PURPOSE Idiopathic osteoarthritis (OA) of the thumb carpometacarpal (CMC) joint is a common disabling disease that often causes pain and motion loss. The aims of this study were to characterize the multidimensional motion capability of the thumb CMC joint in a group with severe CMC OA and to compare it with a control group. METHODS We included 15 subjects with stage III/IV CMC OA according to...

With lumbar epidural anaesthesia, big toe skin temperature increases and is associated with a compensatory decrease of thumb temperature. The purpose of the present study was to examine whether thumb-big toe temperature differences were affected by age. Following the attachment of temperature probes at the digital pad of the right big toe and the right thumb, lumbar epidural anaesthesia at L2/3...

The use of the abductor digiti minimi transfer to restore opposition in patients with hypoplasia of the thumb has been widely described in the literature. It has been found to be effective in restoring abduction, but less so in restoring the rotational component of opposition. In cases where there is concomitant supination of the thumb, abductor digiti minimi transfer alone would not result in ...

Gamekeeper’s thumb is used to describe an acut or chronic injury to Ulnar Collateral Ligament (UCL) of thumb. We present the Magnetic Rezonance İmaging (MRI) findings of a rare case with gamekeeper’s thumb. MRI allows optimal detection and evaluation of most soft-tissue and bone lesions in the traumatic finger, including injuries the collateral ligaments.

The effects of cannulation of the radial artery were studied in 23 patients. Distal arterial pressure on the thumb, measured during radial or ulnar artery compression, was compared with the result of a modified Allen test performed before operation. Distal arterial pressure on the thumb was monitored for approximately 10 days after removal of the cannula. It was found that radial artery thrombo...

Raoultella species are Gram-negative, non-motile bacilli primarily considered to be environmental bacteria. Raoultella planticola is a rare cause of human infections. We report a case of serious soft-tissue infection in a young male tiler who presented with cellulitis of his left thumb. He had sustained a crush injury to his left thumb 10 days earlier in a soiled environment. He noted a minor b...

QUESTION What is the effectiveness of 12 weeks of nightly stretch in reducing thumb web-space contracture in people with neurological conditions? DESIGN Assessor-blinded, randomised controlled trial. PARTICIPANTS Forty-four (one dropout)community-dwelling patients with a neurological condition (14 stroke, 7 traumatic brain injury, 23 spinal cord injury) who had uni or bilateral thumb web-sp...

Thumb duplication is a rare anomaly. Here we describe two neonatal cases of thumb duplications, one type II and the other IV. Seven types have been described in medical literature. Radiological assessment important differentiating between these types.

We present a simple kinematic model of the thumb for the animation of virtual characters. The animation is made through a pure kinematics approach, thus needing very precise limitations on the rotations of the thumb to be realistic. The thumb is made opposable thanks to the addition of two bones simulating the carpometacarpal complex.
