Abstract
PURPOSE The treatment of infantile Blount's disease usually includes surgical correction, but high recurrence is still a problem regardless of the procedure. We conducted a cross-sectional study of severely neglected infantile Blount's disease treated with acute correction and simultaneous hemiepiphysiodesis of lateral proximal tibia physis. In this study, we aimed to observe the complication and recurrence. METHODS This research is an analytical study with a cross-sectional design using retrospective data collection and total sampling. The subjects were patients with neglected infantile Blount's disease treated from 2018 to 2023 in our institution. Follow-up was conducted in 6, 12, 24, and 36 months. RESULTS A total of 25 legs from twenty patients were recorded. We observed three legs (12.0%) had recurrence. No neurovascular complications and infections were observed. All subjects had significant postoperative improvement of TFA (mean 6.8 ± 0.730 valgus), Drennan angle, MPTA, MTPD, JLCA, and ligamentous laxity grading (p < 0.001). Lower than 5° postoperative valgus overcorrections and preoperative physeal bar were significant factors in patients with recurrence (p = 0.020 and p = 0.010). There was no significant increase in leg-length discrepancy during follow-up (p = 0.052). There were no significant differences between age, BMI, preoperative TFA, pre- and postoperative Drennan angle, MPTA, MTPD, JLCA, Langenskiöld stages, and length of follow-up in patients with recurrence and not. CONCLUSION Acute correction with simultaneous hemiepiphysiodesis of lateral proximal tibia physis is an effective technique to prevent deformity recurrence in neglected infantile Blount's disease, provided that the postoperative TFA is more than 5° of valgus and no evidence of physeal bar in the preoperative radiograph.

Abstract
This study aimed to evaluate the clinical and radiological outcomes of surgical intervention involving acute medial hemi-plateau elevation and metaphyseal osteotomy with internal fixation and growth modulation for late-stages Blount's disease. A retrospective analysis was conducted on consecutive patients with late-stages infantile tibia vara between 2014 and 2020. Inclusion criteria consisted of children aged 8 years and older with Blount's disease with Langenskiold stage IV, V or VI, tibia vara more than 30*, medial plateau depression angle (MPDA) exceeding 25* and knee instability with a minimum follow-up period of 3 years. Patients with Limb length discrepancy greater than 5 cm were excluded. Data collection included assessments of age, weight, disease stage, clinical tibiofemoral angle (TFA), mechanical medial proximal tibial angle (mMPTA), MPDA, tibial torsion and knee instability. Functional outcomes were evaluated using modified Pediatric Outcome Data Collection Instruments (PODCI) scores. The study included 5 children with 8 affected limbs. Among them, three children with five limbs had recurrent deformities after previous surgeries. All cases showed significant improvements in TFAs, mMPTA, tibial torsion, knee instability and modified PODCI scores. Complications included 4 cases of superficial infections, 1 intra-articular fracture, 2 minor screw breakage and 2 on-table under correction. Surgical intervention involving acute Single-stage medial hemi-plateau elevation and metaphyseal osteotomy leads to satisfactory outcomes in late-stages Blount's disease among older children. It is crucial to achieve proper correction of all deformity components during surgery, with epiphysiodesis on the lateral side to prevent further recurrence. Continuous follow-up until skeletal maturity is essential for optimal results.

Recurrence and Complication Rates of Surgical Treatment for Blount's Disease in Children: A Systematic Review and Meta-Analysis. J Clin Med 2023; 12:6495. [PMID: 37892633 PMCID: PMC10607610 DOI: 10.3390/jcm12206495] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2023] [Revised: 10/05/2023] [Accepted: 10/10/2023] [Indexed: 10/29/2023] Open
Abstract
BACKGROUND Blount's disease is a growth disorder of the proximal tibia that causes progressive genu varum in children. Surgical treatment is recommended if the deformity worsens, but which intervention is best remains controversial. This study aims to identify factors influencing outcomes and determine the most effective surgical approach. METHODS A systematic review was conducted of studies published before January 2022. RESULTS In total, 63 retrospective studies with CEBM IIIb/IV levels were included (1672 knees in 1234 patients). The most commonly reported treatment was acute correction via osteotomy (47%), followed by hemiepiphysiodesis (22%) and gradual correction (18%). Combined procedures were reported in 13% of cases. The overall recurrence rate was 18%, with a significant difference when comparing the recurrence rates after gradual correction with those after hemiepiphysiodesis (7% and 29%, respectively). Major complications beyond recurrence were observed in 5% of cases. A meta-analysis of the available raw data showed a significantly increased recurrence rate (39%) among treated children who were between 4.5 and 11.25 years of age and were followed for a minimum follow-up of 2.5 years. CONCLUSIONS Overall, poor evidence with which to establish an optimal treatment for Blount's disease was found. This study remarked on the need for early diagnosis, classification, and treatment of infantile tibia vara, since a significant rate of recurrence was found in neglected cases.

