Peripheral nerve injuries may have a number of causes, most commonly mechanical. We describe a case of a deep peroneal nerve palsy in an adolescent boy which coincided with a large growth spurt. Spontaneous recovery of full function was seen without intervention.
Conclusion: In the absence of any other causative factors, we believe that this growth spurt resulted in temporary compression of the deep peroneal nerve at the level of the knee producing transient neurapraxia.
