Basic hand anatomy: the three main joints of our fingers


First Phalanx

The first phalanx of the finger includes the tip of the finger and the nail. The tips of the fingers, both on the hands and feet, are the limits of the limbs. They are the first to shiver and ache if the body is exposed to cold. They give the palmist the first impression of a person and his nature, show how the subject perceives the world around him and what influence he himself has on the world.

Long first phalanges of fingers

Such people are intuitive, easy to learn and well organized. Their outlook on life is philosophical and religious to a greater extent than materialistic. These people enjoy mental activity, they love new ideas and are very entertaining.

Short first phalanges

Found in materialistic, practical and suspicious people. They understand only what can be touched, they have no inspiration and no sense of the influence of fate. They are too lazy to think and are not inclined to study and master new concepts.

Rounded fingertips

Such people do not like friction and disagreement. They look for beauty, truth in life and are often too trusting; they are creative people with broad views, capable of making very wise, cunning, thoughtful, careful and honest decisions.

Pointed fingertips

Such people have a sharp mind and high intelligence, quick reactions. They get to the heart of things, quickly analyze the situation, but cannot see it as a whole. They instinctively react to others and instantly form their attachments and hostile attitudes. Once an opinion is formed, they act uncompromisingly in the future. As a result, they are unable to act diplomatically or see beyond appearances or find excuses in the behavior or attitudes of people they do not accept. They have excellent organizational and presentation skills, but they cannot cope with an excess of details.

Dreamers have very pointed fingertips. Such people are cautious, straightforward, and have their own idea of ​​the lifestyle that will suit them best. They are often very attractive in appearance, pay attention to their appearance and are very vain. They can often be an inspiration to others, but they lack the energy to do much for themselves and are not eager to do anything for others.

Spatula-shaped fingertips

Such fingertips are found in independent, sociable people who are constantly thinking about something. They can see the whole picture and put the pieces together, which is why they are scientists and lawyers, successful athletes and performers. They love to combine the fruits of their labors and thoughts, so they are often very enterprising and inventive craftsmen and engineers.

Square fingertips

People with such fingertips are down to earth, with their feet firmly planted on the ground, they have rough manners and a slow mind. Usually they are conformists, so they can be dogmatic and conservative, they love when justice is done. If the phalanxes are long, then these are usually good lawyers, bankers, clerks and advisers. They work well with documents and are able to take into account many details.

Profile of the first phalanx

Conical profile (Fig. 3.8)

People with a conical phalanx profile are very smart, but they also lack physical strength. They have a well-developed imagination. They are loving, gentle and deeply spiritual natures.

Rough finger profile (Fig. 3.9)

People with this finger are materialistic, sensual, grounded, self-indulgent and sometimes rude. If the phalanx of the finger is short, then they can be laborers, performers without imagination. When the phalanx is long, these gifted people are very tough in business and cannot be defeated in an argument.

Convex, drop-like horseman (Fig. 3.10)

In this case, people are refined, and they have a well-developed sense of touch. They are smart, rarely lose or lose anything, are very receptive, have high intelligence and creativity. They have a well-developed sense of touch, which is very useful when sewing clothes, gardening, creating sculptures or playing musical instruments. These inclinations are much more pronounced if on Apollo’s finger the shape of the first phalanx very clearly resembles a drop. Their character can be very bright and attention should be paid to the line of the head to determine if it slopes towards the Mount of the Moon, indicating a very receptive mind.

Useful information about hand fractures

What is a hand bone fracture?

Fractures of the hand bones are a fairly common type of bone fracture and, according to statistics, account for about 35% of all skeletal bone fractures. The frequency of bone injuries in this segment is associated with the extremely complex function of the hand in a person’s social life, his life, professional and creative activities. The hand is formed by 22 bones and includes the carpal bones, metacarpal bones, and phalanges of the fingers.

Classification of hand bone fractures

Fractures of the hand bones include:

  • Fracture of the carpal bones, the most common fractures being the scaphoid and lunate bones. Fractures of other carpal bones are much less common;
  • Fractures of the metacarpal bones;
  • Fractures of the phalanges of the fingers.

Scaphoid fracture

A fracture of the scaphoid bone, as a rule, occurs when falling on an outstretched hand, with a direct blow to the palmar surface of the hand, etc. The peculiarity of the blood supply to the scaphoid bone determines various treatment options for fractures of this bone.

