Shoulder dislocation is most common large joint dislocation in body. Bimodal sex distribution: 9:1 in 20-30s, 3:1 in 60-80s. Shoulder sacrifices stability for increased function. Glenoid fossa and ligaments make shoulder particularly susceptible
Fibula is slender long bone located below tibia. Average length is 390mm in men and 360mm in women. Contains trabecular bone at ends and compact bone along shaft. Forms part of tibiofibular syndesmosis with tibia and talus
Occurs in 0.5% of ankle sprains without fracture. Most commonly caused by sudden external rotation of ankle. External rotation forces talus laterally and pushes fibula away
Broken leg is a break or crack in leg bones. Treatment depends on severity and location. Severe fractures may require pins and plates. Less severe breaks treated with cast or splint
The forearm consists of two long bones: radius and ulna. The radius articulates with the ulna and scaphoid/lunate bones. The ulna articulates with the radius and the wrist's triangular fibrocartilage disc. The bones are connected by the interosseous membrane
Joints are points where two bones meet, enabling movement and protection. Synovial joints are freely mobile with hyaline cartilage lining. Fibrous joints connect bones with fibrous connective tissue. Cartilaginous joints use cartilage for connection, divided into synchondrosis and symphysis types
