   • A drill guide is used to mark the location for the anchor points on the tibia.

3. Drilling Pilot Holes:

   • Insert a guide pin at the prepared tibial surface where the suture disk will be placed. The guide pin should be drilled perpendicular to the bone surface.

   • Drill pilot holes at the designated locations using the appropriate-sized drill bit. The depth of the pilot holes should be adequate to allow the suture disk to be securely seated.

4. Insertion of the Suture Disk:

   • Thread the sutures attached to the soft tissue (e.g., tendon or ligament) through the holes in the suture disk implant.

   • With the sutures pre-threaded, insert the suture disk into the drilled pilot holes. A mallet or gentle taps can be used to seat the disk flush with the tibial surface.

   • Ensure that the suture disk is securely anchored in the bone.

5. Tensioning and Fixation of Sutures:

   • Once the suture disk is implanted, tension the sutures to pull the soft tissue (tendon/ligament) firmly against the tibia.

   • Tie secure knots with the sutures to fix the tissue in place. These knots may be reinforced with additional sutures depending on the tissue quality and stability required.

   • Trim any excess suture ends after securing the knots.

6. Checking Stability:

   • After the soft tissue is secured to the tibia, check the stability of the repair by gently moving the limb through its range of motion. Ensure that the tissue remains well-fixed and that there is no undue movement at the repair site.

   • If needed, reinforce the fixation with additional sutures or an augmenting device.

7. Closure:

   • Irrigate the wound with sterile saline to remove any bone debris or tissue remnants.

   • Close the fascia with interrupted sutures, ensuring that there is no tension on the suture line.

   • The subcutaneous tissues are closed in layers, followed by skin closure with either sutures or staples.

8. Postoperative Care:

   • Apply a sterile dressing and a compressive bandage to the surgical site.

   • The limb is typically immobilized with a brace or cast, depending on the specific procedure and surgeon preference.

   • Postoperative rehabilitation begins with a gradual increase in weight-bearing and range of motion exercises under the supervision of a physical therapist.

Potential Complications

• Infection at the surgical site.

• Failure of fixation or loosening of the suture disk.

• Re-tearing of the repaired tissue.

• Irritation or pain at the implant site.

Postoperative Rehabilitation

• Phase 1 (0-2 weeks): Immobilization with non-weight-bearing. Focus on controlling swelling and pain.

• Phase 2 (2-6 weeks): Gradual weight-bearing with a brace, passive range of motion exercises.

• Phase 3 (6-12 weeks): Active range of motion, strengthening exercises, and progressive weight-bearing.

• Phase 4 (12+ weeks): Functional exercises, balance training, and return to sports or normal activities as appropriate.

Conclusion

The Tibia Suture Disk Implant is a valuable tool in orthopedic surgery, allowing for secure fixation of soft tissues to the tibia. Proper surgical technique and careful postoperative management are essential to ensure the success of the procedure and prevent complications.

The Orthopedic Loop Button Implant is typically used in ligament reconstruction surgeries, such as Anterior Cruciate Ligament (ACL) reconstruction. The procedure involves the use of a looped suture, often made from a high-strength material like polyethylene, threaded through a titanium or stainless steel button. This implant helps secure the graft into bone tunnels created in the knee joint. Below is a detailed surgical technique:

Preoperative Considerations

• Patient Positioning: The patient is positioned supine on the operating table with the affected knee placed in a leg holder. The non-affected leg should be well-padded to avoid pressure injuries.

• Anesthesia: General or regional anesthesia, depending on the surgeon’s and patient’s preference.

• Surgical Prep: Prepare the entire leg, draping it to allow for full manipulation of the knee joint during the surgery.

Step-by-Step Surgical Technique

1. Diagnostic Arthroscopy:

   • Insert the arthroscope through a standard anterolateral portal. Perform a thorough diagnostic arthroscopy to evaluate the joint and confirm the need for ligament reconstruction.

   • If any meniscal or cartilage injuries are present, address them as necessary.

2. Harvesting the Graft:

   • Autograft: Common graft options include hamstring tendons, patellar tendon, or quadriceps tendon.

   • Allograft: Alternatively, a pre-prepared allograft can be used.

   • Prepare the graft on a back table by whipping the ends with sutures, ensuring that it fits snugly into the bone tunnels.

3. Preparation of Bone Tunnels:

   • Drill a tunnel in the tibia and femur, corresponding to the graft size. Typically, the femoral tunnel is drilled through the anteromedial portal for anatomic placement of the graft.

