Background The paradoxical demands of stability and mobility reflect the purpose and
function of the human thumb. Its functional importance is underscored when a thumb is …

In thumb carpometacarpal (CMC) instability, laxity of the surrounding ligaments of the joint
leads to pain and weakness in grip and pinch strength, making the patient susceptible to …

Purpose The respective roles of the dorsoradial (DRL) and anterior oblique (AOL) ligaments
in stability of the highly mobile trapeziometacarpal (TMC) joint remain disputed. Earlier …

To determine the pathogenesis of trapeziometacarpal (TMC) joint instability, which leads to
osteoarthritis, we investigated the anatomical relationships among the surrounding …

This article describes the anatomy and biomechanics of the thumb CMC joint, which is also
often referred as the thumb trapeziometacarpal joint. The complexity of its anatomy, function …

The anterior oblique ligament (AOL) and the dorsoradial ligament (DRL) are both regarded
as mechanical stabilizers of the thumb carpometacarpal (CMC) joint, which in older women …

Purpose the aim of this study was to evaluate the effectiveness of interposition arthroplasty
of the trapeziometacarpal (TMC) joint with pyrolitic carbon implants for the treatment of TMC …

Objective Osteophyte formation is a critical part of the degeneration of a joint with
osteoarthritis (OA). While often qualitatively described, few studies have succeeded in …

The basal joint complex of the thumb provides the framework necessary for function of the
human hand. Although its unique saddle articulation allows for a wide range of motion …

The purpose of this study was to define the normal thumb carpometacarpal joint kinematics
in-vivo during opposition and abduction using four-dimensional computed-tomography in …
