In chronic palsy (lasting >3-4 months) associated with pain, muscle weakness, or atrophy, surgical outcome is less certain. The duration of entrapment and the severity of numbness and muscle weakness are key factors influencing the prognosis. In these chronic cases, improvement may be limited or even absent after decompression and transposition, but further progression can be halted with proper decompression.
