“…Malone et al [16] also reported an unresolved dorsal tilt in three of four patients when using volar locking plates. Conversely, Athwal et al [1] reported good radiographic results after the procedure using a 3-D planning and intraoperative navigation system with an optic sensor. Good radiographic results also were achieved in this series with no remaining dorsal tilt.…”

“…The technique has been described in detail previously [17,18,20,22]. The affected and contralateral forearms of all patients were scanned using a CT scanner [1]. Scans were performed with the patient in a prone position with the shoulder at full elevation, elbow at full extension, forearm neutral, and both limbs overhead to reduce radiation exposure to the head and eyes.…”

“…Furthermore, the osteotomy is usually a complex, demanding procedure, and previous studies revealed the rate of residual deformity ranged from 38% to 60% even after operations performed by experienced surgeons [9,25,27]. These findings may be attributed to the fact that malunion of distal radius fractures usually has a three-dimensional (3-D) deformity that sometimes is complex and extensive [1,12]. Two-dimensional evaluation using plain radiographs does not always provide accurate information [1,12,18].…”

Background Corrective osteotomy using dorsal plates and structural bone graft usually has been used for treating symptomatic distal radius malunions. However, the procedure is technically demanding and requires an extensive dorsal approach. Residual deformity is a relatively frequent complication of this technique. Questions/purposes We evaluated the clinical applicability of a three-dimensional osteotomy using computeraided design and manufacturing techniques with volar locking plates for distal radius malunions. Patients and Methods Ten patients with metaphyseal radius malunions were treated. Corrective osteotomy was simulated with the help of three-dimensional bone surface models created using CT data. We simulated the most appropriate screw holes in the deformed radius using computer-aided design data of a locking plate. During surgery, using a custom-made surgical template, we predrilled the screw holes as simulated. After osteotomy, plate fixation using predrilled screw holes enabled automatic reduction of the distal radial fragment. Autogenous iliac cancellous bone was grafted after plate fixation. Results The median volar tilt, radial inclination, and ulnar variance improved from À20°, 13°, and 6 mm, respectively, before surgery to 12°, 24°, and 1 mm, respectively, after surgery. The median wrist flexion improved from 33°b efore surgery to 60°after surgery. The median wrist extension was 70°before surgery and 65°after surgery. All patients experienced wrist pain before surgery, which disappeared or decreased after surgery. Conclusions Surgeons can operate precisely and easily using this advanced technique. It is a new treatment option for malunion of distal radius fractures.

The mechanism of CN cross‐coupling reactions catalyzed by CuI associated to a 1,3‐diketonate ligand L− is investigated by cyclic voltammetry and 1H NMR spectroscopy up to the formation of the key anionic complex [LCuINHCy]−. Its reaction with PhI, shown experimentally, proceeds via an unusual iodide activation, and the transition states are investigated by density functional calculations.
