The aim of this study was to assess the functional outcome after lumbopelvic fixation (LPF) using the SMFA (short musculoskeletal functional assessment) score and discuss the results in the context of the existing literature. The last consecutive 50 patients who underwent an LPF were identified and administered the SMFA-questionnaire. Inclusion criteria were:
(1) the patient underwent LPF at our institution,
(2) complete medical records,
(3) a minimum follow-up of 12 months.

The mean age was 60.3 years (32–86 years; 9m/8f) and the follow-up averaged 26.9 months (14–48 months). Six patients (35.3%) suffered from low-energy trauma and 11 patients (64.7%) suffered a high-energy trauma. Patients in the low-energy group were significantly older compared to patients in the high-energy group (72.2 vs. 53.8 years). Five patients (29.4%) suffered from multiple injuries. Compared to patients with low-energy trauma, patients suffering from high-energy trauma showed significantly lower scores in “daily activities” (89.6 vs. 57.1), “mobility” (84.7 vs. 45.5), and “function” (74.9 vs. 43.4).

Results suggest that patients with older age and those with concomitant injuries show a greater impairment according to the SMFA score. Several different outcome scores are used in the mostly small retrospective studies and conclusions should be drawn carefully. However, even though mostly favorable functional outcomes were reported throughout the literature, patients still show some level of impairment and do not reach normative data at final follow-up.
