Abstract
Study design:
Criterion standard and survey cases.
Objectives:
To assess the utility of ultrasonography for detecting deep tissue injury or incipient pressure ulcers and to determine the patterns of development of pressure ulcers in subjects with chronic spinal-cord injury (SCI).
Setting:
Ambulatory setting at public hospital.
Methods:
The subjects were 43 men with SCI between C5 and L1 (age: 42.6
11.6 years, means.d.). A total of 129 areas (sacral region and bilateral ischial regions in each subject) were examined by inspection, palpation and ultrasonography.
Results:
Of the 129 areas, 112 were normal by inspection, palpation and ultrasound imaging. Nine areas were abnormal on ultrasonography alone and six were lesion positive by palpation and ultrasonography. Only two areas were abnormal by all three methods. Ultrasonography always detected a heterogeneous pattern and low-echoic areas directly adjacent to the bone.
Conclusions:
Our results indicated that low-echoic lesions, signaling deep tissue injuries or early pressure ulcers, originated in areas near the bone and extended toward the epidermis. The results suggest that ultrasonography is a useful tool for the early detection of deep tissue injuries or pressure ulcers.
Keywords:
pressure ulcer, inspection, palpation, ultrasonography, deep tissue injury
