OBJECTIVE: To compare the clinical efficacies of humeral head prosthesis and internal fixation in the treatment of comminuted proximal humeral fractures.
METHODS: The clinical data were analyzed for the patients with comminuted proximal humeral fractures undergoing surgeries for humeral head replacement or open reduction plus internal fixation in our hospital between January 2002 and January 2009. Constant scores were used to determine the excellent clinical outcome rates in the two groups, and the operating time, blood loss and postoperative motor scores of the shoulder were compared.
RESULTS: Forty patients in the humeral head replacement group were evaluated. According to the Constant scores, excellent outcomes were achieved in 16 patients, good outcomes in 18 patients, moderate in 3 patients, and poor in 3 patients, with an excellent outcome rate of 85%. In the 40 cases receiving open reduction plus internal fixation, excellent outcomes were achieved in 11 cases, good in 13 cases, moderate in 8 cases, and poor in 8 cases, with an excellent clinical outcome rate of 60%. Compared with open reduction plus internal fixation, humeral head replacement was associated with shortened operating time, reduced blood loss and better motor function recovery of the shoulder.
CONCLUSIONS: Replacement of humeral head prosthesis produces better clinical outcomes than open reduction and internal fixation in patients with comminuted proximal humeral fractures, and can promote the short-term functional recovery of the shoulder with minimal surgical complications.
