- unlike anterolateral bowing, this disorder is not assoc w/ other anomalies (like neurofibromatosis) nor is it associated w/ tibial
frxs or pseudarthrosis, such as congenital pseudarthrosis of tibia;
- clinical findings:
- posteromedial bowing
- calcaneal valgus
- limb-length inequality;
- triceps surae weakness;
- Limb Shortening: (see: limb growth deformities)
- limb is shortened 1 -1.5 cm at birth;
- some will have limb length discrepancies avg 4.0 cm at maturity;
- growth inhibition usually remains as a constant percentage over time, thus allowing future equalization procedures can be
- treatment options:
- contralateral epiphysiodesis;
- ipsilateral limb lengthening;
- angular deformity corrects spontaneously, but medial bowing may persist.
- occasionally, osteotomy is necessary to correct medial bowing.
- no orthotics are necessary and the patient should be observed.
- Calcaneal Valgus:
- calcaneal valgus foot position resolves gradually
Posteromedial bowing of the tibia. Progression and discrepancy in leg lengths.
