Treatment options are individualized, and include closed or or open reduction and possible ligament reconstruction. Regardless of treatment, most patients lose some elbow extension, although some improvement may occur as late as one year after injury. Periarticular calcification occurs in over 2 out of 3 patients and degenerative arthritis develops in a similar proportion. Some residual pain can be expected in nearly half of patients. Using pain and loss of motion as indices, fair or poor results can be expected in one out of five patients with a simple dislocation and two out of five with an associated fracture. Results are less likely to be good if immobilization is required for more than three weeks.
