Helminthostachys zeylanica (HZ), which is also called “Dao-Di-U-Gon” in Taiwan, has anti-inflammatory and antiedema effects and is commonly used to treat edema in patients with fractures. The ugonin K component of HZ can induce osteogenesis and promote bone mineralization, its therapeutic effect, however, its therapeutic effect remains unclear. Therefore, the purpose of the present study was to investigate the effect of HZ on functional recovery in patients with ankle fractures requiring surgical treatment. A double-blinded, randomized, controlled study was conducted. A total of 45 patients with ankle fractures requiring surgical treatment were assigned to either the control group (n = 23 patients), which received the oral administration of HZ placebo 1.0 g t.i.d. for 42 days continuously, or to the treatment group (22 patients), which received HZ for 42 days. The serum amino-terminal propeptide of type 1 procollagen (PINP) levels were similar in the first assessment (V1) between the control (45.90 ± 16.31 ng/mL) and treatment groups (52.61 ± 21.02 ng/mL; p = 0.240); the differences in PINP level between the third assessment (V3) and V1 were greater in the treatment group (35.84 ± 24.56 ng/mL) than in the control group (16.34 ± 11.97 ng/mL; p = 0.002). Radiographic healing time (RHT) was 9.09 ± 1.15 weeks in the treatment group, which was shorter than the 9.91 ± 0.79 weeks (p = 0.012) in the control group. Oral administration of HZ for 42 days can increase serum PINP level and reduce the RHT. Therefore, HZ can be used to treat patients with ankle fractures requiring surgical treatment. However, a larger sample size is needed in future studies. [Display omitted]
