3D Printed Casting and Ultrasound Therapy

A cast on an arm usually requires that smelly, itchy sensation and the scary vibrating saw to remove it. The casts are pretty heavy themselves and the skin beneath gets minimal ventilation, increasing the chances of allergic reactions to the cast and delay in the healing process.

A big thanks to Jack Evill who came up with an idea of a cortex cast. His 3D printed exoskeleton cast provides support, allowing your arm to breathe and also get wet. Later an industrial designer named Deniz Karasahin heard about a system called Exogen, which is a Low Intensity Pulsed Ultrasound (LIPUS) devise designed to hasten the healing process of fractured bones. The problem was the transducer needed to touch the skin (something not possible with a regular cast) and thus, the device could not be used. Karasahin combined the 3D printed cast with Exogen. When used for 20 minutes a day, the system promises to reduce the duration of healing by 38% and increase the rate of healing by 80% in non-union fractures. It has completely revolutionized the field of orthopedics.

Exercises to Reduce Hand and Wrist Pain

keep your hands pain free!If you find that using your hand or wrist is difficult as of late, then you might be suffering from wrist tendonitis. This is a condition that arises out of overuse or excessive weight lifting, among other things. Any stress or strain on the wrist that overstretches the tendons and ligaments that form the joint could lead to swelling, pain, redness and difficulty in movements at this very vital joint. Depending on the severity of the pain, here are a few exercises that you can do to bring back the wring in your wrist.

  • Alternate flexion and extension-

Suspend your hand loosely in air from the edge of a table and bend the palm inwards towards the table. Hold it at the point of maximum bend (flexion) for 5 seconds. Slowly bring your hand back to a neutral position and then bend it backwards. Do not do this if it’s too painful. If it’s possible, do it gently and hold the maximally extended position for 5 seconds and release. Do the bending inwards and backwards alternately for 10 counts in each direction.

  • Alternate palm rotation-

Recovering from a Rodeo

cowboy hat‘Let’s go around’ is probably what the cowboy originally told the bull. Thus emerged the macho sport ‘Rodeo’ which is Spanish for ‘go around’. This sporting event involves livestock like horses, bulls, calves, steers with athletes typically known as cowboys or cowgirls. Various events are designed to test the skill and speed of the participants. It’s loved in places that are abundant in ranches and attracts an audience that is entertained by the display of machismo.

Super Squash

This sport was founded in New York in 1924 and then spread to America, Canada and eventually around the globe. Squash is an excellent form of cardiovascular workout. In one hour of squash, a player expends approximately 600-1000 kilo calories. Forbes 2003 rated squash as one of the healthiest games to play.

Squash is a game which involves moving around and changing directions rapidly. With all of this movement, chances of sustaining injuries are high. The best known squash injury is tennis elbow (although incidences are less common than tennis). Playing squash can injure your shoulder, elbow, wrist, hip, knee and ankle as these are used the most. Ocular injuries due to an oncoming ball should be avoided at all costs.

Exercises to Reduce Back Pain

oriental dancer backThe back bears the brunt of our mobility. The spine that helps us hold our head high and literally rise above other animals that walk the earth, pays a huge price for this anti-gravity action. It is essential that we take care of the back, especially the lower back that transmits the entire upper body weight to the lower limbs. Those who suffer from backache due to any reason realize the importance of this vital part of our skeletal and muscular system. Here are some tips that will help you deal with back pain to prevent you from becoming a slave to chronic backache.

  • Maintain correct posture- poor posture is one of the most common reasons for backache amongst people, especially those having sedentary jobs. A study confirmed that those with back pain compared to people with no back pain and those with a higher intensity of pain had higher tendencies to sway. This means that maintaining good posture is vital to prevent non-specific back pain that can often be disabling if chronic. Habits for good posture are sitting or standing erect, without stooping or hunching the shoulders.
  • Play sports- Engaging regularly in sports like swimming, running or walking in waist-deep water helps in maintaining back strength and stability. Studies have found that aquatic exercises are better than land-based exercises in regards to chronic lower back pain control.

The Aces of the Bases

boy baseballThe United States is one ‘Happy Nation’ when it comes to their national sport Baseball. Americans are ‘Aces’ whether it is in playing the game or being a mere spectator. The number of world cups bagged by Americans or the attendance of around seventy five million fans in professional games per year is ample proof of both.

Baseball is a field sport played on a diamond shaped field between two teams. Each team consists of nine players. It’s played with a ball which is made up of yarn wound around a cork covered with hide and a bat made up of wood in the shape of a stick. The team which scores the most runs wins the game. A pitcher throws the ball to an offensive player. A score is earned when an offensive player advances from the batter to the bases from the first, second, third and home base in counter clock-wise direction. As compared to other field sports like football, hockey or rugby, baseball is a less aggressive game. Injuries due to collision or trauma are lesser and more due to overuse of tissues.
