machine cutter!

• This was taken during my A&E elective postingA philipino worker accidentally inserted his hand into the meat cutter machine during his work.He entered A&E department with a great pain on his palm and just covered by a thin clothes.he has a opened injury on his palmar surface of his hand.i think there's a complete transection of the flexor tendon of his palm.basically patient can't do a grip action, incomplete flexion, and stiffness of the joints.

Flexor tendons have 5 different zones in the hand, as follows:

• Zone I contains only the FDP tendon and extends from the insertion of the FDP to the insertion of the FDS tendon.
• Zone II is the area once referred to as "no man's land." It is defined as the area extending from the insertion of the FDS tendon to the proximal end of the A1 pulley.
• Zone III is the zone of lumbrical origin in the palm.
• Zone IV is in the carpal tunnel
• Zone V is proximal to the carpal tunnel in the forearm.
