Ankle Joint01:10

Ankle Joint

3.2K
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...

Functional Classification of Joints

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.

Knee Joint01:23

Knee Joint

3.4K
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...

Microtubule Instability02:17

Microtubule Instability

6.3K
Microtubules are hollow cylindrical filaments having a diameter of approximately 25 nm and a length that varies from 200 nm to 25 μm. GTP-bound tubulin subunits form αβ-heterodimers for microtubule assembly. These core building blocks interact longitudinally, polymerizing into protofilaments. The protofilaments then interact with one another through lateral bonding forces to form stable cylindrical microtubules. These cylindrical filaments are dynamic as they undergo repeated...

Aortic Regurgitation I: Introduction01:15

Aortic Regurgitation I: Introduction

828
IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...

Rheumatic Heart Disease I: Introduction

605
Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

Summary
This summary is machine-generated.

For young, active patients with shoulder instability, Bankart repair is a primary treatment, but recurrence is common. Bony augmentation or the Latarjet procedure is often needed for recurrent cases, especially with bone loss.

Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Shoulder Instability Research

Background:

  • Anteroinferior shoulder instability often requires capsulolabral reconstruction (Bankart repair) in active patients.
  • Despite good outcomes, recurrence rates after primary repair can reach 25%, influenced by patient and surgical factors.
  • Recurrent instability necessitates thorough clinical and radiological evaluation, including CT scans for bone loss assessment.

Purpose of the Study:

  • To review current treatment strategies for anteroinferior shoulder instability and recurrent dislocations.
  • To identify risk factors for surgical failure and discuss management of complex cases.
  • To explore options for engaging Hill-Sachs lesions and managing dislocation arthropathy.

Main Methods:

  • Literature review of primary and revision shoulder stabilization techniques.
  • Analysis of risk factors associated with recurrent shoulder instability.
  • Evaluation of surgical options including Bankart repair, bone grafting (coracoid, iliac crest), Latarjet procedure, Remplissage, and arthroplasty.

Main Results:

  • Bankart repair is first-line for active patients, but recurrence is significant.
  • Glenoid bone loss and Hill-Sachs lesions are key factors in failed primary surgery.
  • For recurrent instability, bony augmentation (Latarjet, bone blocks) offers better outcomes than revision Bankart repair alone.
  • Engaging Hill-Sachs lesions require specific management; dislocation arthropathy presents as pain and restricted motion.

Conclusions:

  • Revision surgery for shoulder instability requires careful consideration of bone loss and lesion type.
  • Bony augmentation procedures like the Latarjet are effective for recurrent instability with bone loss.
  • Joint-preserving options exist for dislocation arthropathy, but consensus on Hill-Sachs lesion treatment is pending.
