Ankle Joint

1.4K
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...

Area of Science:

  • Microsurgery
  • Orthopedic Surgery
  • Plastic Surgery

Background:

  • Lateral ankle soft tissue defects present significant reconstructive challenges.
  • Chronic pressure and open joints complicate defect management.
  • Traditional fasciocutaneous flaps can lead to donor site morbidity.

Purpose of the Study:

  • To present a case of diabetes-related lateral ankle defect reconstruction.
  • To evaluate the efficacy of an adiposal layer only flap (pure fat flap).
  • To review the anatomy and surgical technique of this flap for ankle coverage.

Main Methods:

  • A perforator-based adiposal layer only flap was elevated from the peroneal artery.
  • Flap perfusion was confirmed using indocyanine green video angiography and color duplex ultrasound.
  • The flap was used to cover a complex lateral ankle defect.

Main Results:

  • Successful reconstruction of the lateral ankle defect was achieved.
  • The pure fat flap effectively obliterated dead space and provided a gliding surface.
  • The patient experienced a successful recovery with minimal donor site morbidity.

Conclusions:

  • The adiposal layer only flap is a viable option for complex lateral ankle soft tissue defects.
  • This technique preserves subdermal plexus and deep fascia, enhancing functional outcomes.
  • It expands reconstructive microsurgical options for challenging ankle coverage cases.
