Modified tension band technique for patella fractures

Area of Science:

• Orthopedic surgery
• Trauma surgery
• Surgical techniques

Background:

• Tension band wire technique is standard for patella fracture fixation.
• Standard technique with two Kirschner wires can lead to prominent hardware.
• Challenges exist in capturing the figure-of-eight wire configuration with the standard method.

Purpose of the Study:

• To describe a modified tension band wire technique for patella fracture fixation.
• To address complications associated with the standard technique, such as prominent hardware.
• To present a case series evaluating the modified technique's efficacy.

Main Methods:

• A modified surgical technique using four Kirschner wires for patella fracture fixation is detailed.
• Each Kirschner wire is bent and impacted to improve fixation and reduce prominence.
• The technique was reviewed alongside a case series.

Main Results:

• The modified technique with four Kirschner wires effectively avoids prominent hardware issues.
• Improved impaction of wires was achieved, enhancing fixation stability.
• The technique simplifies the transition to a figure-of-eight wire construct.

Conclusions:

• The modified four-Kirschner wire technique offers an improvement over the standard method for patella fracture fixation.
• This technique enhances patient comfort by reducing hardware prominence.
• It provides a reliable and effective alternative for managing patella fractures.
