Fractures: Bone Repair01:27

Fractures: Bone Repair

2.8K
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...

Bone Disorders01:29

Bone Disorders

3.4K
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...

Bones of the Lower Limb: Femur and Patella01:16

Bones of the Lower Limb: Femur and Patella

2.0K
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...

Bones of the Lower Limb: Tibia and Fibula

2.4K
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...

Osteoclasts in Bone Remodeling01:31

Osteoclasts in Bone Remodeling

2.8K
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...

Bone Remodeling01:40

Bone Remodeling

38.0K
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

Area of Science:

  • Orthopedic surgery
  • Geriatric medicine
  • Biomaterials science

Background:

  • Tibial plateau fractures are common in the elderly, often caused by low-energy trauma.
  • Osteoporosis, osteoarthritis, and comorbidities complicate treatment in this demographic.

Purpose of the Study:

  • To review current treatment strategies for proximal tibial fractures in the elderly.
  • To explore innovative approaches integrating biomechanical, biological, and technological advancements.
  • To address the lack of comprehensive studies on improving fixation outcomes in osteoporotic bone.

Main Methods:

  • Comprehensive literature review of internal and external fixation techniques.
  • Discussion of medical management and acute arthroplasty options.
  • Exploration of advanced materials and regenerative technologies for enhanced fixation.

Main Results:

  • Osteoporotic bone presents significant challenges to fracture fixation, increasing failure rates.
  • Current literature highlights the need for integrated approaches to improve fixation efficacy.
  • Innovative strategies are being explored to enhance fixation success in elderly patients.

Conclusions:

  • Management of proximal tibial fractures in the elderly requires a tailored, individualized approach.
  • Integration of surgical intervention with medical management is critical for optimal outcomes.
  • A comprehensive strategy is essential to improve recovery and quality of life.
