Abstract:
Open reduction and internal fixation are the preferred methods for treating intra-articular fractures of the distal humerus. However, in cases of comminuted fractures, open reduction and internal fixation may result in loss of reduction. Although total elbow arthroplasty can be used as an alternative treatment option, total elbow arthroplasty has several limitations, including excessive bone removal, strict weight-bearing restrictions, polyethylene liner wear, and alterations in biomechanical properties. Elbow hemiarthroplasty is emerging as a novel surgical technique, only the distal end of the humerus is replaced while the proximal end of the ulna and radius is retained. Particularly for patients with high functional demands, elbow hemiarthroplasty may be a viable treatment option. This technique is particularly suitable for young patients with severely comminuted and non-reconstructive intra-articular fractures. Postoperative complications of elbow hemiarthroplasty include elbow stiffness, proximal wear of the ulna and radius, and prosthesis loosening, etc. In some cases, total elbow prosthesis revision is required. Existing research has initially confirmed that elbow hemiarthroplasty has certain advantages in terms of safety and elbow joint function recovery. Additionally, to better accommodate the anatomical characteristics of the Chinese population, customized 3D-printed prostheses based on the contralateral distal humerus and the ipsilateral proximal ulna and radius can be utilized. Further research and development of elbow hemiarthroplasty and novel technologies tailored to the Chinese population should be encouraged to enhance the precise treatment of complex elbow injuries in China.
