Question

A clinician induces contraction of the gastrocnemius and soleus and notices that the foot does not plantar flex as expected. Which of the following would be a logical diagnosis?

Group of answer choices:

Peroneal nerve injury

Ruptured Achilles tendon

Anterior compartment syndrome

Shinsplints

Lateral plantar nerve injury

Answer 1

Option B-Ruptured Achilles tendon

The main symptom of Achilles tendonitis is pain and swelling in the backside of your heel when you walk or run. Other symptoms include tight calf muscles and limited range of motion when you flex your foot.Achilles tendon rupture are unable to stand on their toes or have very weak plantar flexion of the ankle

* peroneal nerve innervates the anterior muscles of the leg by traveling deep to the peroneus longus. This nerve supplies the tibialis anterior, extensor digitorum longus, peroneus tertius, and extensor hallucis longus. These muscles control foot dorsiflexion and toe extension

*Anterior compartment syndrome relates to the big tibialis anterior muscle on the outside of the shin.The "5 P's" are oftentimes associated with compartment syndrome: pain, pallor (pale skin tone), paresthesia (numbness feeling), pulselessness (faint pulse) and paralysis (weakness with movements). Numbness, tingling, or pain may be present in the entire lower leg and foot

*Shin splint affects the tibialis anterior muscle and causes pain along the outside of the shin. ... The tibialis anterior muscle has to work extra hard to be able to dorsiflex the ankle against the tight, strong, plantar flexor (calf).

*Lateral plantar nerve entrapment symptoms

*1.Pain is felt over the inside of the ankle and heel.

*2.Pressing in (palpating) along the inside of foot and ankle, especially near the heel bone is likely to reproduce symptoms.

*3.Sometimes pain may radiate into the middle three toes.

*4.Numbness in the heel is not normally a symptom plantar nerve entrapment.
