Diabetic Foot Ulcers (DFU)
Prevalence: Affects 15-25% of diabetic patients
Diabetic foot ulcers remain the leading cause of non-traumatic lower limb amputation in developed nations. These wounds develop due to the complex interplay of neuropathy, peripheral vascular disease, and impaired immune response inherent to diabetes. Unlike acute wounds, DFUs often become chronic, persisting for months or years without appropriate intervention.
The underlying pathophysiology involves multiple factors: sensory neuropathy prevents patients from detecting injuries, motor neuropathy causes muscle atrophy and abnormal pressure distribution, and autonomic neuropathy impairs normal sweating and skin conditioning. Additionally, hyperglycemia impairs neutrophil function and collagen synthesis, while microvascular disease reduces oxygen and nutrient delivery to the wound bed.
How Sunspot's Kerecis Fish Skin Grafts Help: Fish skin provides a natural biologic scaffold containing omega-3 fatty acids that actively promote granulation tissue formation and epithelialization. Clinical evidence demonstrates superior closure rates with Kerecis compared to standard treatments.

Venous Leg Ulcers (VLU)
Prevalence: Most common chronic lower extremity wound
Venous leg ulcers result from chronic venous insufficiency, characterized by incompetent venous valves and impaired calf muscle pump function. This leads to venous hypertension, which causes capillary damage, tissue edema, and eventual ulceration. VLUs typically affect the medial aspect of the lower leg above the ankle and are notoriously difficult to heal, often requiring compression therapy as a foundational treatment.
The pathophysiology involves sustained venous pressure, leading to leukocyte extravasation, macrophage activation, and chronic inflammation. This inflammatory environment impairs normal healing progression and promotes a cycle of tissue degradation. While compression is essential, biological wound support accelerates healing in the context of optimized vascular management.
How Sunspot's Products Help: Kerecis fish skin grafts support granulation tissue formation and promote epithelialization within the inflammatory environment of VLUs. The biologic scaffold integrates with the wound bed, creating an optimal environment for tissue regeneration while compression therapy manages the underlying venous hemodynamics.

Pressure Ulcers (Bed Sores)
Stages: II, III, and IV requiring advanced intervention
Pressure ulcers develop from sustained mechanical pressure on tissue, primarily affecting immobile or partially immobile patients. The pathophysiology involves initial ischemic tissue injury from occlusion of capillary blood flow, followed by reperfusion injury when pressure is relieved. Stage II-IV ulcers require advanced biological intervention, particularly when underlying bone involvement or extensive tissue loss is present.
These wounds are particularly challenging because patients often have comorbidities affecting healing (diabetes, vascular disease, malnutrition, advanced age). The wound bed is typically contaminated with biofilm-forming bacteria, and compromised perfusion limits the effectiveness of systemic therapies. Local biologic intervention becomes critical to create an environment supporting tissue regeneration despite systemic limitations.
How Sunspot's Products Help: Kerecis biologic dressings provide essential growth factors and scaffold support in compromised tissue environments. The omega-3 content reduces inflammatory burden while promoting granulation tissue formation and epithelialization, even in patients with significant comorbidities.

Burn Wounds
Severity: Partial and full-thickness thermal injuries
Thermal injuries destroy the skin's barrier function and dermal structures, requiring immediate intervention to prevent infection, fluid loss, and systemic complications. Burn wounds present unique healing challenges: the inflammatory response is intense and protracted, bacterial colonization risk is extremely high, and scar formation is nearly inevitable without optimal wound management. Modern burn care emphasizes early biological coverage to minimize complications and optimize functional outcomes.
The wound healing sequence in burns is distinctly different from other trauma: initial necrotic tissue must be removed (eschar debridement), followed by a critical phase requiring biological scaffold support to guide granulation tissue formation. Traditional approaches relying solely on autografting may result in extensive scarring, contractures, and functional impairment. Biologic integration provides superior outcomes with less donor site morbidity.
How Sunspot's Products Help: Kerecis fish skin grafts accelerate the healing timeline and reduce scarring compared to standard approaches. Clinical evidence shows healing times of 17 days with Kerecis versus 23 days with standard care. The biologic scaffold promotes organized granulation tissue formation and supports epithelialization with superior cosmetic and functional outcomes.

Surgical Wounds
Applications: Post-operative closure, donor sites, Mohs surgery, complex closures
Surgical wounds range from clean, straightforward closures to complex defects requiring advanced tissue approximation and specialized reconstruction. While most surgical wounds heal without complication, certain scenarios benefit significantly from advanced closure technologies: extensive donor site harvesting, Mohs micrographic surgery with significant defects, vascular reconstruction, and complex wound geometry that challenges traditional suturing approaches.
The ideal surgical closure minimizes tissue trauma, provides secure wound approximation, reduces inflammatory response, and optimizes healing while minimizing scarring and complications. Traditional suturing, while effective, can create tissue trauma, foreign body reactions, and visible scarring. Modern biologic closure systems offer superior outcomes with reduced inflammation and improved aesthetic results.
How Sunspot's SYLKE Spider Silk Dressing Helps: SYLKE provides optimal wound approximation using hypoallergenic silk fibroin strips that integrate naturally with tissue. The system reduces inflammatory response compared to traditional sutures, minimizes tissue trauma, and provides superior aesthetic outcomes while maintaining secure closure. Ideal for facial reconstruction, Mohs defects, and complex surgical wounds.

Trauma Wounds
Types: Lacerations, abrasions, skin tears, degloving injuries
Traumatic injuries present diverse challenges depending on mechanism, depth, contamination status, and associated systemic injury. From simple lacerations to complex degloving injuries, the wound healing response involves initial inflammation, hemostasis, tissue approximation, and restoration of barrier function. The goal is not only closure but restoration of function with minimal scarring and infection risk.
Many trauma wounds benefit from both immediate closure optimization and biological support for tissue regeneration. Contaminated wounds require careful assessment and often staged management. Complex wounds with tissue loss, vascular compromise, or extensive surrounding injury benefit from advanced biological support alongside skilled surgical management.
How Sunspot's Products Help: Both Kerecis and SYLKE address different aspects of trauma wound management. SYLKE provides superior closure for acute lacerations and tissue approximation, while Kerecis supports tissue regeneration in wounds with tissue loss or extensive injury. Combined approaches optimize outcomes in complex trauma scenarios.
