Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A retrospective consecutive population of patients treated with conical tapered stems in cementless total hip arthroplasty for osteoarthritis due to congenital hip pathologies will be selected. The aim of this retrospective study is to evaluate the long-term clinical and radiographic results of this implant and the survival rates in such a specific cohort.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Congenital hip pathologies may severely alter the local anatomy of the hip, making total hip arthroplasty (THA) due to osteoarthritis after congenital hip pathologies challenging. While it seems that congenital hip pathologies did not significantly influence the outcomes when compared to THA after osteoarthritis, the choice of implant was demonstrated to impact the survival rates of the THA after congenital hip pathologies.

To date, no guidelines exist about the correct choice of hip implant in congenital hip pathologies: only mid-term case series are available. Conical tapered stems have been frequently suggested for the most difficult cases.

The aim of this study is to describe the survival rates and the long-term clinical and radiological outcome of conical tapered stems in THAs after congenital hip pathologies.
