Prevalence of Parkinsonism in Older Patients with Hip Fracture

Parkinsonism in hip fracture (HF) patients is a potential source for complications during surgery, postoperative period and rehabilitation and a risk factor of second HF. We investigated whether parkinsonism was more prevalent in older subjects with HF than in other older patient groups undergoing surgery. We prospectively assessed patients who had suffered HF and controls. We assigned all patients aged 68 and older admitted in our hospital for HF surgery during last year and compared them with age-and gender matched patients attending other surgical departments. 80 HF patients and 80 controls were assessed for parkinsonism. Parkinsonism was common in both groups, presumably reflecting the mean ages of approximately 80 years, plus hospitalization-status. However, parkinsonism was much higher in the hip fracture group (76.25%) compared to the control hospitalised subjects (37.5%; p<0.001). The majority of HF patients with parkinsonism were undiagnosed for their parkinsonism symptoms prior to HF and the same was observed in the control group (91.8% and 86.7% respectively, p= 0.471). Among those with parkinsonism, pre-hospitalization drug therapy may have been contributory in 24.5% of HF patients and 30% of controls (p=0.589). Parkinsonism is very common in older patients admitted for surgery to a general hospital and extremely common in those with HF. It seems that parkinsonism, is heavily under recognised in the elderly. Our data seem to confirm that Parkinsonism is a major risk factor of HF in the elderly.
