Ankle Joint01:10

Ankle Joint

3.1K
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...

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...

Assessment of the Abdomen III: Palpation01:23

Assessment of the Abdomen III: Palpation

3.8K
Palpation is a crucial tactile examination method for assessing abdominal organs and detecting conditions like tenderness, distention, masses, or fluid. It involves both light and deep palpation techniques, each serving specific diagnostic purposes. Light palpation helps identify tenderness and other surface-level indicators, while deep palpation locates and assess abdominal masses and organ boundaries. A skilled professional can gather valuable insights through palpation, including evaluating...

Assessment of the Cardiovascular System III: Palpation

1.2K
Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...

Area of Science:

  • Orthopedics
  • Diagnostic Imaging
  • Sports Medicine

Background:

  • Ankle instability is commonly assessed using the anterior drawer test.
  • A novel digital palpation technique, anterolateral talar palpation (ATP), was developed to potentially improve diagnostic accuracy.

Purpose of the Study:

  • To evaluate the diagnostic accuracy of anterolateral talar palpation (ATP) for ankle instability.
  • To compare the efficacy of ATP against the traditional anterior drawer test.

Main Methods:

  • A cross-sectional study involving 14 symptomatic and 10 asymptomatic patients.
  • Two blinded orthopedic surgeons performed ATP and the anterior drawer test.
  • Comparison with stress radiography and magnetic resonance imaging (MRI) for symptomatic patients.

Main Results:

  • Anterolateral talar palpation (ATP) demonstrated high sensitivity but lower specificity.
  • ATP and radiography showed the highest accuracy and agreement with MRI findings.
  • ATP yielded more positive results compared to other diagnostic methods.

Conclusions:

  • Anterolateral talar palpation (ATP) significantly enhances the diagnostic accuracy for ankle instability.
  • ATP serves as a valuable addition to the clinical assessment of ankle instability.
