Thumb pain
in Rockhampton
Thumb pain has a small number of common causes, and they sort themselves out by where exactly the pain is. The four anatomical locations below cover the great majority of presentations. Patients are seen at Mater Private Hospital Rockhampton from across Central Queensland.
What is going on
The thumb is the most loaded digit in the hand — most pinch, grip and pincer tasks pass through it — and it has a number of structures that can be the source of pain. The carpometacarpal joint at the base wears with time and with repetitive pinch loading. The first dorsal compartment tendons on the radial side of the wrist become inflamed with repetitive use. The ulnar collateral ligament at the metacarpophalangeal joint can tear in a forced abduction injury. And the scaphoid bone, just behind the anatomical snuffbox, can fracture in a fall on the outstretched hand.
Each of these structures has a characteristic location and a characteristic story, so localising the pain is the first step in the diagnosis. The four common patterns below run from most-to-least common in clinic — but the post-fall snuffbox presentation is the one that should be assessed urgently regardless of how mild the pain feels.
The four locations of thumb pain
Each card below pairs an anatomical location with the diagnosis it most commonly indicates. If the pain matches more than one pattern, the consult sorts out which structure is the primary driver.
- Base of the thumb
Where the thumb metacarpal meets the trapezium, on the radial side of the wrist crease.
Thumb CMC (basal joint) osteoarthritis
Wear of the cartilage at the carpometacarpal joint — by far the most common cause of chronic thumb pain in adults over 50, and more common in women. Pain is brought on by pinch grip — opening jars, turning keys, doing up buttons — and there is often a visible bump and grinding at the joint. Most settle with splinting and a corticosteroid injection; the minority that don't are candidates for trapeziectomy or Touch joint replacement.
- Radial side of the wrist
Just above the thumb, over the first dorsal compartment of the wrist — where the tendons that lift the thumb cross the radial styloid.
de Quervain's tenosynovitis
Inflammation of the tendon sheath of abductor pollicis longus and extensor pollicis brevis as they pass under the first dorsal compartment. Sharp pain when the thumb is stretched or used against resistance — lifting a baby, pouring a teapot, gripping a phone. Most often seen in new mothers and in people with repetitive thumb-loaded work. The Finkelstein and Eichhoff tests are positive at the bedside. Treatment escalates from splinting and corticosteroid injection through to surgical release of the first dorsal compartment.
- Anatomical snuffbox — after a fall
The hollow on the back of the wrist, between the thumb extensors, that becomes visible when the thumb is extended.
Scaphoid fracture Red flag
A fracture of the scaphoid bone is the classic missed wrist injury — the pain after a fall on the outstretched hand can be modest and the first X-ray can look normal, but the consequences of missing it are non-union and progressive wrist arthritis (SLAC wrist). Anatomical-snuffbox tenderness after a fall on the outstretched hand should be treated as a scaphoid fracture until proven otherwise: immobilisation in a scaphoid splint, repeat imaging at 10–14 days, MRI or CT if doubt remains. Confirmed scaphoid fractures are often best fixed with a single percutaneous screw to allow early movement and avoid the prolonged casting required for conservative management.
- Ulnar side of the thumb MCP
The webspace between the thumb and index finger, at the knuckle of the thumb.
Ulnar collateral ligament injury — skier's thumb / gamekeeper's thumb
Acute injury of the ulnar collateral ligament of the thumb MCP joint, classically from a fall onto an outstretched hand with the thumb forced into abduction — the ski-pole mechanism. Pain and bruising at the ulnar side of the thumb MCP, weakness of pinch grip and a sense of instability when opening a jar are characteristic. Complete tears with a Stener lesion need surgical repair; partial tears settle with thumb-spica splinting. Old, neglected tears (the classic gamekeeper's thumb) produce chronic instability and pinch weakness. Specialist assessment within a fortnight of injury is important — the repair is much harder once the ligament retracts.
Other causes to mention
A small number of thumb-pain presentations don't fit the four-location pattern above. These are less common as the lead complaint but worth knowing about — particularly because they have their own management pathways.
-
Trigger thumb
Catching, clicking or locking of the thumb in flexion — caused by thickening of the flexor tendon at the A1 pulley at the base of the palm. A tender nodule is usually palpable. Steroid injection settles most; persistent cases are released through a small palmar incision.
Trigger finger release → -
Carpal tunnel referral
Median nerve compression at the wrist often presents as numbness or tingling in the thumb, index and middle fingers, classically waking the patient at night. The pain is felt in the hand more than the thumb itself, but the thumb is one of the affected territories.
Carpal tunnel surgery → -
IP joint osteoarthritis
Wear of the interphalangeal joint of the thumb — much less common as the lead complaint than CMC arthritis, but seen in older patients with diffuse hand osteoarthritis. Splinting and injection are the mainstays; fusion is reserved for severe end-stage cases.