   • Ensure accurate tunnel placement using fluoroscopy or arthroscopic landmarks to avoid complications like tunnel malposition.

4. Button Preparation and Loading:

   • Loop Button: The looped suture is threaded through the button. The size of the loop should match the graft and tunnel length.

   • Button Loading: Pass the prepared graft through the loop, and secure it by pulling on the looped suture, ensuring the graft sits securely against the button.

5. Femoral Tunnel Placement:

   • Insert a guidewire through the femoral tunnel. Ream the tunnel to the desired diameter.

   • Use the suture shuttle technique to pull the loop button through the femoral tunnel until it exits on the lateral side of the femur. Once the button exits, confirm its position via fluoroscopy or direct palpation.

6. Button Deployment and Locking:

   • Pull the loop button until it engages against the cortical surface of the femur.

   • Apply tension to the graft by pulling on the sutures, ensuring that the button sits securely against the bone.

   • The graft should be tensioned under arthroscopic visualization, with the knee placed in full extension to simulate physiological tension on the ligament.

7. Tibial Fixation:

   • Tension the graft from the tibial side, ensuring proper alignment and tension of the reconstructed ligament.

   • Fix the graft in the tibial tunnel using a fixation device such as an interference screw, post-and-washer system, or additional sutures.

8. Final Assessment:

   • Perform a final arthroscopic assessment of the knee joint. Check for proper tension and positioning of the graft.

   • Perform range of motion testing to ensure the stability of the knee joint.

9. Closure:

   • Close the arthroscopic portals with sutures or steri-strips.

   • Apply a sterile dressing and an appropriate knee brace to immobilize the joint.

Postoperative Protocol

• Weight Bearing: Partial weight bearing is allowed, depending on the graft type and surgeon preference.

• Rehabilitation: Initiate a structured rehabilitation program, focusing on restoring range of motion, strength, and proprioception.

• Follow-up: Regular follow-up appointments to monitor graft integration, tunnel healing, and knee function.

Potential Complications

• Tunnel misalignment leading to graft failure

• Infection or deep vein thrombosis (DVT)

• Graft rupture or elongation

• Hardware failure

This technique provides stability and facilitates early rehabilitation in ligament reconstruction surgeries.

Surgical Technique for Orthopedic Low Profile Cancellous Screw Implant

• Implant Selection: Choose the appropriate size and length of the low-profile cancellous screw based on bone quality and the specific anatomical location. Confirm compatibility with the patient's anatomy.

2. Positioning and Anesthesia

• Patient Positioning: Position the patient appropriately for the surgical site, ensuring proper access to the fractured area. This may involve supine, lateral, or prone positioning depending on the fracture location.

• Anesthesia: General or regional anesthesia based on the patient’s condition and surgeon’s preference.

3. Incision and Exposure

• Incision: Make a precise incision over the fracture site or the area requiring fixation. The incision length will vary based on the location and size of the fracture.

• Soft Tissue Dissection: Carefully dissect through the soft tissues to expose the underlying bone. Avoid excessive soft tissue damage to preserve vascularity and reduce the risk of infection.

4. Fracture Reduction

• Reduction of the Fracture: Using manual manipulation or the assistance of reduction tools (clamps, bone holders), reduce the fracture fragments to their anatomical position. Confirm the reduction with fluoroscopy or X-ray imaging.

• Provisional Fixation: Use temporary K-wires or reduction clamps to hold the fragments in place before definitive fixation.

5. Drill and Tap

• Drilling: Select the appropriate drill bit for the screw size. Drill a pilot hole through the cortex and into the cancellous bone at the desired trajectory. The drill hole should match the core diameter of the screw.

• Depth Measurement: Measure the depth of the drilled hole using a depth gauge to determine the correct screw length.

• Tapping (optional): For dense cancellous bone, tapping may be necessary. Use a tap that corresponds to the screw thread profile. This will create the threads in the bone for easier screw insertion.

6. Screw Insertion

• Screw Placement: Insert the low-profile cancellous screw through the pre-drilled and tapped hole. Start by hand and then use a screwdriver or powered driver for full insertion. The screw should be advanced until it provides adequate compression across the fracture site but should not be overtightened.

• Low-Profile Feature: Ensure the screw head sits flush with or below the bone surface to minimize soft tissue irritation and prominence. Confirm the positioning under fluoroscopy.

