Tenotomy Of Achilles Tendon Research Articles

Percutaneous Achilles tendon tenotomy in clubfoot with a blade or a needle: a single-centre randomized controlled noninferiority trial.

The gold standard for percutaneous Achilles tendon tenotomy during the Ponseti treatment for idiopathic clubfoot is a tenotomy with a No. 15 blade. This trial aims to establish the technique where the tenotomy is performed with a large-bore needle as noninferior to the gold standard. We randomized feet from children aged below 36 months with idiopathic clubfoot on a 1:1 basis in either the blade or needle group. Follow-up was conducted at three weeks and three months postoperatively, where dorsiflexion range, Pirani scores, and complications were recorded. The noninferiority margin was set at 4° difference in dorsiflexion range at three months postoperatively. The blade group had more dorsiflexion at both follow-up consultations: 18.36° versus 18.03° (p = 0.115) at three weeks and 18.96° versus 18.26° (p = 0.001) at three months. The difference of the mean at three months 0.7° is well below the noninferiority margin of 4°. There was no significant difference in Pirani scores. The blade group had more extensive scar marks at three months than the needle group (8 vs 2). No major complications were recorded. The needle tenotomy is noninferior to the blade tenotomy for usage in Ponseti treatment for idiopathic clubfoot in children aged below 36 months.

Clinical and Sonographic Evaluation of Percutaneous Achilles Tendon Tenotomy in Idiopathic Clubfoot: A Prospective Study

Objectives: Idiopathic Congenital Talipes Equino Varus (CTEV), commonly referred to as Clubfoot, is a complex musculoskeletal deformity affecting infants. The Ponseti technique, a gold standard approach, has emerged as an effective treatment. This study aims to evaluate the clinical and sonographic outcomes of percutaneous Achilles tendon tenotomy in children with idiopathic clubfoot who underwent the Ponseti procedure. Methods: A prospective study was conducted at the JIPMER Department of Orthopaedics, involving 41 feet with residual equinus deformity following Ponseti treatment. Infants with idiopathic clubfoot were included. Clinical and sonographic evaluations were performed, percutaneous Achilles tendon tenotomy was performed. Parameters were measured, Data were statistically analyzed using Kolmogorov-Smirnov tests, paired t-tests, ANOVA, and correlation analysis. Results: 29 infants (41 feet), primarily boys (89.7%) were studied. Following percutaneous tenotomy, clinical improvement was observed, with a mean increase in dorsiflexion of 20-25 degrees. Sonographic parameters showed significant improvement in tibio calcaneal distance, talocalcaneal divergence, and metaphyseal-talocalcaneal angle post-tenotomy (p<0.05). Positive correlations were found between clinical and sonographic improvements. Conclusion: Clinical improvement of hindfoot deformity following percutaneous Achilles tendon tenotomy in idiopathic clubfeet correlates with the sonological improvement of talo calcaneal, tibio calcaneal angles and tibio calcaneal distance.

A single-center, single-blinded, randomized, parallel-group, non-inferiority trial to compare the efficacy of a 22-gauge needle versus a 15 blade to perform an Achilles tendon tenotomy in 244 clubfeet—study protocol

BackgroundAchilles tendon tenotomy is an integral part of the Ponseti method, aimed at correcting residual equinus and lack of dorsiflexion after correction of the adductus deformity in clubfoot. Percutaneous tenotomy using a number 15 scalpel blade is considered the gold standard, resulting in excellent results with minimal complications. The use of a large-bore needle to perform Achilles tendon tenotomies has been described in literature, but a large-scale randomized controlled trial is currently lacking. In this trial, we aim to show the non-inferiority of the needle tenotomy technique compared to the gold standard blade tenotomy technique.MethodsWe will randomize 244 feet into group A: needle tenotomy or group B: blade tenotomy. Randomization will be done using a block randomization with random block sizes and applying a 1:1 allocation to achieve an intervention and control group of the exact same size. Children will be evaluated at 3 weeks and 3 months post-tenotomy for primary and secondary clinical outcomes. The primary clinical outcome will be the range of dorsiflexion obtained the secondary clinical outcomes will be frequency of minor and major complications and Pirani score. The non-inferiority margin was set at 4°, and thus, the null hypothesis of inferiority of the needle technique will be rejected if the mean difference between both techniques is less than 4°. The statistical analysis will use a multi-level mixed effects linear regression model for the primary outcomes and a multi-level mixed effects logistic regression model for the secondary clinical outcomes. The physician performing the evaluations post-tenotomy will be the only one blinded to group allocation.Trial registrationThis trial was registered prospectively with ClinicalTrials.gov registration number: NCT04897100 on 21 May 2021.