Abstract
Aim To evaluate the results in terms of correction and complications from gradual correction with a computer-assisted hexapod circular external fixator in a mixed cohort of children with Blount's disease. Materials and methods A retrospective review was performed of the correction and complications of 19 children (25 limbs) with recurrent infantile (IBD) and late-onset Blount's disease (LOBD) treated by gradual correction with a hexapod external fixator. The correction was measured by the medial proximal tibial angle (MPTA), anatomic posterior proximal tibial angle (aPPTA) and anatomic tibio-femoral angle (TFA). Obesity was present in 76% (19/25) of cases. Fifteen limbs were classified as infantile Blount's disease and 10 limbs as late-onset Blount's disease. The mean age was 12.5 years (range 7–17 years). Results The mean pre-operative MPTA of 59° (SD 13°, range 33–79°) was corrected to a mean of 86° (SD 5°, range 77–93°). The mean pre-operative aPPTA of 64° (SD 14°, range 33–84°) was corrected to 79° (SD 6°, range 70–90°). The median pre-operative rotation of 15° internal rotation was corrected to normal (0–15° of external rotation). Eight out of 25 limbs had severe deformities with varus or procurvatum greater than 40° or both. The mean pre-operative TFA of 28° varus (SD 13°, range 4–53°) was corrected to 1.8° valgus (SD 6°, range 14° varus to 13° valgus). The median follow-up was 19 months (range 6–67 months). The alignment after correction was “good” in 55% (11/20), “acceptable” in 35% (7/20) and “poor” in 10% (2/20). The median duration for correction was 16 days (IQR 11–31 days, range 7–71 days). The median number of prescribed correction programmes was 1 (IQR 1–2, range 1–5). The mean total time in the frame was 136 days (SD 34 days, range 85–201 days). All patients developed minor pin track infections that resolved with oral antibiotics (Category 1 complications). Four patients developed complications that necessitated modification of the treatment plan (Category 2 complications). In two cases, treatment objectives could not be achieved (Category 3 complications). Two patients treated before skeletal maturity developed recurrent genu varum. Conclusion Gradual correction with a computer-assisted hexapod external fixator may be a useful technique for correcting recurrent IBD or LOBD even in children with severe deformities. The results of gradual correction were similar in the two groups. While complications occur, most can be mitigated by timely intervention during the correction phase of treatment. Recurrence remains a concern if correction is performed before skeletal maturity. Level of evidence 4. How to cite this article Mare PH, Marais LC.

