De Quervains tenosynovitis is a painful condition caused by inflammation of two prominent tendons that are located at the wrist and thumb.
The two tendons called the Extensor pollicus brevis and Abductor pollicus longus originate from the middle of the forearm travel down towards and over the wrist to insert into the thumb. Collectively they function to extend the thumb, whilst abductor pollicus longus extends and also abducts the thumb (lifting thumb up to the ceiling).
What causes it?
The most common cause of De Quervains tenosynovitis is the repetitive overuse of thumb and wrist whether it is occupational or hobby related. For example, the repetitive thumb movement whilst using scissors by hair dressers, landscapers using shears or whilst gardening). Trauma to the tendons from injuries to the wrist or the thumb can cause inflammation of the tendons.
In some cases, age related degeneration of the tendon sheath or underlying conditions such as rheumatoid arthritis increases the risk of the developing De Quervains tenosynovitis. Hormonal changes resulting in fluid build up in young mothers can commonly result in De Quervains tenosynovitis.
Symptoms
Commonly your symptoms may include:
Pain located at base of your thumb
Pain elicited by movement of thumb (gripping or making a fist)
Grating or snapping feeling
Tightness in the wrist
Swelling surrounding the base of thumb and wrist
How is De Quervains tenosynovitis diagnosed?
Your doctor or physiotherapist will be able to diagnose the condition based on your symptoms and after doing a thorough movement assessment to rule out any other potential diagnosis.
Finkelstein test is used to elicit symptoms to confirm De Quervains tenosynovitis.
How to test:
Wrap your thumb with your fingers.
Slowly bend your wrist down
A positive test would elicit pain at the site of the two tendons.
Radiological investigations in lights of ultrasound and an x-ray might be recommended for further investigations, particularly to confirm clinical diagnosis or to rule out any other possible causes of De Quervains such as osteoarthritis.
What treatment options are available?
Conservative (non-surgical) management
Conservative management measures are generally recommended as the first line of management for mild to moderate symptoms. This is because up to 60-70% of symptoms are likely to improve over a period of 6-8 weeks of regular physiotherapy intervention. In this period, the following strategies are recommended by your therapist to fast-track your recovery
Rest and application of heat or cold packs
Avoid repetitive use of thumb
Pain medications (anti-inflammatory medications) such as diclofenac or ibuprofen
Splints or braces
Steroid injection
Surgical management
In more severe cases when conservative management has failed, surgery may be recommended by an orthopaedic specialist or surgeon.
Prior to your surgery you will have the opportunity to thoroughly discuss with your surgeon the details of the surgical procedure and about the post operative rehabilitation process.
Surgical procedure
Surgery may be performed under general or local anaesthesia. A small incision is made at the wrist and thumb region. The covering of the tendons (sheath) is then separated and expanded to provide the tendon space to allow the tendon to move smoothly within the sheath. After this the, the incision in then sutured with a firm dressing applied over the suture site.
While you recover from the surgery, an information sheet with post operative guidelines will be provided to you by your surgical team. It is important that you must follow the guidelines recommended by your surgeon for optimal recovery.
In most cases your will have a follow up with your surgeon few weeks after your surgery to check your wound healing and your progress. You are often times referred to physiotherapy for strength and conditioning of your wrist and hand movements to facilitate your recovery.
Rotator cuff injuries are the most common source of shoulder problems. They can range from minor sprains causing impingement type symptoms, to massive tears resulting in severe loss of function and pain. They commonly occur as a result of acute injuries (sports, falls), chronic overuse (repetitive loading) or due to gradual aging.
Anatomy of shoulder
The shoulder joint (glenohumeral joint) is the most mobile joint in the human body. It comprises of the humeral head (top portion of upper arm bone) which fits in the glenoid cavity of the scapula (shoulder blade) to create a ball and socket configuration. This anatomical configuration results in limited bony contact between the humeral head and the glenoid fossa, which reduces the stability of the joint.
Several passive and active structures stabilize and maintain proper biomechanics of the shoulder joint.
Passive stabilizers include the ligaments, joint capsule, cartilage and the bony concavity of glenoid fossa. Thick cartilage known as labrum lines the glenoid fossa to further deepen the groove by about 50% which is advantageous in stabilizing the shoulder joint during the articulation.
Dynamic stabilizers of the glenohumeral joint is gained from the coordination of rotator cuff muscles that compress the passive structures providing stability and mobility as whole.
