Scaphoid fractures are breaks in the scaphoid bone, one of the small carpal bones on the thumb side of the wrist. The scaphoid plays a key role in wrist stability and coordination by linking the two rows of carpal bones and supporting load transfer through the wrist and hand. It is uniquely shaped and has a limited blood supply, making it vulnerable to complications if injured. Scaphoid fractures are the most common type of carpal bone fracture and are particularly frequent in young, active adults.
These fractures most often occur after a fall onto an outstretched hand, with the wrist extended and the force directed through the base of the thumb. Unlike other wrist fractures, they can be difficult to detect early and are sometimes misdiagnosed as wrist sprains.
Symptoms may include pain on the thumb side of the wrist, swelling, and tenderness in the anatomical snuffbox – a small hollow area at the base of the thumb. Some people retain reasonable wrist movement, which can delay diagnosis. If left untreated or poorly managed, scaphoid fractures carry a risk of non-union due to the bone’s poor blood supply.
Treatment depends on the location and severity of the fracture. While many scaphoid fractures can be managed with casting, others – particularly those that are displaced or located closer the forearm – require surgery to stabilise the bone and promote healing.
Physiotherapy plays a crucial role in scaphoid fracture recovery. It helps restore wrist and thumb movement, rebuild grip and wrist strength, and support a safe return to sport, work, and daily tasks. A structured rehabilitation plan is essential to reduce the risk of stiffness, weakness, and long-term wrist dysfunction.
Key Facts
- Scaphoid fractures are the most common carpal fractures. 🔗
- In young people, scaphoid fractures account for about 50%–80% of all carpal bone fractures. 🔗
- Guidelines for acute scaphoid fractures recommend MRI or CT within 3–5 days when a scaphoid fracture is suspected but initial X-rays are negative. 🔗
Risk Factors
- Young, active people participating in skating, cycling, football codes, basketball, netball, or skiing (higher fall risk).
- Previous wrist injury or reduced protective reactions during falls.
- Delayed diagnosis or continuing sport/work on an undiagnosed fracture.
- Fractures closer to the proximal pole (higher risk of healing problems).
- Fracture displacement (bones not well aligned).
- Jobs requiring heavy manual handling, repetitive gripping, or vibration tools.
- Poor adherence to immobilisation instructions (removing splint/cast against advice).
Symptoms
- Pain and tenderness on the thumb side of the wrist, particularly in the anatomical snuffbox (a small hollow area near the base of the thumb)
- Swelling and bruising around the wrist
- Reduced grip strength
- Pain during thumb movement or when gripping objects
- Increased pain with wrist extension (bending the wrist backwards)
- Pain when pressing on the scaphoid tubercle on the palm side of the wrist
Aggravating Factors
- Strong gripping or pinching (tools, lifting weights, carrying shopping bags).
- Pushing up through the palm (getting out of a chair, push-ups, planks).
- Repeated wrist extension (cycling handlebars, gym presses, catching a ball).
- Twisting actions (opening jars, wringing a towel).
- Contact sport or falls risk activities before the fracture is confirmed healed.
- Removing the splint/cast too often or too early (if not advised by your treating team).
Causes
Most scaphoid fractures occur from a fall onto an outstretched hand with the wrist extended and slightly bent toward the thumb side. This position funnels force into the scaphoid. They can also happen from direct impact (for example, a hard tackle, punching injuries, or a fall from a skateboard or bike).
A key issue with scaphoid fractures is that the bone’s blood supply is less robust toward the proximal pole (the end closer to the forearm). If a fracture disrupts blood flow, healing can be slower or incomplete. That is why early diagnosis, appropriate immobilisation (or surgery in selected cases), and well-timed scaphoid fracture physiotherapy exercises matter. Physiotherapy for scaphoid fracture does not “force” the bone to heal, but it helps protect the fracture, prevent avoidable stiffness, and progressively reload the wrist once healing is confirmed.
How Is It Diagnosed?
Diagnosis starts with a careful history and physical examination. A clinician will ask about the mechanism (often a FOOSH) and check for typical tenderness points, especially the anatomical snuffbox and the scaphoid tubercle. They will also assess swelling, range of motion, grip, and whether other structures could be injured (for example, scapholunate ligament injury).
