Photographs taken at the time of the first visit. (a) The left scapula was slightly higher than the right scapula and presented with an atypical medial winging with the arm at the side. (b) The winged scapula became prominent during 0-45  of active flexion.

The distance between the spinal process and medial scapular border was shorter on the left side than the right side at the inferior angle level, but these distances were almost the same at the scapular spine level (Figure 1(a)). The winged scapula became prominent at 0-45  of active flexion, while it disappeared when the patient flexed the left arm while consciously attempting to depress the scapula (Figure 1(b)).
Radiographs showing a small bony fragment on the ventral side of the inferior scapular angle with a narrow space between the fragment and the scapular body to which the superior border was connected by a callus bridge.

Radiographs showed a small bony fragment in the ventral side of the ISA, with a narrow space between the fragment and the scapular body (Figure 2).
Computed tomography at the time of the first visit. (a) Sagittal section revealing that the callus did not connect the fragment with the scapular body. (b) Axial section demonstrating the lateral displacement of the fracture fragment. (c) Three-dimensional reconstruction image showing a bony protrusion ranging from the medial scapular border to the bony fragment, with a narrow break between the protrusion and fragment.

Computed tomography revealed a bony protrusion extending from the medial scapular border to the bony fragment, with a narrow gap between the protrusion and the fragment (Figures 3(a)-3(c)).
Computed tomography at the time of the second visit 4 months later. (a) Sagittal section revealing the disappearance of the narrow space between the fragment and the scapular body. (b) Three-dimensional reconstruction image showing the disappearance of the narrow break between the protrusion and the fragment.

Although the radiographic findings were the same as at the first visit, computed tomography demonstrated bony union (Figures 4(a) and 4(b)).
