Hand surgery will benefit you if your hand is damaged in some way or the other. It is a very specialized type of surgery. It can treat those conditions that pain your hand. It also treats those conditions that harm your wrists and fingers by weakening their function, strength and flexibility. Usually those conditions occur after trauma or following abnormalities present at birth. Hand surgery is performed to restore the functionality of the hand and fingers back to normalcy. Hand surgery can treat many conditions; of which, the common conditions are described below:

Tendon Injury / Transfer / Reconstruction
This is the most common injury to the hand and fingers following trauma. The ends of a tendon usually retract from the site of original wound after the injury. A hand surgeon finds out these cut ends and restores the shape and strength of the tendon by suturing it in multiple layers. After road traffic accidents, big gaps between the tendon ends may occur, which cannot be sutured together. Tendon reconstruction is performed in these cases. Tendon from other parts of the body is taken and utilized to restore connection between the tendon ends. Alternatively, other tendons in the hand and forearm are redirected to take over the function of the injured or diseased tendons.


Surgery for Carpal Tunnel Syndrome

Patients may present to a hand surgeon with continuous pain or tingling sensation in the hand. It occurs due to pressure on the median nerve when it passes through a tight tunnel present between the wrist and the hand. The only long-term solution for these patients is to relieve the pressure by surgical means. A hand surgeon makes a small incision in the middle of the palm to find the fibrous tissues that cause pressure on the nerve. These fibrous tissues are divided fully in order to relieve the pressure on the nerve. The results take a few days to appear, and are usually long lasting.


Finger and Hand Reconstruction
When there is a big gap in the hand and fingers, it needs to be covered by flaps, skin grafts or both. A hand surgeon may use different local and distant flaps for reconstructing these defects. These enable near normal recovery in function of the hand. Groin flaps; radial forearm flaps with or without segment of bone; islanded local flaps; local transposition flaps are typical examples amongst others. Shown here is the principle behind a neurovascular islanded flap for coverage of difficult finger defects. 


Birth Deformity or Anomaly Repair
Plenty of defects can occur at birth. Joining of the fingers by skin, bones or both is a common condition, called Syndactyly. A hand surgeon separates the two fingers. Some plastic surgery techniques like skin grafting or local flap procedures may be performed. This makes both the separated fingers to have a full range of motion and a near-normal appearance. Growth of fingers is also possible after that.
Another common defect is duplication of fingers, known as Polydactyly. Many types of hand surgery has been described to treat this properly. Macrodactyly is a condition where overgrowth of soft tissues of finger occur. A hand surgeon can reduce the size by operating on the bone and soft tissues.


Dupuytren’s Contracture
It is disease of the hand in which fibrous tissues in the upper parts of the hand become thick. Nodules and bands are formed, which cause bending of the fingers into an abnormal position. It restricts the movement of the fingers, which can be severe in late stages. A hand surgeon opens the skin overlying these thickened fibers and removes all nodules, bands and other thick fibers. Usually, the fingers can be lengthened fully immediately after the operation and maintained as such by physiotherapy.
