Safety and long-term effects on gait of hemiplegic patients in equinovarus foot deformity surgical correction followed by immediate rehabilitation: a prospective observational study.

BACKGROUND: Equinovarus foot deformity (EVFD) is the most common lower limb deformity in stroke patients. Immobilization following EVFD surgical correction is known to have a negative impact on muscle rearrangement with possible loss of walking ability in stroke patients. In a previous study, safe and positive effects at one-month follow-up after surgery were obtained with an early rehabilitation treatment (ERT) characterized by immediate walking and training. AIM: To determine long-term safety and efficacy of functional surgery followed by early rehabilitation (FSER). DESIGN: A 12 months prospective observational study. SETTING: Outpatients clinic, Gait and Motion Laboratory, Sol et Salus Hospital, Rimini, Italy. POPULATION: Twenty-four adult chronic stroke survivors with EVFD surgical correction followed by ERT, age 55±13 years, affected side 12L/12R, time from lesion 5±4 years. METHODS: Patients received clinical and instrumental evaluation by gait analysis (GA) before (T0), one, three and twelve months after surgery. Safety was defined as the absence of any complication consequent to FSER. Efficacy was assessed by the recovery in ankle kinematics, walking speed and space-time parameters. RESULTS: No clinical complication (thrombosis, surgical wound infection, muscle or tendon injury, muscle hematoma) arose in the sample during the follow-up year. Variables relating to ankle kinematics improved towards their normal values at one month after surgery. These were maintained at 3 and 12 months, with a significant difference between follow-ups and pre-surgical values (Durbin-Conover Test, P<0.01). Gait speed, cadence, anterior step length and stride length of the affected side showed a statistical improvement at 3 and 12 months (Wilcoxon test, P=0.012 and P=0.001, respectively). Stride width decreased at 1 month after surgery and showed a further stable reduction at 3 months (P=0.008). CONCLUSIONS: The ERT protocol with immediate rehabilitation starting on the first day after surgical correction was safe and effective in providing a long-term correction of EVFD. Ankle dorsiflexion improved both in stance and swing, allowing for a significative improvement in walking speed. CLINICAL REHABILITATION IMPACT: FSER can be considered an encouraging approach in the management of EVFD, with durable results.

Gross Motor Function at 10 Years of Age in Children With Clubfoot Following the French Physical Therapy Method and the Ponseti Technique.

PURPOSE: To evaluate gross motor skills [Bruininks-Oseretsky Test of Motor Proficiency, 2nd ed (BOT-2)] of patients with idiopathic clubfoot initially treated nonoperatively with either the French functional physical therapy (PT) method or the Ponseti technique, at age 10 years. METHODS: The BOT-2 was administered by trained physical therapists on patients with idiopathic clubfoot at age 10 years. The cohort was divided by initial treatment method (PT or Ponseti), and compared. Subsequent analyses included comparisons of: initial clubfoot severity (Dimeglio scores: ≤13 vs. >13), laterality (unilateral vs. bilateral), and surgical versus nonoperative outcome. RESULTS: Of the 183 patients tested, 172 were included. The Ponseti and PT groups did not significantly differ according to age, height, weight, body mass index, ankle dorsiflexion, sex, average initial Dimeglio score, laterality, or surgical versus nonsurgical outcome. Overall, patients with treated clubfoot had average gross motor BOT-2 scores compared with age-matched peers. Patients in the PT group scored higher on Running Speed/Agility (P=0.019), Body Coordination percentile rank (P=0.038), and Strength and Agility percentile rank (P=0.007) than patients treated by the Ponseti technique. Patients with bilateral clubfoot scored significantly lower on the Balance subtest (P<0.01), and Body Coordination percentile rank (P<0.01), than those with unilateral clubfoot. Patients who required surgery scored significantly lower on the Balance subtest (P=0.04) than those who did not require surgery. CONCLUSIONS: Clubfoot may impair balance in 10 year olds with bilateral involvement and those requiring surgery. Future research should evaluate whether components of the PT method may improve gross motor outcomes as a supplement to the Ponseti technique. LEVELS OF EVIDENCE: Level II.

How Many Patients Who Have a Clubfoot Treated Using the Ponseti Method are Likely to Undergo a Tendon Transfer?

