Introduction Although many articles report complications after pelvic ring and acetabular fracture surgery, a general overview of complication rates and potential risk factors is lacking. The current review provides a comprehensive summary of the complications after pelvic ring and acetabular fracture surgery in relation to the surgical approach. Material and Methods Pubmed and Embase databases were systematically searched using the key words: pelvic fracture, acetabular fracture, fixation, surgical approaches, complications, and their synonyms. Extracted data included patient and fracture characteristics, surgical approaches, and post-operative complications; surgical site infections (SSI), implant-related complications, malunion and non-union. Study data were summarized using descriptive statistics. Results Twenty-two studies (twenty-one retrospective cohort studies, of which three comparative, and one randomized controlled trial) were included in this review. The overall complication rates reported for the included surgical approaches were: 17% for the (Modified) Stoppa approach, 11% for percutaneous fixation, 5% for the Kocher–Langenbeck approach, 7% for the ilioinguinal approach and 31% for external fixation. The most frequent complications were SSI (22%) and neurological (31%) complications, which were most often reported in patients treated with an external fixator. Re-operation rates were comparable for the surgical approaches (4–8%). Two studies reported on risk factors and identified concomitant traumatic injuries, prolonged ICU stay and high body mass index as risk factors for SSI. Conclusion External fixation of pelvic fractures is associated with highest complications rates including SSI’s and neurological complications. Although post-operative complications are frequently reported after pelvic fracture surgery, more studies are needed that identify potential risk factors. These will assist the surgeon in (pre)operative decision making and development of preventive strategies.

Purpose Post-operative complications following fixation of pelvic fractures can lead to mortality and increased morbidity. Available literature regarding complications is heterogeneous and knowledge on risk factors is limited. This study aims to identify the most common post-operative complications and their possible risk factors following pelvic fracture surgery. Methods A retrospective cohort study was performed in two level-1 trauma centers in the Netherlands between January 2015 and January 2021. Included patients were all adult patients (≥ 18 years) with an operatively treated pelvic fracture (pelvic ring and/or acetabular fractures). Post-operative complications included surgical site infections (SSI), material-related complications, neurological complications, malunion/non-union and performed reoperations. A forward stepwise multivariable logistic regression analysis was used to identify any risk factors associated with these complications. Results Complications occurred in 55 (24%) of the 233 included patients. SSI’s were most common, occurring in 34 (15%) patients. Duration of surgery (odds ratio 1.01 per minute, 95% confidence interval 1.00–1.01) and obesity (odds ratio 1.10 per BMI point, 95% confidence interval 1.29–7.52) were independent risk factors for development of SSI. Less common post-operative complications were material-related complications (8%) and neurological damage (5%). Conclusion Limiting operation time by using less invasive and less time-consuming surgical approaches may reduce the risk of SSI. More awareness and post-operative screening for early signs of SSI is mandatory, especially in obese patients. Future research should include large prospective patient cohorts to determine risk factors for other post-operative complications associated with pelvic fracture surgery.

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.
