MEGAPROSTHESIS ELBOW REPLACEMENT FOR NON-BONE CANCER: A RARE CLINICAL CASE REPORT
Main Article Content
Abstract
Introduction: Treatment of elbow bone defects is still a huge challenge in orthopedic in order to restore the shape and function of the elbow joint. Bone defect reconstruction is very difficult due to biomechanical complexity of the elbow joint and the poor coverage tissue of this area, so mega-prothesis can be considered the most optimal solution in these cases. Case report: We present a clinical case of mega-prothesis elbow replacement for treatment of bone defects due to very rare traumatic sequelae. 35-year-old female patient with a 3cm bone defect at distal humerus, the elbow joint was completely unstable and could not be active flexion and extension. The Mayo elbow function assessment scale pre-surgery was poor at 45 points. The post-operative follow-up time was 13 months, range of elbow flexed motion was 130 degrees, patient was maximally extension, the forearm pronation and supination were 90 and 70 degrees, respectively. The Mayo score is excellent with 95 points. The patient was completely satisfied with the postoperative results. Conclusion: Our results show that mega-prothesis elbow replacement is a very effective option for cases large elbow bone defects due to trauma sequelae. However, careful preoperative preparation is required for the best outcome.