Clinical picture of a fracture of the scaphoid: in most cases, examination reveals swelling in the area of ​​the anatomical snuffbox, movements in the dorsoradial direction are limited by pain, the patient usually cannot clench the hand into a fist. Diagnosis of a scaphoid fracture includes an X-ray examination in three projections (direct, lateral and oblique), in some cases CT and MRI are performed.

Lunate fracture

A fracture of the lunate bone in most cases occurs from a fall on the hand, which is abducted to the ulnar side.

Clinical picture. Upon examination, swelling of the soft tissues in the area of ​​the wrist joint is revealed; retraction in the area of ​​the third metacarpal bone can be detected when the hand is clenched into a fist. With axial load, pain is detected in the third and fourth fingers.

Metacarpal fracture

Fracture of the metacarpal bones. The most common metacarpal fractures include the base of the first toe, Bennett's fracture, and Roland's fracture. Bennett's fracture is characterized by the presence of a longitudinal fracture of the palmar-ulnar edge of the base of the first finger. As a rule, with this fracture the fragment is triangular in shape and moves slightly, as it is held by ligaments.

The first metacarpal bone moves proximally. A Roland fracture is a comminuted fracture of the base of the first metacarpal bone. this type of fracture. Upon examination, deformation and swelling in the area of ​​the 1st metacarpal joint are revealed. Axial load on the 1st finger is painful. With a fracture of the first metacarpal bone, the thumb is adducted and slightly bent.

Fracture of the phalanges of the fingers

Fractures of the phalanges of the fingers often occur with direct and indirect injuries. As a rule, with fractures of the diaphysis, a displacement is formed with an angle open to the rear. The clinical picture is characteristic of most fractures - swelling, deformation, subcutaneous hematoma, pathological mobility, pain with axial load.

Upper, middle and lower phalanges

  • The upper phalanx is associated with spiritual, emotional and mental needs.
  • The middle phalanx is related to the application of ideas, practical implementation, and the activation of certain mechanisms.
  • The lower phalanx relates to material matters and physical needs.

Middle phalanx of the finger

In the science of palmistry, this phalanx, its shape, length, signatures are consistent with the pattern of the line of the Mind. It indicates a peculiarity of perception, the practical application of intellectual potential, and memory. At the same time, this is a reflection of the sphere of rationality, the ability to create and create something fundamentally new. The possibility of demonstrating one’s talents, as evidenced by the appearance of the middle phalanx, is absolutely rational and relates to the material sphere of life. The phalanx reflects a person’s realization in life, his objective, concrete, real consciousness.

In addition, the potential of the middle phalanx of the finger symbolizes the ability to accumulate life experience.

If necessary, a person retrieves this experience from his memory. According to Freud's theory, it is placed in the subconscious, which in chirology is symbolized by the upper part of the Mount of the Moon, and in astrology by Mercury/Virgo/6th house. As a rule, the line runs along this area of ​​the palm. With long-term storage, without practical application, the experience settles in the subconscious, which, from the point of view of chirology, refers to the Mount of the Moon. The signatures of the Mount of the Moon - in astrology these correspondences relate to the Moon/Cancer/4th house - also indicate the ability to attract the subconscious, unless this experience is consciously suppressed. This ability to extract what is necessary is related in astrology to the properties of Mercury.

The properties of Mercury, the ruler of Gemini, differ from Mercury in Virgo in that they relate to the activation of perception. The representation of the fingers in the brain, in the corresponding zone of the cortex, extracts what is of interest from the outside world, and Virgo-Mercury integrates what has been collected and, if necessary, extracts it from memory. Virgo-Mercury sorts images, analyzes them and decides what specific material is needed for rational use.

But this work of Mercury in Virgo relates mainly to the realm of the senses; intelligence, analysis and synthesis capabilities are enabled with its help a little later. The completeness and completeness of this process is reflected in the drawing of the Mind line. The type of reaction and the completeness of its implementation in practice is indicated not only by the quality of the line of the Mind, but also by the appearance of the middle phalanges. From them you can even find out whether the experience will be used practically or theoretically. In this regard, it is necessary, somewhat looking ahead, to note that, based on my practical observations, I will describe the functions of Mercury/Uranus also in relation to the papillary lines.

The capabilities of the middle phalanx largely depend on the nail: intellectual capabilities depend on the subtlety of perception. In astrology, the middle phalanges correspond to the fixed cross and its zodiac signs Taurus, Leo, Scorpio, Aquarius.

