Gait Analysis and Biomechanics — Flashcards

Flashcard 1: Inversion of the foot is carried out by?_____

Answer: Tibialis anterior and posterior

Flashcard 2: The _____joint is predominantly involved in plantar flexion and dorsiflexion of the foot.

Answer: tibiotalar 

Flashcard 3: Gluteus _____ muscle is attached to the lateral surface of the greater trochanter.

Answer: medius

Flashcard 4: The _____ nerve (L2-L4 (nerve roots)) provides:- sensory innervation to the anterior thigh and medial leg- motor innervation to the quadriceps, iliopsoas, pectineus, and sartorius

Answer: femoral

Flashcard 5: The _____ and adductor magnus belongs to the medial compartment of the thigh.

Answer: gracilis

Flashcard 6: Medial rotation of the flexed knee is produced by: _____

Answer: popliteus, semimembranosus, and semitendinosus (3)

Flashcard 7: Which nerve gives articular branches to Ankle joint, Tarsal joints, Tarsometatarsal joints and 1st metatarsophalangeal joint?_____

Answer: Deep peroneal nerve

Flashcard 8: The structure marked is the _____ ligament.

Answer: lacunar

Flashcard 9: What are the four primary ligaments of the knee joint?

Answer: 1. Anterior Cruciate Ligament (ACL) 2. Posterior Cruciate Ligament (PCL) 3. Medial Collateral Ligament (MCL) 4. Lateral Collateral Ligament (LCL)

Extra: The ACL and PCL provide anteroposterior stability and are located within the joint capsule (intra-articular). The MCL and LCL provide mediolateral (valgus/varus) stability and are located on the medial and lateral aspects of the joint, respectively.

Flashcard 10: What structures pass deep to the superior and inferior extensor retinacula of the ankle? (List 4 tendons and 1 nerve from medial to lateral)

Answer: From medial to lateral: 1. **Tibialis anterior** (Tendon) 2. **Extensor hallucis longus** (Tendon) 3. **Deep peroneal nerve** (Nerve) (and Anterior tibial artery) 4. **Extensor digitorum longus** (Tendon) 5. **Peroneus tertius** (Tendon) Mnemonic: **T**all **H**imalayas **A**re **N**ever **D**ry **P**laces (Tibialis anterior, Hallucis longus, Artery, Nerve, Digitorum longus, Peroneus tertius)
