|May 1, 1975
Summary
Properly treating proximal interphalangeal (PIP) joint injuries is crucial to prevent hand disability. Early motion after 3 weeks and using the intrinsic plus position for immobilization are key to successful PIP joint rehabilitation.
Area of Science:
- Orthopedics
- Hand Surgery
- Rehabilitation Medicine
Background:
- Proximal interphalangeal (PIP) joint injuries can lead to significant hand disability.
- Flexion contractures of the PIP joint severely impair hand function.
Purpose of the Study:
- To define PIP joint injury types and appropriate treatments.
- To emphasize preventing prolonged joint immobilization.
- To advocate for the intrinsic plus position in PIP joint rehabilitation.
Main Methods:
- Clinical experience review.
- Experimental biomechanical studies.
Main Results:
- Early healing of PIP joints is complete by 3 weeks, allowing safe initiation of active motion.
- Immobilization beyond 3 weeks increases the risk of extensor and flexor contractures.
- The intrinsic plus position is superior to the "position of function" for preventing PIP joint contractures.
Conclusions:
- Accurate PIP joint injury diagnosis and timely treatment are essential.
- Early active motion, typically initiated after 3 weeks, is vital for preventing long-term impairment.
- The intrinsic plus position is recommended for immobilizing the metacarpophalangeal (MP) and PIP joints to prevent contractures.