BACKGROUND: The Ponseti method has become the standard of care for the treatment of idiopathic clubfoot. A commonly reported problem encountered with this technique is a relapsed deformity that is sometimes treated in patients older than 2.5 years by an anterior tibial tendon transfer (ATTT) to the third cuneiform. Presently, there is insufficient information to properly counsel families whose infants are beginning Ponseti treatment on the probability of needing later tendon transfer surgery. METHODS: All idiopathic clubfoot patients seen at the authors' institution during the study period who met the inclusion criteria and who were followed for >2.5 years were included (N=137 patients). Kaplan-Meier Survival analysis was used to determine the probability of survival without the need for ATTT surgery. In addition, the influence of patient characteristics, socioeconomic variables, and treatment variables on need for surgery was calculated. RESULTS: On the basis of the survivorship analysis, the probability of undergoing an ATTT remained below 5% for all patients at 3 years of age, but exceeded 15% by 4 years of age, increasing steadily afterwards such that by 6 years of age, the probability of undergoing an ATTT reached 29% of all patients. Overall, controlling for all other variables in the analysis, parent-reported adherence with bracing reduced the odds of undergoing surgery by 6.88 times, compared with parent-reported nonadherence (P<0.01). CONCLUSIONS: This is the first study to report the probability of undergoing ATTT surgery as a function of age using survivorship analysis following Ponseti clubfoot treatment. Although the overall probability reached 29% at 6 years, this was significantly reduced by compliance with bracing. This information may be useful to the clinician when counseling families at the start of treatment. LEVEL OF EVIDENCE: Level III-theraputic.

Treatment of clubfoot with the modified Copenhagen method: A 10-year follow-up.

BACKGROUND: Clubfoot is one of the most frequent congenital malformations in the world. Non-operative methods follows limiting surgery to a minimum. The modified Copenhagen method has not been studied enough. STUDY DESIGN: longitudinal retrospective study. OBJECTIVES: To evaluate prognostic factors for clinical rehabilitation with the modified Copenhagen method in a 10-year follow-up period. METHODS: A retrospective study was carried out on a 10-year follow-up of 82 children diagnosed with clubfoot at birth and treated with the modified Copenhagen method. Their sex, side, severity, bilaterality, forefoot orientation, and age when the nonoperative treatment was started were registered, and a cluster analysis was performed to determine which variables were most significant for predicting whether surgical treatment was needed. RESULTS: Of the clubfeet, 13.4% were grade I, 65.9% were grade II, and 20.7% were grade III according to the Harrold and Walker classification. In total, 58 patients needed surgery at some point during the follow-up period. The severity and talo-first metatarsal angle made it possible to determine whether the patients required surgery in 68% (56/82) of the cases. CONCLUSION: The results of the study suggest the possibility of providing physicians with an algorithm which might facilitate assessing whether the children will require surgery or not, depending on the data obtained from the cluster analysis. Clinical relevance This study provides health professionals with an algorithm that might facilitate assessing whether the children will require surgery or not.

A Critical Evaluation of the Updated Evidence for Casting for Equinus Deformity in Children with Cerebral Palsy.

BACKGROUND AND PURPOSE: Equinus deformity is common in ambulant children with cerebral palsy (CP). Although lower leg casting is frequently used, the physiological basis for casting and effects beyond range of motion (ROM) gains are unclear. This review critically evaluates the updated evidence for casting in the management of ankle equinus in children with CP. METHODS: Comprehensive searches were conducted using electronic databases AMED, MEDLINE, CINAHL, Scopus, PEDro and the Cochrane Database of Systematic Reviews, publication years 2005-2014, in order to identify literature published since an earlier comprehensive systematic review. Only studies evaluating lower leg casting for conservative management of equinus deformity in children with CP were considered. Two independent raters critically appraised studies against the hierarchy of levels of evidence and rigour of study conduct questions proposed by the American Academy of Cerebral Palsy and Developmental Medicine's methodology for systematic review. RESULTS: Four relevant systematic reviews were identified, although these largely concerned earlier literature. Five original studies were included, all demonstrating improvement in dorsiflexion ROM. Combined treatment with botulinum toxin and casting offered greater and/or more sustained ROM gains than botulinum toxin alone in three studies. Effects on gait parameters and motor function were inconsistent. Participation outcomes were not evaluated. Methodological limitations make firm conclusions difficult. CONCLUSIONS: Recent years have offered little progress in the state of evidence for casting in the management of equinus deformity. Casting appears to offer at least short-term improvement in ankle dorsiflexion, although the proposition that this improves function or avoids surgery is not well substantiated. Future research needs to ensure more robust study design and broader evaluation across domains of the International Classification of Functioning, Disability and Health to determine the functional and long-term effect of casting for equinus deformity. Greater knowledge is required of the effect of casting on muscle structure and function in spastic CP. Copyright © 2015 John Wiley & Sons, Ltd.

