OBJECTIVE To examine articular cartilage of the distal interphalangeal (DIP) joint and distal sesamoidean impar ligament (DSIL) as well as the deep digital flexor tendon (DDFT) for adaptive responses to contact stress. SAMPLE POPULATION Specimens from 21 horses. PROCEDURE Pressure-sensitive film was inserted between articular surfaces of the DIP joint. The digit was subjected to a load. Fin...

REASONS FOR PERFORMING STUDY Increased joint pressure has been implicated in the progression of osteoarthritis. HYPOTHESIS That intra-articular pressure in the distal interphalangeal joint (DIP) is significantly higher in legs loaded with heel up (HU), low heel (TU), lateral side up (LU) and medial side up (MU) imbalance compared to the balanced position. METHODS Twelve elbow down limbs wer...

PURPOSE To evaluate the natural history and etiology of decreased thumb interphalangeal (IP) joint flexion after volar plate fixation of distal radius fractures. METHODS A total of 46 patients who underwent volar plating of 48 distal radius fractures by a single surgeon were retrospectively studied. Of those patients, 24 (24 wrists) exhibited loss of thumb IP joint flexion (group 1) and 22 (2...

Objective: When hands suffer burns, the tendons and digital bones are rarely injured because of the quick withdrawal reflex away from the heat source. Hence, a consensus of opinion regarding the treatment of severe hand burns with osseous blood flow deficiency has not been reached among clinicians. Methods: The patient was a 28-year-old woman whose fingers were accidentally soaked in heated coo...

Injuries to the proximal interphalangeal joint (PIPJ) of the fingers are common. They occur most often following an axial impact on an extended finger. Fractures of the proximal interphalangeal joint include a wide spectrum of injuries, from stable avulsion fractures to complex fracture-dislocations. Stability of the joint is paramount in determining the appropriate treatment, which should aim ...

A 77-year-old Japanese woman developed gait disturbance during her 50s. The gait disturbance and a muscle weakness in her lower limbs gradually worsened, and she consulted our hospital at the age of 76. Neurological examination showed proximaldominant muscle weakness and atrophy, particularly in the quadriceps muscles. In her left hand, the muscle strength during finger flexion at the distal in...

An 88-year-old woman was referred for acute arthritis of the fingers. Twelve days previously, she had experienced acute pain with swelling of the right 4th proximal interphalangeal joint (PIP). Several days later, she developed a lowgrade fever and pain of the 3rd distal interphalangeal joint (DIP). She had experienced a similar attack six months earlier that had resolved within a week. Her med...

BACKGROUND In rheumatoid arthritis (RA), hand synovitis appears especially in wrist, metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joints. In hand osteoarthritis (OA), potential inflammatory changes are mainly present in PIP and distal interphalangeal (DIP) joints. Joint inflammation can be visualised by fluorescence optical imaging (FOI) and musculoskeletal ultrasound (US). OB...

This is the first reported case of sesamoid bone interposition in the interphalangeal joint of the hallux as a complication of closed reduction of a dislocated interphalangeal joint of the hallux. The case also highlights the importance of post-reduction radiographs.
