Nylon versus polydioxanone in the correction of rectus diastasis

Area of Science:

• Plastic Surgery
• Surgical Materials Science

Background:

• Rectus diastasis correction often involves sutures, with nylon and polydioxanone being common choices.
• Absorbable sutures like polydioxanone offer advantages in thin patients but may be less efficient against strong forces.

Purpose of the Study:

• To compare the efficacy of nylon versus polydioxanone sutures for rectus diastasis correction during abdominoplasty.
• To evaluate the long-term maintenance of correction using computed tomography (CT) scans.

Main Methods:

• A comparative study involving two groups (10 patients each) undergoing abdominoplasty with rectus diastasis repair.
• Control group used 2-0 nylon; experimental group used 0-polydioxanone for anterior aponeurosis plication.
• Abdominal wall tension was measured with a dynamometer; rectus diastasis width was assessed via CT scans preoperatively, intraoperatively, and at 3 weeks and 6 months postoperatively.

Main Results:

• Both suture groups demonstrated similar abdominal wall tension.
• Complete correction of rectus diastasis was achieved and maintained in both groups at 3 weeks and 6 months postoperatively, as verified by CT scans.
• Preoperative and intraoperative measurements showed no significant statistical difference in diastasis width, with minor variations at the inferior level.

Conclusions:

• Both 2-0 nylon and 0-polydioxanone are effective for rectus diastasis correction, with sustained results at 6 months.
• Computed tomography (CT) scanning is a reliable tool for assessing rectus diastasis and abdominal wall musculature.