Initial treatment of congenital idiopathic clubfoot: Prognostic factors.

BACKGROUND: The initial treatment of congenital idiopathic clubfoot (CIC) is nonoperative. Either the French physiotherapy method or the Ponseti casting method may be used. Whether either method is superior over the other remains unclear. However, the method used initially is not the only determinant of the final outcome. OBJECTIVE: The primary objective was to identify determinants of the final outcome as evaluated based on the need for surgical treatment and on the Ghanem-Seringe score. HYPOTHESIS: Factors associated with the final outcome can be identified. METHODS: Between 2004 and 2011, 100 CICs in 79 patients were treated in two centres, 47 using the French method and 53 the Ponseti method. The Dimeglio grade was determined at baseline and the Ghanem-Seringe score at last follow-up. Surgical procedures (if any), splinting duration, and rehabilitation therapy duration were recorded. The two groups showed no statistically significant differences for Dimeglio grade distribution, time from birth to treatment initiation, or mean follow-up. RESULTS: Factors significantly associated with a poor outcome by univariate analysis were use of the Ponseti method (P=0.0027), older age at last follow-up (P=3×10-4), initial Dimeglio grade (P=7×10-5), and need for surgery (P=10-5); no significant effect was found for splinting duration, rehabilitation duration, bilateral involvement, or antenatal diagnosis. By multivariate analysis, factors independently associated with a poor prognosis were older age at last follow-up, Dimeglio grade, and need for surgery. CONCLUSION: This study confirms the major prognostic significance of initial severity (Dimeglio grade) on the final outcome. The data do not firmly establish that one method is superior over the other. Nevertheless, the need for percutaneous Achilles tenotomy with the Ponseti method leads us to prefer the French physiotherapy method. LEVEL OF EVIDENCE: IV, retrospective study.

The effects of different types of ankle-foot orthoses on postural responses in individuals with walking impairments.

The aim of this study was to examine the immediate and long-term effects of different ankle-foot orthosis (AFO) types on postural responses in patients with various pathological conditions who, because of their walking disorders, wore an AFO. A total of 37 patients with different pathological conditions who visited the outpatient clinic for orthotics because of walking problems, already used or were referred for an AFO and had no other impairments that may influence balance were included in the study. The participants were divided into four groups according to the type of AFO that they wore. The postural responses were assessed with and without AFO using two force-plates following perturbations in different directions at the level of the pelvis. The centre of pressure was examined in the sagittal and frontal plane and compared with the normative data from healthy individuals. The results showed an improvement in postural responses to the lateral and backward perturbation directions when wearing the AFO, particularly responses in the anterior-posterior direction. The best results were achieved with the custom-made posterior leaf spring AFO for correction of equinovarus deformity. The time of wearing the AFO had an impact on postural responses in perturbation directions where the patients could not rely only on AFO. The custom-made AFO improved overall postural responses, especially dynamic stability, in lateral directions, whereas all stiff AFOs contributed towards an improvement in responses to all perturbations to the affected side. Results showed that long-term use of an AFO can be important for the overall improvement of postural responses.

Problems encountered by parents of infants with clubfoot treated by the Ponseti method in Madagascar: A study to inform better practice.

