The X-rays were significant for a subtalar dislocation. The calcaneus (red) is laterally displaced with respect to the talar head (orange), and the white lines indicate the normal articular surface. Additionally, there was a talonavicular dislocation, as seen in the fourth image: the talus (green) and navicular bone (purple) overlapping suggests a dislocation. In a normally aligned foot, the boundaries of the two bones create a point of articulation.

The video shows a water bath ultrasound of the right 4th digit, demonstrating soft tissue swelling with a hypoechoic region along the tendon consistent with edema and tendon disruption (see video and annotated still image).

Dorsally-Displaced Metacarpal Dislocation-Fracture

Richard Barnett, DO^* and Richard Brodsky, MD^*

DOI: https://doi.org/10.21980/J8ZW54Issue 3:3 No ratings yet.

A two-view radiograph of the right hand was obtained which revealed a dorsal dislocation of the distal fourth and fifth metacarpals (see red and blue outline, respectively) with a concomitant fracture of the distal fifth metacarpal (see yellow line) and avulsion fracture of the lateral aspect of the hamate (see green line). After reduction the fourth and fifth metacarpal dislocations are resolved; however, the distal fifth metacarpal fracture (yellow line) and avulsion fracture of the lateral aspect of the hamate (green line) are still visible.

The frontal view of the right foot showed divergent dislocation of the second through fifth metatarsal bones (red outlines) consistent with Lisfranc injury. Though the Lisfranc ligament is not visualized by radiograph, the yellow markings represent the location of the Lisfranc ligament between the medial cuneiform (blue dot) and the base of the second metatarsal bone. The first metatarsal and the medial cuneiform remain congruent. The lateral view shows dorsal dislocation of the midfoot (pink circle) consistent with instability. There is associated extensive midfoot soft tissue swelling.

History of present illness: A 69-year-old male presented to the emergency department (ED) with left hip pain after he was rear-ended on his bicycle by a vehicle traveling 10-15 miles per hour. He had normal vital signs. On exam, his left lower extremity was externally rotated and shortened with trochanteric point tenderness. His pelvis was stable. His lower extremity compartments

History of present illness: A 12-year-old male presented to the emergency department with right thumb pain and a mass for four months (see images). He denied fevers, chills, change in appetite, or fatigue. He noted that the lesion was growing and “bleeds easily if bumped.” He denied any trauma to the thumb, except “hitting it” months ago while in football
