Endo Button Introduction, Uses, Sizes and Advantage.

Endo Button

The Endo Button is extensively used in orthopedic surgery, particularly in the repair and rebuilding of the knee’s anterior cruciate ligament (ACL). It is a non-traditional method of connecting grafts to bone during ACL restoration treatments.

The Endo Button is a fixation device that secures and reliably attaches the graft to the bone. It comprises of a small metallic button, usually made of titanium, that is affixed to the graft’s looped or folded end. The device is intended to be implanted into a bone tunnel drilled near the original ACL attachment locations in the femur (thigh bone) or tibia (shin bone).

During the surgery, the graft is placed in the knee joint and the looped or folded end is passed through the bone tunnel. The Endo Button is then put on the bone’s outer surface, and the looped end of the graft is dragged back through the tunnel until the button rests securely against the bone surface.

The Endo Button works by utilising the mechanical properties of the bone and the design of the button. As the graft’s looped end is tightened, the button self-locks onto the bone’s outer surface, securely locking the transplant in place. This method provides robust attachment while allowing the graft to mend and integrate into the bone biologically.

Endo Button Advantages and Uses in Orthopedic Surgery

Orthopedic operations, particularly those involving ligament restoration, have made substantial progress in recent years. The Endo Button, a small yet strong implant that has revolutionised graft attachment techniques, is one such innovation. The Endo Button has unquestionably had a substantial impact in orthopedic surgery, notably in ligament repair techniques. This little device has improved surgical outcomes and patient experiences due to its strong fixation, stress distribution, and less invasive approach. As orthopaedic procedures advance, the Endo Button demonstrates the power of innovation in expanding medical treatments and improving patient quality of life.

The benefits of using the Endo Button in ACL reconstruction include:

Improved Fixation Strength:
The EndoButton has various advantages over conventional fastening techniques like screws or staples. It first offers a solid and reliable attachment, lowering the possibility of graft failure or slippage. Because of the way the device is made, there is more contact between the graft and the bone tunnel, which aids in stability and healing.

Stress Reduction and Better Healing:
The button-shaped design of the Endo Button also helps to better healing outcomes. It decreases stress concentration on the graft by dispersing pressures over a greater area. This distribution reduces the possibility of excessive stress on any particular portion of the graft, facilitating better healing and lowering the risk of re-injury.

Technique with Minimal Invasion:
Orthopedic operations frequently try to reduce tissue injury and encourage faster healing. The Endo Button contributes to these objectives by providing for a minimally invasive surgical procedure. Patients may suffer less discomfort, edoema, and scarring as a result of fewer incisions and less disruption to the surrounding tissues.

Widespread Use and Flexibility:
The Endo Button has come to be extensively accepted and used in orthopedic procedures. Its versatility extends beyond ACL restoration to include other ligament repair operations such as PCL reconstruction and multiligament knee surgeries. The versatility of the technology makes it a vital tool for orthopedic surgeons all over the world.

Patient Advantages and Better Outcomes:
Ultimately, the Endo Button’s advantages translate into better patient outcomes. The implant can help patients restore strength, movement, and function more effectively by increasing stability and supporting optimal healing. The lower risk of complications and re-injury may result in shorter recovery durations, allowing patients to resume their busy lifestyles sooner.

The usage of the Endo Button is not without potential hazards and considerations, much like any surgical treatment or medical equipment. These could consist of surgical risks, hardware-related issues, graft failure, or infections. Before deciding on the best surgical approach and fixation method, orthopaedic surgeons must carefully assess each patient’s condition and go over the advantages and potential hazards.

In summary the Endo Button is a common fixation tool in ACL repair surgery, to sum up. It offers various advantages over conventional fixation techniques, secure graft attachment, and healing promotion. Its application has helped patients restore stability, function, and an active lifestyle by resulting in better results and successful ACL surgeries.

Endo Button 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 Endo Button.

Warnings and Precautionary for Endo Button

Before using Endo Button, 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.

Button is made from medical grade materials and are designed, constructed and produced with utmost care. These quality Button 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  Button 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 Button, 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 Endo Button.
  • Mechanical failure of the implant, including bending, loosening or breakage.
  • Migration of implant resulting in injury.

Preoperative Planning for Endo Button

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 Endo Button 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.

Endo Button 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 Button.
  • 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.

Endo Button Warnings

  • Endo Button 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. Button removal should be followed by adequate post-operative management to avoid refracture.
