Radiographic changes in the hands of rock climbers.
Radiographs of the hands of 36 rock climbers were compared with radiographs of the hands of controls matched for age and sex. Subchondral cysts were present in the hands of 17 climbers and only two controls. Osteophytes or bony spurs were present in 14 climbers but not in any of the controls, and the only two cases of frank osteoarthrosis were in the hands of climbers. Cortical thickness of the...
متن کاملFactors influencing osteological changes in the hands and fingers of rock climbers.
This study examines the osteological changes in the hands and fingers of rock climbers that result from intense, long-term mechanical stress placed on these bones. Specifically, it examines whether rock climbing leads to metacarpal and phalange modelling in the form of increased cortical thickness as well as joint changes associated with osteoarthritis. This study also attempts to identify spec...
متن کاملChanges in EMG and Finger Force with Repeated Hangs from the Hands in Rock Climbers
The nature and degree of fatigue in muscles that control finger position during repeated sustained efforts in rock climbing have not been described. The purpose of this study was to identify changes in maximum hang time and forearm electromyogram (EMG) during repeated maximum duration hangs from a simulated rock feature. A second objective was to determine the effect of different recovery times...
متن کاملLumbrical tears in rock climbers.
Performance rock climbing places high demands on the hand and may lead to specific injuries. In a "one-finger-pocket" hold, the interphalangeal joints remain in 20-40 degrees flexion. To increase the maximum force of the holding finger by the quadriga effect, the interphalangeal joints of the adjacent fingers become almost maximally flexed. Holding a "one-finger-pocket" with the ring or small f...
متن کاملFingertip injuries in rock climbers.
The sport of rock climbing has undergone a significant change in recent times with technically harder climbs being attempted more often. This has meant that climbers have taken to more training including weight training, using artificial climbing walls and the more traditional 'bouldering' i.e. training on natural outcrops and boulders. This increase in standards has led to injuries associated ...