X-rays are usually the first step, but a normal early X-ray does not reliably rule out a scaphoid fracture. If clinical suspicion is high, the safest approach is to treat it like a fracture until proven otherwise. That often means temporary immobilisation in a thumb spica or wrist splint and arranging more definitive imaging. From a physiotherapy perspective, early referral matters because your physio can help you protect the wrist, keep your fingers moving, and manage pain while you wait for imaging confirmation.
Investigations & Imaging
- X-ray
- First-line test to look for a visible fracture line, displacement, and other wrist fractures. Early fractures can be occult (not visible) and a repeat x-ray may be required.
- CT scan
- Excellent for defining fracture location, displacement, and later assessing bone healing (union), particularly when decisions about returning to load or sport are being made.
- MRI
- Very sensitive for occult scaphoid fractures and can also show bone bruising and associated soft tissue injuries.
Grading / Classification
- Location: Distal pole
- Closer to the thumb. Often heals more reliably due to better blood supply and may require a shorter immobilisation period.
- Location: Waist
- Middle of the scaphoid and the most common site. Healing is usually good if non-displaced, but rehab still needs careful progression.
- Location: Proximal pole
- Closer to the forearm. Higher risk of delayed union, non-union, and avascular necrosis, and more often managed surgically.
- Displacement: Undisplaced
- The fracture fragments are well aligned with no meaningful step or gap on imaging. Often suitable for cast or splint immobilisation, with structured scaphoid fracture rehab once healing is confirmed.
- Displacement: Displaced
- The fracture fragments are not well aligned, showing a measurable gap, step, or angulation on imaging (often with features suggesting instability). More likely to need surgical fixation and closer monitoring, and scaphoid fracture physiotherapy is progressed more cautiously to protect healing.
Physiotherapy Management
Physiotherapy for scaphoid fractures focuses on restoring wrist and thumb movement, rebuilding grip and forearm strength, and returning you to work, sport, and day-to-day tasks with confidence. Scaphoid fracture rehab is guided by fracture location and stability, confirmed healing on imaging, and whether you were treated in a cast or required surgery.
Early physiotherapy aims to protect the scaphoid while reducing swelling and maintaining movement and strength in the fingers, thumb, elbow, and shoulder during immobilisation. This helps prevent unnecessary stiffness and loss of function, and sets you up for a smoother return to wrist loading once your treating team confirms it is safe.
Exercise
Scaphoid fracture physiotherapy exercises begin with gentle finger and thumb movements (as allowed), plus forearm rotation and elbow and shoulder exercises to prevent stiffness while the wrist is protected. If you are in a cast or rigid splint, your physio will prioritise what you can safely move without stressing the fracture site.
Wrist range-of-motion exercises are introduced once immobilisation is reduced or removed, or once your surgeon clears movement after fixation. Scaphoid fracture rehab typically starts with short, frequent sessions of controlled wrist flexion, extension, and side-to-side movement, plus progressive thumb control to restore pinch and grip function.
Strengthening exercises for the wrist, forearm, and grip are gradually progressed as healing allows, starting with light isometrics and moving into resistance work. This is followed by functional tasks such as lifting, carrying, twisting, and graded weight-bearing through the hand (for example, wall leans, bench supports, then floor-based loading), because scaphoid fractures are commonly aggravated by wrist extension under load.
Activity Modification
Activity modification includes avoiding heavy lifting, forceful gripping, twisting, and weight-bearing through the wrist early in recovery, especially positions that load the scaphoid such as wrist extension with pressure through the palm. Your physiotherapist will help you keep training and working safely by adjusting tasks, using the other hand more, and choosing wrist-friendly exercises while the scaphoid heals.
Activities are gradually reintroduced based on pain, movement, strength, and confirmed healing. In scaphoid fracture rehab, return to push-ups, bench press, planks, manual tools, and contact sport is usually staged, because returning too quickly can overload a healing scaphoid even when everyday pain seems improved.
Manual Therapy
Manual therapy may be used to address wrist, thumb, and forearm stiffness once fracture stability and healing allow. After scaphoid fractures, stiffness is often felt in wrist extension, forearm rotation, and thumb movement, particularly after weeks in a cast or after surgery.
