A patient is unable to prevent anterior displacement of the femur on the tibia when the knee is flexed. Which of the following ligaments is most likely damaged?

You are performing a musculoskeletal examination on a patient and checking their deep tendon reflexes. When assessing the Achilles tendon reflex, you are testing which of the following nerve roots/spinal cord segments?

nA 51 year-old female hair stylist presents to the clinic complaining of tingling/numbness and “pins and needles” sensations along the sole (bottom) of her right foot. These symptoms become more apparent toward the end of her shift after standing all day in the hair saloon. On examination, the patient has bilateral pes planus (flat feet) and a positive “Tinel sign” when performed along the medial aspect of her ankle. A diagnosis of tarsal tunnel is confirmed. Which of the following nerves is likely impinged within the tarsal tunnel?
tibial nerve - subsequent branches include medial/lateral plantar nerve
patient with flat feet are more likely to develop
tarsal tunnel, due to exaggerated stress along the medial aspect of the ankle/tarsal tunnel area
During inversion ankle injuries…it can contract and avulse a fragment of bone from the base of the metatarsal. One should always palpate the base of the 5th metatarsal when evaluating ankle sprains to rule of the possibility of this injury
fibularis brevis muscle attached to the base of the 5th metatarsal.
