The employer objected to a Case Manager's decision granting the worker entitlement for a full-thickness rotator cuff tear and a partial-thickness tear of the infraspinatus following a workplace lifting incident.
The Appeals Resolution Officer reviewed the medical evidence, including a pre-accident ultrasound and post-accident MRI.
The Officer found that the full-thickness supraspinatus tear was pre-existing and did not progress as a result of the accident, thereby rescinding entitlement for that condition.
However, the Officer upheld entitlement for the partial-thickness infraspinatus tear, finding it was a new injury compatible with the mechanism of injury.
The employer's objection was allowed in part.