A physiotherapist may use gentle joint mobilisation and soft tissue techniques to reduce protective muscle guarding and help you regain movement so your scaphoid fracture physiotherapy exercises feel easier and more effective. Manual therapy should support loading progressions, not replace them, and it should not create sharp pain or heavy compression through the scaphoid.
Heat & Ice
Ice can help manage pain and swelling early, particularly after exercises or after being more active than usual. Heat may assist with stiffness later in scaphoid fracture rehab, especially before range-of-motion work, so the wrist loosens up enough to move without excessive guarding.
Education
Education helps you understand scaphoid healing timelines, why some fractures need longer protection, and why imaging is often used to guide safe loading. Your physiotherapist will explain which symptoms are expected (stiffness, weakness, mild ache with new activity) versus warning signs that may suggest you are doing too much too soon.
Education also covers safe progression back to grip, twisting, lifting, and weight-bearing, plus how to pace activity so you rebuild wrist capacity without repeatedly flaring pain.
Other Treatments
Immobilisation in a cast or rigid splint is a mainstay treatment for many scaphoid fractures, especially those that are non-displaced. Follow-up appointments and repeat imaging help confirm that healing is progressing, which guides when scaphoid fracture physiotherapy exercises can safely progress.
Pain relief may include simple analgesics as advised by a pharmacist, GP, or treating specialist. In some delayed healing scenarios, specialist teams may consider bone stimulation strategies, but this is case-dependent. Regardless of the medical pathway, physiotherapy for scaphoid fracture remains valuable for maintaining function during immobilisation and for restoring wrist capacity afterward.
Surgery
Surgery is not needed for every scaphoid fracture, but it is commonly considered when the fracture is displaced, unstable, involves the proximal pole, or shows delayed union. The typical operation is internal fixation with a screw, sometimes with bone grafting if healing is delayed or a non-union is present. After surgery, a period of immobilisation is still common, followed by structured scaphoid fracture rehab.
Physiotherapy after scaphoid surgery focuses on protecting the repair while maintaining movement elsewhere in the arm, then progressively restoring wrist motion and strength once cleared. A physiotherapist also monitors red flags such as increasing pain, unusual swelling, significant loss of motion beyond expectations, or sensitivity changes, and communicates with the surgeon if progress stalls.
Prognosis & Return to Activity
The prognosis for scaphoid fractures is often good, particularly for undisplaced fractures that are diagnosed early and protected appropriately.
Bone healing commonly occurs over 6-8 weeks, however, depending on fracture location and stability, some people need longer immobilisation or surgical fixation. Even once the bone is healing, full recovery of wrist movement, grip strength, and confidence with pushing or weight-bearing through the hand can take several months. Consistent physiotherapy for scaphoid fracture is key to achieving the best outcome, as scaphoid fracture rehab helps restore wrist and thumb mobility, rebuild forearm and grip strength, and safely reintroduce functional tasks such as lifting, twisting, and graded weight-bearing needed for work, gym, and sport.
Complications
- Delayed union (slower healing than expected).
- Non-union (failure of the fracture to heal).
- Avascular necrosis or osteonecrosis (reduced blood supply to part of the scaphoid, more likely with proximal pole fractures).
- Persistent wrist stiffness after immobilisation or surgery.
Preventing Recurrence
- Reduce fall risk with balance training, safe footwear, and safer home/work surfaces to avoid falls onto an outstretched hand.
- Maintain wrist, thumb, and forearm strength after scaphoid fracture rehab, including ongoing grip and gradual weight-bearing tolerance.
- gradual weight-bearing tolerance. Optimise bone health through appropriate exercise and medical care if low bone density or osteoporosis is a factor.
When to See a Physio
- Immediately after a FOOSH with ongoing thumb-side wrist pain, even if initial X-rays are normal.
- If you have been placed in a cast or splint and want guidance on safe exercises for fingers, elbow, shoulder, and general training while immobilised.
- After cast removal or surgery, to start structured physiotherapy for scaphoid fracture and regain motion and strength safely.
- If you still cannot weight-bear through the hand, grip strongly, or return to sport/work tasks several weeks after immobilisation ends.
- If you feel unstable, “clunky”, or unusually painful with wrist movement during rehab.
- If swelling, stiffness, or sensitivity seems out of proportion, or progress plateaus.
