COLLATERAL LIGAMENT INJURIES
ANATOMY
Collateral ligaments strengthen the sides of the fibrous capsule that surrounds the joints in the fingers and thumb – the metacarpophalangeal (MCP) joints, at the base of the fingers and thumb, the proximal interphalangeal (PIP) joints, nearest to the palm in the fingers, and the distal interphalangeal (DIP) joints, the second joint in the fingers. The collateral ligaments provide medial-lateral stability.
MECHANISM OF INJURY
Varus or valgus stress eg. a ball striking the end of a finger.
SYMPTOMS
Pain and tenderness over the side of the affected joint.
Impaired mobility due to pain and swelling.
Instability in more severe injuries.
TREATMENT
Please consult with your medical professional for a complete diagnosis and treatment plan.
