Carpal Tunnel Release (Endoscopic) Recovery
Endoscopic Carpal Tunnel Release
What the operation does
The carpal tunnel is a narrow passage at the base of the palm carrying the median nerve and nine tendons, roofed by a tough band of tissue. When the tunnel is too tight the nerve is squeezed. Here a camera is passed in through one or two small incisions at the wrist or palm, and the roof band is divided from underneath while the surgeon watches on a screen. The band is left open and heals with a gap.
What is actually different from the open operation
The band divided is the same, the nerve is freed the same way, and the long-term result is the same. What differs is the route in. Smaller incisions mean less soreness in the palm during the first weeks and, on average, a return to manual work about one to two weeks sooner. By around three months the two operations are hard to tell apart.
What improves first, and often immediately
Night symptoms. Most people find the waking with a numb, burning hand stops within days and many notice it the first night. That is the clearest early sign the operation has worked.
Pillar pain
Deep soreness in the heels of the palm, either side of the tunnel, when pressing on them or taking weight through the hand. It is generally less pronounced after the keyhole route than the open one, and it still occurs. It is not a sign anything went wrong, it typically settles over one to three months, and firm scar massage is what most helps it.
How much numbness recovers
Depends on how long and how badly the nerve was compressed, not on which operation was used. Intermittent tingling of recent onset usually resolves completely. Constant numbness present for years, particularly with wasting of the muscle at the base of the thumb, often improves only partly — surgery stops further damage more reliably than it reverses established damage.
Grip strength dips before it improves
Expected and temporary, and generally recovering a little quicker than after an open release. Grip is commonly weaker for around six to ten weeks before returning to at least its previous level.
When this route is not the right one
Worth knowing, because it is not simply the newer and better option. A direct view is preferred where the anatomy is unusual, where the nerve has been operated on before, where there is a mass or thickened lining to deal with, and where other work is being done at the same time. Choosing an open release in those situations is a judgement about safety, not a preference for the older technique.
Nerve injury
The recognised trade-off. Because the band is divided from underneath with the nerve close by, some series report a slightly higher rate of nerve irritation or injury than with an open release, though in experienced hands the difference is small. New or worsening numbness, or weakness in the thumb, after surgery is worth reporting promptly.
Move the hand from the start, and glide the nerve
Fingers, thumb, elbow and shoulder should all move normally from day one, and the hand should be used for light everyday tasks. A hand protected out of caution stiffens, and after an operation this small that is entirely avoidable. Alongside that, the median nerve has been sitting compressed and needs to move freely through its new space — gentle gliding encourages it to slide rather than tether in scar tissue, and it is among the most useful things in the early programme.
Wound care
One or two small incisions, kept dry until told otherwise — usually around ten to fourteen days. The wounds are small enough that the scar rarely becomes a long-term issue, which is one of the practical advantages of this route.
If symptoms do not improve
Where night symptoms persist unchanged after a few weeks, go back rather than wait. The commonest explanations are an incomplete release — slightly more likely with a keyhole approach than an open one — a nerve too damaged to recover, or symptoms coming from the neck. None improves with patience alone.
Whether it can come back
Uncommon. The divided band heals with a gap rather than reforming as it was, and true recurrence after a complete release is unusual. Returning symptoms more often reflect an incomplete release, scarring around the nerve, or another cause entirely.
Driving and work
Driving generally waits until you can grip and turn the wheel confidently without discomfort — commonly within a week. Desk-based work is often possible within a few days. Manual work involving gripping, pushing through the palm or vibrating tools commonly waits three to four weeks, typically a week or two sooner than after an open release.
How the first months usually unfold
The first week centres on the wounds, keeping the fingers moving and nerve gliding, with night symptoms usually already gone. One to four weeks brings normal use back and scar work begins. Four to ten weeks brings grip strength back and pillar soreness settling. Beyond three months, any remaining numbness continues improving slowly for up to a year.
Staying in touch with your care team
How long the nerve was compressed, and how severely, shape what recovers — and your surgeon knows what your nerve tests showed. If something about your recovery is worrying you or does not match what is described here — particularly new numbness or weakness after surgery — contact your care team rather than waiting.
