[Reduction of glenoid rim fractures after primary shoulder dislocation in external rotation].
The treatment of anterior glenoid rim fractures depends on the size of the fracture and the articular surface involved. The operative treatment is open or arthroscopic refixation. In cases with small fragments and a stable shoulder nonoperative treatment is recommended. In patients with a primary shoulder dislocation immobilization in external rotation has been showed to improve the position of the displaced labrum on the glenoid rim. However, whether external rotation can reduce displaced glenoid rim fractures is not known. With the use of CT the repositioning of a glenoid rim fracture in a single patient in external rotation is evaluated.A 26-year-old patient with an anterior glenoid rim fracture after a primary shoulder dislocation was referred to our shoulder service. After initial reduction a CT scan in internal and external rotation of the involved shoulder was performed. In the external rotation CT the glenoid rim fracture was reduced in anatomic position. The patient was immobilized in a 30 degrees external rotation brace for 4 weeks. Six weeks after trauma the internal rotation CT showed the fracture healed in the anatomic position. At the 1-year follow-up the Constant Score and the Rowe Score were 100 points each. In patients with anterior glenoid rim fractures immobilization of the shoulder in external rotation seems to allow a reduction of the fracture. A study with a large number of patients is under way to evaluate long-term results.
