Barbed versus conventional suture in elective posterior spine surgery

Area of Science:

• Spinal Surgery
• Surgical Techniques
• Wound Healing

Background:

• Barbed sutures offer potential for reduced operating room time and costs.
• Conventional sutures are the standard for posterior spinal surgery wound closure.

Purpose of the Study:

• To evaluate the non-inferiority of barbed sutures compared to conventional methods for wound closure in posterior spinal surgery.
• To analyze the utility of barbed sutures in reducing operating room time and costs.

Main Methods:

• A cohort study comparing barbed (prospective) versus conventional sutures (retrospective) in elective posterior spinal surgery.
• Primary endpoint: wound healing complications or need for surgical revision.
• Secondary endpoints: postoperative stay, readmission rate, duration, and cost of wound closure.

Main Results:

• No significant difference in wound healing complications (dehiscence, seroma, superficial/deep infections) between barbed and conventional sutures.
• Barbed sutures significantly reduced wound closure duration (1.66 vs. 4.16 min/level, p<0.0001).
• Mean cost of wound closure was higher with barbed sutures (€43.23 vs. €22.67, p<0.0001), but re-intervention rates were similar.

Conclusions:

• Barbed sutures are effective for wound closure in posterior spinal procedures, significantly decreasing closure time.
• The wound healing process is not adversely affected by barbed sutures.
• The increased cost of barbed suture material is minimal compared to the gains in surgical efficiency.
