Abstract: Objective To introduce the experience and technical key points of using suture anchors and absorbable screws in the treatment of displaced greater tuberosity fractures of the humerus through the deltoid approach, and to evaluate the clinical efficacy. Methods From March 2017 to December 2018, 16 patients with displaced greater tuberosity fractures of the humerus were treated with suture anchors and absorbable screws through the deltoid approach. There were 5 males and 11 females with an average age of （61.7±13.3） years. All patients underwent shoulder X-ray and CT examinations before operation, and the greater tuberosity fracture displaced more than 5 mm was considered as a surgical indication. The average time from injury to surgery was 3 d. Functional exercise was started 1 week after surgery. The X-ray films were reexamined every 4-6 weeks, and the shoulder function was evaluated using the Constant-Murley score and the Dash score at follow-up visits 6 months later. Results All patients were followed up for 3-10 months, average （6.9 ± 2.2） months. As of the last follow-up, all of the 16 patients showed bone union, and there were no complications such as nonunion, wound infection, rotator cuff tear, or suture anchors loosening and withdrawal. The shoulder function recovered well, with a Constant-Murley score of 89.3±6.05 and a Dash score of 5.4±3.1 on average. Conclusion It is effective to use suture anchors and absorbable screws to treat large tuberosity fractures of the humerus through the deltoid approach. The economic absorbing materials can prevent secondary surgery and produce small trauma. The method is a good choice for the treatment of large tuberosity fractures of the humerus.
