📋 Key Information Summary
- Arm and hand pain is a common presenting complaint in Australian general practice, accounting for a significant proportion of musculoskeletal consultations.
- Use a systematic diagnostic model — localise pain by compartment (lateral, medial, anterior, posterior), assess for neurological compromise, and identify red-flag features (night pain, progressive weakness, systemic symptoms).
- Tennis elbow (lateral epicondylar tendinopathy) is the most common cause of lateral elbow pain; diagnosis is clinical with pain on resisted wrist extension and tenderness over the lateral epicondyle.
- Medial epicondylar tendinopathy ("golfer's elbow") presents with medial elbow pain worsened by resisted wrist flexion and pronation; less common than lateral epicondylitis but follows the same evidence-based management principles.
- First-line management for epicondylar tendinopathy is progressive eccentric loading exercises, activity modification, and short-term analgesia; corticosteroid injections may provide short-term relief but are associated with higher recurrence rates.
- Carpal tunnel syndrome (CTS) is the most common peripheral entrapment neuropathy; diagnosis is clinical with nocturnal paraesthesia, thenar weakness, and positive Phalen's/Tinel's tests.
- Nerve conduction studies (NCS) are recommended for CTS when diagnosis is uncertain or surgery is being considered; available in major Australian centres (MBS item 11014).
- Conservative CTS management includes wrist splints (especially nocturnal), ergonomic modification, and corticosteroid injection; surgical decompression (carpal tunnel release) is indicated for refractory or severe cases with thenar atrophy.
- Pulled elbow (radial head subluxation) is a common paediatric injury typically in children aged 1–4 years, caused by longitudinal traction on the forearm with the arm extended.
- Pulled elbow reduction is achieved by supination–flexion or hyperpronation technique in the clinic or ED; success rates exceed 80% with the first attempt and the child should use the arm within 10–15 minutes.
- Always exclude non-accidental injury (NAI) in young children presenting with arm pain, particularly if the mechanism of injury is inconsistent or there are other injuries.
- Red flags requiring urgent imaging or referral include open fractures, neurovascular compromise, suspected septic arthritis, compartment syndrome, and progressive intrinsic hand muscle wasting.
Introduction & Australian Epidemiology
Pain in the arm and hand is one of the most common musculoskeletal presentations in Australian primary care. The upper limb is a complex structure comprising the shoulder girdle, arm (brachium), elbow, forearm, wrist, and hand — each anatomical region susceptible to distinct patterns of injury, overuse, entrapment neuropathy, and inflammatory disease. Effective diagnosis requires a structured regional approach that combines history, targeted examination, and selective investigation.
In Australia, musculoskeletal conditions affect approximately 7.3 million people and are the leading cause of disability (AIHW, 2024). Upper limb disorders account for roughly one-quarter of all musculoskeletal consultations in general practice (Britt et al., 2023). Lateral epicondylar tendinopathy has an annual incidence of 1–3% in the general population, with peak prevalence in adults aged 35–54 years. Carpal tunnel syndrome affects an estimated 3–6% of Australian adults and is the most common entrapment neuropathy worldwide. Pulled elbow (radial head subluxation) is one of the most frequent upper limb injuries in young children presenting to paediatric emergency departments.
This article provides an evidence-based diagnostic and management framework for the most clinically important causes of arm and hand pain encountered in Australian general practice, emergency medicine, and paediatrics.
Arm & Hand Diagnostic Model
A systematic approach to arm and hand pain involves localising the site of pathology, determining the mechanism (acute traumatic, overuse/ repetitive strain, insidious onset), identifying red flags, and correlating findings with the relevant anatomical structures. The following compartmental model helps clinicians narrow the differential diagnosis efficiently.
