Wrist Pain After a Fall on an Outstretched Hand

You slipped, put your hand out to save yourself, and now your wrist hurts. Nothing looks out of place and your fingers still move, so it is tempting to call it a sprained wrist and wait. But the same fall can break the scaphoid or the end of the radius, or tear a ligament inside the wrist joint, and none of these need look dramatic in the first few days. Knowing which you are dealing with, and what to do if the first X-ray is clear, shapes how well your wrist recovers.

Key Takeaways

• A fall on an outstretched hand most often causes a scaphoid fracture, a wrist ligament sprain or a distal radius fracture.
• Pain in the hollow at the base of your thumb is a possible scaphoid fracture until proven otherwise.
• A normal X-ray in the first week does not rule out a scaphoid fracture. Persistent pain needs a recheck.
• After 50, the distal radius is the bone most likely to break.
• Most settle with splinting and guided rehabilitation; surgery is reserved for displaced, unstable or slow-healing injuries.

Why a Fall Injures the Wrist

When you land on your palm, often after slipping in wet or slippery conditions, the wrist is forced backwards and your body weight travels through a small area of bone and ligament. The wrist joint is made up of eight smaller carpal bones, including the scaphoid and lunate bones, plus the ends of the two forearm bones, and the ligaments that connect bones across it.

In younger adults with strong bone, the force tends to concentrate on the scaphoid, a small carpal bone on the thumb side. In people over 50, as bone density declines, the end of the radius is usually the weaker link and a broken bone is more likely. Ligaments can tear at any age, on their own or alongside a fracture, so these are among the most common injuries after a fall onto the hand.

At MTP Health, an orthopaedic and physiotherapy clinic on Sydney’s North Shore, we start by working out which of these patterns fits your fall and your symptoms.

Three Injuries to Consider

Scaphoid fracture

The scaphoid sits under the anatomical snuffbox, the small hollow at the base of the thumb. A fracture causes tenderness right there, mild swelling and no deformity. Many people keep reasonable movement, which is why these fractures are so often dismissed as sprains. The scaphoid also has a poor blood supply toward its upper end, so a missed fracture can fail to heal, which can lead to arthritis and chronic pain years later.

Wrist ligament sprain

Pain and swelling across the back or centre of the wrist, away from the thumb side, points toward a ligament injury. Most wrist sprains are partial and settle over a few weeks. The one to watch for is a tear of the scapholunate ligament, one of the fibrous tissues that link the scaphoid to its neighbour.

It can cause a clunk or weakness when you grip or push up from a chair. Left unrecognised, a completely torn ligament can let the carpal bones drift apart and wear the joint, causing ongoing pain. A tear of the triangular fibrocartilage complex on the little-finger side can give similar persistent wrist pain.

Distal radius fracture

A break of the end of the radius, often called a Colles fracture, is the most common wrist fracture in adults over 50. It usually announces itself with rapid swelling, bruising, sometimes a visible bend and an immediate reluctance to move your wrist. It is rarely missed on X-ray; the question is whether the bone has shifted or the joint surface is involved.

When the X-ray Looks Normal

Early X-rays miss a meaningful share of scaphoid fractures because the crack can be too fine to see, so early treatment is based on where it hurts as much as on the film. If your X-ray was clear but the snuffbox is still tender a week or two later, that is a reason to be reassessed, not reassurance.

Standard practice is to protect the wrist in a thumb splint, keep it raised to reduce swelling, and either repeat the X-ray at 10 to 14 days or arrange an MRI or CT scan, which can show what plain films cannot. An early review through our Urgent Injury Clinic is one way to get this sorted quickly. Lingering pain can also be the first sign of a scapholunate injury, which does not show on X-ray at all.

How the Injury Is Assessed

Assessment starts with how you fell and where it hurts most. Examination checks for tenderness at the snuffbox and scaphoid tubercle, swelling over the back of the wrist, ligament stability and a grip strength assessment compared with the other side, all part of reaching a proper diagnosis.

