Tenotomy Scissors: Uses, Design, Types & Surgical Importance

 

Tenotomy scissors are specialized surgical instruments used primarily in delicate procedures involving the cutting of soft tissues, tendons, and fascia. Known for their precision and smooth cutting action, these scissors are essential tools in orthopedic surgery, plastic surgery, ophthalmology, podiatry, and various minimally invasive procedures.


What Are Tenotomy Scissors?

Tenotomy scissors are fine, sharp surgical scissors designed for performing tenotomy—the cutting or release of tendons to relieve tension or correct deformities. Their slim, lightweight structure and sharp tips make them ideal for working in small, confined, or sensitive anatomical areas.

Unlike regular surgical scissors, tenotomy scissors provide better maneuverability, finer control, and cleaner dissection, ensuring minimal trauma to surrounding tissues.


Key Features of Tenotomy Scissors

1. Fine, Narrow Blades

The slender blades allow surgeons to cut with high accuracy, especially in delicate procedures.

2. Blunt or Sharp Tips

Available in:

  • Blunt/Blunt – for safe dissection around vital structures

  • Sharp/Sharp – for precise cutting of small tendons or soft tissues

  • Blunt/Sharp – for versatile use

3. Straight or Curved Design

  • Straight scissors provide control for superficial cuts

  • Curved scissors enhance visibility and access during deeper or more complex dissections

4. High-Quality Stainless Steel

Surgical-grade steel ensures:

  • Corrosion resistance

  • Long-lasting sharpness

  • Autoclavability

  • Smooth cutting performance

5. Spring-like Tension

Provides seamless opening and closing, enhancing precision during surgery.


Types of Tenotomy Scissors

Several variations exist based on the surgical requirement:

1. Stevens Tenotomy Scissors

The most commonly used type—fine, curved, or straight blades ideal for ophthalmic and plastic surgeries.

2. Littler Tenotomy Scissors

Feature longer handles and delicate blades, used often in hand surgeries and reconstructive procedures.

3. Strabismus Tenotomy Scissors

Designed for eye surgeries, particularly for muscle adjustments in strabismus correction.

4. Dean or Baby Tenotomy Scissors

Small and extremely precise; used for pediatric or micro-surgical applications.


Common Surgical Uses of Tenotomy Scissors

Tenotomy scissors are versatile and widely used in:

1. Orthopedic Procedures

  • Tendon release

  • Correction of contractures

  • Foot deformity surgeries (e.g., clubfoot)

2. Plastic and Reconstructive Surgery

  • Skin flap elevation

  • Soft tissue dissection

  • Cosmetic procedures requiring precision

3. Ophthalmic Surgery

Used in delicate extraocular muscle procedures.

4. Podiatry

  • Plantar fascia release

  • Tendon adjustments in foot surgeries

5. ENT and General Surgery

For dissecting small tissue planes and performing fine cuts.


Advantages of Tenotomy Scissors

  • Highly precise cutting action

  • Minimal tissue trauma

  • Ideal for confined or sensitive areas

  • Lightweight and easy to handle

  • Versatile for various surgical specialties

  • Durable and easy to sterilize


Maintenance & Care

To ensure long instrument life and safety:

  • Clean immediately after use to prevent residue buildup

  • Ultrasonic cleaning recommended

  • Sterilize properly through autoclaving

  • Avoid dropping or bending the fine blades

  • Regularly check alignment and sharpness

Proper maintenance ensures consistent performance in delicate procedures.


Conclusion

Tenotomy scissors are indispensable instruments in modern surgical practice. Their fine blades, ergonomic design, and high precision make them ideal for delicate tissue and tendon procedures across multiple medical specialties. Whether in orthopedics, ophthalmology, podiatry, or plastic surgery, tenotomy scissors play a critical role in achieving surgical accuracy, reducing trauma, and promoting better patient outcomes.
