Consensus for the Use of Weightbearing CT in the Assessment of Progressive Collapsing Foot Deformity.

RECOMMENDATION

There is evidence that the use of imaging aids in the assessment of progressive collapsing foot deformity (PCFD). The following conventional radiographs (CRs) are necessary in the assessment of PCFD patients: anteroposterior (AP) foot, AP or mortise ankle, and lateral foot. If available, a hindfoot alignment view is strongly recommended. If available, computed tomography (CT) is strongly recommended for surgical planning. When CT is obtained, important findings to be assessed are sinus tarsi impingement, subfibular impingement, increased valgus inclination of the posterior facet of the subtalar joint, and subluxation of the subtalar joint at the posterior and/or middle facet.

LEVEL OF EVIDENCE

Level V, consensus, expert opinion.
