Contralateral hip joint degeneration associated with a cam-type deformity of the proximal femur in a retired chiropractor: 10-year follow-up.

Cam-type deformities of the proximal femur have long been associated with femoroacetabular impingement (FAI); an orthopedic condition recognized in the etiology of early osteoarthritis (OA) in the non-dysplastic adult hip. However, the optimal clinical management (including the long-term prognosis) of patients with cam-type deformities with or without FAI symptoms remains uncertain. In this imaging case review (ICR), we present the 10-year follow-up of a retired chiropractor with bilateral cam-type femoral deformities who initially underwent total right hip joint arthroplasty for advanced hip joint OA, and subsequently developed advanced hip joint OA on the contralateral side.