OBJECTIVE: Ponseti treatment for clubfoot is effective and inexpensive, improving children's social participation. Two rehabilitation centres in Madagascar piloted Ponseti treatment; however, at one centre 46% of infants failed to complete treatment. The aim of this study was to determine the causes of defaulting in order to facilitate subsequent improvements nationwide when treatment is rolled out to all centres. METHODS: Questionnaire-based interviews. PATIENTS: Twenty mothers of infants younger than 1 year were interviewed after 3 months of treatment in relation to difficulties they experienced with continuing treatment. RESULTS: Fifteen families of these had financial problems: 7 incurred debt, 2 sold possessions, 4 parents stopped work an 2 did not give any further details. All mothers experienced distress; 9 hid their child's foot, and 8 were accused of wrong-doing during pregnancy. Three families travelled more than 500 km to the treatment centre and journeys were costly and difficult. Ponseti splints were acceptable, but aftercare of the splints proved problematic. CONCLUSION: Repeated travel to the clinic resulted in financial and social burden on the families, which reduced their ability to engage in treatment. The findings of this study are similar to work from other countries, but publications on rehabilitation from Madagascar are few. Improved support for parents, information, splinting with better materials and provision of treatment more locally are needed. Financial support for parents is key to enhancing children's life chances.

[Rehabilitation and psychological follow-up of a child with talipes equinovarus]. / Impact psychologique dans la rééducation de l'enfant atteint d'un pied bot varus équin.

In France, one child in every 800 is born with talipes equinovarus. This congenital deformity of the foot prevents the flexion and extension of the ankle. Follow-up by a psychologist is essential during the care of a child with this condition, in parallel with functional rehabilitation by the masseur-physiotherapist.

Steenbeek Brace: Patterns of Wear.

UNLABELLED: Steenbeek foot abduction brace (SFAB) is an essential orthotic for maintaining correction in congenital talipes equinovarus treated with Ponseti method. As the brace is used up to 3 to 4 years of age, we examined the brace wear pattern according to a child's development and age. We studied 100 SFABs that were rendered unusable or returned by parents due to advanced brace wear. SFABs returned due to other reasons such as foot outgrowing shoe size were excluded. Each part of the brace (outer sole, insole, upper leather, abduction bar, shoe laces) was carefully inspected to observe any pattern of damage. We grouped the pattern of brace wear as per the probable causative factors into 3 broad categories: due to general use in all age groups, sitters and crawlers, and walking children. Shredded tongue, elongated/torn shoelace hole, peeled paint of metal abduction bar, shredded outer sole, and frayed shoelace were due to general use. Due to sitting and crawling with the brace on, shoe wore on its anteromedial, anterolateral, and posterolateral parts at the junction of the upper leather and outer sole. The commonest area of shoe wear in walkers was the abduction bar, which either broke from the welded junction between bar and metal or was bent at midpoint. The SFAB wear pattern was related to the age of the child and his/her activities. The reusability of the brace can probably be extended with simple improvisations and instructing parents about the correct use of the brace. LEVELS OF EVIDENCE: Prognostic, Level IV: Case series.

Feasibility and barriers of treating clubfeet in four countries.

PURPOSE: The purpose of this study was to elucidate why neglected clubfeet still exists despite the availability of a highly (cost)-effective treatment-the Ponseti treatment. METHODS: A qualitative and partly quantitative study with semi-structured interviews was conducted in four countries: the Netherlands, South Africa, Argentina and Indonesia with both caregivers, mostly parents, of children with clubfoot and practitioners treating clubfoot. The topics discussed with the caregivers (n = 51) were the conceptions of the cause of clubfeet, received information, accessibility, financial aspects, and social stigma. With the practitioners (n = 11) the focus of the interviews was the treatment protocol and finance. RESULTS: Several barriers towards the start of the treatment were highlighted. At all places treatment was financed by the government, insurance or charity. Nevertheless, the cost of transport and missed working days formed a barrier, although there is a large difference between and within countries. Poverty, long travel duration, and beliefs of supernatural causes for the clubfoot result in delay in the start of treatment. CONCLUSION: These are problems we need to address when making effective treatment available for every child to diminish the burden of neglected clubfoot; especially accessible clinics in rural areas can be a good alternative to highly specialized hospitals in large cities. We as a community should try to find and overcome the barriers to treat these patients, because we have a relatively easy and highly cost-effective treatment option which can be given by trained non-physicians supervised by an interested medical doctor.

Bilateral clubfeet are highly correlated: a cautionary tale for researchers.

