Key result
Severe murine hip destabilization causes complete dislocation while moderate instability induces lateralization without dislocation.

This murine model of hip instability may elucidate dysplasia-OA mechanisms; leaves open clinical translation pending validation in larger species.
Does surgically-induced unilateral hip instability lead to morphometric changes in the maturing mouse hip?
A novel murine model of titrated surgical hip destabilization successfully induces morphometric changes mimicking acetabular dysplasia and impingement during postnatal maturation.
Killian et al. (2018) studied Acetabular dysplasia and hip deformity (n=36). Surgical destabilization of the hip vs. Contralateral sham-operated hip was evaluated on Acetabular coverage and joint morphology. Severe surgical destabilization of the postnatal murine hip led to complete dislocation and formation of pseudoacetabula, whereas moderate instability induced lateralization of the femoral head without dislocation.
