feet) with ICF treated at our Institution between January 2005 and December 2014. The age at initial treatment was less than 6 months, and radiographs were obtained within 3 months of the Achilles tenotomy (mean age: 2.3 months; range: 0.77-6.8). All patients were followed up for at least 7 years (range, 7-18). The participants' feet were classified into three groups: relapsed (Group A), not relapsed (Group B), and normal foot groups which consisted of healthy feet in patients with unilateral ICF (Group C). All angle measurements were expressed in degrees. Forty-seven ICF feet in 33 patients relapsed, while 180 feet in 118 patients did not, and the age at relapse was 5.92±1.91 years. Seventy-five normal feet were included in Group C. The average L-TC angle in Group A and B patients was 33.57°±12.05° and 39.37°±12.55°, respectively, while Group C was 49.61°±9.11°. A significant difference was found among the three groups of patients (F=31.48, P<0.001). The L-TC angle cut-off value below which a recurrence could be predicted was 36.1° (sensitivity, 74.47%). The L-TC angle of ICF patients treated using the Ponseti method were reduced compared to normal feet. An L-TC angle of <36.1° has relative value in predicting ICF relapse. LEVEL OF EVIDENCE: III.

Suppression of TNF-α activity by immobilization rescues Mkx expression and attenuates tendon ossification in a mouse Achilles tenotomy model.

Traumatic heterotopic ossification is a condition in which extraskeletal bone formation occurs in soft tissues after injury. It most commonly occurs in patients who had major orthopedic surgery and in those with severe extremity injuries. The lesion causes local pain and can impair motor function of the affected limb, but there is currently no established prophylaxis or treatment for this condition. In this study, we show that immobilization at an early stage of the inflammatory response after injury can attenuate ossification formation in a murine Achilles tenotomy model. Gene expression analysis revealed a decrease in the expression of Tnf and an increase in the expression of Mkx, which encodes one of the master regulators of tendon differentiation, Mohawk. Notably, we found that TNF-α suppressed the expression of Mkx transcripts and accelerated the osteogenic differentiation of tendon-derived mesenchymal stem cells (MSCs), suggesting that TNF-α acts as a negative regulator of Mkx transcription. Consistent with these findings, pharmaceutical inhibition of TNF-α increased the expression of Mkx transcripts and suppressed bone formation in this mouse model. These findings reveal the previously unrecognized involvement of TNF-α in regulating tendon MSC fate through suppression of Mkx expression and suggest that TNF-α is a potential target for preventing traumatic heterotopic ossification.

Comparative Study of Acute Stress in Infants Undergoing Percutaneous Achilles Tenotomy for Clubfoot vs. Peripheral Line Placement.

Percutaneous tenotomy of the Achilles tendon is a procedure that is part of the Ponseti method for clubfoot correction. The need to apply general anesthesia or sedation for this procedure is controversial. The objective of this study is to compare the acute stress generated in infants by percutaneous Achilles tenotomy under local anesthesia vs. peripheral line placement. This cross-sectional study compares the discomfort experienced by 85 infants undergoing percutaneous Achilles tenotomy with local anesthesia with that experienced by 39 infants undergoing peripheral line placement. The following parameters were determined: the duration of the procedure, crying time, average crying intensity, and maximum crying intensity. Other data recorded included the infant's age and complications arising during the procedure. The mean ages of these patients were 1.95 and 2.18 months, respectively. The following data were obtained: the mean duration of the procedure for Group A was 8.13 s and for Group B it was 127.43 s; the mean duration of crying for Group A was 84.24 s and for Group B it was 195.82 s; the mean intensity of crying for Group A was 88.99 dB and for Group B it was 100.98 dB; and the maximum crying intensity for Group A was 96.56 dB and for Group B it was 107.76 dB. Percutaneous Achilles tenotomy can be safely performed as an outpatient procedure, under local anesthesia. This method generates less discomfort than peripheral line placement.

