Abstract

Abstract : In this paper, our main objective was to emphasize the competency of extended deltopectoral exposure, enforced with the supraspinatus and subscapularis detachment, to gain access to the entire head. The second important point in this paper was to underline the importance of the knowledge that is necessary for interpreting classic radiologic signs of posterior fracture-dislocation of the shoulder. A 47-year-old woman fell down directly onto her shoulder while she was skiing. She was diagnosed with posterior shoulder dislocation, associated with fracture of the head (head splitting) and humeral neck fracture, with the aid of plain radiographs and computed tomographic results. The patient was treated with open reduction and internal fixation of the fracture, through the extended deltopectoral approach, which was augmented with rotator cuff detachment. At the 1-year follow-up, x-rays showed stable fixation with good evidence of healing. One year after the surgery, the patient had no pain, and she regained most of her functionality in her right shoulder with 140 to 150 degrees of lateral elevation (abduction), 140 to 150 degrees of forward flexion, internal rotation hand at T12 vertebra (slightly restricted). These results showed good functionality, with a painless shoulder at the 1-year follow-up. The "double shadow" and "lightbulb" signs are indicative of posterior shoulder fracture-dislocation, and augmented (with the detachment of supraspinatus and subscapularis tendons) traditional deltopectoral incision is suitable for managing these kinds of difficult fracture dislocations.
