A hand specialist is a surgeon who diagnoses and treats injuries, diseases, and structural problems affecting the hand, wrist, fingers, and forearm. These doctors complete a full surgical residency (in either orthopedic surgery or plastic surgery) followed by an additional one-year fellowship focused exclusively on the hand and upper extremity. That extra year of training, accredited through the same body that oversees all graduate medical education in the U.S., is what separates a hand specialist from a general orthopedic surgeon or other provider.
Training and Background
Hand specialists come from two different residency paths. Some train in orthopedic surgery, others in plastic surgery. Both groups then compete for the same hand surgery fellowships, and both are qualified to treat the same range of conditions. The difference in background can shape a surgeon’s comfort level with certain procedures (a plastic surgery-trained hand specialist may have more experience with soft tissue reconstruction, for example), but the fellowship year ensures a shared core of knowledge.
Conditions They Treat
The scope of a hand specialist’s practice is broader than most people expect. It covers everything from common overuse problems to rare congenital differences in children.
Nerve Compression
Carpal tunnel syndrome is one of the most frequent reasons people end up in a hand specialist’s office. It results from increased pressure on a nerve at the wrist, causing numbness, tingling, and weakness in the thumb, index finger, and middle finger. A related condition, cubital tunnel syndrome, involves a pinched nerve at the elbow and can produce similar symptoms. Both conditions range from mild and manageable to severe enough to require surgery, and a hand specialist handles the full spectrum.
Arthritis
Osteoarthritis at the base of the thumb is extremely common, especially after age 50. Rheumatoid arthritis can attack the tissue lining the joints and tendons throughout the hand. Either form can make gripping, turning knobs, or typing painful and difficult. Joint stiffness, swelling, and reduced flexibility are the hallmarks, and a hand specialist can offer treatments ranging from splinting to joint replacement.
Tendon Problems
Trigger finger occurs when a finger gets stuck in a bent position and then suddenly snaps straight. De Quervain’s tenosynovitis causes pain at the base of the thumb from inflamed tendon lining. Tennis elbow and golfer’s elbow, which cause pain on the outer or inner part of the elbow with gripping, also fall under a hand specialist’s domain. So do tendon lacerations and ruptures, whether caused by a kitchen accident or a sports injury.
Fractures and Trauma
Broken bones in the hand are common, and the signs include swelling, tenderness, deformity, inability to move the finger, depressed knuckles, shortened fingers, or fingers that point in the wrong direction. Many fractures can be realigned without surgery and held in a cast or splint while they heal. More complex breaks require surgical stabilization. Traumatic finger amputations also fall to hand specialists, who can sometimes repair the injured tissue depending on severity.
Other Conditions
Dupuytren’s disease causes abnormal thickening of the tissue between the skin and tendons in the palm, gradually pulling fingers into a bent position. Ganglion cysts are fluid-filled lumps that grow on the hand or wrist. Hand specialists also treat tumors of the skin, nerves, tendon sheaths, and bone in the hand and wrist, as well as burn and electrical injuries. In children, they address congenital differences like extra fingers, fused fingers, missing thumbs, or duplicated thumbs.
How They Diagnose Problems
A hand specialist visit typically starts with a physical exam, testing your grip strength, range of motion, and sensation. X-rays are the standard first step for suspected fractures or arthritis. For nerve-related symptoms like persistent numbness, tingling, or weakness, the specialist may order nerve conduction studies and electromyography. A nerve conduction study measures how fast and how strongly electrical signals travel along your nerves; a damaged nerve produces a slower, weaker signal. Electromyography checks whether your muscles are responding correctly to those nerve signals, and can detect abnormal electrical activity even when a muscle is at rest. Together, these tests help pinpoint whether your symptoms come from a nerve problem, a muscle disorder, or both.
Non-Surgical Treatments
Surgery is not always the first option. Hand specialists frequently manage conditions with splinting or bracing to restrict movement and let tissues heal. They may recommend specific activity modifications, physical therapy, anti-inflammatory medications, or corticosteroid injections to reduce swelling around a compressed nerve or inflamed tendon. The length of time you’ll need a brace or splint varies by condition, and your specialist will outline a timeline along with any therapy you’ll need.
Surgical Procedures
When non-surgical approaches aren’t enough, hand specialists perform a range of operations. Carpal tunnel release, which relieves pressure on the nerve at the wrist, has a clinical success rate above 95 percent. Tendon repair is more complex because of the tendon’s structure. Repairs can be done immediately after an injury, shortly after, or in a delayed fashion depending on the wound. Nerve repair involves either reattaching the two ends of a severed nerve or using a nerve graft, essentially bridging the gap with nerve tissue taken from another part of the body.
Joint replacement (arthroplasty) is an option for people with severe arthritis that hasn’t responded to conservative care. The destroyed joint is replaced with an artificial one, restoring movement and reducing pain. Hand specialists also perform surgical drainage for deep infections in the hand and wound cleaning (debridement) for severe injuries to prevent infection and promote healing.
Recovery and Rehabilitation
After surgery, hand specialists work closely with certified hand therapists, who are occupational or physical therapists with advanced training in hand and upper extremity rehabilitation. These therapists collaborate directly with the surgeon on wound care, custom splints or braces, and a step-by-step rehab plan. They follow established guidelines for each surgery type, with specific timelines for when to begin exercises and how quickly to progress. This close communication between surgeon and therapist is a defining feature of hand specialty care, and it plays a significant role in outcomes.
Signs You May Need a Hand Specialist
Not every hand or wrist problem needs a specialist, but certain symptoms warrant one. Numbness or tingling that persists in your fingers, especially the thumb and index finger, suggests possible nerve compression. A finger that locks or catches when you bend it points to trigger finger. Pain at the base of your thumb with gripping is a hallmark of de Quervain’s tenosynovitis or thumb arthritis. Joint stiffness and swelling that make routine tasks like opening jars difficult may signal arthritis that benefits from specialized management. And any acute injury involving deformity, an inability to move a finger, or significant swelling should be evaluated promptly.
