Closed Fist Percussion Test

The Closed Fist Percussion Test is a clinical examination technique for detecting vertebral compression fractures. It involves percussing the spine with a closed fist to elicit pain responses.

According to Langdon et al. (2010), the test has a sensitivity of 87.5% and a specificity of 90% for detecting symptomatic fractures of the spine.

Patients presenting with sudden back pain, especially older adults or those with osteoporosis, should undergo this test to screen for potential vertebral compression fractures.
