Everyone has experienced that tingling sensation in the hands. It is commonly called “pins and needles” because it feels like tiny pointy needles. Some describe it as numb, or “falls asleep,” and is uncomfortable to place pressure on it.
The sensation itself is called “paresthesia,” or alternate sensation.
Sensation is transmitted from your body to your brain via nerves, your biological Internet cables. If you place too much pressure on one of them, the signal gets distorted. We call it Neuropathy, ie sick nerves. Once the pressure is relieved, it goes back online soon. If the pressure is not removed within reasonable time, it causes permanent change to the inner structure of the nerve and permanent change to the signal. More severe and long standing pressure can cause permanent loss of signal even. There are several nerves in the arm, and each may be subject to pressure at several spots. For more info, check the Numbness and Tingling page.

Cornell University just made a robot hand with a soft touch. it is not just soft, but it can also sense the shape and texture of what it comes into contact with.
Welcome to the growing field of soft robotics.

Today is my official first day as a full-time faculty at the West Virginia University Department of Orthopaedics, at the rank of Assistant Professor.

Harry Potter fans know very well that witchcraft can be dangerous.
Harry broke his ‘arm’ ( in reality, it was both-bone forearm fracture) during a Quidditch game and was ‘doctored’ by Professor Lockhart. The spell he used, Brackium Emendo, did not work as intended: instead of healing the bones, it made them disappear. Harry was then taken to the Hospital wing and treated with Skele-Gro, an awful tasting potion that grows missing bones.
I offer these few points to consider from an Orthopedic point of view:
This is a Sports injury! Should Quidditch players not wear protective ‘armor’?
Can this spell truly heal broken bones instantly? No cast! No Surgery! No down time! I should go spend sometime at Hogwarts.
Oops. The spell did not work after all. On top, it had the unintended consequence of missing bones: a Complication.
The ‘Doctor’ did not explain the treatment ( the spell itself), its risks ( missing bones), other alternatives ( let it heal with a cast), and did not get consent for treatment. In fact, Potter did not want him to cast the spell! In our world, it is an easy law suit!
The ‘credentials’ of the ‘doctor’ were suspicious to start with. Was he Witchcraft-Certified? even better for the law suit.
Skele-Gro was used to reverse the complication. Where can I get one? Would it work on stubborn fractures ( nonunions) and missing bone fragments? Yet another reason to visit Hogwarts.

Lucy, the famous 3 million years old hominin, has been a mistery for the last few years: how did she die? A group of orthopedic surgeons were asked to review recently obtained 3D CT scans of her skeletal remains and recognized something we are all too familiar with: fracture patterns of the shoulder and other bones that we see with high energy injuries in humans. Those were fractures that happened just before and led to her and not bone breakdown that happens to bone fossils.

Sports related injuries can be the result of a single trauma or due to repetitive overuse. Certain sports such as boxing, basketball, and volleyball have greater risk of injury to the bones, ligaments and muscles of the hand and wrist.
One common injury is a boxer’s fracture, which is a fracture of one of the metacarpal bones: it happens when your punch lands wrong.
Basketball and volleyball players frequently get ‘jammed’ fingers. This happens with a forceful encounter with the ball. There may be visible misalignment of the finger. A jammed finger can be anything from an innocent sprain to a bad fracture-dislocation requiring urgent surgery.
Looks can be deceiving and these injuries should never be underestimated.It is easy but costly to dismiss a serious injury. If pain and swelling do not go away in reasonable time, you should seek medical attention including proper x-rays.
Appropriately sized, and well applied hand wraps and/or gloves protect the hands from such injuries, and proper training is essential to prevent such injuries. Some of these injuries come with an easy fix while others require surgery and dedicated hand therapy.
While still recovering, you may still work on staying in shape and game ready by running, working on lower body and strengthening your core.Your treating physician, together with your therapist, will set the schedule and time frame towards full use and will let you know when it is safe to start exercising your injured hand.If you do too much too soon and push through pain, you may be delaying your recovery or reversing the outcome of your treatment.

My patient showed me today a neat trick to cover up the sharp edges of a Fiberglass cast.
She simply used a glue gun. The glue holds very well. In this case, for over a week. The edges are soft and it holds well to fiberglass. No more catching on clothes. She has not tried it close to her skin, and if you do want to try it, be careful not to burn yourself.

In 1996, an amateur archaeologist found a humerus bone north of Berlin. A flint arrowhead was embedded into the one end of the bone, ( funny it is nicknamed the surgical neck) prompting archaeologists to dig more. They found 130 people and five horses so far, and the bones were dated to about 1250 B.C.E., Europe’s Bronze Age. It is estimated that as much as 4000 warriors took part in the fighting- a large number for the bronze age which reflects significant advances in social organization to supports armies of this scale. “It could be the first evidence of a turning point in social organization and warfare in Europe,” one author said.

For several years, there has been a push to ban using powder in medical gloves. The US Food and Drug Administration (FDA) recently unveiled a proposal to ban powdered surgeons’ gloves and the absorbable powder lubricating them, as well as powdered gloves for patient examinations. Both synthetic gloves and those manufactured from natural rubber latex are covered.
Professional groups such as the American College of Surgeons, the American Academy of Allergy, Asthma and Immunology, and the American Nurses Association had already taken stands against powdered gloves. Government agencies such as the Centers for Disease Control and Prevention joined the chorus, as did the healthcare systems of Germany and the United Kingdom, as well as several healthcare organizations, such as Cleveland Clinic and Johns Hopkins, have either restricted or forbidden the use of these gloves.
Surgical gloves were first used in 1889, and soon, all sorts of lubricants were used to make them easier to don. Several studies has indicated respiratory complications.
