Fig. 1From: Regenerative effects of platelet-rich plasma releasate injection in rabbit discs degenerated by intradiscal injection of condoliaseRadiographic measurement of disc height. The posterior disc height (D1), middle disc height (D2), and anterior disc height (D3) were measured and calibrated. The disc height (DH) was calculated as (D1 + D2 + D3)/3. Changes in DH were expressed as percentage DH (%DH) and normalized to the measured baseline DH as follows: %DH = (post-injection DH/baseline DH) × 100Back to article page
