Avascular Necrosis in Congenital Dislocation of the Hip: Long-Term Results and Proposed new Classification
Keyword(s):
A new classification is proposed for post-reduction necrosis of the femoral epiphysis based on retrospective analysis of 54 cases with a mean follow-up of 15 years. Necrosis can be divided under two main headings: A) partial, involving only the epiphysis B) total, involving the metaphyseal cartilage. Four total forms have been identified: B1: eventually resulting in coxa valga B2: eventually resulting in a short stubby neck, oval head and coxa magna B3: eventually resulting in coxa vara and severe acetabular dysplasia B4: eventually resulting in hypoplasia of the whole hip joint. This classification system comprises all the aspects of necrosis, while at the same time providing guidelines for treatment and long-term planning.
