OBJECTIVE:
To evaluate the effectiveness of correcting post-traumatic equinovarus deformity using Ilizarov external fixation technique combined with limited osteotomy.
METHODS:
A retrospective analysis was conducted on clinical data from 29 patients with post-traumatic equinovarus deformity treated between July 2018 and March 2023. The cohort included 18 males and 11 females, with ages ranging from 15 to 57 years (mean, 24.3 years). All patients exhibited ankylosed ankle joints with equinovarus deformity. During surgery, external fixators were installed according to Ilizarov pinning principles, and minimally invasive osteotomy was performed at the ankle joint. Concurrently, soft tissue release was achieved via minimally invasive Achilles tendon lengthening. Postoperatively, multiplanar deformity correction was accomplished through gradual adjustment of the external fixator. The fixator was removed after bony union at the osteotomy site, followed by bracing. The surgical duration, intraoperative blood loss, fixator wear time, and complications were recorded. Postoperative outcomes included assessment of deformity correction and bony union at the osteotomy site. Functional improvement and pain relief were evaluated using pre- and post-operative scores from the American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot score and visual analogue scale (VAS) score.
RESULTS:
All 29 patients were followed up 12-24 months (mean, 18 months). The mean surgical duration was 85.6 minutes, with a mean intraoperative blood loss of 110 mL. Full deformity correction was achieved within 26-80 days (mean, 40.7 days) through progressive fixator adjustments. At correction completion, all ankles restored to a neutral or 5°-10° dorsiflexed position with plantigrade foot function. Superficial pin tract infections occurred in 3 patients (10.3%), resolved with local wound care, enhanced nursing, and oral antibiotics. No deep or systemic infections was observed. One patient sustained a calcaneal half-pin fracture due to a fall during fixator wear, but no bone fragment displacement occurred. No vascular or neurological complication was reported. Complete bony union was achieved at all osteotomy sites without nonunion. At last follow-up, the AOFAS ankle-hindfoot score improved from preoperative 42.7±8.7 to postoperative 65.7±9.3, and the VAS score decreased from preoperative 4.5±1.3 to postoperative 2.5±1.1, with significant differences ( P<0.05). Functional outcomes were rated as excellent in 14 cases, good in 13 cases, fair in 1 case, and poor in 1 case, with an excellent and good rate of 93.1%.
CONCLUSION
The progressive correction strategy combining Ilizarov external fixation technique with limited foot osteotomy effectively corrects post-traumatic equinovarus deformity while preserving soft tissue integrity. This method is associated with minimal, largely controllable complications and achieves alignment stability and fusion outcomes comparable to traditional open surgery, making it an effective treatment for complex foot and ankle deformities.

OBJECTIVE:
To summarize the methods of ankle hinge position design in the correction of clubfoot deformity by Ilizarov method, and to explore its application value in the prevention of ankle dislocation.
METHODS:
A retrospective study was conducted including 28 patients with rigid clubfoot deformity (34 feet) who met the selection criteria and admitted between September 2021 and December 2024. There were 19 males and 9 females with an average age of 31.8 years (range, 19-47 years). According to Dimeglio classification, there were 21 feet of degree Ⅲ and 13 feet of degree Ⅳ. The causes were traumatic sequelae in 9 cases, congenital foot deformity in 15 cases, spina bifida sequelae in 1 case, peripheral neuropathy in 1 case, and cerebral palsy sequelae in 2 cases. The malformation lasted from 6 to 46 years, with an average of 29.3 years. All patients were treated with Ilizarov circular external fixator, and the hinge position of ankle joint was planned according to the standard lateral X-ray film of foot and ankle and the principle of Ilizarov limb deformity correction center of rotation angulation (CORA) before operation. The 2008 International Clubfoot Study Group (ICFSG) scoring system was used to evaluate the efficacy.
RESULTS:
The deformity of rigid clubfoot was completely corrected in all patients, and the patients could walk with plantar weight-bearing, and the ankle weight-bearing walking significantly improved when compared with that before operation. There was no complication such as ankle dislocation, talus impact or extrusion, local skin necrosis, needle tract infection, or numbness of extremities during the correction process. All patients were followed up 5-39 months, with an average of 18.1 months. At last follow-up, according to the ICFSG scoring system, 23 feet were excellent, 10 feet were good, and 1 foot was fair, and the excellent and good rate was 97%.
CONCLUSION
Designing the position of the ankle hinge according to the principle of CORA can effectively avoid ankle dislocation, talus impingement, tibiotalar joint extrusion, and other ankle adverse events in the process of correcting clubfoot deformity, which has good application value in clinical practice.

