RESUMEN
PURPOSE: The purpose of this study was to compare clinical and radiographic outcomes and complications for arthroscopy-assisted vs. open reduction and fixation of coronoid fractures in patients with complex elbow fracture-dislocations. METHODS: This retrospective study analyzed patients with complex elbow fracture-dislocations who underwent surgical fixation for coronoid fractures of the ulna from March 2009 to January 2016. Subjects included those who received either arthroscopy-assisted (group A) or open surgery (group O) for coronoid fractures and concurrent reconstruction of the lateral column (radial head and/or lateral ulnar collateral ligament) with follow-up for at least 2 years. Clinical outcomes were assessed using the visual analog scale for pain, range of motion, Mayo Elbow Performance Score, and Disabilities of the Arm, Shoulder, and Hand score at 2 years after surgery. For radiographic assessment, union of the coronoid, development of heterotopic ossification, and arthritic changes were evaluated. We also reviewed surgery-related complications. RESULTS: Twenty-five patients (mean age, 40.0 ± 12.4 years) were enrolled in this study (group A, 15 patients; group O, 10 patients), and there were no statistical differences in baseline data between the 2 groups. Clinical outcomes did not differ between the 2 groups. All fractures were united and that the prevalence of heterotopic ossification and arthritic changes were similar between the 2 groups. However, operation-related complications were more common in group O than in group A (group A, 13.3%; group O, 40.0%), including 1 patient who underwent ulnar nerve neurolysis and anterior transposition at 3 months after the initial operation. CONCLUSIONS: Eliciting fewer complications, arthroscopy-assisted reduction and fixation of coronoid fractures shows union rates and clinical results comparable to open fixation in patients with complex elbow fracture-dislocation.

INTRODUCTION: Proximal humeral fracture-dislocations can occur in high-energy traumas. This injury can be accompanied by a glenoid fracture; however, it is a rare type of complex injury in patients aged under 60 years. MATERIALS AND METHODS: A 53-year-old man presented with a three-part fracture-dislocation of the proximal humerus and a severely comminuted glenoid fracture. For the glenohumeral dislocation and proximal humeral fracture, we performed closed reduction using a threaded Steinman pin and fixation with percutaneous cannulated screws. Using arthroscopy, while maintaining humeral traction with the Steinman pin, the intra-articular glenoid fragments were reduced and then fixed with a buttressing headless screw and one suture anchor. After a 6-week immobilization with a shoulder spica cast, rehabilitation was initiated. RESULTS: We confirmed bony union of the fracture sites after 6 months post-surgery. The patient showed excellent clinical outcomes with a nearly full range of motion without instability CONCLUSIONS: We reported a successful outcome for a complex proximal humeral fracture involving the glenoid using closed reduction and fixation for the proximal humeral fracture and arthroscopic reduction and fixation for the comminuted anteroinferior glenoid fracture.
