Fig. 1.633 Interference between the
splint bone (here Mc2) and the SL body is
characterised by soft-tissue thickening in
the space between the ligament and bone.
Here the whole ligament (SL) is enlarged and
heterogeneous. There is marked periosteal
thickening over the second metacarpal
bone (yellow arrow) and diffuse, focal
hypoechogenicity representing oedema and/or
haemorrhage (red arrows).

Fig. 1.634 A subacute, displaced fracture
of the fourth metacarpal bone with traumatic
SL body desmopathy. The SL contains a
large, diffuse lesion on its dorsolateral aspect,
extending over the dorsal aspect (red arrows).
Hypoechogenic tissue (haemorrhage and
oedema) fills the triangle left by the displaced
fragments (yellow arrows). mpa = medial
palmar artery; mpv = medial palmar vein;
Mc3 = metacarpal 3.

Fig. 1.636 Periostitis of the second metacarpal bone
associated with SL body desmitis. The SL is heterogeneous and
there is a focal hypoechogenic area (yellow arrows) in contact

marked periligamentous thickening (arrow) may be difficult to confirm restrictive adhesion formation,
without evidence of damage to the SL. dynamic examination may confirm motion restriction.
