Hypophosphatemic Rickets: The Role of HemiepiphysiodesisNovais, Eduardo MD*; Stevens, Peter M. MD†Journal of Pediatric Orthopaedics: March/April 2006 - Volume 26 - Issue 2 - pp 238-244 doi: 10.1097/01.bpo.0000218531.66856.b7 Knee/Tibia: Original Article Abstract Author Information Abstract: Despite early medical intervention, children with hypophosphatemic rickets often have progressive deformities in the lower extremities. With the forces imparted by gravity and weight bearing, varus or valgus deformities that might otherwise have been physiological are likely to progress, causing gait disturbance and pain. Proper medical management is important and may theoretically slow or prevent the progression of varus or valgus, but is ineffective at correcting deformity once established. We have reviewed the literature and gathered a series of 10 patients, most of whom underwent hemiepiphysiodesis. We are presenting the rationale for, and the results of, that surgery, in an effort to define the role of this minimally invasive procedure.
