Bones of the Lower Limb: Tibia and Fibula01:10

Bones of the Lower Limb: Tibia and Fibula

13.7K
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...

Bones of the Lower Limb: Femur and Patella

8.8K
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...

Knee Joint01:23

Knee Joint

3.5K
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...

Ankle Joint01:10

Ankle Joint

3.2K
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...

Impact01:30

Impact

542
Impact occurs when two bodies collide, leading to the application of impulsive forces between them. Analyzing impact mechanics involves considering two colliding particles moving along a line known as the line of impact, which passes through their centers and is perpendicular to the contact plane.
When particles with different initial velocities collide, they induce deformation by applying equal and opposite impulses. At the point of maximum deformation, the particles move together with...

Arteries of Lower Limbs01:20

Arteries of Lower Limbs

5.2K
The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular...

Area of Science:

  • Orthopedic surgery
  • Traumatology
  • Biomaterials science

Background:

  • Articular impacted fractures necessitate precise management to restore joint congruency and stability.
  • Osteochondral fragments require anatomical reduction and secure fixation for optimal articular surface function.

Purpose of the Study:

  • To review current techniques and materials for managing impacted osteochondral fragments.
  • To discuss the epidemiology and treatment options for these specific fracture types.

Main Methods:

  • Review of surgical techniques for osteochondral fragment elevation (cortical window, balloon-guided osteoplasty, direct visualization).
  • Evaluation of bone graft materials (autologous tricortical bone) and synthetic substitutes for subchondral void support.

Main Results:

  • Multiple surgical approaches exist for fragment elevation, each with specific indications.
  • Both autologous bone grafts and synthetic substitutes can provide structural support to the subchondral defect.

Conclusions:

  • Successful treatment hinges on fragment elevation, joint congruency restoration, and stable fixation.
  • A comprehensive understanding of available techniques and materials is crucial for effective management of impacted osteochondral fractures.
