[Correction of acquired metatarsus elevatus and hallux flexus: technique used in nine cases]. / Technique de correction du metatarsus elevatus acquis avec hallux flexus. A propos de 9 cas.

ABSTRACT

Nine cases of acquired metatarus elevatus or horizontalization of the first metatarsal with hallux flexus (dorsal bunion) were treated surgically associating plantar wedge resection of the base of the first metatarsal or the first cuneiform; distal disinsertion of the long hallux flexor which was then positioned under the base of the first metatarsal and finally fixed on the distal dorsal segment of the metatarsophalangeal capsule; distal disinsertion of the anterior tibial tendon and tenodesis of the posterior tibial tendon. Weight bearing was allowed after pinning for one Month to position the axis of the first ray. Morphological results, recorded at 11 Years follow-up (mean) were satisfactory. There were no recurrent deformations and no residual instability of the first ray. The only observation was a minimal stiffness of the metatarsophalangeal joint with no tendency to degeneration.
