Objective: The aim for this trial was to preliminarily evaluate the effectiveness and safety of transcutaneous electrical acupoint stimulation (TEAS) for bone loss in patients with immobilization after surgical fixation of ankle and foot fractures.
Methods: A total of 80 patients with immobilization after surgical fixation of ankle and foot fractures were randomly divided into an intervention group (n=40) or control group (n=40). The intervention group was given TEAS treatment combined with routine orthopedic treatment, and the control group was given only routine orthopedic treatment. The CT attenuation values, bone turnover markers (ALP, PINP, BGP, CTX, Ca/Cr), bone mineral density (BMD), blood phosphorus, and blood calcium were observed and compared between the two groups at 8 weeks. This was a prospective study. The protocol was registered in the Chinese clinical trial registry (No. ChiCTR2000039944).
Results: The CT attenuation values of the intervention group decreased more than those of the control group (P<0.05), however the between group differences in ALP, BGP, Ca/Cr, CTX and BMD (all P>0.05) were not statistically significant. Three mild adverse events were recorded.
Conclusion: TEAS treatment may confer additional benefits for bone loss in patients with immobilization after surgical fixation of ankle and foot fractures. Since this was a pilot study, the efficacy of TEAS requires further evaluation through full-scale randomized controlled trials.
