Summary

The Luhr Micro System offers effective rigid internal fixation for craniofacial bone repair. Its small, low-profile plates and screws provide adequate support for orbital reconstruction and craniofacial deformities.

Area of Science:

  • Craniofacial Surgery
  • Orthopedic Surgery
  • Neurosurgery

Background:

  • Rigid internal fixation using plates and screws is a standard treatment for midface, orbit, and cranial bone fractures and osteotomies.
  • The Luhr Micro System represents the latest generation of Luhr Systems, offering the smallest available hardware for rigid internal fixation.

Observation:

  • The Luhr Micro System features self-tapping screws (0.8 mm diameter, 2-8 mm length) and plates with an extremely flat profile.
  • The system has been utilized for closing osteotomies after orbital tumor resection, bony orbital reconstruction, and correcting congenital craniofacial deformities.

Findings:

  • The Micro System provides adequate bony fixation in the periorbital region due to minimal functional stress on orbital bones.
  • The flat profile of the plates ensures they are not visible through thin periorbital skin.

Implications:

  • The Luhr Micro System demonstrates superior performance compared to larger fixation systems, wire, or nonabsorbable sutures for periorbital bony fixation.
  • This system offers a less invasive and aesthetically superior option for complex craniofacial reconstructions.
