Botox (Botulinum Toxin A) for the Treatment of Shoulder Pain

Shoulder Pain

Shoulder pain refers to any form of pain felt in the shoulder or around the shoulder joint. The shoulder joint is the most mobile joint in the human body, including four tendons that have the function of holding the muscle to the bone. Any swelling, inflammation, tearing or bony changes around the tendons in the shoulder causes pain when a person tries to move the arm upwards, backwards, straight out or in front.

Common causes include bursitis, rotator cuff tendonitis and tears or ruptures to any of the four tendons. Shoulder instability and dislocation is very common, leading to a host of conditions in this complex area of the body.

 

Botox (Botulinum Toxin A)

Patients that have easily identifiable trigger points, permanently contracted muscles, or headaches that are associated with muscle spasms are very good candidates for Botulinum Toxin A injections. Botox is the industry name for Botulinum toxin type A, which is derived from a strain of bacteria called Clostridium Botulinum. When Botox is injected into a muscle, it blocks the signals sent from the brain which tell the muscle to contract. Botox targets the muscles involved by effectively disarming them and ensuring that they do not send panic signals throughout the body. The body believes that there is no pain being experienced. Botox can help to keep the muscle relaxed for anywhere from three to six months, after which it is hoped that the muscle will be able to contract normally without pain or spasms.

 

Botox in Pain Management

 

Procedure

Botox injections are performed as an outpatient procedure at the London Pain Clinic, with patients free to leave as soon as the treatment has been administered. Initially, the treating doctor will spend time identifying the individual trigger points, sometimes with the help of a physiotherapist, and will mark the areas with a pen. The located areas will then be sterilised with a chlorhexidine antiseptic spray and a fast acting local anaesthetic will be will injected through a small cosmetic needle.

 

The Botox can then be administered by one of three different ways, depending on the case. Small cosmetic needles are usually preferred, but a Stimuplex nerve stimulator or ultrasound guidance are sometimes necessary if the trigger points are more difficult to access. 100 units of Botox are usually administered, but this can increase up to 200 units depending on the affected area.

 

Procedure Outcomes

One of the major advantages of Botox is that there is little or no recovery time, and most people feel fine and can return to their normal life immediately. The results of treatment should last around 3-6 months and the procedure can be repeated after this time.
