Challenges and outcome of total hip arthroplasty in patients with developmental dysplasia of the hip: a clinical series with a spectrum of disease manifestation and technical notes

Patients with developmental dysplasia of hip eventually lead on to secondary osteoarthritis in adulthood and may end up with total hip arthroplasty at a younger age. Because of the altered anatomy of dysplastic hips, total hip arthroplasty in these patients is a technically demanding procedure. Altered anatomy of the acetabulum and proximal femur together with leg length discrepancy pose challenges during total hip arthroplasty. Since the majority of the patients are in the younger age group, soft tissue balance is of great importance to maximise postoperative functional result and longevity of prosthesis. In this paper, we present a series of our patients with a spectrum of disease manifestation from mild to severe form and also discuss the associated challenges and the technical solutions and their outcome.
