Bone Cement | Fillers Surgical Techniques

🦴 BONE CEMENT & BONE FILLERS

🔧 DETAILED SURGICAL TECHNIQUE GUIDE

Bone cement and fillers are used for:

• Implant fixation (arthroplasty)

• Void filling (trauma, tumor, cysts)

• Vertebral augmentation (spine procedures)

1. 📋 Preoperative Planning

Clinical Indications

• Joint replacement (hip/knee fixation)

• Bone defects (post-trauma or tumor curettage)

• Osteoporotic fractures (vertebroplasty/kyphoplasty)

Imaging

• X-ray

• CT / MRI (if required)

Material Selection

• Bone Cement (PMMA – Polymethylmethacrylate)

• Bone Fillers:

  • Calcium phosphate

  • Calcium sulfate

  • Hydroxyapatite

👉 Choose based on:

• Load-bearing requirement

• Resorbability

• Defect size

2. 🛏️ Patient Positioning & Setup

• Depends on procedure:

  • Supine (arthroplasty)

  • Prone (spine procedures)

• Ensure:

  • C-arm access (for vertebral procedures)

• Sterile preparation

3. 🧴 BONE CEMENT PREPARATION (PMMA)

Steps:

1. Open sterile cement kit

2. Mix powder + liquid monomer:

   • Hand mixing OR vacuum mixing

3. Monitor phases:

   • Mixing phase

   • Waiting phase

   • Working phase

   • Setting phase

👉 Timing is critical for optimal handling.

4. 🧱 APPLICATION TECHNIQUES

A. Cemented Arthroplasty (Hip/Knee)

Steps:

1. Prepare bone surface:

   • Clean and dry

2. Insert cement:

   • Using cement gun

3. Pressurize cement into bone

4. Insert implant:

   • Maintain position until cement sets

Key Points:

• Ensure uniform cement mantle

• Avoid air bubbles

B. Vertebroplasty / Kyphoplasty

Steps:

1. Insert needle into vertebral body

2. Prepare cement

3. Inject cement under fluoroscopy

4. Monitor for leakage

👉 Stop immediately if leakage occurs.

C. Bone Void Filling (Cysts / Tumors)

Steps:

1. Curettage of lesion

2. Irrigate cavity

3. Fill with:

   • Cement OR bone substitute

4. Allow setting

D. Bone Fillers (Biological Substitutes)

Steps:

1. Prepare defect

2. Mix filler (if required)

3. Insert into defect

4. Mold to shape

Key Points:

• Ensure good contact with host bone

• Avoid overpacking

5. ⚖️ Intraoperative Assessment

Check:

• Proper filling of defect

• Implant stability

• Cement distribution

Tools:

• Fluoroscopy (if required)

6. 🧼 Wound Closure

• Irrigation

• Remove excess cement

• Layered closure

• Dressing

7. 🏥 Postoperative Management

Immediate Care

• Pain management

• Monitor for complications

Mobilization

• Early weight-bearing (depends on fixation)

8. ⚠️ Complications & Prevention

Complication                                                          Prevention

Cement leakage                                                      Controlled injection

Thermal necrosis                                                     Proper cement volume

Implant loosening                                                    Good cement technique

Infection                                                                   Sterile handling

Embolism (rare)                                                       Careful pressurization

9. 🔓 Revision / Removal

Indications:

• Implant failure

• Infection

• Cement loosening

10. ✅ Key Surgical Principles

• Proper timing of cement use

• Adequate bone preparation

• Uniform cement distribution

• Avoid over-pressurization

• Ensure implant stability

🌟 Advantages of Bone Cement & Fillers

• Immediate fixation

• Enhanced implant stability

• Versatile applications

• Biocompatibility (fillers)

• Bone regeneration support (bio-fillers)
