Laboratory Studies

The choice of laboratory studies depends upon the medical history of the patient. Routine presurgical labs may include CBC counts, electrolytes, and prothrombin time (PT)/activated partial thromboplastin time (aPTT).

CBC counts may be indicated for a patient with a history of anemia or infection. Electrolyte levels may be indicated for a person taking diuretics. A glycosylated hemoglobin A1C (HbA1C) level to determine glycemic control should be obtained in patients with diabetes mellitus to determine potential wound healing issues. Patients with a bleeding disorder or who are taking warfarin should have their coagulation profile (PT, international normalized ratio [INR], aPTT) checked.

Nutritional labs including albumin, prealbumin, and transferrin levels should be considered if bariatric surgery as been performed or if malnourishment is considered.


Imaging Studies

For complex traumatic or congenital deformities, a CT scan with 3-dimensional modeling can be extremely useful for preoperative planning. Medical models can be generated, allowing the creation of custom-made implants, in particular cases.
