Scalpel vs. Electrocautery: Which Blade Reigns Supreme for Skin Incisions?

Jordan Keane in Health & Wellness July 2025 • 4 min read.

"A head-to-head comparison of scalpel and electrocautery techniques in orthopedic surgery reveals surprising insights into healing, speed, and safety."

For generations, the scalpel has been the go-to instrument for making skin incisions. However, electrocautery, a more recent innovation, has emerged as a potential alternative. While some surgeons worry that electrocautery might increase infection risk or impair healing, recent research suggests it could offer benefits such as reduced blood loss and faster incision times.

A key question remains: is electrocautery a safe and effective substitute for the scalpel in skin incisions during orthopedic surgeries? One study directly compared the two methods to find out.

This article breaks down the findings of a prospective study conducted at a tertiary care center, where researchers compared electrocautery incisions with conventional scalpel incisions in patients undergoing orthopedic surgeries with internal implants. We'll explore the impact on healing, complications, and speed, providing a clearer picture of which blade might be best.

Electrocautery vs. Scalpel: A Close Examination of Skin Incision Techniques

Scalpel vs. Electrocautery blades clashing

The study, conducted at the Department of Orthopaedics, BPKIHS, Dharan, Nepal, focused on patients with closed forearm fractures requiring surgery. Each patient's incision was strategically divided: the proximal half was opened using a traditional steel scalpel, while the distal half was opened with an electrocautery blade. This innovative approach allowed for a direct, side-by-side comparison within the same patient.

Researchers meticulously compared the two halves of each incision, assessing them on the day of surgery, as well as on days 2 and 14, and again at 6 weeks and 3 months post-operation. Here's what they looked at:

Incision time
Postoperative wound complication rates
Color and viability of the skin
Presence of charring
Dermal peeling
Scar tenderness
Hypertrophy or keloid formation
Wound dehiscence

The electrocautery unit was set to a specific cutting mode, using a 390-kHz sinusoid waveform at a power of 5 W. Surgeons were careful to only allow the tip of the electrocautery blade to contact the skin and avoided touching the skin edges to minimize potential thermal damage.

The Verdict: Is Electrocautery Ready to Replace the Scalpel?

The study revealed that forearm skin incisions made with electrocautery were significantly faster than those made with a scalpel (p<0.05). However, postoperative wound complication rates did not differ significantly between the two groups (p>0.05).

The researchers concluded that there is no significant difference in the healing of skin incisions made by electrocautery compared to those made by scalpel in orthopedic surgeries using internal implants. This suggests that electrocautery can be a safe and efficient alternative for skin incisions in these procedures.

While the study provides valuable insights, it's important to note that it focused specifically on closed forearm fractures. Further research may be needed to determine the applicability of these findings to other types of orthopedic surgeries and patient populations. However, for surgeons seeking a faster incision method without compromising safety, electrocautery appears to be a viable option.

Everything You Need To Know

What is the difference between a scalpel and electrocautery?

The study investigated the use of both a **scalpel** and **electrocautery** for skin incisions during orthopedic surgery. A **scalpel** is a traditional surgical instrument with a sharp blade, while **electrocautery** uses heat generated by an electric current to cut tissue and seal blood vessels. The study aimed to compare these two methods, focusing on factors such as incision time, wound healing, and complication rates.

What surgical procedure was used to compare electrocautery to the scalpel?

The study compared **electrocautery** and **scalpel** incisions in patients undergoing orthopedic surgeries for closed forearm fractures. The researchers made a side-by-side comparison within each patient, using a **scalpel** for the proximal half of the incision and **electrocautery** for the distal half. This allowed for a direct comparison of healing, complications, and speed.

What were the main findings when comparing electrocautery and scalpel for skin incisions?

One of the main findings was that skin incisions made with **electrocautery** were significantly faster than those made with a **scalpel**. However, there was no significant difference in postoperative wound complication rates between the two methods. These findings suggest that **electrocautery** could potentially offer time-saving benefits in orthopedic surgery without compromising patient safety in terms of wound healing.

What specific factors were assessed to compare the healing and outcomes of electrocautery versus a scalpel?

The study assessed several factors to compare **electrocautery** and **scalpel**, including incision time, wound complication rates, skin color and viability, the presence of charring, dermal peeling, scar tenderness, hypertrophy or keloid formation, and wound dehiscence. These factors were assessed on the day of surgery, at day 2 and 14, and again at 6 weeks and 3 months post-operation, providing a comprehensive evaluation of the healing process and any potential adverse effects.

How was the electrocautery device used in the study, and how did it compare to the scalpel?

The **electrocautery** unit in the study was set to a specific cutting mode, using a 390-kHz sinusoid waveform at a power of 5 W. Surgeons ensured that only the tip of the **electrocautery** blade contacted the skin, avoiding contact with the skin edges to minimize thermal damage. The **scalpel** was used according to standard surgical practice.
