Real-time shear wave elastography for measuring complete rupture of the closed Achilles tendon
Objective To explore the hardness study of shear wave elastography(SWE)on closed complete Achilles tendon rupture.Methods Fifty-three patients with closed complete Achilles tendon rupture diagnosed by ultrasound in the First Hospital of the University of Science and Technology of China from July 2021 to January 2024 were selected,and the separation length of the Achilles tendon rupture,the length of the rupture site from the attachment site and the thickness of the Achilles tendon were measured ultrasonographically,as well as the proximal and distal Achilles tendon rupture and the healthy Achilles tendon shear wave velocity(SWV),and the SWV of the flounder muscle of both the affected and the healthy side were measured simultaneously.Results The 53 cases of closed patients with complete Achilles tendon rupture,62.26%(33/53)of the Achilles tendon ruptures occurred on the left side and 37.73%(20/53)of the Achilles tendon ruptures occurred on the right side.Side-by-side comparisons of the thickness of the ruptured Achilles tendon on the affected side,the thickness of the Achilles tendon on the healthy side,the length of the rupture from the attachment,and the length of the separation of the Achilles tendon on the affected side were not statistically significant(P＞0.05);the thicknesses of the distal part of the rupture of the Achilles tendon on the affected side and that of the Achilles tendon on the healthy side were 8.36±3.07 mm and 5.01±0.97 mm,respectively,with statistically significant differences(P＜0.05),the thicknesses of the proximal part of the rupture of the Achilles tendon on the affected side and the Achilles tendon on the healthy side,the The differences in SWV between the proximal part of the affected Achilles tendon rupture and the proximal part of the affected Achilles tendon rupture and the distal part of the affected Achilles tendon rupture were statistically significant(P＜0.05),and the differences in SWV between the healthy Achilles tendon flounder muscle and the affected ruptured Achilles tendon flounder muscle were not statistically significant(P＞0.05).Conclusion Closed complete rupture of the Achilles tendon mostly involves the left Achilles tendon,and the elastic changes of the affected Achilles tendon occur in the free Achilles tendon and do not involve the proximal tendon structures of the flounder muscle,and the SWE technique can be used to quantitatively assess the preoperative stiffness of the affected Achilles tendon.