7. Final Fixation and Confirmation

• Additional Fixation (if needed): If more than one screw is required, repeat the drilling, tapping, and screw insertion process. Alternatively, supplementary fixation (plates, wires, etc.) may be used based on the fracture type.

• Imaging Confirmation: Use intraoperative fluoroscopy or X-ray to confirm proper alignment, reduction, and screw placement. Adjust as needed.

8. Closure

• Wound Irrigation: Irrigate the wound thoroughly with saline to reduce the risk of infection.

• Soft Tissue Closure: Close the soft tissues in layers using absorbable sutures for the deep layers and non-absorbable sutures or staples for the skin.

• Dressing: Apply sterile dressings to protect the surgical site.

9. Postoperative Care

• Immobilization: Depending on the fracture site and patient’s condition, immobilization using a cast, splint, or brace may be necessary.

• Rehabilitation: Early motion is encouraged in most cases, but weight-bearing should be restricted based on the surgeon’s recommendation.

• Follow-up: Regular follow-up appointments with imaging to monitor healing and detect any complications, such as screw loosening or migration.

10. Potential Complications

• Infection: Preventative antibiotics and sterile technique help minimize the risk.

• Screw Loosening or Backing Out: Monitor for signs of instability and intervene if necessary.

• Nonunion or Malunion: Ensure proper alignment and fixation to reduce the risk of poor bone healing.

• Soft Tissue Irritation: The low-profile nature of the screw head reduces this risk, but patients should be monitored for any discomfort.

11. Conclusion

The low-profile cancellous screw is an effective method for fracture fixation, particularly in areas where soft tissue irritation is a concern. Proper surgical technique, including accurate drilling, tapping, and screw insertion, is critical for successful outcomes. Postoperative care and monitoring ensure the best chance for complete healing.

A spiked washer is used in orthopedic surgeries to enhance fixation, particularly in cases where screws are insufficient to provide adequate stabilization of bones, grafts, or other implants. Here’s a detailed surgical technique for the implantation of a spiked washer in orthopedic procedures, such as in the treatment of ligament or tendon repairs, or in cases of bone fractures.

Surgical Technique for Orthopedic Spiked Washer Implantation

Indications:

• Ligament or tendon repair: Spiked washers may be used to enhance the pull-out strength of tendon or ligament repair by securing sutures or screws.

• Fracture fixation: Used in cases where screws alone may not provide sufficient stability for bone fragments, especially in osteoporotic bone.

• Bone graft fixation: To augment fixation in cases of poor bone quality.

Preoperative Planning:

1. Imaging: Obtain X-rays, CT scans, or MRI of the affected area to understand the anatomy, bone quality, and the extent of the fracture or soft tissue damage.

2. Instrumentation: Ensure the availability of appropriate orthopedic instruments such as drills, screws, spiked washers, plate systems, and fixation devices.

3. Washer Selection: Select the appropriate size and shape of the spiked washer based on the fracture pattern and bone quality. Washers may be circular, elliptical, or designed to conform to specific anatomical contours.

Procedure:

Step 1: Patient Positioning and Anesthesia

• Positioning: Place the patient in a suitable position based on the location of the injury. For example, supine for lower extremities or lateral decubitus for shoulder procedures.

• Anesthesia: Administer general or regional anesthesia depending on the case and patient's health status.

Step 2: Incision and Exposure

• Incision: Make a skin incision over the affected area according to the fracture or ligamentous injury.

• Exposure: Carefully dissect through the soft tissue to expose the bone. Retraction of soft tissues should be done gently to avoid damage to nerves and vessels.

• Fracture site preparation: Clean the fracture site or damaged tissue area thoroughly. Use a rongeur or curette to debride the fracture or repair site, removing any loose or necrotic tissue.

Step 3: Drill Hole Preparation

• Fracture reduction: If applicable, reduce the fracture using reduction clamps or temporary Kirschner wires (K-wires) for provisional stabilization.

• Drilling: Identify the location where the spiked washer will be placed. Typically, a hole is drilled through the cortex of the bone using a power drill. The hole diameter should match the size of the screw that will be inserted through the spiked washer.

• Tapping: Depending on bone density, tap the drill hole if necessary to create threads for the screw, particularly in dense bone.

Step 4: Spiked Washer Placement

• Positioning the Washer: Place the spiked washer over the drill hole. Ensure the spikes of the washer are pointing towards the bone to provide firm grip when the screw is tightened.

