Long-term results of total hip arthroplasty with a cemented custom-designed swan-neck femoral component for congenital dislocation or severe dysplasia: a follow-up note.

Background: This follow-up study updates the results in a consecutive series of nineteen cemented total hip replacements with a swan-neck femoral component in patients with congenital dislocation or severe hip dysplasia. The series was previously reported on in 1993.

Methods: The patients were petite, with an average height of 152 cm and an average weight of 50 kg, and the femoral canals could not accommodate an off-the-shelf femoral component.
