Hand Surgery / Reconstruction
Restoring function and form to injured, diseased, or congenitally affected hands
Hand surgery encompasses a wide spectrum of reconstructive and microsurgical procedures designed to restore function, sensation, and appearance to the hand and upper extremity following trauma, disease, or congenital anomalies [1]. The hand is one of the most complex anatomical structures in the human body, containing 27 bones, numerous tendons, ligaments, muscles, nerves, and blood vessels, all within a compact space that must work together with extraordinary precision. Plastic surgeons specializing in hand surgery are uniquely qualified to address the intricate interplay between these structures.
The scope of hand reconstruction includes repair of traumatic injuries such as fractures, tendon lacerations, nerve injuries, and amputations; treatment of degenerative conditions such as carpal tunnel syndrome, Dupuytren contracture, and arthritis; correction of congenital hand differences including syndactyly, polydactyly, and radial club hand; and removal of tumors and cysts. Microsurgical techniques have revolutionized hand surgery, enabling replantation of severed digits, free tissue transfer for complex wound coverage, and nerve repair that can restore meaningful sensation.
The primary goal of hand reconstruction is the restoration of function. The ability to grasp, pinch, manipulate objects, and perform fine motor tasks is essential for daily living, work, and independence. While aesthetic considerations are important, they are secondary to achieving a hand that works well and is free of pain.
Overview
The hand serves as the primary instrument through which humans interact with the physical world. Its complex anatomy allows an extraordinary range of movements, from the power grip needed to swing a hammer to the delicate precision required to thread a needle. When injury, disease, or congenital differences compromise hand function, the impact on the individual's ability to work, perform self-care, and engage in recreational activities can be profound.
Traumatic hand injuries are among the most common reasons for emergency department visits and include fractures, dislocations, tendon and nerve lacerations, crush injuries, burns, and amputations. Industrial accidents, power tool injuries, sports injuries, and motor vehicle crashes are frequent causes. The initial management of hand trauma is critical, as early, appropriate treatment significantly improves long-term outcomes. Delayed or inadequate treatment of hand injuries can lead to stiffness, contracture, chronic pain, and permanent loss of function.
Degenerative and compressive conditions represent another major category of hand surgery. Carpal tunnel syndrome, caused by compression of the median nerve at the wrist, is the most common peripheral nerve entrapment, affecting millions of people and causing numbness, tingling, and weakness in the hand [3]. Dupuytren contracture, a fibroproliferative disease of the palmar fascia, progressively flexes the fingers toward the palm, eventually preventing the hand from opening fully. Trigger finger, caused by thickening of the tendon sheath, creates painful catching or locking of the affected digit.
Congenital hand differences occur in approximately one in every 500 to 1,000 live births [1]. Polydactyly, the presence of extra digits, is the most common congenital hand anomaly [2]. Syndactyly, the fusion of adjacent fingers, is the most common congenital hand malformation requiring surgical correction [1]. More complex conditions include radial longitudinal deficiency (radial club hand), thumb hypoplasia, and constriction band syndrome. Early surgical intervention, typically within the first one to two years of life, can significantly improve hand function and appearance, allowing children to develop normal grasp patterns and fine motor skills.
Tumor surgery of the hand includes excision of benign lesions such as ganglion cysts, giant cell tumors of the tendon sheath, and enchondromas, as well as treatment of malignant tumors including squamous cell carcinoma and melanoma. The challenge in hand tumor surgery is achieving complete excision while preserving maximum function, often requiring reconstruction with local flaps, skin grafts, bone grafts, or prosthetic joint replacement.
Techniques & Approaches
Tendon repair and reconstruction are fundamental hand surgery techniques. Primary repair of acutely lacerated tendons involves meticulous suturing using specialized techniques such as the modified Kessler or cruciate repair, which provide sufficient strength to allow early controlled motion during rehabilitation. When tendons are severely damaged or have retracted, tendon grafting using donor tendons from the forearm or foot may be necessary. Tendon transfers, in which a functioning tendon is rerouted to replace the action of a paralyzed or absent tendon, can restore critical hand functions such as thumb opposition and finger extension in patients with nerve injuries or muscle paralysis.
