Percutaneous column screw fixation with hip arthroplasty produced stable acetabular cups in most geriatric fractures.

Background

Periprosthetic acetabular fractures and acetabular fractures are becoming increasingly common in the elderly population.

Purpose

The aim of this study is to retrospectively evaluate the clinical and radiological outcomes thereafter.

Methods

This is a single-centre, prospective cohort study.

n = 51 patients

Results

cup stayed stable on follow-up imaging in nearly all hips

95%

Stable cup

5%

Loosening

More results

Median intraoperative blood loss was 600 mL (0-2'700).

Median operating time was 255 min (range 169-430).

Thirty-day mortality was 10% and revision rate 12%.

Thirty-six patients (69%) returned to their previous social environment and thirty-four patients (65%) regained pre-traumatic walking abilities.

Conclusion · 1 of 3

Navigated percutaneous screw fixation of the anterior and posterior columns combined with total hip arthroplasty may lower the impact of surgery in a rather frail cohort of geriatric patients.

Conclusion · 2 of 3

The buttressing effect of the column screws may enhance overall stability of the cup even without fracture reduction, thus providing a stable construct to allow immediate unrestricted weight bearing.

Conclusion · 3 of 3

Preinjury levels of independency and walking abilities could be fully restored in the majority of our cohort.
