Intended Use

The Stryker® External Fixation System is intended to stabilize and provide treatment for fractures of the maxillofacial area, including severe open mandibular fractures, highly comminuted closed fractures, nonunions and delayed unions (especially associated with infection), fractures associated with infections, turnor resections, facial deformity corrections, gunshot wounds, pan facial fractures, burn maintenance, and bone grafting defects.

Device Story

Stryker® External Fixation System provides mechanical stabilization for maxillofacial bone fractures and defects. Device consists of metallic components used to fixate bone segments; applied by surgeons in clinical settings. System functions as a rigid frame to maintain bone alignment during healing or reconstruction. Benefits include stabilization of complex fractures, nonunions, and post-surgical defects. Device is purely mechanical; no electronic or software components.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

Metallic bone fixation system; mechanical assembly; non-electronic; non-software; dimensions and materials consistent with predicate external fixation systems.

Indications for Use

Indicated for patients requiring stabilization and treatment of maxillofacial fractures, including severe open mandibular fractures, highly comminuted closed fractures, nonunions, delayed unions, infection-associated fractures, tumor resections, facial deformity corrections, gunshot wounds, pan facial fractures, burn maintenance, and bone grafting defects.

Regulatory Classification

Identification
