A 51-year-old woman experienced intermittent left hand numbness and weakness over 2 years, with a claw-hand deformity and weakness of finger abduction, adduction, and distal interphalangeal joint flexion of the medial 2 fingers. Wrist flexion produced hand radial deviation. Palmar and dorsal aspects of digits IV (medially) and V, including medial forearm, had decreased pinprick sensation. Nerve...

A Japanese family in which four patients in three generations had distal symphalangism associated with camptodactyly is reported. All of these patients had extension limitation of the proximal interphalangeal joints of the toes of both feet. Radiographs of the hands and feet, undertaken in three cases, showed no bone fusion of the distal and proximal interphalangeal joints. This malformation is...

Magnetic resonance is a great diagnostic tool in equine lameness examination. Its value is most significantly visible in evaluating distal extremities. Problems with podotrochlear apparatus, laminitis or distal interphalangeal joint osteoarthritis are the most common disorders diagnosed in equine patients. Without using magnetic resonance it was impossible to clearly assess which structures are...

Due to the growing demand for assistance in rehabilitation therapies for hand movements, a robotic system is proposed to mobilize the hand fingers in flexion and extension exercises. The robotic system is composed by four, type slider-crank, mechanisms that have the ability to fit the user fingers length from the index to the little finger, through the adjustment of only one link for each mecha...

Magnetic resonance imaging can demonstrate core lesions, dorsal tears, and sagittal splits in the deep digital flexor tendon within the hoof capsule in horses with unilateral or bilateral palmar foot pain. Abnormalities of the navicular bone can be seen in horses with no detectable radiological abnormality. Lesions of the articular cartilage and subchondral bone of the distal interphalangeal jo...

A digital mucous cyst (DMC) is clinically characterized by a round to oval, translucent, smooth nodule localized to the dorsal aspect of the distal digits near the distal interphalangeal joint. It usually presents as a solitary lesion, and multiple lesions are uncommon. An 88-year-old man presented with herpetiform translucent papules on the right thumb. We first diagnosed the lesion as mollusc...

BACKGROUND Surface replacement arthroplasty is a reconstructive alternative for the treatment of pain and deformity due to osteoarthritis and rheumatoid arthritis of the proximal interphalangeal joint of the finger. This retrospective study was performed to examine long-term outcomes of proximal interphalangeal joint prosthetic surface replacement with a proximal cobalt-chromium (CoCr) and dist...

Acute hand and wrist injuries in the athlete constitute a unique orthopaedic challenge. Because of the particular demands on the athlete (e.g., financial implications, coaching and administration pressures, self-esteem issues), a specialized management approach is often necessary. Common sites of injury include the ulnar collateral ligament of the thumb metacarpophalangeal joint, proximal inter...
