BackgroundEvery year, ~ 210,000 initial implantations of hip endoprostheses are carried out in Germany alone. The "bone cement implantation syndrome" (BCIS) is considered a severe peri- and early-postoperative complication when implanting cemented prostheses. The origin of the BCIS and its impact on the clinical outcome are still uncertain. This study investigates the clinical progression after BCIS cases in patients with cemented hemiarthroplasty. Risk factors for the occurrence of BCIS are evaluated.Material And MethodsClinical data of all patients with a proximal femur fracture and which received a cemented hemiarthroplasty within a period of 9.5 years have been collected. BCIS (+) patients and BCIS (-) patients were compared with respect to their demographics and clinical outcome. Risk factors for the development of BCIS were identified.ResultsA total of 208 patients could be included with complete data sets. The mean age was 81.1 ± 10.0 years. Overall, 37% of the patients showed symptoms of BCIS. In comparison to BCIS (-) patients there was a significantly higher rate of cardiovascular complications (27.3% vs. 13.7%, p = 0.016) and a higher in-hospital mortality rate (15.6% vs. 4.6%, p = 0.006) in BCIS (+) patients. Age, absence of a femoral borehole and ASA status were identified as statistically significant risk factors of BCIS.ConclusionBCIS is frequently observed and in some cases severe complication. The therapy is exclusively symptomatic; identifying preventional measures might reduce the occurrence of BCIS.© 2021. The Author(s).