Damage to the extensor tendons of the fingers and hand

Damage to the extensor tendons is a rather complex problem in hand surgery due to the peculiarities of the anatomical structure of the extensor apparatus of the fingers. Damage to the extensor tendon leads to impaired finger extension.

Anatomically, there are 8 zones of damage to the extensor tendons:

Fig.1. Zones (levels) of damage to the extensor tendons of the hand and fingers

The symptoms and treatment method depend on the area of ​​tendon damage.

There are open and closed extensor injuries. Even a small wound on the dorsum of the fingers, hand or forearm can be complicated by tendon damage. There are frequent cases of closed, that is, subcutaneous damage to the extensor tendons. They can be the result of either a high-energy injury (falling, lifting a heavy object, etc.) or occur during everyday work (putting on clothes, making a bed, etc.). In some cases, the extensor tendons can be torn off with a piece of bone at the site of their attachment, and can also be combined with damage to other anatomical structures (vessels, nerves, ligaments, etc.). Fresh and old damage are also distinguished.

Fig.2. Damage to the extensor tendon of the finger in 1 zone

Symptoms:

The most important symptom of damage to the extensor tendon of the finger is a violation of its function: the impossibility or limitation of its extension. The finger “hangs” and it is impossible to straighten it independently, without the help of the other hand. Depending on the area of ​​damage, extension may be impaired in different joints.

Diagnostics:

Most often, to make a diagnosis, a thorough study of the patient’s medical history and disease, and an examination of the patient is sufficient. With open wounds of the hand and forearm or with chronic injuries, tendon damage can be combined with damage to nerves, blood vessels and other anatomical structures, which requires a thorough knowledge of anatomy and specialized training from the doctor.

Also, to clarify the diagnosis and differential diagnosis, in some cases additional studies are required, such as radiography, ultrasound, computed tomography, magnetic resonance imaging.

Treatment for extensor tendon injuries:

Treatment tactics for damage to the extensor tendons depend on the area of ​​the tendon damage, the nature of the damage (open or closed), the individual characteristics of the patient, as well as some other factors.

Conservative treatment:

For some types of damage to the extensor tendons (for example, with closed damage in zone 1), conservative treatment is possible, which consists of applying a special splint to the finger. The splint keeps the finger in the correct position while the tendon heals. After removing the splint, it is important to properly “wean off” it, otherwise the treatment result may be incomplete.

Surgery:

The vast majority of extensor tendon injuries require surgery to restore function. The choice of the type of operation lies with the surgeon and depends on many factors (area of ​​damage, nature, duration of injury, individual characteristics). In general, the complexity of the anatomical structure of the extensor apparatus of the fingers and hand requires the surgeon to have a thorough knowledge of anatomy and special training in the field of hand surgery.

Primary surgical treatment of the wound:

For acute open injuries, the first stage of treatment is primary surgical treatment of the wound, which includes washing the wound with mechanical removal of mechanical impurities and foreign bodies, excision of crushed and non-viable tissue, stopping bleeding, revision of the wound, in order to accurately identify all damaged structures and install the final diagnosis, as well as suturing the skin. In some cases, if appropriate conditions and qualified personnel are available, and there are no contraindications, primary surgical treatment of the wound can be supplemented with primary tendon repair.

Tendon suture – there are many different types of tendon sutures; the choice of a specific type depends on the area of ​​tendon damage and the skills of the surgeon. The main requirement for a tendon suture is to ensure strong, sufficiently long-term fixation and good adaptation of the ends of the tendon, even with multiple injuries.

Any surgery on the wrist flexor tendons is extremely difficult and must be performed by a qualified hand surgeon.

The intervention, if necessary, can be supplemented by intervention on nerves, blood vessels, ligaments and bones.

After the operation, a rigid plaster or plastic bandage is applied for a period of 4 weeks and rehabilitation treatment is prescribed, which should begin 1-2 days after the operation and includes physical therapy, physiotherapeutic procedures, paraffin therapy, and massage.

What does the basal phalanx of the finger mean?

The structural features and signatures of the basal phalanx reveal a relationship to the material sphere. But the material in this case does not refer to a specific substance, but to the ability to assimilate it, to integrate into this material reality. The basal phalanges show how intensely the intellect evaluates what is probed by the nail phalanges and received by the middle phalanges. In astrology, the basal phalanges correspond to the signs of the cardinal cross - Aries, Cancer, Libra, Capricorn.

The basal phalanges “solve” the question of material suitability or “penetrate” the real essence of things, the assessment of which begins with the nail phalanx of each finger.

