Cubital Tunnel Syndrome
The tunnel between tendons and ligaments on the inner elbow narrows and presses on the ulnar nerve, causing pain.
Of the arm's three main nerves, the ulnar nerve is important for fine, complex hand work. When it is compressed where it passes behind the elbow, it is called cubital tunnel syndrome.
Common causes
01
Degeneration from elbow overuse
02
Sleeping on your arm or keeping the elbow bent for long periods
03
Elbow fracture or trauma
Signs to watch for
- Numbness in the ring and little fingers and the elbow
- Ring and little fingers won't straighten fully or stay bent
- Dull sensation and weak grip; dropping things often
How we diagnose
X-ray
The basic first test. Further tests may be added for a definite diagnosis.
Ultrasound
Examines the joint while it moves, so problems that appear only in certain positions can be found. Inflamed areas can be treated with guided injections at the same time.
How we treat it
Early joint pain is usually treated conservatively first. If there is no improvement or symptoms last, more active non-surgical or surgical treatment may be needed.
Non-surgical injection therapy
Prolotherapy injects directly into weakened ligaments or tendons to reinforce the fibrous tissue, or a hyaluronic acid injection, a main component of joint fluid, is placed into weakened cartilage.
Extracorporeal shockwave therapy
Used across orthopedics, physical therapy and sports medicine, shockwave therapy aids recovery without surgery or painkillers and suits many conditions that cause acute or chronic pain.
Arthroscopy
Through a minimal incision under about 5 mm, an arthroscope with a tiny camera and special instruments is inserted into the joint. It shows areas that are hard to see on X-ray, allowing accurate diagnosis and treatment at the same time.
When surgery is consideredIf symptoms do not improve with conservative care, surgery is needed, usually arthroscopic decompression of the nerve.
