Force Classification01:22

Force Classification

2.4K
Forces play a crucial role in the study of physics and engineering. They are essential in describing the motion, behavior, and equilibrium of objects in the physical world. Forces can be classified based on their origin, type, and direction of action.
Contact and non-contact forces are two of the most widely used categories of forces. As the name suggests, contact forces require physical contact between two objects to act upon each other. Examples of contact forces include frictional,...

Classification of Neurotransmitters

5.3K
Neurotransmitters play a crucial role in the communication between neurons in the autonomic nervous system. Neurons in the autonomic nervous system can be cholinergic or adrenergic depending on the neurotransmitters synthesized. Cholinergic neurons use acetylcholine as their primary neurotransmitter. This includes all the preganglionic fibers of the sympathetic and pre- and postganglionic fibers of the parasympathetic nervous systems. In addition, neurons of the somatic nervous system also use...

Classification of Leukocytes01:30

Classification of Leukocytes

5.8K
Leukocytes are classified into two groups based on the presence or absence of cytoplasmic granules. Granular leukocytes, which contain granules, belong to the myeloid lineage and are divided into three subtypes: neutrophils, eosinophils, and basophils. These cells are roughly spherical and characterized by the granules in their cytoplasm.
Neutrophils are the most abundant type of granular leukocytes, comprising 50-70% of all leukocytes. They feature small, evenly distributed granules and a...

Classification of Illness01:17

Classification of Illness

8.7K
The meaning of illness is individualized to each person who experiences an alteration in health. In contrast, disease is a medical term indicating a pathological change in the structure and function of the body or mind. It is a condition that has specific symptoms and boundaries.
An illness is a response to a disease in which the person's level of functioning is changed compared with a previous level. The general classification of illness includes acute and chronic.
Acute illness is severe...

Classification of Bones01:18

Classification of Bones

9.9K
The bones of the human skeletal system are of varied shapes, sizes, and functions. They can be classified based on their shape and function into four major classes: long bones, short bones, flat bones, and irregular bones. Some classifications include a fifth type, the sesamoid bones, as a separate class, whereas others categorize them under short bones.
Long and Short Bones
The appendicular skeleton, particularly the upper and lower limbs, is primarily made of long and short bones. The...

Seizures: Classification

1.6K
Epilepsy is primarily characterized by unpredictable seizures, either provoked by an identifiable factor, such as injury or illness, or unprovoked, occurring spontaneously without apparent cause.
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:

Summary

A new MAS classification system for polydactyly simplifies management for both radial and ulnar hand anomalies. This approach categorizes polydactyly by attachment type, guiding surgical treatment effectively.

Area of Science:

  • Orthopedics
  • Hand Surgery
  • Congenital Anomalies

Background:

  • Polydactyly is a common congenital hand anomaly with existing classifications for specific types.
  • Current classifications do not comprehensively address both radial and ulnar polydactyly under a unified system.
  • A need exists for a classification that integrates different polydactyly variants and guides management algorithmically.

Purpose of the Study:

  • To propose a novel classification system (MAS classification) for polydactyly.
  • To include both radial and ulnar polydactyly variants within a single classification framework.
  • To develop an algorithmic approach for managing polydactyly based on the proposed classification.

Main Methods:

  • A case series of 11 consecutive patients diagnosed with hand polydactyly.
  • Patients underwent physical assessment and X-ray examination.
  • Cases were categorized using the proposed MAS classification system.

Main Results:

  • The MAS classification categorizes polydactyly into three main types: A (soft tissue attachment), B (bone attachment), and C (joint attachment).
  • Subtypes detail specific anatomical locations of attachment (e.g., metacarpal bone, proximal phalanx, metacarpophalangeal joint).
  • An algorithmic treatment approach was outlined: soft-tissue excision for type A, bony excision for type B, and ligament reconstruction for type C.

Conclusions:

  • The MAS classification is applicable to both ulnar and radial polydactyly.
  • The system is simple, memorable, and anatomically/surgically oriented.
  • Further validation through extensive studies is recommended.
