Treatment of post-traumatic complete bony ankylosed elbow using total arthroplasty and hernia patch - A case report.

introduction and importanceThe elbow is one of the most mobile joints, and its movement is very important. Bony ankylosed elbow is an uncommon condition leading to complete loss of activity of elbow, and then lead to severe disability and limitation in activities of daily living. CASE PRESENTATION: A 63-year-old woman sustained comminuted fracture of left distal humerus. She underwent open reduction and internal fixation by plates. After the plates were removed in 2016，stiffness developed.The elbow was stable but fixed at 90°，there was no vascular injury or deficit in sensory and motor function of the ulnar nerve. She hopes to eliminate pain and restore normal mobility compatible with ADL. CLINICAL DISCUSSION: Complete bony ankylosis of the elbow joint may be caused by trauma, rheumatic disease, burns, congenital stiffness and other conditions. Even with the compensation of shoulder and wrist, it will still have a great impact on upper limb function. Whether to treat mainly depends on whether the patient has the require to improve the functionality and return to daily activities. Treatment methods are very limited, including interposition arthroplasty and TEA. Defect of soft tissue appeared was seen in our case, Hernia Patch was innovatively applied to reconstruct the defect of soft tissue and maintain continuity of elbow extension mechanism.

conclusionPatients with post-traumatic elbow joint ankylosis were suffered from severe bony abnormalities, but also soft tissue contracture or defects due to multiple operations and trauma. We present a case of complete bony ankylosed elbow treated with total elbow arthroplasty and Hernia Patch.