BACKGROUND: Congenital talipes equinovarus, or clubfoot, is a common pediatric orthopaedic condition of unknown origin. In many clubfoot clinical trials, interventions are assigned to a patient, but response to treatment is assessed separately in each foot. Trials commonly report x patients with y feet where y is greater than x (eg, 35 patients with 56 feet). However, common statistical tests assume that each data point is independent. Although data from unilateral cases of clubfoot are independent, it is unknown if each foot of patients with bilateral clubfeet are correlated. QUESTIONS/PURPOSES: The purpose of this study was to assess the correlation in the feet of patients with bilateral clubfeet by (1) evaluating the degree of severity between lower limbs of each patient with bilateral clubfeet at baseline; (2) determining if right and left feet of each patient responded to intervention in the same way; (3) determining the proportion of bilateral relapse; and (4) determining the proportion of right and left feet which required the same intervention to correct bilateral relapse. METHODS: We performed a chart review of the records of 33 patients with bilateral clubfeet (66 feet). Baseline severity was assessed using the Pirani score. The number of Ponseti serial casts to correct the deformity, the proportion of patients who underwent bilateral Achilles tenotomy, the proportion of bilateral relapse, and the treatment to correct bilateral relapse were examined. RESULTS: The degree of severity between right (Pirani score mean, 5.2; SD, 0.8) and left (Pirani score mean, 5.2; SD, 0.5) feet for each patient at baseline was highly correlated (r=0.76, p<0.001). Response to intervention between lower limbs was highly correlated for the number of Ponseti casts required for initial correction (right mean, 5.2, SD, 1.1; left mean, 5.2, SD, 1.3) (r=0.89, p<0.001) and the proportion of patients who underwent bilateral Achilles tenotomy (right, 17/18; left, 16/18) (r=0.94, p<0.001). In the nine patients who experienced relapse, eight experienced bilateral involvement. In all cases of bilateral relapse, the right and left foot of each patient required the same intervention to correct the relapse. CONCLUSIONS: In patients with bilateral clubfeet, baseline severity, response to initial Ponseti treatment, Achilles tenotomy, and relapse outcomes were highly correlated in the right and left feet of each patient. Pooling clinical results of patients who present with bilateral clubfeet is statistically inappropriate, since results in two limbs of the same patient do not represent independent observations. These results support analogous work in other specialties suggesting that patients with bilateral presentations should not be analyzed as independent data points. LEVEL OF EVIDENCE: Level IV, therapeutic study. See the Instructions for Authors for a complete description of levels of evidence.

[Clubfoot associated with tibial and fibular hemimelia]. / Der Klumpfuß bei tibialer und fibularer Hemimelie.

AIM: Clubfoot is rarely associated with tibial or fibular hemimelia. Treatment is complex and in most of the cases extensive surgery is required. At present experience with Ponseti casting is limited. We describe casting and surgical treatment of 10 clubfeet associated with tibial and fibular hemimelia. MATERIAL AND METHOD: Between 1.1.2004 and 31.12.2009 398 clubfeet were treated with casting in our institution. In the same period 10 clubfeet were associated with fibular or tibial hemimelia. Treatment started in 9 clubfeet with Ponseti manipulation and casting. We used the classification of Weber for tibial hemimelia and the Kalamchi-Achterman classification and Paley classification for fibular hemimelia. Data of all patients were prospectively documented and the result of the foot deformity was evaluated before a first lengthening procedure. Documentation included patient data, associated foot pathologies, surgical procedures, functional results. Functional results were evaluated before the first lengthening procedure started. RESULTS: Three patients had tibial hemimelia, two Weber type 1, one Weber type 2, one Weber type 3. five patients had fibular hemimelia, Paley type IV or Kalamchi-Achterman Type IA. One child had bilateral fibular hemimelia. The prospective leg length discrepancy ranged from 3.2 cm to 14 cm. Four feet had initially a successful treatment with casting. In a type 2 according to Weber we performed an ankle reconstruction procedure to correct tibiofibular diastases. Four feet underwent PMR. We had four relapses. Two equinus relapses were treated with a posterior release. Two severe relapses were finally corrected with resection of the coalition and midfoot osteotomies. In a Weber type 3 case a complex reconstruction was performed using an Ilisarov and a TSF frame. Functional results showed in a mean follow-up of 42.2 months (24-72 months) a dorsiflexion between 5 and 20° (Ø 7.7°) and a plantarflexion between 10 and 40° (Ø 26.1°). CONCLUSION: Treatment of clubfoot associated with tibial or fibular hemimelia with the Ponseti technique is limited because of complex hindfoot deformities including tarsal coalitions. Nevertheless treatment after birth starts with casting. Only mild cases of hemimelia without coalition can be corrected with the Ponseti technique. In a case of tibiofibular diastasis successful casting is possible, but extensive surgery is often necessary. In more severe cases we do not recommend casting. In these cases surgical treatment, including posteromedial release, osteotomies for the hindfoot, resection of coalitions or complex osteotomies with Ilisarov or TSF frame is the treatment of choice.

