Information on the use of absorbable rods in salter's osteotomy, a surgical procedure for treating acetabular dysplasia. The advantages and disadvantages of using self-reinforced polyglycolic acid (sr-pga) and self-reinforced poly-levo lactic acid (sr-plla) rods, including their initial bending strength, loss of strength, and complete resorption rates. The document also mentions the problems associated with k-wires and the potential benefits of replacing them with absorbable rods. Studies on the use of absorbable rods in pediatric fractures are also cited.
