Blount’s disease

Presentation Leg bowing but otherwise asymptomatic, in particular no history of pain. Full screen case with hidden diagnosis.

This condition is more common among children of African ancestry. J Pediatr Orthop B ; bkount Clin Orthop Rel Research ; Ferriter P, Shapiro F. We identified 17 patients with tibia vara 27 bloubt who were managed by means of guided growth of the proximal tibia, from age 1. There may have been other factors that could explain premature failure of screws. The mechanical axis was evaluated by drawing a line from the center of the femoral head to the blohnt, bisecting the knee. The other now age 11 years underwent reimplantation of the tension-band plate and has subsequently corrected his mechanical alignment.

Mmaladie for errors and try again. J Pediatr Orthop ; 2: B AP standing full length showing resolution of the genu varum after guided growth using an 8 plate. One patient was lost to follow-up shortly after treatment. Proximal tibial osteotomy and Taylor Spatial Frame application for correction of tibia vara in morbidly obese adolescents.

The adjacent metaphysis is also depressed and has a beak-like protuberance of rarified bone oriented medially.

Case 10 Case For leg bowing consider: Seventeen patients 27 limbs were identified with a diagnosis of pathologic tibia vara and who were treated between and with temporary hemiepiphysiodesis using tension-band plating. Sevastikoglou and Eriksson observed 4 affected with the infantile form in a sibship of 6 children. All patients were followed in an outpatient setting by a single surgeon.


While the OMIM database is open to the public, ma,adie seeking information about a personal medical or genetic condition are urged to consult with a qualified physician for diagnosis and for answers to personal questions.

Blount described 22 cases of bowlegs in infants, with progressive deformity and radiologic findings of sloping proximal tibial malacie and a medial beak of the metaphysis. 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. J Pediatr Orthop ; 5: It is also associated with obesityshort stature, and early walking.

We did see recurrence in 2 patients. The tibiae demonstrate varus positioning with abnormal triangular epiphyses. Essentials of skeletal malarie. It should be noted maladir we generally overcorrect to 3 to 5 degrees of genu valgus to allow for some physeal rebound following plate removal.

There were no peri-operative complications.

Relative tibial and femoral varus as a predictor of progression of varus deformities of the lower limbs in young dd. Retrieved 7 November In other projects Wikimedia Commons. Two patients have undergone corrective osteotomies with good results. The lateral cortical wall of the upper tibial metaphysis remains notably straight. C AP standing full length after removal of hardware. This patient eventually went on to have a multi-planar osteotomy with application of a spatial frame on the right side but had enough correction of the varus deformity on the left to require an isolated distal tibial rotational osteotomy to correct the excessive torsion.


A biomechanical analysis of the etiology of tibia vara.

Nilsonne, who published early case reports of the condition. The authors have no funding and conflicts of interest to disclose.

However, there has been no direct correlation drawn between BMI and hardware failure, nor a consistent pattern in relating failure with adolescent Blount’s disease.

Multiplanar deformity analysis of untreated blount disease. C ] – Bowleg with progressive deformity. Two patients had breakage of 1 or more of their screws including failure of a single metaphyseal screw in 1 patient and breakage of both the metaphyseal and epiphyseal screws in the other. One of these patients received suggestion for an osteotomy to address a persistent moderate unilateral deformity but opted against further treatment.

Each of these patients presented maladiee the age of 6 years. The reason for the migration is still unclear, but as with the screw failures, it was discovered at completion of treatment and simply removed with no evidence of further growth abnormality.

Guided growth for tibia vara (Blount’s disease)

Case Discussion Findings are consistent with Blount disease also known as tibia vara which refers to a local disturbance of growth of the medial proximal tibial epiphyses.

Methods This was an IRB approved, single institution, retrospective cohort study.

None of the 17 patients experienced any immediate perioperative complications. Log in Sign up. Case 1 Case 1.
