Denervation for Proximal Interphalangeal Joint Osteoarthritis.

Area of Science:

• Orthopedic Surgery
• Hand Surgery
• Rheumatology

Background:

• Osteoarthritis commonly affects the proximal interphalangeal (PIP) joints.
• Pain and functional limitations significantly impact patients with PIP joint osteoarthritis.

Purpose of the Study:

• To evaluate the clinical and functional outcomes of proximal interphalangeal (PIP) joint denervation using a volar approach.
• To assess the safety and efficacy of this surgical technique for PIP joint osteoarthritis.

Main Methods:

• Retrospective review of 11 cases treated between June 2007 and June 2016.
• Data collected included visual analog scale (VAS) for pain and the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire.
• Assessment of PIP joint active range of motion.

Main Results:

• Significant improvement in VAS pain scores (7.8 to 1.4) and DASH scores (43.6 to 8.7).
• Enhanced PIP joint active range of motion from 52° to 79°.
• Minor digital paresthesia in two patients resolved spontaneously; no major complications reported.

Conclusions:

• Proximal interphalangeal (PIP) joint denervation is a safe and effective surgical option for osteoarthritis.
• The procedure yields favorable clinical results, preserving options for more aggressive interventions if necessary.
