Clinical Studies of Treated Severe Dislocation of Acromioclavicular Joint by Coracoclavicular Fixator;

Biomechanical Study and Clinical Application of Multiclaw Cliplike Cervical Spinal Fixator;

In general,previous turbine foundation adopted refined chiseling and adjustable-oblique plates,while 1 000 MW USC turbine in Datang Chaozhou Sanbaimen Power Plant is designed to use adjustable fixators foundation.

Objective To discuss the management of spondylolysis with multiclaw cliplike cervical spinal fixer in middle-aged and old patients.

The strains on the shin bone and on the Shshi needle of the unilateral external fixation were measured and regular patterns of strains under five applied force conditions were analyzed.

Causes and countermeasures for the internal fixators loosening or rupturing after internal fixation with AF system for thoracolumbar fractures;

Objective To explore the causes and countermeasures of the internal fixators loosening or rupturing after internal fixation for thoracolumbar fractures.

AIM To study the pullout force of pedicle screws with different forms of thread and to supply the experimentdata for the clinical application of transpedicular internal fixators.

Three dimensional finite element analysis on the pressure of femoral head affected by dynamic hip external fixator;

Treatment of metacarpal and phalangeal fractures with micro-external fixator;

Using external fixator effectively in the treatment of trauma;

Treatment of intra-articular calcaneal fractures with external fixators;

The treatment of the infected tibial nonunion by open bone grafting and AO external fixators

[Method]In accordance with pathological changes and requirements for correctioning talipes equinus,cavus,calcaneus and forefoot varus or valgus,four standard external fixators were designed on the basis of Ilizarov apparatus assembly and tested biomechanically to correct the above.
