Study Notes
Study Guide for IFS-2 Comprehensive Exam
- Exam Structure: The exam covers units 1-7, with units 6-7 comprising 40-50% of the IFS-2 portion. Students should not underestimate the importance of any unit, even those with fewer items. Mastery of biomechanics, neuroanatomy, gross anatomy, and physiology are essential for upper-level courses.
Foot and Ankle Joints (Units 6-7)
-
Joint Overview: This section focuses on the joints of the foot and ankle, including the talocrural, subtalar, transverse tarsal, metatarsophalangeal (MTP), and calcaneocuboid joints. Understanding their locations and functions is crucial for the exam.
-
Joint Structure: Examining the joints in detail from proximal to distal:
- Talocrural joint: Formed by the tibia, fibula, and talus, it enables dorsiflexion and plantarflexion.
- Subtalar joint: Located between the talus and calcaneus, supporting inversion and eversion of the foot.
-
Transverse tarsal joint (Chopart's joint): A primary stabilizer for uneven terrain, with talonavicular and calcaneocuboid joints.
- Closed Chain Movement: Rearfoot pronation/Forefoot supination.
- Distal intertarsal joints: Include important joints like the cuneonavicular joint and others.
- Forefoot joints: Covering tarsometatarsal joints (supporting foot stability, especially for push-off), intermetatarsal joints, metatarsophalangeal joints, and interphalangeal joints.
Innervation of the Leg (Unit 3)
-
Nerve Pathways: Review and understand the pathways of the obturator nerve, sciatic nerve branches (common fibular and tibial nerves), and their role in innervating muscles throughout the lower limb; this includes cutaneous innervation to the foot.
-
Muscle Compartments: Focus on the specific nerves innervating muscles within each compartment of the lower limb.
Biomechanics and Arthrokinematics (Unit 4)
-
Ankle/Foot Movements: Understanding the planes and axes of dorsiflexion, plantarflexion, inversion, and eversion is essential, along with their open-chain and close-chain kinematics.
-
Ligaments: Be sure to review the function of the ligaments, including their role in static and dynamic stability of the joints.
- Ankle: Anterior Talofibular, Calcaneofibular, Posterior Talofibular, and Deltoid Ligament.
- Foot: Long plantar ligament, plantar calcaneocuboid and plantar calcaneonavicular (spring) ligament, supporting the medial longitudinal arch.
Other Important Aspects
- Muscle Actions: Thorough knowledge of the muscles in the lower leg and their actions (flexion, extension, adduction, abduction, and rotation) is vital for understanding the movement of the foot and ankle. Be aware of which nerves control each muscle group.
- Nervous System Involvement: Review how the autonomic nervous system (sympathetic and parasympathetic) and spinal nerves influence the foot and ankle.
- Blood Supply: A crucial area of study; familiarize yourself with the arteries (anterior and posterior tibial, dorsalis pedis, lateral and medial plantar) and their roles in blood flow to the lower extremities.
- Additional Areas: Important considerations are the basics of ECGs and the blood supply to the heart.
