Osteotomy considerations in hallux valgus treatment: improving the correction power.

Efforts are currently being made to improve results in hallux valgus treatment. Different studies to design procedures that are more stable and efficient to correct deformities are underway, and new techniques will be presented in the following years. Better fixation devices will offer reliability in corrections, and hopefully will allow faster rehabilitation with fewer restrictions. Understanding the concept of correction power is important when deciding which technique to use. The origin of hallux valgus is not known, but evidence exists to assume that a correct skeletal and soft tissue balance is important to prevent recurrence and obtain good function. We think that a correct metatarsophalangeal reduction, in which the final position of the hallux is defined mainly by the skeletal alignment and not soft tissues, will dictate the final result. Pushing the metatarsal bone over the sesamoids and not moving the sesamoids under the metatarsal head is a new concept and it may allow better results for our patients. It is hoped that understanding of biomechanics will continue to evolve, and radiological measurements and corrections will produce better functional results for patients.