Abstract
BACKGROUND Late-presenting or recurrent infantile Blount disease (IBD) is characterized by knee instability because of medial tibial plateau depression, multiplanar proximal tibial deformity, and potential distal femoral deformity. The surgical treatment strategy includes medial elevation osteotomy to stabilize the knee, together with proximal tibial osteotomy to correct alignment, and lateral epiphysiodesis to prevent a recurrence. This study's primary aim was to describe the clinical outcomes of medial elevation osteotomy for the management of late-presenting and recurrent IBD. METHODS The authors reviewed the records of 48 children (64 limbs) who had medial elevation osteotomies and lateral epiphysiodesis, combined with proximal tibial realignment in 78% (50/64) of cases in the same setting. IBD was bilateral in 33% (16/48), 77% (37/48) were female individuals, and 42% (20/48) were obese. RESULTS The mean age at surgery was 8.6 years (SD, 1.6; range, 5.8 to 12.8). The mean preoperative tibiofemoral angle (TFA) was 28±11 degrees (8 to 55 degrees), and the mean angle of depression of the medial plateau (ADMP) was 49±8 degrees (26 to 65 degrees). Distal femoral valgus was present in 27% (17/62) and varus in 10% (6/62) children. At a median follow-up of 3.2 years (range, 1 to 6.2 y), the median TFA was 1-degree valgus (interquartile range, 7-degree varus to 5-degree valgus), whereas the ADMP was corrected to 25±8 degrees (8 to 45 degrees). Obesity was associated with more severe deformity as measured by TFA (P<0.001) but did not affect the extent of medial plateau depression (P=0.113). The good or excellent alignment was achieved in 75% (47/63) limbs. Obesity was associated with an increased risk of recurrence [odds ratio (OR), 5.21; 95% CI, 1.26-21.63; P=0.023]. Age at the surgery or previous surgery was not associated with recurrence (OR, 1.29; 95% CI, 0.88-1.88; P=0.195 and OR, 1.22; 95% CI, 0.36-4.17; P=0.746). Obesity and residual instability were associated with an increased risk of poor alignment at the latest follow-up (OR, 3.24; 95% CI, 1.02-10.31; P=0.047 and OR, 1.21; 95% CI, 1.05-1.40; P=0.008). CONCLUSION Late-presenting or recurrent IBD is a surgical challenge. Obesity is associated with more severe deformity. Medial elevation osteotomy combined with lateral proximal tibial epiphysiodesis and metaphyseal tibial realignment osteotomy will result in restoration of lower limb alignment in a high proportion of cases. The recurrent deformity may be the result of failed epiphysiodesis. Obesity and residual instability are associated with an increased risk of poor alignment. Although complications are rare, surgical measures to decrease risk should be followed. LEVEL OF EVIDENCE Level IV.

Abstract
The treatment of Blount's disease has historically remained controversial. All the described techniques for its treatment have their own advantages and disadvantages, and no consensus has been reached on a single surgical approach. The aim of this report is to share the early results of a combination technique in which we have collated three well-known surgical steps in one procedure. This combined procedure is indicated for severe and recurrent cases. Our ‘three-in-one’ technique combines an intra-epiphyseal plateau elevating osteotomy with a tibial metaphyseal osteotomy and a lateral tibial temporary hemi-epiphysiodesis. We also report initial results of three limbs in two patients who were treated using this technique. The first case was that of an adolescent with severe left Blount's disease (Langenskiold stage IV) and a lateral thrust. The second case was that of bilateral severe infantile Blount's disease (Langenskiold stage V) and the infant had a lateral thrust. All measurements remarkably improved in both patients during the post-surgical assessment. The limb length discrepancy was 0.6 cm in the first case and 0.5 cm in the second. The preoperative internal tibial rotation and lateral thrust were corrected spontaneously. No complications were recorded in either patient. The three-in-one technique is a safe and versatile surgical approach that can be used in severe, refractory, and recurrent cases of open physis. Furthermore, it can potentially solve the problems of lateral thrust and internal tibial rotation. More cases should be studied before we can endorse the safety and effectiveness of this technique.

Abstract
BACKGROUND Blount disease is a disorder of the posteromedial proximal tibial physis which causes a progressive varus, procurvatum, and internal rotation deformity of the tibia. Untreated, it can cause significant limb malalignment. The goal of this study is to evaluate the results of correction of Blount disease using types of external fixation. METHODS We conducted a retrospective review of 41 patients (51 limbs) who underwent correction of Blount disease with an Ilizarov external fixator or a Taylor spatial frame (TSF) by a single surgeon. The medial proximal tibial angle (MPTA), mean axis deviation (MAD), posterior proximal tibial angle, and joint line congruence angle (JLCA) were measured on radiographs preoperatively, at frame removal and at final follow-up. RESULTS The average age at treatment was 9.6 years old, with a mean follow-up time of 34 months. Mean preoperative MPTA, MAD, and JLCA were significantly improved at the time of frame removal as well as at final follow-up with no significant changes in correction between the time of frame removal and final follow-up. There was no difference in MPTA and MAD in patients treated with an Ilizarov frame versus a TSF. MPTA, MAD, and JLCA all significantly improved regardless of the underlying diagnosis (infantile vs. adolescent Blount disease) or history of prior surgical intervention. The most common complication was superficial pin-site infection. CONCLUSIONS Both Iliazarov and TSF are viable treatment options for infantile and adolescent Blount disease, with the ability to significantly improve both the limb mechanical axis and the mechanical axis of the affected tibia. Correction can be attained regardless of whether patients have previously failed surgical intervention. LEVEL OF EVIDENCE Level III-retrospective comparative study.

