Guided growth for tibia vara (Blount's disease).

Medicine (Baltimore) 2016 Oct;95(41):e4951

University of Utah School of Medicine Department of Orthopaedics, Salt Lake City, UT.

Blount's disease is commonly attributed to an intrinsic, idiopathic defect in the posteromedial proximal tibial physis resulting in progressive bowing of the leg, intoeing, and lateral knee thrust. Treatment has historically included bracing, physeal stapling, or corrective osteotomy, and was determined primarily by age at presentation. As we feel the pathology is not necessarily age dependent, we have elected to use the technique of guided growth using a lateral tension band plate to correct limb alignment as a first-line treatment in all patients presenting to our clinic as long as they had growth remaining and no evidence of a physeal bar.

Prevalence of Hypertension in Pediatric Tibia Vara and Slipped Capital Femoral Epiphysis.

J Pediatr Orthop 2016 Dec;36(8):877-883

*Vanderbilt Orthopedic Institute, Monroe Carell Jr. Children's Hospital, Nashville, TN †University of Kentucky and Shriners Hospitals for Children, Lexington, KY.

Background: Slipped capital femoral epiphysis (SCFE) and tibia vara (Blount disease) are associated with childhood obesity. However, the majority of obese children do not develop SCFE or tibia vara. Therefore, it is hypothesized that other obesity-related biological changes to the physis, in addition to increased biomechanical stress, potentiate the occurrence of SCFE and tibia vara. Read More

Evaluation of complications of treatment of severe Blount's disease by circular external fixation using a novel classification scheme.

J Pediatr Orthop B 2015 Mar;24(2):123-30

Texas Scottish Rite Hospital for Children, Dallas, Texas, USA.

Corrective osteotomy for recalcitrant varus deformity secondary to adolescent and infantile Blount's disease can be challenging because of a combination of severity of deformity, complexity of deformity, and frequent association with patient obesity. We present here the outcome of treatment by osteotomy and gradual deformity correction by circular external fixation in 31 patients with either infantile or adolescent Blount's disease. We used a unique classification scheme to quantify and qualify complications in this patient group: category I, complications not requiring an alteration in the treatment plan, not involving unplanned return to surgery, and not influencing outcome; category II, complications requiring an alteration in the treatment plan, including unplanned returns to surgery, but that did not influence outcome; category IIIA, complications that resulted in a failure to achieve treatment goals; and category IIIB, complications that resulted in a failure to achieve treatment goals and the development of a new pathology or worsening of patient condition.

Hemiepiphysiodesis Implants for Late-onset Tibia Vara: A Comparison of Cost, Surgical Success, and Implant Failure.

J Pediatr Orthop 2016 Jan;36(1):29-35

*Vanderbilt Orthopaedic Institute Medical Center East †Monroe Carell Jr. Children's Hospital, Nashville, TN.

Background: The purpose of this study was to compare hemiepiphysiodesis implants for late-onset tibia vara and to evaluate patient characteristics that may predict surgical failure.

Methods: This is a retrospective review of late-onset tibia vara patients treated with temporary hemiepiphysiodesis from 1998 to 2012. Mechanical axis deviation (MAD), mechanical axis angle, mechanical lateral distal femoral angle, and medial proximal tibial angle were measured on standing bone length radiographs. Read More

Magnetic resonance imaging of the pediatric knee.

Magn Reson Imaging Clin N Am 2014 Nov 1;22(4):743-63. Epub 2014 Nov 1.

Musculoskeletal Radiology, University of Wisconsin School of Medicine and Public Health, E3/366, 600 Highland Avenue, Madison, WI 53792-3252, USA.

In pediatric patients, the high resolution and excellent soft-tissue contrast of magnetic resonance (MR) imaging allows for complete evaluation of osseous and soft-tissue structures around the knee joint, and its lack of ionizing radiation makes it a preferred modality for advanced imaging. Older children and adolescents are most commonly imaged to evaluate athletic and traumatic injuries, whereas in infants and school age children MR imaging is used to evaluate developmental conditions such as Blount disease or assess for causes of atraumatic pain such as infection or inflammatory arthritis. A thorough understanding of normal skeletal development is necessary to avoid misdiagnoses. Read More

Blount disease: an update.

Orthop Clin North Am 2015 Jan 12;46(1):37-47. Epub 2014 Oct 12.

Division of Pediatric Orthopedics, Department of Orthopedics, Rutgers New Jersey Medical School, 90 Bergen Street, DOC 7300, Newark, NJ 07103, USA. Electronic address:

Blount disease is a developmental disorder associated with childhood obesity. Based on whether the deformity is first noted before or after 4 years of age, early-onset and late-onset forms of Blount disease have been described. Besides physeal abnormalities of the proximal tibia, compensatory changes in the intra-articular morphology of the medial compartment of the affected knee are often noted on MRI scan. Read More

Treatment of Adolescent Blount Disease Using Taylor Spatial Frame With and Without Fibular Osteotomy: Is There any Difference?

