Hand surgery is a specialized subspecialty of orthopedics that focuses on the diagnosis, treatment, and reconstruction of diseases, injuries, and congenital deformities affecting the upper extremity—from the fingertips through the hand, wrist, forearm, and elbow.

Because the hand contains a highly complex network of tendons, nerves, blood vessels, and bones, treating this region demands exceptional precision. Hand surgery encompasses everything from acute lacerations caused by occupational, domestic, or traffic accidents to chronic conditions like trigger finger and carpal tunnel syndrome, as well as complex microsurgical procedures such as limb reattachment (replantation).

The primary symptoms indicating the need for surgical intervention or specialized orthopedic care in the hand and wrist include:

• Numbness, Tingling, and Weakness: Loss of sensation, muscle weakness, or a burning sensation that worsens at night (classic indicators of nerve compression).

• Catching or Locking of the Fingers: A snapping or catching sensation accompanied by a clicking sound when flexing or extending the fingers (hallmarks of trigger finger).

• Painful or Painless Swellings: Development of fluid-filled cysts or masses on the wrist or finger joints (ganglion cysts).

• Loss of Motion or Sensation Following Trauma: Inability to move or feel the fingers, or pale, cold fingertips after a laceration or traumatic injury.

• Progressive Hand Deformities: Anatomical changes and joint deformities caused by osteoarthritis or rheumatoid arthritis.

The primary causes of conditions within the scope of hand surgery fall into three main categories:

• Acute Trauma and Accidents: Damage to blood vessels, nerves, and tendons resulting from glass cuts, knife or saw injuries, crush trauma, and wrist fractures caused by falls.

• Overuse and Repetitive Strain: Thickening of ligaments and nerve compression (such as Carpal Tunnel Syndrome) resulting from repetitive hand and wrist movements performed over extended periods (e.g., intensive keyboard typing, manual crafts).

• Systemic Conditions and Congenital Anomalies: Structural deformities caused by systemic joint diseases like rheumatoid arthritis, as well as congenital abnormalities such as webbed fingers (syndactyly) or extra digits (polydactyly).

Due to the complex anatomy of the hand, an accurate diagnosis relies on precise clinical tests performed by a hand surgeon:

• Detailed Physical Examination: Individual sensory perception of the fingers, vascular circulation, tendon function, and muscle strength are carefully evaluated using specialized clinical tests.

• Plain Radiography (X-Rays): Performed as an initial diagnostic tool to evaluate bone fractures, joint dislocations, and the extent of arthritis.

• Electromyography (EMG): The gold standard for determining the severity and exact level of nerve compression in conditions such as carpal tunnel or cubital tunnel syndrome.

• Ultrasonography (US) and MRI: Utilized to visualize tendon tears, ganglion cysts, and soft tissue masses or tumors within the hand.

Treatment in hand surgery is tailored conservatively or surgically based on the patient's functional loss:

• Non-Surgical (Conservative) Methods: For early-stage nerve compression or tendon strain, resting splints, local injections (corticosteroids or PRP), medications, and hand therapy are utilized.

• Surgical Treatments: Procedures such as repairing severed tendons and blood vessels, releasing compressed nerves (carpal tunnel release), and fixing fractures with plates and screws are performed using open or minimally invasive (arthroscopic) surgery.

• Microsurgery: The intricate repair of nerves and blood vessels too fine to be seen with the naked eye, utilizing specialized operating microscopes and sutures thinner than a strand of human hair.

Emergency surgery is required without delay in conditions such as tendon lacerations, nerve transections, open fractures, or traumatic amputations. In chronic conditions (such as trigger finger or nerve compression), non-surgical conservative treatments are typically attempted first.

However, if pain persists despite conservative management, numbness becomes permanent, or muscle atrophy and loss of hand strength begin to develop, surgical intervention becomes mandatory.

Postoperative recovery in hand surgery is exceptionally sensitive and highly dependent on the type of procedure performed. Following minor interventions such as simple nerve decompression or trigger finger release, patients can begin light hand use within a few days. However, after microsurgical procedures involving tendon, nerve, or vascular repair, the hand must be protected in a specialized splint for 3 to 6 weeks.

In hand surgery, regardless of how flawlessly the operation is performed, the single most critical factor determining ultimate success is Hand Therapy. Initiated as soon as the tissue healing permits, a specialized rehabilitation program must be meticulously followed for months to prevent tendon adhesions and restore the hand's intricate fine motor skills.
