Boutonniere Deformity eMedicine Orthopedics

Boutonnière deformity (BD) can manifest acutely following trauma, but most BDs are found weeks following the injury or as the result of progressive arthritis. The proximal interphalangeal (PIP) joint of the finger is flexed, and the distal interphalangeal (DIP) joint is hyperextended (see Image 1). Treatment options depend partly on etiology of the deformity and are discussed in the sections to follow.

Intrinsic Plus Hand eMedicine Orthopedics

The intrinsic plus position is otherwise known as the safe position for hand splinting. The hand can be immobilized in this position for long periods of time without developing as much stiffness as would occur if the digits were positioned differently. In the intrinsic plus position, the metacarpophalangeal (MP) joints are flexed at 60-70°, the interphalangeal (IP) joints are fully extended, and the thumb is in the fist projection. The wrist is held in extension at 10° less than maximal.

Mallet Finger eMedicine Orthopedics

Loss of extensor tendon continuity at the distal interphalangeal joint (DIPJ) causes the joint to rest in an abnormally flexed position. This occurs with a laceration to the dorsum of the digit near the DIPJ. Mallet finger describes the condition in which the skin remains closed and the extensor tendon is either forcibly stretched or avulsed from the distal phalanx.

Mallet Fracture eMedicine Sports

The term mallet finger has long been used to describe the deformity produced by disruption of the terminal extensor mechanism at the distal interphalangeal (DIP) joint.1, 2, 3 Mallet finger is the most common closed tendon injury that is seen in athletes; this injury is also common in nonathletes after "innocent" trauma. Mallet finger has also been referred to as drop, hammer, or baseball finger (although baseball accounts for only a small percentage of such injuries).

Rheumatoid Hand eMedicine Plastics

Rheumatoid arthritis (RA) is a systemic disease that affects synovial tissue. The disease affects approximately 1% of the population, has a female predominance (female-to-male ratio of 2.5:1), and shows increased incidence with age.1 The clinical course of the disease is variable and ranges from mild, self-limited arthritis to a progressive multisystem disease.
The surgical treatments for RA include synovectomy, tenosynovectomy, tendon realignment, reconstructive surgery or arthroplasty, and arthrodesis. The main goals for surgical treatment of RA are alleviation of pain, improvement of function, retardation of the progression of the disease, and improvement of appearance.

Swan Neck Deformity eMedicine Orthopedics

Structural deformities of the digits of the hand are common in patients with rheumatoid arthritis (RA). A swan-neck deformity, typically defined as proximal interphalangeal (PIP) joint hyperextension with concurrent distal interphalangeal (DIP) joint flexion, occurs in approximately 50% of patients with RA. However, swan-neck deformity is not unique to RA, because it may also be congenital or traumatic in nature. Multiple surgical procedures are available for the correction of this digital abnormality. The deformity of the finger or fingers must be staged accurately to use the most appropriate surgical technique. The staging of the deformed finger is based on the condition of the articular cartilage—which is determined by radiography—and on the flexibility of the PIP joint.
