Development and Evaluation of the OF Pelvis Score for Osteoporotic Pelvic Ring Fractures - A Retrospective Assessment of Therapy Recommendations for 107 Patients.

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.
