Orthopedic Plate Implants Surgical Techniques

🦴 ORTHOPEDIC PLATE IMPLANTS

🔧 DETAILED SURGICAL TECHNIQUE

Plate osteosynthesis is used for fracture stabilization, deformity correction, and reconstruction, providing rigid or biological fixation depending on technique.

1. 📋 Preoperative Planning

Clinical Evaluation

• Assess:

  • Fracture type (simple, comminuted, intra-articular)

  • Soft tissue condition

  • Neurovascular status

Imaging

• X-ray (AP & lateral)

• CT scan (complex/intra-articular fractures)

Planning Considerations

• Plate type:

  • Dynamic Compression Plate (DCP)

  • Locking Compression Plate (LCP)

  • Reconstruction plate

  • Buttress plate

• Screw type:

  • Cortical screws

  • Cancellous screws

  • Locking screws

👉 Plan plate length, screw number, and positioning.

2. 🛏️ Patient Positioning & Setup

• Position depends on fracture site:

  • Supine / lateral / prone

• Ensure:

  • Adequate exposure

  • C-arm access

• Sterile draping

• Prophylactic antibiotics

3. 🔪 Surgical Exposure

Steps:

1. Incision along anatomical planes

2. Gentle soft tissue dissection

3. Preserve:

   • Blood supply

   • Periosteum (when possible)

Techniques:

• Open reduction (ORIF)

• Minimally invasive plate osteosynthesis (MIPO)

4. 📍 Fracture Reduction

Methods:

• Manual reduction

• Reduction clamps / forceps

• Temporary K-wire fixation

Goals:

• Restore:

  • Alignment

  • Length

  • Rotation

  • Articular congruity (if joint involved)

👉 Confirm under fluoroscopy.

5. 🧱 Plate Selection & Preparation

Steps:

1. Choose appropriate plate length

2. Contour plate (if non-locking)

3. Position plate:

   • On tension side of bone

   • Bridging comminuted zone (if needed)

6. 🪛 Plate Fixation Techniques

A. Compression Plating (DCP Principle)

Steps:

1. Drill eccentric hole

2. Insert screw in dynamic hole

3. Tighten to create compression across fracture

Indications:

• Simple transverse/oblique fractures

B. Neutralization Plating

Steps:

1. Reduce fracture with lag screw

2. Apply plate to protect fixation

C. Bridge Plating (Biological Fixation)

Steps:

1. Span fracture zone without disturbing fragments

2. Fix plate proximally and distally

3. Avoid direct manipulation of fracture

👉 Preserves blood supply and promotes healing.

D. Locking Plate Technique (LCP)

Steps:

1. Position plate without excessive contouring

2. Insert locking screws:

   • Fixed-angle construct

3. Do not rely on plate-to-bone compression

Advantages:

• Better fixation in osteoporotic bone

• Angular stability

E. Buttress Plating

Steps:

1. Position plate to support fracture fragment

2. Prevent collapse (e.g., tibial plateau)

7. 🔩 Screw Insertion Principles

Steps:

1. Drill hole using guide

2. Measure depth

3. Tap (if required)

4. Insert screw

5. Tighten securely

Key Points:

• Bicortical purchase preferred

• Avoid over-tightening

• Use correct screw length

8. ⚖️ Intraoperative Assessment

Check:

• Fracture alignment

• Plate positioning

• Screw placement

Tools:

• Fluoroscopy (C-arm)

9. 🧼 Wound Closure

• Irrigation

• Hemostasis

• Layered closure

• Sterile dressing

10. 🏥 Postoperative Management

Immediate Care

• Pain control

• Limb elevation

• Antibiotics

Rehabilitation

• Early mobilization

• Gradual weight-bearing

11. ⚠️ Complications & Prevention

Complication Prevention

Infection

Sterile technique

Implant failure

Proper plate selection

Non-union

Adequate stability

Screw loosening

Correct insertion

Soft tissue irritation

Proper plate positioning

12. 🔓 Implant Removal (if required)

Steps:

1. Reopen incision

2. Remove screws

3. Remove plate

4. Irrigate and close

13. ✅ Key Surgical Principles

• Respect fracture biology

• Achieve stable fixation

• Use appropriate technique (compression vs bridge)

• Minimize soft tissue damage

• Ensure correct implant selection

🌟 Advantages of Plate Fixation

• Precise anatomical reduction

• Strong fixation

• Versatility across fracture types

• Suitable for complex fractures
