Joint injection of the wrist and hand region is a useful diagnostic and therapeutic tool for the family physician. In this article, the injection procedures for carpal tunnel syndrome, de Quervain's tenosynovitis, osteoarthritis of the first carpometacarpal joint, wrist ganglion cysts, and digital flexor tenosynovitis (trigger finger) are reviewed. Indications for carpal tunnel syndrome injecti...

UNLABELLED First carpometacarpal osteoarthitis is frequent and surgery may be necessary if medical treatment is not efficient. Trapeziometacarpal arthroplasty, trapeziometacarpal arthrodesis and trapezectomy may be proposed. These surgical solutions may modify the carpometacarpal kinematics of the thumb. However, no clinical tools are currently available to assess these modifications. The goal ...

Double dislocations of finger joints are rare. An unusual case of a simultaneous Bennett's fracture/dislocation ofthe carpometacarpal joint and a dorsal dislocation of the metacarpophalangeal joint of the same thumb, and the management of this injury are reported. The patient had an excellent functional result.

QUESTION In people with thumb carpometacarpal osteoarthritis, does radial nerve mobilisation to the affected hand reduce pressure pain sensitivity in the contralateral hand? DESIGN Secondary analysis of data from a randomised trial with concealed allocation, assessor blinding, and intention-to-treat analysis. PARTICIPANTS Sixty people with thumb CMC osteoarthritis in the dominant hand aged ...

The effect of correction of metacarpophalangeal (MCP) joint hyperextension on the outcome of reconstructive surgery for basal joint osteoarthritis of the thumb was studied. Impairment, pain and satisfaction were similar after a combined surgical treatment of MCP hyperextension and basal thumb osteoarthritis in 33 patients, as in a series of 233 patients at the same institution after osteoarthri...

Thumb opposition is essential for grasping, and involves the flexion abduction of carpometacarpal metacarpophalangeal joints thumb. The high number degrees freedom thumb in a fairly small space makes vivo recording its kinematics challenging task. For this reason, along with very limited independence movement joint, many devices do not implement sensors to measure such movement, which may lead ...

Most researchers have modelled the thumb as three rigid links with connections of two universal joints (carpometacarpal joint and metacarpo-phalangeal joint), and a hinge joint (interphalangeal joint). Although this produces the required number of degrees of freedom, the resulting motion is not anatomically accurate. In this work, the thumb is modelled as a five-link manipulator with the virtua...
