[Three-step sequential method for limb skin and soft tissue defect combined with bone or tendon exposed wound]

Area of Science:

• Reconstructive surgery
• Tissue engineering
• Wound healing

Background:

• Limb skin soft tissue defects with exposed bone or tendon pose significant reconstructive challenges.
• Traditional flap repair may not always be suitable or desired by patients.

Purpose of the Study:

• To evaluate the clinical efficacy of a three-step sequential method using VSD technology, artificial dermis, and autograft for treating limb soft tissue defects with exposed bone or tendon.
• To assess wound recovery, graft survival, and aesthetic outcomes.

Main Methods:

• A cohort of 18 patients with limb skin soft tissue defects and exposed bone or tendon underwent a three-step sequential treatment.
• The method involved VSD technology, artificial dermis coverage, and subsequent autografting.
• Patients were followed up for wound healing and graft take.

Main Results:

• All treated wounds showed effective recovery of deep bone and tendon tissues.
• The artificial dermis demonstrated successful survival, leading to tough, well-shaped healed wounds.
• Autograft survival was good, with satisfactory cosmetic results including flat appearance and good skin color match.

Conclusions:

• The three-step sequential method is a viable and effective treatment for limb soft tissue defects with exposed bone or tendon, especially for patients who decline flap repair.
• This technique offers advantages of simple operation, low surgical risk, and minimally invasive characteristics.
