Restoring a functional and mobile shoulder following reconstruction of the sternoclavicular joint with a free vascularized fibular(vol 16, page 73, year 2018)

Infection of the sternoclavicular joint (SCJ) is rare and often missed at early stage. In extensive disease with bony and soft tissue destruction, radical excision is indicated. The loss of SCJ results in exposure of vital structures of the anterior mediastinum and instability of the shoulder girdle. SCJ reconstruction using locoregional muscle flaps like the pectoralis major or latissimus dorsi flap has been well described. While these options can provide soft tissue coverage, they do not restore the structural framework of the SCJ which is important for shoulder excursion and chest wall movement. We describe a case of SCJ reconstruction using a free vascularized fibular flap following the resection of sternoclavicular tubercular osteomyelitis. The fibula bone was used to restore the clavicular strut by anchoring it to the remaining manubrium with a steel wire and by plating the lateral end to the remnant clavicle. The steel wire served as a “defunctioning” cerclage that allowed motion of the joint to induce fibrous union. A strict post-operative rehabilitation protocol keeping the shoulder adducted at the initial phase was prescribed. At one year follow up, the patient achieved good shoulder function with 140 degrees of shoulder abduction and 110 degrees flexion. © 2018 The Author(s)
