Hoverboard Hazards

The exciting new phenomena of “hoverboarding” has made hoverboards one of the most popular technological “toys” on the market today.  Intended for agile adolescents, its appeal has also drawn parents and other adults nostalgic for those days gone by.

The technology of the hoverboard, known as a smartboard or balance board as well, doesn’t actually create a hover but rather a forward and backward motion on a sideways skateboard of sorts, with either a large single center wheel or two smaller ones at each end.  It is automated, can reach a formidable speed of 16 mph and relies on body movement for navigation. It is basically a hands free, self-balancing electric scooter.

Concern over hoverboard safety grows amid increase in injuries.

Concern over hoverboard safety grows amid increase in injuries.

They have become the vehicle of choice for students travelling around campus and preteens maneuvering around the house and down the street to visit friends.  They light up, are stealth quiet, move as fast as one’s imagination …. and leave hands free for any other activity desired on the fly.

Unfortunately, while the mainstream hoverboard never actually leaves the ground, its ability to send riders airborne is causing increasing concern.

In fact, the Consumer Product Safety Commission has reported receiving dozens of hoverboard-related injuries from across the United States.  Houston hospitals have also reported in a recent Associated Press article seeing a sharp increase in the number of hoverboard accidents sending adult and young riders alike to the ER and urgent care clinics.

Colleges are not only restricting their use on campus, as a result of the injury risk (to the user and passers by) but also the fire hazard their electrical system poses.  The hoverboard fire hazard is covered extensively in other hoverboard reports.

Among the most common musculoskeletal injuries seen from hoverboard use include concussions, fractures, contusions and abrasions.

Concussions

While most frequently seen in sports such as football and soccer, concussions are increasingly reported in hoverboard accidents.  With no recommended safety wear, the speed and maneuverability of the device is resulting in high impact falls and collisions – resulting in concussions. The primary symptoms of a concussion include:

  • Headache
  • Trouble concentrating, feeling “foggy”
  • Nausea
  • Delayed reaction times
  • Dizziness, lightheadedness
  • Sensitivity with bright lights or loud sounds
  • Irritability

 If a concussion is suspected, an evaluation should be conducted by a physician and hoverboard and other balancing activities should be avoided.

Fractures

Wrist fractures are among the most common types of fractures seen in hoverboard accidents – distal radius fractures among the most common type of wrist fracture.  This is often the result of breaking a fall or harsh impact with an outstretched arm. Other hoverboard fractures and dislocations have been seen in the fingers. Symptoms of a fracture or dislocation can be evident with extreme pain, swelling and slight disfigurement or subtle with only slight swelling and pain.

Most wrist fractures and finger fractures and dislocations can be treated nonsurgically, depending on the severity of the fracture or dislocation.  A splint or other bracing may be indicated, along with anti-inflammatory medication and rest/refrain from extracurricular activity.

Contusions and Abrasions

Collisions causing contusions and abrasions are frequently reported on hoverboards in the absence of safety gear. While most are minor cuts and scraps, some may result in open wounds requiring stiches, while potentially damaging nerves and other soft tissue.  Swollen, discolored injuries lasting more than a month should be further evaluated by a physician.

Preventing Hoverboard Injuries

The lack of safety standards and recommended safety gear/wear is a concern among hoverboard retailers and healthcare providers alike.  But, parents do not have to wait until such recommendations are established.  If a hoverboard is in your family’s future, take the proper precautions. As with any sport, safety gear recommended or not, will provide a bit of assurance.

Cyclists travelling at much less speeds not only have both hands and legs navigating a two-wheeled structure designed for the road, but also helmets, gloves, shoes and other gear designed for safety and the sport. This is also true of rollerbladers and skateboarders. Invest in the safety of your hoverboard rider and purchase protective safety gear.

Help young riders understand the potential risks for injury and encourage that they err on the side of caution to avoid the ER.

Have fun and be safe!

Summer Sideliners

Common summer injuries of the hand, wrist and elbow

As we hike, bike, raft and climb our way through summer adventure, mishaps are bound to happen.  Some of the most common we see include wrist fractures, tennis elbow syndrome and cuts and lacerations to the hand.

Recognizing and treating mishaps that may occur while maximizing these brief few summer months can make a difference in how ready we are for all that awaits us in the fall.