Ultrasonic Evaluation of the Achilles Tendon in Patients Treated for Congenital Clubfoot: Comparison between Patients Treated with Plaster Alone, Achilles Tenotomy, and Z-Plasty Lengthening.

Clubfoot is a common congenital deformity. The Ponseti technique, involving early corrective manipulations followed by applying long leg casts and Achilles tenotomy, is widely accepted as the preferred treatment. Rapid tendon healing after surgery has been documented, but the aspect regarding long-term tendon structure and properties is not known. Three cases of Achilles tendon rupture in adolescents previously treated for clubfoot have been described in the literature. As rupture is a rare event in this age group, a possible correlation with previous surgery has been hypothesized. The primary aim of the study was to compare the ultrasound findings of the Achilles tendon in patients treated for clubfoot, between patients treated with casting alone and with patients who underwent surgery (percutaneous tenotomy or Z-plasty lengthening). There were 22 asymptomatic patients (34 feet) with a median age of 12 years, previously treated for clubfoot, that were recruited for this study; the patients underwent an Achilles tendon ultrasound examination during a follow-up outpatient visit. A greater thickness and increased number of structural alterations with the presence of hypoechoic areas of the operated tendons compared with those treated with plaster alone were observed (p-value: 0.0498 and <0.001, respectively). These ultrasound findings were indicative of tendon suffering, as seen in tendinopathies. The presence of ultrasound alterations in asymptomatic patients operated on for clubfoot requires careful control of the extrinsic factors of tendinopathy in order to reduce the risk of subcutaneous rupture.

Trends in Medicare Reimbursement for Common Pediatric Orthopedic Procedures: From 2000 to 2022.

Objective We aimed to evaluate trends in government monetary reimbursement (Medicare) for 10 of the most commonly performed pediatric orthopedic procedures from 2000 to 2020. Methods Utilizing the Centers for Medicare and Medicaid Services website, we collected data for 10 of the most commonly performed pediatric orthopedic surgical procedures and their variations. The reimbursement data for each procedure was taken from the Current Procedural Terminology (CPT) code, which was collected from the Physician Fee Schedule Look-Up Tool from the Centers for Medicare and Medicaid Services (Baltimore County, MD). The reimbursement values were adjusted for inflation to the 2022 US dollar (USD) using the changes to the Consumer Price Index. The compound annual growth rates (CAGRs) and total percentage changes in reimbursement were calculated for all the procedures and put into relative value units. Results Reimbursement for 20 of the 22 total procedures decreased by 32.65% from 2000 to 2022 after adjusting for inflation. Achilles tenotomy with local anesthesia saw the greatest decrease (-54.38%), whereas the procedure revision of spinal fusion saw the highest increase (26.00%) in mean adjusted reimbursement during this study period. Adjusted reimbursement decreased by an average of 2.08% on a yearly basis. Conclusion This study is the first to take an in-depth view and evaluate trends in procedural Medicare reimbursement for pediatric orthopedic surgery. When adjusted for inflation, Medicare reimbursement for 20 of 22 included procedures has steadily decreased from 2000 to 2022. There needs to be an increased awareness and consideration of these trends as they will be important for policymakers, hospitals, and surgeons to ensure continued access to meaningful surgical pediatric orthopedic care in the United States.

