Initial Assessment and Diagnosis

Clinical Evaluation

The first step in managing a digital nerve injury is a thorough clinical evaluation. This includes:
- History Taking: Understanding the mechanism of injury (e.g., laceration, crush injury) and associated symptoms such as pain, numbness, or weakness.
- Physical Examination: Assessing sensory function (using monofilament tests or two-point discrimination) and motor function (evaluating the ability to flex and extend the finger) to determine the extent of the nerve injury.

Imaging Studies

In some cases, imaging studies such as ultrasound or MRI may be utilized to assess the extent of the injury and to rule out associated injuries to tendons or bones[1].

Conservative Management

Non-Surgical Treatment

For minor injuries or cases where the nerve is not completely severed, conservative management may be appropriate. This can include:
- Rest and Immobilization: Using a splint or buddy taping to immobilize the affected finger and allow for healing.
- Pain Management: Administering analgesics such as NSAIDs (e.g., ibuprofen) to manage pain and inflammation.
