Variations of some plasma components after closed fractures

Area of Science:

• Biochemistry
• Orthopedic Surgery
• Clinical Chemistry

Background:

• Fractures of long bones trigger complex physiological responses.
• Understanding serum protein variations aids in monitoring healing and patient status.

Purpose of the Study:

• To investigate changes in serum total proteins and electrophoretic fractions after uncomplicated long bone shaft fractures.
• To correlate these biochemical markers with the healing process up to 30 days post-trauma.

Main Methods:

• Analysis of serum concentrations of total proteins, albumin, globulin fractions (alpha1, alpha2, beta, gamma), glycoprotein, mucoprotein, fibrinogen, erythrocyte sedimentation rate, calcium, phosphorus, alkaline phosphatase, and acid phosphatase.
• Monitoring these parameters in 25 patients for 30 days following fracture.
• Comparison between upper-limb and lower-limb fractures.

Main Results:

• Significant decrease in albumin and increase in alpha1, alpha2, and beta globulins observed up to 30 days.
• Peak elevations in alpha1, alpha2 globulins, mucoprotein, and fibrinogen occurred on day 10.
• Beta globulin, fibrinogen, and erythrocyte sedimentation rate showed higher and more prolonged elevations in lower-limb fractures.
• Total protein and gamma globulin remained largely unchanged.
• Serum calcium, phosphorus, and phosphatase levels showed no significant variations.

Conclusions:

• Fracture healing involves distinct alterations in serum protein profiles, particularly evident by day 10.
• Beta globulin, fibrinogen, and ESR serve as sensitive indicators of the acute phase response, with limb location influencing their kinetics.
• Routine biochemical markers like calcium and phosphatases are not significantly altered in uncomplicated fractures.
