Analysis of the results of M. Maestro procedure in the surgical treatment of hallux valgus

The purpose of the work was to define effectiveness of surgical treatment of patients with hallux valgus deformation with the use of scarf osteotomy in modification of M. Maestro.Based on the analysis of the results of the examination and the surgical treatment using scarf osteotomy in the M. Maestro modification, the reasons for the low effectiveness of this method were revealed in 33 patients with hallux valgus. The use of M. Maestro’s technique allowed us to correct the valgus deviation of the hallux in 57.6 ± 8.6% of patients, to obtain good and excellent functional results in 69.7 ± 8% of patients, and led to recurrence of the disease in 27.3 ± 7,76% of cases. It was found that one of the main causes of hallux valgus recurrence is insufficient correction of PASA during the surgical treatment.The low effectiveness of M. Maestro’s method is associated with obtaining unreliable X-ray values of PASA in planning the method of surgical treatment, with unreasonable application of the M. Maestro technique at high PASA values, with limited possibilities of PASA correction technique.
