Background: Distal osteotomy of the first metatarsal is indicated for the surgical
treatment of mild-to-moderate hallux valgus deformity. The aim of this study was to
evaluate the results of a variant of subcapital distal osteotomy of the first metatarsal
with use of a percutaneous technique in mild-to-serious hallux valgus deformity.
Methods: From 2007 to 2008, 23 consecutive percutaneous distal osteotomies of the
first metatarsal were performed for the treatment of painful mild-to-serious hallux
valgus in 17 patients. The patients were assessed with a clinical and radiographic
protocol at a mean of 4.1 months postoperatively. The American Orthopaedic Foot
and Ankle Society (AOFAS) hallux-metatarsophalangeal-interphalangeal scale was
used for the clinical assessment. The lateral release of the first metatarsal coincides
with the incision for the adductor tenotomia before making the distal osteotomy of the
first metatarsal. Immediate support after foot surgery. Results: The mean score on
the AOFAS scale was 94.58 points. The postoperative radiographic assessments
showed a change compared with the preoperative values, in the mean hallux valgus
angle, first intermetatarsal angle, proximal metatarsal articular angle and sesamoid
position and did not develop any infection. Conclusions: The percutaneous technique
appears to be reliable for the correct execution of a distal linear osteotomy of the first
metatarsal for the correction of a painful mild-to-serious hallux valgus deformity. In
some cases the improvement of symptoms is given by the reduction in the
intermetatarsal angle and correct position of sesamoid rather proximal metatarsal
articular angle.