MANAGEMENT OF CONGENITAL TALIPES EQUINOVARUS WITH PONSETI TECHNIQUE IN CHILDREN UNDER 2 YEARS OF AGE

ABSTRACT: BACKGROUND AND OBJECTIVES: CTEV is a complex congenital deformity of the foot and occurs due to the confluence of genetic &amp; environmental factors. If it is not treated promptly and accordingly, it limits patient mobility and results in a painful foot. In most cases, it is treated conservatively using the Ponseti technique. This method was developed by a Japanese orthopedic surgeon Ignatio Ponseti who successfully treated CTEV in infants without extensive surgery. It is a manipulative technique with percutaneous release of tendoachilles that allows the ankle to obtain correction. This study was conducted to assess the functional outcomes of CTEV management by Ponseti method. METHODS: Ethical approval was obtained from the Ethical Review Board Of Services Hospital Lahore. This descriptive study was conducted at the department of orthopedic surgery from December 2018 to December 2020. A total number of 120 patients having CTEV deformity of the foot, aged less than 2 years, were included in the study. From these, 70 children had bilateral foot involvement. It was treated with 5-7 casts with each cast applied for 07 days according to the Ponseti method. In the final cast, a percutaneous Achilles Tenotomy was performed, where the deformity was restricted to 10 degrees from the neutral. After completion of casts, each patient was braced with Foot Abduction Brace. RESULTS: We used Pirani Score for pre- and post-operative assessment of correction of deformity via Ponseti method. There were 91% excellent results achieved through this method, whilst 6% of patients had good results and 3% had poor results. CONCLUSION: Ponseti technique has got good functional &amp; cosmetic results. It is economical and easy to apply. KEY WORDS: Club foot, Pirani Shafique score, Ponseti technique, CTEV

Outcomes of Ponseti Method for the Treatment of Clubfeet in Children With Arthrogryposis.

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. 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. 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. 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.

Reliability of Percutaneous Achilles Tenotomy in the Treatment of Idiopathic Clubfoot.

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"? 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. 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. 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 I.

Roles of Plasminogen Activator Inhibitor-1 in Heterotopic Ossification Induced by Achilles Tenotomy in Thermal Injured Mice.

Heterotopic ossification (HO) is the process by which ectopic bone forms at an extraskeletal site. Inflammatory conditions induce plasminogen activator inhibitor 1 (PAI-1), an inhibitor of fibrinolysis, which regulates osteogenesis. In the present study, we investigated the roles of PAI-1 in the pathophysiology of HO induced by trauma/burn treatment using PAI-1-deficient mice. PAI-1 deficiency significantly promoted HO and increased the number of alkaline phosphatase (ALP)-positive cells in Achilles tendons after trauma/burn treatment. The mRNA levels of inflammation markers were elevated in Achilles tendons of both wild-type and PAI-1-deficient mice after trauma/burn treatment and PAI-1 mRNA levels were elevated in Achilles tendons of wild-type mice. PAI-1 deficiency significantly up-regulated the expression of Runx2, Osterix, and type 1 collagen in Achilles tendons 9weeks after trauma/burn treatment in mice. In in vitro experiments, PAI-1 deficiency significantly increased ALP activity and mineralization in mouse osteoblasts. Moreover, PAI-1 deficiency significantly increased ALP activity and up-regulated osteocalcin expression during osteoblastic differentiation from mouse adipose-tissue-derived stem cells, but suppressed the chondrogenic differentiation of these cells. In conclusion, the present study showed that PAI-1 deficiency promoted HO in Achilles tendons after trauma/burn treatment partly by enhancing osteoblast differentiation and ALP activity in mice. Endogenous PAI-1 may play protective roles against HO after injury and inflammation.

Can the Achilles tendon regenerate completely following percutaneous tenotomy in older children with clubfoot?

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. 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. Percutaneous Achilles tenotomy was performed on 31 children (48 clubfeet) at a mean age of 5.24 ± 2.14years (1-10.2years). At a mean follow-up of 4.86 ± 1.97years, 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 6.29cm (range 4-10cm). Normal fibrillar tendinous echotexture with homogenous echogenicity was seen on ultrasonography in 41 feet (85.4%) with mean tendon width of 9.7mm (3.3-16mm) and thickness of 5.1mm (1.8-15mm), comparable with unaffected feet. 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.

