background: today application of computer in the life of people is very common and those who work with computer in especially long – term are faced with musculoskeletal pains. the aim of this study was to investigate risk factors of musculoskeletal and joint pains among computer users in rafsanjan city in the years 2012-13. materials and methods: in this descriptive study, 420 computer users we...

Carpal tunnel syndrome (CTS) is characterized by burning pain, numbness and tingling sensation in the thumb, index and middle fingers and the lateral half of the palm and progressive atrophy of the thenar muscles by compression of the median nerve within the carpal tunnel due to a variety of etiologic factors. Surgical intervention usually successfully relieves symptoms of CTS. Recently CTS has...

Carpal malalignments in malunion of distal radius fracture are considered as an adaptive response of the carpus to loss of normal architecture of the distal radius. This condition leads to mechanical overload, ligament attenuation and progressive dynamic instability around the wrist joint. Radial corrective osteotomy is suggested as a treatment option of carpal malalignment after distal radius ...

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...

The Sailfin lizard is a that has semi-aquatic life and sail fin on its tail. These lizards can be found in habitats close to water such as rivers, lakes, estuaries of mangrove forests. This study aimed observe the morphofunctional characteristic appendicular skeleton Lizard (Hydrosaurus amboinensis), associated with their function behavior. was studied by observing measuring bones make up extre...

Introduction: Although fibrosis of the subsynovial connective tissue (SSCT) is a common finding in cases of carpal tunnel syndrome, little is known about the physical properties of this tissue. We investigated the mechanical, histological and kinematic properties of carpal tunnel tenosynovium in normal human cadaver specimens, and measured the relative motion of the tendon, SSCT, and synovium i...

The purpose of this study was to investigate the gliding characteristics of flexor tendons within the carpal tunnel with varied wrist positions and tendon motion styles, which may help us to understand the relationship between carpal tunnel syndrome (CTS) and repetitive hand motion. Eight fresh human cadaveric wrists and hands were used. The peak (PGR) and mean (MGR) gliding resistance of the m...

Injuries to the scapholunate joint are the most frequent cause of carpal instability and account for a considerable degree of wrist dysfunction, lost time from work, and interference with activities. The complex arrangement and kinematics of the 2 rows of carpal bones allows for an enormous degree of physiologic motion, and a hierarchy of primary and secondary ligaments serves to balance an inh...
