Coracoclavicular ligaments reconstruction with short lateral peroneal autologous tendon graft

In the dislocation acromioclavicular unstable vertically, the surgical treatment is elementary by the plasty of the ligaments coracoclaviculares, with the purpose of recovering its stability and normal function. There are techniques of a single tunnel in the clavicle or two tunnels (anatomical), with biological or synthetic material. It is a longitudinal prospective experimental study; we included 33 patients between 20 and 50 years of age with diagnosis of complete acromioclavicular dislocation with vertical instability. Reconstruction was performed only of the coracoclavicular ligaments with Mazzocas technique of using autologous tendon graft of the short lateral peroneus. The evaluation of results was with the PENN test. 100% of patients are painless and with an arch of normal shoulder mobility one year after surgery. Radiographically, the coracoclavicular distance compared to the healthy side had an average difference of 1.0 mm at rest and 0.9 mm under load. The reconstruction of the coracoclavicular ligaments with anatomical technique by autologous tendon graft of the short lateral peroneus, allows to recover the acromioclavicular stability and the normal function of the shoulder.
