Abnormalities of fingers
Polydactyly
It is the presence of supernumerary fingers
Causes
- Congenital
- Familial
- Associated with VSD
- Laurence-Moon-Biedl syndrome
- Turner's syndrome.
It is the presence of webbed fingers. May occur in normal individuals or in those with, certain congenital abnormalities. It is seen in Poland's syndrome (absent unilateral pectoralis major muscle with TOF).
Arachnodactyly
It is the presence of Spider fingers. These are long and thin fingers.
Causes
- Marfan's syndrome
- Hypogonadism
- Hypopituitarism
- Homocystinuria
- Normal individuals.
Absence of one or more fingers may be congenital. Thumb may be absent in Fanconi's congenital aplastic anemia.
Sausage fingers
Thick and fleshy fingers seen in
- Acromegaly
- Myxoedema
- Psoriatic arthropathy.
Significance of posture of the patient
The position or attitude that is constantly assumed by a patient at rest or in motion is referred to as posture. The posture of a patient, when viewed from the side, may be characteristic enough to suggest an underlying diagnosis.
The various postures seen in clinical practice are the following :
1. Postures seen when the patient is standing / sitting.
- Vertical line seen in standing posture, when the patient is viewed from the side, is a good posture.
- Standing posture, when it assumes a S-shaped curve, when viewed from the side of the patient , is a poor posture.
- Asthenic posture : The normal curves of the spine are exaggerated in asthenic posture. Seen in debility, wasting and insenility.
- Parkinsonian posture : Universally flexed posture.
- Lordotic posture : There is an exaggerated lumbar lordosis.This is seen in muscular dystrophy, due to proximal muscle weakness.Lordotic posture is also seen in bilateral hip problems.
- Cerebellar posture : In lesions of the cerebellum or its connections, the patient stands with his feet wide apart, and is unable to maintain a upright steady posture when standing with both his or her feet placed close together. Patient is ataxic on standing (truncal ataxia) when the cerebellar vermis of is involved.
- Posture in ankylosing spondylitis : There is loss of the lumbar lordosis, and an exaggeration of the upper thoracic kyphosis.
- Catatonic posture : It is seen in schizophrenia. In this the patient maintains particular posture of the body and limb for hours together.
- Decerebrate posture : There is extension of elbows and wrists, with pronation of the arms is seen. This posture suggests that the lesion is at the brainstem level, disconnecting the cerebral hemispheres from the brainstem.
- Decorticate posture : There is flexion of elbows and wrists, with supination of the arms is seen. It suggests severe bilateral hemispherical damage above the midbrain.
- Hemiplegic posture : The patient lies on his back,with the cheek on the affected side blowing out with each time the patient expires. The affected upper limb lies flaccidly by his side, and the affected lower limb is externally rotated. This picture is seen immediately after the onset of hemiplegia. In long standing hemiplegia, there may be loss of naso labial fold of the face on the side of the paresis, with the affected upper limb in a flexed posture and the affected lower limb in an extended posture.
- Opisthotonus : In this posture the patient is arched up like a bow, with his or her heel and occiput in contact with the bed. This posture is seen in patients affected with tetanus and strychnine poisoning.
- The lateral decubitus posture with curled up limbs to minimise the stretching of the meninges, is seen patients with meningitis or meningism.
- Patient lying up with a back rest or cardiac rest (propped up posture )suggests a possibility of the patient having CCF or COPD.
- Patient sitting up and holding on to a support before him, in order to fix his shoulders, and the patient is dypneic suggests a diagnosis of bronchial asthma.
- Clutching his chest-suggest anginal chest pain
- Shallow breathing, with minimal or no movement of the anterior abdominal wall is seen in peritonitis.
- Clutching his chest is observed in Myocardial infarction.
- Holding his upper abdomen is seen in Biliary colic.
- Pericarditis
- Pancreatitis
Prone posture : Patient preferring to lie in the prone position than in the supine position may be due to the presence of an abdominal aortic aneurysm which may erode on the vertebra in the supine posture and this may cause back pain. On lying prone as the the aorta falls forward from the vertebra and the back pain subsides.
Pleuritic pain and pleural effusion patient may be seen lying on the affected side for relief of pain and dyspnea.
Clinical diagnosis based on body habitus
First impression of a patient's appearance will give certain clue that lead to diagnosis, but one should substantiate tha diagnosis by seeking for other signs on proper examination-these may be labelled as spotters.

Koilonychia and its causes
Koilonychia is the spoon-shaped deformity of the nail ,it is usually found in chronic iron deficiency anaemia.
Koilonychia develops due to the retarded growth of the nail plate. Koilos' means hollow and onych' means nail.
How will you examine for koilonychia ?
To examine for koilonychias first keep the patients finger at your eye level and look tangentially, you can observe as well as palpate the nail plate for spooning or flattening
What are the stages of koilonychia ?
There are three stages of koilonychia
First stage is characterised by brittle and rough nail
Second stage is charecterised by flattening of nail without longitudinal ridges and the nail is flat
Third stage the nail is spoon shaped and is concave.
What are the causes of koilonychia?
Causes of koilonychias are the following
- Iron deficiency anaemia
- Haemochromatosis
- Raynaud's syndrome
- Porphyria
- Occupational
Motor mechanics
Rickshaw pullers
- Ischaemic heart disease
- Syphilis
- Inherited—autosomal dominant.

