Final answer:
The 2-year mortality rate after a femoral neck fracture is high due to complications from immobilization and surgery. For patients with kidney failure, this risk is even greater because of the added complexities related to their renal condition.
Step-by-step explanation:
The mortality rate after a femoral neck fracture (fx) at 2 years is significantly increased due to various complications. These fractures are particularly common in elderly individuals with osteoporosis, making them prone to such injuries. The immobility associated with these fractures, coupled with the subsequent surgical treatment that typically follows, leads to risks such as deep vein thrombosis, pulmonary embolism, and pneumonia. All these can significantly increase the mortality rate. When considering patients with kidney failure, the already high mortality rate is further complicated. Acute kidney injury can result from surgeries, and patients with this condition experience a high inpatient mortality rate of 35-40 percent. Consequently, patients with femoral neck fractures and concurrent kidney failure may face an even higher risk of mortality due to a combination of surgical risks, immobilization complications, and impaired kidney function.
