Jaccoud's arthropathy is characterised by severe deformation of the hands (ulnar deviation, swan neck deformities, and Z deformity of the thumb) and feet with multiple non-erosive subluxations, mild aching and little or no evidence of synovitis (Envision the Grandma/Grandpa zig zag collapse) This is similar to what is seen with weakness or paralysis of the ulnar nerve innervated thumb muscles, but the collapse itself is secondary to the shifting moment arms of the muscles, particularly those that flex the CMC, as opposed to other mechanical ills the thumb, a cycle of MP joint flexion and IP joint hyperextension is initiated.5,6 In time, the IP joint deformity approximates the MP joint deformity, and the result is often a 90°/90° deformity.5,6 Other less common mechanisms for a boutonniere thumb deformity include MP flexion secondary to rupture of the EPL tendon at the wrist and IP. The collapsed thumb or Z deformity (first metacarpal adduction and MCP hyperextension) is a problem never adequately addressed. I have asked the panelists to comment on their treatment of choice..

Z deformity of the thumb prevents pinching because the force of the tendons causes the thumb to collapse into MCP flexion and IP hyperextension. Thumb function is important for opposition, which is essential for pinches and grips. Therefore, this deformity can severely interrupt activities of daily living requiring opposition Swan-neck deformity: The base of the finger and the outermost joint bend, while the middle joint straightens.

Claw toe deformity: The toes are either bent. True swan-neck deformity does not affect the thumb, which has only one interphalangeal joint. However, severe hyperextension of the interphalangeal joint of the thumb with flexion of the metacarpophalangeal (MCP) joint can occur; this is called a duck bill, Z (zigzag) type, or 90 °-angle deformity.With simultaneous thumb instability, pinch is greatly impaired True swan-neck deformity does not affect the thumb, which has one less joint than the other fingers. However, in a variant of swan-neck deformity, called duck-bill, Z (zigzag) type, or 90°-angle deformity, the top joint of the thumb is severely overstraightened with a bending in of the joint at the base of the thumb to form a 90° angle

Outcomes were assessed by correction of Z deformity during pinch, tendon transfer insertion pullout during early active mobilization, range of motion at the thumb metacarpophalangeal and interphalangeal joints, and postoperative treatment time Deformity: In the later stages of the condition the thumb joint may collapse inwards into a subluxed position (see diagram). The exercises, joint protection techniques and the use of assistive devices and splints (as described in this booklet) can help to relieve these symptoms and slow the progression of this condition Boutonnière deformity is generally caused by a forceful blow to the top (dorsal) side of a bent (flexed) middle joint of a finger.
