RESUMO
We compared two surgical techniques for the treatment of scaphoid non-union, namely, using distal radius vascularised bone graft and iliac crest non-vascularised bone graft. Eighty patients with symptomatic scaphoid non-union underwent surgical treatment, including 35 patients treated with distal radius vascularised bone graft and 45 treated by iliac crest non-vascularised bone graft. Patients were assessed objectively by examination of wrist range of motion, grip strength and radiographic findings in the postoperative period after a mean time of 2.8 (1.4) (range 1-5.2) years. Similar functional results were obtained with the two techniques. All cases of non-union in the non-vascularised group obtained consolidation in a mean time of 8.89 (2.26) months and in the vascularised group in a mean time of 7.97 (3.06) months. Three cases of consolidation failure occurred in the vascularised group and were related to technical difficulties.

The purpose of this non-randomised retrospective study was to compare nerve regeneration after reconnection with silicone tubes with two different strategies. A total of 44 patients with injured median or ulnar nerves in the forearm were surgically treated. In one group of patients, a silicone tube alone was placed in the nerve gap. In a second group, the silicone tube was filled with autologous bone marrow mononuclear cells obtained by aspiration from the iliac crest. Motor function, sensation and the effect of pain on function were assessed 1 year after surgery. The tubes filled with bone marrow cells showed better recovery than the empty tubes. The use of bone marrow mononuclear cells in addition to tube re-connection may promote better nerve regeneration than conventional tubular repair.
