Does bone morphogenetic protein-2 enhance bone formation when delivered by a synthetic matrix containing hydroxyapatite/tricalciumphosphate?
It is concluded that rhBMP-2 significantly enhances bone regeneration in rabbits when delivered by a synthetic matrix containing HA/TCP. This synthetic PEG matrix containing HA/TCP granules apparently fulfills a number of criteria required for an ideal carrier system for rhBMP-2.
Our review demonstrates that newborns with a rectoperineal fistula frequently have associated anomalies and should undergo an evaluation similar to more complex lesions. These findings illustrate the importance of a structured approach to the evaluation of even the most straightforward lesions.
