Reduction and fixation of coronoid fractures by arthroscopic surgery

Abstract

Objective To investigate the feasibility and methods of arthroscopic reduction and fixation of coronoid fractures. Methods During 2008 and 2009, 6 patients (4 male and 2 female) with coronoid fractures of Regan and Morrey Types Ⅰ and Ⅱ underwent arthroscopic treatment in our department. Their ages ranged from 19 to 34 years, averaging 26. 6 years. Two fractures involved the left side and 4 the right side. By Regan-Morrey classification, 2 were of type Ⅰ and 4 of type Ⅱ. Standard elbow approaches and the exchange rod technique were applied. Compression screws were used to directly fixate the fracture via the anterior median approach. Results One patient was lost to the follow-up. A mean follow-up of 11 months (7 to 24 months) showed that the other 5 patients achieved a functional range of motion with an average flexion/extension of -2°( - 10° to 140°) and full pronation and supination. No patient had elbow instability and neurovascular complications. All the 5 patients had excellent Mayo elbow performance scores. Conclusion Arthroscopic management of coronoid fractures can provide excellent visual fields for anatomic repair without extensive soft tissue dissection and may thus facilitate early rehabilitation.
