Bones of the Lower Limb: Femur and Patella01:16

Bones of the Lower Limb: Femur and Patella

9.1K
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

3.6K
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...

Bones of the Upper Limb: Humerus01:19

Bones of the Upper Limb: Humerus

13.4K
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...

Structural Joints: Synovial Joints01:16

Structural Joints: Synovial Joints

9.5K
Synovial joints are the most common type of joint in the body. A key structural characteristic for a synovial joint is the presence of a joint cavity. This fluid-filled space is where the articulating surfaces of the bones contact each other. Also, unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly...

Ankle Joint01:10

Ankle Joint

3.5K
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...

Structural Joints: Cartilaginous Joints01:17

Structural Joints: Cartilaginous Joints

4.8K
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:

  • Orthopedics
  • Biomechanics
  • Anatomy

Background:

  • The acetabular labrum is a key hip joint structure.
  • It plays a critical role in joint lubrication, load distribution, and stability.
  • Recent research highlights its importance in hip health.

Purpose of the Study:

  • To review the anatomy and biomechanical function of the acetabular labrum.
  • To examine how surgical techniques impact labral function.
  • To provide insights into managing labral damage.

Main Methods:

  • Literature review of anatomical and biomechanical studies.
  • Analysis of current surgical techniques for acetabular labrum repair.
  • Discussion of the functional consequences of surgical interventions.

Main Results:

  • The labrum enhances joint lubrication by retaining intra-articular fluid.
  • It contributes to hip stability via a suction effect around the femoral head.
  • Increased contact area due to the labrum reduces stress on the joint.

Conclusions:

  • The acetabular labrum is essential for optimal hip function.
  • Surgical interventions must aim to preserve or restore labral function.
  • Continued research is needed to refine surgical techniques for labral repair.
