The trauma and the operation of femoral fractures provoke a double increase inflammatory reaction. We studied the CRP and how it is influenced form the time and the type of operation. 70 patients, without malignancy or infection, age 80 ± 7 years. The values of CRP were measured on admission, before operation and 48 hours postoperative. The patients were grouped: Group 1: Operation at 1–3 day Group 2: Operation at 4–6 day Group 3: operation after 7 day And in relation with type of operation TGN 23, DHS 19, HEMIARTHROPLASTY 28 The CRP presents a double increase from the trauma to osteosynthesis and at 48 hours after operation. The first moderate increase is presented from the immediate to late osteosynthesis. The second increase is presented at group of late osteosynthesis and TGN>

HEMIARTH. In conclusion the maximum postoperative inflammatory reaction at patients who sustained fractures of femoral neck is measured at 3d and at 6th postoperative day, while before the operation there weren’t any important and statistically differences of CRP values. In comparison with the type and the method of operation, the CRP presents differences between Hemiarthroplasty and (TGN-DHS).
