Summary

Lower limb lengthening in Turner dwarfism can achieve significant length gains, improving limb and leg-trunk proportions. While complications occurred in all cases, patient satisfaction remained high, suggesting it

Area of Science:

  • Orthopedics
  • Genetics
  • Endocrinology

Background:

  • Turner dwarfism is a rare genetic condition often associated with short stature.
  • Lower limb lengthening is a surgical option for limb length discrepancies.
  • The efficacy and safety of limb lengthening in Turner dwarfism are not well-established.

Purpose of the Study:

  • To review outcomes of lower limb lengthening in patients with Turner dwarfism.
  • To evaluate the effectiveness and complication rates of limb lengthening in this population.
  • To explore the feasibility of limb lengthening as a treatment for short stature in Turner dwarfism.

Main Methods:

  • Retrospective review of 6 patients with Turner dwarfism undergoing lower limb lengthening.
  • Ilizarov method for tibial lengthening and gradual elongation nail for femoral lengthening.

  • Minimum 2-year follow-up, assessing length gain, healing index, and complications.

    • Main Results:

    • Average tibial and femoral length increase of 6.2 cm and 6.0 cm, respectively.
    • Significant improvement in tibia-to-femur ratio (0.68 to 0.81) and leg-trunk ratio (0.88 to 0.99).
    • 100% complication rate per bone; common issues included pin site infections, nonunion, and contractures; osteopenia was noted in nonunion cases.

    Conclusions:

    • Lower limb lengthening can effectively increase leg length and improve proportions in Turner dwarfism.
    • Despite a high complication rate, patients reported satisfaction with the aesthetic and functional outcomes.
    • Careful management in specialist centers is crucial, addressing osteopenia associated with estrogen deficiency to mitigate consolidation issues.
