Guide Wire Cannulated Screw Specification, Uses, Sizes and Surgical Techniques.

Guide Wire Cannulated Screw

A Guide Wire Cannulated Screw is a thin, flexible wire inserted into the body to guide cannulated screws during surgery. Our Guide Wire is made from finest quality of SS 316L material to ensure highest quality. Cannulated Screw Guide Wire Specifications are:

1.2 mm Diameter and 230 mm Length for 4 mm Cannulated Screw
2 mm Diameter and 230 mm Length for 6.5 mm Cannulated Screw

The main advantage of cannulated screws is that they can be inserted over a guide wire. The diameter of the Guide Wire Cannulated Screw is much smaller than the cannulated screw and can be more accurately placed using fluoroscopy in the operating room. In addition, given its small diameter, the Guide Wire Cannulated Screw can be reinserted several times if necessary for accurate placement without excessive damage to bone.

Guide Wire Cannulated Screw Contraindications

Contraindications may be qualified or total, and need to be taken into consideration when evaluating the prognosis in each case. Alternative management techniques may need to be considered under the following conditions:

Acute or chronic infections, either local or systemic.
Local or systemic accurate or chronic inflammation.
Serve muscular, nervous or vascular disease endangering the affected area.
Defective bone structures, which would impede adequate anchoring of the implant.
All associated diseases which could endanger the function and success of the implant.

Warnings and Precautionary for Guide Wire Cannulated Screw

Before using Guide Wire Cannulated Screw, the surgeon and ancillary staff should study the safety information in these instructions, as well as any product-specific information in the product description, surgical procedures and/or brochures.

Guide Wire Cannulated Screw are made from surgical grade 316L Stainless Steel and are designed, constructed and produced with utmost care. These quality Guide Wires assure best working results provided they are used in the proper manner. Therefore, the following instructions for use and safety recommendations must be observed.

Improper use of this instrument can lead to damage to the tissue, premature wear, destruction of the instruments and injury to the operator, patients or other persons.

It is vital for the operating surgeon to take an active role in the medical management of their patients. The surgeon should thoroughly understand all aspects of the surgical procedure and instruments including their limitations. Care in appropriate selection and proper use of surgical instruments is the responsibility of the surgeon and the surgical team. Adequate surgical training should be completed before use of Guide Wires.

Factors which could impair the success of the operation:

Allergies to implanted materials.
Localized bone tumours.
Osteoporosis or osteomalacia.
System disease and metabolic disturbances.
Alcohol and drug abuse.
Physical activities involving excessive shocks, whereby the implant is exposed to blows and/or excessive loading.
Patients who are mentally unable to understand and comply with the doctor’s instructions.
Poor general health.

Possible Adverse Effects

The following adverse effects are the most common resulting from implantation:

Loosening of the implant, which may result from cyclic loading of the fixation site and/or tissue reaction of the implant.
Early and late infection.
Further bone fracture resulting from unusual stress or weakened bone substance.
Temporary or chronic neural damage resulting from pressure or hematomata.
Wound hematomas and delayed wound healing.
Vascular disease including venal thrombosis, pulmonary embolism and cardiac arrest.
Heterotopic ossification.
Pain and discomfort due to presence of the implant.
Mechanical failure of the implant, including bending, loosening or breakage.
Migration of implant resulting in injury.

Preoperative Planning for Guide Wire Cannulated Screw

The operating planning is carried out following a thorough clinical evaluation of the patient, Also, x-rays must be taken to allow a clear indication of the bony anatomy and associated deformities. At the time of the operation, the corresponding implantation instruments in addition to a complete set of implants must be available.

The clinician should discuss with the patient the possible risks and complications associated with the use of Guide Wire Cannulated Screw. It is important to determine pre-operatively whether the patient is allergic to any of the implant materials. Also, the patient needs to be informed that the performance of the device cannot be guaranteed as complications can affect the life expectancy of the device.
