The Research About the Function of the Rotator Cuff After Humeral Greater Tuberosity Fractures

Correlation Study of the Effect of Humeral Tuberosity Fractures on Rotator Cuff Function

The purpose of this retrospective study was to investigate the differences in fracture block and rotator cuff function in patients with rotator cuff injuries due to greater tuberosity humerus fractures. Some patients with combined humeral tuberosity fracture and rotator cuff injury can achieve better fracture healing with preservation of acceptable rotator cuff function after 6 months of conservative treatment and rehabilitation. However, other patients require surgery to improve rotator cuff function and relieve shoulder pain and other complications. In this study, two types of patients were followed up at different time points to find out the change of rotator cuff function of the patients. In addition, this study will measure the data related to the fracture bone block on a three-dimensional model created using CT, by which obtaining more accurate measurements than two-dimensional.

Inclusion Criteria:

• Three dimensional construction with mimics(with CT of B30);
• Patients older then 18 years;
• Fracture of the greater tuberosity of the humerus combined with rotator cuff injury

Exclusion Criteria:

• Patients with the presence of neurological disease;
• Open fracture;
