Abstract:
Objective: To explore the value of virtual touch tissue imaging quantification (VTIQ) in evaluation of pre-and post-operative elasticity of incomplete acute closed ruptured Achilles tendon in young and middle-age men. Methods: A total of 32 patients with unilateral incomplete acute closed ruptured Achilles tendon were enrolled. VTIQ examination was performed on bilateral Achilles tendon for speed mode. Achilles tendon was divided into distal segment (5 cm above insertion at the attachment of Achilles tendon), middle segment (>5-10 cm above insertion at the attachment of Achilles tendon ) and proximal segment (from >10 cm above insertion at the attachment of Achilles tendon to musculotendinous junction). SWV was obtained, and then statistical analysis was performed in a neutral position 1 week before, 12 weeks and 24 weeks after operation. Results: SWV of ruptured Achilles tendon was lower than that of healthy side (all P<0.001), of distal segment was higher than of middle and proximal segment for bilateral Achilles tendon (all P<0.01). Twelve weeks after operation, SWV of the middle and distal segment of the healing Achilles tendon were both lower than the healthy side (both P<0.001), while 24 weeks after operation, SWV of distal segment of the healing Achilles tendon was lower than the healthy side (P<0.001). SWV of healing Achilles tendon gradually increased with time going, the difference between the two time points is statistically significant (all P<0.01). Conclusion: VTIQ can be used to quantitatively observe the elasticity of incomplete acute closed ruptured Achilles tendon pre-and post-operation, and provide objective evaluation indicators of Achilles tendon.