OBJECTIVE:
To explore the biomechanical characteristics and clinical application effects of three-dimensional (3D) printed osteotomy guide plate combined with Ilizarov technique in the treatment of rigid clubfoot.
METHODS:
A retrospective analysis was performed on the clinical data of 11 patients with rigid clubfoot who met the inclusion criteria and were admitted between January 2019 and December 2024. There were 6 males and 5 females, aged 21-60 years with an average of 43.2 years. Among them, 5 cases were untreated congenital rigid clubfoot, 4 cases were recurrent rigid clubfoot after previous treatment, and 2 cases were rigid clubfoot due to disease sequelae. All 11 patients first received slow distraction using Ilizarov technique combined with circular external fixator until the force lines of the foot and ankle joint were basically normal. Then, 1 male patient aged 24 years was selected, and CT scanning was used to obtain imaging data of the ankle joint and foot. A 3D finite element model was established and validated using the plantar stress distribution nephogram of the patient. After validation, the biomechanical changes of the tibiotalar joint under the same load were simulated after triple arthrodesis and fixation. The optimal correction angle of the hindfoot was determined to fabricate 3D-printed osteotomy guide plates, and all 11 patients underwent triple arthrodesis using these guide plates. The functional recovery was evaluated by comparing the American Orthopaedic Foot and Ankle Society (AOFAS) score, International Clubfoot Study Group (ICFSG) score, and 36-Item Short Form Survey (SF-36) score before and after operation.
RESULTS:
Finite element analysis showed that the maximum peak von Mises stress of the tibiotalar joint was at hindfoot varus 3° and the minimum at valgus 6°; the maximum peak von Mises stress of the 3 naviculocuneiform joints under various conditions appeared at lateral naviculocuneiform joint before operation, and the minimum appeared at lateral naviculocuneiform joint at neutral position 0°; the maximum peak von Mises stress of the 5 tarsometatarsal joints under various conditions appeared at the 2nd tarsometatarsal joint at hindfoot neutral position 0°, and the minimum appeared at the 1st tarsometatarsal joint at valgus 6°. Clinical application results showed that the characteristics of clubfoot deformity observed during operation were consistent with the preoperative 3D reconstruction model. All 11 patients were followed up 8-24 months with an average of 13.1 months. One patient had postoperative incision exudation, which healed after dressing change; the remaining patients had good incision healing. All patients achieved good healing of the osteotomy segments, with a healing time of 3-6 months and an average of 4.1 months. At last follow-up, the AOFAS score, SF-36 score, and ICFSG score significantly improved when compared with those before operation ( P<0.05).
CONCLUSION
The 3D-printed osteotomy guide plate combined with Ilizarov technique has favorable biomechanical advantages in the treatment of rigid clubfoot, with significant clinical application effects. It can effectively improve the foot function of patients and achieve precise and personalized treatment.

