Fig. 1.645 Chronic entheseopathy of the SL
branch insertion with a combination of new
bone production and defects (widened vascular
channels) (red arrows) leading to the typical
‘sesamoiditis’ appearance on radiographs. Note
the loss of fibre alignment at the SL insertion.

Figs. 1.646, 1.647 Longitudinal frontal plane (1.646) and transverse (1.647) sonograms of the medial branch of the
SL. Chronic desmopathy associated with heterogeneous parenchyma, loss of fibre alignment and periligamentous thick-
ening (dotted yellow line shows extent of SL branch). New bone spurs at the ligament–bone interface (yellow arrows)
represent entheseopathy. Discrete ectopic mineralisation is also present (red arrow) with a hypoechogenic lesion.

Fig. 1.648 Longitudinal sonogram of the
medial SL branch with chronic injury (note the
loss of fibre alignment). Ectopic mineralisation
forms sharp, hyperechogenic interfaces casting
shadowing artefacts at the axial border of the
branch, most likely in the paratenon. Dotted
yellow line = extent of SL branch.
