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.

High-Resolution Three-Dimensional Imaging of the Footpad Vasculature in a Murine Hindlimb Gangrene Model

Published on: March 16, 2022

Area of Science:

  • Orthopedic surgery
  • Trauma surgery
  • Podiatric surgery

Context:

  • Complex foot trauma and infection necessitate limb salvage procedures.
  • Preserving limb length and function is a key goal in foot amputations.
  • Hindfoot amputations aim to create a durable, weight-bearing stump with intact heel sensation.

Purpose:

  • To describe and evaluate Chopart, Pirogoff, and Syme hindfoot amputation techniques.
  • To assess the outcomes of these amputations in patients with complex foot conditions.
  • To determine the feasibility of achieving a functional, weight-bearing stump with preserved heel sensation.

Summary:

  • The study details surgical techniques for Chopart, Pirogoff, and Syme amputations, focusing on flap design and bone/tendon management.
  • Over a 12-year period, 24 hindfoot amputations were performed for trauma, infection, and Charcot foot.
  • Postoperative management included non-weight bearing, casting, and prosthetic fitting. Revisions were common, particularly for infections.

Impact:

  • Most patients with hindfoot amputations could walk barefoot, indicating successful functional restoration.
  • These techniques offer limb salvage options for severe foot pathology, improving patient mobility.
  • The study highlights the importance of careful surgical technique and postoperative care for optimal outcomes in hindfoot amputations.
