Abstract
ZAIDENBERG, Ezequiel E et al. Injerto óseo vascularizado pediculado del radio distal para tratar la seudoartrosis recalcitrante del cúbito. Rev. Asoc. Argent. Ortop. Traumatol. [online]. 2018, vol.83, n.1, pp.31-37. ISSN 1852-7434.
Introduction: The purpose of this study was to analyze the clinical and radiological outcomes of a series of patients treated with pedicled distal radius vascularized bone graft for recalcitrant ulnar nonunions. Methods: A retrospective study was performed. The inclusion criteria were patients with diaphyseal or proximal ulnar nonunions with bone defects <6 cm, at least three previous surgeries and a minimum follow-up of 2 years, treated with pedicled vascularized bone graft of distal radius. The number of previous surgeries was recorded. Elbow and wrist range of motion, comparative grip strength, and pain using the Visual Analogue Scale, QuickDASH questionnaire and Mayo Clinic score for elbow were evaluated. Results: Seven patients were included. The mean age was 42 years (range 26-64). The average number of previous surgeries was 4 (range 3-7). The mean follow-up was 31 months (range 24-43). All pseudoarthrosis consolidated. The Mayo Clinic score was good in 4 patients, excellent in 2 patients and moderate in one patient. The mean postoperative Quick- DASH score was 13 (range 0-29). Flexion-extension arch of the wrist was 81% of the contralateral. The elbow range of motion was >100° in 5 patients and 50°- 100° in 2 patients. Conclusion: The pedicled vascularized bone graft of the distal radius is an effective alternative for the treatment of recalcitrant ulnar nonunions.
