Fracture of Acetabulum Clinical Trial
Official title:
Treatment of Acetabular Posterior Wall Fracture With Anatomical Locking Plate
The purpose of this study is to determine whether this new anatomical locking plate is more effective and easy to operate than other plate in the treatment of acetabular posterior wall fracture.
Acetabular fractures were very common in high-energy injury, because of the anatomic of
acetabular was in deep location and the complex form cause the diagnosis and treatment was
difficult. For most of displaced acetabular fractures, the preferred treatment is open
reduction and internal fixation. The purpose of surgery is to restore acetabular integrity
and stability, allow early exercise, decrease complication. Acetabular posterior wall
fractures were the most common, the current clinical application fixation of acetabular
fractures were common plate and reconstruction steel plate. But when the acetabular
posterior wall was fracture, some patients were not satisfied after surgery. The reason is
mainly because the reconstruction plate need remoulding in surgery, and it not only led to
the extension of operation time, but also cause poor attach. Otherwise, the reconstruction
plate need location the angle of screw in surgery. If the operator lack of experience will
make into the harm surrounding vessels and nerves. Some research has achieved the
improvement from the anatomy of acetabular fractures in the locking plate. But there is not
any plate match with the anatomy of the acetabular posterior wall.
This anatomical bone plate was designed base on before plate and had patent protection which
is used in clinical trial. It was a new type of internal fixation of acetabular posterior
wall fracture, this plate improve the shortcomings of existing technology, provides a
pre-formed anatomical fixation plate , the direction of the locking screw holes. This design
provide a better attach of acetabular posterior wall, more safe use the screw, making more
stable and reliable fixation. This fixation plate was not only suitable for an experienced
doctor, but also suitable for a less experienced doctors in theory. They can quickly and
accurately fixed in its correct position, thus this fixation plate have advantages of
improve surgical success rates, shorter hospital stay, reduce disease painful and it can
used in all adult patients.
