Abstract: Objective To explore the locking plate and acromioplasty in the treatment of greater tuberosity fractures of humerus. Methods 18 cases with fractures of greater tuberosity of humerus treated with locking plate and acromioplasty were retrospectively analyzed. Neer standard was applied to evaluate the recovery of shoulder function, and the X-ray was carried to observe the fracture healing. Results The incisions of all the cases were healed by first intention. All 18 patients were followed up for an average period of 12.5 months(6-18 months)and all patients gained bone union without internal fixation breakage, looseness, shoulder peak impingement syndrome. In the 6-month follow-ups after operation, the shoulder joints of the patients lifting and outstretch were not limited, the patients had not any pain and tenderness in shoulder joints. The functional recovery of shoulder joints on the basis of Neer scoring system was: excellent in 15, good in 3, fair in 0, poor in 0. The excellent and good rate was 100%.Conclusion Using locking plate and acromioplasty in the treatment of greater tuberosity fractures of humerus is an effective technique to prevent shoulder peak impingement syndrome after surgery, at the same time it can promote shoulder joint function recovery.

Key words: greater tuberosity fractures of humerus, locking plate, acromioplasty