Nerve repair and reconstruction utilize microsurgical techniques to restore sensation and motor function. Direct nerve repair, performed under operative microscope magnification, involves precisely aligning and suturing the cut nerve ends using sutures finer than a human hair. When a gap exists between nerve ends, nerve grafting using donor nerves, typically the sural nerve from the leg, bridges the defect. Nerve conduits, both synthetic and biological, provide an alternative for short nerve gaps. Nerve transfers, in which a functioning but less critical nerve is redirected to power a more important denervated muscle, have revolutionized the treatment of proximal nerve injuries where traditional repair would require excessive regeneration distances.
Microsurgical replantation involves the reattachment of completely severed digits or hands. Using operative microscopes and instruments, the surgeon systematically repairs bones, tendons, arteries, veins, and nerves to restore viability and function to the amputated part. The decision to replant depends on the level and mechanism of amputation, the condition of the amputated part, and patient factors. Thumb replantation is almost always attempted due to the thumb's critical importance for hand function [2]. Free tissue transfer uses microsurgical techniques to transplant tissue, including skin, muscle, bone, or combinations thereof, from distant body sites to reconstruct complex hand defects.
Treatment of Dupuytren contracture includes open fasciotomy, limited fasciectomy, and percutaneous needle aponeurotomy. Open fasciectomy, the most definitive surgical treatment, involves careful excision of the diseased palmar fascia through zigzag or Bruner incisions. Collagenase injection (Xiaflex) offers a minimally invasive alternative, using an enzyme to dissolve the diseased cord, followed by manipulation to straighten the finger; Xiaflex is manufactured by Endo, Inc. (formerly Endo International), which emerged from bankruptcy restructuring in 2024. Carpal tunnel release, performed through open or endoscopic techniques, divides the transverse carpal ligament to decompress the median nerve [3]. Trigger finger release involves dividing the A1 pulley to eliminate the catching or locking of the affected tendon.
Who Is a Good Candidate?
Ideal Candidates
Ideal candidates for hand surgery include patients with traumatic hand injuries requiring surgical repair, individuals with nerve compression syndromes that have not responded to conservative treatment, patients with Dupuytren contracture causing functional limitation, and children with congenital hand differences. Candidates should be motivated to participate actively in postoperative hand therapy, as rehabilitation is essential to achieving optimal functional outcomes. Non-smokers or those willing to quit smoking heal better and have lower complication rates.
For elective procedures such as carpal tunnel release and Dupuytren fasciectomy, candidates should have exhausted appropriate conservative treatments and have symptoms or contractures that interfere with daily function. Patients with traumatic injuries should be medically stable and have wounds suitable for surgical repair. Children with congenital hand differences are best treated at experienced pediatric hand surgery centers with multidisciplinary teams.
Not Suitable For
Patients with active infections in the hand or upper extremity should not undergo elective hand surgery until the infection is fully resolved. Individuals with uncontrolled medical conditions, particularly uncontrolled diabetes and peripheral vascular disease, face higher risks of wound healing complications and may need medical optimization before proceeding. Patients who are unable or unwilling to participate in postoperative hand therapy are unlikely to achieve good functional outcomes, as rehabilitation is an indispensable component of hand surgery recovery.
Heavy smokers face significantly increased risks of wound healing failure, flap necrosis, and compromised microsurgical results. Patients with severe crush injuries or avulsion-type amputations may have tissue damage too extensive for successful replantation. Elderly patients with multiple comorbidities may be better served by prosthetic fitting than by lengthy reconstructive procedures with uncertain functional outcomes. Patients with unrealistic expectations about functional recovery should be counseled about achievable results before proceeding with surgery.
Risks & Benefits
Benefits
The primary benefit of hand surgery is the restoration of hand function, which directly impacts the patient's ability to work, perform daily activities, and maintain independence. Even partial restoration of grip strength, pinch, and dexterity can dramatically improve quality of life for patients with significant hand disabilities. Successful nerve repair restores protective sensation, preventing the burns and injuries that occur when the hand cannot feel pain and temperature.
