ABSTRACT

BACKGROUND:

Nano-hydroxyapatite helps to improve the mechanical properties of bone implants.

OBJECTIVE:

To study the clinical effect of nano-hydroxyapatite artificial bone on col apsed fracture of the tibial plateau.

METHODS:

Fourteen cases of col apsed fracture of the tibial plateau combined with bone defects from March 2010 to September 2012 were analyzed retrospectively. The bone defect range was from 1.5 cm×1.0 cm to 3.1 cm×4.5 cm. Al patients were treated with nano-hydroxyapatite artificial bone at an implant amount of 5-14 g. Clinical and X-ray observations were applied at 1 week, 1 month and 3 months postoperatively. Hospital for Special Surgery scores were employed for recovery of knee function. RESULTS AND

CONCLUSION:

The patients were fol owed up for 12-27 months. Except for one case of a smal amount of wound exudates, no general side effects occurred in 13 cases. X-ray photo showed an integrity interface between nano-hydroxyapatite artificial bone and host bone at 3 months after treatment. Primary healing was obtained in al cases without any complications. Hospital for Special Surgery score was increased to (88.7±4.3) points at 1 year later. These findings indicate that the nano-hydroxyapatite artificial bone has a good biocompatibility and biomechanics, and it may be an ideal artificial bone for repairing col apsed fractures of the tibial plateau.
