Finger joint arthroplasty is surgery to replace a damaged finger joint with an implant. It may be considered when arthritis or an injury causes persistent pain and loss of function. The procedure aims to reduce pain while preserving useful joint motion.
read more about finger joint arthroplasty ...A surgeon may recommend replacement when nonsurgical treatment no longer controls symptoms. The condition of the bones, tendons, and ligaments affects whether an implant is suitable. Joint fusion may be a better option for some fingers or joints.
The surgeon removes damaged joint surfaces and prepares the adjoining bones. An implant is placed to form a new joint surface. The implant type and surgical approach depend on the joint and the patient's needs.
A splint may protect the finger after surgery. Hand therapy guides movement and helps manage swelling and stiffness. Activity limits depend on the implant, the stability of the joint, and the surgeon's instructions.
Possible complications include infection, stiffness, and joint instability. An implant can loosen, wear, or break over time. Nerve or tendon injury and continued pain are also possible.
Not necessarily. Pain may improve, but the amount of motion after surgery varies.
No. Arthroplasty uses an implant to preserve movement, while fusion joins the bones so the treated joint no longer moves.
Not every joint is a good candidate. The surgeon considers the joint involved, its stability, and the demands placed on the hand.
Implant lifespan varies. Wear, loosening, or breakage may eventually require further treatment.