DIPJ arthritis →
The threshold for referral
Most thumb pain is initially managed in primary care — GP, splinting, anti-inflammatories and physiotherapy settle the majority. Specialist referral is appropriate when:
- The pain followed a fall and there is tenderness in the anatomical snuffbox — this should be triaged urgently for a possible scaphoid fracture.
- The pain followed a forced thumb abduction (a fall with a ski pole, a sport injury) — this should be triaged urgently for a possible UCL tear.
- Pain has not settled after 4–6 weeks of splinting and activity modification.
- A previous corticosteroid injection has worn off and the pain is back.
- There is a visible bump at the base of the thumb with pinch-grip pain — likely CMC arthritis on imaging.
- There is mechanical catching, clicking or locking of the thumb on flexion.
- Pinch grip is weak or the thumb feels unstable when applying force.
Acute injury — a fall on the outstretched hand, a forced thumb-abduction mechanism, a deep cut — is best seen early. The practice triages urgent referrals within a week.
How a thumb consult works
The first consult takes 30–40 minutes. It runs through a structured history (when, what made it worse, where exactly, what makes it better), a focused examination of the CMC joint, MCP joint, IP joint, first dorsal compartment, anatomical snuffbox, A1 pulley and median nerve, and a review of any imaging you bring. The consult ends with a diagnosis (or a clear plan to confirm it) and an itemised treatment plan — splinting, injection, further imaging, or surgery — written for the GP.
Hand therapy is coordinated on-site through Ruby Doolan's practice (Extend Rehabilitation), which keeps post-consult, post-injection and post-operative therapy in one place. The fees, Medicare rebates and quote process are on the fees page; GPs can find the referral pathway and urgency triage on the referrer page.

Patient questions we hear most
-
How do I know if my thumb pain needs surgery?
Most thumb pain doesn't need surgery. CMC arthritis often settles with a splint and a corticosteroid injection; de Quervain's commonly settles with the same combination; UCL partial tears settle in a thumb-spica splint. The conditions that more often need surgery are confirmed scaphoid fractures, complete UCL tears with a Stener lesion, and end-stage CMC arthritis that has not settled on non-operative management. The first job at consult is establishing the diagnosis — that determines the pathway.
-
I fell on my hand and my thumb is sore — do I need a scaphoid X-ray?
Yes. Any fall on the outstretched hand that produces pain in the anatomical snuffbox should be X-rayed. The first X-ray can look normal even when a scaphoid fracture is present, so if pain persists in the snuffbox after a fall the safest course is immobilisation in a scaphoid splint and repeat imaging at 10–14 days, or earlier MRI or CT if there is doubt. A missed scaphoid fracture is one of the more consequential missed injuries in upper-limb work — it can lead to non-union and progressive wrist arthritis.
-
Why does my thumb hurt at the base when I grip?
Pinch-grip pain at the base of the thumb is the classic presentation of CMC (carpometacarpal) joint osteoarthritis — wear of the saddle joint between the thumb metacarpal and the trapezium. Opening jars, turning keys, twisting taps, doing up buttons and writing all load this joint. The pain is usually accompanied by a visible bump at the base of the thumb and a feeling of grinding on movement. A plain X-ray confirms the diagnosis; treatment starts with a thumb-spica splint and a corticosteroid injection, with surgical options (trapeziectomy or Touch joint replacement) for the cases that don't settle.
-
Can de Quervain's go away on its own?
Often, yes. de Quervain's tenosynovitis is an inflammatory condition of the tendon sheath, and many cases settle with rest, activity modification (particularly when the trigger is a temporary load like lifting a newborn) and a thumb-spica splint. Cases that don't settle in 4–6 weeks of splinting typically do well with a single ultrasound-guided corticosteroid injection — the published response rate is high. The minority that recur after injection are candidates for surgical release, which is a small day-case procedure.
-
Should I see my GP first or come straight to a specialist?
GP referral is needed for a Medicare rebate, so the GP visit comes first regardless. The GP can also organise initial imaging (X-ray for any base-of-thumb pain or post-fall pain, ultrasound for suspected de Quervain's) which is useful at the first specialist consult. Acute trauma — a fall on the outstretched hand, a forced thumb-abduction injury, a deep cut — is best seen urgently and most GPs will refer the same week. Slow-onset pain that has not settled with simple measures and splinting is the typical referral pattern.
-
What imaging do I need before the consult?
Plain X-ray of the thumb and wrist is the baseline for any chronic thumb pain or any post-fall thumb pain — it shows CMC arthritis, IP arthritis, and most scaphoid fractures. Ultrasound is useful for soft-tissue conditions like de Quervain's and for guiding injections. MRI is reserved for cases where the X-ray is normal but the clinical suspicion of a scaphoid fracture or UCL tear is high. The consult uses whatever imaging exists; further imaging is arranged from the consult if needed.
