Near Infrared Spectroscopy for the Evaluation of Pediatric Forearm Compartment Perfusion After Supracondylar Humerus Fracture
The purpose of this study is to use a device to compare the blood flow in the patient's
injured arm to the patient's uninjured arm. This will help us determine 'normal' readings for
this device for a child's forearm and may in the future help us detect children that have
injured the blood vessels that go to the forearm when they have an elbow fracture. The
patient will be one of approximately 100 people involved in this research project at
Carolinas Medical Center, and the patient's participation will last until the patient is
discharged from the hospital. It is hypothesized that if the blood vessel is uninjured, the
readings on the NIRS device on the injured arm will be equal to the uninjured arm. It is also
hypothesized that if the blood vessel of the injured arm is injured, the readings on the NIRS
device will be different than on the uninjured arm.

Supracondylar humerus fractures (fracture just above the elbow) are common in children.
Supracondylar humerus fractures account for 60% of the elbow fractures in children. Some
supracondylar fractures injure the brachial artery and a small percentage of children present
with an absent radial pulse after supracondylar humerus fracture, and these injuries may
result in insufficient blood flow to the ipsilateral forearm. This can lead to compartment
syndrome and/or ischemic contracture of the forearm muscles, and may result in permanent
disability. Currently, physicians do not have objective data to determine whether or not the
forearm muscles below a supracondylar humerus fracture are receiving adequate blood flow and
must rely on the clinical exam of the wrist and hand distally. The purpose of this study is
to use near infrared spectroscopy (NIRS) to compare the blood flow in the forearm muscle
compartments of an injured arm compared to an uninjured arm. This will provide data to
establish normal readings for this device for a child's forearm, and may then help clinicians
detect children with insufficient perfusion of the forearm muscles after supracondylar
humerus fracture.
