Distraction osteogenesis effectively corrected congenital hand deformities in 12 digits across nine young patients. This bone lengthening technique proved reliable for osseous defects, with minimal angular deformities and no infections.

Area of Science:

  • Orthopedic Surgery
  • Pediatric Hand Surgery
  • Regenerative Medicine

Background:

  • Congenital hand anomalies often present complex osseous defects.
  • Surgical correction is necessary to improve function and aesthetics.
  • Distraction osteogenesis offers a potential solution for bone lengthening.

Purpose of the Study:

  • To evaluate the efficacy of distraction osteogenesis in correcting congenital hand deformities.
  • To assess the safety and predictability of the procedure in pediatric patients.

Main Methods:

  • Distraction osteogenesis was applied to lengthen 12 bones in nine pediatric patients (ages 2.5-7 years).
  • The average distraction period was 31.1 days, achieving an average bone lengthening of 23.6 mm.
  • Regenerate bone remodeling was performed for angular deformities in 17% of cases.

Main Results:

  • Successful lengthening of 12 digits was achieved using distraction osteogenesis.
  • The average bone lengthening was 23.6 mm over an average of 31.1 days.
  • Angular deformities requiring remodeling occurred in 17% of patients; no infections were reported.

Conclusions:

  • Distraction osteogenesis is a reliable and predictable method for correcting osseous defects in congenital hand anomalies.
  • The technique facilitates bone lengthening with vascularized bone, offering a valuable treatment option.
  • This approach demonstrates a low complication rate, making it suitable for pediatric hand reconstruction.
