Abstract

Abstract:

BACKGROUND: The traditional orthopedic fixation by C-arm positioning surface is completed, but the large C-arm injury on the human body and the long fixed time increase the suffering of patients.

OBJECTIVE: To investigate the X-ray fixed in position within the orthopedic implants, navigation and effect.

METHODS: Twenty-six New Zealand white rabbits were randomly divided into C-arm machine group and X-ray group, with 13 in each group. Rabbits in both groups were used to simulate soft tissue foreign body localization, intramedullary nail implantation at distal fracture end and spinal pedicle screw entry point position. In the C-arm machine group, positioning navigation was conducted with C-arm machine. In the X-ray group, X-ray positioning navigation was used. The positioning and navigation effects were compared between the two groups.

RESULTS AND CONCLUSION: (1) Compared with the C-arm machine group, the time required for navigation in the X-ray group targeting soft tissue foreign body localization, fracture distal locking intramedullary nail implantation and pedicle screw spinal needle point location was significantly shorter (P < 0.05); navigation displacement and deviation produced were significantly less (P < 0.05). (2) These findings suggested that the X-ray positioning for orthopedic fixation method is relatively simple, with high availability, and can obtain a high performance-price ratio. Meanwhile, the X-ray localization can improve accuracy and shorten the fixed time.
