Summary

AO/ASIF Principles of Tibial Nailing

Expert Tibial Nail Indications

Preoperative Planning and Sizing

Opening the Tibia: Patient Positioning and Setup

Opening the Tibia: Fracture Reduction

Opening the Tibia: Nail Size Confirmation

Confirming Nail Diameter and Length

Use radiographic ruler on AP/lateral X-rays to precisely measure the medullary canal for nail selection.

Opening the Tibia: Surgical Approach

Opening the Tibia: Entry Point Identification

Determining Optimal Nail Entry Point

Entry point location is critical for preventing fragment displacement in proximal and distal fractures.

Opening the Tibia: Guide Wire Insertion

Inserting the Guide Wire Correctly

Secure guide wire, mark insertion point, and insert 8-10 cm, confirming position radiographically.

Opening the Tibia: Medullary Canal Preparation

Using Cutter for Canal Opening

Open medullary canal to 8-10 cm depth with cutter and protection sleeve, avoiding posterior cortex contact.

Opening the Tibia: Medullary Canal Preparation (continued)

Using Drill Bit for Canal Preparation

Prepare canal with drill bit and protection sleeve to 8-10 cm depth, ensuring no posterior cortex contact.

Using Awl for Canal Preparation

Open medullary canal with cannulated awl using a twisting motion to 8-10 cm depth, avoiding posterior cortex.

Opening the Tibia: Optional Reaming

Inserting the Tibial Nail: Instrument Assembly

Assembling Insertion Instruments

Connect insertion handle, connecting screw, and nail, ensuring correct orientation and secure attachment.

Inserting the Tibial Nail: Nail Insertion

Guiding Nail Insertion into the Canal

Insert nail into canal with twisting motion, hyper-flexing knee. Monitor passage and final position radiographically.

Inserting the Tibial Nail: Final Checks and Aids

Inserting the Tibial Nail: Proximal Position Check

Checking Proximal Nail Position

Attach aiming arm and guide wire to verify proximal nail placement and orientation using lateral imaging.

Inserting the Tibial Nail: Distal Position Check

Checking Distal Nail Position

Verify final nail position in both AP and lateral views. Ensure secure connection to the insertion handle.

Distal Locking Procedure: Overview and Technique

Performing Distal Locking

Select appropriate screws/bits. Lock distally first using backstroke technique for compression and stability.

Distal Locking Procedure: Alignment and Incision

Distal Locking Procedure: Drilling

Drilling for Distal Locking Screw Placement

Center drill bit tip in locking hole and drill through both cortices. Use tip for better control after near cortex perforation.

Distal Locking Procedure: Screw Length Measurement

Determining Correct Locking Screw Length

Measure screw length using a direct measuring device after drilling, considering compression needs.

Distal Locking Procedure: Screw Length Measurement (continued)

Distal Locking Procedure: Screw Insertion

Inserting Distal Locking Screws

Use screwdriver and holding sleeve to insert screws of correct length. Verify placement and repeat if necessary.

Proximal Locking Procedure: Instrument Selection

Selecting Proximal Locking Instruments

Choose appropriate screws, sleeves, trocars, and drill bits based on nail diameter and locking option (DYNAM, STAT 2, STAT 1).

Proximal Locking Procedure: Aiming Arm Mounting

Mounting the Aiming Arm

Attach aiming arm to insertion handle after confirming nail connection. Avoid applying undue force.

Proximal Locking Procedure: Trocar Insertion

Inserting the Trocar Combination

Assemble trocar, drill sleeve, and protection sleeve. Insert through aiming arm hole, make stab incision, and advance to bone.

Proximal Locking Procedure: Drilling and Measurement

Drilling and Measuring for Proximal Screws

Ensure drill sleeve is firm. Drill through cortices. Measure screw length from calibrated drill bit.

Proximal Locking Procedure: Screw Length Measurement

Proximal Locking Procedure: Screw Insertion

Inserting Proximal Locking Screws

Insert screws through protection sleeve using screwdriver. Verify length; tip should not protrude excessively.

Proximal Locking Procedure: Compression Locking

Proximal Locking Procedure: Compression Screw Insertion

Inserting the Compression Screw

Advance compression screw through connecting screw to reduce fracture gap, monitoring radiographically.

Proximal Locking Procedure: Monitoring and Static Locking

Inserting Static Locking Screws

Insert second proximal screw (Static 1) and remove compression screw. Optional cancellous bone screws can be added.

Proximal Locking Procedure: Oblique Technique

Oblique Proximal Locking Technique

Use leg extension and cancellous screws in oblique (OBLI 1, OBLI 2) and A/P holes for proximal fragment fixation.

Proximal Locking Procedure: Drilling Precautions

Proximal Locking Procedure: Tibial Head Fractures

Proximal Locking Procedure: Proximal Position Check

Proximal Locking Procedure: Alignment Verification

Proximal Locking Procedure: Alternative Locking

Proximal Locking Procedure: Cancellous Screw Drilling

Proximal Locking Procedure: Cancellous Screw Insertion

Inserting Cancellous Bone Locking Screws

Insert screws through protection sleeve using screwdriver. Verify screw length and avoid over-tightening.

Proximal Locking Procedure: Additional Screws

Inserting the End Cap

Inserting the End Cap: Threading Process

Implant Removal: Initial Steps

Implant Removal: Nail Extraction Preparation

Implant Removal: Nail Extraction

Extracting the Tibial Nail

Gently tap the nail out with a hammer or use an extraction screw with an air pulse system.

Implants: Locking Screws

Implants: Locking Screws (continued)
