TENS Nail
TENS Nail (Titanium Elastic Nail) are intended for fixation of diaphyseal fractures where the canal is narrow or flexibility of the implant is paramount.
TENS Nail also intended to treat metaphyseal and epiphyseal fractures, such as radial neck fractures, and is intended for fixation of small long bones, such as carpal and tarsal bones. In pediatric applications, the flexibility of the elastic nail allows it to be inserted at a point which avoids disruption of the bone growth plate.
Titanium Elastic Nail (TENS Nail) Features and Benefits:
Nail tip
Allows easy nail insertion and sliding along the medullary canal.
Height of the tip guarantees correct relation to the medullary cavity.
Facilitates nail manipulation for fracture reduction.
Nail diameters
Six nail diameters for all indications.
Available in titanium and stainless steel.
Titanium Elastic Nail (TENS Nail) Sizes
TENS Nail (Titanium Elastic Nail) are available in six diameters.
1.5 mm Dia, 440 mm Length
2 mm Dia, 440 mm Length
2.5 mm Dia, 440 mm Length
3 mm Dia, 440 mm Length
3.5 mm Dia, 440 mm Length
4 mm Dia, 440 mm Length
Measure the narrowest diameter of the medullary canal with a ruler. The proper nail diameter is no more than forty percent of the width of the canal.
The following guidelines for femoral nailing are sizes typically used for children of average stature and are dependent on patient anatomy:
Age 6-8, Nail Size 3 mm
Age 9-11, Nail Size 3.5 mm
Age 12-14, Nail Size 4 mm
Select two TENS Nail (Titanium Elastic Nail) of the same diameter so the opposing bending forces are equal, avoiding malalignment.
Ti alloy implants combine excellent mechanical stability with elastic properties.
Stainless steel implants for higher mechanical requirements.
Nail marking
Allows direct visual control of the alignment of the nail tip in the medullary canal reducing exposure to the image intensifier
TEN end caps
Two sizes of end caps to cover all nail diameters.
Sharp self-cutting thread for proper fixation in bone.
Provide additional axial stability in unstable situation.
Reduce the risk of soft-tissue irritation.
Facilitate implant removal.
Elastic stable intramedullary nailing (ESIN) with the Titanium Elastic Nail (TEN) or Stainless Steel Nail (STEN) is indicated for the management of diaphyseal and certain metaphyseal/ epiphyseal fractures of long bones in children and young adults.
As follows:
Diaphyseal and certain metaphyseal fractures of long bones.
Certain metaphyseal/-epiphyseal fractures, including but not limited to radial neck fractures.
Complex clavicular fractures (significant dislocation including shortening, “floating shoulder”).
Open fractures.
Threat of skin perforation at fracture ends.
Pathologic fractures.
Titanium Elastic Nail (TENS Nail) Indications in Adults
In adult patients, TEN is used for the osteosynthesis of clavicle, forearm and humerus fractures.
As follows:
Diaphyseal fractures of long bone fractures in upper extremity.
Clavicle shaft fractures.
TENS Nail (Titanium Elastic Nail) Contraindications
Contraindications may be qualified or total, and need to be taken into consideration when evaluating the prognosis in each case. The physician’s education, training and professional judgement must be relied upon to choose the most appropriate device and treatment. Conditions presenting an increased risk of failure include:
Any active or suspected latent infection or marked local inflammation in or about the affected area.
Compromised vascularity that would inhibit adequate blood supply to the fracture or the operative site.
Bone stock compromised by disease, infection or prior implantation that can not provide adequate support and/or fixation of the devices.
Material sensitivity, documented or suspected.
Obesity. An overweight or obese patient can produce loads on the implant that can lead to failure of the fixation of the device or to
failure of the device itself.Patients having inadequate tissue coverage over the operative site.
Implant utilization that would interfere with anatomical structures or physiological performance.
Any mental or neuromuscular disorder which would create an unacceptable risk of fixation failure or complications in postoperative care.
Other medical or surgical conditions which would preclude the potential benefit of surgery.
All associated diseases which could endanger the function and success of the TENS Nail (Titanium Elastic Nail).
