For Perthes Disease, Are Two Osteotomies Better than One?

LCP_Osteotomies.pngIt is well accepted that kids with Legg-Calve-Perthes (LCP) disease do best when their condition is diagnosed and managed before 6 years of age. Surgical treatment is often recommended for children 6 years and older who have more severe femoral-head involvement, and orthopaedists perform combined pelvic and femoral varus osteotomies on some of those children.

In the February 1, 2107 edition of The Journal, Mosow et al. compare 10-year outcomes in 52 LCP patients who underwent combined osteotomies (mean age at surgery of 7.9 years) with results reported in the literature for single pelvic or femoral osteotomies. Although the postoperative radiographic and functional results after combined osteotomy were good, they were overall no better than those reported in the literature for either osteotomy alone.

The authors admit that in the absence of a randomized study design, these findings should be interpreted with caution, but they conclude that “it is not recommended that combined osteotomies for this age group routinely be used.”
