Abstract
Objectives: To identify acetabular fracture patterns classified according to Letournel that are at risk of conversion to total hip arthroplasty (THA).
Design: A retrospective cohort study.
Setting: A Level-I trauma center.
Patients/ participants: Patients with an acetabular fracture, classified according to Letournel who were treated with ORIF (n = 280).
Interventions: Various surgical treatments for acetabular fractures.
Main outcome measure: The primary outcome was the rate of conversion to total hip arthroplasty.
Results: In this study, an overall conversion rate to THA of 13.9% within 2.2 years after initial surgery was found. Multivariate analysis revealed that several factors, namely, T-shaped fracture patterns (OR: 7.5, 95% CI 1.9-28.8, p = 0.003) and residual displacement (> 2 mm) (OR: 3.7, 95% CI 1.6-8.5, p = 0.002) are associated with an increased risk of conversion to THA. Furthermore, the risk of conversion to THA increases with 4.7% per gained year of age (OR: 1.047, 95% CI 1.0-1.1, p = 0,001). Other fracture patterns classified according to Letournel were not found to be independent risk factors.
Conclusion: The presence of T-shaped fracture patterns is found to be an independent risk factor for conversion to THA. Furthermore, age and degree of reduction are found to be independent risk factors, which is in line with existing literature. These finding should be taken into account when treating patients with T-shaped acetabular fractures.
Level of evidence: Prognostic study level III. See Instructions for Authors for a complete description of levels of evidence.
期刊介绍:
The European Journal of Trauma and Emergency Surgery aims to open an interdisciplinary forum that allows for the scientific exchange between basic and clinical science related to pathophysiology, diagnostics and treatment of traumatized patients. The journal covers all aspects of clinical management, operative treatment and related research of traumatic injuries.
Clinical and experimental papers on issues relevant for the improvement of trauma care are published. Reviews, original articles, short communications and letters allow the appropriate presentation of major and minor topics.
