Understanding Wrist & Hand Pain —
Finding the Source

Ligament and tendon injuries produce overlapping symptoms — pain, swelling, reduced movement, and weakness — which is why self-diagnosis is unreliable. A key distinguishing feature is the mechanism of injury and the type of movement that reproduces pain. Ligament pain is typically provoked by stress applied across the joint (such as compression, distraction, or specific deviation), while tendon pain is reproduced by resisted active contraction of the muscle the tendon serves. Tenderness is also differentially located — over the joint line for ligament involvement, and over the tendon course for tendinopathies.

Clinical testing is required to make this distinction reliably. Finkelstein's test isolates the first dorsal compartment tendons; Watson's test stresses the scapholunate ligament; the TFCC load test targets the fibrocartilage complex. Imaging — ultrasound for tendons, MRI arthrography for ligaments — may be used to confirm findings, but always in the context of clinical examination rather than as a replacement for it.

The triangular fibrocartilage complex (TFCC) is a fibrocartilaginous disc and surrounding ligamentous structures that spans the ulnar side of the wrist between the ulna and the carpus. It performs two essential functions: it acts as the primary stabiliser of the distal radioulnar joint (DRUJ), and it provides a cushion that transmits load from the carpus to the ulna during forearm rotation and grip. When the TFCC is torn — either acutely or through degenerative wear — the result is ulnar-sided wrist pain, a mechanical clunk with forearm rotation, and reduced grip strength.

TFCC tears are classified by location and cause (Palmer Classification). Peripheral tears, which remain attached to the distal ulna, have better healing potential. Central degenerative tears are more common in older patients and less likely to heal spontaneously. MRI arthrography is the most accurate imaging investigation, but the clinical picture — ulnar fovea sign, DRUJ instability, load test — provides significant diagnostic information before any imaging is obtained.

Yes — cervical radiculopathy from C6 or C7 nerve root compression can produce pain, numbness, and weakness in the forearm and wrist that is clinically indistinguishable from a local wrist problem on first presentation. C6 radiculopathy affects the thumb and index finger — the same territory as carpal tunnel syndrome — which creates a common diagnostic confusion. C7 involvement produces middle finger symptoms and wrist extensor weakness. Both can present with wrist and forearm pain without any obvious neck pain.

ROOT METHOD routinely screens the cervical spine in all wrist and hand presentations, applying neurological testing and neural tension tests to determine whether the neck is contributing to the symptoms. Treating a wrist problem when the source is at C6 will produce no improvement — and the correct level must be identified before any local wrist treatment is initiated.

Wrist clicking has multiple causes — not all of which are clinically significant. A soft, painless click occurring consistently in the same position during movement may reflect normal tendon or joint mechanics without underlying pathology. However, a painful clunk — particularly on the ulnar side during forearm rotation — is a red flag for TFCC injury or carpal instability, particularly scapholunate ligament dysfunction. A dorsal click on wrist flexion and extension may indicate extensor carpi ulnaris (ECU) tendon subluxation.

The clinical significance depends on whether the click is painful, whether it is accompanied by weakness or instability, and what provokes it. A clunk that reproduces your wrist pain during clinical testing — such as the Watson's shift test or the TFCC grind test — is diagnostically important. Painless, consistent clicking in an otherwise normal wrist is generally benign. Any clicking that developed after an injury, that is worsening, or that is accompanied by instability warrants clinical assessment.

Most wrist and hand conditions respond to conservative management — targeted physiotherapy, splinting, activity modification, and occasionally injection — when the correct structural diagnosis has been made. Surgery is generally considered when conservative management has failed over an adequate time period, when there is a complete structural rupture that does not heal (such as a full-thickness TFCC peripheral tear or complete scapholunate ligament disruption), or when there is progressive instability causing secondary joint damage.

For carpal tunnel syndrome, night splinting and activity modification resolve mild cases; surgical decompression is highly effective when conservative measures fail and nerve conduction studies confirm significant compression. For ligament instability, early surgical intervention may be recommended to prevent the secondary carpal malalignment and arthritis that follows untreated instability. ROOT METHOD's assessment identifies which patients are likely to respond to conservative care and which require prompt surgical referral.

Splint selection depends entirely on the structural diagnosis. A wrist cock-up splint (maintaining the wrist in neutral extension) is appropriate for carpal tunnel syndrome — particularly worn at night to prevent prolonged wrist flexion during sleep. A thumb spica splint immobilising the wrist and thumb is the correct choice for De Quervain's tenosynovitis or scaphoid pathology. Ulnar-side TFCC-related instability may be managed with a DRUJ splint or brace that limits forearm rotation.

Wearing the wrong splint provides no benefit and may delay recovery by maintaining the wrist in a position that worsens the underlying problem. Generic wrist supports available over the counter are not a substitute for condition-specific bracing. ROOT METHOD provides specific splinting recommendations as part of the treatment protocol, based on the identified structural diagnosis.
