Summary
Humerus torsion, or retroversion, is crucial for shoulder surgeries and fracture treatments. Precise measurement, often using computed tomography, ensures accurate anatomical reconstruction for better patient outcomes.
Area of Science:
- Orthopedic surgery
- Radiology
- Anatomy
Background:
- Humerus torsion refers to the physiological rotation of the humerus along its axis.
- Accurate measurement of humerus retroversion is vital for treating various shoulder pathologies.
Purpose of the Study:
- To highlight the importance of humerus retroversion in orthopedic procedures.
- To emphasize the computed tomography method as the gold standard for measurement.
Main Methods:
- Review of clinical and radiological measurement techniques for humerus torsion.
- Computed tomography (CT) as the current gold standard for measuring the angle between the humeral head axis and the transepicondylar axis (retroversion).
Main Results:
- Humerus retroversion values typically range from 10° to 40°.
- Precise reconstruction of anatomical retroversion is necessary for effective treatment of humeral pathologies.
Conclusions:
- Accurate humerus retroversion measurement is essential for shoulder arthroplasty, fracture management, and correcting post-traumatic deformities.
- Contralateral side orientation is recommended when original anatomical landmarks are unclear.

01:16Torsion of Noncircular Members
617
Circular shafts undergoing torsional stress maintain their cross-sectional integrity due to their axisymmetric nature. This symmetry ensures an even distribution of stress, allowing the shaft to withstand torsion without distorting. In contrast, square bars, lacking this axial symmetry, experience significant distortion across their cross-sections when subjected to torsion, with the exception of along their diagonals and at lines connecting midpoints. A detailed examination of a cubic element...

01:09Torsional Pendulum
7.5K
A torsional pendulum involves the oscillation of a rigid body in which the restoring force is provided by the torsion in the string from which the rigid body is suspended. Ideally, the string should be massless; practically, its mass is much smaller than the rigid body's mass and is neglected.
As long as the rigid body's angular displacement is small, its oscillation can be modeled as a linear angular oscillation. The amplitude of the oscillation is an angle. The role of mass is played...

5.9K
Bending and torsional moments are two fundamental concepts in structural engineering. They play an important role in understanding the behavior of materials and structures under different loading conditions.
The reaction developed in a structural element when subjected to an external force causes the element to bend. When a structural element bends upwards, it creates compressive normal forces on the top and tensile normal forces on the bottom, resulting in a couple that determines the bending...

01:19Bones of the Upper Limb: Humerus
7.5K
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...

02:02DNA Topoisomerases
35.9K
Topoisomerases are enzymes that relax overwound DNA molecules during various cell processes, including DNA replication and transcription. These enzymes regulate positive and negative DNA supercoiling without changing the nucleotide sequence. DNA overwinding in a clockwise direction results in positively supercoiled DNA, whereas underwinding in a counterclockwise direction produces negatively supercoiled DNA.
Types and Mechanism of action
