<prompt> In forceful inversion of foot, fracture of the tuberosity of 5th metatarsal is due to pull exeed by which tendon?Peroneus longusPeroneus brevisPeroneus teiusExtensor digitorum  <response>: Tuberosity or tubercle at the base of 5th metatarsal gives attachment to the peroneus brevis tendon.The classic Jones fracture is a transverse fracture of the fifth metatarsal at the metaphyseal-diaphyseal junction, just distal to the fouh and fifth intermetatarsal joint. It occurs when a force is applied to a plantarflexed and inveed foot. Peroneus brevis muscle attaches proximally to the upper surface of the fibula; distally, it attaches to the base of metatarsal 5. The fibularis brevis muscle plantar flexes and eves the foot. The superficial fibular peroneal nerve L5, S1, S2 innervates this muscle. Ref: Moon D.A., Foreman K.B., Albeine K.H. 2011. Chapter 37.
