Nirschl’s Classification System

Nirschl’s Classification System categorizes elbow injuries, particularly tendinopathies, based on their severity and stage of development. It includes four stages: 1. Stage I involves pain after activity but no loss of function. 2. Stage II indicates pain during activity, affecting performance. 3. Stage III presents with pain at rest and limited activity. 4. Stage IV signifies chronic pain and significant dysfunction. This system helps healthcare professionals diagnose elbow issues and tailor treatment plans by understanding the injury's progression and severity.
