Upper Limb and Hand Pathology

Trigger Finger

OVERVIEW

Trigger finger affects the tendons in the fingers or thumb, restricting smooth movement. The condition is characterised by the digit getting stuck in a bent position and then suddenly straightening with a snap, resembling the action of a trigger being pulled and released.

CAUSES

Dr du Plessis   manages a range of tendinopathies that individuals may encounter. These include:

  1. Repetitive hand movements: Frequent and repetitive gripping or grasping motions can contribute to the development of trigger finger.
  2. Medical conditions: Conditions such as diabetes, rheumatoid arthritis, or gout can increase the risk of developing trigger fingers.
  3. Hand strain: Overusing the hand or fingers, especially during activities that involve prolonged gripping, can strain the tendons and contribute to trigger fingers.
SYMPTOMS
Recognising the symptoms of trigger finger is crucial for timely intervention:
  • Finger stiffness: The affected finger may be stiff, especially in the morning.
  • Popping or clicking sensation: A noticeable popping/clicking sensation when moving the affected finger.
  • Tenderness or a lump: Tenderness or the presence of a lump at the base of the affected finger.
TREATMENT
Dr Jason du Plessis employs a tailored approach to address trigger finger, considering the severity and individual characteristics of each case.
Conservative treatment:
  • Rest and immobilisation: Adequate rest and avoiding activities that aggravate the condition.
  • Anti-inflammatory medications: Non-steroidal anti-inflammatory drugs (NSAIDs) may be prescribed to reduce inflammation.
SURGERY
  • Release surgery (trigger finger release): For persistent or severe cases, Dr du Plessis may recommend a minor surgical procedure to release the constricted tendon sheath, allowing for smoother movement.

FAQ

What is the recovery time after trigger finger surgery?
The recovery time varies, but patients can typically resume light activities within a few days. Full recovery may take several weeks, and Dr du Plessis provides personalised guidance on post-surgery care
Are there risks associated with trigger finger surgery?
As with any surgery, there are potential risks, such as infection or nerve damage. Dr du Plessis thoroughly discusses these risks with patients and takes precautions to minimise them.
How can I prevent a trigger finger?
Preventive measures include avoiding repetitive gripping motions, taking breaks during activities that strain the hands, and maintaining good hand health. Regular hand exercises may also help prevent stiffness.
