What does this surgery treat?
Damage to a peripheral nerve that carries signals between the arm, hand, and nervous system.
Surgery may be considered for a cut nerve, a gap in a nerve, or certain injuries that are not recovering.
Reconstructive Surgery • Hands and Wrists
Peripheral Nerve Repair / Reconstruction
Peripheral nerve repair or reconstruction reconnects or reroutes injured nerves to help restore feeling or movement in the hand and wrist.
Will feeling or strength return right away?
Usually not. Nerve recovery is slow and may be incomplete.
Changes can develop over months or longer, depending on the injury, distance to the target, and health of the muscles and sensory tissues.
Does every nerve injury need repair?
No. Some injuries recover with protection, therapy, and observation.
A prompt specialist assessment helps distinguish an injury that can be monitored from one where delaying surgery could limit recovery.
01 · Overview
Helping nerve signals reach the hand again
Peripheral nerves carry signals for sensation and muscle movement. A cut, crush, stretch, or other injury near the hand or wrist can cause numbness, weakness, pain, or loss of coordinated movement. The pattern depends on which nerve is affected and how severely it is damaged. [1]
Repair or reconstruction aims to give nerve fibers a pathway to their targets. A surgeon may join nerve ends directly, bridge a gap, or connect a functioning donor nerve to a damaged nerve pathway. The choice depends on the injury, available healthy tissue, and time since damage occurred. [2]
This is different from carpal tunnel release, which relieves pressure on a nerve, and tendon repair, which reconnects the tissues that move joints. These procedures may sometimes be combined, but they address different problems. An examination and, when useful, nerve testing help establish what needs treatment. [2]
- Main goal
- Improve nerve continuity or redirect working nerve signals
- Common approaches
- Direct repair, nerve graft, conduit, or nerve transfer
- Anesthesia
- Regional or general, depending on the operation
- Recovery
- Wound healing precedes nerve recovery, which can take months or longer
How does the surgeon assess an injured nerve?
The assessment includes the injury history, skin sensation, muscle strength, and hand movement. Nerve conduction studies, electromyography, or imaging may help clarify the location and severity. Tests may need to be repeated because their usefulness changes with time after injury.
Why does timing matter?
A cleanly cut nerve may need early repair, while some crush or stretch injuries need observation before a plan becomes clear. Muscles that remain without nerve signals can become harder to restore. A new injury with numbness or weakness deserves prompt medical assessment rather than waiting for a routine consultation.
02 · Concerns & Goals
Changes you may want to discuss
An injured nerve can affect how your hand feels, moves, and handles daily tasks. Your symptoms and priorities help guide the discussion.
Numbness or reduced protection
Reduced feeling can make it harder to detect heat, sharp objects, or pressure, even when the skin looks normal.
Weak grip or pinch
You may struggle with buttons, tools, opening containers, or holding objects securely.
Nerve pain or sensitivity
Burning, electric-shock sensations, or tenderness at an injury site may interfere with sleep and hand use.
Loss of coordinated movement
Changes in finger control or muscle balance can affect fine tasks and, over time, joint position.
03 · Options
How the approaches differ
Your surgeon will recommend an approach based on the injured nerve, the size of any gap, tissue quality, and the functions you most want to regain.
Direct nerve repair
Joins healthy nerve ends without excessive tension.
How it worksThe surgeon aligns and secures the nerve ends using microsurgical techniques.
May suitSelected injuries where the ends can meet safely after damaged tissue is removed.
Main tradeoffIt cannot bridge every gap, and reconnection does not guarantee that all nerve fibers reach the right targets.
Nerve graft reconstruction
Bridges a gap with nerve tissue.
How it worksA graft from another part of your body or processed donor nerve tissue connects the separated ends.
May suitSelected gaps that cannot be closed with a tension-free direct repair.
Main tradeoffA graft from your body creates another surgical site and an area of reduced sensation. Donor grafts are not appropriate for every nerve or gap.
Nerve conduit
Uses a small tube to guide growth across a selected gap.
How it worksThe nerve ends are placed within a conduit that provides a protected pathway.
May suitCertain short gaps, particularly in smaller sensory nerves.
Main tradeoffIts usefulness depends on gap length, nerve type, and the surrounding tissue; it is not interchangeable with a graft.
Nerve transfer
Redirects a functioning nerve branch toward a more important lost function.
How it worksA selected donor nerve or branch is connected to a nerve pathway closer to its target.
May suitSelected injuries where the original pathway is unlikely to recover adequately.
Main tradeoffThere may be a loss of donor function, and therapy is needed to learn how to use the new signal pathway.
The final plan may change if surgery reveals more damage than testing suggested. Ask which alternatives you are consenting to and how donor-site effects would be handled. [2].
Can scar tissue around a nerve be treated instead?
Sometimes. Neurolysis frees a nerve from surrounding scar, while decompression releases pressure. These may help an intact nerve in selected circumstances, but neither replaces a missing segment of nerve.
Is a tendon transfer the same as a nerve transfer?
No. A tendon transfer reroutes a working muscle's tendon to substitute for a lost movement. A nerve transfer redirects nerve signals. Tendon transfer may be discussed when nerve reconstruction is unlikely to restore useful movement or as part of a broader reconstruction.
04 · Results
What may improve and what may remain
Sensation
Protective feeling may improve without returning to normal.
- Touch recognition, temperature awareness, and fine discrimination may recover differently.
- Areas of numbness, tingling, or altered sensation may remain.
Movement and strength
Useful movement depends on nerve recovery and the condition of the muscles and joints.
- Injury severity, delay before treatment, and distance to the muscle affect the outlook.
