PURPOSE To investigate whether palmaris longus interposition or flexor carpi radialis ligament reconstruction and tendon interposition improve the outcome of trapezial excision for the treatment of basal joint arthritis after a minimum follow-up of 5 years. METHODS We randomized 174 thumbs with trapeziometacarpal osteoarthritis into 3 groups to undergo simple trapeziectomy, trapeziectomy with...

Background Hand osteoarthritis (HOA) is a complex degenerative pathology with sometimes noisy joint manifestations that can mimic inflammatory rheumatism. The osteoarticular ultrasound, valuable addition to the clinical examination, remains little used for diagnosis and monitoring HOA. Objectives objective of our study analyze ultrasound characteristics arthritic hands OA in order know lesions ...

The results of operative treatment of 21 patients with intraarticular fractures of the thumb metacarpal bone are presented. In 14 patients closed reduction was performed followed by percutaneous fixation with one or two K-wires through the metacarpal shaft to the trapezium. In five delayed cases, in which closed reduction was unsuccessful, open reduction and K-wire pinning was performed. After ...

the rank-k numerical range has a close connection to the construction of quantum error correction code for a noisy quantum channel. for noisy quantum channel, a quantum error correcting code of dimension k exists if and only if the associated joint rank-k numerical range is non-empty. in this paper the notion of joint rank-k numerical range is generalized and some statements of [2011, generaliz...