TNFα-dependent mTOR activity is required for tenotomy-induced ectopic ossification in mice.

Ectopic ossifications often occur in skeletal muscles or tendons following local trauma or internal hemorrhage, and occasionally cause severe pain that limits activities of daily living. However, mechanisms underlying their development remain unknown. The right Achilles tendon in 8-week-old female or male mice was dissected. Some mice were injected intraperitoneally either with phosphate-buffered saline, dimethyl sulfoxide, cimetidine, rapamycin, celecoxib or loxoprofen for 10 weeks. One week after surgery, immunohistochemical analysis was performed for mTOR, TNFα or F4/80. Ten weeks after surgery, ectopic ossification at the tenotomy site was detected by 3D micro-CT. Ectopic ossification was seen at dissection sites in all wild-type mice by dissection of the Achilles tendon. mTOR activation was detected at dissection sites, and development of ectopic ossification was significantly inhibited by administration of rapamycin, an mTOR inhibitor, to wild-type mice. Moreover, administration of the histamine 2 blocker cimetidine, which reportedly inhibits ectopic ossification in tendons, was not effective in inhibiting ectopic ossification in our models. TNFα-expressing F4/80-positive macrophages accumulate at dissection sites and that ectopic ossification of the Achilles tendon dissection was significantly inhibited in TNFα-deficient mice in vivo. Ectopic ossification is significantly inhibited by administration of either celecoxib or loxoprofen, both anti-inflammatory agents, in wild-type mice. mTOR activation by Achilles tendon tenotomy is inhibited in TNFα-deficient mice. The TNFα-mTOR axis could be targeted therapeutically to prevent trauma-induced ectopic ossification in tendons.

Percutaneous Achilles tendon tenotomy in clubfoot patients with a 22 gauge needle in a low-resource setting.

Ponseti treatment has been well-established as the gold standard for the treatment of idiopathic clubfoot in high-income countries and middle- and low-income countries (LMICs). The tenotomy is usually performed in the clinic using a scalpel blade under local anesthesia. However, we believe that by adapting the technique from Minkowitz et al. to a low-resource setting, we can help address some of the known barriers to Ponseti care. Using a needle instead of a blade makes the procedure less cumbersome easier to learn and easier to understand for the provider, family and the patient. We were able show that the needle tenotomy technique can be implemented in a low-resource setting like Pakistan, and can be performed using only one assistant and materials that are locally and readily available for the same cost This paper and its attached educational videos can help spread the technique among providers in low-resource settings.

Effectiveness of Needle Tenotomy for Correction of Equinus in Clubfoot.

During the COVID-19 surge, due to a lack of operating room availability, we performed Achilles tendon tenotomy in clubfoot patients using a 16/18 gauge needle to avoid delay in their management. The procedures were performed on an outpatient basis. The current retrospective study aims to investigate the effectiveness of needle tenotomy for the correction of equinus in clubfoot at a minimum of one year of follow-up. Clinical records of all clubfoot patients that underwent needle tenotomy of Achilles tendon from March 2020 onwards with at least one year of follow-up were reviewed. We recorded Pirani scores and the equinus deformity at the initial presentation, after Achilles tendon tenotomy, and at the final follow-up. We also recorded any procedure-related complications following the Achilles tendon tenotomy. We compared dorsiflexion after final cast removal and after one year of follow-up. A total of 26 clubfeet in 14 patients underwent needle tenotomy of the Achilles tendon and completed one year of follow-up. Ankle dorsiflexion was achievable in all patients and the mean dorsiflexion of 27.4 degrees. The average Pirani score after tenotomy at final cast removal was 0.16, while the mean dorsiflexion at final cast removal was 24.2 degrees (p = .00084).No tenotomy procedure-related complications were noted. Percutaneous needle tenotomy of the Achilles tendon is a simple, safe, and effective technique for equinus correction in clubfoot. Considering the less invasive nature of the procedure, it can be done as a short procedure on an outpatient basis and has a limited risk of hemorrhage and other wound-related complications.

