Small cartilage defects, individual ligament injuries, and longitudinal tendon tears cannot be reliably excluded.\n\n### Abnormal findings\n\n| Location | Description | Confidence |\n|---|---|---|\n| **Subtalar articulation, anterior/middle portion** | Apparent irregular narrowing and indistinctness of the talocalcaneal interface, with intermediate-signal tissue at the articulation. **Suspicious for a nonosseous talocalcaneal coalition**, although the anatomy is not sufficiently resolved to establish this on the supplied images alone. | **Medium** |\n| **Anterior/superior calcaneus adjacent to the abnormal subtalar interface** | Focal fluid-sensitive marrow hyperintensity, most conspicuous in the earlier slices, compatible with reactive marrow edema. Lesser adjacent talar subchondral signal alteration is possible. No definite fracture line. | **Medium** for calcaneal edema; **low** for talar involvement |\n| **Tibiotalar joint** | Small amount of joint fluid distending the recesses. | **Medium** |\n\n### Other structures\n- **Bones/cartilage:** No definite displaced fracture, talar dome collapse, or discrete talar dome osteochondral defect is demonstrated. Cartilage thickness is inadequately resolved for confident grading.\n- **Ligaments:** No definite acute ligament discontinuity identified. The lateral ligament complex and deltoid components are not adequately delineated to confirm or exclude chronic sprain.\n- **Tendons:** No gross tendon rupture seen. No convincing tendon-sheath distention identifiable on these images; individual tendons require assessment in the other planes.\n- **Soft tissues:** No discrete mass or organized collection identified.\n\n**Principal concern:** A possible nonosseous subtalar coalition with adjacent reactive marrow change. Confirmation and precise localization require the full-resolution examination, particularly the sagittal and axial sequences."
