carpal fracture-dislocation is regarded as an unusual orthopedic injury and, thus, orthopedic surgeons are less experienced in dealing with and treating these fractures and dislocations. we report a 20-year-old worker man suffering from an unusual carpal fracture-dislocation. there was trans-scaphoid fracture and lunate dislocation with other carpal proximal bones toward volar of the wrist. two...

The purpose of the study was to identify unique features of the normal osteology and radiologic anatomy of the thoracic limb of the meerkat or suricate (Suricata suricatta), as no comprehensive information has been published. Bone specimens of 19 suricates were studied. Individual bones of the manus of one preserved carcass were studied in situ. Radiographic evaluation was performed in six anim...

The tetrapod forelimb is one of the most versatile structures in vertebrate evolution, having been co-opted for an enormous array of functions. However, the structural relationships between the bones of the forelimb have remained largely unchanged throughout the 375 million year history of Tetrapoda, with a radius and ulna made up of elongate, paralleling shafts contacting a series of shorter c...

Skeletal age assessment is one of the important applications of hand radiography in the area of pediatric radiology. Feature analysis of the carpal-bones can reveal the important information for skeletal age assessment. The present work in this paper faces the problem of the detection of carpal -bone features from X-ray image. A novel and effective segmentation technique is presented in this wo...

Carpal tunnel syndrome (CTS) is by far the most common cause of median nerve damage. The carpal tunnel is an anatomical compartment of the hand; it is bounded on three sides by carpal bones which form an arch, and on the palmar side by the transverse carpal ligament. Pathogenesis CTS results from compromise of median nerve function at the wrist, caused by increased pressure in the carpal tunnel...

The scaphoid is the most common of the carpal bones to fracture; upper limb fractures are associated in 5-10% of cases, and around 2% of the concomitant fractures are of the distal radius. One case of bilateral carpal scaphoid fractures associated with bilateral distal radius fractures is presented. Radiographs showed displaced Salter-Harris Type II radius fracture and nondisplaced transverse m...