OBJECTIVE:
To investigate the effectiveness of applying a standardized rehabilitation process in correction of adult clubfoot with the Ilizarov technique.
METHODS:
Thirty-eight adult patients who underwent orthopedic treatment with Ilizarov technique for clubfoot between August 2022 and December 2024 were retrospectively analyzed. The patients were divided into a study group and a control group with 19 cases in each group according to the different rehabilitation management processes and methods. The differences in baseline data such as gender, age, side, and preoperative Holden walking function grading between the two groups were not significant ( P>0.05). In both groups, most of the clubfoot deformities were surgically corrected first, and the residual deformities were corrected by dynamic slow retraction with Ilizarov ring-type external fixation frame. The study group adopted standardized rehabilitation process management mode, including preoperative lower limb muscle strength training, postoperative pain and swelling management, weight-bearing management, gait and lower limb stability training. The control group adopted the conventional postoperative rehabilitation management mode. The occurrence of complications was recorded, including pin tract infection, ankle stiffness and pain, and deformity recurrence. Holden walking function grading was used to evaluate the walking ability of the patients. Clinical efficacy was evaluated by the QIN Sihe Deformity Correction Disability Repair and Functional Reconstruction Postoperative Efficacy Evaluation Scale. Patient satisfaction was evaluated by Likert score.
RESULTS:
Patients in both groups successfully completed surgery and rehabilitation and were followed up. The follow-up time ranged from 8 to 29 months, with a mean of 18.5 months. Among them, the follow-up time was (18.8±5.5) months in the study group and (18.2±5.7) months in the control group, and the difference between groups was not significant ( t=0.316, P=0.754). The postoperative incidences of pin tract infection, ankle stiffness and pain, and deformity recurrence in the study group were 10.53%, 5.26%, and 5.26%, respectively, and in the control group were 21.05%, 36.84%, and 15.79%, respectively. And the difference between groups in the incidence of ankle stiffness and pain was significant ( P=0.042). At last follow-up, both groups showed an improvement in Holden walking function grading compared to preoperative levels ( P<0.05), and the grading of the study group was significantly higher than that of the control group ( P=0.006). According to the QIN Sihe Deformity Correction Disability Repair and Functional Reconstruction Postoperative Efficacy Evaluation Scale, the grade difference between groups was not significant ( P=0.089), and the excellent and good rates of clinical efficacy in study group and control group were 89.47% (17/19) and 73.68% (14/19), respectively. Patient satisfaction in study group was significantly better than that in control group ( P=0.036).
CONCLUSION
Standardized rehabilitation process can effectively promote the postoperative functional recovery of adult clubfoot treated with Ilizarov technique, reduce the risk of complications and improve effectiveness.

5.Results of Ponseti Casting for Clubfoot in a Tertiary Public Hospital
Ilian Dominiq D. Eusebio ; Carlo Emmanuel J. Sumpaic
Acta Medica Philippina 2021;55(3):315-321
INTRODUCTION: Congenital talipes equinovarus (CTEV), also called clubfoot, is one of the most common orthopedic congenital anomalies. However, there is no formal study of the condition here in the Philippines, and data is sparse regarding the epidemiology, treatment, and outcomes in similar third-world countries.
METHODS: Retrospective review of data of clubfoot patients seen at the Philippine General Hospital (PGH) Clubfoot Clinic from 2006 up to the present.
RESULTS: Records from 75 patients treated at the PGH Clubfoot Clinic from 2010-2016 were reviewed. Idiopathic clubfoot comprised 76% of the patients, while syndromic clubfoot comprised 24%. A good outcome of the Ponseti method was seen in 82% and 88% of the idiopathic and syndromic clubfoot patients, respectively. Idiopathic clubfoot cases that had good outcomes required an average of 11.84 casts to tenotomy or bracing, which was not statistically significant compared to 9.55 average sessions for syndromic clubfoot (p=0.21). The initial Pirani scores for both cases were not significantly different (p=0.95). Idiopathic cases with poor outcomes needed less casting sessions (4.45) because the decision to operate was made early. Age was not found to significantly affect the outcome of treatment for idiopathic clubfoot (p=0.20) and syndromic clubfoot (p=0.64).
CONCLUSION: Ponseti casting was found to be effective in treating both idiopathic and syndromic clubfoot patients. The number of sessions did not differ significantly between the two.

Acta Medica Philippina 2021;55(3):322-327
OBJECTIVE: This study aimed to quantitatively define outcomes of corrective surgery in children with various foot deformities.
METHODS: We used a retrospective, nonrandomized design. All pediatric patients who underwent pre and post-operative gait analysis and corrective surgery were included. Outcome measures included quantitative gait analysis with temporospatial and kinematic parameters, the Gait Deviation Index, Gillette FAQ, and Hoffer’s criteria.
RESULTS:. Five patients with neurogenic and idiopathic deformities underwent corrective surgery at the Philippine General Hospital from 2015 to 2017. Comparison of gait pre and postoperatively show promising outcomes, with improvement in GDI and FAQ levels, despite some of the patients’ need for braces.
CONCLUSIONS: Quantitative gait analysis is a suitable method for evaluating surgical outcomes for foot deformity correction. It can be used in combination with functional outcome measures and clinical examination to give an overall picture of a patient’s walking ability.

