Traumatic brachial plexus injury: proposal of an evaluation functional prognostic scoring system

Background: Until now, a scoring system for determining functional prognosis in traumatic brachial plexus injury (TBPI) does not yet exist. Materials and methods: This research is a retrospective study with analytic design to find data for each parameter that affect the functional prognosis in patients with TBPI and assess these factors for comparison using the DASH score. The parameters that are proven to affect the functional prognosis included in a scoring system that we have designed. Results: It resulted that the functional prognosis of TBPI patients can be determined based on the mechanism of injury, initial pain scale, pain time, level of injury, time of surgery, and initial electromyography (EMG) result. Conclusion: Based on the scoring system created in this study, we can conclude that the total score <15 has a good functional prognosis, while a score of ≥15 has a bad functional prognosis, with sensitivity and specificity of 76.6% and 70.2% respectively. This research is categorized as level 3 of evidence.
