At this time of year, as athletes in many sports are getting ready for a new season, Dr Elkowitz advises three simple measures to reduce the risk of damage to the hands: strengthen, stretch, and protect.

Strengthening exercises that protect the hands and wrists are simple to perform and do not require special equipment. Athletes can build strength by squeezing a ball in the hand, doing wrist curls while holding a soup can or a light weight, or extending the fingers against the resistance of rubber bands placed around them.

Stretching should be part of every warm-up and can include simple stretches like extending the arm with elbows straight, and curling the hand to move the wrists up and down. Protection comes in the form of wrist guards, which can help prevent fractures, and gloves, which protect the palm from a direct blow and the skin from wounds and cuts.

Traumatic, Overuse Injuries

Injuries to an athlete’s hands or wrists are generally classified into two main categories: traumatic and overuse. Traumatic injuries usually involve acute pain resulting from impact or a specific event and are more likely to occur in athletes who participate in sports that require higher levels of contact (e.g., football, hockey, wrestling).

Traumatic hand injuries can result from a fall that forces the hand or fingers backward, a forceful impact to the hands, or a direct blow. Overuse injuries involve chronic pain that develops slowly and are sustained by athletes who participate in sports that require repetitive movements (e.g., baseball, tennis, golf).

Some common traumatic injuries in athletes include joint dislocations, sprains, muscle strains, broken bones, tendon inflammation, and ligament tears.

According to Dr Elkowitz, “Even seemingly minor injuries should receive prompt medical attention. Patients often can’t tell, for example, if a finger is broken. They may believe that if they can move it, it isn’t broken and they don’t see a doctor. But the only way to know for sure if the finger is fractured is with an x-ray. And a fracture left untreated can result in arthritis and considerable pain.”

The use of the hand and wrist in different sports affects the way they may be injured. For example, wrist fractures and sprains are among the most common sports injuries to the hands since they are often caused by falls, which are common in all athletic activities. When falling forward, most people react by putting their hands in front of them to cushion the fall.

This natural response causes landing on the palm, bending the wrist backwards and possibly stretching or tearing the ligaments connecting the bones in the wrist. The result is a sprain. Without an x-ray, a sprain often cannot be distinguished from a fracture, which usually results from falling on an outstretched wrist.

Baseball Finger, Tennis Elbow

Baseball finger, also known as mallet finger, occurs when a ball or other object forcefully hits the tip of the finger, bending it downward and damaging the extensor tendon, which straightens the finger. The finger is painful, swollen, and bruised and often the fingertip droops noticeably.

If an x-ray confirms that there is no fracture or misalignment of the joint, baseball finger can generally be treated nonsurgically. Many finger injuries occur during baseball when athletes slide head first into a base and jam their fingers into a base. This can be avoided by sliding feet first.

Tennis elbow is a common injury in which a tendon on the outside of the forearm fails and begins to tear away from the bone, with pain sometimes extending down the forearm. It is most often seen in those who play racket sports, but also affects individuals who participate in any activity that demands repetitive use of the forearm muscles (hand gripping and wrist turning activities).

Often tennis elbow can be exacerbated by having the wrong grip size. Players should have their local tennis pro evaluate their racket to have the correct size. Golfer’s elbow, while similar to tennis elbow, affects the tendon on the inner side of the elbow.

Extensor carpi ulnaris (ECU) tendonitis, also a common sports-related tendon injury, is an inflammation of the tendon that runs along the back of the wrist on the pinky side and is caused by repetitive twisting and backward flexing of the wrist.

It is most commonly seen in basketball players and those playing racket sports.

“These are some of the common injuries that affect the hand, wrist and arm,” says Dr Elkowitz. “There are many more, with varying degrees of severity. The important things for athletes to keep in mind are that ‘playing through the pain’ can result in serious, permanent damage and that simple preventive measures — strengthen, stretch, protect — can help athletes have a healthy season.”
