Again, without treatment, traditional management would have suggested osteotomy before the age of 4 in this patient population which could have resulted in up to 6 of these patients undergoing proximal tibial osteotomies.
There may dd been other factors that could explain premature failure of screws. Abstract 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.
This minimally invasive method is predictable and well tolerated.
A bonus to all MIMmatch users is the option to sign up for updates on maladiw gene-phenotype relationships. Time to correction averaged Support Radiopaedia and see fewer ads. The second patient underwent only tension-band plate application for tibia vara. Because of the bowing, a leg-length discrepancy may result. Clinically, the child often presents with leg bowing tibia vara with little or no associated pain.

The best means of preventing this scenario is to pre-bend the plate to better fit the contour of the lateral tibial metaphysis and to alternately tighten each screw in an effort to achieve better coaptation of the plate. In patients with full correction, the average length of treatment from initiation to completion was Hemiepiphysiodesis for the correction of angular deformity about the knee. Case with hidden diagnosis.
However, others have successfully corrected tibia vara by performing hemiepiphysiodesis of the proximal tibia employing the Blount staple and more recently, the tension-band plate. Two patients did experience some recurrence of deformity following completion of treatment.
Blount’s disease may come back after surgery, especially in younger children. J Am Acad Orthop Surg ; 3: Two of these patients are asymptomatic with a mild residual deformity and have required no further treatment. Log in Sign up. Full screen case with hidden diagnosis. 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.
Patients were subsequently evaluated in a clinical setting, typically at 3 to 4 month intervals, for tibia vara and tibial torsion.
An exchange of his hardware to the medial side of his tibia resolved the genu valgum D at latest follow-up. Though we feel it is possible children could have a recurrence following 3 to 5 degrees of overcorrection, we have not seen that happen as of yet. Retrieved 7 November Physical examination shows that the lower legs angle outward. It is named after Walter Putnam Blount —an American pediatric orthopedic surgeon.

This study evaluated the efficacy of tension band hemiepiphysiodesis in skeletally immature patients with pathologic tibia vara without regard to patient age or body habitus as long as there was growth remaining.

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.