Understanding congenital vertical talus

Congenital vertical talus (CVT) is a rare foot deformity that presents with a rigid flat foot at birth. CVT can present as an isolated abnormality in the newborn, however in at least 50% of cases in association with other conditions. Full neuro-axial imaging is essential to detect any associated neurologic problems. Radiographs of the foot, including forced plantar and dorsiflexion laterals, are diagnostic. Gold standard modern treatment uses the Dobbs method of serial manipulation and casting with minimally-invasive stabilization of the talonavicular joint and Achilles tendon tenotomy.

Current understandings in congenital talipes equinovarus

Congenital talipes equinovarus is one of the most common lower limb congenital defects present at birth. The gold standard treatment is the Ponseti method and it harnesses the biomechanical properties of biological tissues. It involves serial gentle manipulation and casting. Part of this method is an Achilles tendon tenotomy prior to the final casts, boots and bars and if needed a tibialis anterior transfer for dynamic supination at a later stage. The Ponseti method does not result in normal feet but results in normal looking feet that are comfortable and function normally.

Outcomes of the Clubfoot Treatment with the Ponseti Method: Recurrence and Prognostic Factors

Background: Clubfoot is a multifactorial disease with the prevalence of one in 1000 live births. The presentations of clubfoot are forefoot adductus, hindfoot varus, cavus, and equinus. Ponseti method is an efficient nonoperative clubfoot treatment containing manipulation, serial casting, and Achilles tendon tenotomy if necessary. Our prospective observational study assessed the outcome and probability of recurrence in the treated clubfoot with the Ponseti method.
 Methods: This prospective observational study was performed in Akhtar Hospital in Tehran, Iran. 27 patients with 38 feet of idiopathic clubfoot in our study were treated with the Ponseti method. The patients were assessed before and after treatment and demographic characteristics, Dimeglio scores, number of recurrenes, and need for tenotomy were recorded.
 Results: All patients (38 feet) successfully achieved complete deformity correction, but 13 feet had a relapse. The mean age of cases with relapse was more than cases without relapse. Cases with a higher initial Dimeglio score had a higher recurrence rate after Ponseti method treatment. Eight feet (five patients) out of 38 feet did not use Denis Browne (DB) splint as our protocol; all of them had a relapse. On the other hand, only 5 of 30 feet (16.7%) that used splint had recurrence.
 Conclusion: The treatment should be started as soon as possible because it is more effective at a younger age. Severe cases at the initial visit had more recurrence rate. Besides, the recurrence rate in cases that used DB orthosis improperly, irregularly, and incorrectly was higher than others.

Does the use of ultrasound guidance during percutaneous Achilles tendon tenotomy improve outcomes of clubfoot management? A randomized controlled trial.

Achilles tenotomy is a crucial aspect in the non-operative management of clubfoot as per Ponseti's casting protocol. Achilles tenotomy is routinely carried out percutaneously in a blind manner without any image guidance. This study aimed to determine the role of ultrasound-guided percutaneous Achilles tenotomy (PAT) in improving outcomes in clubfoot management. There are no previous studies that have explored the role of image guidance in PAT. This prospective, single-center randomized control trial included 50 clubfoot cases (74 feet) planned for PAT at a mean age of 30.2 months. A single experienced senior surgeon performed tenotomies. Patients were randomized to two groups, with the tenotomies performed under ultrasound guidance in one group (test group) and PAT carried out without image guidance in the other (control) group. Outcome measures assessed included rate of complications, immediate postoperative FLACC score for pain severity and Pirani score at a minimum follow-up of 12 months. There were no significant differences in the complication rates between the test and control groups regarding bleeding, nerve injury and incomplete tenotomies. The mean pain FLACC score was significantly higher in the control group (PAT without image guidance) (P = 0.03), suggesting that the child would better tolerate the ultrasound-guided procedure. All patients in both groups had a Pirani score of zero and plantigrade feet at final follow up, with no relapses. Ultrasound-guided PAT does not have any added advantage over PAT with clinical examination without image guidance in terms of long-term outcomes. Level of evidence: Therapeutic level II.