Wrist Fractures

The wrist is susceptible to injury, often used as a first line of defense to break a fall, shield us from impact and soften a blow.  The wrist is comprised of eight small carpal bones, two forearm bones (radius and ulna) and four articulations or joints – which allow the wrist to bend and straighten, move from side-to-side and twist with a broad range of motion.  A force to the hand and wrist may result in a fracture of any one or several of these bones.  While a fracture to one of the smaller carpal bones may only be visible on x-ray, more common distal radius fractures are usually evident – crooked or deformed in appearance.  A wrist fracture may cause pain and swelling and should be immediately addressed.

Tennis Elbow Syndrome (Lateral Epicondylitis)

Though named for the sport frequently causing the condition in tennis players, Tennis Elbow Syndrome is in fact most often caused by everyday activity and diagnosed in those who have never played tennis.  Affecting the outside (lateral) portion of the elbow, tennis elbow syndrome is considered an “overuse” condition.  It is the result of strain placed on the muscles and tendons that attach to the bone.  Also caused by trauma, tennis elbow syndrome can cause pain with gripping, lifting and grasping.

Cuts and Lacerations

Cuts and lacerations to the hand are very common during the summer months as our hands are integral in most outdoor activity and projects. Tendon lacerations are also often the result of trauma to the hand or fingers.  Tendon lacerations may affect either the flexor or extensor tendons.  These types of lacerations often also result in other deep structure damage and require surgical repair.  The cut ends of a tendon must be brought back together in order for the cells inside the tendon to begin the healing/repair process.  Preventing infection in an open wound is also a primary concern with these types of injuries.

 

The Different Types of Fractures

A fracture is a break in the bone. Within the hand and upper extremity it can occur anywhere from the fingertip to the shoulder.

Among the most common fractures and dislocations of the hand and upper extremity include:

  • Finger Fractures
  • Distal Radius Fractures (also called Colles Fracture)
  • Scaphoid Fractures
  • Forearm Fractures
  • Clavicle Fractures (collar bone)

There are a number of different types of fractures – partial or complete, simple or compound, clean or shattered …each with their own classifications.  It is important to first define the type of fracture and its severity before determining the most effective treatment plan.

Fractures are defined by the severity of the break and the impact it imposes to surrounding tissue. Some fractures known as partial fractures may only cause a slight crack in the bone, while others may result in a complete break or shattered bone.

A fracture may also be either open or compound, which is a fracture that pierces through the skin creating an open wound.  A closed or “simple” fracture is a fracture that does not break through the skin.

Other classifications that help determine the best treatment plan for your type of fracture include:

  • Transverse Fracture – A fracture that goes across the bone and is situated at a right angle to the long axis of the bone.
  • Greenstick Fracture – A fracture situated on only one side of the bone, causing a bend but not a complete break. These are most commonly seen in children with more “pliable” bones.
  • Comminuted Fracture – A fracture that results in three or more bone fragments.
  • Intra-articular Fracture – A fracture with joint involvement.

Depending on the severity of the fracture, treatment may entail the non surgical realignment of the bone and casting, also referred to as closed reduction. Or surgical repair utilizing fixation support may be indicated.

Wrist Fracture – Distal Radius Fractures Among the Most Common Wrist Fractures

X-ray of a Distal Radius Fracture, also known as a Colles Fracture

One of the most common hand and upper extremity fractures we see is a distal radius fracture.  This is because of its position at the end of the forearm bone where it meets the wrist and the essential involvement of our hands and wrist in everyday activities and sports.  Our hands and wrists are also the first line of defense in a trauma – used as a shield to soften the blow of a harsh impact or to break a fall.

There are many opportunities to injure the distal radius.

The radius is the larger of the two bones located in the forearm. “Distal” radius refers to the lower end of this bone where it meets the wrist. The other forearm bone is the ulna, and together these two bones form the radioulnar joint.

Also called a “Colles” fracture for the anatomist who first described it, a distal radius fracture is common among those involved in contact sports as well as those suffering from osteoporosis.  It is occasionally misdiagnosed as a sprain and improperly treated – which could eventually lead to joint instability and osteoarthritis.

Some of the symptoms associated with a distal radius fracture include:

  • Swelling
  • Weakness and reduced range of motion
  • Persistent pain
  • Possible numbness
  • Deformity

Once identified, initial treatment will depend on the severity of the fracture, other soft tissue damage, and the type of break (simple or complex).  A wrist fracture may be treated non surgically by manipulating the broken sections back into place (closed reduction) and stabilizing the wrist with a splint.  More severe breaks may require surgical repair.

Next month’s blog will discuss how fractures are categorized and how they determine the treatment selected.
