简要总结
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.
详细描述
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.

结局指标
主要结局
Radiographic Stem Osseointegration
时间窗: 15 months
Osseointegrated stems described according to Engh's criteria
Harris Hip Score
时间窗: 15 months
Mean clinical results at last follow-up evaluated using the Harris hip score. Minimum-maximum values: 0-100. Best result: 100.
Radiographic Cup Osseointegration
时间窗: 15 months
Osseointegrated cups described using the Moore's criteria: the cup is osseointegrated when at least 3 criteria are present (radial trabeculae, superolateral buttress, inferolateral buttress, medial stress shielding, absence of radiolucent lines).
Survival Rate
时间窗: 15 months
Percentage of survived implants (no component exchange or removed) described using Kaplan-Meier curve with 95% confidence interval. Minimum-maximum values: 0-100. Best result: 100.
