Bones of the Lower Limb: Femur and Patella01:16

Bones of the Lower Limb: Femur and Patella

2.2K
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...

Impact01:30

Impact

137
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...

Knee Joint01:23

Knee Joint

1.5K
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...

Articulations of the Vertebral Column01:28

Articulations of the Vertebral Column

1.8K
In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...

Ankle Joint01:10

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...

Functional Classification of Joints01:09

Functional Classification of Joints

3.8K
Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses  or amphiarthroses, whereas all synovial joints are classified as diarthroses.
Synarthrosis

Area of Science:

  • Orthopedic Surgery
  • Trauma Surgery
  • Radiology

Background:

  • Articular surface impactions are critical prognostic factors in acetabular fracture treatment.
  • Impactions can occur at the posterior margin, acetabular dome, or involve the femoral head, influenced by trauma mechanisms.

Purpose of the Study:

  • To review the types of articular surface impactions associated with acetabular fractures.
  • To discuss diagnostic methods and surgical reduction techniques for different impaction types.

Main Methods:

  • Review of literature on acetabular fractures and articular surface impactions.
  • Discussion of diagnostic utility of thin-slice CT scans.
  • Description of surgical approaches for posterior marginal and acetabular dome impactions.

Main Results:

  • Posterior marginal impactions are linked to posterior fracture dislocations.
  • Acetabular dome impactions are common in elderly patients with extended hip trauma.
  • Femoral head impactions frequently accompany fracture dislocations and transverse acetabular fractures.

Conclusions:

  • Preoperative identification of impactions via CT scans is essential.
  • Surgical reduction strategies vary based on impaction location, utilizing posterior approaches or cortical windows.
  • Bone grafting or substitutes are used to fill voids post-reduction.
  • Clear treatment guidelines for femoral head impactions are lacking.
