Arterialization of plantar venous system via vein graft: A novel technique for reconstruction of heel pad degloving injuries

BACKGROUND

Patients with heel pad degloving injury frequently develop ischemic necrosis of the area, necessitating soft-tissue reconstruction surgery. We have developed a technique for arterialization of the plantar venous system via vein graft (APV) as the primary revascularization treatment. The objective of this study was to clarify both the utility of APV for the preservation of degloved heel pads and the impact of this preservation on clinical outcomes.

METHODS

Ten consecutive cases of degloving injury with devascularized heel pad were treated at a single trauma center from 2008 to 2018. Five cases underwent APV and five underwent conventional primary suture (PS) as the initial treatment. We evaluated the course according to the frequency of heel pad preservation, additional intervention after heel pad necrosis, post-operative complications, and outcomes using the Foot and Ankle Disability Index score (FADI) at the time of last follow-up.

RESULTS

Among the five cases that underwent APV, the heel pad was preserved in three cases and flap surgery was required in two cases. All cases that underwent PS developed necrosis of the heel pad, requiring skin graft in one case and flap surgery in four. One skin graft case and one free flap case after PS developed plantar ulcers. The three cases with preserved heel pads exhibited higher FADI than the seven cases that developed necrosis.

CONCLUSION

APV showed a relatively high frequency of heel pad preservation, which otherwise was uniformly lacking. Functional outcomes were improved in cases with preserved heel pad compared to those that developed necrosis and underwent additional tissue reconstruction.

Management of Heel Pad Degloving Injury After Severe Foot Crush Injury: A Case Report Study

Crush injuries of the foot and ankle are uncommon and they have a poor prognosis leading to some form of disability. Degloving injuries of the heel and foot after crush injuries are rare and very challenging to manage due to the need for reconstruction of both osseous and soft tissue architecture. We present a salvage strategy for an open injury to the foot with extensive soft tissue detachment from the plantar and dorsal surface. A 30-year-old man was transferred to the Emergency Department from a neighboring hospital with a crush injury to the foot that had resulted in a degloving injury of the heel pad, after a motorcycle accident. The patient had a 20 cm circumferential wound that was extending from dorsal to the plantar surface along with rupture of the extensor digitorum longus (EDL) tendons and transection of the superficial peroneal nerve. There was an extensive detachment of soft tissues from the deep fascia and bones, whereas the posterior tibial artery was intact. In radiographic imaging, a small inferior avulsion fracture of the calcaneus along with fractures of the cuneiform bones was revealed. The initial management involved thorough surgical debridement, removal of necrotic tissues, repair of EDL tendons and fracture stabilization. Negative-pressure wound therapy was also applied for six weeks. Subsequently, a split-thickness skin graft was used to cover the skin defect. Six months after injury, the patient had a normal range of motion, intact sensation over the sole and could ambulate independently. Although the majority of heel pad degloving injuries have a poor prognosis, there are positive prognostic factors as presented in the current case for a satisfying functional final outcome, which include vascular intergrity, fracture stabilization, soft-tissue reconstruction with negative pressure wound therapy, and application of skin grafts.

A salvage strategy for heel pad degloving injury

Case:

A 50-year-old female experienced a crush injury to the foot resulting in open degloving of her heel pad. This study details a surgical strategy to achieve healing and limb salvage.

Conclusion:

Heel pad injuries with degloving are difficult to salvage and have a poor prognosis. Amputation is often the only therapeutic option, unless part of the blood supply to the heel pad is intact, rendering limb salvage a possibility.
