Modified total elbow arthroplasty for treatment of complex elbow fractures

Abstract

Objective To investigate the method and outcomes of the modified total elbow arthroplasty in the treatment of complex fractures of the elbow. Methods From January 2004 to January 2014, 7 cases of complex elbow fractures were treated with the modified total elbow joint replacement. The results were evaluated by range of motion of elbow flexion/extension, forearm rotation, and by Mayo elbow performance scores. Results All the patients were follow-up for a mean period of 34.6 months (range, 12 to 73 months). Other than ulnar nerve injury in 1 case and heterotopic ossification in 1 case, there were no complications such as infection or loosening of the prostheses. Range of elbow flexion/extension motion increased from (35.71±21.88)°preoperatively to (107.86±11.85)°postoperatively. Forearm rotation range of motion increased from (55.71±32.20)°preoperatively to (72.14±31.07)°postoperatively. The Mayo elbow performance scores increased from 25.71±13.36 to 84.29±12.05 after the operation. All these changes were statistically significant (P<0.05). Conclusion When a suitable prosthesis is chosen, modified total elbow arthroplasty can reduce damage to the bone and soft tissues, speed up postoperative rehabilitation and avoid postoperative complications. It is an effective method for the treatment of complex elbow fractures. Key words: Arthroplasty, replacement, elbow; Fractures, bone; Surgical procedures, operative
