Study on Effect of Artificial Hip Joint Replacement on Blood Vessel CECs, EPCs and Serum Osteocalcin of Patients with Traumatic Osteonecrosis of Femoral Head

Abstract

Study the effects of artificial hip joint replacement on blood vessel CECs, EPCs and serum osteocalcin of the patients with traumatic osteonecrosis of femoral head. Examine pre-operative and post-operative blood vessel CECs, EPCs and serum osteocalcin levels of the patients in both groups and statistically analyze them. Before the operation, the Harris and VAS of both groups are identical; after the operation, the Harris scores of the patients in Observation Group are obviously higher than those of Control Group and the VAS scores are obviously lower than those of Control Group, of which the difference is statistically significant (P<0.05). Before the operation, the blood vessel CECs and EPCs levels of both groups are identical; after the operation, the blood vessel CECs of the patients in Observation Group are obviously lower than those of Control Group, the numbers of blood vessel EPCs are obviously higher than those of Control Group, and the difference of blood vessel CECs and EPCs levels of the patients in both groups is statically significant (P<0.05). Before the operation, the serum osteocalcin levels of the patients in both groups are identical; after the operation, the serum osteocalcin levels of the patients in Observation Group are obviously higher than those of Control Group, of which the difference is statistically significant (P<0.05). Artificial hip joint replacement can affect blood vessel CECs, EPCs and serum osteocalcin of the patients and accordingly promote recovery of the patients with traumatic osteonecrosis of femoral head.
