Area of Science:

  • Orthopedic surgery
  • Traumatology
  • Biomaterials engineering

Context:

  • Phalangeal fractures and osteoarticular infections present significant management challenges, often leading to deformity and stiffness.
  • External fixation is a recognized treatment modality for these complex injuries.
  • Existing external fixators can be complex in design and application.

Purpose:

  • To introduce and evaluate a new, inexpensive, and simple digital external fixator technique for phalangeal injuries.
  • To assess the stability and functional outcomes of this novel fixation method.
  • To report complications associated with the technique.

Summary:

  • A prospective study evaluated 24 patients with phalangeal fractures or infections treated with a new digital external fixator utilizing a mini-Hoffman apparatus and original materials.