J Pediatr Orthop 2015 Jul-Aug;35(5):501-6

Pediatric Orthopedic Unit, Ruth Children's Hospital, Rambam Health Care Campus; Rappaport Faculty of Medicine, Technion-Israel Institute of Technology, Haifa, Israel.

Background: In adolescents, Tibia Vara (Blount disease) patients usually present with combination of marked genu varum, procurvatum, and internal tibial torsion. When no growth remaining, standard treatment protocol for correction is osteotomy of the proximal tibia and fibula. In our study we compared 2 groups of patients: group A was treated with fibular osteotomy and group B was treated without fibular osteotomy. Read More

Tibia vara and slipped upper femoral epiphysis: is there an association?

J Pediatr Orthop B 2015 Jan;24(1):46-9

Department of Orthopaedics & Traumatology, Hospital Universiti Kebangsaan Malaysia, Kuala Lumpur, Malaysia.

Tibia vara and slipped upper femoral epiphysis (SUFE) share a common risk factor, but their relationship is unclear. In both conditions, the patients are usually obese. To the best of our knowledge, there have been only two previous reports in the literature that have described the occurrence of tibia vara and SUFE in three patients. Read More

Late onset tibia vara. Acute correction strategy: proper case selection and a simple external fixation technique.

Acta Orthop Belg 2014 Jun;80(2):241-50

Following proximal tibial osteotomy for cases of late onset tibia vara, both acute and gradual correction strategies were described, where each has its pros and cons. The aim of this study was to verify the proper selection criteria of cases with late onset tibia vara amenable to successful acute correction strategy using a homogenous patient group with clear inclusion criteria; all the cases were fixed by a low profile semicircular fixator module. Thirty legs in 20 patients (11 boys, nine girls) with late onset tibia vara, treated in our department between January 2005 and February 2008, that complied well with the assigned inclusion criteria constituted the material of this prospective study.

Do we need to do overcorrection in Blount's disease?

Int Orthop 2014 Aug 13;38(8):1661-4. Epub 2014 May 13.

Department of Orthopedics Surgery, Faculty of Medicine, Siriraj Hospital, Mahidol University, Bangkok, Thailand,

Purpose: In order to prevent recurrent deformity, overcorrection in Blount's disease has been a common practice by most paediatric orthopaedic surgeons. However, some patients have persistent valgus alignment resulting in awkward deformity. The femoro-tibial angle (FTA) was measured in this series of cases to determine the necessity of such practice.

External fixation for closed pediatric femoral shaft fractures: where are we now?

Clin Orthop Relat Res 2014 Dec;472(12):3814-22

Department of Orthopaedic Surgery, Rutgers University-New Jersey Medical School, Doctor's Office Center, 90 Bergen Street Suite 7300, Newark, NJ, 07103, USA,

Background: Recent advances in external fixation technique and pin design have sought to minimize complications such as pin site infection and premature removal of the external fixator. Although newer forms of internal fixation have gained popularity, external fixation may still have a role in managing pediatric femoral shaft fractures.

Questions/purposes: We sought to assess the time to healing, limb alignment, and complications observed in a cohort of pediatric patients with closed femoral shaft fractures who were treated with external fixation. Read More

Stress distribution comparisons of foot bones in patient with tibia vara: a finite element study.

Acta Bioeng Biomech 2013 ;15(4):67-72

Department of Mechanical Education, Technical Education Faculty Kocaeli University, Umuttepe Campus, Kocaeli, Turkey.

Blount's disease, or tibia vara, is the most common cause of pathologic genu varum in children and adolescents. Changes in the loading of knee structures such as tibial articular cartilage, menisci and subcondral bone are well documented in case of genu varum. But the mechanical effects of this condition on foot bones are still questionable. Read More

Is there a difference in sagittal alignment of Blount's disease between radiographic and clinical evaluation?

Clin Orthop Relat Res 2014 Dec;472(12):3807-13

Department of Orthopedic Surgery, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul, Korea,

Background: A procurvatum deformity of the proximal tibia often is seen in patients with Blount's disease. If left untreated, it can lead to progressive angulation in the sagittal plane and altered contact stresses across the knee.

Questions/purposes: We asked the following questions: (1) Is the mean angle of procurvatum measured from full-length lateral radiographs of the tibia greater than that of procurvatum measured from clinical photographs of the affected lower extremity? (2) Is there a linear relationship between radiographically measured procurvatum and radiographically measured procurvatum?

Methods: We treated 72 patients surgically for Blount's disease between 1997 and 2012; of those, 29 patients were excluded from this analysis because they did not have adequate photographs or radiographs, leaving 43 patients (60% of the patients treated surgically; 47 limbs total), mean age of 13 years (range, 6-25 years), who underwent surgical realignment for Blount's disease were retrospectively evaluated at a median of 97 months after surgery (range, 24-170 months).
