The goal of this observational study is to validate a risk prediction model developed for unsuccessful elbow flexion recovery after nerve transfer surgery in patients with brachial plexus injury. The main question it aims to answer is how well a risk prediction model perform in a different dataset, which are patients with brachial plexus injury who underwent surgery in a different time period or a different hospital.
