Titanium Mesh Cage Introduction

The introduction of the Titanium Mesh Cage in spinal surgery has opened up a variety of applications that are realizable as a result of the versatility of the implant.

Since their debut in 1986, Titanium Mesh Cages have been extensively employed for spine restoration. It is not necessary to harvest huge structural bone grafts because these cages can be employed as structural devices containing autologous local bone or iliac crest bone transplant.

Titanium Mesh Cage Sizes

Titanium of the highest quality, which has exceptional biocompatibility, strength, and durability, is typically used to make Titanium Mesh Cage. Because titanium is radiolucent and does not interfere with X-rays or other imaging methods, the fusion site can be clearly seen after surgery.

Titanium Mesh Cage are available in various diameters and lengths.
Diameters: 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 22mm, 24mm and 26mm
Lengths: 60mm, 70mm, 80mm, 90mm and 100mm

Titanium Mesh Cage Uses

In spinal fusion surgery, the worn-out or injured disc that lies between two vertebrae is removed, and the empty disc space is filled with a bone transplant. The titanium mesh cage, acting as a support structure or spacer, is subsequently put into the disc space. It maintains the disc space, encourages fusion of the neighbouring vertebrae, and aids in restoring the spine’s natural height and alignment.

Typically porous or perforated, the titanium mesh cage allows bone transplant material to be put inside. As a result, the fusion process is facilitated by encouraging bone growth through and around the cage. As new bone tissue grows around the cage, the cage eventually fuses with the surrounding bone, giving the fused spinal segment support and stability.

Titanium Mesh Cage Advantage

The principal advantage of the Titanium Mesh Cage is a reduction in donor site morbidity. Because it can provide immediate load-bearing support to the anterior column, a structural bone graft is not necessary. Instead, a less invasive autograft harvest can be done to acquire cancellous bone to fill the cage and pack the disc space around the cage. For a single-level anterior cervical discectomy and fusion, a small cortical window can be made on top of the anterior iliac crest through which cancellous autograft can be obtained without disrupting the tables of the ilium. In most individuals, a 1-inch incision is sufficient to harvest this type of graft. The iliac crest donor site then can be reconstituted by packing the defect with cancellous allograft or demineralized bone matrix. With this approach, donor site pain and complications have been minimal in the authors’ experience. For reconstructions after corpectomy, cages can be filled with the resected vertebral body bone that is generated locally. Additional cancellous autograft can be harvested, if necessary, via the cortical window technique described above. Alternatively, bone graft extenders such as demineralized bone matrix can be used.

Titanium Mesh Cage 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 Titanium Mesh Cage .

Warnings and Precautionary for Titanium Mesh Cage

Before using Titanium Mesh Cage, 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.

Cage is made from medical grade materials and are designed, constructed and produced with utmost care. These quality cages 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 Mesh Cage 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 implants.

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 cage, 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 Titanium Mesh Cage.
Mechanical failure of the implant, including bending, loosening or breakage.
Migration of implant resulting in injury.

Preoperative Planning for Titanium Mesh Cage

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 size of Titanium Mesh Cage must be available.

The clinician should discuss with the patient the possible risks and complications associated with the use of implants. 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.

Titanium Mesh Cage Precautions

Confirm functionality of instruments and check for wear during reprocessing. Replace worn or damaged instruments prior to use.
It is recommended to use the instruments identified for this cage.
Handle devices with care and dispose worn bone cutting instruments in a sharps container.
Always irrigate and apply suction for removal of debris potentially generated during implantation or removal.

Titanium Mesh Cage Warnings

Titanium Mesh Cage can break during use (when subjected to excessive forces). While the surgeon must make the final decision on removal of the broken part based on associated risk in doing so, we recommend that whenever possible and practical for the individual patient, the broken part should be removed. Be aware that implants are not as strong as native bone. Implants subjected to substantial loads may fail.
Instruments, screws and cut plates may have sharp edges or moving joints that may pinch or tear user’s glove or skin.
Take care to remove all fragments that are not fixated during the surgery.
While the surgeon must make the final decision on implant removal, we recommend that whenever possible and practical for the individual patient, fixation devices should be removed once their service as an aid to healing is accomplished. Mesh Cage removal should be followed by adequate post-operative management to avoid refracture.

Titanium Mesh Cage General Adverse Events

As with all major surgical procedures, risks, side effects and adverse events can occur. While many possible reactions may occur, some of the most common include: Problems resulting from anesthesia and patient positioning (e.g. nausea, vomiting, dental injuries, neurological impairments, etc.), thrombosis, embolism, infection, nerve and/or tooth root damage or injury of other critical structures including blood vessels, excessive bleeding, damage to soft tissues incl. swelling, abnormal scar formation, functional impairment of the musculoskeletal system, pain, discomfort or abnormal sensation due to the presence of the device, allergy or hypersensitivity reactions, side effects associated with hardware prominence, loosening, bending, or breakage of the device, mal-union, non-union or delayed union which may lead to breakage of the Titanium Mesh Cage, reoperation.