| Compartment / Region | Common Diagnoses | Key Clinical Features |
|---|---|---|
| Lateral elbow | Lateral epicondylar tendinopathy (tennis elbow), radial tunnel syndrome, osteochondritis dissecans | Pain over lateral epicondyle, aggravated by gripping and wrist extension; point tenderness over ECRB origin |
| Medial elbow | Medial epicondylar tendinopathy (golfer's elbow), cubital tunnel syndrome, UCL sprain (throwing athletes) | Medial elbow pain, worse with wrist flexion/pronation; ulnar nerve paraesthesia in ring and little fingers suggests cubital tunnel |
| Posterior elbow | Olecranon bursitis, triceps tendinopathy, olecranon stress fracture, posterior impingement | Swelling over olecranon (bursitis), pain with resisted extension (triceps tendinopathy) |
| Anterior forearm | Flexor-pronator tendinopathy, acute compartment syndrome, median nerve entrapment (proximal) | Forearm pain with gripping; tense forearm compartment in compartment syndrome |
| Wrist — volar | Carpal tunnel syndrome, Guyon's canal syndrome, flexor tenosynovitis (trigger finger) | Nocturnal paraesthesia in median nerve distribution (CTS); ulnar nerve symptoms (Guyon's) |
| Wrist — dorsal | De Quervain's tenosynovitis, dorsal wrist ganglion, scaphoid fracture, intersection syndrome | Finkelstein's test positive (De Quervain's); anatomical snuffbox tenderness (scaphoid) |
| Hand — fingers | Mallet finger, Boutonnière deformity, Dupuytren's contracture, PIP/DIP osteoarthritis, flexor tendon injury | Loss of active extension at DIP (mallet), inability to extend at PIP with hyperextension at DIP (Boutonnière) |
| Paediatric arm | Pulled elbow (radial head subluxation), supracondylar fracture, distal radius fracture (buckle/ greenstick) | Refusal to use arm after traction injury (pulled elbow); swelling and deformity after fall (fracture) |
Stepwise Diagnostic Approach
Tennis Elbow (Lateral) & Medial Epicondylar Tendinopathy
Lateral Epicondylar Tendinopathy (Tennis Elbow)
Lateral epicondylar tendinopathy is a degenerative tendinopathy of the common extensor tendon origin, predominantly involving the extensor carpi radialis brevis (ECRB). Despite its colloquial name, it is more commonly associated with occupational activities (repetitive wrist extension, gripping, tool use) than sporting activity. Peak incidence is between 35 and 54 years, with equal sex distribution.
Clinical Features
- Insidious onset of pain over the lateral epicondyle, radiating into the proximal forearm extensor mass.
- Aggravated by gripping (shaking hands, turning door handles, lifting a cup) and resisted wrist extension.
- Point tenderness directly over or just distal to the lateral epicondyle.
- Cozen's test (resisted wrist extension with elbow extended) and Mills' test (passive wrist flexion with elbow extended) are provocative.
- Grip strength is often reduced compared with the unaffected side.
Medial Epicondylar Tendinopathy (Golfer's Elbow)
Medial epicondylar tendinopathy involves the common flexor–pronator tendon origin, predominantly the flexor carpi radialis and pronator teres. It is less common than lateral epicondylitis (5–10:1 ratio) and is associated with repetitive wrist flexion and forearm pronation (golf, throwing sports, racquet sports, manual labour).
- Pain over the medial epicondyle, worsened by resisted wrist flexion and pronation.
- Point tenderness over the medial epicondyle; may be associated with ulnar nerve irritation (check for Tinel's sign at the cubital tunnel and paraesthesia in the ulnar nerve distribution).
- Differential diagnosis: Cubital tunnel syndrome, UCL injury (especially in throwing athletes), cervical radiculopathy (C7–C8).
Investigations
Management
Conservative (First-line — 80–90% resolve within 12 months)
Corticosteroid Injection
Corticosteroid injection (e.g., triamcinolone acetonide 20 mg or methylprednisolone acetate 20–40 mg with 1–2 mL 1% lignocaine) may provide short-term pain relief (4–8 weeks) but is associated with higher recurrence rates and worse long-term outcomes compared with physiotherapy alone at 12 months (Coombes et al., 2013). Consider injection only when:
- Symptoms are severe and impacting work/function despite 4–6 weeks of conservative management.
- Patient has declined or cannot access physiotherapy.
- Maximum of two injections per episode, separated by at least 6 weeks.
Referral & Surgical Options
Refer to an orthopaedic surgeon or sports medicine physician if symptoms persist beyond 6–12 months despite optimal conservative management. Surgical options include open or arthroscopic extensor tendon release (lateral epicondylar debridement) or ECRB release. Success rates for surgery range from 70–90% but recovery takes 3–6 months.
