Computer aided designed neo-clavical out of osteotmized free fibula: case report

Total. clavicle reconstruction is a challenging task. We performed a reconstruction of the ventral shoulder girdle by calculating a 3D DICOM representation of the left clavicle to create a right neo-clavicle. Two cuts in correct position and angle leads to a natural 3D shape of the new clavicle. The data were used with a thermo-jet procedure to form model slices of thermoplastic wax. Subsequently, the double titanium osteotomy template with correct cut-angulation was constructed. A 40-year old patient presented with symptoms of progressive pain and instability in the shoulder girdle resulting from complete right clavicle resection due to desmoid tumour 23 years earlier. During the operative procedure, dissection, guided double osteotomy, microvascular anastomoses and acromioclwavicular-sternoclavicular fixation were performed. The computer-assisted planning resulted in the exact calculation of the two osteotomy cuts, hence, the 3D appearance of the neo-clavicle. Two years postoperatively, patient showed slightly improved elevation and complete recovery from pain. Our operative procedure demonstrates that the computer-assisted planning with construction of a wax model and an osteotomy template is a useful, approach to plan the two precise cuts leading to a predictable shape of the clavicle.
