Unless bilateral movement is required, the normal (uninjured) side is tested first. Answer When evaluating the integrity of ligaments, stress is applied gently and repeated several times; the stress is gradually increased (up to the point of pain) in order that maximum instability can be demonstrated without causing muscle spasm. When individual myotomes are being tested with manual muscle testing, the patient should hold each isometric contraction for at least 5 seconds to determine if any myotomal weakness becomes evident.

is the base of the metatarsal where the fibularis brevis inserts. Avulsion fractures from the pull of this tendon and attached ligaments are characteristic. AVULSION FRACTURES
zone 1 of the 5th metatarsal
is at the metaphyseal-diaphyseal junction, distal to the cancellous (styloid) tuberosity. Fractures, called Jones fractures, are particularly susceptible to nonunion and malunion because this region of the bone has a tenuous blood supply. JONES FRACTURES
