Introduction and Objectives: Hallux valgus is one of the most frequent causes of consultation seen by the Trauma and Orthopedic Specialist in feet. Many techniques have been described for its treatment, amongst them Keller-Brandes resection arthroplasty, although there are still doubts about its efficacy in young patients.

Materials and Methods: We reviewed a total of 29 patients, 40 feet, in patients under 63 years of age operated using the Keller-Brandes technique. Anteroposterior and lateral X-rays were taken of both feet when weight-bearing and the intermetatarsal, metatarsalphalangeal, interphalangeal angles and proximal articular set angle (PASA) were measured and compared with their preoperative values. The metatarsophalangeal and interphalangeal joint balances were assessed clinically, pain was assessed using a visual analog scale and using the specific OAFAS questionnaire for the metatarsophalangeal joint.

Results: Mean age at surgery was 56 years of age. The follow-up was 6.88 years. Pre and postoperative X-ray measurements were analyzed statistically and no significant differences were found. The mean value obtained using the AOFAS questionnaire was 72.18, whereas pain was quantified at a mean value of 2.7 using the visual analog scale.

Discussion and Conclusions: We have obtained good results using the Keller-Brandes technique as far as residual pain, both of the hallux and of the other lesser toes, and moderate results in relation to mobility of the articulation of the first toe. In spite of these results, we must consider the repercussion and biomechanical results of this technique.
