The focal point of this sqadia.com medical lecture is on the bones and joints of wrist and hands. First and foremost, bones and imaging along with the radiocarpal joint and carpal bones has been elucidated. Furthermore, bases of metacarpals, collateral ligaments of MCP and IP joints have been thoroughly conversed about. Additionally, lesions of upper limb nerves encompassing injuries to long thoracic, axillary and radial nerve together with the injury of median and ulnar nerve has been highlighted.
Bones and Imaging
In this lecture ´´Bones and Joints of Wrist and Hands´´ are explained. Section one is about ´´Bones and Imaging´´. Educator starts this section by giving information about bones and joints of wrist and hands. After that palmar view is discussed. Then dorsal view is elaborated. Following this, carpal bones are elucidated. Subsequently, injuries of hand are focused. In the end, radiograph of hand is exhibited.
Section two is about ''Radiocarpal Joint''. Initially, educator talks about distal ends of radius and ulna showing grooves for tendons. After that articular disc is discussed. Then articular surface of the radiocarpal joint is pursued. Furthermore, ligaments of wrist joints are covered in this part.
Carpal Bones and Bases of Metacarpals
Section three is about ''Carpal Bones and Bases of Metacarpals''. Educator begins by explaining carpal bones in hand. Then carpal bones location is discussed. Likewise, open intercarpal and carpometacarpal (CMC) joints are highlighted. Later on, articular surfaces of the CMC joints are elucidated. Discussion continues on anterior dislocation of the lunate.
Collateral Ligaments of MCP and IP Joints
Section four is about ''Collateral Ligaments of MCP and IP Joints''. Prime emphasis is on the elucidation of extended (MCP) & distal (IP) joints, flexed IP, flexed MCP joint. After that skier’s thumb is elaborated. Then function of hand: grips and pinches are reported. This is followed by hook grasp. Moreover, educator talks about tripod (three-jaw chuck) pinch. later on, fingertip pinch is explained. Loose cylindrical grasp is also covered by the educator. Subsequently, firm cylindrical (power) grasp comes under consideration. Finally, information about disc (power) grasp is delivered.
Lesions of Upper Limb Nerves
Section five is about ''Lesions of Upper Limb Nerves''. At first, injury of long thoracic, axillary and radial nerve is elaborated. Then winged scapula is discussed. Following this, injury of radial nerve is illustrated. Afterwards, injury of median nerve is elucidated. Likewise, educator talks about injury of ulnar nerve.
