Carpal Hyperextension Rehabilitation

Overview

Carpal hyperextension occurs when the palmar support system fails, affecting ligaments, fibrocartilage, and flexor structures. Successful rehabilitation depends on identifying instability severity, protecting healing tissues, and rebuilding dynamic muscular support.

Key Clinical Points

• Accurate grading drives decision-making

  • Stress radiographs remain the diagnostic cornerstone for identifying instability.

  • Musculoskeletal ultrasound may help characterize palmar ligament, fibrocartilage, and tendon involvement.

• Stability determines treatment pathway

  • Some injuries may respond to OTC or custom orthotic support combined with rehabilitation.

  • Complete disruption of palmar support structures has limited healing capacity with conservative care alone.

• Dynamic support matters

  • Carpal and digital flexor strength contribute to functional stabilization.

“Successful outcomes depend on matching tissue healing, stability needs, and exercise progression to each patient’s presentation.”

Rehabilitation Priorities

• Protect injured palmar structures while maintaining safe limb use.

• Restore controlled terminal stance stability.

• Improve neuromuscular activation and dynamic muscular support.

• Address secondary compensations throughout the kinetic chain.

• Use functional assessment and tissue tolerance to guide progression.

Evidence Snapshot

• Imaging improves diagnosis and injury classification.

• Orthotic management may support selected ligament injuries.

• Progressive loading supports long-term functional recovery.

Clinical Pearls

• Evaluate the whole patient, not only the carpus; compensatory changes may occur in adjacent joints and the spine.

• Orthotic success depends on fit, skin tolerance, owner compliance, and integration with rehabilitation.

• Terminal stance control is a key functional indicator during recovery.
