Researchers in the Orthopaedic surgery department at LSU Medical Center-Shreveport hope to learn if patterns of blood-flow around the incision site of patients undergoing surgery for heel-bone fractures can help predict whether complications will arise after a specific type of operation.The goals of this research study are to effectively answer as many of the following research questions as possible:
- Can a drug normally used to evaluate adequate blood flow in plastic surgery and tissue transfer be used to identify altered patterns of blood flow at the operative site of Calcaneus fractures, when compared to the uninjured extremity?
- Are changes in blood flow identifiable at the operative site post operatively?
- Are there certain patterns of blood flow present preoperatively or postoperatively that can predict wound complication?
- Can certain patterns of blood flow predict the location of slough or dehiscence after surgery?
- Does the incision site and its proximity to specific patterns of blood flow possibly predict wound complication?
The hypothesis is that the study drug will show a correlation between certain patterns of blood flow and whatever post-operative complications may arise.

|Actual Enrollment :||13 participants|
|Intervention Model:||Single Group Assignment|
|Masking:||None (Open Label)|
|Official Title:||Application of Indocyanine Green Angiography for Closed Operative Calcaneus Fractures Requiring Extensile Lateral Incision|
|Study Start Date :||April 2013|

|Study Completion Date :||March 2015|
Experimental: ICG administered
The ICG dose (10 mg/4cc per image capture) will be administered in its entirety via push injection through IV access established for standard surgical procedure, followed by 10 cc Normal Saline bolus. This ICG dose will be administered twice, 1X prior to anesthesia, and 1X after the tourniquet on operative extremity has been removed for at least 15 minutes.
Drug: ICG (Indocyanine Green)
Diagnostic drug used for visualisation of blood perfusion in various tissues.Administered intravenously, 2X: 1X prior to anesthesia, and 1X after tourniquet on operative extremity has been released for at least 15 minutes. When excited by laser light source, it subsequently emits at a near infrared frequency.
