A swan-neck or boutonniere deformity occurs in approximately half of patients with rheumatoid arthritis. The cause of boutonniere deformity is chronic synovitis of the proximal interphalangeal joint. Swan-neck deformity may be caused by synovitis of the metacarpophalangeal, proximal interphalangeal, or distal interphalangeal joints. Numerous procedures are available for the operative correction...

There are different biometric modalities used to identify person which includes palmprint, face, fingerprint, iris and hand geometry. Apart from these biometric modalities, finger knuckle print also used as one of the cost effective biometric identifier. Finger knuckle print is defined by the back side of fingers. On the back side of fingers there are three joints named as Metacarpophalangeal (...

background lesions in peripheral nerves are highly prevalent in the upper extremity. the present study compares different tendon transfer surgeries in patients with radial nerve palsy. methods fifty patients with radial nerve palsy were randomly selected among patients who referred to tehran 15th khordad hospital during 2006-2011. they were divided into two groups of 17 and 33 subjects. single ...

Disruption of the finger’s extensor apparatus at its terminal portion, causing inability to extend distal interphalangeal joint (abbreviation: DIP) and dropping of the distal phalanx, results with well known „mallet finger” deformity. This deformity can be caused by simple rupture of extensor apparatus, or avulsion fracture of the dorsal rim of the articular surface of distal phalanx. Sudden, f...

1063-4584/$ – see front matter 2011 Osteoarthritis doi:10.1016/j.joca.2011.10.008 The challenge of disease definition in osteoarthritis (OA) continues to grow. As described by Pereira et al., in a recent issue of Osteoarthritis and Cartilage (OAC), there are substantial differences in prevalence and incidence estimates when defining OA by radiographic changes alone, as symptomatic OA (requiring...

Shortening of the deep digital flexor tendon was performed by tenotomy, overlapping and anastomosis. The procedure was performed on a two-year-old Quarter Horse Mare with distal interphalangeal joint hyperextension with subluxation and metatarsophalangeal joint hyperextension. These problems originated from damage to the digital flexor tendons, presumably due to previous distal limb trauma. The...

[Purpose] The present study attempted to measure two-point discrimination in the upper extremities of healthy Koreans in their 20's. [Subjects and Methods] Using a three-point esthesiometer, we conducted an experiment with a group of 256 college students (128 male and 128 female), attending N University in Chonan, Republic of Korea. [Results] Females showed two-point discrimination at a shorter...

The authors report the case of a 39-year-old woman with pain in the right dominant hand after initiating a crafts course. Clinical examination revealed tenderness on the volar side of the thumb and wrist. Simultaneous flexion of the distal interphalangeal joint of the index finger with flexion of the interphalangeal joint of the thumb was observed. Operative procedure confirmed the presumed dia...

DESCRIPTION A 26-year-old right-handed man presented with pain in his right ring finger after a physical altercation. Deformity and swelling in the distal interphalangeal (DIP) joint was evident. There was no open injury or sensory loss; flexion and extension were limited secondary to pain. X-ray showed posterior dislocation of the ring finger DIP joint without fracture.
