    Abstract:
    OBJECTIVE: To evaluate the clinical effects of combined methods of minimally invasive percutaneous proximal humeral internal locking system (PHILOS) and injectable bone for the treatment of proximal humerus fractures in elderly patients. METHODS: From January 2006 to January 2012, 80 patients with proximal humerus fractures were randomly divided into two groups (n = 40). The patients in the research group were treated with minimally invasive PHILOS fixation combined with injectable bone, including 20 males and 20 females, with an average age of (68.4 +/- 11.9) years; according to AO classification, 2 cases of type A1, 3 cases of type A2, 6 cases of type B1, 7 cases of type B2, 9 cases of type B3, 6 cases of type C1, 7 cases of type C2. The patients in the control group were treated with PHILOS fixation, including 18 males and 22 females, with an average age of (65.4 +/- 10.7) years; according to AO classification, 3 cases of type A1, 4 cases of type A2, 5 cases of type B1, 8 cases of type B2, 10 cases of type B3, 5 cases of type C, and 5 cases of type C2. The BMD, satisfactory rate, postoperative complications,bone healing time, Constant-Murley score in the two groups were reviewed and compared. RESULTS: In the research group, no patients had necrosis of femoral head, 1 patient had shoulder varus, 1 patient had internal fixation loosening, 36 patients were satisfactory with the treatment results, BMD was (1.013 +/- 0.109) g/cm2, bone healing time averaged (12.00 +/- 3.79) weeks, and the Constant-Murley score was 97.2 +/- 4.6. In the control group, 3 patients had necrosis of femoral head, 5 patients had shoulder varus, 6 patients had internal fixation loosening, 32 patients were satisfactory with the treatment results, BMD was (0.812 +/- 0.089) g/cm2, bone healing time averaged (20.00 +/- 8.67) weeks,and the Constant-Murley score was 78.5 +/- 3.2. The results of BMD, satisfactory rate, postoperative complications, bone healing time, and Constant-Murley score in the research group were better than those of control group (P < 0.05). CONCLUSION: PHILOS combined with injectable bone for the treatment of proximal humerus fractures in elderly patients has advantages of minimal wound, stable fixation, and earlier rehabilitation.