The rotator cuff muscles include:
supraspinatus
infraspinatus
subscapularis
teres minor
Injury to any or all these four muscles, including the tendons that attach the muscles to bone can result movement dysfunction and severe pain.
Other important joints of the shoulder complex include:
sternoclavicular joint
arcomioclavicular joint
scapulothoracic joints
Types of rotator cuff pathology
Tendinitis and Tendinosis
More often than not the term tendinitis and tendinosis are interchangeably used to describe a similar tendon pathology. However, the factor that differentiates the two is the time of injury (acute or chronic).
Tendinitis results from acute injury to the tendon which sets off an inflammatory process characterized by pain, swelling, and redness. On the other hand, tendinosis is a chronic pathology that does not involve an inflammatory process. It is characterized by degeneration of collagen fibers in response to persistent micro-trauma, vascular compromise and aging.
Acute rotator cuff tear
Acute tears result from sudden forceful lifting of the arm against resistance or in an attempt to cushion a fall (for example, heavy lifting or a fall on the shoulder).
Chronic injuries
Most commonly resulting from occupational or sports requiring excessive repetitive overhead activity.
Signs and symptoms
Symptoms of a rotator cuff injury are due to the inflammation that accompanies the strain. Swelling that forms within the small space of the joint prevents the normal mechanics of the shoulder, resulting in the clinical picture of pain and decreased range of motion.
Acute rotator cuff tears
Tearing sensation
Immediate severe localised pain
Reduced strength
Symptomatic clicking
Reduced and worsening pain with movements
Affects daily activities (personal care, lifting, reaching etc)
Chronic rotator cuff tears
Generalized deep dull ache, sharp onset of pain with movements
Global shoulder weakness
Reduced movements and daily activities (especially moving to the side, reaching behind back)
When to seek medical treatment
See your doctor or a physiotherapist if you experience any of the following symptoms in the shoulder:
Pain, especially pain that does not improve with rest
Swelling, redness or tenderness around the joint
Shoulder weakness
Reduced shoulder movement
For more severe rotator cuff injuries, you may require immediate medical attention.
Seek immediate medical attention if you experience the following symptoms:
Sudden, severe pain
Visible joint deformity
Inability to move or use your shoulder joint
Sudden swelling, discoloration
Diagnosis
To diagnoses an injured rotator cuff, your physiotherapist will begin with a thorough subjective and physical examination of your shoulder.
Subjective assessment
Your physiotherapist will begin with a thorough subjective assessment inquiring about your signs and symptoms of an acute injury as well as any symptoms that may suggest a more long-term problem.
Physical assessment
The physical examination often involves observation to look for muscle wasting, deformities, and/or changes in appearance of the injured shoulder to the unaffected side. Your physiotherapist will also palpate different areas of the shoulder complex to find the area of pain or tenderness. Further examination will involve assessment of movement and strength to establish injury to muscles or tendons.
Radiology
In addition, your physiotherapist may refer you for imaging tests to diagnosis the cause of your symptoms:
MRI: provides detailed imaging of areas injured (referred by doctors, specialists or surgeons)
Treatment
Early diagnosis and treatment of a rotator cuff tear may prevent symptoms such as loss of strength and loss of motion from setting in.
Initial treatment of rotator cuff tendinitis involves managing pain and swelling to promote healing. This can be done by:
avoiding activities that cause pain
applying cold packs to your shoulder three to four times per day
taking anti-inflammatory medications like ibuprofen and naproxen
Rehabilitation plays a critical role in both the nonsurgical and surgical treatment of a rotator cuff tear.
When a tear occurs, there is frequently atrophy of the muscles around the arm and loss of motion of the shoulder. An individualized physiotherapy program is necessary to regain strength and improve function in the shoulder.
Physical therapy
Physiotherapy will initially consist of passive exercises to help restore range of motion and ease pain.
Once the pain is under control, your physiotherapist will prescribe exercises to help regain strength in your arm and shoulder.
Steroid injection
If you have persisting symptoms, your physiotherapist may recommend a steroid injection. This is injected into the tendon to reduce inflammation, which reduces pain.
Surgery
Surgery is recommended if you have persistent pain or weakness in your shoulder that does not improve with nonsurgical treatment. In which case, your physiotherapist will refer you to surgeon for an opinion of surgical intervention.
Exercises
Range of movement exercise
Pendulums
Lean forward with one arm hanging freely. Use your unaffected arm to brace against a chair for support.
With your affected side, gently swing the hanging arm from side to side, forward and back, and in a circular motion for 15-20 seconds each direction.