• Screw Insertion: Insert a bone screw (cortical or cancellous depending on the type of bone) through the washer and into the drilled hole.

  • Tighten the screw gradually. As the screw advances, the spiked washer will press into the bone, providing additional surface area for fixation and preventing the screw head from pulling through the bone.

  • Ensure that the washer remains flush with the bone surface, with no soft tissue interposition.

Step 5: Fixation Verification

• Stability Check: Test the stability of the fixation by applying gentle manual stress to the bone or tendon.

  • If the spiked washer is used in ligament or tendon repair, ensure the tension is adequate for the repair.

  • For fracture fixation, verify that the bone fragments are secure and well-aligned.

Step 6: Wound Closure

• Soft Tissue Repair: After confirming adequate fixation, close the soft tissues layer by layer.

  • Reattach the periosteum if disrupted, followed by muscle, fascia, and subcutaneous tissue.

  • Close the skin using sutures or staples.

Step 7: Postoperative Care

• Immobilization: Depending on the type of procedure, place the patient in a cast, brace, or splint to protect the repair.

• Imaging: Obtain postoperative X-rays or CT scans to confirm the proper placement of the spiked washer and screw.

• Rehabilitation: Develop a rehabilitation protocol tailored to the specific surgery, which may include physical therapy and gradual weight-bearing as permitted by the fixation strength and fracture healing.

Complications and Considerations:

• Infection: Adhere to aseptic techniques to prevent infection at the surgical site.

• Failure of Fixation: Ensure proper placement of the washer and screws to avoid fixation failure. In osteoporotic bone, additional fixation strategies (such as multiple screws or washers) may be necessary.

• Soft Tissue Impingement: Take care to avoid soft tissue interposition between the spiked washer and the bone to prevent irritation or necrosis.

Conclusion:

Spiked washers are an effective adjunct in orthopedic fixation, especially in challenging cases involving poor bone quality or high tension on ligaments/tendons. Proper surgical technique, including careful selection of instrumentation and verification of fixation, can ensure optimal outcomes for the patient.

The surgical technique for an arthroscopic U-Fiber implant, typically used in rotator cuff repair, involves several key steps:

1. Preoperative Planning

• Patient Evaluation: Thoroughly assess the patient's medical history, physical examination, and imaging studies (X-rays, MRI) to evaluate the rotator cuff tear and determine if this technique is appropriate.

• Implant Selection: Choose the appropriate size and type of U-Fiber implant based on the tear size, location, and patient anatomy.

2. Surgical Setup

• Patient Positioning: The patient is typically placed in a lateral decubitus position (on their side) or a beach chair position (semi-sitting).

• Anesthesia: General anesthesia is commonly used.

• Portal Placement: Establish standard arthroscopic portals (posterior, anterior, lateral) for visualization and instrument access.

3. Arthroscopic Evaluation

• Joint Examination: Systematically inspect the glenohumeral joint for any additional pathology.

• Tear Assessment: Evaluate the rotator cuff tear's size, location, and tissue quality.

• Tendon Mobilization: Release any adhesions or scar tissue to ensure adequate tendon mobility.

4. Implant Insertion

• Bone Preparation: Prepare the bone at the insertion site on the humerus using a burr to create a bleeding bony bed.

• Implant Placement: Insert the U-Fiber implant through a cannula and into the bone socket. The implant's design allows for secure fixation in the bone.

• Suture Passage: Pass the sutures attached to the implant through the rotator cuff tendon using a suture passer.

5. Tendon Repair

• Suture Management: Retrieve the sutures through an accessory portal and tie them securely to reapproximate the torn tendon to the bone.

• Tension Adjustment: Adjust the suture tension to achieve optimal tendon-to-bone contact and avoid over-tensioning.

• Knot Tying: Tie arthroscopic knots to secure the sutures and complete the repair.

6. Closure and Postoperative Care

• Wound Closure: Close the portal incisions with sutures or skin staples.

• Dressing: Apply a sterile dressing to the shoulder.

• Postoperative Instructions: Provide detailed instructions on pain management, activity restrictions, and rehabilitation protocols.

Additional Considerations:

• Double-Row Repair: In some cases, a double-row repair technique may be used for larger or more complex tears. This involves placing a second row of U-Fiber implants to provide additional fixation and strength.

• Augmentation: For patients with poor tissue quality, a patch or other augmentation material may be used to reinforce the repair.
