Conservative treatment has the risk of extensor tendon rupture, and for this reason surgery is indicated for persistent tendinitis, as well as for intractable pain. Forearm rotation may be improved after surgery, but this is quite unpredictable. Surgery may involve exploration of the joint, removal of the distal end of the ulna, ulnar shortening, soft tissue joint stabilization, or other procedures. Problems after this type of surgery include a feeling of instability or clunking with motion, which can be troublesome and for which there is no good cure. Another potential problem is weakness and numbness, and there will be a visible scar.
Pain relief is unpredictable.
Range of motion may or may not improve postoperatively. If an extensor tendon rupture occurs from untreated problems, there is a risk of additional extensor tendon rupture.