Carpal Tunnel Syndrome
Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy, caused by compression of the median nerve at the wrist within the carpal tunnel. It has a prevalence of 3–6% in the Australian adult population, with a peak incidence in women aged 45–64 years. Risk factors include female sex, obesity, pregnancy, diabetes mellitus, hypothyroidism, rheumatoid arthritis, repetitive wrist flexion activities, and genetic predisposition.
Pathophysiology
The carpal tunnel is a rigid fibro-osseous space bounded by the carpal bones dorsally and the transverse carpal ligament (flexor retinaculum) volarly. The median nerve and nine flexor tendons traverse this space. Any condition that increases the contents (e.g., tenosynovitis, oedema, space-occupying lesions) or decreases the volume (e.g., wrist fractures with displacement, osteophytes) will elevate pressure and compress the median nerve. Chronic compression leads to demyelination and, if prolonged, axonal degeneration.
Clinical Features
- Symptoms: Nocturnal paraesthesia and numbness in the median nerve distribution (thumb, index, middle, and radial half of ring finger). Patients often describe waking with a "dead hand" and shaking it to relieve symptoms (flick sign).
- Aggravating factors: Prolonged wrist flexion (driving, holding a phone, reading), repetitive gripping.
- Advanced features: Thenar muscle wasting (abductor pollicis brevis), weakness of thumb opposition, loss of two-point discrimination.
- Provocation tests: Phalen's test (wrist flexion for 60 seconds reproduces symptoms), Tinel's test (percussion over the carpal tunnel), carpal compression test (direct pressure over the carpal tunnel for 30 seconds).
Severity Grading
Investigations
Management
Conservative (First-line for mild to moderate CTS)
Surgical Management
Carpal tunnel release (open or endoscopic) is indicated for:
- Severe CTS with thenar atrophy or significant motor deficit.
- Moderate CTS that has failed 12 weeks of conservative management.
- Patient preference when the diagnosis is confirmed by NCS.
Surgery involves division of the transverse carpal ligament (flexor retinaculum) to decompress the median nerve. Success rates are 85–95%. Endoscopic release may offer faster functional recovery. Complications (uncommon) include pillar pain, incomplete release, nerve injury, and complex regional pain syndrome.
Pulled Elbow in Children
Pulled elbow (radial head subluxation, "nursemaid's elbow") is the most common upper limb injury in children under 5 years of age. It typically occurs in children aged 1–4 years and is caused by sudden longitudinal traction on the extended arm — for example, when a child is lifted or swung by the hand or wrist, or when a child suddenly jerks away while being held by the hand.
Pathophysiology
In young children, the radial head is smaller in diameter than the radial neck, and the annular ligament is relatively lax. Sudden traction on the forearm with the arm extended and the forearm pronated allows the annular ligament to slip over the radial head and become trapped in the radiohumeral joint. As the child grows (typically by age 5), the radial head enlarges and the annular ligament strengthens, making subluxation increasingly unlikely.
Clinical Features
- History: Sudden pull on the arm; the child immediately cries and refuses to use the affected arm.
- Examination: The arm is held in slight flexion and pronation at the side. The child resists all attempts at supination and elbow extension. There is no swelling, deformity, or localised tenderness.
- Key point: If there is swelling, ecchymosis, deformity, or point tenderness, suspect a fracture (particularly supracondylar or distal radius fracture) rather than pulled elbow.
Investigations
Reduction Techniques
Pulled elbow can be reduced in the clinic, emergency department, or urgent care setting without sedation or imaging. Two techniques have comparable success rates (80–95% on first attempt):
Stabilise the elbow with one hand. With the other hand, firmly supinate the forearm while applying gentle pressure over the radial head, then flex the elbow fully. A palpable or audible "click" is often felt.
Stabilise the elbow with one hand. With the other hand, firmly pronate the forearm (forced pronation) while applying gentle pressure over the radial head. This technique may have a slightly higher first-attempt success rate (range 90–97%).
Parent Education
- Explain the mechanism and reassure that this is a common, benign injury.
- Advise against lifting or swinging children by the hands or wrists.
- Recurrence occurs in approximately 20–40% of cases; advise parents to seek early reduction if it recurs.
- If recurrent episodes occur, consider orthopaedic or paediatric referral for assessment and potential casting to allow ligamentous tightening (rarely required).
