Pearls and Pitfalls of Zone 3 Flexor Hallucis Longus (FHL) Tendoscopy and Metatarsosesamoid Arthroscopy

Pearls	Pitfalls
1. Preoperative clinical examination and investigations are important to determine the structures involved 2. The exploration and debridement is layer by layer from plantar dorsally 3. No arthropump is used to minimize extravasation and spread of infection	1. If lateral sesamoidectomy is indicated, it is better performed through metatarsosesamoid arthroscopy than FHL tendoscopy. The arthroscopic approach allows preservation of a soft tissue envelop of the lateral sesamoid bone and reduces the risk of hallux varus deformity or injury to the lateral digital nerve7
