ABSTRACT
BACKGROUND:
There are currently various surgical methods of patel a fracture, and they have advantages and disadvantages, thus cannot wel meet the requirements of patients.OBJECTIVE:
To evaluate biomechanical properties of internal fixation plate to treat patel ar fracture and to provide theoretical evidence for clinical application.METHODS:
According to the statistics of patel a in the Chinese population, a titanium al oy spider internal fixation plate was designed and manufactured for the treatment of patel ar fractures. Knee joint specimens in six fresh cadavers were randomly divided into two groups and the comminuted fracture model of patel a were established. The models were fixed with internal fixation plate of patel a and NiTi patel ar concentrator. Biomechanical tests were carried out to compare the biomechanical properties. RESULTS ANDCONCLUSION:
Both the two fixation methods could meet the 1-kN quadriceps femoris contraction. The internal fixation plate of patel a was superior to NiTi patel ar concentrator in the patel ar isolation shift, muscle strength and joint strength, as wel as mechanical properties of patel a-point surface. There were significant differences between the two groups (P<0.05). The internal fixation plate of patel a is designed in accordance with the anatomical and biomechanical properties of the patel a, the fixation strength can completely meet clinical requirement and deserve further application.
