From the Guidelines
The medical term for the index finger is "digitus secundus" or more commonly, the "second digit." Injuries to the index finger can have significant functional implications due to its crucial role in precision gripping, pinching, and pointing activities. Common conditions affecting the index finger include trigger finger (stenosing tenosynovitis), which may require corticosteroid injections or surgical release if conservative measures fail. Mallet finger injuries, where the extensor tendon is damaged, typically require splinting in extension for 6-8 weeks continuously. Fractures often need immobilization with buddy taping to the middle finger for 3-4 weeks, while more complex fractures may require surgical fixation. Osteoarthritis commonly affects the index finger joints, particularly at the DIP and PIP joints, and can be managed with NSAIDs like ibuprofen or naproxen for pain 1. Prompt treatment of index finger injuries is essential as complications can lead to permanent stiffness, deformity, or functional impairment, significantly affecting daily activities requiring fine motor skills and dexterity. Some key points to consider in the management of index finger injuries include:
- The use of radiographs for initial imaging to detect fractures or dislocations 1
- The potential need for MRI to evaluate tendon injuries, particularly for flexor tendon injuries or to assess the pulley system 1
- The importance of early diagnosis and treatment to prevent long-term complications and preserve function. It is crucial to prioritize prompt and appropriate treatment for index finger injuries to minimize the risk of long-term morbidity and mortality, and to maintain quality of life.
From the Research
Medical Term for Index Finger
- The medical term for the index finger is not explicitly stated in the provided studies, but it is referred to as the second finger or the finger that is affected by trigger finger (TF) in some cases 2, 3, 4, 5, 6.
Implications of Related Injuries or Conditions
- Trigger finger (TF) is a common pathology of the fingers that can cause functional deficit of the hand 2.
- TF can be treated conservatively with physical therapies such as external shock wave therapy (ESWT) and ultrasound therapy (UST) 3.
- Surgical treatment options for TF include percutaneous A1 pulley release and open A1 pulley release 4.
- Orthotic management of TF can be effective in reducing pain and improving function, with a recommended immobilization period of 6-10 weeks 5.
- The treatment of TF can vary depending on the population, with people with diabetes being a high-risk group, and the treatment method can impact the cost-effectiveness of care 6.
