Associated deformities and hypermobility in hallux valgus: an investigation with weightbearing radiographs.
Hallux valgus has been reported to recur after surgical correction in patients subsequently diagnosed with hypermobility of the first ray, pronation of the foot, and pes planovalgus. An objective means of assessing the foot for these deformities preoperatively may avert a poor outcome. This investigation evaluated the efficacy of full-length weightbearing radiographs to recognize associated deformities in patients with hallux valgus before surgery. ⋯ Weightbearing radiographs permit the recognition of associated malalignments of the foot in patients with hallux valgus. The comparisons performed in this study identified deformities consistent with pes planovalgus and hypermobility of the first ray in patients with moderate to severe hallux valgus. The results of our study support a recommendation for a thorough evaluation of full-length, biplanar weightbearing radiographs via the measurement of midfoot and first ray alignment for concomitant deformities of the foot in patients with hallux valgus.
