The goal of this observational study is to learn the outcome of proximal humerus fracture surgery in patients who had it delayed due to COVID infection and compare it with normal patients with same fracture and treatment. The main question it aims to answer is:

• Do the patients with proximal humerus fracture undergoing delayed fixation secondary to COVID infection have the same outcome as that of the normal patients?

The outcome of patients of both group will be assessed objectively via the standard Neer"s shoulder score and compared using independent variable T test.

Inclusion Criteria:

• isolated traumatic proximal humerus fracture (Neer's grading 3 and 4)
• above 18 years of age
• consenting for the study

Exclusion Criteria:

• open fractures: Gustilo Grade II and III
• neurovascular compromise.
• neuromuscular disorders.
• injury severity score >16
• humerus fracture with extension to shaft

both group included patients with isolated traumatic proiximal humerus fracture. The post COVID group included patients with tested COVID positive at presentation. The Non COVID group wire non infected population without COVID infection

only the results will be shared which includes the mean score and p values between groups
