[A cadaveric study of a new capsulorrhaphy for the surgical treatment of hallux valgus].

BACKGROUND

There are many surgical options for the treatment of hallux valgus in combination with capsular repairs for the correction of hallux valgus.

MATERIAL AND

METHODS

This report corresponds to a descriptive study where a new capsulorrhaphy technique in hallux valgus is proposed. Six dissections were performed on cadavers with hallux valgus deformity using the following surgical technique: medial approach on the first toe longitudinally, dissecting by planes and locating the metatarsophalangeal joint capsule; it was incised longitudinally. The capsule was separated and an exostectomy of the first metatarsal head was done, the edges were regularized and a release of the abductor hallucis was performed. Later, the capsular remnant was resected and repaired.

RESULTS

Six cadaveric feet with hallux valgus were studied, five with mild deformity, one with moderate deformity, one foot with the 2nd finger on supraductus.

DISCUSSION: Many capsular repairs have been reported in the literature, including «L», triangular, «V-Y», rectangular, with satisfactory results, along with osteotomy of the first metatarsal. In this report, a new capsular repair was described.

CONCLUSION

Applying this new capsular repair, we reduced the metatarsophalangeal and intermetatarsal angles and achieved a capsular closure with suitable tension; the metatarsophalangeal joint mobility was preserved.
