A retrospective case series study evaluating the use of synthetic dermal matrix for complex wounds: the Hong Kong experience.

BACKGROUND

Partial-thickness skin grafts (PTSG) are the conventional method for definite wound closure in orthopaedics; however, synthetic dermal matrix have emerged as an alternative for complex wounds, particularly when vital structures, like tendon and bone, are exposed.

OBJECTIVE

This case series evaluates the clinical outcomes, cost implications, and granulation capacity of synthetic dermal matrix compared to PTSG using case-based observations and literature comparisons.

METHODS

Seven patients with complex wounds treated with synthetic dermal matrix at a public hospital in Hong Kong between December 2023 and May 2024 were followed until complete wound healing. Outcomes included healing time, 30-day wound size reduction, matrix integration after delamination, hospitalization duration, and vital structure coverage.

RESULTS

Synthetic dermal matrix showed successful granulation in all cases with variable healing times (51-205 days). Granulation over bone, tendon, and joint was observed in 71.4 % of patients. No readmissions or hematoma formation occurred.

CONCLUSION

Synthetic dermal matrix is a safe and effective method for managing wounds with exposed vital structures and shows potential cost benefits over traditional PTSG. Further studies with larger samples are needed.
