Diabetic Foot Ulcer01:31

Diabetic Foot Ulcer

Definition A diabetic foot ulcer (DFU) is a chronic, non-healing wound that develops in individuals with diabetes. It typically occurs on pressure-bearing areas such as the heel, metatarsal heads, or hallux, and carries a high risk of infection and amputation.Pathophysiology • The development of DFUs can be explained by four interconnected mechanisms: neuropathy, ischemia, infection, and impaired wound healing. • Neuropathy is the most common factor. Sensory neuropathy reduces pain perception,...
Diabetic Neuropathy01:22

Diabetic Neuropathy

DefinitionDiabetic neuropathy is nerve damage caused by long-standing diabetes mellitus. It results directly from prolonged high blood sugar levels.PathophysiologyThe pathophysiology of diabetic neuropathy involves both metabolic and vascular disturbances triggered by chronic hyperglycemia.Metabolic injury: Elevated glucose levels activate the polyol pathway within nerve cells, leading to the accumulation of sorbitol and fructose. This increases oxidative stress, disrupts normal nerve...
Complications of Diabetes Mellitus01:22

Complications of Diabetes Mellitus

Diabetes mellitus is a chronic metabolic disorder characterized by persistent hyperglycemia due to insulin deficiency, resistance, or both. Prolonged hyperglycemia disrupts metabolic homeostasis and leads to acute and chronic complications.Acute ComplicationsAcute complications result from sudden metabolic imbalance.Diabetic ketoacidosis (DKA) mainly appears in type 1 diabetes but may also develop in type 2 diabetes, particularly under extreme stress. It arises from severe insulin deficiency,...

Peripheral Artery Disease V: Postoperative Nursing Management

During the postoperative period, it is crucial to focus on maintaining circulation, identifying and managing potential complications, and planning for discharge.Nursing AssessmentVital signs monitoring: Regularly monitor vital signs, including blood pressure, heart rate, respiratory rate, and temperature, to detect early signs of complications such as bleeding and infection.Circulation assessment: Monitor pulses, perform Doppler assessments, and check capillary refill, color, temperature, and...
Diabetic Retinopathy01:27

Diabetic Retinopathy

DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
Peripheral Artery Disease III: Interprofessional Care01:27

Peripheral Artery Disease III: Interprofessional Care

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

Area of Science:

  • Orthopedic Surgery
  • Rehabilitation Medicine
  • Biomedical Engineering

Background:

  • Major lower extremity amputation presents significant challenges for patient mobility and quality of life.
  • Achieving optimal residual limb function is paramount for successful prosthetic use and rehabilitation.

Purpose of the Study:

  • To outline a systematic surgical approach for major lower extremity amputations.
  • To emphasize the importance of preoperative optimization and creative tissue utilization for functional outcomes.

Main Methods:

  • Systematic review of surgical techniques for lower extremity amputation.
  • Focus on preoperative evaluation of biomechanics, vascular status, and infection control.
  • Principles of tenodesis and prosthetic coordination for joint motion and muscle tone.

Main Results:

  • A structured approach can enhance the functional capacity of the residual limb.
  • Careful preoperative assessment and management of factors like blood flow and infection are critical.
  • Strategic use of viable tissues can improve prosthetic fitting and performance.

Conclusions:

  • Optimizing residual limb length and muscle function is key to maximizing post-amputation mobility.
  • Preoperative optimization and surgical planning significantly impact the functional success of lower extremity amputations.
  • Most amputees can achieve a highly functional lower extremity with thoughtful surgical technique and prosthetic integration.
