Abstract Background Tibia vara (Blount’s disease) is an orthopedic condition that affects young children causing varus deformity of the knee. Blount described tibia vara as “an osteochondrosis located at the medial side of the proximal tibial epiphysis.” Currently, tibia vara is considered an acquired disease of the proximal tibial metaphysis, However, rather than an epiphyseal dysplasia or osteochondrosis. The exact cause is unknown, but enchondral ossification seems to be altered. Suggested causative factors include infection, trauma, osteonecrosis and a latent form of rickets, although none of these has been proved. Combination of hereditary and developmental factors is the most likely cause. Weight bearing must be necessary for its development because it does not occur in non-ambulatory patients and the relationship of early walking and obesity to Blount disease has been clearly documented. Purpose to establish, through the literatures, what is the effectiveness of temporary hemiepiphysiodesis by eight plate in treating Blount’s disease. Methodology A systematic review was carried out on several studies which met the inclusion criteria. In this Study we conducted an up-to-date review of the studies discussing results of use of eight plates in temporary hemiepiphysiodesis in Blount disease and published between June 2008 and June 2018. Results in our study, success rate is 67.1% with a considerable rate of correction of mechanical axis deviation ranging between 0.58 mm\month to 1.5mm\month. Success rate in infantile age group was 95%, while in adolescent age group was 48%. Conclusion it is evident that results of 8-plate in Blount disease is much better in infantile group of age than adolescent group. So, 8-plate can be used in treatment of Blount’s disease up to stage IV. The results are better in low BMI and younger age group .

Rare Case Report

<p class="abstract">Blount’s disease is more common in Afro-Caribbean, obese, female child. Early walking have been associated with the disease process. Adult patients with Blount’s disease who received no treatment previously, are rarely reported across the other parts of the world and hence less discussed. The treatment of neglected cases of Blount’s disease often requires correction of varus deformity, internal tibial torsion and medial plateau depression. We are reporting one such patient seen at our hospital. A skeletally mature, obese (BMI 43.2), male patient with bilateral tibia vara was operated for hemi-plateau elevation combined with a valgus osteotomy. Fixation was achieved with plate and staples. Surgical correction of one such patient is technically demanding and more complicated. If left untreated , the main risk is premature osteoarthritis.</p>

Abstract Background Despite multiple published reviews, the optimum method of correction and stabilisation of Blount’s disease remains controversial. The purpose of this study is to evaluate the clinical and radiological outcomes of acute correction of late-onset tibial vara by percutaneous proximal tibial osteotomy with circular external fixation using two simple rings. Weighing up the pros and cons and to establish if this method would be the method of choice in similar severe cases especially in a context of limited resources. Methods This study was conducted between November 2016 and July 2020. We retrospectively reviewed the clinical notes and radiographs of 30 patients (32 tibiae) who had correction of severe late-onset tibia vara by proximal tibial osteotomy and Ilizarov external fixator. The mean age at the time of the operation was 16.6 (± 2.7) years (range 13–22). Results The mean proximal tibial angle was 65.7° (± 7.8) preoperatively and 89.8° (± 1.7) postoperatively (p < 0.001). The mean mechanical axis deviation improved from 56.2 (± 8.3) preoperatively to 2.8 (± 1.6) mm postoperatively (p < 0.001). The mean femoral-tibial shaft angle was changed from –34.3° (± 6.7) preoperatively to 5.7° (± 2.8) after correction, with degree of correction ranging from 25° to 45°. Complications included overcorrection (three cases 9%) and pin tract infection (eight cases 25%). The mean Hospital for Special Surgery knee scoring system (HSS) improved from 51.03 (± 11.24) preoperatively to 94.2 (± 6.8) postoperatively (p < 0.001). The mean length of follow up period 33.22 (± 6.77) months, (rang: 25–46 months). At final follow up, all patients had full knee range of motion and normal function. All cases progressed to union and there were no cases of recurrence of deformity. Conclusion This simple procedure provides secure fixation allowing early weight bearing and early return to function. It can be used in the context of health care systems with limited resources. It has a relatively low complication rate. Our results suggest that acute correction and simple circular frame fixation is an excellent treatment choice for cases of late-onset tibia vara, especially in severe deformities.

Blount’S Disease

Blount’s disease, also known as tibia vara, is a developmental disorder involving the posteromedial proximal tibial physis resulting in progressive varus, procurvatum and internal torsion of the affected tibia 1. The condition was first published by Blount in 1973 2. The aetiology of this disease is unkown. However, associations exist between blount’s disease and the Afro-Caribbean race, early age of walking and obesity 3, 4. Furthermore, genetic predisposition has been postulated as well as mechanical loading of the physis 4, 5, 6. Affected children are usually overweight and start walking early. It is bilateral in 80% of cases 7.

ABSTRACT Infantile Blount's disease results in multi-planar proximal tibial deformity consisting of varus, procurvatum, internal rotation and shortening. The deformity is attributed to disordered growth of the posteromedial proximal tibial physis. The aetiology is multifactorial. It is associated with childhood obesity and African ethnicity. The ability to differentiate between infantile Blount's disease and physiological bowing depends on the findings of focused clinical examination, X-ray appearance, tibial metaphyseal-diaphyseal angle and tibial epiphyseal-metaphyseal angle. The gold standard of treatment is proximal tibial metaphyseal corrective osteotomy before the age of 4 years. The limb should be realigned to physiological valgus. The recurrence rate after realignment osteotomy is high. Recurrence is associated with age at osteotomy, obesity, higher Langenskiöld stage and medial physeal slope >60°. The surgical management of severe, recurrent or neglected infantile Blount's disease is challenging. Comprehensive clinical examination and multi-planar deformity analysis with standing long leg X-rays are essential to identify all aspects of the deformity. Distal femur coronal malalignment and significant rotational deformity should be excluded. Knee instability due to intra-articular deformity should be corrected by elevation of the medial tibial plateau. Lateral epiphysiodesis should be done at the same time as medial plateau elevation and when medial growth arrest is certain to prevent recurrence.
