The Giannini endo-orthotic implant effectively treats pediatric flatfoot, significantly reducing pain and improving foot structure. This surgical technique offers good clinical and radiographic outcomes for children with flatfoot deformity.

Area of Science:

  • Orthopedic surgery
  • Pediatric orthopedics
  • Foot and ankle surgery

Background:

  • Pediatric flatfoot deformity is a common condition affecting children.
  • Arthroereisis is a surgical option for correcting severe flatfoot.
  • The Giannini endo-orthotic implant is a specific device used in arthroereisis.

Purpose of the Study:

  • To evaluate the clinical and radiographic outcomes of arthroereisis using the Giannini endo-orthotic implant.
  • To assess the effectiveness of this technique in treating pediatric flatfoot deformity.

Main Methods:

  • Retrospective evaluation of 37 patients (65 feet) treated with the Giannini endo-orthotic implant.
  • Follow-up averaged 26.5 months, with assessment of pain, function, sports participation, and radiographic measurements.

  • Radiographic angles were measured at multiple intervals post-surgery.

    • Main Results:

    • Postoperative pain decreased from 60% to 6%.
    • 59% of feet had normal postoperative footprints; 41% had first-degree flatfoot.
    • Significant correction was observed in the talar-first metatarsal angle (99%) and calcaneal pitch (36%).
    • No postoperative deterioration in radiographic angles was noted.
    • Complications occurred in 10.7% of patients, primarily postoperative pain.

    Conclusions:

    • The Giannini endo-orthotic implant arthroereisis technique yields good clinical and radiographic results for pediatric flatfoot.
    • This method respects the foot's anatomical structure.
    • The procedure demonstrates a favorable outcome profile with minimal complications.
