Schwerwiegende Komplikation nach perkutan-transaxillärer Verschraubung einer Glenoidfraktur

Abstract

The common treatment for glenoid rim fractures has been open reduction and internal fixation by a deltopectoral approach. Minimally invasive procedures with percutaneous transaxillary manipulation have a high risk for neurovascular damage. In a single case we demonstrate the possible complications associated with percutaneous refixation of a glenoid rim fracture. A 34-year-old patient with an anterior glenoid rim fracture was referred to our shoulder service after percutaneous transaxillary fixation of the fracture of the glenoid. He presented a dislocated fracture with joint infection and damage of the axillary nerve and artery. During revision surgery, joint infection with Staphylococcus aureus, dislocation of the fracture, aneurysm of the axillary artery, and a lesion in continuity of the axillary nerve were diagnosed. The fragment was excised and the capsule reattached to the remaining glenoid rim. The aneurysm was resected with an end-to-end anastomosis. The outcome was a noninfected and stable shoulder with a limited range of motion. In patients with a glenoid rim fracture with more then 21% of the glenoid fossa involved, refixation of the fracture is recommended. Open reduction and internal fixation is the gold standard. In some cases arthroscopic repair is possible. Percutaneous transaxillary manipulation is not recommended.
