An arthrographic study of the wrist joint, in which 65 rheumatoid wrist joints were satisfactorily shown, gave a high incidence of significant abnormalities even in the absence of clinical signs of wrist involvement. Several synovial protrusion cysts were shown and corresponded to localized clinical swellings on the volar aspect of the wrist joint. These cystic swellings may be apparent before ...

background: carpal tunnel syndrome (cts) is one of the most common musculoskeletal disorders among computer users. computer users exhibit various wrist angles while typing. dynamic changes of wrist angle may cause different degrees of median nerve compression. the objective of this study was thus to investigate the effects of the combination of wrist flexion-extension with wrist deviation on me...

BACKGROUND The wrist joint is an extremely rare site for osteosarcoma. Joint structure preservation to maintain good limb function is well described in case of knee osteosarcoma, whereas it is not described in case of wrist joint osteosarcoma. In this report, we present the first case of joint preservation surgery to treat distal radius osteosarcoma using a tumor bearing autograft treated with ...

We revisit the dimensional synthesis of a spatial two-link, two revolute-jointed serial chain for path following applications, focussing on the systematic development of the design equations and their analytic solution for the three precision point synthesis problem. The kinematic design equations are obtained from the equations of loop-closure for end-eeector position in rotation-matrix/vector...

Our understanding of wrist osteoarthritis (OA) lags behind that of other joints, possibly due to the complexity of wrist biomechanics and the importance of ligamentous forces in the function of the wrist. Scaphotrapeziotrapezoidal (STT) OA is common, but its role in wrist clinical pathology and biomechanics is unclear. We identified the prevalence of radiographic STT joint OA in our hand clinic...

BACKGROUND Elbow injuries are common in college baseball players. Pitching creates stress and fatigue in and around the elbow. Lack of joint proprioception can contribute to nonphysiological joint loading and injury. HYPOTHESIS There will be no difference in elbow joint active reproduction sense following a simulated 3-inning pitching sequence. STUDY DESIGN Cross-sectional study. METHODS ...

To find an effective way to handle wheelchairs, 3-dimensional floor reactions of the hand and angular deviation of the elbow and wrist joints during push-up motion were studied in 10 healthy men. The push-up was carried out using 3 hand positions (fist, finger and palm) and a push-up device. In all hand positions, anteroposterior force (Fx) and the mediolateral force (Fy) appeared after the ver...

Septic arthritis of the wrist can result in permanent damage to the joint, making timely diagnosis crucial to initiate empiric antibiotics and surgical intervention. Although septic arthritis is routinely included in the differential diagnosis of atraumatic wrist pain, the incidence is unknown. Unlike large joints, there is no consensus on cell count values considered pathognomonic for wrist se...

The data from 35 consecutive patients with hallux valgus undergoing triplane arthrodesis at the first tarsal metatarsal joint were studied to determine the amount of first metatarsal frontal plane rotation (supination) needed to anatomically align the first metatarsal phalangeal joint on an anterior posterior radiograph without soft tissue balancing at the first metatarsal phalangeal joint. Rad...
