Foot Reconstruction Workup
- Author: Fabio Santanelli, MD, PhD; Chief Editor: Jorge I de la Torre, MD, FACS more...
Laboratory Studies
- Obtain a complete blood count (CBC).
- Obtain prothrombin time and activated partial thromboplastin time to check for coagulopathy.
- Check for blood sugar if suggested by anamnesis.
Imaging Studies
- Obtain a chest radiograph if indicated by examination findings or the patient's history.
- Obtain leucocyte lymphoscintigraphy in patients with osteomyelitis.
- Obtain baropodometric evaluation or gait analysis to identify eventual bone functional loss and to plan a repair of the arches.
Computerized baropodometry of the foot. Views of the different pressure levels. - Nuclear magnetic resonance especially is indicated to study ligaments and joints but also to evaluate the soft tissue damage.
Nuclear magnetic resonance of the foot. This examination best shows bone, joints, and ligaments as well as the soft tissues. Nuclear magnetic resonance is important when making the diagnosis in ankle or heel diseases.
Other Tests
- Perform Doppler, echo Doppler, or angiography to assess the vascular pattern of the foot and leg.
- Perform an Allen test in patients with radial free flaps.
- Obtain an ECG in elderly individuals or as per operating room guidelines.
