Mitral Valve Prolapse I: Introduction01:27

Mitral Valve Prolapse I: Introduction

925
IntroductionThe mitral valve, one of the heart's four valves, regulates blood flow. These valves have flaps that open and close to direct blood properly through the heart and body. During each heartbeat, the flaps open for blood to pass through and seal shut to prevent backflow. Specifically, the mitral valve opens to allow blood flow from the heart's upper left chamber to the lower left chamber. It then closes securely as the lower left chamber contracts to pump blood to the body, preventing...

Ankle Joint01:10

Ankle Joint

3.6K
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...

Bones of the Lower Limb: Femur and Patella01:16

Bones of the Lower Limb: Femur and Patella

9.2K
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...

Area of Science:

  • Orthopedic Surgery
  • Traumatology
  • Elbow Biomechanics

Background:

  • Varus posteromedial instability involves injury to the coronoid process and lateral collateral ligament.
  • Nonoperative treatment is associated with poor outcomes in these injuries.

Purpose of the Study:

  • To elucidate the pathophysiology of varus posteromedial elbow instability.
  • To discuss current management strategies for this condition.
  • To report treatment outcomes.

Main Methods:

  • Surgical fixation of coronoid fractures using plates, screws, or sutures.
  • Repair of the lateral collateral ligament.
  • Review of patient outcomes and objective scoring.

Main Results:

  • Outcomes for surgical intervention are mixed, with most series reporting fair to good objective scores.
  • Surgical management is the preferred treatment modality.

Conclusions:

  • Varus posteromedial instability requires surgical intervention for optimal outcomes.
  • Further research may refine surgical techniques and improve patient prognoses.
