Clinical Trial Summary

The primary objective of the study is to determine in adult patients with a rotator cuff tear, what size and pattern of rotator cuff tear would result in damage to the suprascapular nerve. The secondary objectives are 1. To determine if an injured suprascapular nerve can recover if the rotator cuff tear is surgically repaired. 2. To determine if there is a limit of retraction before the suprascapular nerve is irreversibly damaged. 3. To determine factors that are protective against SSN injury. 4. Can the patient data gathered be used to optimise operative procedures.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Assess suprascapular nerve funaction	MRI scan to quantify size of rotator cuff tear, compared with Nerve Conduction Studies (NCS) to assess suprascapular nerve function.	36 months
Secondary	Shoulder scores	Compare functional shoulder scores to the degree of nerve injury and muscle degeneration over a 24-month period post-injury. Scores to include active range of movement (ROM) measurements; and the collection of validated shoulder outcome scores (DASH, OSS, & Constant score).	36 months
Secondary	Nerve recovery	Functional assessment of nerve recovery at 24 months post-injury for surgically repaired rotator cuff tears.	24 months
Secondary	Machine learning	Use of machine learning to investigate data set for optimum parameters or predictors	24 months
Secondary	Nerve conduction studies	Repeat Nerve Conduction Study investigations at 12 months post injury for all surgically managed participants and non-surgical patients to assess suprascapular nerve function	12 months
