This research summarized 7 clinical cases of total elbow replacement in 2 male and 5 female patients treated for posttraumatic elbow immobility. Preoperative Mayo elbow performance score  was poor with 49 points. Mean age was 37.2 and mean postoperative observation time was 9 months. After surgery, mean elbow flexion and extension arc gained 110 and 2 degrees respectively, mean elbow range of motion arc was 108 degrees, active forearm pronation and supination arc was 74 and 63 degrees respectively. Mayo elbow performance score was excellent with 94 points. All 7 patients were completely satisfied with the results. Many other reports about elbow replacement treating for posttraumatic restricted elbow movement showed positive results with improvement of elbow range of motion in various degrees. In Vietnam, elbow joint replacement is still a new treatment method. Therefore, it is necessary to have a plan for pre-operative preparation and comprehensive postoperative management of the patients in order to achieve best outcomes.
