Fragility Fractures of the Pelvis: New Approaches to Classification and Management

Abstract

Purpose of Review

The purpose of the present article is to review the new approaches to classification and management of fragility fractures of pelvis.

Recent Findings

Fragility fractures of the pelvis (FFPs) account for approximately 7% of fragility fractures and are increasing in incidence due to the aging population, an increase in life expectancy, and a more active life-style. The FFPs are characterized by isolated bone disruption and are generally more stable than high-energy pelvic ring fractures due to intact ligaments. Due to differences in the degrees of instability, the traditional classification systems (Tile or Young and Burgess) for acute pelvic ring injuries from high-energy trauma may not be applicable to FFPs. Through a classification system based on fracture location and the degree of instability, FFPs can be appropriately managed with either conservative treatment or surgery.

Summary

Fragility fractures occur in patients with primary or secondary osteoporosis from low-energy trauma or no known trauma. FFPs are different from high-energy pelvic fractures in the degree of instability and the approach to fracture management. Diagnosis of FFPs requires a high index of suspicion and the early use of CT or MRI to prevent long-term complications.
