Comparative analysis of structural components of hallux valgus deformities by comparing CT-scan and radiographic images

Abstract

Objective: Considering the better imaging definition of the CT-scan and its ability to earlier detect degenerative changes, an accurated evaluation of other parameters, a prospective study comparing RX and CT-scan was performed. Methods: First metatarsophalangeal joint congruency and its degenerative changes, distal metatarsal articular angle (AAMD), first metatarsal head morphology, as well as of the first metatarsocuneiform joint and the dislocation and arthrits changes in the sesamoid bones and crista intersesamoid were evaluated in 20 patients (37 feet). Results: Results did not show significant statistical difference in any of the mensurements. Conclusions: Both methods demonstred similar quality in determining structural and anatomical changes in hallux valgus. The authors concluded that there is no advantage in using CT-scan as a rotine test in hallux valgus evaluation.
