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.

3d Printed Cast
   Jake Evill

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.

Super Squash

squash playersSquash is a racquet sport played with a small, hollow rubber ball by two or four players in a four walled court. Players alternate in striking the ball against the wall. 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 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-
