Introduction: Osteochondroma is the most common benign tumor of bone. Tumors are metaphyseal in origin and commonly involve distal femur, proximal tibia, and proximal fibula in the lower extremity. Osteochondroma located at proximal fibula can change the normal path of nerves and it may lead to the compression of vessels or peroneal nerve, leading to paralysis.
Case report: We are reporting a case of an 18-year-old female with proximal fibular osteochondroma causing splitting of common peroneal nerve without any neuropathy.
Conclusion: We strive to make the surgeons aware that, when removing osteochondroma located at proximal fibula, care should be taken to identify the entire nerve at the site of lesion before the removal as a procedure done in a hurry in such a case can cause irreversible damage to the patient.
