Muscles of the Shoulder01:23

Muscles of the Shoulder

9.1K
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.
Anterior Thoracic Muscles
The anterior thoracic muscles include the serratus anterior, subclavius, and...

Microtubule Instability02:17

Microtubule Instability

6.2K
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...

Statistical Software for Data Analysis and Clinical Trials

1.5K
Statistical software is pivotal in data analysis and clinical trials by providing tools to analyze data, draw conclusions, and make predictions. These software packages range from simple data management applications to complex analytical platforms, supporting various statistical tests, models, and simulation techniques. Their significance lies in their ability to handle vast amounts of data with precision and efficiency, enabling researchers to validate hypotheses, identify trends, and make...

Clinical Trials: Overview

4.9K
Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...

Trial and Error and Algorithm01:12

Trial and Error and Algorithm

411
A problem-solving strategy is a plan of action used to find a solution. Different strategies have distinct action plans. Trial and error involves trying different solutions until one works. For instance, to fix a broken printer, you might check ink levels, ensure the paper tray isn't jammed, and verify the printer's connection to your laptop. This method can be time-consuming but is commonly used. Thomas Edison, for example, used trial and error to find a suitable filament for the light...

Clinical Trials

10.5K
Clinical trials are prospective experimental studies conducted on humans to determine the safety and efficacy of treatments, drugs, diet methods, and medical devices. Using statistics in clinical trials enables researchers to derive reasonable and accurate conclusions from the collected data, allowing them to make wise decisions in uncertain situations. In medical research, statistical methods are crucial for preventing errors and bias.
There are four phases in a clinical trial. A phase one...

Area of Science:

  • Orthopedic surgery
  • Sports medicine
  • Surgical techniques

Background:

  • Arthroscopic repair is increasingly preferred over open repair for Bankart lesions.
  • Randomized controlled trials comparing these techniques are crucial for evidence-based practice.

Purpose of the Study:

  • To evaluate and compare the outcomes of arthroscopic versus open Bankart repair.
  • To synthesize evidence from randomized controlled trials on surgical techniques for Bankart lesions.

Main Methods:

  • Systematic literature search of Cochrane library, PubMed, and EMBASE up to December 2017.
  • Meta-analysis using fixed or random effects models based on heterogeneity.
  • Analysis of dichotomous variables (Risk Ratios) and continuous data (measured differences).

Main Results:

  • Five studies with sample sizes from 42 to 196 were included.
  • Open repair demonstrated superior shoulder stability (RR=0.897) but higher loss of external rotation.
  • Functional outcomes (Rowe score) favored open repair; operative time was shorter in arthroscopic repair, though not statistically significant.

Conclusions:

  • Arthroscopic repair enhances shoulder mobility.
  • Open repair is superior for achieving shoulder stability in Bankart lesion treatment.
  • The choice of technique involves a trade-off between stability and range of motion.