Inhibition of glucose use improves structural recovery of injured Achilles tendon in mice.

Injured tendons do not regain their native structure except at fetal or very young ages. Healing tendons often show mucoid degeneration involving accumulation of sulfated glycosaminoglycans (GAGs), but its etiology and molecular base have not been studied substantially. We hypothesized that quality and quantity of gene expression involving the synthesis of proteoglycans having sulfated GAGs are altered in injured tendons and that a reduction in synthesis of sulfated GAGs improves structural and functional recovery of injured tendons. C57BL6/j mice were subjected to Achilles tendon tenotomy surgery. The injured tendons accumulated sulfate proteoglycans as early as 1-week postsurgery and continued so by 4-week postsurgery. Transcriptome analysis revealed upregulation of a wide range of proteoglycan genes that have sulfated GAGs in the injured tendons 1 and 3 weeks postsurgery. Genes critical for enzymatic reaction of initiation and elongation of chondroitin sulfate GAG chains were also upregulated. After the surgery, mice were treated with the 2-deoxy-d-glucose (2DG) that inhibits conversion of glucose to glucose-6-phosphate, an initial step of glucose metabolism as an energy source and precursors of monosaccharides of GAGs. The 2DG treatment reduced accumulation of sulfated proteoglycans, improved collagen fiber alignment, and reduced the cross-sectional area of the injured tendons. The modulus of the 2DG-treated groups was higher than that in the vehicle group, but not of statistical significance. Our findings suggest that mucoid degeneration in injured tendons may result from the upregulated expression of genes involved the synthesis of sulfate proteoglycans and can be inhibited by reduction of glucose utilization.

Prenatal diagnosis of isolated clubfoot: Diagnostic accuracy and long-term postnatal outcomes

ObjectiveTo evaluate concordance between prenatal and postnatal diagnosis of congenital talipes equinovarus (cTEV), rates of surgery and postnatal outcomes in relation to the prenatal classification of severity. Study designThis is a retrospective observational cohort study on fetuses with a prenatal diagnosis of cTEV between 2004 and 2018. All cases of isolated cTEV in singleton pregnancies were included. Postnatally, the Ponseti method was applied. Children were followed-up postnatally for at least two years, with a specific focus on neurodevelopmental outcome. ResultsThe cohort included 81 fetuses with a prenatal diagnosis of cTEV confirmed postnatally in 86.4% of cases. Concordance between prenatal and postnatal assessment was good for both laterality and degree of severity (k = 0.61 and 0.66, respectively). The average Pirani score, number of casts and rates of Achilles tendon tenotomy were higher for III degree cTEV (p < 0.001). Within this group only, the rate of relapse was 11% and the rates of major surgery was 6%. The postnatal outcome was normal in 68.6% newborns, while 14% of cases had a diagnosis of minor additional findings and 17% had an impairment of neurological development. None of the outcome was statistically correlated to the prenatal assessment of laterality or degree. ConclusionsThe accuracy of prenatal ultrasound for isolated cTEV is 86% with a false positive diagnosis of 14%. The grade of cTEV assigned prenatally correlates to postnatal severity and longer orthopedic rehabilitation in terms of number of casts and need of surgery. The assessment of the correlation between cTEV and neurological impairment requires further prospective studies on larger cohorts.

Expression and significance of related genes in the early stage of post-traumatic heterotopic ossification in a rat model of Achilles tenotomy.

