Surgery decisions · carpal tunnel
It isn't cut-or-suffer. See the three lanes side by side — with the real numbers and the five questions that decide which one is yours — before you see the hand surgeon.
Your input
The reframe
The catch most people miss: ‘wait and see’ is a real option, but it has a clock on it.
The three lanes, side by side
The same four rows across all three, so you can compare. These are what the research shows for people in general — not a prediction for you.
| Splint (± injection) first | Surgery (carpal tunnel release) | Watch and wait | |
|---|---|---|---|
| What it is | Night wrist splint; GP may add a steroid injection | Day procedure to release the ligament pressing the nerve | Change activities, review symptoms over time |
| What the research shows | Helps symptoms short-term; a good chunk improve, but the effect often fades and many later go on to other treatment (Cochrane splinting review; INSTINCTS trial, Lancet 2018) | The most reliable long-term fix — roughly 75–90% of people get good symptom relief (long-term outcomes review, PMC); lower long-term failure than injection (~12% vs ~42% at 6 yrs, JAMA-extension RCT, PMC) | Mild, intermittent symptoms can stay stable or even settle — especially if there's a reversible cause like pregnancy (healthdirect) |
| Best when | Mild–moderate, you want to avoid an op, or you need faster relief while deciding | Symptoms are constant, severe, or non-surgical options haven't held | Symptoms are mild and intermittent and not getting worse |
| The trade-off | Relief is often temporary; symptoms can return (Cochrane) | It's surgery: recovery time, scar tenderness, small risk of complications; recurrence ~5–10% (review, PMC) | Waiting too long with severe nerve compression can cause permanent thumb-muscle wasting and lasting numbness (healthdirect) |
These figures are general population research, not a prediction for you. The card doesn't decide your lane — that's the conversation with your GP, surfaced as the questions below.
The credibility check
No tool can tell you how bad your nerve is — that needs an exam and sometimes a nerve test. Two things the research is clear on, though: a splint's relief often fades, so ‘tried a splint’ isn't the same as ‘fixed it’ (Cochrane). And if you already have constant numbness or a weak, clumsy thumb, waiting is the riskiest lane — that's the point where nerve damage can become permanent (healthdirect). Surgery is the most reliable long-term fix, but it's still surgery. The right lane is a conversation with your GP, not a number off a website.

A clean one-page printout: the three lanes side by side, plus the five questions that decide which one is yours.
This is the general map. The full Carpal Tunnel decision kit walks your exact severity through each lane, with the recovery timeline and a question worksheet — and the risk-numbers tool turns ‘surgery works 80% of the time’ into what that means for 100 people like you.
