Hi, thanks for asking in Healthcare Magic.
Your symptoms could be due to
1. Fracture of metacarpal (MC) bone or phalanges in the left hand.
2. Carpal bones fracture of both hands.
The wrist region of both hands are affected as they have faced the entire brunt of injury
Metacarpals are the long thin bones in the palm/ hand. Fracture of thumb is rare as the bone is quite mobile. The second and third metacarpal bones (index and middle fingers) act as anchors to the other fingers. Fracture of these MC bones or phalanges will prevent the full extension of your fingers. Swelling causes pain in phalangial (digit bones) fracture as there is very limited space in the digit.
Carpal bones are the small bones in the wrist. Among them, Scaphoid and Lunate bone fracture
is more common in outstretched hand injuries. There will be pain and swelling around the wrist in case of fracture of carpal bones.
X-Ray of hand - AP (antero posterior), Lateral and Oblique view (to assess the angulation of fracture fragments as well as the involved joint surfaces) are necessary to determine the extent of lesion. The choice of the treatment depends upon the type of fracture.
If it is a crack fracture immobilization with crepe bandages or casts will help. In case of complete fracture either closed reduction or open reduction with internal fixation
) will help.
You should visit your treating Dr to decide about the further course of treatment.
I hope this is helpful to you.
