Summary

Progressive bone lengthening effectively treated hand deformities, achieving significant bone lengthening in both congenital and post-traumatic cases. While complications occurred, most were manageable, with a low rate of complete failure.

Area of Science:

  • Orthopedic Surgery
  • Hand Surgery
  • Regenerative Medicine

Background:

  • Progressive bone lengthening is a surgical technique used to correct limb length discrepancies and deformities.
  • Hand deformities, whether congenital or post-traumatic, can significantly impact a patient's quality of life and function.

Purpose of the Study:

  • To evaluate the efficacy and outcomes of progressive bone lengthening in treating hand deformities.
  • To compare results between congenital and post-traumatic cases.
  • To analyze complication rates and treatment duration.

Main Methods:

  • A retrospective study of 39 patients (47 hands) treated between 1989 and 1993.
  • Utilized the Hoffman distractor (34 cases) and Orthofix device (13 cases).
  • Assessed bone lengthening percentage, treatment duration, healing index, and complication rates.

Main Results:

  • Achieved 87% lengthening of hand skeleton and 47% of forearm bones in congenital cases; 51% in post-traumatic cases.
  • Average treatment duration was 6.7 months with a healing index of 1.7 months/cm.
  • Complication rate was 34%, including pain, delayed healing, and infections, but no pin removal was necessary.

Conclusions:

  • Progressive bone lengthening is a viable treatment for hand deformities, yielding substantial bone regeneration.
  • Congenital deformities showed higher lengthening percentages compared to post-traumatic cases.
  • Despite a notable complication rate, the overall success rate was high, with salvageable failures.
