Abstract
Motor cycle chain injury occurs when the fingers come between motorcycle chain and sprocket or gears of wheel. It leads to crushing or avulsion injury of the fingers. The force acting on the fingers are compression forces with pulling and rotational components. Initially finger is crushed between chain and the bone, which leads to fracture of the bone then finger is pulled in line of direction of chain leading to rotational injury to distal part of finger while proximal part also undergoes rotation in opposite direction. These two different directional forces act on the same finger produces pulling force which ultimately causes amputation of crushed finger at the site of fracture. In worst case patient himself can be pulled into the gear and chain system sustaining severe damage. This is a case series of fifteen young patients who underwent crush injury of fingers or hand due to motor cycle chain or gear system attached to a machine. We tried to Replant or revascularize all the patients but were successful only in nine patients. In rest six patient we lost the finger, few days after the surgery. We tried to find out the reasons for this failure in spite of successful anastomosis and blood supply of fingers at the time of surgery. We found the reason of failure was the type and force of trauma over fingers. Since these are never sharp cuts, the zone of trauma extends more proximally and distally. Chances of failures of anastomosis increases in zone of trauma. It is also associated with crushing components and fractures. Doing anastomosis away from zone of trauma, by using vein graft, or reducing the length so that end to end anastomosis is possible can lead to decrease in failure rate of Reimplantation. Giving anticoagulants for longer time, improving the micro vascular technique, smaller needle and the suture material, better microscopes and instruments can also make lots of difference in outcomes. To find out reasons for failures of Micro vascular surgery in Motor cycle machine chain injury. How to increase the chances of survival of reimplanted or revascularize traumatized/Amputated fingers.
