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,...
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...

Area of Science:

  • Orthopedic surgery
  • Rehabilitation medicine
  • Prosthetics and orthotics

Background:

  • Transtibial amputations aim to maximize stump length for optimal load-bearing and pain-free function.
  • Preserving the knee joint is a primary goal in lower limb amputation surgery.
  • Ultra-short tibial stumps (5-6 cm) may be indicated to retain knee joint function.

Purpose of the Study:

  • To explore surgical techniques and postoperative management for achieving long, pain-free transtibial stumps with maximum terminal load-bearing.
  • To evaluate the feasibility and outcomes of ultra-short tibial stumps for knee joint preservation.

Main Methods:

  • Review of surgical techniques including posterior muscular flaps, fibular bone bridges, soleus muscle resection, myodesis, and rotation plasty.
  • Discussion of contraindications for distal tibial amputations in peripheral vascular disease.
  • Description of postoperative management including elastic bandaging, early prosthetic fitting, physical therapy, and stump shaping.

Main Results:

  • Wound healing complications can necessitate re-amputation, even above the knee, when maximizing stump length.
  • Preserving the knee joint, even with an ultra-short stump, leads to significantly better rehabilitation outcomes compared to more proximal amputations.
  • Successful outcomes depend on meticulous surgical technique and comprehensive postoperative care.

Conclusions:

  • Ultra-short transtibial stumps are a viable option for knee joint preservation, offering superior functional recovery.
  • Careful patient selection, surgical technique, and dedicated rehabilitation are essential for optimizing outcomes in transtibial amputations.
  • Long-term stump remodeling and prosthesis adjustment are critical components of successful rehabilitation.
