Results: Mean hospital stay was shortened compared with the control group 4.1±0.8 months versus 10±1.0 months). Elbow extension force according to the BMRC scale was 3.8±0.6 in Group A versus 3.5 for the control group and 3.2±0.5 for Group B compared with 2.8 for the control group. Mean active key grip force was 1.8±0.9 kg for Group A versus 1.9 for controls and 0.9±0.6 kg for the passive key grips in Group B versus 0.9 for controls. Functional independence improved postoperatively, the QIF improved from 40.0±18.0 to 55.2±17.0. Discussion: This work demonstrated that a single operation shortens hospital stay without affecting the final outcome and that the brachioradial can be transferred on the flexor pollicis longus for reactivation of elbow extension. In our experience, only 46% of the tetraplegic patients starting a functional surgery programme benefit from reactivation of the elbow and hand. Procedures performed during a single operation allow a more systematic approach.
