Summary

Bioabsorbable poly-L-lactide rods offer a simple and effective alternative for digital replantation osteosynthesis. This technique avoids protruding hardware and simplifies the procedure, leading to successful bone fusion.

Area of Science:

  • Orthopedic Surgery
  • Biomaterials Science

Background:

  • Traditional Kirschner wire fixation for digital replantation osteosynthesis presents challenges, including hardware protrusion, restricted mobilization, and the need for removal.
  • Exploring alternative fixation methods is crucial for improving patient outcomes and simplifying surgical procedures in digital replantation.

Observation:

  • A novel technique utilizing bioabsorbable poly-L-lactide (PLLA) rods as intramedullary nails for digital osteosynthesis was implemented starting in February 1995.
  • This method was applied to 15 arthrodeses (involving distal interphalangeal, proximal interphalangeal, and thumb interphalangeal joints) and 11 phalangeal diaphysis fractures.

Findings:

  • The PLLA rod technique demonstrated technical simplicity and eliminated the issue of protruding hardware requiring removal.

  • Clinical and radiographic evidence of bone fusion was achieved in all patients, with an average fusion time of 8.4 weeks.
  • No cases of nonunion or infection were reported; bone resorption occurred in only one patient.

    • Implications:

    • Bioabsorbable PLLA rod fixation presents a safe, effective, and straightforward method for digital replantation osteosynthesis.
    • This technique enhances patient comfort by avoiding hardware removal and potentially improves functional recovery.
    • The study supports the use of PLLA rods as a viable alternative in orthopedic trauma and reconstructive surgery.