- Hand therapy helps preserve motion and retrain function as recovery allows.
Pain and daily function
Pain may improve, persist, or occasionally worsen.
- Recovery is assessed through examinations and practical tasks, not wound appearance alone.
- Further therapy, pain care, or additional reconstruction may be needed.
A repaired nerve needs time to regrow and reconnect with its targets. Full recovery is not always possible, and your surgeon should explain the expected range for your particular injury. [2]
05 · Recovery
Planning your recovery
Recovery at a glance
- Stay after surgery
- Determined by Your Surgeon
- Initial recovery at home
- Varies by Individual
- Return to desk work
- Varies by Procedure and Work Activity
- Light daily activities
- Based on Individual Recovery
- Strenuous exercise
- Based on Surgeon Clearance
Returning to work does not mean fully healed. Follow your surgeon’s instructions; strenuous activity requires clearance.
Recovery has two overlapping parts: protecting the surgical repair and supporting longer-term nerve recovery. Your plan may differ if tendons, blood vessels, or bones were also injured.
Step 1 · Day of surgery
Treatment day
Your team explains dressing or splint care, pain management, and which movements are allowed. Whether you go home the same day depends on the operation and your health.
Step 2 · Early days and weeks
Protecting the repair
Follow-up focuses on the wound, swelling, circulation, and protection of the reconstruction. Your team sets the position and duration of any splint and the limits on hand use.
Step 3 · As cleared by your team
Guided rehabilitation
A hand therapist may guide motion, scar care, sensory retraining, and later strengthening. Exercises must match the repair and any other injured structures.
Step 4 · Months and sometimes longer
Tracking nerve recovery
Repeat assessments track changes in sensation and muscle function. Returning to work or having a healed incision does not mean the nerve has finished recovering.
Planning everyday activities
ActivityGeneral planning contextWhat affects the plan
Desk workPlanning context: Depends on discomfort, hand dominance, splinting, and the ability to protect the repair.What affects it: Typing and repetitive hand use may need limits or accommodations.
DrivingPlanning context: Requires safe control of the vehicle and clearance from your team.What affects it: A splint, weakness, numbness, or sedating medication can make driving unsafe.
Lifting and manual workPlanning context: Often restricted longer than light daily activities.What affects it: Forceful gripping, pulling, and vibration may stress the repair or injure a numb hand.
Exercise and sportsPlanning context: Return is staged according to wound healing, repair protection, and hand control.What affects it: Activities with falls, impact, or weight through the hand may require a longer pause.
Ask for written restrictions tailored to your job, hobbies, and reconstruction. Follow your surgical team's instructions rather than a general recovery calendar.
Before your procedure
- Bring injury records, prior operation notes, and any nerve tests or imaging.
- List medications, supplements, allergies, and medical conditions; ask which medicines need adjustment.
- Discuss nicotine use and a cessation plan because nicotine can interfere with healing.
- Arrange transportation and help with tasks that require both hands.
- Ask about splinting, hand therapy access, and likely work accommodations.
- Confirm fasting instructions and whom to contact if symptoms change before surgery.
How do I protect a hand with reduced feeling?
Ask your team how to check the skin and avoid burns, cuts, and prolonged pressure. Do not rely on a numb hand to judge temperature. Protection remains important even after the incision heals.
Does tingling mean the nerve is healing?
Tingling can occur during nerve recovery, but it can also reflect irritation or ongoing injury. It does not prove that recovery is progressing. Report changes and let your team interpret them alongside strength and sensation testing.
06 · Safety
Risks and what your clinician assesses
Temporary soreness, swelling, bruising, and incision sensitivity may occur. Numbness and weakness often remain while the nerve recovers; worsening symptoms should be assessed rather than assumed to be normal.
Incomplete or absent recovery
Feeling or movement may not return as hoped, even when the repair heals.
Persistent or increased nerve pain
Painful scarring or a neuroma, a sensitive growth at an injured nerve end, may develop. Complex regional pain syndrome can also occur.
New sensory or movement changes
Nearby nerves may be injured, and nerve graft harvest or nerve transfer can cause donor-area numbness or weakness.
Infection or wound problems
Infection, delayed healing, or wound separation may require medication or another procedure.
Bleeding, scarring, or stiffness
A blood collection, scar tethering, or joint stiffness can affect healing and hand function.
Anesthesia and general surgical complications
Anesthesia reactions and blood clots are possible. Your health and the extent of surgery influence these risks.
Discuss these risks and your individual health history with your surgeon. [3]
What your clinician assesses
- Which nerve is injured, how severely, and whether any recovery is already occurring
- Time since injury, gap length, and the condition of nearby skin, tendons, vessels, and bones
- Diabetes, circulation, nicotine exposure, and other factors that affect healing
- Your functional priorities, donor-nerve options, and ability to participate in rehabilitation

08 · Questions
Common questions
Can an old nerve injury still be treated?
Sometimes. The options depend on the time since injury, remaining muscle function, and tissue condition. Nerve reconstruction, tendon transfer, or other approaches may be considered, but an examination is needed to assess what remains achievable.
Will I need hand therapy?
Hand therapy is often an important part of care. The timing and exercises depend on your reconstruction, and unsupervised stretching or strengthening could place stress on a healing repair.
Will there be a scar somewhere other than my hand?
There may be if your surgeon takes a nerve graft from another part of your body. Ask where the graft would come from and what lasting numbness or other donor-site effects to expect.
Can surgery guarantee normal hand use?
No. Improvement may be partial, and some numbness, weakness, or pain may remain. Your surgeon can discuss realistic goals and backup options based on your injury.
