Injuries to the wrist
Fracture of distal radial epiphysis in kids Fractures of distal radius common in elderly Ligament most at risk - palmar radiocarpal ligament Wrist sprains commonly occur in ligaments of carpal bones
66
Club foot
Congenital Talus bone deformity Shortened and tightened tendons in leg Presents as foot inversion, adduction of foot, plantar flexed
