Decrease in outpatient department visits and operative interventions due to bisphosphonates in children with osteogenesis imperfecta.

INTRODUCTION

Bisphosphonates are currently the medical treatment most often used in children with osteogenesis imperfecta (OI). The purpose of this retrospective pre-post study was to evaluate the efficacy of treatment with bisphosphonates. We measured the effect by evaluating the number of outpatient department consultations and operative interventions before and after treatment with bisphosphonates in children with OI.

METHODS AND MATERIALS

Outpatient department consultation and operative intervention frequencies before and after treatment with bisphosphonates were registered. Children who had at least 2 years of medical records before treatment and at least 2 years after treatment were used in this study.

RESULTS

Of 118 children who were treated with bisphosphonates, 51 (23 boys and 28 girls) fulfilled the inclusion criteria. Statistical analysis revealed a significant decrease in outpatient department consultations (P < 0.000) and operative intervention (P < 0.003) before and after bisphosphonate treatment.

CONCLUSION

The pre-post design of our study shows a significant reduction of the number of outpatient department consultations and operative interventions in patients with OI after treatment with bisphosphonates.
