Aim. The aim of this paper is to present the middle term results obtained with the percutaneous distal osteotomy (PDO) of the first metatarsus.
Methods. The middle term results obtained in 40 patients submitted to a surgical correction by percutaneous distal osteotomy (PDO) for valgus toe are presented. To better evaluate the clinical outcome we have used the American Orthopaedic Foot and Ankle Society (AOFAS) form. Radiographic and subjective results were evaluated by another form with a maximum score of 100, based on: rate of personal acceptance, metatarsal-phalanx angle, interphalanx angle, proximal articular set angle, and sesamoid position.
Results. As to the clinical parameters, positive results (very good, good, moderate) have been obtained in 90% of cases and the same high percentage (93%) of patients’ satisfaction has been observed.
Conclusion. The conclusion is drawn that distal osteotomy of the first metatarsus according to Bosch is a simple, rapid and non-invasive technique which allows loading and discharge the day after surgery
