Intended Use

Indications for interlocking intramedullary nails include simple long bone fractures; severely comminuted, spiral, large oblique and segmental fractures; nonunions and malunions; polytrauma and multiple fractures; prophylactic nailing of impending pathologic fractures; reconstruction, following tumor resection and grafting; supracondylar fractures; bone lengthening and shortening. Interlocking intramedullary nails are indicated for fixation of fractures that occur in and between the proximal and distal third of the long bones being treated. In addition to the indications for interlocking intramedullary nails, devices that contain holes/slots proximally to accept screws that thread into the femoral head for compression and rotational stability are indicated for the following: subtrochanteric fractures with lesser trochanteric involvement; ipsilateral femoral shaft/neck fractures; and intertrochanteric fractures. The Smith & Nephew, Inc. TriGen Adolescent TAN is for single use only.

Device Story

TriGen Adolescent TAN is an intramedullary nail system used for orthopedic fracture fixation. Device is implanted surgically by a physician to stabilize long bone fractures, including femoral fractures requiring compression and rotational stability via proximal screws. System provides mechanical support to bone segments during healing. Device is for single use only.

Clinical Evidence

Bench testing only. Mechanical test data demonstrated the device is equivalent to currently marketed devices and capable of withstanding expected in vivo loading without failure.

Technological Characteristics

Intramedullary fixation rod; metallic construction; single-use; design includes proximal holes/slots for screws to provide compression and rotational stability.

Indications for Use

Indicated for patients with simple, comminuted, spiral, oblique, or segmental long bone fractures; nonunions; malunions; polytrauma; impending pathologic fractures; tumor resection/grafting; supracondylar fractures; and bone lengthening/shortening. Also indicated for subtrochanteric fractures with lesser trochanteric involvement, ipsilateral femoral shaft/neck fractures, and intertrochanteric fractures.

Regulatory Classification

Identification

An intramedullary fixation rod is a device intended to be implanted that consists of a rod made of alloys such as cobalt-chromium-molybdenum and stainless steel. It is inserted into the medullary (bone marrow) canal of long bones for the fixation of fractures.