PURPOSE: Several radiologic reference lines have been used to evaluate individuals with a clubfoot but there is no consensus as to which is most reliable. The aim of this study was to identify which radiologic parameters have relevance to the predictability of additional surgery after Ponseti casting on clubfoot and the effect of clubfoot treatments that contain Ponseti casting and additional surgery. MATERIALS AND METHODS: A total of 102 clubfeet (65 patients, 37 bilateral) were reviewed from 2005 to 2013. The patients were divided into two groups (Group A, those for whom the result of the Ponseti method was successful and did not require additional surgery; and Group B, those for whom the result of the Ponseti method was unsuccessful and required additional surgery), and the following parameters were measured on the plain radiographs: i) talo-calcaneal angle on the anteroposterior and lateral view, ii) talo-1st metatarsal angle on the anteroposterior view, and iii) Tibio-calcaneal angle on the lateral view with the ankle full-dorsiflexion state. Each radiograph was reviewed on two separate occasions by one orthopedic doctor to characterize the intra-observer reliability, and the averages were analyzed. Next, 20 cases were chosen using a random number table, and two orthopedic doctors measured the angle separately to characterize the inter-observer reliability. RESULTS: Groups A and B included 73 clubfeet (71.6%) and 29 clubfeet (28.4%), respectively. The initial talo-calcaneal angle and tibio-calcaneal angle in the lateral view were significantly different among the groups. In addition, inter- and intra-observer biases were not detected. The talo-1st metatarsal angle on the anteroposterior view and tibio-calcaneal angle on the lateral view were significantly different after treatment in both groups. CONCLUSION: Congenital clubfeet treated with the Ponseti method showed successful results in more than 70% of patients. The initial talo-calcaneal angle and tibio-calcaneal angle on the lateral view were the radiologic parameters that could predict the need for additional surgical treatments. The talo-1st metatarsal angle on the anteroposterior view and tibio-calcaneal angle on the lateral view could effectively evaluate the changes in clubfoot after treatment.

PURPOSE: To investigate the effect of intramuscular Botulinum toxin type A (BoNT-A) injection on gait and dynamic foot pressure distribution in children with spastic cerebral palsy (CP) with dynamic equinovarus foot. MATERIALS AND METHODS: Twenty-five legs of 25 children with CP were investigated in this study. BoNT-A was injected into the gastrocnemius (GCM) and tibialis posterior (TP) muscles under the guidance of ultrasonography. The effects of the toxin were clinically assessed using the modified Ashworth scale (MAS) and modified Tardieu scale (MTS), and a computerized gait analysis and dynamic foot pressure measurements using the F-scan system were also performed before injection and at 1 and 4 months after injection. RESULTS: Spasticity of the ankle plantar-flexor in both the MAS and MTS was significantly reduced at both 1 and 4 months after injection. On dynamic foot pressure measurements, the center of pressure index and coronal index, which represent the asymmetrical weight-bearing of the medial and lateral columns of the foot, significantly improved at both 1 and 4 months after injection. The dynamic foot pressure index, total contact area, contact length and hind foot contact width all increased at 1 month after injection, suggesting better heel contact. Ankle kinematic data were significantly improved at both 1 and 4 months after injection, and ankle power generation was significantly increased at 4 months after injection compared to baseline data. CONCLUSION: Using a computerized gait analysis and foot scan, this study revealed significant benefits of BoNT-A injection into the GCM and TP muscles for dynamic equinovarus foot in children with spastic CP.

Journal of Korean Foot and Ankle Society 2016;20(1):36-38
Tarsal coalition is an abnormal union between two or more bones of the hind- and mid-feet, which can occur at various rates from cartilaginous to osseous union. Talonavicular coalition is reported less frequently than calcaneonavicular or talocalcaneal coalition and has been associated with various abnormalities, including symphalangism, clinodactyly, ray anomaly, clubfoot, other tarsal coalitions, and a ball-and-socket ankle joint. Patients with talonavicular coalitions are usually asymptomatic and rarely require surgical treatment. We review the literature and report on a case of 59-year-old male patient with talonavicular coalition.
