Abstract
Objective To investigate the effect of shortening of the humerus combined with locking plate technology on bone ununion after multiple operations for humeral shaft fractures. Methods From January 2013 to February 2014, 50 patients with bone ununion after multiple operations for humeral shaft fracture were selected, and were given shortening of the humerus combined with locking plate technology without external fixation after operation, and the training for the shoulder joint and elbow joint function was treated. The grade of the shoulder joint and elbow joint function of pretherapy and post-treatment of them was compared. Results All of the operations were completed successfully without infection of incisional wound of postoperation. Follow-up was 6-24 months, all primary healing of incision, the limb shortened 2-6 cm. All the fractures healed, and the healing time was 6-15 months without ant failures of internal fixation. After 8 months of postoperation, the grade of Hss (93.9±5.0) and Con-stant-Murley (92.7±5.7) were higher than those of preoperative, the differences were significant(P<0.05). Conclusions Shortening of the humerus locking plate technology can improve the side shoulder elbow function, and shorten fracture healing time, and may further improve the prognosis. Key words: Shortening of the humerus; Locking plate technology; Humeral shaft fracture; Bone ununion after operation
