Bone Disorders01:29

Bone Disorders

4.9K
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...

Ankle Joint01:10

Ankle Joint

2.3K
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

2.8K
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...

Fractures: Bone Repair01:27

Fractures: Bone Repair

4.3K
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...

Summary

New safety protocols are needed for orthopedic and spine surgery patients during the COVID-19 pandemic. This review highlights SARS-CoV-2

Area of Science:

  • Infectious Diseases
  • Orthopedic Surgery
  • Spine Surgery

Background:

  • The COVID-19 pandemic necessitates updated safety protocols in surgical settings.
  • Understanding SARS-CoV-2's impact on hemoglobin and coagulation is crucial.

Purpose of the Study:

  • To determine new safety protocols for orthopedic and spine surgery patients at risk of COVID-19 infection or transmission.
  • To address patient comorbidities in both outpatient and inpatient settings.

Main Methods:

  • Systematic literature review focusing on COVID-19 and its relevance to orthopedic and spine surgery.

Main Results:

  • SARS-CoV-2 affects hemoglobin and can cause intravascular disseminated coagulation (IDC).
  • The virus adheres to surfaces, and associated pneumonia requires specific ventilator management.
Keywords:
COVID-19SARS-CoV-2viral adherenceviral biofilm
