Silicone moulding for pressure sore debridement

Area of Science:

• Surgical Innovation
• Wound Debridement Techniques
• Pressure Sore Management

Background:

• Radical wound debridement is crucial for effective pressure sore treatment.
• Existing methods like methylene blue or hydrogen peroxide injections are insufficient for optimal surgical debridement.
• Ischial pressure sores present unique challenges in surgical management.

Purpose of the Study:

• To present an innovative modification of the pseudo-tumor technique using fluid silicone injection for pressure sore debridement.
• To evaluate the efficacy and safety of silicone molding in facilitating radical and sterile excision of pressure sores.
• To assess the technique's impact on complication and recurrence rates in paraplegic patients.

Main Methods:

• A modified pseudo-tumor technique involving fluid silicone injection into pressure sores.
• Vulcanization of silicone to create a precise mold of the pressure sore.
• Radical en bloc debridement guided by the silicone mold in 10 paraplegic patients with ischial pressure sores.
• Three-dimensional (3D) analysis of silicone prints to characterize sore morphology.

Main Results:

• Silicone molding facilitated radical en bloc debridement in all 10 patients.
• Complete resection without capsular lesions was achieved.
• No complications or recurrences were observed after a minimum follow-up of 2 years.
• 3D analysis revealed the characteristic pyramidal shape of ischial pressure sores.

Conclusions:

• Silicone molding is an effective and innovative technique for radical debridement of pressure sores.
• The method ensures complete resection and provides valuable pre-operative information for defect coverage.
• This technique offers a promising approach to improve surgical outcomes and reduce recurrence in pressure sore treatment.