Radiographic Impact on the Clinical Decision Making of Achilles Tenotomy in Clubfoot: In Search of an Objective Cut-Off Value

Background: We tried to determine whether the indication of Achilles tenotomy (AT) in clubfoot patients based on clinical evaluation could be confirmed radiographically, and to find an objective radiographic cut-off value for its indication. Methods: Eighty-six clubfeet from 60 patients, (26 bilateral and 34 unilateral) were included. A standard Ponseti treatment regimen was applied. Group 1 comprised patients who underwent AT immediately after serial plaster casting (26 feet). Group 2 comprised patients who underwent AT during the follow-up period (48 feet). Group 3 comprised patients who were assumed to have a corrected foot and did not undergo AT (12 feet). Group 4 comprised the healthy sides of the unilateral cases (34 feet). Results: Both Group 1 and Group 2 showed significant improvement after tenotomy (p = 0.002). In order to differentiate between the normal and AT groups according to the pre-tenotomy angle, we obtained an optimal cut-off value of &gt;85° according to the Youden index, a sensitivity of 96%, a specificity of 91.2%, a positive predictive value of 95.9%, a negative predictive value of 91.2%, and an accuracy rate of 94.4% (AUC: 0.983; p &lt; 0.001). Conclusions: Feet with a lateral tibio-calcaneal angle &gt; 85° can be considered pathologic and accepted as candidates for AT.

Improving Prenatal Diagnosis Precision for Congenital Clubfoot by Using Three-Dimensional Ultrasonography.

Prenatal diagnosis of clubfoot traditionally relied on two-dimensional ultrasonography. To enhance diagnosis and predict postnatal outcomes, we examined the parameters that differentiate pathological clubfoot using three-dimensional ultrasonography. In our retrospective study, we examined the findings of prenatal ultrasound and the postnatal outcomes of pregnancies with suspected congenital clubfoot between 2018 and 2021. Based on the three-dimensional perspective, we measured the angles of varus, equinus, calcaneopedal block, and forefoot adduction and compared the sonographic variables between the postnatal treated and non-treated groups. We evaluated 31 pregnancies (47 feet) with suspected clubfoot using three-dimensional ultrasonography. After delivery, a total of 37 feet (78.7%) underwent treatment involving serial casting only or additional Achilles tenotomy. The treated group showed significantly greater hindfoot varus deviation (60.5° vs. 46.6°, p = 0.026) and calcaneopedal block deviation (65.6° vs. 26.6°, p < 0.05) compared to the non-treated group. The calcaneopedal block had an area under the curve of 0.98 with a diagnostic threshold of 46.2 degrees (sensitivity of 97%, specificity of 90%, positive predictive value of 97%, and negative predictive value of 90%). During prenatal evaluation of clubfoot using three-dimensional ultrasonography, the calcaneopedal block deviation has the potential to predict postnatal treatment.

CAN THE PIRANI SCORE PREDICT THE NECESSITY OF ACHILLES TENOTOMY FOR IDIOPATHIC CLUBFOOT PATIENTS TREATED WITH THE PONSETI METHOD?

Background: Idiopathic clubfoot is one of the most common congenital problems affecting newborns. Several methods are used for grading its severity, of which Pirani score is the most reliable one. The Ponseti method of clubfoot management is effective, producing better results and fewer complications than traditional surgical methods. Methods: The study includes 27 clubfeet who were diagnosed with clubfoot and who were scored using Pirani score and were treated with the Ponseti method with possible Achilles tenotomy. Result: The study showed that the mean Pirani scores before treatment were significantly higher in the tenotomy than in the non-tenotomy group (3.54 vs. 2.23 for the total Pirani score, 2.25 vs. 1.69 for the midfoot Pirani score and 1.29 vs. 0.59 for the hindfoot Pirani score). The study proposes a “before treatment” cutoff point of 2.75 for the total Pirani score, 1.75 for the midfoot Pirani score and 1.25 for the hindfoot Pirani score, where a score above these cutoff points can predict the need for tenotomy. Conclusion: This study showed that the Pre-treatment Pirani score can help surgeons decide whether to do tenotomy or not in patients treated with the Ponseti method.
