Low-intensity extracorporeal shock wave therapy for midshaft clavicular delayed union: A case report and review of literature

BACKGROUND One of the most common complications following surgery for midshaft clavicle fracture is nonunion/delayed union.Extracorporeal shock wave therapy(ESWT)is an alternative to promote new bone formation without surgical complications.To date,no literature has reported low-intensity ESWT(LI-ESWT)in delayed union of midshaft clavicle fracture.CASE SUMMARY We reported a 66-year-old Chinese amateur cyclist with clavicle delayed union treated with 10 sessions of LI-ESWT(radial,0.057 mJ/mm^(2),3 Hz,3000 shocks).No anesthetics were applied,and no side effects occurred.At the 4 mo and 7 mo follow-ups,the patient achieved clinical and radiographical recovery,respectively.CONCLUSION In conclusion,our findings indicated that LI-ESWT could be a good option for treating midshaft clavicular delayed union.

Clinical Research on Zishengukang Pill(滋肾骨康丸)Used to Treat Delayed Union of Fracture

Objective:To observe the curative effect of Zishengukang Pill(滋肾骨康丸) on delayed union of fracture.Methods:Sixty-four patients with delayed union of fracture were randomly divided into a control group of 32 cases treated with Western medicine and a treatment group of 32 cases treated with Western medicine and Zishengukang Pill.After 3 courses of treatment with 30 days as a course,the curative effects in the two groups were evaluated and their clinical symptoms,union rate and union time of fracture were compared.Results:The treatment resulted in cure in 25 cases,improvement in 6 cases and ineffectiveness in 1 case with the effective rate at 96.8% in the treatment group,higher than 81.3% in the control group(P<0.05).The union rate of fracture in the treatment group was higher than that in the control group(34.3% vs.12.5%,P<0.05).The union time of fracture in the treatment group was shorter than that in the control group((4.0±1.7) months vs.(5.0±1.4) months,P<0.05).Conclusion:Zishengukang Pill with obvious curative effect in the treatment of delayed union of fracture is worth popularizing.
