Fixation of subcapital femoral osteotomies by poly-L-lactic acid pins : an experimental study in sheep

In an experimental study in nine sheep, self-reinforced poly-L-lactic pins were used to fix subcapital femoral osteotomies. One out of three was consolidated at 3 weeks. At 6 weeks, one out of 3 had failed, and the other two were united by bone. At 12 weeks all the osteotomies had healed. These resu...

Zusammenfassung:	In an experimental study in nine sheep, self-reinforced poly-L-lactic pins were used to fix subcapital femoral osteotomies. One out of three was consolidated at 3 weeks. At 6 weeks, one out of 3 had failed, and the other two were united by bone. At 12 weeks all the osteotomies had healed. These results showed that absorbable SR-PLLA pins could be used to fix this type of osteotomy.
