Conditions

Femoral Fracture

Brief summary

Fracture of the upper extremity of the femur is a condition whose frequency increases with age. It is a serious disease, with multiple consequences such as a decrease in life expectancy, quality of life and patient autonomy. In this observational study, the investigators wish to evaluate the evolution of the autonomy of very elderly patients operated on for an upper extremity femur fracture as a function of early post-operative anemia.

Inclusion criteria

* Age ≥ 75 years * Patient operated on a fracture of the upper extremity of the femur * Patient, family or close relative who does not object to participation in the study * Patient affiliated to a social security system * Patient who can be monitored as part of the protocol

Exclusion criteria

* Refusal to participate in the study (patient, family or trusted relative) * Patient with support on the operated limb not authorized by the surgeon * Patient with an associated fracture (polytrauma, concomitant trauma to the upper limb...) * Patient with a pathologic fracture * Patient included in Category 1 interventional research (involving a drug or medical device) * Patient deprived of liberty * Patient not affiliated to a social security system

MeasureTime frameDescription
Hemoglobin Rate5 days after surgery
Questionnaire Activities of Daily LivingPre-fractural and 6 months after surgeryFor each question, a point from 0 (worst value) to 1 (best value) is assigned. The total score is 6 points. A loss of autonomy will be defined by the decrease of one or more points in the ADL. Result showed here is the difference of ADL score intra patient