This study aims to determine expression profiles of relevant genes in the early stages of post-traumatic heterotopic ossification (HO) in a rat model of Achilles tenotomy. A total of 80 male Sprague-Dawley rats were randomly assigned to two groups: the HO group and the control group. Tenotomy was performed in the Achilles tendon of the rats in the HO group, and no intervention was conducted in the control group. On the 3rd, 5th, 8th, and 14th days after the operation, 8 rats were taken from each group at each time point, and the Achilles tendon and surrounding tissue specimens were collected. Gene expressions of TGF-β, BMP, GDF, IL, and MMP families as well as TNF-α, HIF-1α chordin, gremlin, noggin, and NODAL were analyzed by qRT-PCR. The relevant genes that were highly expressed at different time points were screened, and immunohistochemical staining was then used to verify their expression. At the 10th week, HO formation was explored by radiographic and histological examination in the remaining 8 rats of each group. Both the radiographic and histological analyses indicated that all the rats developed HO in the HO group (100%), whereas no HO occurred in the control group. Surrounding tissues obtained from the HO group showed significantly higher gene expressions of TGF-β1, BMP-1, IL1β, HIF-1α, and MMP-2 but lower expressions of BMP-4, GDF-8, and TNF-α compared with the control group. In addition, immunohistochemical staining confirmed the higher protein expression levels of relevant genes in the HO group. TGF-β1, BMP-1, IL-1β, HIF-1α, MMP-2, BMP4, GDF-8, and TNF-α may be associated with the formation of traumatic HO; and BMP4, GDF-8, and TNF-α may play a protective role in the early stage of HO. In this study, we investigated the expression levels of the related cytokines in the early stages of traumatic HO in the Achilles tendon tenotomy rat model to better understand the pathogenesis of HO.

Histological evaluation of the effect of low-frequency electric stimulation on healing Achilles tendons in rats.

ABSTRACTPurpose:Histologically evaluate the effects of low frequency electrical stimulation in the treatment of Achilles tendon injuries in rats.Methods:Thirty-four rats underwent Achilles tendon tenotomy and tenorrhaphy. They were randomly allocated in two groups. Half of the sample constituted the experiment group, whose lesions were stimulated with 2 Hz, nonpolarized current and 1 mA, for 14 days. The other animals formed the control group. They were evaluated at 2, 4 and 6 weeks. The histological study was carried out, the collagen density and the wound maturity index were measured.Results:The healing score was higher in the group stimulated at the 6th week (p = 0.018). The density collagen 1 was higher in the group treated at the three times (p = 0.004) and that collagen 3 was higher in the group treated at 6 weeks (p = 0.004). Together, collagen 1 and 3 were higher in the group stimulated at 4 and 6 weeks (p = 0.009, p = 0.004). The maturity index was higher in this group at the three moments (p = 0.017 p = 0.004 and p = 0.009).Conclusion:Low frequency electric stimulation improved healing and increased the quantity of collagen.

Analysis of the efficacy of the Ponseti method for treatment of secondary clubfoot in young children with tethered cord syndrome

Objective: To explore the feasibility of Ponseti method in treatment of secondary clubfoot in young children with Tethered Cord Syndrome(TCS). Methods: The clinical data of 53 young children with clubfeet treated with Ponseti method from March 2014 to March 2017 at Department of Pediatric Orthopedics, the Third Affiliated Hospital of Zhengzhou University were analyzed retrospectively. These patients were divided into TCS group and Idiopathic group according to the etiology. There were 19 patients (33 feet) in TCS group,with an mean age of 2.8 months(range:0.2 to 24.0 months), including 13 males and 6 females, 5 patients with unilateral clubfeet and 14 patients with bilateral clubfeet. There were 34 patients (45 feet) in idiopathic group, with an mean age of 3.1 months(range: 0.1 to 21.0 months), including 18 males and 16 females, 23 patients with unilateral clubfeet and 11 patients with bilateral clubfeet. All the children received casts correction according to Ponseti method, and were followed up at 3 weeks, 3 months, 6 months and every 6 months after the Achilles tendon tenotomy or the last cast correction. Complications were recorded and therapeutic effect was evaluated of these children by Dimeglio Scoring System and the International Clubfoot Study Group (ICFSG) at the last follow-up. Independent t test, Mann-Witney U test or χ(2) test were used to compare the indicators of the two groups. Results: The number of plaster fixation in TCS group was (6.1±2.0) times, and that of idiopathic group was (4.8±1.0) times(t=3.482, P<0.01).In TCS group, 22 feet treated with Achilles tendon transection and that of idiopathic group was 40 feet(χ(2)=0.279, P=0.598). There were 18 cases recurrence in TCS group and 8 cases in Idiopathic group (t=11.149, P<0.01). In TCS group, 16 cases (27 feet) completed the initial correction, the success rate was 60.6% (27/33), 3 cases (6 feet) could not correct the deformity after 9 to 10 times of plaster fixation, and then underwent soft tissue release.In idiopathic group, 34 cases (45 feet) achieved initial correction after Ponseti treatment(χ(2)=6.488, P=0.011).At the last follow up, there were 5 cases (9 feet) in TCS group and 2 cases (2 feet) in idiopathic group underwent soft tissue release(χ(2)=6.110, P=0.013). The classification grade of ICFSG score of the two groups without soft tissue release were (2.1±0.6) and (1.8±0.7), the difference was not statistically significant (t=1.765, P=0.082). All the children had no skin ulceration, bedsores, skin allergy and other complications. Conclusion: Ponseti method is effective in the treatment of clubfoot secondary to TCS, and the functional recovery is similar to that of children with idiopathic clubfoot.

