Hand injuries and tumors The approach to hand surgery and the required skills are highly variable, with margins ranging from microvascular anastatomosis the design of a bone graft from a specific configuration. A procedure of hand surgery, there is a point denominator special attention to detail, together with a precise technique and gentle, that are necessary to succeed.

Modern advances in magnification, fine structures allow us to repair with better prospects of anatomical and functional reconstruction. The injuries and ailments affecting the hand are many and are based on the different structures that constitute it. 

So traumatic etiology lesions affecting multiple structures, such as the skeleton of the hand in its different segments, can injure any of the phalanges, metacarpals, the carpal bones or bones of the forearm. 

Similarly, injuries often affect the joints of different levels. It likewise injured tendons, both flexors and extensors. Peripheral nerves are also as a frequent site of traumatic injuries. 

Carpal Tunnel 

Carpal tunnel syndrome is a disease more common in women from middle age and can affect one or, commonly, both hands. The patient starts with tingling and numbness of the hand, especially when placed in position long extension (with the wrist bent backward), which usually occurs at night especially in bed. The numbness affects the thumb, index, middle and ring finger part. Over time, and aggravation of the damage, pain can occur in that area, and permanent loss of sensation. 

The cause of this syndrome is compression of a nerve, the median nerve, which, together with another, the ulnar nerve, are responsible for providing sensation to the palm and fingers. Both nerves pass from the forearm to the palm to the wrist by respective tunnels formed between the bones, ulna and radius, and a fibrous taenia keeps in place, along with all the tendons that pass the forearm to the hand the median nerve in the carpal tunnel and ulnar nerve, by that of Guyon. 

Tumors 

Ganglia or synovial cysts are palpable lumps under the skin in the vicinity of a joint, typical locations being the back of the wrist and the back of the knee (popliteal fossa). They occur because the wall of the joint cavity, a chamber filled with a gelatinous fluid called synovial fluid lubricant and allows the joint to slide smoothly during its movement, is a weakness in its wall, and a share of the force exerted on the structure and fluid pressure at this point is giving the wall and forming a kind of balloon outward, which remains connected to the inside of the joint, so that the liquid is still happening to him and making it increasing. It is a completely benign lesion, but sometimes can cause discomfort during joint movement, or limit their travel, for example by extending the wrist backwards or leaning on his hand. 

If the ganglion gives no trouble, it is recommended not to touch it, since the operations to achieve complete removal may not be successful 100%, and frequent recurrence. On the contrary, it is also frequent spontaneous disappearance of the ganglion without surgery, if the liquid flow is reversed and passed back into the joint. But if causes disease, pain or functional impairment, can be removed by surgical repair technique needs only a small incision and regional anesthesia (sleeping only arm).
