Ankle Joint01:10

Ankle Joint

3.8K
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...

Fractures: Bone Repair

6.9K
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Bones of the Lower Limb: Tibia and Fibula

15.7K
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...

Knee Joint01:23

Knee Joint

3.8K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

Summary

Immediate reimplantation of extruded talus after debridement can yield good results. This study evaluated six patients with open total talar dislocation, finding reimplantation a viable option despite risks of infection and avascular necrosis.

Area of Science:

  • Orthopedic surgery
  • Traumatology
  • Foot and ankle surgery

Background:

  • Total talar extrusion is a rare but severe injury.
  • Often associated with significant soft tissue damage.
  • Treatment consensus for extruded talus is lacking, with high risks of avascular necrosis and infection.

Purpose of the Study:

  • To retrospectively evaluate outcomes of immediate talus reimplantation in open total talar dislocation.
  • Assess the efficacy and potential complications of this surgical approach.

Main Methods:

  • Retrospective review of six patients with open total talar dislocation.
  • Surgical technique involved talus debridement, reduction, Kirschner wire fixation, and external fixation.
  • Clinical and radiographic evaluation, including AOFAS scores for some patients.

Main Results:

  • Mean follow-up was 24.2 months.
  • Two patients developed infection; one had avascular necrosis of the talus.
  • One patient required subtalar joint arthrodesis; another underwent talectomy with tibiocalcaneal arthrodesis.

Conclusions:

  • Primary talus reimplantation can lead to good functional outcomes.
  • Prompt reimplantation after debridement is recommended.
  • Predicting infection and avascular necrosis remains challenging.
