Arthrodesis

Another limb sparing procedure is the iliofemoral or ischiofemoral arthrodesis. Although, these procedures lead to significant leg length discrepancy, patients are sometimes able to have near normal gait.¹⁰

Long term complications of these arthrodeses include non-union and pseudoarthrosis (up to 50% of the time).  As well, premature degenerative changes are seen in the lumbar spine because of the patients new walking dynamics.⁸
