Indications for surgical fixation of low-energy pelvic ring fractures in elderly: a systematic review

Abstract

Introduction There are no generally accepted criteria for when and how to fixate osteoporotic pelvic ring fractures in elderly. This systemic review aims to summarize the currently available literature regarding the indications and methods for surgical fixation of fragility fractures of the pelvic ring in elderly patients after low-energy trauma. Materials and methods The Pubmed and Embase databases were searched using the key words pelvic fractures, geriatric, fragility, osteoporosis, and surgical fixation, and their synonyms. Extracted data including the indication, method of operative fixation, and post-operative outcomes (pain levels, mobility, complications and mortality) were analyzed using descriptive statistics. The studies were too heterogeneous to perform a meta-analysis. Results Eleven cohort studies (3 comparative and 8 noncomparative) were included. The methodological quality was poor to moderate; the studies were heterogeneous regarding study design and reported outcomes. In all included studies operative treatment for all fracture types was preceded by a period of conservative treatment comprising physiotherapy-guided full weight-bearing. Time to surgery differed widely. For posterior ring fixation, the majority of the included studies used minimally invasive surgery with trans-iliosacral screws. Five studies described a form of additional fixation of the anterior pelvic ring but did not report the indications. Conclusions Fixation of low-energy pelvic ring fractures in elderly is commonly performed after a period of conservative treatment, with persistent pain as the most frequent indication for fixation. Fracture classification based on stability seems to be of secondary importance. Timing for surgical fixation of the pelvic ring fracture in elderly patients remains diverse. Large well-designed comparative prospective studies and randomized controlled trials are needed to provide clearly substantiated guidelines.

Pelvic Ring Fractures in Older Adult Patients—Assessing Physician Practice Variation among (Orthopedic) Trauma Surgeons

“…The main goal of treatment for pelvic fractures, whether conservative or surgical, is to sustain mobility and consequently prevent the negative effects of prolonged immobility [24,25]. According to the most recent studies, fracture type, mobility level, and pain should all influence the decision to proceed with surgical treatment [26][27][28][29][30][31]. This survey shows that after 2 weeks of reduced mobility and pain, surgical stabilization is not recommended by many treating physicians, especially in frail patients.…”