Relief of chronic pain and resolution of nerve compression symptoms are among the most immediately gratifying benefits of hand surgery. Carpal tunnel release can eliminate the nighttime numbness and tingling that disrupts sleep, while trigger finger release immediately eliminates the painful catching that interferes with hand use [3]. Treatment of Dupuytren contracture restores the ability to open the hand fully, improving function for activities ranging from washing the face to wearing gloves.
For children with congenital hand differences, early surgical correction allows the development of normal grasp patterns and fine motor skills during the critical period of hand development. The functional and psychological benefits of having a more normal-appearing hand are substantial, facilitating social integration and self-confidence during the formative years.
Risks & Considerations
Hand surgery carries standard surgical risks including bleeding, infection, and adverse reactions to anesthesia. Stiffness is the most common complication and the greatest enemy of hand surgery outcomes. Adhesion formation between repaired tendons and surrounding tissues can limit motion and may require secondary surgery (tenolysis) to release. Nerve repair may result in incomplete sensory or motor recovery, and painful neuromas can develop at the site of nerve injury or repair.
Complex regional pain syndrome (CRPS), a chronic pain condition characterized by burning pain, swelling, and changes in skin color and temperature, can develop after hand surgery or trauma [2]. While uncommon, CRPS can be severely disabling and difficult to treat. Vascular complications, including thrombosis of repaired vessels and digital ischemia, can threaten digit survival after replantation or revascularization procedures.
Tendon repair may fail if the repair ruptures before adequate healing occurs, particularly if the patient does not comply with activity restrictions and therapeutic protocols. Infection is particularly concerning in hand surgery because of the proximity of tendon sheaths, joints, and other structures that can be rapidly destroyed by bacterial infection. Cold intolerance, a common long-term complaint after digital replantation and revascularization, results from damage to the sympathetic nervous system and may persist indefinitely. Malunion or nonunion of fractures, joint contracture, and progressive arthritis are additional potential complications of hand trauma and surgery.
Alternative Procedures
Non-surgical management plays an important role in many hand conditions. Carpal tunnel syndrome may respond to conservative treatment including wrist splinting, activity modification, anti-inflammatory medications, and corticosteroid injections, particularly in mild to moderate cases. Physical therapy and occupational therapy are fundamental to hand rehabilitation, whether as primary treatment for conditions such as mild tendonitis and early stiffness, or as an essential adjunct to surgical intervention.
For Dupuytren contracture, observation is appropriate when contracture is mild and does not limit function. The tabletop test, in which the patient attempts to place the palm flat on a table, is a practical threshold for considering intervention. Corticosteroid injections can reduce nodule size and tenderness but do not prevent progression. Collagenase injection represents a middle ground between conservative management and surgery, though recurrence rates are higher than with surgical fasciectomy. Radiation therapy in the early nodular phase is used in some European centers to slow disease progression.
Custom orthoses and adaptive devices can compensate for lost hand function when surgical restoration is not possible or has been only partially successful. Prosthetic fingers and hands, ranging from simple passive devices to sophisticated myoelectric prostheses, provide functional and cosmetic restoration for patients with amputations. Pain management techniques, including nerve blocks, medications, and neuromodulation, address chronic pain conditions of the hand when surgical intervention is not indicated or has not provided adequate relief.
Preparation & Recovery
Pre-Surgery Preparation
Preparation for hand surgery begins with a thorough evaluation including a detailed history of the hand condition, physical examination assessing range of motion, strength, sensation, and vascular status, and appropriate imaging studies. X-rays are standard for bony injuries, while MRI may be ordered to evaluate soft tissue injuries, tumors, or nerve compression. Nerve conduction studies and electromyography are used to confirm the diagnosis and severity of carpal tunnel syndrome and other nerve disorders.
Patients should inform their surgeon of all medications, supplements, and herbal remedies they are taking. Blood thinners, aspirin, and anti-inflammatory medications may need to be discontinued before surgery as directed. Patients who smoke should stop at least four weeks before surgery to optimize tissue healing and microsurgical outcomes. Preoperative hand therapy may be recommended to optimize range of motion and reduce swelling before surgery.
Arrangements for postoperative assistance should be made, as the operated hand will be splinted and have limited use for a period following surgery. Patients should prepare their home environment by placing frequently needed items within easy reach and arranging for help with tasks requiring two hands. For procedures under general or regional anesthesia, standard fasting guidelines apply and transportation home must be arranged.
