The Role of Negative Pressure Wound Therapy in Temporizing Traumatic Wounds before Lower Limb Soft Tissue Reconstruction: A Systematic Review

Background

In practice, there is often a delay from initial debridement and temporary fixation to definitive soft tissue coverage of traumatic leg wounds. Without clear evidence, conservative negative pressure wound therapy (NPWT) is increasingly used to temporize these wounds. This systematic review summarizes and synthesizes the literature on using NPWT to temporize traumatic leg wounds before surgery in adult surgical patients.

Methods

A comprehensive search of Medline, Embase, and Cochrane Library was performed from inception until July 2022, inclusively. Two independent reviewers performed screening, data extraction, and risk of bias assessment. Primary English studies, including adult patients (≥16 years old) with a fracture below the knee up to and including the ankle that received NPWT to temporize wounds before definitive soft tissue reconstruction with a flap and/or graft, were included.

Results

Thirty-four studies, including 804 patients who received NPWT, were included. The partial/total flap loss rate was 6.95% (n = 9 studies), the infection rate was 19.5% (n = 25 studies), the nonunion rate was 18% (n = 15 studies), the delayed union rate was 9.31% (n = 3 studies), and the amputation rate was 15.4% (n = 6 studies). The mean late stay was 43.1 days (n = 9 studies), and the follow-up length was 23.7 months (n = 9 studies). The mean time to wound healing was 5.63 months (n = 2 studies), and the time to soft tissue coverage was 40.8 days (n = 12 studies). The mean time to achieve bone union was 7.26 months (n = 6 studies).

Conclusion

NPWT can be used to temporize traumatic wounds while awaiting soft tissue reconstruction.

A Novel Limb Salvage Technique of External Fixation Protection of Lower Extremity Plastic Reconstructions with Immediate Postoperative Ambulation (Bibbo Flap and Frame Technique)

Non-weight bearing is mandatory after soft tissue reconstructions of the weight-bearing and the high-pressure areas in the lower extremity. The most common method of patient mobilization after surgical reconstruction of chronic foot and ankle wounds has been to place patients non-weight bearing with crutches, walkers, or a wheelchair. Often patients are older, have more complex medical comorbidities, are deconditioned, and simply cannot comply with the prescribed weight-bearing status with these methods, which leads to deconditioning, depression, or noncompliance. Noncompliance quickly leads to failure of the reconstructive effort and the serious threat of limb loss.

Reverse sural flap with bifocal Ilizarov technique for tibial osteomyelitis with bone and soft tissue defects

Tibial osteomyelitis, in association with bone loss and a soft tissue defect, poses a significant reconstructive challenge, especially in high-risk patients. We describe a case of methicillin-resistant Staphylococcus aureus tibial osteomyelitis with intercalary bone loss successfully managed with bifocal Ilizarov compression osteogenesis at the bone resection site and proximal distraction osteogenesis, accompanied by a reverse sural fasciocutaneous flap performed with a delayed technique. When free tissue transfer is not a reconstructive option owing to medical comorbidities or patient refusal, the reverse sural flap combined with bifocal Ilizarov compression and distraction osteogenesis can provide a reconstructive option to achieve limb salvage for these challenging cases.
