Is your handbag going to give you arthritis?

Not to mention slipped discs and bad knees? How lugging around a heavy load can put years on your body!

By LAURA TOPHAM

Studies show half of women suffer pain from carrying heavy handbags — and now men are also suffering, according to new research by the British Chiropractic Association.

‘Heavy man-bags — weighing, on average, 6.2kg — put unbalanced strain and stress on the body, which can lead to pain, poor posture and health problems,’ says Rishi Loatey, of the British Chiropractic Association. ‘I’ve noticed a spike in patients experiencing pain in the neck and upper back due to carrying around heavy loads more frequently,’ he adds.

There, my movements while walking were recorded and analysed — both with and without my weighty 9lb-plus handbag — to see the effects. The results were startling.

‘Carrying a bag has a huge impact on posture and movement,’ says Bupa physiotherapist Russell Stocker. ‘Though you might not notice it, your body dramatically adapts and compensates. This was even more pronounced when wearing high heels.’

NECK

When you carry a bag, your neck naturally leans away from the load to help carry and balance the weight.

This causes tension on the carrying side of the neck and compression on the opposite side.

‘Craning your neck means increasing the distance between the neck and the shoulder,’ says Russell.

The problem is that this is just where a bundle of nerves come together (forming the brachial plexus) before running into the arm; the strain can lead to neck pain and muscle inflammation.

Over time, this could trigger an ‘acute episode’, he says — the muscles can spasm, restricting movement and causing pain.

SHOULDERS AND BACK

The shoulder bearing the load is rotated backwards and raised all the time, explains Russell.

This affects the muscles running down the upper back, the shoulder blades and those supporting the spine — they tire and spasm.

As Bupa orthopaedic physician Dr Leon Creaney, explains: ‘Fatigued muscles won’t hold the spine correctly, so it will slip into poor posture — slumped with curved back and shoulders.’

Long term, this can lead to painful arthritis in the facet joints. These are tiny joints running all the way along the spine on either side The vertebrae and the discs — the ‘cushions’ of cartilage that sit between the vertebrae — could also be affected. “The side of the body not carrying the bag leans away from it, crunching the lower back on this side, while extending it further on the other,’ adds Russell.

This compresses the vertebrae, wearing them down.

Carrying a heavy bag can, over time, also cause disc degeneration and prolapse, says Dr Creaney. This is when the soft tissue inside the disc ruptures out of it, pressing on the nerves.

‘This can be agonising, and even require surgery’ he explains — ‘and carrying a heavy bag could lead to faster disc degeneration.

‘Bearing a heavy load on one side could also cause the spinal nerves to become irritated or compressed — possibly leading to sciatica (pain in the buttock and thigh), which is also very painful.’

ARMS

The arm carrying the bag remains very static while walking to keep the load still and balanced.

‘This is quite different to the natural swinging movement we make when walking,’ says Russell.

‘Without the normal arm swing used as a balance mechanism, this can make you slightly unsteady and actually mean you need greater effort to move forwards.’

The nerves in the arms can also become irritated by the pressure of the bag, leading to chronic pain.

HIPS AND LEGS

In the long term, women can develop arthritis from increased pressure. ‘Carrying a bag makes you walk differently, and that changes the way forces act through the skeletal system, which could cause problems and pain,’ says Russell.

The greater the load of the bag, the more pressure on the leg joints. Over a long period, force on the knees can cause wear and tear and joint problems.

‘With a heavy bag you also take shorter steps — an adaptation your body probably makes to control the load better and remain upright,’ he adds.

Human bites that break the skin, like all puncture wounds, have a high risk of infection. They also pose a risk of injury to tendons and joints.Human bites may be more dangerous than most animal bites. There are germs in some human mouths that can cause infections that are hard to treat.

See the joy in Liam’s eyes as he is grasping a ball with his right hand for the first time. By the time this cute fellow grows up, he will have a bionic hand that will be connected to his neural-system and be indistinguishable from his biological body; but all Liam cares about for now his being able to play ball.

Repair of ventricular sepal defect

This photograph shows the surgical repair of a traumatic ventricular septal defect (VSD). A VSD is a hole between the right and left ventricles of the heart and is usually seen as a congenital condition, known as a ‘hole in the heart’. A traumatic VSD, as seen in this case, is a rare complication of chest injury. It might manifest immediately after trauma, leading to heart failure and an inability to stabilise a patient, or it might be delayed and detected months later. Traumatic VSDs can be treated in a variety of ways, depending on the effect they have on the patient. Treatment options range from monitoring and a conservative approach to open surgery, as is depicted here. In this image, the VSD is seen at the bottom, and a bovine patch is being parachuted and stitched into place to seal the defect.

AVRT (Atrioventricular reentrant tachycardia)

seen in patients with WPW syndrome.

electrical impulse make a circuit, which consists of an anterograde limb(normal pathway) and a retrograde limb(accessory pathway).

impulse start from atrium → AV node(anterograde) → His-Purkinje → ventricle → accesory pathway(retrograde)　→ back to atrium

narrow QRS regular tachycardia

negative P waves seen after QRS complex.

no delta wave, since antegrade conduction is not occurring via the accessory pathway

Wow I’ve never seen adenosine convert a rhythm that quickly. Every time I’ve given it, the asystolic phase lasts seconds! Probably one of my favorite drugs to administer.
