Ankle Joint01:10

Ankle Joint

3.6K
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...

Knee Joint01:23

Knee Joint

3.7K
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...

Bone Markings01:26

Bone Markings

8.8K
Bones have various surface features that help form joints and attach to other soft tissues. Depending on the function, bone markings are categorized into articulating projections, processes for attachment, depressions, and openings.
Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...

Bones of the Lower Limb: Femur and Patella01:16

Bones of the Lower Limb: Femur and Patella

9.2K
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...

Bone Disorders01:29

Bone Disorders

7.5K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Structural Joints: Cartilaginous Joints01:17

Structural Joints: Cartilaginous Joints

4.9K
As the name indicates, at a cartilaginous joint, the adjacent bones are united by cartilage, a tough but flexible type of connective tissue. Unlike synovial joints, these types of joints lack a joint cavity and involve bones joined together by either hyaline cartilage or fibrocartilage.
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary...

Area of Science:

  • Orthopedic Surgery
  • Biomaterials Science
  • Biomechanics

Background:

  • Squeaking is a known complication in hard-on-hard bearings, particularly in hip implants.
  • The exact causes of squeaking are multifactorial, involving patient, implant, and surgical elements.
  • Damage to the fluid film lubrication is a suspected primary mechanism.

Purpose of the Study:

  • To review the current literature on the phenomenon of squeaking in hip implants.
  • To discuss the contributing factors and potential mechanisms behind squeaking.
  • To outline current diagnostic and management strategies for squeaking.

Main Methods:

  • Literature review of studies on hip implant squeaking.
  • Analysis of factors contributing to squeaking, including edge loading, wear, impingement, and material properties.
  • Discussion of clinical presentation, diagnostic imaging (e.g., CT scans), and treatment options.

Main Results:

  • Squeaking is linked to factors like edge loading, wear patterns, impingement, and ceramic fracture.
  • Implant design, metallurgic composition, and positioning can influence noise generation.
  • While often asymptomatic, severe cases may necessitate surgical intervention.

Conclusions:

  • Squeaking in hip implants is a complex phenomenon requiring a multifactorial approach for understanding and management.
  • Further research is needed, especially concerning newer large-head ceramic-on-ceramic bearings.
  • Treatment ranges from conservative measures to surgical revision depending on severity and underlying causes.
