About this study
Official title: 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.

Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
classification based on Neer (time frame: 2019.01-2024.8). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Jan 2026.