How will you examine for clubbing ?
First step for examination of clubbing is
Bring the patient's lingers at examiners eye level and look tangentially.You should observe the onychodermal angle. If the angle is 180° or more, it is said that clubbing is present.
Second step for examination of clubbing
Very early clubbing can be detected by increase in fluctuation of the nail-bed it is due to softening of the nail-bed. To elicit 'fluctuation', the patient's finger (index finger) is placed on the pulp of examiner's two thumbs and held in this position by gentle pressure with the tips of examiner’s middle fingers applied on the patient's proximal interphalangeal joint. The patient's finger is now palpated over the base of the nail by the tips of examiner's index fingers. There is always some amount of fluctuation is present in normal fingers. Clubbing is said to be present when fluctuation is obvious here the palpation of the nail-bed may give the impression that the nail is floating on its bed.
For detection of clubbing, you should first examine the onychodermal angle and then the fluctuation.
What is the most reliable early sign of clubbing ?
Loss of normal onychodermal angle is one of the earliest sign is of clubbing increased fluctuation of the nail-bed although occur early is not always reliable.
Which fingers are affected first in clubbing ?
Usually the index finger is affected first in clubbing
What are the points to note when clubbing is detected?
- Unilateral or bilateral.
- Painful or not.
- Presence or absence of central cyanosis.
- Presence or absence of dyspnoea.
- The degree of clubbing.
Grade 1-Increased fluctuation of nailbed which lead to increased looseness of base of nail
Grade 2-Obliteration of nailbed angle more than or equal to 180 . It can be demonstrated by keeping the finger in profile view this is called profilesign
Grade 3-Parrot beaking—Biconvexity of nail
Grade 4-Drumstick nail-Bulbous enlargement of distal portion of fingers and toes
Grade 5-Hypertrophic osteoarthropathy-with the above mentioned features plus
- Thickening of periosteum
- Distal arthropathy
- Periosteal tenderness and heaviness of hands
Clubbing and its pathogenesis
Clubbing is the bulbous swelling of the terminal part of the fingers and the toes with an increase in the soft tissue mass, and increased anteroposterior as well as transverse diameter of the nails due to proliferation of subungual connective tissue.
Normal angle between the skin and the nail bed is 160 degree. It is also called as lovibond angle Obliteration of this angle is an early sign of clubbing.There is also increase in the soft tissue of distal part of the fingers and toes.This is manifested as biconvexity of nail and the bulbous distal portion of fingers.
In normal nails when the thumb nails are placed in opposion There is a lozenge shaped gap .In clubbing this gap is obliterated called as Schamroth's window test or sign.
What is the basic mechanism of clubbing?
Arterial hypoxemia and neurohumeral stimulus produces hypervascularity and opening up of anastamotic channels in the nail bed which lead to overgrowth of soft tissue.This is the basic mechanism of clubbing
Why the pulp tissue is increased in clubbing ?
Pulp tissue is increased due to
There are several theories to explain clubbing
Hereditary' predisposition - an autosomal gene of variable penetrance has been detected.
Vasodilators such as prostaglandins, bradykinins, 5-HT may be responsible for the development of clubbing. In bronchogenic carcinoma, vasodilator substances which are normally detoxified by lungs enters unaltered into systemic circulation
There is trapping of megakaryocytes and platelet clumps with local release of platelet-derived growth factor (PDGF) and other cytokines which increase the capillary permeability (latest and most acceptable theory). Arterial hypoxemia and neurohumeral stimulus produces hypervascularity and opening up of anastamotic channels in the nail bed which lead to overgrowth of soft tissue.
Possible mechanism of clubbing
The different hypothesis are

Why the pulp tissue is increased in clubbing ?
Pulp tissue is increased due to
- Proliferation of subungual connective tissue.
- Interstitial oedema.
- Dilatation of arterioles and capillaries.

Possible mechanism of clubbing
The different hypothesis are
- Anoxia- It is the most important theory which leads to opening up of deep arteriovenous fistula of the terminal phalanges. Fallot's tetralogy is an example
- Toxic - Example is SBE.
- Reflex theory- Vagotomy often improves the clubbing in bronchogenic carcinoma.
- Metabolic causes - Example is thyrotoxicosis.
- Humoral theory- Increased growth hormone, parathormone, bradykinin. eg. acromegaly. Pressure changes between the radial and digital arteries.
- Reduced ferritin (may escape oxidation in lungs and leads to dilatation of arteriovenous anastomosis by entering into systemic circulation) may play an important role (recent view).
