Die chirurgische Stabilisierung von Fragilitätsfrakturen des Beckenrings zeigt unabhängig vom Operationsverfahren ein gutes altersentsprechendes Ergebnis
摘要
The treatment of fragility fractures of the pelvis (FFP) is becoming increasingly more important due to the demographic changes. Older age and the associated multimorbidity pose a challenge for the optimal treatment of pelvic fractures.
MethodA total of 36 patients were included. They were categorized according to the FFP classification with the following distribution: 44.4% FFP II, 16.7% FFP III and 38.9% FFP IV. Transiliosacral screws used unilaterally/bilaterally (cannulated 7.3 mm titanium screws with 32 mm thread, MedTech J&J, Umkirch, Germany) were compared to a continuous transiliosacral sacral rod (cannulated 7.5 mm rod, Marquardt, Spachingen, Germany) for stabilization of the posterior pelvic ring (screw vs. rod) and in combination with or without a ventral supra-acetabular external fixator (steel Schanz screws with cross-connectors classified as ⌀Fix vs. Fix). The parameters measured were the duration of surgery, complication and revision rates and functional outcomes. The quality of life on the visual analogue scale (EQ-VAS), EQ-5D-5L index and Elderly Mobility Scale (EMS) were compared 1 day, 6 weeks and 6 months postoperatively.
ResultsThe mean age of the overall cohort was 81.5 ± 7.7 years and the overall mortality rate was 5.6%. The higher complication (29.4% vs. 17.6%, p = 0.419) and revision rates (5.9% vs. 0.0%, p = 0.310) of the screw group were not statistically significant. The EQ-VAS, EQ-5D-5L and EMS showed no significant differences between screw vs. rod. The fix group had a longer operation time (47.2 ± 9.2 min vs. 35.2 ± 20.2 min, p = 0.005) but a lower complication rate (11.1% vs. 28.0%, p = 0.306); however, their mobility was significantly reduced postoperatively and after 6 weeks (EMS day 1: 6 ± 4 vs. 11 ± 4, p = 0.003; week 6: 12 ± 2 vs. 16 ± 3, p = 0.010).
DiscussionOsteoporosis treatment had not been performed prior to the injury in 64.7% of the injured patients, 29.4% received a basic treatment for osteoporosis and 5.9% received specific treatment for osteoporosis. Surgical treatment of FFP II–IV showed a good clinical outcome with age-appropriate values after 6 months. The clinical outcome was the same after 6 months regardless of the surgical procedure.
