Stener later described a lesion observed in many cases of complete rupture of the ulnar collateral ligament of the thumb
metacarpophalangeal joint. (5) A Stener lesion is an adductor aponeurosis interpositioned between the distally avulsed ulnar collateral ligament and the ligament's insertion into the base of the proximal phalanx of the thumb.
Conventional radiography requires a MRI-estimated bone volume loss of 20% to 30% to allow certain detection of bone erosions in rheumatoid arthritis
metacarpophalangeal joints. Arthritis Res Ther 2006;8:R59.
For the accomplishment of this study,
metacarpophalangeal joints of five adult horses were collected from an abattoir in Brazil.
Displacement of the ruptured ulnar collateral ligament of the
metacarpophalangeal joint of the thumb.
(13-15) Repair of collateral ligaments of the
metacarpophalangeal joint in human fingers, which is anatomically similar to the intertarsal joint of the bird, involves ligament repair preferentially.

metacarpophalangeal joint of the right index finger.
LJM usually begins at the fifth interphalangeal joints and extends radially, affecting other interphalangeal and
metacarpophalangeal joints. Long-term glycemic control influences the onset of LJM, and the incidence of LJM is greater in patients with a poor metabolic control [4, 5].
Another possible aspect is the involuntary finger abduction during the wrist movements since the EDC is also related to the abduction/adduction of the
metacarpophalangeal joints.
The arthritis recognised as being associated with haemochromatosis most closely resembles osteoarthritis, but is distinctive in occurring at a younger age and involving some joints not usually affected by osteoarthritis; particularly the
metacarpophalangeal joints in the hands, and the ankles.
Mishra's 1st test: The
metacarpophalangeal joints of all fingers are passively hyperextended by the examiner and the subject is asked to actively flex the wrist (Mishra, 2001) (Fig.
Proximal interphalangeal and
metacarpophalangeal joints are primarily involved (3, 4).
Unreduced dislocations have definite functional disability with a decreased range of movement at the
metacarpophalangeal joints and a poor grip [8].
