     Short Answer Key

     1. The ankle joint is formed by the talus, tibia, and fibula. It is a uniaxial joint, primarily allowing dorsiflexion and plantarflexion.
     2. An inversion sprain happens when the foot turns excessively inward, stretching or tearing the ligaments on the lateral side of the ankle. The most commonly affected ligaments are the anterior talofibular, calcaneofibular, and posterior talofibular ligaments.
     3. Repeated sprains are more likely because the initial injury weakens the ligaments, making them less effective at stabilizing the joint and preventing further inversion.
     4. Signs and symptoms of an acute sprain include pain, swelling, tenderness over the affected ligaments, difficulty weight-bearing, and potential bruising.
     5. Palpation helps locate the areas of pain and tenderness, identify swelling, and assess the integrity of the ligaments by feeling for any gaps or abnormal movement.
     6. An X-ray can rule out the possibility of an avulsion fracture where the ligament has pulled off a piece of bone, or a crush fracture on the medial side due to bone compression.
     7. The main goals of manual therapy for acute sprains are to reduce pain and inflammation, manage muscle spasm, and promote lymphatic drainage to reduce swelling.
     8. In chronic cases, the focus shifts towards restoring joint mobility, addressing muscle tightness and trigger points, and strengthening the eversion muscles to compensate for ligament laxity.
     9. RICE stands for Rest, Ice, Compression, and Elevation. Rest minimizes stress on the injured tissues. Ice reduces pain and inflammation. Compression limits swelling. Elevation helps drain excess fluid from the area.
     10. Strengthening the evertor muscles helps compensate for the weakened ligaments and provides better support for the ankle. Proprioceptive training improves the body’s awareness of joint position and reaction time, reducing the risk of future sprains.

     Essay Questions

     1. Discuss the factors that contribute to the high incidence of inversion ankle sprains.

     3. Analyze the importance of a thorough assessment in developing an effective treatment plan for an ankle sprain.
     4. Explain how manual therapy techniques can address the various stages of healing in an ankle sprain, from acute to chronic.
     5. Discuss the long-term implications of an ankle sprain and the strategies that can be implemented to prevent re-injury and maintain ankle function.

Glossary of Key Terms

• Ankle Sprain: A traumatic injury resulting in tearing of ligaments of the ankle joint.
• Inversion Sprain: The most common type of ankle sprain, occurring when the foot excessively turns inward.
• Anterior Talofibular Ligament: A ligament on the lateral side of the ankle that is most commonly sprained in inversion sprains.
• Calcaneofibular Ligament: A ligament on the lateral side of the ankle, providing stability against inversion.
• Posterior Talofibular Ligament: A ligament on the lateral side of the ankle, supporting the joint during plantarflexion.
• Laxity: The looseness or instability of a joint due to stretched or torn ligaments.
• Eversion Muscles: Muscles that turn the foot outward, including the fibularis longus, brevis, tertius, and extensor digitorum longus.
• Ecchymosis: Bruising, discoloration of the skin caused by bleeding underneath.
• Palpation: Examination by touch, used to locate pain, swelling, and tissue changes.
• Passive ROM: Range of motion assessed by a therapist moving the joint without the patient’s active participation.
• Avulsion Fracture: A fracture where a ligament or tendon pulls a piece of bone away.
• Effleurage: A gliding massage stroke used to reduce swelling and promote lymphatic drainage.
• Cryotherapy: Application of cold therapy, often using ice, to reduce inflammation and pain.
• Joint Mobilization: Manual therapy techniques used to restore normal joint movement.
• Proprioception: The body’s awareness of its position in space.
• RICE: Rest, ice, compression, and elevation – a standard protocol for acute injury management.
• Platelet Rich Plasma (PRP): A concentrated solution of platelets derived from the patient’s blood, used to promote tissue healing.
