Background: The elbow is the second most commonly dislocated major joint in adults.Elbow dislocation can lead to acute or chronic instability. There are different surgical options and functional outcomes in both cases. The purpose of this study is to assess the functional outcomes and the postoperative complications of these two groups.
Methods: We retrospectively reviewed the functional outcomes of cases of acute and chronic post-traumatic elbow instability that were surgically managed between 2013 and 2016 in adult population. All patients were assessed radiographically and clinically using the Mayo Elbow Performance Score and The Disabilities of the Arm, Shoulder and Hand Score at six months follow-up.
Results: Four male patients were included, two in each group of acute and chronic instability. In Three cases the medial and lateral collateral ulnar ligaments were reconstructed using semitendinosus allograft. In one case the repair of both collateral ligaments was performed usingsuture anchors. Two acute coronoid fractures were managed by using the lasso-type technique and one nonunion treated with two cannulated screws. The mean post operative Mayo Elbow Performance Score were 95 for the acute instability group and 85 for the chronic instability group. The mean Disabilities of the Arm, Shoulder and Hand post operative scores were 5,8 and 18,3 for the acute and chronic instability groups respectively. There was one case of ulnar neuropaxia that resolved spontaneously at two months follow-up. All patients had a reduced and concentric elbow in control radiographs at six months follow-up.
Conclusions: Both groups presented satisfactory results after being managed by different surgical techniques.
