We present a sternoclavicular dislocation as a non-reported complication after spinal kyphotic deformity surgical correction.
The sternocostal complex seems to have an important role in the pathology of Scheuermann’s kyphotic deformity. A role for the sternoclavicular complex has never been reported in association with Scheuermann’s disease pathology but could explain anterior sternoclavicular dislocation after spinal kyphotic deformity correction.
A 19-year-old male patient underwent surgery for a 74° thoracic kyphosis associated with a 35° thoracic and a 50° lumbar scoliotic curve. In the early post-operative period, the patient developed pain over the left sternoclavicular joint articulation, with a very obvious lump. An X-ray disclosed an anterior sternoclavicular dislocation. After surgical treatment failed, the dislocation was repaired in a second surgical procedure with a flexion and lengthening osteotomy of the middle third of the clavicle followed by capsular repair reinforced with sternocleidomastoid fascia.
At an 8-year follow-up after his spine procedure and 6 years after his clavicular surgery, the patient had full shoulder range of motion and no joint pain, despite the presence of a new sternoclavicular anterior dislocation.
Sternoclavicular dislocation after spine kyphotic deformity correction is presented for the first time; however, it is not possible to establish a causative association. Additional studies are necessary to delineate the role of the sternoclavicular complex in Scheuermann’s disease.
