Abstract

Introduction

End-stage renal disease (ESRD) leads to multiple systemic effects and patients suffer from multiple comorbidities including fractures. While previous studies have examined complications following hip fracture surgery in ESRD patients, there are no studies evaluating other lower extremity fractures. This study aimed to identify postoperative complication risk in patients with ESRD who had lower extremity fractures.

Methods

Using our database from 2000 to 2015 at two level-one trauma centres, we collected data on patients over age 40, who had lower extremity fractures and surgical fixation. Diagnosis of ESRD was made before the injury. Each ESRD patient was matched by two non-ESRD patients regarding age, gender, American Society of Anaesthesiologists (ASA) score, and AO/OTA fracture classification. Postoperative outcomes were non-union, mechanical failure, and infection. The number of outcome events was compared between the ESRD and non-ESRD cohorts.

Results

A total of 195 patients (65 ESRD patients matched to 130 non-ESRD patients) were identified. Median follow-up was 31 months (12–141 months). Patients with ESRD were 3.6 time more likely to have at least one postoperative complication (mechanical failure, non-union, or infection) compared to non-ESRD patients (9/65 vs. 5/130, p = 0.02). In particular, mechanical failure was eight times higher among ESRD patients compared to non-ESRD patients (8/65 vs. 2/130, p < 0.01).

Conclusions

ESRD was associated with higher rates of complications, especially mechanical failure, after lower extremity fracture surgeries.
