AimThe primary aim of this study was to analyze the frequency and characteristic patterns of fall-related fractures as well as consecutive hospitalization and management relating to such fractures. In addition, important pathognomonic and therapeutic aspects are discussed.MethodsThis retrospective mono-center study was conducted at the University Hospital Frankfurt am Main, Germany. Between 2007 and 2017, a total of 145 PD patients with fall-related fractures were identified via a retrospective systematic query in the hospital information system using the ICD-10 German modification codes G20.0-G20.9. Patients with unclear or falsely coded PD were strictly excluded.ResultsThe mean age of the cohort was 77.7 years (± 7.5, median 77.) and 57.9% of the cohort were females (n = 84). A total number of 151 fractures were reported, with 140 patients (96.6%) suffering from one, four patients from two (2.8%), and one patient from three fractures (0.6%) at a time. For 43.9% (n = 65) of the cohort, fractures concerned lower extremities (LE) followed by trunk (38.1%, n = 58) and upper extremities (UE, 17.9%, n = 27). Most common fracture types in LE were femoral neck fractures (52.3%, n = 34). Mean length of hospital stay (LOS) was 13.6 days (95% CI 12.4-14.7). In 43.4% (n = 63) of cases, an interim admission to an intensive-care unit (ICU) was necessary. Mean ICU LOS was 2.3 days (95% CI 1.5-3.0), and mean LOS for normal care unit was 10.5 days (95% CI 10.3-12.4). Surgical treatment was necessary in 75.9% of the cases (n = 110). Patients undergoing surgical treatment showed significantly longer LOS compared to conservatively treated patients (p < 0.001). Moreover, fractures of the LE (p = 0.018) and UE (p = 0.010) were associated with a significant longer LOS.ConclusionFall-related fractures are a common and relevant complication in PD patients leading to increased immobility, frequent hospitalization, and immediate surgical care. Fractures of the lower extremities and trunk were the most common in the cohort for this study. A PD patient presenting to the emergency room or at the general practitioner with a fracture should always be checked for osteoporosis and a fall-related injury should be seen as a red flag for reviewing a patient's individual therapeutic regime.
