The paper presents the surgical technique for Kramer's distal I metatarsal osteotomy and the results of halluces valgi treatment in 23 patients. The mean age of the patients was 48.6 years and mean follow-up time was 4 years and 5 months. Final clinical and radiological evaluation was performed according to Kramer's scale. Excellent and good results were found in 54% of the cases, fair in 32% and bad in 14%. This simple extraarticular osteotomy, without use of any external immobilization yielding three-dimensional correction is a useful method for treatment of hallux valgus.
