Bones of the Lower Limb: Femur and Patella01:16

Bones of the Lower Limb: Femur and Patella

8.2K
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...

Classification of Bones

14.3K
The bones of the human skeletal system are of varied shapes, sizes, and functions. They can be classified based on their shape and function into four major classes: long bones, short bones, flat bones, and irregular bones. Some classifications include a fifth type, the sesamoid bones, as a separate class, whereas others categorize them under short bones.
Long and Short Bones
The appendicular skeleton, particularly the upper and lower limbs, is primarily made of long and short bones. The...

Fractures: Bone Repair

5.9K
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...

Functional Classification of Joints

8.1K
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.

Bones of the Upper Limb: Humerus01:19

Bones of the Upper Limb: Humerus

11.3K
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...

Bones of the Lower Limb: Tibia and Fibula

14.7K
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...

    Summary

    Trochanteric fracture classification needs re-evaluation, particularly regarding AO subtypes and instability concepts. Focus on the lateral trochanteric wall and medial femoral shaft displacement in DHS fixation is crucial for better outcomes.

    Area of Science:

    • Orthopedic surgery
    • Traumatology
    • Bone fracture research

    Background:

    • Trochanteric fractures present ongoing classification challenges.
    • Current AO classification subtypes and instability concepts require reassessment.
    • The role of the lateral trochanteric wall is often underestimated.

    Purpose of the Study:

    • To critically evaluate the existing classification systems for trochanteric fractures.
    • To investigate the concept of instability in trochanteric fractures.
    • To highlight key anatomical features and displacement patterns relevant to treatment outcomes.

    Main Methods:

    • Review and critical analysis of current trochanteric fracture classification systems.
    • Discussion of the biomechanical implications of fracture patterns.

  • Focus on the significance of the lateral trochanteric wall and medial femoral shaft displacement.

    • Main Results:

    • The validity of individual AO classification subtypes for trochanteric fractures is questioned.
    • Instability assessment requires a more nuanced approach beyond basic fracture patterns.
    • Medial displacement of the femoral shaft, particularly concerning the lateral trochanteric wall, is a critical factor in Dynamic Hip Screw (DHS) fixation.

    Conclusions:

    • A revised approach to trochanteric fracture classification is necessary.
    • Understanding fracture instability requires attention to specific anatomical structures and displacement.
    • Optimizing DHS fixation involves careful consideration of the lateral trochanteric wall and medial femoral shaft displacement.
