Tennis Elbow

Tennis Elbow

Tennis Elbow is a general term used to describe pain on the outside of the elbow. The most common causes is inflammation or degeneration of the tendon of the wrist extensor muscles as they insert into the elbow. It is also known as lateral epicondylitis or extensor tendinopathy.

Despite it's name, this condition is not only seen in tennis players but is also seen in other sports or recreational activities that involve repetitive stress on the muscles around the elbow, such as heavy lifting or decorating.

The injury can be very troublesome to treat, especially if it becomes chronic, so it is very important to obtain an accurate diagnosis as early as possible. Tennis elbow can either develop very suddenly (acute) or over a period of days/weeks and more gradually (chronic).

Tennis elbow symptoms

The main symptom is pain about 1 to 2 cm down from the bony part on the outside of the elbow, known as the lateral epicondyle. In addition, there may be associated weakness in the muscles around the forearm and wrist and this may cause difficulty in performing simple tasks with weakness gripping things, opening a door handle or shaking hands with someone.

A doctor or professional therapist may perform a number of assessment tests to help diagnose lateral epicondylitis. One test involves straightening the middle finger against resistance as this is often the most sensitive test and most likely to reproduce pain indicating possible epicondylitis. There are other tests that may be performed and these include the 'Mills maneuver' and 'neural tension' tests to assess the nerve tissue in the area. The reason for this is that similar injuries, such as the entrapment of the radial nerve as well as certain neck injuries can present with have similar symptoms.

What is tennis elbow?

It is usually an over use injury and most commonly occurs at the junction where the tendon of the extensor carpi radialis brevis' muscle inserts into the lateral epicondyle of the humerus (bony bit on the outside of the elbow near the 'funny bone'). In this area there are a large number of pain receptors making this region particularly tender to touch.

Acute injuries occur immediately after an activity such as hitting a backhand shot in tennis with poor technique. The extensor muscles on the back of the forearm (wrist extensors) become suddenly overloaded causing micro tears of the tendon where it attaches to the elbow.

Chronic injuries on the other hand normally develops over a period of days/weeks and usually follows bouts of intense exercise/activity that the patient is unaccustomed to, such as lifting heavy boxes when moving house.

The medical term is lateral epicondylitis but this can be misleading as the 'itis' on the end of the word implies that there is inflammation in the area but in most cases this is not true because most of the injuries are chronic or longstanding and therefore the inflammatory stage has finished.

Tennis elbow treatment

Treatment involves reducing symptoms of pain and inflammation through rest and applying ice or cold therapy, then gradually increasing the load through the elbow through exercises to a point where normal training and competition can be resumed.

Ice & compression - In the first 72 hours post injury, you should apply the principles of P.R.I.C.E. (Protection, Rest, Ice, Compression and Elevation). Apply a cold compression wrap for no more than 15 minutes as the injured tissues are very close to the skin and do not need longer.

Protection - Wear a specialist elbow brace or support can help reduce the strain on the tendon enabling healing to take place. This works by applying compression around the upper arm which puts pressure on the injured tendon, changing the way forces are transmitted through it allowing the injured tissues to rest.

Rest - this is probably the most impotant part of treatment and is often difficult to do. If you continue to use the painful elbow then it will not recover as quickly and may become chronic and very difficult to treat. Avoid gripping heavy things, opening heavy doors, using a screw driver and of course playing a backhand in tennis.

Sports massage can be a useful treatment for tennis elbow, particularly more chronic conditions. In particular cross friction massage of the tendon insertion but only once the initial inflammation has settled (after 5 day) is done. Place the 2nd finger of your opposite hand on the outside of the elbow and rub across the tendon (painful area) for 5 minutes. Do not press too hard but there may be some mild pain whilst having the area 'frictioned'. Repeat once a day. Do not carry on with this exercise if the pain worsens after the treatment.

A professional therapist or doctor may prescribe medication such as Ibuprofen to help reduce symptoms in the early stages, however the effectiveness of this long term is disputed. In addition electrotherapy such as ultrasound, laser, extracorporeal shock wave therapy, acupuncture, corticosteroid injections, nitric oxide donor therapy patches, botox injections and autologogous blood injection are all treatments available for treating medial epicondylitis.

Exercises

Both stretching and strengthening exercises are important and provide the foundation of a rehabilitation program. The exercises should be performed as soon as pain allows and then continued until and after full fitness has been achieved.

Wrist extension stretches and exercises are the most important with the aim of gradually increasing the load transmitted through the tendon and its attachment whilst also being within the limits of pain. Isometric (also known as static exercises) are done first and involve contracting the muscles without actually moving the wrist. They should only be started once the initial pain and inflammation has settled down.

Surgery

Both golfers elbow and tennis elbow are approached in a simliar manner which it comes to surgery. The vast majority of cases of tennis elbow do respond to conservative treatment of rest, ice, ultrasound and occasionally a steroid injection, however if however if surgery is required then it may be 8 weeks before the patient has recovered. See our interview with Mr Elliot Sorene, Consultant Surgeon who explains when surgery may be indicated and which patients are most suitable.
