VAS-pain are scored as a 100 mm VAS (0 = no pain; 100 = worse pain ever); grip strength (conducted with the patient's elbow fully extended and the dynamometer's handle in the middle position. Patients will perform three grip tests on the affected arm with a mean score calculated and used for analysis--measure in kg); PGS is patient global satisfaction using a 5 point categorical scale (0 = not satisfied, 5 = fully satisfied); PANF is patient assessment of normal function using a 5 point categorical scale (0 = no return to normal function, 5 = full return to normal function); PGA is physician's global assessment of elbow injury using a 5 point categorical scale (0 = poor patient elbow function and poor pain management, 5 = normal patient elbow function and normal pain management); AE are adverse events reported.

* = p < 0.05 (within groups); @ = p < 0.05 (between groups)
