OE Journal. 2014;2(9):25 J Bone Joint Surg Am. 2002 Dec;84-A(12):2123-34450 patients with an open tibial fracture were randomized to receive the standard of care with either intramedullary nail fixation and routine soft-tissue management (the control group), an implant containing 0.75 mg/mL of rhBMP-2 alongside the standard care, or an implant containing 1.50 mg/mL of rhBMP-2 alongside the standard care. The rhBMP-2 implant was placed over the fracture at the time of wound closure. At 12 months, the 1.50-mg/mL rhBMP-2 group had a 44% reduction in the risk of failure, significantly fewer invasive interventions and hardware failures, faster wound-healing and significantly faster fracture healing than the control patients. .

مؤشر الهشاشة هو أداة تساعد في تفسير النتائج المهمة، وتوفر مقياسًا لقوة النتيجة. ويمثل مؤشر الهشاشة عدد الأحداث المتتالية التي يجب إضافتها إلى نتيجة ثنائية التفرع لجعل النتيجة غير مهمة. يمثل الرقم الصغير نتيجة أضعف ويمثل الرقم الكبير نتيجة أقوى.
لماذا كانت هناك حاجة لهذه الدراسة الآن؟
Open tibial fractures are associated with a high rate of complications, including delayed bone union and nonunion. Secondary interventions to promote union of open tibial fractures are associated with high rates of patient morbidity and reduced quality of life. Recombinant human bone morphogenetic protein-2 (rhBMP-2) has shown promise in animal and human studies as an osteoinductive agent and it is thought to have a positive role in improving union and reducing secondary interventions. This study was needed to assess the safety and efficacy of rhBMP-2 in the treatment of open tibial fractures.
ما هو سؤال البحث الرئيسي؟
In patients with an open tibial fracture, what is the safety and efficacy of an rhBMP-2 implant based on dose and compared to standard of care alone over 12 months?
- The percentages of patients requiring secondary interventions for fracture healing were 26% and 37% in the higher and lower dose groups respectively, compared with 46% in the control group (p = 0.0004).
- The number and the invasiveness of these interventions were significantly lower in the higher dose group than in the control group (p=0.0326 for number and p=0.0264 for invasiveness).
- Among the higher dose group, there was a significant 44% reduction in the risk of secondary intervention compared with the control group (p=0.0005; relative risk=0.56; 95% confidence interval: 0.40-0.78).
- At 6 months, the healing rate observed in the higher dose group was 21% higher than that in the control group (p=0.0008). Kaplan-Meyer survival analysis indicated that the time to fracture healing was shorter in the higher dose group than in the control group (p=0.0022). This significance was not seen in the lower dose group.
- 32 patients (22%) in the control group had hardware failure compared with 16 patients (11%) in the higher dose group (p=0.0174).
- 83% of the patients in the higher dose group had soft-tissue healing 6 weeks after wound closure compared with 65% of the patients in the control group (p=0.0010).
ما الذي يجب أن أتذكره أكثر؟
rhBMP-2 shows a significant and dose-dependent effect on improving the rate of fracture and wound healing, and reducing the risks of secondary intervention and hardware failure in open tibial fractures over 12 months.
كيف سيؤثر ذلك على رعاية مرضاي؟
Patients may benefit from an implant of rhBMP-2 along with standard care for open tibial fractures to reduce the risk of complications over 12 months and improve the rate of healing. Additional studies may be needed with longer-term follow-up and assessment of functional criteria.
