Fig. 3 — Representative micro-computed tomography (micro-CT) images of the proximal humerus and quantitative analysis. (A) Schematic illustration of micro-CT for evaluating tendon-to-bone healing; (B–D) micro-CT images of the proximal humerus and quantitative analysis; (E–G): high-resolution micro-CT of the tendon-to-bone interface of the defect group at 3 M, CNS3 group at 3 M, and intact rotator cuff, with 8.5 μm (E) and 0.7 μm (F) resolutions. Significant difference compared with the defect (*), autograft (⁺), and NS (^#) groups, P < 0.05; Significant difference compared with the NS (**), CNS1 (⁺⁺), and CNS2 (^##) groups, P < 0.01; B, bone; BV/TV, bone volume fraction; Tb.N, trabecular bone number; C, cartilage; CNS, crimped nanofiber scaffold; I, interface; NS, nanofiber scaffold; T, tendon.
