Muscles of the Shoulder01:23

Muscles of the Shoulder

9.2K
The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.

The anterior thoracic muscles include the serratus anterior, subclavius, and...

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...

Reversible and Irreversible Processes01:14

Reversible and Irreversible Processes

5.8K
The thermodynamic processes can be classified into reversible and irreversible processes. The processes that can be restored to their initial state are called reversible processes. It is only possible if the process is in quasi-static equilibrium, i.e., it takes place in infinitesimally small steps, and the system remains at equilibrium However, these are ideal processes and do not occur naturally. An ideal system undergoing a reversible process is always in thermodynamic equilibrium within...

Diode: Reverse bias01:14

Diode: Reverse bias

2.0K
A diode is reverse-biased when the positive terminal of an external voltage source is connected to the n-type material and the negative terminal to the p-type material. This configuration opposes the natural direction of current flow through the diode, effectively increasing the width of the depletion region and the barrier potential. The reverse bias condition produces a minimal leakage current, primarily due to minority charge carriers. This leakage becomes significant when the reverse...

Modeling of Diode Reverse Characteristics01:14

Modeling of Diode Reverse Characteristics

622
In electronic circuits, reverse-biased diode configurations are critical for regulating voltage levels. Zener diodes exploit the reverse breakdown phenomenon and exhibit a controlled breakdown at a specific Zener voltage (VZ). They are designed to maintain a constant voltage across their terminals and are commonly used for voltage regulation in circuits.
When a reverse voltage applied to a Zener diode exceeds its breakdown voltage, the diode enters the breakdown region. At this point, the...

Entropy Change in Reversible Processes01:10

Entropy Change in Reversible Processes

3.2K
In the Carnot engine, which achieves the maximum efficiency between two reservoirs of fixed temperatures, the total change in entropy is zero. The observation can be generalized by considering any reversible cyclic process consisting of many Carnot cycles. Thus, it can be stated that the total entropy change of any ideal reversible cycle is zero.
The statement can be further generalized to prove that entropy is a state function. Take a cyclic process between any two points on a p-V diagram.

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering
  • Radiology

Background:

  • Instability arthropathy can develop after shoulder surgery or naturally.
  • Reverse shoulder arthroplasty (RSA) is a treatment option for complex shoulder conditions.

Purpose of the Study:

  • To evaluate the long-term clinical and radiographic outcomes of RSA in patients with instability arthropathy.
  • To compare outcomes based on prior surgical interventions for instability.

Main Methods:

  • Retrospective cohort study of 25 patients with instability arthropathy.
  • Mean follow-up of 6.6 years.
  • Clinical assessment using Constant Score (CS); radiographic evaluation (AP and Y views).

Main Results:

  • Significant improvements in active anterior elevation (70° to 140°) and external rotation (9° to 21°).
  • Adjusted CS increased significantly (38 to 98).
  • Low complication rate (2 early post-operative), no dislocations or neurologic issues; high patient satisfaction.

Conclusions:

  • RSA demonstrates favorable clinical results and low complication rates for instability arthropathy.
  • Patient satisfaction with RSA is high, exceeding that of anatomic total shoulder arthroplasty (TSA) for this indication.
  • Clinical outcomes are consistent with existing literature on RSA.
