Four Corner Fusion: Postoperative Rehabilitation Protocol
Phase I: Protection and Early Recovery (0–2 Weeks)
Immobilisation:
Long-forearm splint
Elevation encouraged to reduce oedema
Precautions:
Avoid lifting, gripping, and weight-bearing through the wrist
Protect the fusion site and soft tissues
Avoid forceful finger or forearm loading
Therapy:
Finger and thumb range of motion exercises
Elbow and shoulder mobilisation
Oedema control and wound care
Tendon gliding exercises
Maintain mobility of uninvolved joints
Criteria to Progress:
Healing wound
Controlled pain and oedema
Good finger mobility
Phase II: Continued Protection and Progressive Motion (2–6 Weeks)
Immobilisation:
Transition to fiberglass below-elbow cast at approximately 2 weeks
Continue immobilisation until 6 weeks postoperatively
Precautions:
Avoid lifting, gripping, or weight-bearing through the wrist
Avoid forceful wrist motion
Avoid impact loading
Therapy:
Continue finger and thumb range of motion
Continue elbow and shoulder mobilisation
Oedema management
Maintain tendon mobility
Criteria to Progress:
Minimal pain and swelling
Radiographic progression of fusion
Good digital motion
Phase III: Progressive Motion and Early Strengthening (6–12 Weeks)
Immobilisation:
Discontinue cast and transition to removable wrist splint as required
Precautions:
Avoid heavy gripping and loading early in this phase
Avoid repetitive impact activities
Therapy:
Commence wrist active range of motion exercises
Gentle forearm rotation exercises
Progressive functional hand use
Commence light grip strengthening
Gradual progression of activities of daily living
Criteria to Progress:
Improving wrist motion
Minimal pain
Radiographic progression towards union
Phase IV: Return to Function and Endurance (3–6 Months)
Precautions:
Gradual return to heavier activities
Avoid excessive repetitive loading until fusion established
Therapy:
Progressive strengthening and endurance training
Functional and task-specific rehabilitation
Gradual return to work and recreational activities
Criteria for Return to Activity
Radiographic union
Functional range of motion
Good strength and endurance
No significant pain or swelling
General Recommendations
Work:
Desk-based work may resume after 1–2 weeks depending on comfort.
Manual work is typically deferred until 3–6 months depending on fusion progression and job demands.
Driving:
It is important that you are medically fit to return to driving and you feel safe to control the vehicle and take evasive action if needed.
Sports and Leisure:
Lower-limb activities may resume as comfort allows.
Light hand use may commence following cast removal as directed.
Progressive return to functional and gym activities from approximately 3 months.
Higher-demand wrist loading, racquet sports, or impact activities typically from 4–6 months or longer with full recovery and surgeon clearance.