The narrow, gentle beginning of the finger reveals talent for activity, a sense of reliability of facts and knowledge, sophistication of observations, critical perception of what is happening and literary talent.

A thickened basal phalanx speaks of insatiable material needs. Such people have insufficiently subtle feelings. They also lack intellectual mobility and the ability to conduct reasonable discussions.

The phalanges of the fingers are always considered in the ratio of their lengths.

A relatively long nail phalanx speaks of the spontaneity of assessments, the ability to express oneself, creative thinking, and spiritual mobility in the areas that this finger symbolizes. Intellectuals and thinkers have just such long nail phalanges.

The long middle phalanx reveals logical thinking, receptivity, thoughtfulness, natural understanding of the essence of things, fair criticism, the ability to speak, interpret words, conscious abilities of a creator and organizer, and the talent of a businessman in the areas that a particular finger symbolizes. At the same time, it is connected with the theme of human destiny - to collect experience.

A long, wide and fleshy molar phalanx indicates the ability to practically realize the inclinations characteristic of the upper phalanges of the fingers. It indicates significant power of action and implementation.

Fingers are used to perceive and embody external forces, and the lines on the fingers demonstrate the nature of these processes. These singatures can be compared to energy conductors.

Vertical lines on the basal and middle phalanx are normal. Through them, the signal is sent deep into the hand for processing. Clear, orderly, continuous and parallel longitudinal strokes indicate a balanced state of energy perception.

Vertical lines on the nail phalanx are rarer. They relate to the functions of the glands. But the correspondence of the fingers to certain secretory functions remains unclear. Henry Mangin, Claude Seago, Dr. J. A. Hüth, a specialist in the endocrine glands, and Dr. Mac Islaf have analyzed this topic extensively. Modern conclusions are also based on reflexology data.

1. Vertical lines on the nail phalanges:

• on the finger of Jupiter - excessive desire for leadership;

• on the middle finger - a pronounced interest in philosophy;

• on the ring finger - extreme sensitivity, excessive creative imagination, spiritual potential;

• on the little finger - refined feelings, spiritual sensitivity and the gift of self-expression, intuition, inspiration, fantasy.

2. Transverse lines on the nail phalanges, which are called “white lines,” reflect the stress suffered:

• on the index finger - depressed self-esteem, possibly as a consequence of social maladjustment;

• on the middle finger - a real loss of material assets, a threat to safety, stress due to unemployment or living conditions;

• on the ring finger - a predisposition to communicate, openness, but such a person is too critical and demanding;

• on the little finger - difficulties in communication, sexual problems.

3. Transverse lines on the middle and basal phalanges reveal internal rejection, blocking of those abilities that a certain finger expresses. Sometimes this is a favorable sign, because the transverse lines on the middle phalanx of the fingers of Jupiter and Mercury can indicate the acquisition of diplomatic abilities that allow one to get around sharp corners.

In chirology, it is customary to divide fingers into knobby and smooth. On narrow fingers, two types of phalangeal nodes are distinguished.

“Philosophical nodes” are the interphalangeal connections between the nail and middle phalanges.

In a positive sense, they mean analytical abilities, logic, organized thinking, and a penchant for philosophy.

Their negative influence: distrust, pettiness, intractability.

Nodes of a material or lower order connect the middle and basal phalanges. People with this feature of the hand consider everything from a purely practical point of view. They make decisions based on experience, respect laws and regulations, and strive for what can be realistically achieved.

Positive aspect: collection and analysis of facts.

Negative aspect: pettiness and spitefulness.

But there are also combined options, for example, on the philosopher’s hand there are both types of “knots”.

Surgical treatment

Syndactyly is treated only with surgical methods, most often on the fingers. Separation of the toes is indicated only in cases of inconvenience when walking and obstruction of the normal development of the leg.

The best age for surgery to separate fused fingers is considered to be between 4 and 5 years. With the end (terminal) type of syndactyly, surgical intervention is recommended to be performed at the age of 6-12 months, which is associated with a high probability of repeated deformation of the fingers during their growth.

Due to the age of the children, they are given general anesthesia (complete immobility is required). The duration of the operation depends entirely on the complexity of the case and can range from 30-40 minutes to 3-4 hours.

Types of surgical approaches during surgery:

  1. simple dissection of the skin membrane;
  2. dissection of the membrane with the need for plastic surgery with one’s own tissues;
  3. dissection of the membrane with the need for plastic surgery with local tissues and autografts;
  4. complex operations requiring muscle, tendon and bone grafting.
