Objectives:
The aims of this study were to measure plasma IL 6 and IL 8 in patients with proximal femoral fracture (PFF) during the early phases of trauma and operation and to find out if there was any correlation between these ILs and the post-operative lower limb oedema.
Material And Methods:
Thirty patients with a median age of 81 years were grouped into pertrochanteric fracture (PTF) (n = 16) and femoral cervical fracture (FCF) (n = 14). Plasma interleukin levels were determined on blood samples obtained from the common femoral vein, immediately after hospital admission, 1 h before operation, and post-operatively at 1, 6, 12, 24, 48 h and on the 7th day. Thigh oedema was calculated by the frustum method.
Results:
In the patients with PTF, maximum mean plasma IL-6 and IL-8 values were found, respectively at 24 h (45.12 pg/mL) and 6 hours (21.7 pg/mL) postoperatively. Whereas, in the patients with FCF, it was respectively, at 12 h (33.1 pg/mL) and 6 h (17.0 pg/mL), for IL-6 and IL-8 post operatively. The patients with PTF and FCF had respectively, 34.1% and 27.4% more thigh oedema in the operated limb on the 7th post-operative day as compared to the preoperative oedema volume (p<0.001). No significant correlation could be found between the plasma IL-6 and IL-8 levels and oedema in the operated limb.
Conclusion:
Increased levels of IL 6 and IL 8 suggest ongoing inflammation.

Inflammatory Response
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...