Circumventing tenotomy in idiopathic clubfoot

Background: Congenital talipes equinovarus (CTEV) is one of the most common congenital deformities faced by the orthopaedic fraternity. Although, the deformity is treated conservatively initially with Ponseti’s method, the procedure involves performing percutaneous Achilles tendon tenotomy, a procedure that has its own set of potential complications. We describe a novel manipulation technique to circumvent tenotomy in correcting the residual equinus deformity of idiopathic clubfoot. Materials and methods: A total of 30 (43 clubfeet) patients were included in the study and after the correction of cavus, adduction and varus deformity using Ponseti’s method, the residual equinus deformity was corrected using our technique. Results: All the cases with the residual equinus deformity could be corrected by our technique. Conclusion: Idiopathic CTEV presenting within a year can successfully be treated without performing percutaneous tendoachilles tenotomy irrespective of the initial Pirani score at presentation using the manipulation technique employed by us.

Adaptive and innate immune cell responses in tendons and lymph nodes after tendon injury and repair.

Tendon injuries are a common clinical condition with limited treatment options. The cellular components of the innate immune system, such as neutrophils and macrophages, have been studied in tendon injuries. However, the adaptive immune system, comprising specialized lymphocytes, plays an important role in orchestrating the healing of numerous tissues, but less is known about these cells in tendon healing. To gain a greater understanding of the biological processes that regulate tendon healing, we determined how the cellular components of the adaptive and innate immune system respond to a tendon injury using two-month-old male mice. We observed that lymphatic vasculature is present in the epitenon and superficial regions of Achilles tendons, and that the lymphatics drain into the popliteal lymph node. We then created an acute Achilles tenotomy followed by repair, and collected tendons and popliteal lymph nodes 1, 2, and 4 wk after injury. Tendon injury resulted in a robust adaptive immune cell response that followed an initial innate immune cell response in tendons and lymph nodes. Monocytes, neutrophils, and macrophages initially accumulated at 1 wk after injury in tendons, while dendritic cells and CD4+ T cells peaked at 2 wk after injury. B cells and CD8+ T cells progressively increased over time. In parallel, immune cells of the popliteal lymph node demonstrated a similarly coordinated response to the injury. These results suggest that there is an adaptive immune response to tendon injury, and adaptive immune cells may play a role in regulating tendon healing.NEW & NOTEWORTHY While the innate immune system, consisting of macrophages and related hematopoietic cells, has been studied in tendon injury, less is known about the adaptive immune system. Using a mouse model of Achilles tendon tenotomy and repair, we observed an adaptive immune cell response, consisting of CD4+ and CD8+ T cells, and B cells, which occur through 4 wk after tendon injury. This response appeared to be coordinated by the draining popliteal lymph node.

