RESUMEN
The aim of this study was to develop a simple and reliable score which supports decision making between non-operative and operative treatment in patients with osteoporotic pelvic fractures.Between 2018 to 2020, the OF Pelvis Score was developed during a total of 5 meetings of the Working Group on Osteoporotic Fractures of the Spine Section of the German Society of Orthopaedics and Trauma. The OF Pelvis Score as a decision aid between non-surgical and surgical treatment was developed by expert consensus after analysis of numerous geriatric sacral and pelvic ring fractures from several hospitals. Subsequently, retrospective evaluation of the score was performed on consecutive patients from three hospitals.The following parameters were considered relevant to decision making between non-surgical and surgical treatment and were incorporated into the score: fracture morphology using the OF Pelvis Classification, pain status, level of mobilisation, fracture-related neurological deficits, health status, and the modifiers already integrated into the OF Pelvis classification. If the score is < 8, non-surgical therapy is recommended; if the score is > 8, surgical therapy is recommended; if the score is 8, there is a relative indication for surgery. The OF Pelvis Score was then evaluated retrospectively in a total of 107 patients, according to records. The OF Pelvis Score was 8 points in 4 patients (3.7%), all of whom received surgical treatment. Of the remaining 103 patients, 93 received score-compliant therapy (90.3%). Among these, 4 of the patients who did not receive score-compliant care refused the recommended surgery, so the actual therapy recommendation was score-compliant in 94.2%.The OF Pelvis Score can be used to derive a therapy recommendation in many patients in clinical practice. Because of the possible change of clinical parameters during the course of the disease, the score has a dynamic character. In the retrospective evaluation, the recommendations from the OF Pelvis Score were in close accordance with the therapy actually performed.
RESUMEN
STUDY DESIGN: Multicenter prospective cohort study. OBJECTIVE: The study aims to validate the recently developed OF score for treatment decisions in patients with osteoporotic vertebral compression fractures (OVCF). METHODS: This is a prospective multicenter cohort study (EOFTT) in 17 spine centers. All consecutive patients with OVCF were included. The decision for conservative or surgical therapy was made by the treating physician independent of the OF score recommendation. Final decisions were compared to the recommendations given by the OF score. Outcome parameters were complications, Visual Analogue Scale, Oswestry Disability Questionnaire, Timed Up & Go test, EQ-5D 5 L, and Barthel Index. RESULTS: In total, 518 patients (75.3% female, age 75 ± 10) years were included. 344 (66%) patients received surgical treatment. 71% of patients were treated following the score recommendations. For an OF score cut-off value of 6.5, the sensitivity and specificity to predict actual treatment were 60% and 68% (AUC .684, P < .001). During hospitalization overall 76 (14.7%) complications occurred. The mean follow-up rate and time were 92% and 5 ± 3.5 months, respectively. While all patients in the study cohort improved in clinical outcome parameters, the effect size was significantly less in the patients not treated in line with the OF score's recommendation. Eight (3%) patients needed revision surgery. CONCLUSIONS: Patients treated according to the OF score's recommendations showed favorable short-term clinical results. Noncompliance with the score resulted in more pain and impaired functional outcome and quality of life. The OF score is a reliable and save tool to aid treatment decision in OVCF.
RESUMEN
AIM: Osteoporotic thoracolumbar fractures are of increasing importance. To identify the optimal treatment strategy this multicentre prospective cohort study was performed. PURPOSE: Patients suffering from osteoporotic thoracolumbar fractures were included. Excluded were tumour diseases, infections and limb fractures. Age, sex, trauma mechanism, OF classification, OF-score, treatment strategy, pain condition and mobilization were analysed. METHODS: A total of 518 patients' aged 75 ± 10 (41-97) years were included in 17 centre. A total of 174 patients were treated conservatively, and 344 were treated surgically, of whom 310 (90%) received minimally invasive treatment. An increase in the OF classification was associated with an increase in both the likelihood of surgery and the surgical invasiveness. RESULTS: Five (3%) complications occurred during conservative treatment, and 46 (13%) occurred in the surgically treated patients. 4 surgical site infections and 2 mechanical failures requested revision surgery. At discharge pain improved significantly from a visual analogue scale score of 7.7 (surgical) and 6.0 (conservative) to a score of 4 in both groups (p < 0.001). Over the course of treatment, mobility improved significantly (p = 0.001), with a significantly stronger (p = 0.007) improvement in the surgically treated patients. CONCLUSION: Fracture severity according to the OF classification is significantly correlated with higher surgery rates and higher invasiveness of surgery. The most commonly used surgical strategy was minimally invasive short-segmental hybrid stabilization followed by kyphoplasty/vertebroplasty. Despite the worse clinical conditions of the surgically treated patients both conservative and surgical treatment led to an improved pain situation and mobility during the inpatient stay to nearly the same level for both treatments.
