Sacral fragility fractures: risk factors and outcomes after cement sacroplasty
Abstract
BACKGROUND: The objective of the present study on patients with fragility fractures of the sacrum (FFS) was to assess existing risk factors and clinical outcomes after cement sacroplasty (CSP).
PATIENTS AND METHODS: 68 patients (64 women, 4 men) with previous FFS were followed up retrospectively. CT and MRI images were used to classify fractures according to Denis et al. and Rommens and Hofmann. Bone mineral content was determined by QCT in all patients. Concomitant diseases as well as central and peripheral fractures were recorded, considering the patient's medical history and X‑ray images. Vitamin D levels were also determined. If conservative therapy was unsuccessful, CSP was performed. The results were documented on the basis of pain development, physical independence, patient satisfaction, complication rate and mortality.
RESULTS: The age of the women in the study was Ø 83.2 (72-99) and that of the men Ø 77.8 (76-85) years. 42.4% had a Denis type 1, 4.2% a Denis type 2, 0% a Denis type 3, 43.3% a Denis type 1-2 and 10.1% a Denis type 1-2-3 fracture zone. FFP type II a to II c fractures were found in 88.2%, FFP type III c in 7.4% and FFP type IV b in 4.4%. Bilateral FFS were found in 68.8%. The average bone mineral content (BMC) was 35.4 (2-74) mg/ml, and the average vitamin D value was 8.8 (0-28) nmol/l. Other osteoporosis-associated fractures were found in around 50% of the patients. After CSP, patients showed a rapid and significant (p < 0.001) reduction in pain and…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 68 participants or records.
