Device Facts

• Record ID: K984209
• Device Name: STAINLESS STEEL TAPER FOREMAN NAIL CANNULATED SCREW, STAINLESS STEEL CANNULATED SCREW, SHORT THREAD, STAINLESS STEEL PED
• Applicant: Biomet, Inc.
• Product Code: HWC · Orthopedic
• Decision Date: Feb 3, 1999
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 888.3040
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

The cannulated screws may be used for fixation of long bone fractures and for bone reconstruction (i.e. fresh fractures, osteotomy, revision procedure where other treatments or devices have failed, arthrodesis, and in conjunction with other fixation hardware). These cannulated screws are not to be used for spinal application or Carpal Tunnel Sydrome.

Device Story

Cannulated screws provide internal bone fixation; used for long bone fractures and reconstruction. Device consists of stainless steel or titanium alloy screws; diameters 3.5mm-8.0mm. Implanted by surgeons in clinical settings to stabilize bone segments; facilitates healing via compression or rigid fixation. Output is mechanical stabilization of bone. Benefits include fracture reduction and support for bone fusion. Risks include nonunion, implant breakage, loosening, or metal sensitivity.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

Materials: Stainless steel and titanium alloy. Design: Cannulated screw geometry; diameters 3.5mm to 8.0mm. Function: Mechanical bone fixation fastener. Energy source: None (passive implant).

Indications for Use

Indicated for fixation of long bone fractures and bone reconstruction, including fresh fractures, osteotomy, revision procedures, and arthrodesis. Contraindicated for spinal application and Carpal Tunnel Syndrome.

Regulatory Classification

Identification

A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system.

Device Classification: Class II

Device Product Code: 87 HWC-screw, fixation, bone

Intended Use: The cannulated screws may be used for fixation of long bone fractures and for bone reconstruction (i.e. fresh fractures, osteotomy, revision procedure where other treatments or devices have failed, arthrodesis, and in conjunction with other fixation hardware). These cannulated screws are not to be used for spinal application or Carpal Tunnel Sydrome.

Device Description: Various styles of stainless steel and titanium alloy cannulated screws. Screw diameters range from 3.5mm to 8.0mm and 6.5mm to 8.0mm, respectively.

Potential Risks: The risks associated with these devices are the same as with any metallic internal fixation device. These include but are not limited to the following:

-Delayed or nonunion which may lead to breakage of the implant

-Bending or fracture of the implant

-Loosening or migration of the implant

- -Metal sensitivity, or allergic reaction to a foreign body
-Limb shortening or decrease in bone density due to compression of the fracture or bone resorption

-Pain, discomfort, or abnormal sensations due to the presence of the device