One-week accelerated PONSETI method in the management of idiopathic clubfeet

Purpose: This study aims to evaluate the results of the 1-week accelerated PONSETI method in the management of idiopathic clubfeet implemented by Ahmad and Aker in which manipulations, five castings, and Achilles tendon tenotomy are done in a week. Methods: We studied 15 patients with 22 moderate-to-severe congenital idiopathic clubfeet treated by the 1-week accelerated PONSETI method. The method involves the manipulation of the deformed foot and the first casting in the 1st day, with the second, third, fourth, and fifth castings (if the foot is not fully corrected, additional casting is done till reaching fully initial correction) in the 4th, 5th, 6th, and 7th day postmanipulation. After removal of the last cast, Achilles tenotomy was performed with subsequent 3-week casting in all patients. The Pirani scores were used for comparing the results before starting the treatment and after removal of the final cast. Results: We had 15 patients (7 bilateral and 8 unilateral) of clubfoot. The average age at the treatment was 15.2 days (range = 1–90 days). All patients, who had moderate-to-severe congenital idiopathic clubfeet with a Pirani score of 4–6 (mean = 5.61), underwent the 1-week accelerated PONSETI technique. After removal of the 3-week cast, the scores were 0 for all cases (except 3 feet with Pirani score of 0.5), which was an indication for deformity correction to achieve acceptable feet in all patients without the experience of any short-term complications. Conclusions: Our study of the 1-week accelerated PONSETI technique was found to be safe and effective for the initial correction of severe idiopathic clubfoot deformity in children less than 3 months of age and confirmed the results reported by Ahmad and Aker's study but still needs more follow-up of the patients to confirm the results on the long term.

Отдаленные результаты лечения детей с врожденной вертикальной таранной костью

Objective To review long-term results of congenital vertical talus treated with classical techniques and a minimally invasive treatment approach offered by M. Dobbs. Material and methods Review of 30 pediatric cases (54 feet) with severe congenital convex pes valgus was performed over the period of 11 years. Patient ages ranged from 1 month to 13 years at the start of treatment. The 54 primary operations performed included triple arthrodesis (n = 2), open talus reduction according to S.J. Kumar, K.R. Cowell, D.L. Ramsey (n = 5), Coleman open reduction of the talus and screw fixation (n = 6), serial casting and percutaneous fixation of the talonavicular joint with a Kirschner wire and a percutaneous Achilles tendon tenotomy (n = 41). Reduction of the talus was produced under vision and followed by capsuloplasty of 23 feet. C-arm was used for closed correction in the rest of the cases. Results A minimally invasive Dobbs approach that consisted in serial casting, minimal surgery followed by bracing was shown to provide favorable outcomes in 21 patients (41 feet) treated at early childhood. Recurrent deformity with the oblique talus developed in 3 cases (4 feet) during growth of an average 6.1 years despite satisfactory primary correction and required further interventions. However, open reduction has become a rare procedure in the patient cohort with introduction of Dobbs practice at our hospital. There are more reports of successful primary treatment with Dobbs method in the national literature with no long-term follow-ups available in our country. Conclusions Kumar and Coleman operative interventions are reserved for unrecognized or recurrent cases following Dobbs manipulations. Triple arthrodesis as a definitive procedure can be used in a late detection of the condition or poor outcomes.

Accelerated Ponseti method: First experiences in a more convenient technique for patients with severe idiopathic club feet

BackgroundCongenital Idiopathic Talipes Equinovarus (CTEV), or clubfoot, is a complex deformity that involves pathological anatomy in the foot with ankle equinus, hindfoot varus, midfoot cavus and forefoot adductus [1]. Universal agreement is established about Ponseti technique as the initial management for this deformity. This preliminary study aims to investigate the possibility of having a braceable foot through a proposed accelerated Ponseti method by which, manipulations, 5 castings and Achilles tendon tenotomy are implemented in a week. MethodsThis study included 11 patients with 16severe congenital idiopathic clubfeet treated by an accelerated Ponseti method. The method involves manipulation of the deformed foot, and 1st casting in one day, with the 2nd, 3rd, 4th, 5th castings in the 4th, 5th, 6th, 7th day post-manipulation. After the 4th cast removal, Achilles tenotomy was performed with subsequent three-week casting for all patients. Nonparametric tests were used for comparing the Pirani scores before starting the treatment and after removal of final cast. ResultsFive patients had bilateral club foot deformity. Average age at treatment was 54.8 days (range 8–150days). All patients, who had severe congenital idiopathic club feet with a Pirani score of 6, underwent the accelerated Ponseti technique. After removal of the three-week cast, the scores median was 0.59, (range 0–1.5), indicating a correction of the deformity and having braceable feet in all patients without experiencing any short-term complication. ConclusionsThe first step accelerated Pnoseti technique was found to be safe and effective for initial correction of severe idiopathic clubfoot deformity in children below three months of age , though it is an initial study that needs more studies with more follow up data.
