Cubital Tunnel Syndrome is a condition that involves pressure on the ulnar nerve (also known as the “funny bone” nerve) which can cause numbness or tingling in the ring and little digits, pain in the forearm, and/or weakness in the hand. This known as an Ulnar Neuropathy.
A diagnosis can be made by your specialist Physiotherapist or General Practitioner. Examination is very important to ensure the correct diagnosis made as this diagnosis can present in a similar way to other pathologies around the neck and shoulder area.
On observation, there may be atrophy (muscle wasting) of the intrinsic muscles of the hand pads, associated with certain aspects known as the hypothenar and thenar eminence. This may often lead to an abnormal claw posture of the 4th and 5th fingers – also known as Bishops deformity.
There are a number of mechanisms that lead to an ulnar nerve problem, but mainly it is caused as a result of direct pressure on the nerve causing impingement; known as a mechanical factors. Direct trauma or other space-occupying lesions may compress the ulnar nerve.
In addition, co-morbidities such as inflammatory arthritis, anatomical irregularities, metabolic disorders, congenital abnormalities and certain occupations which require repetitive bending and straightening of the elbow, may contribute to the development of cubital tunnel syndrome.
Your Physio will ask for a history of your symptoms proceeded by carrying out a clinical examination so that a precise and timely diagnosis can be given, ensuring the most effective treatment can be put in place immediately. Your Physiotherapist will work closely with you to set individualised treatment goals for you to aim at, and will regularly re-assess you to measure your progress and make any necessary modifications in your treatment.
Depending on the severity and irritability of your symptoms, your specialist Physiotherapist may initially recommend a splint to immobilise the elbow joint to reduce symptom severity. Alongside the use of a splint, medical management is often employed to treat symptoms including the associated neuropathic pain and inflammation. You will also be educated on the condition and your Physio will recommend useful strategies for performing certain activities in different ways to avoid aggravating your symptoms.
Your musculoskeletal clinician will devise a specific exercise programme for you, aimed at offloading the mechanical compression of the ulnar nerve and increase the resilience of the articulating soft tissue structures. Your Physio may also use hands on treatment techniques focused on reducing your pain and restoring any function which may be lost. You will be provided with ongoing advice and support so that you feel confident in managing your symptoms and preventing re-occurrence.
Often conservative management is utilised for 8-12 weeks before surgical consideration. In severe cases and where limited progress is made, a corticosteroid injection may be deliberated; particularly in those cases where cubital tunnel syndrome is associated with inflammatory arthropathies such as Ankylosing Spondylitis, Rheumatoid Arthritis, Gout and Psoriatic arthritis.
