Document Summary
Professor tien nguyen: function and injuries of appendicular skeleton (lower limbs and pelvis) 03. 08. 2017- Flat feet is flattened medial arch due to genetic factors causes issues in knees and pelvis. Natural inversion and slight eversion in all feet regardless of arch flatness. Ankle joints: talocrural joint btwn tibia, fibula, and talus; and subtalar joint btwn talus and calcaneus. Lateral ligaments are most often injured anterior talofibular ligament, posterior talofibular ligament, calcaneofibular ligament; much easier to invert foot than to evert foot. Deltoid ligament (talocrual joint) is thicker and less-likely to be damaged compared to lateral ligaments; can be injured with impact. Gastrocnemius more power and sped (jumping); soleus less intense movements (walking) Knee movements include flexion and extension; more rotation possible with more flexion, rotation isn"t possible with fully extended knee. Popliteus plays part in knee rotation it moves knee out of locked position and allows flexion to occur.
