INTRODUCTION The Internet has become a heavily used source of health information. No data currently exists on the quality and characteristics of Internet information regarding carpometacarpal (CMC) arthritis. METHODS The search terms "cmc arthritis," "basal joint arthritis," and "thumb arthritis" were searched using Google and Bing. Search results were evaluated independently by four reviewer...

prom cadaver dissections of the recurrent proximal fragment due to traction of the abductor motor branch of the median nerve, we pollicis longus m u ~ c l e ~ , ~ . The small fmgment is determined the exact relationship of its thus left along the palmar aspect. terminal branches at the base of the thumb. This enabled us to surgically approach the first Bennett, in 1886, advocated closed reducti...

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 ...

Dislocation of the first carpometacarpal (CMC) is a rare occurrence. Treatment of this dislocation varies from closed reduction and casting to ligament repair. Neglected dislocation or incomplete reduction of the 1(st) CMC cause chronic instability and painful arthritis, muscle imbalance and decreased grip force. In our study 6 patients is evaluated that were visited in less than 24 hours from ...

Although the etiology of osteoarthritis of the thumb carpometacarpal (CMC) joint remains unclear, some theories have focused on variations in the local anatomy of the abductor pollicis longus tendon insertion. This cadaver study of 68 specimens analyzed the relationship between a thenar insertion of an accessory abductor pollicis longus tendon and the presence and severity of thumb CMC osteoart...

Hand dysfunction is commonly linked to ligamentous laxity (Murray 2006). The carpometacarpal joint (CMCJ) of the thumb may be particularly susceptible to weakened ligamentous constraints in the Ehlers-Danlos syndrome (Moore et al 1985). Symptoms may only present if the joint has been subject to excessive trauma, overuse or misuse and thus strains of the surrounding muscles and ligaments may hav...

OBJECTIVE To examine the association between hand and knee osteoarthritis (OA) in a community based population. METHODS Radiographs of 695 participants aged > or = 40 years in the Baltimore Longitudinal Study of Aging were read for changes of OA, using Kellgren-Lawrence grade > or = 2 as the case definition. RESULTS Logistic regression analyses, adjusting for age, gender and body mass index...

BACKGROUND Analysis of arthrokinematics may have clinical use in the diagnosis of dynamic instability of the thumb and wrist. Recent technological advances allow noninvasive, high-resolution imaging of skeletal (thumb and carpal bones) structures during motion. QUESTIONS/PURPOSES The primary purpose of this study is to define the arthrokinematics, estimated joint contact patterns, and distrib...