This kind of assessment is where these injuries are sorted from one another. Dr Mun Khin Chan, orthopaedic hand and wrist surgeon at MTP Health, reviews your examination and imaging with you. From the first visit, our physiotherapy team manages the splint, keeps your fingers, elbow and shoulder moving, and plans your rehabilitation.

Treatment Options for Each Injury

An undisplaced scaphoid fracture is usually treated with six to eight weeks in a cast or firm splint followed by graded rehabilitation. Fractures that are displaced, sit near the upper pole or fail to heal on a follow-up CT scan often need surgical intervention, fixed with a small screw. Surgery carries its own risks, including infection and stiffness, and Dr Chan weighs these against the risk of the fracture failing to heal on its own.

Mild sprains and other partial ligament injuries are managed with a short period of splinting and then progressive strengthening; most wrist sprains settle this way, though severe sprains take longer.

A complete scapholunate tear is different. Wrist arthroscopy allows the ligament to be inspected directly and, where appropriate, repaired or reconstructed, and this kind of tear can require surgical intervention or even surgery to prevent further damage.

For a distal radius fracture, a well aligned break is managed in a cast, while one that has shifted or extends into the joint may need a plate and screws. In every case the non-surgical option and simple home treatment are discussed first, and surgery is one step in a longer recovery.

Recovery and Getting Back to Normal

Bone typically takes six to eight weeks to unite, but wrist function takes longer. Once the cast or splint comes off, our physiotherapists and exercise physiology team guide you through restoring range of motion, grip strength and, finally, weight bearing through the palm. Gentle movement early helps prevent stiffness.

Return to contact sports, playing sport or heavy manual work and physical activity usually takes several months and depends on confirmed healing, not on how the wrist feels on a good day. People with health conditions that slow bone healing are at higher risk of a longer recovery.

Signs You Should Not Wait On

Seek medical attention promptly for wrist pain after an injury if the wrist looks bent, if the fingers are numb, tingling, pale or cold, or if swelling is worsening after 48 hours. In the meantime, an ice pack or cold pack wrapped in a towel can reduce pain and reduce swelling.

If the hand is cold or you have real trouble moving the fingers, see a doctor immediately, as this can signal a more serious injury. Just as important, if snuffbox pain is still present two weeks after a fall, or your grip stays weak and the wrist clunks with use, do not assume it is settling. When these symptoms persist, further treatment and a review with medical professionals give you the best chance of a full recovery.

Frequently Asked Questions (FAQs)

How do I know if my wrist is broken or sprained after a fall?

You often cannot tell from pain alone. Tenderness at the base of your thumb, obvious swelling or a change in shape point toward a fracture and need an X-ray. Pain lasting beyond a week warrants assessment even if the wrist moves well.

Can a scaphoid fracture be missed on an X-ray?

Yes. A proportion of scaphoid fractures are not visible on the first X-ray because the crack is too fine to see. If the snuffbox stays tender, the wrist is splinted and rechecked at 10 to 14 days, or an MRI or CT scan is arranged.

How long does wrist pain last after a fall?

A simple sprain usually improves within two to three weeks. Fractures need six to eight weeks to unite, then further rehabilitation. Pain that is not improving by two weeks should be reassessed rather than waited out.

Do I need surgery for a wrist injury from a fall?

Most people do not. Undisplaced scaphoid fractures, well aligned distal radius fractures and partial ligament sprains are usually managed in a cast or splint followed by physiotherapy. Surgery is considered when the bone has shifted, involves the joint or is slow to heal, or a major ligament has torn completely.

Should I see a physiotherapist or a surgeon first?

Either is reasonable, as long as the wrist is examined and imaged when indicated. At MTP Health the two work together, so if a fracture or ligament tear is suspected you can see Dr Chan and begin splint management and rehabilitation with the physiotherapy team in one place.

Conclusion

Wrist pain after a fall deserves attention, especially when it sits at the base of the thumb or refuses to settle. Sorting out early whether you have a scaphoid fracture, a ligament sprain or a distal radius fracture gives you a good chance of a straightforward recovery. If your wrist is still sore after a fall, book an assessment with MTP Health or call (02) 9437 9794.
