Core Stability (Pilates) 1:00:00 [1]
weight:77.2kg (injured)
MRI Findings:
There is moderate thickening and hyperintensity of the intraosseous component of the Lisfranc ligament, consistent with subacute injury. No fluid filled cleft is visible.
The thin dorsal component of the ligament is also mildly thickened and hyperintense consistent with injury.
The plantar oblique component of the ligament is not clearly seen but there is immature scar tissue in this region.
Alignment of the tarsometatarsal joints appears maintained.
There is low grade bone marrow oedema of the base of the 2nd metatarsal and of the overlying middle cuneiform, and there is patchy oedema of the medial cuneiform.
There is moderate localised subchondral bone oedema on both sides of the medial cuneiform joint, associated with full thickness cartilage loss and an area of subchondral cyst formation.
The interosseous ligament between the medial and middle cuneiforms is mildly thickened and hyperintense.
The appearances indicate a line of force through the Lisfranc ligament, the medial and middle cuneiforms, and the medial cuneiform/navicular articulation.
No widening of joint spaces nor interosseous distances is visible. No fracture line is seen.
Subacute injury to the three components of the Lisfranc ligament, with proximal injury extension to involve the interosseous medial/middle cuneiform ligament, and the articulation between the medial cuneiform and the navicular with full thickness cartilage loss.
Maintained alignment on these non-weight bearing films.
