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.

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.
