How do I know if it is a sprain or a broken bone?

You often cannot tell from the outside — a scaphoid fracture can feel much like a sprain. Warning signs include tenderness in the snuffbox on the thumb side, severe swelling or deformity, and an inability to move the wrist. Because a scaphoid fracture can be missed, any fall with thumb-side wrist pain should be X-rayed.

What is the anatomical snuffbox and why does it matter?

It is the small hollow at the base of the thumb, most visible when you stretch the thumb out. Tenderness there after a fall on an outstretched hand strongly suggests a possible scaphoid fracture and needs an X-ray, sometimes a repeat scan later even if the first is normal.

My X-ray was normal but it still hurts — should I worry?

Possibly, yes. Scaphoid fractures often do not show up on the first X-ray, so if snuffbox pain persists after about a week, you should return for a repeat X-ray or an MRI or CT. Continuing to treat a hidden fracture as a sprain risks it not healing.

Can I just treat a wrist sprain at home?

A confirmed mild sprain can usually be managed with protection, rest, ice, compression and elevation and simple pain relief for the first couple of days. But get it checked first if there was a significant fall, thumb-side tenderness, marked swelling, deformity or numbness, to be sure it is not a fracture.

How long does a wrist sprain take to heal?

Many mild sprains feel much better within about two weeks, while more severe ligament tears take longer and may need hand therapy. If it is not improving on schedule, see a doctor to reconsider the diagnosis, including a possible missed fracture.

Wrist Sprain in Singapore: Sprain or Scaphoid Fracture?

Written & reviewed by the BestDoctors.sg editorial team · Last updated 24 Aug 2026 · General information, not medical advice

A wrist sprain is a stretch or tear of one or more of the wrist’s ligaments, most often from a fall onto an outstretched hand or a sudden twist. It ranges from mild overstretching to a complete ligament tear. The single most important point is that the same fall can also fracture a bone — especially the scaphoid on the thumb side of the wrist — and a scaphoid fracture is easily mistaken for “just a sprain,” so a fracture must be excluded first.

Tenderness in the “anatomical snuffbox” on the thumb side after a fall on an outstretched hand needs an X-ray to look for a scaphoid fracture — and a repeat X-ray or scan if it still hurts after a week, even if the first X-ray looked normal.

How it happens

The typical mechanism is a fall onto an outstretched hand, a sudden twist, or forced bending of the wrist. Severity ranges from mild overstretching (Grade 1), to partial tearing (Grade 2), to a complete ligament tear (Grade 3). Because the wrist takes the force of a fall, the same event that sprains a ligament can crack a carpal bone, which is why assessment focuses on ruling out a fracture.

Common causes

Falls onto an outstretched hand are the leading cause, common in skating, basketball, netball, football, gymnastics and cycling, as well as everyday slips and trips. Activities that suddenly load or twist the wrist, and reduced bone strength or a previous wrist injury, all add to the risk.

Symptoms

There is pain, swelling and tenderness around the wrist, worse with movement or gripping, along with bruising, warmth and a feeling of weakness or instability, and reduced range of motion. A more severe sprain may involve a “pop” or tearing sensation at the time of injury. A crucial warning pattern is pain and tenderness on the thumb side of the wrist, particularly in the anatomical snuffbox — the small hollow at the base of the thumb — which can point to a scaphoid injury even when the pain seems deceptively mild.

Red flags — exclude a fracture first

Snuffbox tenderness after a fall on an outstretched hand needs an X-ray to look for a scaphoid fracture. An inability to move or use the wrist, an inability to grip or bear weight, significant swelling or an obviously bent or crooked wrist, severe pain, or numbness, tingling or weakness in the hand all warrant assessment, and cold, pale or blue fingers or an open wound with visible bone need emergency care — a severe deformity, uncontrolled bleeding or a cold, pulseless hand is a 995 call. The critical safety message is that a scaphoid fracture is frequently not visible on the first X-ray, and the scaphoid has a delicate blood supply, so a missed fracture can fail to heal or lead to bone death and later arthritis. For that reason, snuffbox tenderness is treated as a possible scaphoid fracture until proven otherwise: the wrist is immobilised and re-imaged after a week or two, or a specialist review is arranged, rather than dismissing it as a sprain.

How it is assessed and treated

Assessment covers how the injury happened, where it is tender, swelling, range of motion and grip, and nerve and circulation checks, with clinicians specifically pressing the snuffbox and scaphoid. An X-ray is the key first investigation after a significant injury or any fracture suspicion, with repeat imaging — a further X-ray after ten to fourteen days, or an earlier MRI or CT — if a scaphoid fracture is suspected but the first X-ray is normal. A GP, emergency doctor or sports physician handles initial assessment and fracture exclusion, a hand therapist leads rehabilitation, and a hand surgeon manages confirmed fractures or complete ligament tears. For a confirmed mild-to-moderate sprain, early self-care uses protection with a wrist support, rest, ice, compression and elevation, plus simple pain relief, followed by graded hand-therapy exercises once a fracture is excluded and acute pain settles. A suspected or confirmed scaphoid injury is usually immobilised in a cast pending imaging or healing, and surgery is reserved for displaced fractures, complete ligament tears, or injuries not settling.

Recovery and getting back to activity

Most simple sprains improve within about two weeks, while more severe ligament injuries take longer and benefit from hand therapy to restore grip and prevent stiffness. Return to sport or heavy use is gradual, guided by comfort and strength, and a wrist support can help during the early return to activity. The key safeguard through recovery is not to assume the problem was “only a sprain”: if pain, swelling or weakness has not improved after a week or two, or the thumb-side of the wrist stays tender, go back for reassessment and, if needed, repeat imaging, because a hidden scaphoid fracture treated as a sprain can quietly fail to heal.

When to see a doctor

See a doctor after any fall on an outstretched hand with thumb-side (snuffbox) tenderness, for an inability to use the wrist, significant swelling or deformity, numbness or severe pain, or for pain, swelling or weakness that has not improved after a week or two.
