Educational summary only.
Red flags
- Deformity or inability to move after traumaA visible deformity or an inability to move the wrist or fingers following a fall or direct injury raises concern for fracture and warrants urgent evaluation.
- Progressive weakness or muscle wastingWorsening weakness or visible loss of muscle bulk at the base of the thumb can indicate significant, longstanding nerve compression.
- Signs of infectionIncreasing redness, warmth, and swelling, particularly with fever, raise concern for infection in the hand and require prompt medical attention.
- Sudden, complete loss of sensationA sudden and complete loss of sensation in the hand, especially after trauma, should be evaluated urgently to rule out significant nerve or vascular injury.
When to stop
- Increasing numbness or tinglingNumbness or tingling that spreads or intensifies during activity suggests the task may be aggravating nerve compression and warrants reassessment.
- New weakness in grip or pinchA new or worsening inability to grip or pinch with normal strength should prompt a pause in activity and clinical evaluation.
- Sharp pain during tendon-loading exerciseA sudden, sharp pain during a loading exercise, rather than the mild discomfort sometimes expected, is a signal to reduce load or reassess technique.
- Persistent swelling or warmthSwelling or warmth that does not settle with rest and elevation should be evaluated by a clinician.
Return checkpoints
- Resolved or stable nerve symptomsNumbness or tingling should have resolved or stabilized, with no ongoing progression, before returning to demanding repetitive tasks.
- Grip and pinch strength near baselineStrength testing should approach pre-injury levels or match the uninvolved hand before full return to heavy use.
- Pain-free tendon-specific movementMovements that previously provoked pain, such as thumb extension in De Quervain's tenosynovitis, should be tolerated without significant discomfort.
- Addressed contributing ergonomic factorsWhere relevant, workstation setup or repetitive task technique linked to the original problem should be addressed to reduce recurrence risk.
