Abstract:

BACKGROUND: There are some satisfactory curative effect for the treatment of comminuted osteoporotic proximal humeral fractures with proximal humeral internal locking system, but always following some complications, such as displacement and loosen of internal fixation.
OBJECTIVE: To investigate the clinical effect of proximal humeral internal locking system and minimally invasive injectable graft for the treatment of osteoporotic proximal humeral fractures in elderly patients. 
METHODS: The 50 patients with proximal humeral fractures were randomly divided into two groups: the experimental group (n=29) and the control group (n=21). The experimental group was treated with proximal humeral internal locking system in minimal invasion. The control group was treated with proximal humeral internal locking system in minimal invasion, and augmentation with minimally invasive injectable graft.
RESULTS AND CONCLUSION: The follow-up period was 11-25 months. All achieved fracture healing. There was no significant difference in fracture healing time and the excellent and good rate of shoulder Neer score between two groups. The complication rate and the restoration loss height of the experimental group were lower than those of the control group (P < 0.05). It indicates that proximal humeral internal locking system and minimally invasive injectable graft is an effective method for the treatment of osteoporotic proximal humeral fractures in elderly patients with the advantages of relatively minor trauma, stable fixation, fewer complication, and better function.
