SPLINTS

Technically the term splint refers to a temporary device that is part of a treatment program.

 

Classification

• Static

• Dynamic.

 

Static Splints

Static splints have no moving parts, prevent motion and are used to rest or rigidly support the splinted part.

 

Uses: These are used to stretch joint contractures progressively or align specified joints after a surgical procedure for optimal healing. A static splint should never include joints other than those being treated and should be discontinued the moment its usefulness is over.

 

Disadvantages: Immobilization causes atrophy and stiffness.

 

Dynamic Splints

Dynamic splints are moving splints; their parts permit, control, or strengthen movement. The movement in a dynamic splint may be intrinsically powered by another body part or by electrical stimulation of the patient’s muscles. Extrinsic power may be provided by elastic bands or pulleys.

 

Uses: Dynamic splints provide prehension and also static positioning of the hand in a functional position.

 

General Functions of Splinting

• To prevent undesirable movements

• To provide a functional position for the hand.

• To reduce pain

• To hold fractured bone ends in position until they are united.

• To maintain the position after reduction of a dislocation until the joint capsule is healed.

• To strengthen specific muscles.

• To promote grip and pinch.

• To diminish muscle spasm

 

TYPES OF STATIC SPLINTS

 

Aeroplane Splint 

The Aeroplane splint maintains the shoulder in abduction and external rotation. It immobilizes shoulder and elbow joint. It consists of chest, arm, fore arm and wrist pieces joined to one another almost at right angles.


 

Indications

1. Erb’s palsy.

2. Supraspinatus tendon rupture

3. Avulsion of the greater tuberosity of the humerus.

4. Tuberculous arthritis of the shoulder joint.

5. Paralysis of the deltoid muscle

6. Abduction fracture of the neck of the humerus.

 

Advantages and Disadvantages

• The advantages of this splint are that it keeps the shoulder joint in its optimal position and does not confine the patient to the bed.

• The disadvantages are that it is inconvenient to the patient and that it tends to slide down the torso.

 

Cock-up Splint

The cock-up splint immobilizes, or stabilizes the wrist in dorsiflexion with volar or dorsal support . It may be static or dynamic. It allows full metacarpophalangeal flexion and carpometacarpal motion of the thumb. The splint should be worn all the time except during exercise and bath.



 



 

Indications: Wrist drop (radial nerve palsy) , hemiplegia.

 

 

Knuckle Bender Splint

Maintains the metacarpophalangeal joint in 90° flexion and interphalangeal joint in extension.

 

Function

• Immobilization of fingers.

• It provides support and stabilizes the wrist in extension.

• It maintains the transverse palmar arch.

• It assists in prehension.





Indication

• Total claw hand in case of medial and ulnar nerve injury, as in Hansen’s disease.

• Ulnar claw hand.

 

Hand Position: This splint comprises a light padded bar across the dorsal aspect of the proximal phalanges of the third and fourth fingers and a similar one over the upper end of the metacarpal. These are attached to another padded bar in the palm of hand by a small spring which pulls the metacarpophalangeal joints into flexion but allows the patient to extend them.

The interphalangeal joints of fingers are placed in extension. This is a typical example of a splint using the 3-point principle.

 

C-Splint

This splint maintains the thumb in abduction and partial rotation under the second metacarpal and supports it. It also stretches the first web space.

 

Indications

• Median nerve injury

• Contracture

• Burns.

 

OPPONENS SPLINTS

Short Opponens Splint

The short opponens splint maintains thumb in abduction and partial rotation under the second metacarpal. The wrist and other fingers are free.



Functions

• Immobilization of the thumb

• Improves prehension by providing a stable position against which the fingers can pinch.

• Protects the joint from pain.

• Stretches the web space.

 

Indications

• Low median nerve injury.

• Opponens transfer (6 weeks after surgery postoperative splint).

 

Dorsal Long Opponens Splint

This splint holds the thumb in abduction and partial rotation under the second metacarpal, and in addition supports the wrist dorsally in a functional position. The wrist is in 20° to 30° of dorsiflexion, and the thumb is abducted and rotated under the 2nd metacarpal, with the metacarpophalangeal joint in 0 to 5° of flexion. The interphalangeal joint is free unless required to be held in extension. Other fingers are free.



 

Function: To immobilize and protect the thumb.

 

Indications

• Scaphoid fracture

• Bennet’s fracture

• de Quervains tenosynovitis.

