= SHIN SORENESS = MEDIAL TIBIAL STRESS SYNDROME = SOLEUS SYNDROME

= nonspecific term describing exertional lower leg pain

Frequency: 75% of exertional leg pain

Cause: ? atypical stress fracture, traction periostitis, compartment syndrome

Location: posterior / posteromedial tibial cortex

Plain radiographs:

• normal / longitudinal periosteal new bone

• normal radionuclide angiogram + blood-pool phase (DDx to stress fracture)
• linear longitudinal uptake on delayed images

MR:

• marrow edema / hemorrhage
• periosteal fluid