Abstract
PURPOSE The purpose of this study is to evaluate a surgical technique that aims to address the multi-planar deformities occurring in early onset Blount's disease. METHODS Seven patients (eight lower limbs) with early onset Blount's disease were treated with a surgical technique that used an external fixator to simultaneously address all aspects of deformity. Presenting radiographic parameters including mechanical axis deviation (MAD), lateral distal femoral angle (LDFA), medial proximal tibial angle (MPTA) and medial plateau angle (MPA) were compared with final follow-up and the unaffected limb. Data was also collected on surgical complications and functional outcomes. RESULTS After a mean interval of 4.6 years (2.2 to 9), the MAD of the affected limb improved from 4.85 cm to 1.88 cm, MPTA from 43.58° to 75.46° and MPA from 43.41° to 20.71°. The mean time in the external fixator was 5.6 months (3.5 to 10.4). Recurrence was noted in three patients; two had evidence of nerve injury and one patient had premature fibular consolidation. CONCLUSION The surgical technique described in this study has attempted to address the complex multiaxial deformity that is encountered in Blount's disease. It identifies difficulties and limitations in developing a comprehensive surgical protocol and highlights complications associated with this approach.

Abstract
Background: Taylor Spatial Frame (TSF) is a modern circular external fixator that, using a virtual hinge, is able to correct six axis deformities simultaneously. Despite the growing popularity of this method, few reports exist about its use in children and adolescents. To evaluate the effectiveness of TSF in correcting multiplanar deformities in patients with open physis, we reviewed the results of treatment in children who had at least two planes deformities of lower limbs. Methods: Over a period of 8 years, we treated 51 patients, 40 boys, 11 girls, with a mean age of 12.4 years (range, 2-16 years). All patients had open physis at the time of the TSF application. All patients had at least two deformities (angular and/or rotational). Fifty-five osteotomies (11 femoral, 44 tibial) were performed. Patients were divided into four groups: 13 with post-traumatic malunions, 18 with tibia vara, six with rickets, and 14 with miscellaneous deformities. Correction goal was determined as correction of deformities to population-average parameters of the lower limbs in frontal and sagittal views and normal mechanical axis deviation. Results: Correction goal was achieved in all except one patient; four patients had recurrence of deformities post-operatively and were re-operated. Most common complications were pin tract infection (20 patients), delayed union (2), regenerate translation (1), post-removal femoral fractures (2), knee subluxation (1), nonunion (1), and one patient developed chronic osteomyelitis secondary to deep pin tract infection. Conclusion: TSF allowed accurate correction of complex limb deformities in children and adolescents with relatively few serious complications. Level of Evidence: Level IV. Case series.

Abstract
BACKGROUND High tibia osteotomy (HTO) is a common surgical operation for correction of genu varum deformity. In some patients, there are concurrent tibia vara and genu varum (bow leg). This study aimed to consider the possibility of better correction of bow leg deformity after double level tibial osteotomy (DLTO). MATERIALS AND METHODS A case series of 10 patients of genu varum in addition to tibia vara (bow leg) deformity who were referred to orthopedic ward of an academic hospital of Isfahan- Iran during 2009-2011 were included in the study. The mean age was 17.3 ± 3.1 years and all of them underwent DLTO. The results of treatment have been assessed based on clinical and radiological parameters before and after surgery. RESULTS The mean pre- and post operative values for Tibia-Femoral Angle, Medial Proximal of Tibia Angle (MPTA), and Lateral Distal of Tibia Angle (LDTA) were 18.13 ± 3.05° vs. 3.93 ± 0.66°, 79.13 ± 3.4° vs. 89.7 ± 1.8° and 96.40 ± 1.8° vs. 88.73 ± 3.0° respectively (P < 0.05). Improvement of all radiological parameters was meaningful. Seventy three percent of patients had normal mechanical axis of limb after surgery. The remaining cases had varus deformity in distal femur that was corrected by valgus supracondylar osteotomy in an additional operation. Limited range of motion (ROM) near knee and ankle was not observed. CONCLUSION DLTO correct bow leg deformity in the point of alignment of limb and paralleling of knee and ankle joint more effectively. This method can be used in metabolic and congenital bow leg which deformities are present in throughout of the lower limb. We described this technique for the first time.