Development of a surrogate biomodel for the investigation of clubfoot bracing.

Congenital talipes equinovarus (clubfoot) is a complex deformity of the lower extremity and foot occurring in 1/1000 live births. Regardless of treatment, whether conservative or surgical, clubfoot has a stubborn tendency to relapse, thus requiring postcorrection bracing. However, to date, there are no investigations specifically focused on clubfoot bracing from a bioengineering perspective. This study applied engineering principles to clubfoot bracing through construction of a surrogate biomodel. The surrogate was developed to represent an average 5-year-old human subject capable of biomechanical characteristics including joint articulation and kinematics. The components include skeleton, articulating joints, muscle-tendon systems, and ligaments. A protocol was developed to measure muscle-tendon tension in resting and braced positions of the surrogate. Measurement error ranged from 1% to 6% and was considered variance due to brace and investigator. In conclusion, this study shows that surrogate biomodeling is an accurate and repeatable method to investigate clubfoot bracing. The methodology is an effective means to evaluate wide ranging brace options and can be used to assist in future brace development and the tuning of brace parameters. Such patient-specific brace tuning may also lead to advanced braces that increase compliance.

[Mid-term results of idiopathic clubfeet treated with the Ponseti method]. / Mittelfristige Ergebnisse der Behandlung des idiopathischen Klumpfußes mit der Ponseti-Methode.

AIM: The Ponseti method is accepted worldwide for the treatment of congenital clubfoot. We report about our experience in a 7-year period. The purpose of the study was to evaluate the history of well treated feet between primary correction and the age of 5-6 years with relapse rate and functional results. MATERIAL AND METHOD: Between 1.1.2004 and 31.12.2005 we treated 71 patients with 102 idiopathic clubfeet with the Ponseti method. All patients were prospectively evaluated. We used the Pirani score. The patients' results were documented when the children started to walk and before primary school. The results were compared and statistically evaluated. We used the McKay score and measured the talocalcaneal angle on lateral and a. p. radiographs. RESULTS: 89 % clubfeet were successful treated with the Ponseti method. At walking age plantar flexion was between 30° und 50° (∅ 42°) and dorsiflexion between 5° and 30° (∅ 25°). Before primary school plantar flexion was between 30° and 50° (∅ 37,8°) and dorsiflexion between 0° and 25° (∅ 13,9°). Using the McKay score we had 91 % excellent or good results. 31 % cases had surgical treatment of a relapse. In the relapse group 82 % had an excellent or good result according to the McKay score. CONCLUSION: The Ponseti method is a very effective technique to treat idiopathic clubfeet. In the first 5 to 6 years of age there is a significant loss of range of motion. The relapse rate is comparable to those of other clubfoot treatment concepts. The relapse treatment of the Ponseti technique, with recasting, tibialis anterior tendon transfer and Achilles tendon lengthening leads to good functional results.

Comprehensive review of the functional outcome evaluation of clubfoot treatment: a preferred methodology.

Treatment outcome has been a focus of interest in those who manage clubfeet. Because of a lack of a common evaluation protocol, it has become necessary to establish a universally recognized quantitative measurement to compare and better understand the treatment outcome. The outcome is not merely morphological and radiographic, but it should also include functional and quality-of-life measurements. In this article, we will outline the most commonly used methods of long-term evaluation for congenital clubfeet and recommend the data collection parameters that are most appropriate for a comprehensive functional analysis. This will begin with pretreatment classifications that are important in prognosticating the results. The physical examinations and plain radiographs in standing position are also two fundamental evaluations of clubfoot. Several outcome evaluations have been published in the literature and may be useful depending on the desired metrics. Gait analysis is an additional useful technical tool for analyzing the motion of the foot and ankle and its relation to the whole body function; pedobarography added to the dynamics of the evaluation. Functional quality-of-life questionnaires are increasing in popularity for measuring the total body functional status and the quality of life.

