Soft Tissue Reconstruction Strategy of Spontaneous Calcaneal Fracture in a Patient with Diabetic Penetrating Foot Ulcer

Abstract

Background: Spontaneous pathologic fractures of the calcaneum in diabetic patients are rarely described in the literature. The pathologic fractures following osteomyelitis represent a possibly limb-threatening condition and if associated with a concomitant calcaneal ulcer, they present defiance for the surgeon and furthermore an outstandingly challenging condition to handle. Methods: A 61-year-old diabetic female patient on insulin therapy has been treated for a penetrating foot ulcer. In sequence the following procedures were carried out: Negative pressure wound therapy with instillation and dwell time (NPWTi-d), Negative Pressure Wound Therapy (NPWT), arterial percutaneous angioplasty (PTA), calcanectomy and temporary arthrodesis, application of Dermal Regeneration Template (DRT) and transplantation of microfractured autologous adipose graft (LIPOGEMS®), treatment of residual dehiscence with physical cold plasma (kINPen®MED). Results: The patient completely healed within 20 months and was able to walk without further aids. Conclusion: The authors point to the promptness within the treatment of pathologic calcaneal fractures, whether throughout the usage of technical devices targeting the reduction of the bacterial load and stimulation of healthy tissue, like in NPWTi-d and kINPen®MED. The use of a dermal regeneration template followed by skin grafting enriched with autologous microfractured adipose tissue (LIPOGEMS®), therefore represents today the most advanced regenerative surgical procedures.