Post-Surgery Care
Postoperative care varies depending on the specific procedure performed. The hand is typically immobilized in a splint or cast, with the position determined by the structures repaired. Elevation of the hand above heart level is essential in the early postoperative period to minimize swelling, which is the enemy of hand motion and healing. Pain management includes a combination of elevation, ice applied over the dressing, and medications as prescribed.
Hand therapy, directed by a certified hand therapist working in collaboration with the surgeon, is the cornerstone of postoperative rehabilitation. Therapy protocols are carefully tailored to the specific procedure and may begin as early as the first postoperative day for tendon repairs requiring early motion. Therapy progresses through phases of protected motion, active motion, strengthening, and functional activities over a period of weeks to months. Patient compliance with the home exercise program prescribed by the hand therapist is critical to achieving the best possible outcome.
Follow-up appointments are scheduled at regular intervals to monitor healing, adjust splints, and advance the rehabilitation protocol. Sutures are typically removed at ten to fourteen days. Splinting may continue for six to eight weeks or longer depending on the procedure. Full functional recovery after complex hand surgery may take six to twelve months, and patients should be prepared for a gradual, progressive return to full hand use.

Expected Results
Outcomes of hand surgery vary widely depending on the specific condition treated, the severity of injury or disease, the timing of intervention, and the patient's compliance with postoperative rehabilitation. For traumatic injuries, earlier surgical repair generally produces better results. Primary tendon repair followed by structured hand therapy achieves good to excellent results in approximately 75 to 90 percent of cases [1]. Nerve repair outcomes depend on the patient's age, the level and type of nerve injury, and the time elapsed before repair, with younger patients and more distal injuries having the best prognosis for sensory and motor recovery.
Carpal tunnel release provides complete or near-complete relief of numbness and tingling in approximately 90 percent of patients, though recovery of sensation and strength may continue for several months after surgery [3]. Dupuytren fasciectomy achieves significant improvement in finger extension, though recurrence rates of 20 to 50 percent over five to ten years are well documented [1]. Digital replantation survival rates range from 70 to 90 percent at experienced centers, with functional outcomes improving over twelve to twenty-four months as nerve regeneration progresses [2].
Patients should understand that hand surgery recovery often requires extensive rehabilitation, and the final functional result depends heavily on the patient's active participation in hand therapy. Stiffness is the most common obstacle to optimal recovery, and early, consistent motion within the parameters set by the surgeon and hand therapist is essential. Complex injuries may require staged reconstruction over multiple procedures to achieve the best possible outcome, and patients should be prepared for a commitment that may extend over months or years.
Frequently Asked Questions
How long does it take to recover from hand surgery?
Recovery time varies significantly depending on the specific procedure. Simple procedures like carpal tunnel release may allow return to light activities within two to three weeks, while complex reconstructions involving tendon repair, nerve grafting, or microsurgical replantation may require six to twelve months for full recovery. Hand therapy is an essential part of recovery for most hand surgery patients, and the commitment to rehabilitation directly affects the quality of the final result. Your surgeon and hand therapist will provide a specific recovery timeline based on your procedure.

Can a severed finger be reattached?
In many cases, yes. Microsurgical replantation of severed digits is performed at specialized centers with high success rates, typically 70 to 90 percent for digit survival. The feasibility of replantation depends on the level and mechanism of injury, the condition of the severed part, and patient factors. If a finger is amputated, the severed part should be wrapped in moist gauze, placed in a sealed plastic bag, and kept on ice. The patient and amputated part should be transported to a replantation-capable center as quickly as possible.

What is the difference between carpal tunnel release and other hand surgeries?
Carpal tunnel release is a relatively straightforward procedure that involves dividing a ligament at the wrist to relieve pressure on the median nerve. It is one of the most commonly performed hand surgeries and has a high success rate with a relatively short recovery. Other hand surgeries, such as tendon repair, nerve grafting, fracture fixation, and Dupuytren fasciectomy, address different structures and conditions, vary widely in complexity, and have different recovery requirements. Your hand surgeon will recommend the appropriate procedure based on your specific diagnosis.