BRONCHIECTASIS

Dr. M. RAJESH, PT, B.P.T, M.P.T(cardio-pulmonary)
INTRODUCTION: Bronchiectasis means abnormal dilatation of the bronchi due to chronic airway inflammation and infection. It is usually acquired, but may result from an underlying genetic or congenital defect of airway defences. CAUSES: Congenital • Cystic fibrosis • Primary ciliary dyskinesia • Kartagener’s syndrome (sinusitis and transposition of the viscera) • Primary hypogammaglobulinaemia Acquired • Pneumonia (complicating whooping cough or measles) • Inhaled foreign body • Suppurative pneumonia • Pulmonary TB • Allergic bronchopulmonary aspergillosis complicating asthma • Bronchial tumours CLINICAL FEATURES: ● Chronic cough productive of purulent sputum.  ● Pleuritic pain. ● Haemoptysis.  ● Halitosis. Acute exacerbations may cause fever and increase these symptoms. Examination reveals coarse crackles caused by sputum in bronchiectatic spaces. Diminished breath sounds may indicate lobar collapse. Bronchial breathing due to scarring may be heard in advanced disease. INVESTIG...

CARDIAC REHABILITATION

Dr. M. RAJESH, PT, B.P.T, M.P.T(cardio-pulmonary)
  Introduction “Cardiac Rehabilitation is the process by which patients with cardiac disease, in partnership with a multidisciplinary team of health professionals are encouraged to support and achieve and maintain optimal physical and psychosocial health. The involvement of partners, other family members and carers is also important”. Cardiac rehabilitation is an accepted form of management for people with cardiac disease. Initially, rehabilitation was offered mainly to people recovering from a myocardial infraction (MI), but now encompasses a wide range of cardiac problems. To achieve the goals of cardiac rehabilitation a multidisciplinary team approach is required. The multidisciplinary team members include: Cardiologist/Physician and co-coordinator to lead cardiac rehabilitation Clinical Nurse Specialist Physiotherapist Clinical nutritionist/Dietitian Occupational Therapist Pharmacist Psychologist Smoking cessation counsellor/nurse Social worker Vocational counsellor Clerical Ad...

CARDIAC ARREST AND RESUSCITATION

Dr. M. RAJESH, PT, B.P.T, M.P.T(cardio-pulmonary)
INTRODUCTION: The leading causes of sudden death before old age, in people over the age of 44, are ventricular fibrillation from asymptomatic ischaemic heart disease or non-traumatic accidents such as drowning and poisoning. In people under the age of 38, the commonest causes are traumatic, due to accident or violence. In such instances death may be prevented if airway obstruction can be reversed, apnoea or hypoventilation avoided, blood loss prevented or corrected and the person not allowed to be pulseless or hypoxic for more than 2 or 3 minutes. If, however, there is circulatory arrest for more than a few minutes, or if blood loss or severe hypoxia remain uncorrected, irreversible brain damage may result. Immediate resuscitation is capable of preventing death and brain damage. The techniques required may be used anywhere, with or without equipment, and by anyone, from the lay public to medical specialists, provided they have been appropriately trained. Resuscitation may be divided in...

PARKINSON'S DISEASE

Dr. M. RAJESH, PT, B.P.T, M.P.T(cardio-pulmonary)
  Parkinson's EtiologyParkinson's disease (PD) is a neurodegenerative disorder that mostly presents in later life with generalized slowing of movements (bradykinesia) and at least one other symptom of resting tremor or rigidity. Other associated features are a loss of smell, sleep dysfunction, mood disorders, excess salivation, constipation, and excessive periodic limb movements in sleep (REM behavior disorder). PD is a disorder of the basal ganglia, which is composed of many other nuclei. The striatum receives excitatory and inhibitory input from several parts of the cortex. The key pathology is the loss of dopaminergic neurons that lead to the symptom .  It is the seconds most common neuro-degenerative condition in the world after Alzheimer's. The condition is caused by the slow deterioration of the nerve cells in the brain, which create dopamine. Dopamine is a natural substance found in the brain that plays a major role in our brains and bodies by messag...

RELAXED POSITIONS FOR BREATHLESS PATIENTS

Dr. M. RAJESH, PT, B.P.T, M.P.T(cardio-pulmonary)
Relaxation positions for the breathless patient  If patients can be taught how to control their breathing during an attack of dyspnoea, this can be of great benefit to them. The patient should be put into a relaxed position, and encouraged to do ‘diaphragmatic’ breathing at his own rate. The rate of breathing does not matter at this stage; it is the pattern of breathing that is important. As the patient gains control of his breathing he should be encouraged to slow down his respiratory rate. Any of the following positions will assist relaxation of the upper chest while encouraging controlled diaphragmatic breathing. They can be adapted to various situations in everyday life. HIGH SIDE LYING  Five or six pillows are used to raise the patient’s shoulders while lying on his side. One pillow should be placed between the waist and axilla, to keep the spine straight and prevent slipping down the bed. The top pillow must be above the shoulders, so that only the head and neck are supp...
