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,...
Muscles of the Leg that Move the Foot and Toes01:28

Muscles of the Leg that Move the Foot and Toes

The human leg comprises an intricate system of muscles that facilitate the movement of feet and toes. Within this system, the muscles are categorized into the anterior, lateral, and posterior compartments, each with a unique set of muscles carrying out specific functions.
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles.
Bones of the Lower Limb: Tibia and Fibula01:10

Bones of the Lower Limb: Tibia and Fibula

The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...
Ankle Joint01:10

Ankle Joint

The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...
Pulse Assessment Sites01:11

Pulse Assessment Sites

Pulse assessment sites are crucial in evaluating a patient's cardiovascular health. By assessing the pulsations of arteries at specific anatomical locations, healthcare professionals can gather valuable information about blood flow, heart rate, and peripheral circulation. Understanding these pulse assessment sites is essential for conducting comprehensive cardiovascular evaluations and monitoring patients' overall health. These sites are strategically chosen due to the accessibility and...

Area of Science:

  • Orthopedic Surgery
  • Podiatric Medicine
  • Vascular Surgery

Context:

  • Partial foot amputations are indicated when conservative treatments fail.
  • Peripheral vascular disease presents unique challenges and contraindications.
  • Preserving stump length is key for weight-bearing and prosthesis-free ambulation.

Purpose:

  • To review the indications, techniques, and outcomes of partial foot amputations.
  • To highlight the benefits of preserving foot length and minimizing tissue loss.
  • To discuss the "hidden" amputation technique for improved patient acceptance.

Summary:

  • Surgical technique involves preserving digits and neurovascular supply where possible, with longitudinal amputations preferred for load-bearing.
  • The "hidden" amputation technique, resecting bones without removing toes, enhances patient psychological well-being.
  • Postoperative management includes protected weight-bearing and specialized prosthetics or orthopedic footwear.

Impact:

  • Partial foot amputations can lead to functional ambulation without prostheses, improving quality of life.
  • Wound healing complications occur in over half of cases, necessitating careful management.
  • Stump revision surgeries are required in 20-30% of cases, but higher-level amputations are rarely needed.
