To observe the effects of Gukang capsule treatment for elderly patients with unstable distal radius fractures, in order to investigate the auxiliary effect of traditional Chinese medicine on the surgical treatment of these patients. Methods:A total of 68 cases of elderly patients with unstable distal radius fractures who were admitted in our hospital from February 2014 to June 2016 were selected and randomly divided into experimental group and control group according to random number table method, with 34 cases in each group. Patients in both group received volar locking plate internal fixation treatment. Besides that, patients in control group received calcium carbonate tablet, 1.5g each time, 3 times each day, and patients in experimental group received Gukang capsule on the basis of the control group, 4 tablets each time, 3 times each day. Patients in both groups were treated for 2 months. The serum levels of serum tar-trate resistant acid phosphatase (TRACP5b), Procollagen type I C-terminal propeptide (PICP), bone gla protein (BGP) were detected before treatment and 1 month, 2 month after surgical treatment were detected, and the time of swelling subsided, fracture healing, hospitalization were recorded in detail. The fracture reduction quality and recovery of wrist function were evaluated at 6 months after surgical treatment. Results:Compared with the control group, the serum levels of TRACP5b of experimental group was significantly decreased, and the serum levels of PICP, BGP of experimental group were significantly increased at 1 month, 2 months after surgical treatment, with statistically significant difference (P<0.05); The time of swelling subsided, fracture healing, hospitalization of experimental group were significantly shorter than that of control group, with statistically significant difference (P<0.05); At 6 months after surgical treatment, there were statistically significant difference in palmar angle, ulnar deviation angle and radius height between the two groups (P<0.05); At 6 months after surgical treatment, the excellent rate of wrist function recovery was 79.41% (27/34) in experimental group, and 64.71% (22/34) in control group, without statistically significant difference (P>0.05). Conclusion:Gukang capsule treatment for elderly patients with unstable distal radius fractures has significant effects, which can effectively improve the state of bone metabolism, promote postoperative swelling subsided and fracture healing.