Abstract
OBJECTIVES We describe a way of using Taylor spatial frames (TSFs) for acute deformation of Gustilo IIIB tibial fractures and infected tibial nonunions to close the soft tissue defects and to gradually restore anatomical alignment. We use the Direct Scheduler Utility module of the web-based software for TSFs to successfully restore the anatomical alignment. DESIGN We report a case series of the above technique. SETTING Care was carried out at a tertiary referral center for limb reconstruction. PATIENTS Seven consecutive patients with significant soft tissue loss after tibial fractures were treated. INTERVENTION Defects were closed with acute deformation of the fracture followed by gradual correction to anatomical alignment with a 2-ring TSF. MAIN OUTCOME MEASUREMENT Successful closure of the soft tissue defect was our primary outcome measure. RESULTS Soft tissue defects ranged from 3 to 10 cm. All healed without additional plastic surgery to cover the exposed tibia. Only 1 patient required an additional TSF prescription to achieve anatomical alignment. CONCLUSIONS The use of the Direct Scheduler module of the web-based TSF software allows the complete correction of complex deformities without the need for obtaining complex mounting and frame parameters. We achieved successful closure of soft tissue defects and restored the anatomical tibial alignment in all our cases.

Abstract
PURPOSE A double osteotomy for correcting tibial deformity in combination with medial plateau elevation is recommended for the management of neglected Blount disease cases. We report our clinical experience with the application of this surgical technique and describe the long-term follow-up of the patients who were operated on. METHODS During a 10-year period, eight children (8 boys) with mean age of 12 years (range 9-14 years) underwent surgery (9 operations) due to neglected infantile tibia vara. All patients suffered from stage V or VI Blount disease according to the Langenskiold and Riska classification. Two simultaneous combined osteotomies were performed for medial plateau elevation and for correction of the tibial deformity. The correction was immediate using K-wires for stabilization and a long-leg cast for immobilization. The mean duration of follow-up was 10 years (range 5-15 years), and the evaluations were based on clinical and radiological criteria. RESULTS At the latest follow-up, there was no observable knee flexion or extension restriction and no signs of instability or lateral thrust. All patients had returned to a higher activity level. Leg-lengthening surgery was performed in one child, but the length discrepancy was already present before the double osteotomy was performed. No other complications were noticed. All the angles measured on X-rays had been corrected, and this correction was retained until the latest follow-up. CONCLUSIONS This method results in very good outcomes in patients who suffer from Blount disease of stage V or greater. With this technique, the tibial deformity is corrected, the articular surface is restored, and future recurrence is prevented.

Abstract
Limb deformity can occur in the pediatric and adolescent populations from multiple etiologies: congenital, traumatic, posttraumatic sequelae, oncologic, and infection. Correcting these deformities is important for many reasons. Ilizarov popularized external fixation to accomplish this task. Taylor expanded on this by designing an external fixator in 1994 with 6 telescoping struts that can be sequentially manipulated to achieve multiaxial correction of deformity without the need for hinges or operative frame alterations. This frame can be used to correct deformities in children and has shown good anatomic correction with minimal morbidity. The nature of the construct and length of treatment affects psychosocial factors that the surgeon and family must be aware of prior to treatment. An understanding of applications of the Taylor Spatial Frame gives orthopedic surgeons an extra tool to correct simple and complex deformities in pediatric and adolescent patients.

Abstract
Treatment of neglected fracture dislocations of the ankle poses a surgical challenge. Extensive open reduction can frequently be contraindicated because of local skin conditions and contractures. The Taylor Spatial Frame™ (TSF) has been used to reduce and maintain reduction of complex fractures. Its use in fracture dislocation of the ankle joint has not been described. We describe a case where a TSF was used to reduce and treat a 6-week-old fracture dislocation of the ankle. The TSF is a versatile device, which has a role in the management of both acute and neglected fractures.