[Early results of congenital clubfoot using Ponseti method]. / Wczesne wyniki leczenia stopy konsko-szpotawej wrodzonej metoda Ponsetiego.

Congenital clubfoot is one of the most common congenital skeletal defects. Its aetiology remains unclear. Due to its high incidence and social consequences, the therapy of congenital clubfoot presents an important medical issue. Non-surgical treatment methods are preferred. Many publications confirmed the efficacy of the Ponseti method. The aim of this study was to present early results of congenital clubfoot treatment using the Ponseti method in a one-year follow-up. The therapy protocol was in accordance with guidelines presented by the inventor. The necessity of surgical treatment was a criterion for negative treatment outcome. One hundred and sixteen feet of 92 children were analysed. A Dimeglio-Bensahel classification was used for the evaluation of the defect advance. Seventy-one feet (61.2%) were assessed as grade II, 43 feet as grade III (37.1%) and 2 feet as grade IV deformation. No patients with grade I deformation were included into the study. A positive treatment outcome was observed for 96 feet (82.7%), whereas a negative result for the remaining 20 feet (17.3%). Our results are therefore not consistent with the literature data. It could have resulted from the too precipitate qualification for surgery by the physician and problems with compliance. The Ponseti method is an effective and less straining treatment modality of the congenital clubfoot. In most cases it allows for avoiding extensive surgery and associated complications. A necessity of wearing an orthosis and a risk treatment failure, if not worn systematically, should be emphasised. A longer follow-up period is required for complete result analysis.

Functional midterm outcome in 131 consecutive cases of surgical clubfoot treatment.

INTRODUCTION: Since introduction and widespread use of the Ponseti method in the last decade, the need for surgical treatment of clubfeet is nowadays limited to resistant cases. In the time before, surgery via dorsomedial release was a very common treatment option. METHOD: Very few long-term follow-up studies cover the outcome of surgical methods, which is particularly interesting, as clinical results rather worsen with time. In the present study, 98 children (131 clubfeet), who underwent surgical correction using the Imhauser method at the age of 4.5 months were included. Follow-up time was 8.2 years (0-11.8 years) at average. RESULTS: Data could be retrieved from 46 patients (71 feet), only 5 patients (7 feet) were lost to follow-up. The rate of relapses was high, as 47 patients (53 feet) needed surgical revision for recurrence, while clinical scores showed a good result in the Laaveg and Ponseti Score and the Foot-Function-Index. Isokinetic testing and clinical data indicated a significant weakness of the treated foot, when compared to the healthy side in 12 patients with unilateral deformity. The presented study supports like others the issue that the clinical outcome of a surgical, posteromedial release in terms of relapses is disappointing. This fact is apparently not sufficiently reflected in the current clinical scores, which showed rather good results. CONCLUSION: As the question of evaluation methods for results of clubfoot treatment remains controversial, isokinetic testing is an easy to use alternative that provides detailed information about functional limitations and may help in reducing the need for repeated radiographic examinations.

Patient-reported outcome at 62 to 67 years of age in 83 patients treated for congenital clubfoot.

The outcome in 83 patients with congenital clubfoot was evaluated at a mean age of 64 years using three validated questionnaires assessing both quality of life (short-form (SF)-36 and EQ-5D) and foot and ankle function (American Academy of Orthopaedic Surgeons (AAOS) Foot and Ankle questionnaire). In SF-36, male patients scored significantly better than male norms in seven of the eight domains, whereas female patients scored significantly worse than female norms in two of the eight. Male patients scored better than male norms in both the EQ-5D index (p = 0.027) and visual analogue scale (VAS) (p = 0.013), whereas female patients scored worse than female norms in the VAS (p < 0.001). Both male and female patients had a significantly worse outcome on the AAOS Core Scale than did norms. There was a significant correlation for both genders between the SF-36 Physical Component Summary Score and the AAOS Core Scale. The influence on activities of daily life was limited to foot and ankle problems in all patients, and in females there was an adverse effect in physical aspects of quality of life.
