Small injuries that are easily overlooked, such as abrasions, stab wounds, reverse peeling and cuts, can sometimes cause serious infections in the hands.

Diagnosis

Differential diagnosis

Differential diagnosis of redness and swelling of the back of the hand:

1. Hard edema of the palm: Hard edema of the palm is local edema caused by inflammation of the palm tissue due to trauma, infection, autoimmune and other factors. For various reasons, some edema will last for more than one month to 1-2 years. The post-injury edema lasts for more than 6 weeks without regressive tendency. It is called sustained edema, and some of the cases are rich in protein, which will accumulate a large amount of cellulose, which will form scar tissue together with inflammatory hyperplasia. Make the skin harder under the skin. That forms "hard edema."

2, finger frozen: finger frozen is the early symptoms of frostbite. The hands, feet and auricle are the distal part of the human blood circulation and are the predilection sites of frostbite. After the late autumn, the temperature suddenly decreased and the blood flow in the peripheral blood vessels became slow. When the temperature is lower than 10 degrees Celsius, the subcutaneous arterioles in the above-mentioned parts are contracted by cold, and the venous return is not smooth, thereby causing frostbite. Some patients also induce frostbite due to congenital variability of blood vessels and narrow blood vessels leading to poor blood flow.
